I have been reading about form model binding https://laravelcollective.com/docs/5.0/html#form-model-binding
It's very cool to populate DB values in html form.
I tried like this and this works fantastic.
{{ Form::model($university,array('url' => admin_path('universities/edit'),'id' => 'add_university','name' =>'add_university','data-validate'=>"parsley")) }}
{{ Form::label('university_name', 'University name',array('class'=>'control-label')) }}
{{ Form::text('university_name')}}
{{Form::close()}}
But the problem is here, Cause i want to add more attributes in input like class SO i am using
{{ Form::label('university_name', 'University name',array('class'=>'control-label')) }}
{{ Form::text('university_name','',array('class' => 'form-control'))}}
If i leave blank valuecolumn then nothing populate in textbox and if i using like this
{{ Form::label('university_name', 'University name',array('class'=>'control-label')) }}
{{ Form::text('university_name',$university->university_name,array('class' => 'form-control'))}}
Then what is use of model binding.
Please explain.
Thanks
{{ Form::text('university_name','',array('class' => 'form-control'))}}
It should be:
{{ Form::text('university_name',null,array('class' => 'form-control'))}}
'' means the real string, not null.
thanks, mathielo, for helping me on grammar

I simply want to give the text element of my edit-form a class.
{{ Form::text('first_name') }}
I know that i have to use an array with the class of the field as third argument. But i do NOT want to give a second argument. This one
{{ Form::text('first_name' , ' ' , array('class' => 'form-control')) }}
applys the class correctly, but sets the dafault value to an empty string. This is a problem, because now laravels auto-complete function doesn't fill the form with the correct data from the database. Is there a way to give no second argument or setting it to default like this?
{{ Form::text('first_name' , default , array('class' => 'form-control')) }}
Thanks!
Okay, i solved it myself. It is as easy as it always is. Simply use
{{ Form::text('first_name' , null , array('class' => 'form-control')) }}
I'm implementing bootstrap-slider in my CRUD, I have implemented it successfully in Create, the problem is when I try to edit it,
I want to get the current value from the Model. Idk how to do this.
This is for PATCH.
<div class="form-group">
<h3 class='box-title text-info'>Percentage</h3>
{!! Form::input('text','percentage',null,['id'=>'ex8', 'data-slider-id'=>'ex1Slider', 'data-slider-min'=>'0', 'data-slider-max'=>'100', 'data-slider-step'=>'5', 'data-slider-value'=>'50']) !!}
</div>
In your form instead of creating a new form. You will bind the form to the model.
{!! Form::model('modelname', [options here] !!}
All the fields will math the model's property values.
Edit
Here is an example
You must used something like this to create a EDIT FORM
{{ Form::model($smartphones, ['method' => 'PATCH', 'url' => 'smartphones/'.$smartphones->id]) }}
You get by using $(your_model)['inputID']...You can use in "data-slider-value"... Something like this
{{ Form::input('text','mem_ram', null, ['id' => 'mem_ram', 'data-slider-value'=>$smartphones['mem_ram']]) }}
{{ form_widget(form.category,{value:"3"}) }} //works!!
{{ form_widget(form.category,{value:'3'}) }} //works!!
{{ form_widget(form.category,{value:3}) }} // doesn't work !!
{{lastCatId}} // echos 3 !!!
{{ form_widget(form.category,{value:"lastCatId"}) }} //doesn't work ???
{{ form_widget(form.category,{value:'lastCatId'}) }} //doesn't work ???
I know after symfony 2.3. Value has to be quoted or double quoted. But I don't know why the variable doesnt work
never mind. I found the problem
{{ form_widget(form.category,{'value' : lastCatId|number_format }) }}
I had to cast it to int.
I have a problem and I can't resolve it, please help me. So I have my form :
{{ Form::open(array('url'=>'/administration/student/addMarks','method' => 'post')) }}
#foreach($aObjectsInGroupe as $object)
{{ Form::hidden('id_object[]',$object->id) }}
{{ Form::label($object->name) }}
{{ Form::select('note[]', $aMarks, null, array('class'=>'form-control')) }}
<br />
#endforeach
{{ Form::hidden('id',$aOneStudent['id']) }}
{{ Form::submit('Add mark',array('class'=>'btn btn-primary')) }}
{{ Form::close() }}
In my StudentController I have a method for get the mark from student_id and object_id:
public function getMarkByStudentAndObject($nIdStudent, $nIdObject){
$aMark = \Mark::where('student_id', '=', $nIdStudent)
->and('object_id', $nIdObject)
->get()
->toArray();
}
$aMarsks it's a table :
$aMarks = array(
'0'=>'0',
'1'=>'1',
'2'=>'2',
'3'=>'3',
'4'=>'4',
'5'=>'5',
'6'=>'6',
'7'=>'7',
'8'=>'8',
'9'=>'9',
'10'=>'10',
);
It's possible to call the method getMarkByStudentAndObject in :
{{ Form::select('note[]', $aMarks, null, array('class'=>'form-control')) }}
to get the selected value?
Help me please. Thx in advance.
maybe you need to do this:
<select name="note[]" class="form-control">
#foreach($aMarks as $key => $value)
<option value="{{ $key }}">{{ $value }}</option>
#endforeach
</select>
You should also check your Eloquent query, instead of ->and use another ->where
Try the lists() function of the Query Builder
\Mark::where('student_id', '=', $nIdStudent)
->and('object_id', $nIdObject)
->lists('column_1', 'column_2');
You then get the values of column_1 as the keys of the array and column_2 as the values.
http://laravel.com/docs/4.2/queries#selects
You should be able to directly call this from the Form::select. A call to
Mark::getMarkByStudentAndObject($aOneStudent['id'], $object->id)->note
would give you the Mark object and then you would need to get the note column which stores the value in the Mark object. Resulting in a call like this:
{{
Form::select(
'note[]',
$aMarks,
Mark::getMarkByStudentAndObject(
$aOneStudent['id'],
$object->id
)->note, array('class'=>'form-control')
)
}}
At the moment I can't verify if this is working because I have no possibility to test it but it should work as Blade is just a wrapper for PHP calls.
I need to input text name and id dynamically and I am trying as below
{{ Form::text('practice', $practice->name, array('class' => 'large-2','id'=<?php echo $inputTextName;?>)) }}
But it is not parsing PHP here. Even I tried 'id'={{$inputTextName}} but it is giving error.
Can you try this,
{{ Form::text('practice', $practice->name, array('class' => 'large-2','id'=>$inputTextName)) }}
