Is there some way to insert a blank option when creating a select input with the Laravel FormBuilder? I have this at the moment but I want to change it
{!! Form::select('tipo_id', ['blank' => ''] + $tipos, null, ['class' => 'form-control']) !!}
You cannot do too much better than you are already doing. Secret is to have array first element empty to show blank input.

I'm using laravel 9. I have stored data using summer note in the database, but it shows empty or null when I retrieve data from the database.
here is my code.
{!! Str::of($item->product_description)->limit(40) !!}
Try this
{!! Str::limit($item->product_description,40) !!}
I just started to use Laravel Collective. However, I encounter a problem when I try to extract the value from the Select Form.
{!! Form::open(['method'=>'POST','action'=>['ExpenseController#store'],'files' =>false], array('enctype'=>'multipart/form-data','id'=>'customer_contact','class' => 'form-validate1')) !!}
{{ Form::select('account_categories', $account_name,null, array("class"=>"dropdown-toggle form-control",'placeholder'=>'Please select ...')) }}
{!! Form::close() !!}
And it will look like this
But when I try to get the value from this select form via $request and return back to the Laravel, it output number instead of string value selected by user like this:
"account_categories":"5"
How can I get the string value selected by users from this SELECTBOX FORM ?
For some time I have a strange issue:
with standard syntax
{{Form :: radio ('somename', 'someval', true, ['adparam' => 'someparam'])}}
the parameter 'checked' does not render on the local host (mac, vagrant / box, laravel 5.4), but it works on a remote server ...
I have already broken the brain, in which direction to dig since I did not even notice the moment when it started work incorrectly (in fact, it worked some time ago)?
UPD:
A whole page is realy big, but the piece of code is
{{ Form::radio('certain', '1', true, ['data-case'=>$case->slug]) }} Возможный
{{ Form::radio('certain', '2', false, ['data-case'=>$case->slug]) }} Вероятный
{{ Form::radio('certain', '3', false, ['data-case'=>$case->slug]) }} Характерен для
{{ Form::radio('certain', '4', false, ['data-case'=>$case->slug]) }} Достоверный/Верифицированный
In fact, the issue shows up only when data in the controller matches with a view. If I have $case->certain and radio certain it does not work, but when I change radio name on some like certain2 it works but has no sense, of course. As I mentioned the issue exists only on localhost and just disturb to develop.
UPD:
After fighting with debugging tools I have found that servers handle param in different ways.
For localhost works:
{!! Form::radio('sex', 0, true) !!}
{!! Form::radio('sex', 1) !!}
{!! Form::radio('sex', 2) !!}
For production works:
{!! Form::radio('sex', '0', true) !!}
{!! Form::radio('sex', '1') !!}
{!! Form::radio('sex', '2') !!}
The Question: where is hidden a setting for this (etc 1!='1')?
You can't have multiple radio buttons selected. Radio button groups allow a single selection. You need checkboxes in order to accomplish multiple selections.
The issue comes down to using different database PDO drivers.
Some return ints as strings, others return it as an int. More here
Temp solution is
'mysql' => [
'options' => [PDO::ATTR_EMULATE_PREPARES => true]
],
in config in database.php
I have this form.
{!! Form::open(['action' => 'ArticlesController#store', 'method' => 'post', 'enctype' => 'multipart/form-data']) !!}
<div class="form-group">
Form::select('size', array(
'L' => 'Large',
'S' => 'Small'
));
</div>
{!! Form::close() !!}
The user will have a dropdown list to select Large (value: L) or Small (value: S). But if the user, let say, changes the value of any of those options using the dev tools, or whatever.
How can I validate the form if the user sends the 'size' field with a value that wasn't originally in the select options?
I mean, how can I check that the sent value is L or S, but not anything else.
Because the user could easily edit the form and send whatever value he wants to send, he could send a value that wasn't suppose to be sent.
I can do that using the validate class, but if instead of a 2 options list it is a 100 options list that'd be impossible.
Thanks!
This is how you can validate that:
$request->validate(['size' => 'required|in:L,S']);
this part after pipe "|in:L,S'" is used to check if the $request attribute value is equal to any value in that rule.

I have a form that has a select input that called customer_id. This field is not required, and I fetch the options via the Customer Model. My code looks like this:
{!! Form::select('customer', $customers->lists('email', 'id'), null, ['class' => 'form-control']) !!}
so far so good, right? but the thing is that when I don't want to choose a customer, I can't choose a blank option. Is there a way to add a blank option so I wouldn't need to pick a customer all the time?
[''=>'---']+$customers->lists('email', 'id')->toArray()
or
array_merge([''=>'---'], $customers->lists('email', 'id')->toArray())
