prevent old dates

Assistant

To prevent users from selecting past dates in your jQuery datetimepicker, you can set the `minDate` option to the current date and time. Here’s how you can modify your existing code:

jQuery('#start_date_time, #end_date_time').datetimepicker({
    format: 'd-m-Y H:i',
    minDate: 0, // Prevents selection of past dates
});

### Explanation:
– `minDate: 0` sets the minimum selectable date to the current date and time, effectively preventing users from selecting any date or time before now.

### Additional Options:
If you want to further customize the datetimepicker, you can look into other options like `maxDate` or event callbacks for more control. Here’s an example that sets both a minimum and maximum date:

jQuery('#start_date_time, #end_date_time').datetimepicker({
    format: 'd-m-Y H:i',
    minDate: 0, // Prevents selection of past dates
    maxDate: '+1Y' // Optional: Prevents selection of dates more than one year in the future
});

Make sure to include the jQuery and jQuery datetimepicker libraries in your HTML for this to work. If you have any further questions or need more assistance, feel free to ask!

onclick addmore add this in div id

Assistant

To implement an "Add More" functionality that adds an input field dynamically inside a specific “ when clicked, you can use jQuery. Below is an example that demonstrates how to achieve this.

### HTML Structure
Make sure you have a button to trigger the addition of new input fields and a “ to contain these fields:

<div id="reminder-container">
    <!-- Dynamic input fields will be appended here -->
</div>

<button id="add-more" type="button">Add More</button>

### jQuery Script
Now, add the jQuery code that listens for the button click and appends the new input field to the `#reminder-container` div:

jQuery(document).ready(function() {
    jQuery('#add-more').on('click', function() {
        // Create the new input field
        var newInput = `
            <input type="text" name="reminder_project_status[]" class="form-control projectreminder"
                placeholder="X days after project start" />
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);
    });
});

### Explanation:
– **HTML**: The “ with `id="reminder-container"` will hold all the dynamically added input fields.
– **Button**: The button with `id="add-more"` triggers the addition of new input fields.
– **jQuery**:
– The `$(document).ready()` function ensures the DOM is fully loaded before attaching event handlers.
– The `on('click', function() {…})` method attaches a click event to the button.
– The new input field is defined as a string (using backticks for template literals), allowing easy inclusion of HTML attributes.
– The `append()` method adds the new input field to the `#reminder-container` div.

### Additional Notes:
– Use `name="reminder_project_status[]"` for the input fields to make it easier to handle multiple inputs in your backend (they will be submitted as an array).
– If you need to preserve the old value for these dynamically added fields (e.g., when there are validation errors), you will need to manage that state accordingly, potentially with JavaScript or in your form processing logic.

give unique id

Assistant

To give each dynamically added input field a unique ID, you can keep track of a counter that increments each time you add a new field. Here's how you can modify the previous example to include unique IDs for each input field:

### HTML Structure
The structure remains the same:

<div id="reminder-container">
    <!-- Dynamic input fields will be appended here -->
</div>

<button id="add-more" type="button">Add More</button>

### jQuery Script
Here's the updated jQuery code to add unique IDs to each input field:

jQuery(document).ready(function() {
    let counter = 0; // Initialize a counter

    jQuery('#add-more').on('click', function() {
        counter++; // Increment the counter each time a new field is added
        
        // Create the new input field with a unique ID
        var newInput = `
            <input type="text" name="reminder_project_status[]" class="form-control projectreminder"
                id="reminder_project_status_${counter}"
                placeholder="X days after project start" />
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);
    });
});

### Explanation:
– **Counter Variable**: A `let counter = 0;` variable is initialized to keep track of how many input fields have been added.
– **Incrementing the Counter**: Each time the "Add More" button is clicked, the counter increments by one (`counter++`).
– **Unique ID**: The ID of the new input field is set using the counter value: `id="reminder_project_status_${counter}"`. This creates a unique ID for each input field in the format `reminder_project_status_1`, `reminder_project_status_2`, etc.
– **Appending the New Input Field**: The input field is then appended to the `#reminder-container` div as before.

This will ensure that every time you click "Add More," a new input field is created with a unique ID. If you have any further questions or need additional functionality, let me know!

User

jQuery('#add-more-projectrem').on('click', function() {
// Create the new input field
let counter = 0;
var newInput = `

// Append the new input field to the reminder-container div
jQuery('#reminder-container').append(newInput);
});
give row delete

Assistant

To add functionality for deleting a dynamically created input field (along with its associated "X" link for removal), you can use jQuery to listen for clicks on the delete link. You'll need to ensure that the counter for unique IDs is maintained correctly even after deletions. Here’s how you can implement this:

### Updated jQuery Script
Below is the modified script that includes a delete functionality:

jQuery(document).ready(function() {
    let counter = 0; // Initialize a counter

    jQuery('#add-more-projectrem').on('click', function() {
        counter++; // Increment the counter for each new input
        
        // Create the new input field with a unique ID and delete link
        var newInput = `
            <div class="input-group mt-1" id="reminder_project_status_div_${counter}">
                <input type="text" name="reminder_project_status[]" id="reminder_project_status_${counter}" class="form-control projectreminder"
                    placeholder="X days after project start" />
                <a class='removeprojectrem' data-id='reminder_project_status_div_${counter}' style="cursor:pointer; margin-left: 10px;">X</a>
            </div>
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);
    });

    // Delegate the click event to the remove link
    jQuery('#reminder-container').on('click', '.removeprojectrem', function() {
        // Get the ID from data-id attribute
        var divId = jQuery(this).data('id');
        
        // Remove the parent div containing the input field
        jQuery(`#${divId}`).remove();
    });
});

### Explanation:
1. **Counter**: The `counter` variable is used to create unique IDs for each input field and associated div.
2. **Creating Input Fields**: Each time the "Add More" button is clicked, a new input field is created inside a div. The unique IDs are set for both the input and the surrounding div.
3. **Delete Link**: A delete link ("X") is added next to each input field, styled as a clickable element with `cursor: pointer`.
4. **Delegated Click Event**: Instead of binding a click event directly to the remove link (which wouldn’t work for dynamically added elements), the event is delegated to `#reminder-container`. This way, any click on `.removeprojectrem` will trigger the removal function.
5. **Remove Functionality**: When the "X" link is clicked, the `data-id` attribute is used to identify the parent div of the input field, which is then removed from the DOM using `jQuery(`#${divId}`).remove();`.

### Usage
– When you click "Add More," a new input field is added.
– Clicking the "X" link next to an input field will remove that specific field.

This implementation allows for dynamic addition and removal of input fields. If you have any further questions or need additional features, feel free to ask!

User

jQuery('.projectreminder').datetimepicker({
format: 'd-m-Y H:i',
minDate: 0,
});
is not working when added dynamic row

Assistant

To ensure that the `datetimepicker` is initialized correctly for dynamically added input fields, you need to re-initialize the datetimepicker for those new elements after they are appended to the DOM. Here’s how to modify your existing jQuery code to achieve this:

### Updated jQuery Script
Add the `datetimepicker` initialization right after you append the new input field:

jQuery(document).ready(function() {
    let counter = 0; // Initialize a counter

    jQuery('#add-more-projectrem').on('click', function() {
        counter++; // Increment the counter for each new input
        
        // Create the new input field with a unique ID and delete link
        var newInput = `
            <div class="input-group mt-1" id="reminder_project_status_div_${counter}">
                <input type="text" name="reminder_project_status[]" id="reminder_project_status_${counter}" class="form-control projectreminder"
                    placeholder="X days after project start" />
                <a class='removeprojectrem' data-id='reminder_project_status_div_${counter}' style="cursor:pointer; margin-left: 10px;">X</a>
            </div>
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);

        // Reinitialize the datetimepicker for the new input field
        jQuery(`#reminder_project_status_${counter}`).datetimepicker({
            format: 'd-m-Y H:i',
            minDate: 0,
        });
    });

    // Delegate the click event to the remove link
    jQuery('#reminder-container').on('click', '.removeprojectrem', function() {
        // Get the ID from data-id attribute
        var divId = jQuery(this).data('id');
        
        // Remove the parent div containing the input field
        jQuery(`#${divId}`).remove();
    });
});

### Explanation of Changes:
1. **Reinitialize datetimepicker**: After appending the new input field, we immediately call `jQuery(`#reminder_project_status_${counter}`).datetimepicker({…});` to initialize the datetimepicker for the newly added input field. This is crucial because the `datetimepicker` does not automatically attach to elements that are added to the DOM after the initial page load.

2. **Counter Usage**: The counter ensures that each new input field has a unique ID, allowing for proper initialization.

### Full Example
Here is the full example including both adding and removing input fields with the datetimepicker functionality:

<div id="reminder-container">
    <!-- Dynamic input fields will be appended here -->
</div>

<button id="add-more-projectrem" type="button">Add More</button>

<!-- Include jQuery and datetimepicker scripts and styles in your HTML -->
<link rel="stylesheet" href="path/to/jquery.datetimepicker.css">
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="path/to/jquery.datetimepicker.full.min.js"></script>

<script>
jQuery(document).ready(function() {
    let counter = 0; // Initialize a counter

    jQuery('#add-more-projectrem').on('click', function() {
        counter++; // Increment the counter for each new input
        
        // Create the new input field with a unique ID and delete link
        var newInput = `
            <div class="input-group mt-1" id="reminder_project_status_div_${counter}">
                <input type="text" name="reminder_project_status[]" id="reminder_project_status_${counter}" class="form-control projectreminder"
                    placeholder="X days after project start" />
                <a class='removeprojectrem' data-id='reminder_project_status_div_${counter}' style="cursor:pointer; margin-left: 10px;">X</a>
            </div>
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);

        // Reinitialize the datetimepicker for the new input field
        jQuery(`#reminder_project_status_${counter}`).datetimepicker({
            format: 'd-m-Y H:i',
            minDate: 0,
        });
    });

    // Delegate the click event to the remove link
    jQuery('#reminder-container').on('click', '.removeprojectrem', function() {
        // Get the ID from data-id attribute
        var divId = jQuery(this).data('id');
        
        // Remove the parent div containing the input field
        jQuery(`#${divId}`).remove();
    });
});
</script>

### Important Note
Make sure to include the necessary jQuery and `datetimepicker` scripts and styles in your HTML to ensure that everything works correctly.

This setup will allow you to add new datetime input fields dynamically, and each field will have the datetimepicker initialized correctly. If you have further questions or need additional features, feel free to ask!

User

use class not id

Assistant

To use a class instead of an ID for the dynamically added input fields while ensuring that the `datetimepicker` is initialized properly, you can modify the jQuery code accordingly. Using a class is beneficial for situations where you want to manage multiple similar elements without dealing with unique IDs.

### Updated jQuery Script
Here’s how you can implement this:

jQuery(document).ready(function() {
    let counter = 0; // Initialize a counter

    jQuery('#add-more-projectrem').on('click', function() {
        counter++; // Increment the counter for each new input
        
        // Create the new input field with a class for selection and a delete link
        var newInput = `
            <div class="input-group mt-1 reminder-project-status">
                <input type="text" name="reminder_project_status[]" class="form-control projectreminder"
                    placeholder="X days after project start" />
                <a class='removeprojectrem' data-id='reminder_project_status_div_${counter}' style="cursor:pointer; margin-left: 10px;">X</a>
            </div>
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);

        // Reinitialize the datetimepicker for the new input field using the class
        jQuery('.projectreminder').last().datetimepicker({
            format: 'd-m-Y H:i',
            minDate: 0,
        });
    });

    // Delegate the click event to the remove link
    jQuery('#reminder-container').on('click', '.removeprojectrem', function() {
        // Remove the parent div containing the input field
        jQuery(this).closest('.input-group').remove();
    });
});

### Explanation of Changes:
1. **Class Instead of ID**: Each new input field now uses the class `projectreminder`, allowing multiple fields to share the same class without unique IDs.

2. **Last Input Selection**: After appending the new input field, the datetimepicker is initialized for the **last** input with the class `.projectreminder`. This ensures that only the most recently added input field receives the datetimepicker.

3. **Removing Fields**: When the "X" link is clicked, the closest `.input-group` div containing the input field is removed using `jQuery(this).closest('.input-group').remove();`. This keeps the code clean and efficient by targeting the correct parent element without relying on IDs.

### Full Example
Here’s the complete example with the necessary HTML, CSS, and JavaScript:

<div id="reminder-container">
    <!-- Dynamic input fields will be appended here -->
</div>

<button id="add-more-projectrem" type="button">Add More</button>

<!-- Include jQuery and datetimepicker scripts and styles in your HTML -->
<link rel="stylesheet" href="path/to/jquery.datetimepicker.css">
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="path/to/jquery.datetimepicker.full.min.js"></script>

<script>
jQuery(document).ready(function() {
    let counter = 0; // Initialize a counter

    jQuery('#add-more-projectrem').on('click', function() {
        counter++; // Increment the counter for each new input
        
        // Create the new input field with a class for selection and a delete link
        var newInput = `
            <div class="input-group mt-1 reminder-project-status">
                <input type="text" name="reminder_project_status[]" class="form-control projectreminder"
                    placeholder="X days after project start" />
                <a class='removeprojectrem' data-id='reminder_project_status_div_${counter}' style="cursor:pointer; margin-left: 10px;">X</a>
            </div>
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);

        // Reinitialize the datetimepicker for the new input field using the class
        jQuery('.projectreminder').last().datetimepicker({
            format: 'd-m-Y H:i',
            minDate: 0,
        });
    });

    // Delegate the click event to the remove link
    jQuery('#reminder-container').on('click', '.removeprojectrem', function() {
        // Remove the parent div containing the input field
        jQuery(this).closest('.input-group').remove();
    });
});
</script>

### Important Notes
– Ensure that you include the necessary jQuery and `datetimepicker` scripts and styles in your HTML file.
– This setup allows you to add and remove multiple datetime input fields without needing unique IDs, keeping your code cleaner and easier to maintain.

added input field not submitted when submit form'

Assistant

If the dynamically added input fields are not being submitted when the form is submitted, there are a few things to check:

1. **Form Structure**: Ensure that the dynamically created input fields are within the “ element.
2. **Proper Naming**: Make sure the name attribute of the input fields is set correctly so that they are submitted as part of the form data. In your case, it looks like you're using an array notation (`name="reminder_project_status[]"`), which is correct.
3. **JavaScript Errors**: Ensure there are no JavaScript errors that might prevent the form from being submitted.

### Example Form Structure
Here's an example of how to structure your form to include the dynamically added input fields:

<form id="reminder-form" action="your-action-url" method="POST">
    <div id="reminder-container">
        <!-- Dynamic input fields will be appended here -->
    </div>

    <button id="add-more-projectrem" type="button">Add More</button>
    
    <!-- Add other form fields here if needed -->
    
    <button type="submit">Submit</button>
</form>

<!-- Include jQuery and datetimepicker scripts and styles -->
<link rel="stylesheet" href="path/to/jquery.datetimepicker.css">
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="path/to/jquery.datetimepicker.full.min.js"></script>

<script>
jQuery(document).ready(function() {
    let counter = 0; // Initialize a counter

    jQuery('#add-more-projectrem').on('click', function() {
        counter++; // Increment the counter for each new input
        
        // Create the new input field with a class for selection and a delete link
        var newInput = `
            <div class="input-group mt-1 reminder-project-status">
                <input type="text" name="reminder_project_status[]" class="form-control projectreminder"
                    placeholder="X days after project start" />
                <a class='removeprojectrem' style="cursor:pointer; margin-left: 10px;">X</a>
            </div>
        `;
        
        // Append the new input field to the reminder-container div
        jQuery('#reminder-container').append(newInput);

        // Reinitialize the datetimepicker for the new input field using the class
        jQuery('.projectreminder').last().datetimepicker({
            format: 'd-m-Y H:i',
            minDate: 0,
        });
    });

    // Delegate the click event to the remove link
    jQuery('#reminder-container').on('click', '.removeprojectrem', function() {
        // Remove the parent div containing the input field
        jQuery(this).closest('.input-group').remove();
    });
});
</script>

### Key Points to Ensure Submission
1. **Form Element**: Wrap all your input fields and buttons inside a “ element. Ensure that the action attribute points to the correct URL where you want to handle the form submission.

2. **Form Submission**: The submit button in the form should have `type="submit"` for it to submit the form data.

3. **No JavaScript Errors**: Check the browser console (F12 or right-click > Inspect > Console) for any JavaScript errors that might be preventing the form from being submitted.

### Debugging Steps
– **Check Network Activity**: When you submit the form, open the Network tab in your browser's developer tools to see if the form data is being sent.
– **Print Form Data**: You can also temporarily add an event listener to log the form data when the form is submitted, to confirm that your dynamically added fields are included:

jQuery('#reminder-form').on('submit', function(event) {
        event.preventDefault(); // Prevent actual submission for testing
        console.log(jQuery(this).serialize()); // Log the form data
    });

If after checking these points the fields are still not submitting, please share any relevant error messages or behavior you're observing, and I'll help you troubleshoot further!
