ID generation for multiselects about html HOT 6 CLOSED

Can you please submit the full code that is causing the error and the full HTML generated? I need to see the full line without the ......

Thanks.

from html.

Template:
{!! Field::selectmultiple('categorias[]', [], [], ['label'=>'Categorias', 'multiple ', 'id'=>'categorias', 'data-placeholder'=>'Seleccione una o más Categorias', 'class'=>'chosen-select'] )!!}

Original code produces:

<select multiple="multiple " id="categorias[]" data-placeholder="Seleccione una o mas categorias" class="form-control chosen-select" name="categorias[]"></select>

causing var c = $('#categorias'); and var c = $('#categorias[]'); to fail

Updated Code produces:

<select multiple="multiple " id="categorias" data-placeholder="Seleccione una o más Categorias" class="form-control chosen-select" name="categorias[]"></select>

allowing

var c = $('#categorias'); to work and add selected and available items via jquery/ajax calls

from html.

the name of the field (categorias[]) doesn't make sense to me, can't it be just "categorias"?

from html.

Also if you'd like to have a field like post[categories] or something like that, write it as:

{!! Field::select("post.categories") !!}

The component will then generate the appropriate name post[categories] and the ID post_categories

from html.

If I name it just categorias, without the brackets,

the ajax call for saving data throws

Argument 1 passed to Illuminate\Database\Eloquent\Relations\BelongsToMany::formatSyncList() must be of the type array, string given, called in ...

$p->categorias()->sync($ct);

FormData (headers)
_token:zftpV77sX5ToChV7EYAnZifHGN2CkSkrBCOuGX7Y categorias:24 categorias:26 categorias:27 id:61

in the controller, where the form is submited a call to dd($request::get('categorias'));
returns just "27"

putting the brackets in the name, all works as expected.

Is a ManyToMany Relationship, where the edited model is submited with the selected categories its belongs. I've read in laravel docs and forums that multiselect name must include brackets to allow laravel submit this field as an array.

Also if you'd like to have a field like post[categories] or something like that, write it as >>"post.categories" the component will then generate the appropriate name post[categories] and >>the ID post_categories

Let me test it this way. The problem is than I'm filling selected and available categories via jquery/ajax/modal, and because of that, I'm can't use the laravel model/blade syntax in javascript/jquery calls. At least, don't know if is possible

from html.

You can see the same problem in core laravel form builder, back in 2013

laravel/framework#853

from html.
