Save multiple checkbox - Laravel 5.4 - php

Question

I need to save multiple checkbox to single field in the database.
<div class="checkbox">
<label>
<input type="checkbox" name="expresion_vegetal_id[]" value="1">Raíz
</label>
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="expresion_vegetal_id[]" value="3">tronco
</label>
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="expresion_vegetal_id[]" value="4">corteza
</label>
</div>
Controller:
$ficha_tecnica = new Ficha_Tecnica();
$options = $request->get('expresion_vegetal_id');
$ficha_tecnica->expresion_vegetal_id = $options;
$ficha_tecnica->save();
this is trying to save, the values ​​in [""], I need only save the numbers
insert into `fichas_tecnicas` (`expresion_vegetal_id`) values (["1","3","4"])
When I try to save, show the next message
1366 Incorrect integer value: '["1","4"]' for column 'expresion_vegetal_id'

Answer 1

You'r cannot add that because
You can try to loop the expresion_vegetal_id still in array format.
I see in your question is you need to add that in string format.
You must loop that array first and save one by one or you can used created
I give you the sample using loop.
You code will looks like this
$ficha_tecnica = new Ficha_Tecnica();
foreach ($$request->expresion_vegetal_id as $expresion_vegetal_id) {
$ficha_tecnica->fresh();
$ficha_tecnica->expresion_vegetal_id = $expresion_vegetal_id;
$ficha_tecnica->save();
}
i hope you can find the other same way....
