Laravel dropdown without optgroup - php

Question

I decided to try out Laravel and wanted to create dropdowns for my form. I created a convinience method inside my BaseController that I use to get the data from the database. Below is the function listing:
protected function getList( $model, array $fields, $empty = 'Select option below' )
{
$options = array();
$owner = strtolower( $model ) . 's';
$records = $model::lists($fields[1], $fields[0]);
if( !empty( $records ) ){
foreach( $records as $key => $value ){
$options[$owner][$value] = $key;
}
}
$options[$owner][''] = $empty;
return $options;
}
And then in the controller you can just use it like:
//Get groups
$groups = $this->getList( 'Group', array(
'name', 'id'
));
//Get Project Managers
$project_managers = $this->getList( 'ProjectManager', array(
'name', 'id'
));
The output of the select form control has an optgroup that references the owner of the list or the model rather. How can I remove the optgroup such that its not part of the contents of the dropdown?
Below is the output of the form:
<div class="input select">
<label for="project_manager">Project Manager</label>
<select name="project_manager_id">
<optgroup label="projectmanagers">
<option value="1">Riyaadh</option>
<option value="2">Luyanda</option>
<option selected="selected" value="">Select option below</option>
</optgroup>
</select>
</div>

Answer 1

You are adding another level within your getLists method with this line; $options[$owner][$value] = $key;, this is what is adding your optgroup, to get rid of this change the line to $options[$value] = $key;.
Optionally you can reduce the code of your getLists function to the following;
protected function getList( $model, array $fields, $empty = 'Select option below' )
{
$options = array();
$owner = strtolower( $model ) . 's';
$records = $model::lists($fields[1], $fields[0]);
if( !empty( $records ) ){
$options = array_flip($records);
}
$options[''] = $empty;
return $options;
}
This uses the array_flip method, which exchanges the keys as values and values as keys.

Try this...
$SchoolDetails = GeneralSettingModel::lists('SchoolName', 'id');
or
$SchoolDetails = DB::table('tablename')->lists('SchoolName', 'id');
{{ Form::select('SchoolName',array(''=>'Select School')+$SchoolDetails,null, array('id'=> 'SchoolName'))}}
Output:
<select id="SchoolName" name="SchoolName">
<option value="" selected="selected">Select School</option>
<option value="1">test</option>
<option value="2">test355wrew</option>
<option value="3">GOVT</option>
<option value="4">Kumaraguru</option>
<option value="5">valavan</option>
</select>

Answer 3

you can remove using JQuery by adding ID to select
$(function () {
$("#mySelect").children().remove("optgroup");
});

Answer 4

As Matt Burrow suggested it turned out that I was creating a multi-dimentional array which is translated to a list with optgroup.
I modified my function to rather exclude the owner which the records belong to. Below is my perfectly working function (excerpt):
...
if( !empty( $records ) ){
foreach( $records as $key => $value ){
$options[$value] = $key;
}
}
$options[''] = $empty;
