Laravel form checkbox data - php

Question

I have two tables; both of which have several columns. In one, I have all licenses the user can select (with checkboxes), in the other I store what licenses the user has.
I created a model to get all licenses, and model to get what licenses the user has.
Now, I can't understand how to create a view of all licences where those that the user already has are already checked - e.g when I create the form with these checkboxes, how can I check if the user already has the license.
I can get values but I cannot get the #if syntax work.
Here is my code currently:
<div class="form-group col-sm-12">
<div class="form-check form-check-inline">
#foreach($all_license as $all_licen_row)
#foreach($drive_licenses as $lisen)
#if($lisen->license_id==$all_licen_row->id)
<input class="form-check-input" type="checkbox"
name="{{$all_licen_row->license_id}}" checked>
<label class="form-check-label"
for="inlineCheckbox1">{{ $all_licen_row->class }}</label>)
#else
<input class="form-check-input" type="checkbox" name="{{$all_licen_row->license_id}}">
<label class="form-check-label"
for="inlineCheckbox1">{{ $all_licen_row->class }}</label>)
#endif
#endforeach
#if($errors->has('id'))
<span class="help-block">
<strong class="text-danger">{{ $errors->first('drive_licence') }}</strong>
</span>
#endif
#endforeach
</div>
</div>

Something like this is usually easier to handle without using an inner loop. You can check which id's should be selected before looping through $all_license by just storing the ids from drive_licenses into an array and simply check if the $all_license id exists in the array. Example:
<?php
$ids = array();
foreach($drive_licenses as $lisen) {
array_push($ids, $lisen->license_id)
}
?>
#foreach($all_license as $all_licen_row)
#if(in_array($all_licen_row->id, $ids))
<input class="form-check-input" type="checkbox" name="{{$all_licen_row->license_id}}" checked>
<label class="form-check-label" for="inlineCheckbox1">{{ $all_licen_row->class }}</label>
#else
...
#endif
#endforeach
If you want, you could also use the ternary operator (e.g., (?:)) to shorten your code some. Example:
#foreach($all_license as $all_licen_row)
<input class="form-check-input" type="checkbox" name="{{$all_licen_row->license_id}}"{{ (in_array($all_licen_row->id, $ids) ? ' checked' : '') }}>
<label class="form-check-label" for="inlineCheckbox1">{{ $all_licen_row->class }}</label>
#endforeach
