jQuery('#start_date_time,#end_date_time').datetimepicker({
format: 'd-m-Y H:i',
minDate: 0,
});
prevent to fill default date today

Assistant

To prevent the `datetimepicker` from filling in the default date with today's date, you can use the `value` option to explicitly set it to an empty string or avoid specifying a default date. Here's the updated code:

jQuery('#start_date_time,#end_date_time').datetimepicker({
    format: 'd-m-Y H:i',
    minDate: 0,
    value: '', // Ensures no default value is set
});

### Explanation:
– **`value: ''`**: This clears any default date that might otherwise be set.
– **`minDate: 0`**: Ensures that users cannot select dates earlier than today.

If the input fields still show today's date despite this setting, ensure that there are no other scripts or server-side code pre-filling the input values.

CarbonCarbon::parse($project->start_date_time)->format('d-m-Y H:i')
print current date if date is null

Assistant

To print the current date if the `$project->start_date_time` is null, you can use a ternary operator or the `??` null coalescing operator in PHP. Here's how you can modify the code:

CarbonCarbon::parse($project->start_date_time ?? now())->format('d-m-Y H:i');

### Explanation:
1. **`$project->start_date_time ?? now()`**:
– If `$project->start_date_time` is null, the `now()` function will be used to get the current date and time.
– If it has a value, that value is parsed and formatted.

2. **`format('d-m-Y H:i')`**: Formats the date to `day-month-year hours:minutes`.

### Alternative Approach:
If you're unsure whether `$project->start_date_time` is valid and want to avoid errors when parsing a null value, you can handle it explicitly:

$startDateTime = $project->start_date_time 
    ? CarbonCarbon::parse($project->start_date_time)->format('d-m-Y H:i') 
    : now()->format('d-m-Y H:i');

echo $startDateTime;

This ensures safe handling and avoids exceptions if `$project->start_date_time` is null.

but I don't want to show any date if nots avialbl

Assistant

If you want to avoid showing any date when `$project->start_date_time` is not available (null or empty), you can simply check its value and return an empty string if it's not set. Here's the code:

$startDateTime = $project->start_date_time 
    ? CarbonCarbon::parse($project->start_date_time)->format('d-m-Y H:i') 
    : '';

echo $startDateTime;

### Explanation:
– **`$project->start_date_time ? … : ''`**:
– If `$project->start_date_time` has a value, it is parsed and formatted.
– If it is null or empty, an empty string (`''`) is returned.

This approach ensures no date is displayed when the `start_date_time` is not available.
