Shorthand IF within Laravel HTML Form - laravel

I have a form input set up using the HTML facade:
{!! Form::text('name', NULL, ['class' => 'form-control ($errors->has("name") ? " has-error" : "")', 'placeholder' => 'Enter your name'] ) !!}
As you can I have put the $error->has inside the class but it is just printing the if statement as I know it would.
Is there anyway I can do what I am trying but keep on using the Form facade?

Try to put the if statement outside the single quotes:
{!! Form::text('name', NULL, ['class' => 'form-control'.($errors->has("name") ? " has-error" : "").'', 'placeholder' => 'Enter your name'] ) !!}

Text Area and Null, Laravel Collective

I've been using Laravel Collective for my forms and I seem to have encountered an issue with textareas. One that won't let me update null textarea fields with the same code I would use for a text field. I think the issue is with 'null' as it allows me to change the field if the textarea has text loaded. Does anyone know how to fix this so I can change null fields with textareas?
{!! Form::label ('otherinfo', 'Other information:') !!}
{!! Form::textarea ('otherinfo', null, array('class' => 'form-control', 'required' => '', 'maxlength' =>'1500') ) !!}
Your example should work fine. Make sure you update your Controller to accept and save the value that is present in $request->input('otherinfo').
<?php
$otherinfo = 'Hello World';
?>
<div class="form-group">
{!! Form::label('otherinfo', 'Other information:') !!}
{!! Form::textarea('otherinfo', $otherinfo, ['class' => 'form-control', 'size' => '50x3']) !!}
</div>

Unsupported operand types (View: C:\Users\10User\fyp2.2\resources\views\route\editRoute.blade.php)

Routes
Route::get('/editRoute/{id?}',['uses'=>'RouteController#edit' , 'as' =>'route.editRoute']);
Edit View blade
{!! Form::select('driver_id', ['$driver_id' => '---Select Driver---']+$drivers, null, ['class' => 'form-control']) !!}
Edit Controller
$routes = Route::find($id);
return view('route.editRoute', compact('routes'));
You can change that in one of two ways:
Add placeholder:
{!! Form::select('driver_id', $drivers, null, ['class' => 'form-control', 'placeholder'=>'---Select Driver---']) !!}
Change current select list:
{!! Form::select('driver_id', ['' => '---Select Driver---']+$drivers, null, ['class' => 'form-control']) !!}
Both option will work but first is my preferred :)

Laravel validation with input field as array "title[]" throws always the same error

No matter which validation rule i brake as long as i have an array notation in input name like this
<div class="form-group">
{!! Form::label('titile', '* Eventname: ', ['class' => 'control-label']) !!}
{!! Form::text('title[]', null, ['class' => 'form-control', 'required']) !!}
</div>
i get this error:
I have tried to use simple plain html input like this
<input type="text" name="title[]" />
and even like this
{!! Form::text('title', null, ['name' => 'title[]','class' => 'form-control', 'required']) !!}
But nothing works.
Only if i make the input field without array notation [] the validation works properly...
my validation rule is this
$this->validate($request, [
'title' => 'required|min:2',
]);
I don't know what else to do, if anyone had similar problem please help.
UPDATE:
i have tried it like this now with only one form input:
<div class="form-group">
{!! Form::label('title', '* Eventname: ', ['class' => 'control-label']) !!}
{!! Form::text('title', null, ['name' => 'title[]','class' => 'form-control', 'required', 'placeholder' => 'z.B. Deutscher Filmpreis']) !!}
</div>
-
public function rules()
{
$rules = [
];
foreach($this->get('title') as $key => $val)
{
$rules['title.'.$key] = 'numeric';
}
return $rules;
}
Write your validation in individual request file. This ('title' => 'required|min:2') validation does not work for array input. Try this technique for dynamic field validation.
public function rules()
{
$rules = [
];
foreach($this->request->get('title') as $key => $val)
{
$rules['title.'.$key] = 'required|min:2';
}
return $rules;
}
Very Good example at laravel news site.
https://laravel-news.com/2015/11/laravel-5-2-a-look-at-whats-coming/
OK i finally solved this. In Laravel 5.3 something is changed and you can't put empty array brackets for field name.
You must declare indices inside...for example:
this doesn't work
{!! Form::text('title[]', null, ['class' => 'form-control', 'required']) !!}
but this works
{!! Form::text('title[0]', null, ['class' => 'form-control', 'required']) !!}
UPDATE
So after solving this now i know that if you put empty [ ] brackets this will work if you have multiple input fields with same name...but if you put empty brackets and you have an option to add new fields dynamically like i did...then that single field with empty array brackets will fail because you actually don't have an array...and you must put [0] some indices inside...
and then it works

Laravel Form Model binding not showing data

I am trying to build a site and I get to the point where I would like to exploit the Form model binding
I set in the boot method of the RouteServiceProvider the binding between 'material' and 'App\Material' class
This is the creation Form:
{!! Form::open(array('url'=>'material', 'files' => true, 'class' => 'form-horizontal')) !!}
#include('admin_panel.partials.material_form',['submitButtonText' => 'Add'])
{!! Form::close() !!}
This is the include file:
{!! Form::label('title','Title',array('class' => 'control-label col-sm-2')) !!}
{!! Form::text('title','',array('class' => 'form-control')) !!}
{!! Form::label('published_at', 'Ready on:') !!}
{!! Form::input('date', 'published_at', date('Y-m-d'), ['class' => 'form-control']) !!}
{!! Form::label('file','Choose the material: ',array('class' => 'col-sm-2')) !!}
{!! Form::file('file') !!}
{!! Form::submit($submitButtonText, array('class' => 'btn btn-warning')) !!}
The operation of creating the material and save it to the db works perfectly.
When i want to edit a material before calling the edit view in the edit method of the MaterialController I use dd($material) to check if it is the correct object. The attributes (title, published_at,...) in the object on the screen are the correct one, so I am sure that the object I am passing to the edit view is the right one.
When i call the Edit View I print {!! $material->title !!} before the Form and the string is correct. This is the Form:
{!! Form::model($material, array('method' => 'PATCH', 'route'=>array('material.update', $material), 'files' => true, 'class' => 'form-horizontal')) !!}
#include('admin_panel.partials.material_form',['submitButtonText' => 'Update']);
{!! Form::close() !!}
The problem is that i don't see anything in the fields of the form...
I don't know where I made a mistake.
Thank you.
Well I made a stupid mistake.
In the Form::text (and I think also the other fields) of the include form I forced the second argument (the text displaying in the input text form to be empty instead of NULL, thus overriding the value of the bind model.
my mistake.

How to set a default value for a form partial variable in Laravel

I am implementing a simple controller for a mini-project of mine. For the simplicity of this question, only two views matter: the create song, and edit song views. Both of these views contain the same form fields, so I created a form partial called _form.
Since the forms have different purposes - despite having the same fields - I pass on to the partial a couple of variables to specify the value of the submit button label, and the cancel button route.
For example:
edit.blade.php:
(...)
{!! Form::model($song, ['route' => ['songs.update', $song->slug], 'method' => 'PATCH']) !!}
#include('songs._form', [
'submitButtonLabel' => 'Update',
'returnRoute' => 'song_path',
'params' => [$song->slug]
])
{!! Form::close() !!}
(...)
create.blade.php:
(...)
{!! Form::open(['route' => 'songs.store']) !!}
#include('songs._form', [
'submitButtonLabel' => 'Save',
'returnRoute' => 'songs_path'
])
{!! Form::close() !!}
(...)
And here is the _form.blade.php partial:
(...)
<div class="form-group">
{!! Form::submit($submitButtonLabel, ['class' => 'btn btn-success']) !!}
{!! link_to_route($returnRoute, 'Cancel', isset($params) ? $params : [], ['class' => 'btn btn-default', 'role' => 'button']) !!}
</div>
Now, my question is (finally):
As you can see, in the Cancel button of my form partial, I am using isset($params) ? $params : [] to default the $params variable to [] when it is not set.
Is there a better way to do this? Here, under Echoing Data After Checking For Existence, Laravel supports this alternative echo: {{ $name or 'Default' }}, but this does not work since I am trying to use it inside a {!! !!} block already...
So, is the ternary operator using the isset() function the best solution for this case? (The one I am currently using)
You can simply pass the variable $params an empty array ([]) in create.blade.php and remove the condition on your partial.
Then you can set the default value on your .blade files
As an alternative you can set a default value on your controller and send it as $params if they are not set (your slug).
Hope it helps
