Check checked checkbox in Laravel

Question

I have this code:

$arrayWithSelectedValues = [[user_id] => 3,[language_id] => 2], [user_id] => 3,[language_id] => 12]]

And I have checkbox :

@foreach($languages as $language)
<fieldset>
<input type="checkbox"
   class="icheckbox_square-red"
   id="input-15" name="languages[]"
   value="{{ $language->id }}">
<label for="input-15">{{ $language->name }}</label>
</fieldset>
@endforeach

How can I mark checkboxes as marked - those that have language_id from the array = $ language-> id?

Answer 1

Use the php function in_array() to check if the $language_id exists in the array of $languages

@foreach($languages as $language)
<fieldset>
<input type="checkbox"
   class="icheckbox_square-red"
   id="input-15" name="languages[]"
   value="{{ $language->id }}"
   @if(in_array($language_id, $languages))
      checked
   @endif
>
<label for="input-15">{{ $language->name }}</label>
</fieldset>
@endforeach

Answer 2

If $language->id value you are looking for, and you create an array of checked language ids from $arrayWithSelectedValues you can do:

<input
    type="checkbox"
    @if(in_array($language->id, $languages))
       checked
    @endif
>

You can collected the language IDs like so:

$languages = [];
foreach ($arrayWithSelectedValues as $selectedValues) {
    $languages[] = $selectedValues['language_id'];
}
