Validate time in relation to a checkbox is checked or not? - laravel

Question

I have 3 input fields (reservationdate, starttime, endtime) and 1 checkbox (holeday).
If the checkbox clicked I do not need starttime and endtime. On the other hand starttime and endtime is required.
What can I do to solve this task?
I tried in Laravel the required_if validation-function. But I'm certainly using it wrong
// ReservationController store:
$data = $request->validate([
'userid' => 'required|numeric',
'vehicleid' => 'required|numeric',
'budgetid' => 'required|numeric',
'reservationdate' => 'required|date',
'starttime' => 'required_if:holeday,on|date_format:H:i|before_or_equal:endtime',
'endtime' => 'date_format:H:i',
'holeday' => 'boolean'
]);
index.blade.php (only the checkbox)
<div class="input-field col s2">
<label>
<input type="checkbox" name="holeday" class="filled-in" />
<span>Hole Day</span>
</label>
</div>
If the checkbox is checked I get the error-message "The starttime field is required when holeday is on." but in this case I need no error. Hey user it is OK. I don´t need a starttime or endtime. Your clicked the holeday.

Answer 1

Correct me if I am mistaken: you are trying to have starttime and endtime required only when holeday is not checked.
If I recall correctly when a checkbox is unchecked or disabled, it isn't sent at all to the server, so you can verify for the presence/absence of that field name:
// ReservationController store:
$data = $request->validate([
'userid' => 'required|numeric',
'vehicleid' => 'required|numeric',
'budgetid' => 'required|numeric',
'reservationdate' => 'required|date',
'starttime' => 'required_without:holeday|date_format:H:i|before_or_equal:endtime',
'endtime' => 'required_without:holeday|date_format:H:i',
'holeday' => 'required_without_all:starttime,endtime|in:on'
]);
Note: boolean validations accepts only true, 1``and "1" as thruthy values. But if the checkbox is set without a value attribute you would get "on" value as default check value.
However if you pass all of the three fields with their respective values, the validation would still pass, because required doesn't ensure that if the condition is not met that field must not be present.
You can take that into account and just write your logic to check if holeday has "on" value then ignore starttime and endtime values and viceversa.
Otherwise, you have to use a custom validation rule like this one (untested):
Validator::extend('not_present_with', function ($attribute, $value, $parameters, $validator) {
foreach ($parameters as $parameter) {
if (! Arr:has($validator->attributes(), $parameter)) {
return false;
}
}
return ! Arr::has($validator->attributes(), $attribute);
});
Then use the following validation rules:
// ReservationController store:
$data = $request->validate([
'userid' => 'required|numeric',
'vehicleid' => 'required|numeric',
'budgetid' => 'required|numeric',
'reservationdate' => 'required|date',
'starttime' => 'not_present_with:holeday|required_without:holeday|date_format:H:i|before_or_equal:endtime',
'endtime' => 'not_present_with:holeday|required_without:holeday|date_format:H:i',
'holeday' => 'not_present_with:starttime,endtime|required_without_all:starttime,endtime|in:on'
]);
