limit it to 3

Assistant

To limit the number of added services to a maximum of 3, you can use a counter to keep track of the number of dynamically added elements. Here’s an updated version of your code:

let serviceCount = 0; // Initialize a counter

$('.geodir-add-listing').on('click', '.addmoreservice', function() {
    if (serviceCount < 3) { // Check if the limit is reached
        $("#moreservicediv").append(`
            <div class="service-item">
                <input type="text" name="services_offered_service_name[]" id="services_offered_service_name" class="form-control">
                <a href="javascript:void(0)" class="addmoreservice">+</a>
                <a href="javascript:void(0)" class="removemoreservice">-</a>
            </div>
        `);
        serviceCount++; // Increment the counter
    } else {
        alert('You can only add up to 3 services.');
    }
});

// Handle removing services and updating the counter
$('.geodir-add-listing').on('click', '.removemoreservice', function() {
    $(this).closest('.service-item').remove(); // Remove the specific service
    serviceCount--; // Decrement the counter
});

### Explanation:
1. **Counter Initialization**: `serviceCount` is initialized to 0 to keep track of the number of added services.
2. **Limit Check**: Before appending a new service, check if `serviceCount` is less than 3. If not, display an alert.
3. **Counter Increment**: When a service is added, increment `serviceCount`.
4. **Service Removal**: Decrease `serviceCount` when a service is removed by clicking the `removemoreservice` button.

but one field already define

Assistant

If one service field is already predefined, then you need to initialize the counter to `1` to account for the existing field. Here's the updated code:

let serviceCount = 1; // Initialize the counter to 1 because one field is predefined

$('.geodir-add-listing').on('click', '.addmoreservice', function() {
    if (serviceCount < 3) { // Allow adding more fields only if the count is below 3
        $("#moreservicediv").append(`
            <div class="service-item">
                <input type="text" name="services_offered_service_name[]" id="services_offered_service_name" class="form-control">
                <a href="javascript:void(0)" class="addmoreservice">+</a>
                <a href="javascript:void(0)" class="removemoreservice">-</a>
            </div>
        `);
        serviceCount++; // Increment the counter
    } else {
        alert('You can only add up to 3 services.');
    }
});

// Handle removing services and updating the counter
$('.geodir-add-listing').on('click', '.removemoreservice', function() {
    $(this).closest('.service-item').remove(); // Remove the specific service
    serviceCount--; // Decrement the counter
});

### Key Adjustments:
1. **`serviceCount` Initialized to `1`**: Start the counter at 1 to account for the pre-defined service field.
2. **Logic for Adding Services**: Ensure the total fields (predefined + dynamically added) do not exceed 3.
3. **Removal Logic**: Decrease the counter when a service field is removed.

This will correctly handle the predefined field and ensure the total number of fields doesn't exceed 3.

remove + from 3rd item

Assistant

To remove the `+` (add more) button from the third service item, you can check the current count of service items when appending a new one and conditionally exclude the `+` button for the third item. Here's the updated code:

let serviceCount = 1; // Initialize the counter to 1 because one field is predefined

$('.geodir-add-listing').on('click', '.addmoreservice', function() {
    if (serviceCount < 3) { // Allow adding more fields only if the count is below 3
        let newServiceHtml = `
            <div class="service-item">
                <input type="text" name="services_offered_service_name[]" id="services_offered_service_name" class="form-control">
        `;

        // Add the "+" button only if it's not the 3rd item
        if (serviceCount < 2) {
            newServiceHtml += `<a href="javascript:void(0)" class="addmoreservice">+</a>`;
        }

        // Add the "-" button for all items
        newServiceHtml += `<a href="javascript:void(0)" class="removemoreservice">-</a></div>`;

        $("#moreservicediv").append(newServiceHtml);
        serviceCount++; // Increment the counter
    } else {
        alert('You can only add up to 3 services.');
    }
});

// Handle removing services and updating the counter
$('.geodir-add-listing').on('click', '.removemoreservice', function() {
    $(this).closest('.service-item').remove(); // Remove the specific service
    serviceCount--; // Decrement the counter

    // Ensure the "+" button is shown again if items are less than 3
    if (serviceCount < 3) {
        $('.addmoreservice').last().show();
    }
});

### Adjustments:
1. **Conditional `+` Button**: The `+` button is included only if the total service count is less than 3. For the third service, it's omitted.
2. **Ensure `+` Reappears**: When a service is removed, the `+` button for the last service is ensured to reappear if the count falls below 3.
3. **Dynamic Logic**: The HTML for each new service dynamically adapts based on the current count.

This ensures the `+` button is hidden for the third item and reappears when necessary.

let serviceCount = 1;

$('.geodir-add-listing').on('click','.addmoreservice',function() {
if (serviceCount < 3) {
$("#moreservicediv").append(`

+
–
`);
serviceCount++;
}
});
if we remove one then again need to add upon + click

Assistant

To handle the case where removing a service field allows adding a new one, you need to update the `serviceCount` when a field is removed and ensure the `+` button logic remains intact. Here's the updated code:

let serviceCount = 1; // Start with 1 because one service field is predefined

$('.geodir-add-listing').on('click', '.addmoreservice', function() {
    if (serviceCount < 3) { // Allow adding only up to 3 fields
        $("#moreservicediv").append(`
            <div class="service-item">
                <input type="text" name="services_offered_service_name[]" id="services_offered_service_name" class="form-control">
                <a href="javascript:void(0)" class="addmoreservice">+</a>
                <a href="javascript:void(0)" class="removemoreservice">-</a>
            </div>
        `);
        serviceCount++; // Increment the count
        updateAddMoreButton(); // Ensure the "+" button visibility logic is correct
    }
});

// Remove a service field and adjust the count
$('.geodir-add-listing').on('click', '.removemoreservice', function() {
    $(this).closest('.service-item').remove(); // Remove the service field
    serviceCount--; // Decrement the count
    updateAddMoreButton(); // Ensure the "+" button visibility logic is correct
});

// Function to manage "+" button visibility
function updateAddMoreButton() {
    // If the maximum number of fields is reached, hide all "+" buttons
    if (serviceCount >= 3) {
        $('.addmoreservice').hide();
    } else {
        // Show the "+" button for the last service item only
        $('.addmoreservice').show();
        $('.addmoreservice').last().show();
    }
}

// Initial call to set the "+" button visibility correctly
updateAddMoreButton();

### Explanation:
1. **Dynamic Count Adjustment**: The `serviceCount` variable increases when a field is added and decreases when one is removed.
2. **`updateAddMoreButton()` Function**:
– Hides all `+` buttons if the count reaches 3.
– Ensures the `+` button is visible only for the last service item when the count is less than 3.
3. **Remove Logic**: When a field is removed, the `serviceCount` is updated, and the `+` button for the last item is correctly displayed.

This approach ensures the system dynamically adjusts the visibility and functionality of the `+` button based on the current number of service fields.
