Help
I have two different form fields that are doing this (same form) the first part is a dependent dropdown and the second is a tree dropdown.
Here is all the code for the dependent dropdown. You select a manufacturer and it shows all the products for that manufacturer in the second.
model
//creates the dependent dropdown menu between company and products in _form.php 'product' => array(self::BELONGS_TO, 'Products', 'product_id'),
controller
public function actionProducts() {
{
$data=Products::model()->findAll('company_id=:company_id',
array(':company_id'=>(int) $_POST['company_id']));
$data=CHtml::listData($data,'id','model');
foreach($data as $value=>$name)
{
echo CHtml::tag('option',
array('value'=>$value),CHtml::encode($name),true);
}
}
}
Form
<div class="row">
<?php echo $form->labelEx($model, 'company_id'); ?>
<?php
$companies = CHtml::listData(Companies::model()->findAll(array('order' => 'id')), 'id', 'name');
echo CHtml::dropDownList('company_id','',$companies,
array(
'prompt'=>'Select Manufacturer',
'ajax' => array(
'type'=>'POST',
'url'=>CController::createUrl('Products'),
'update'=>'#product_id',
)
));
?>
</div>
<div class="row">
<?php echo $form->labelEx($model, 'product_id'); ?>
<?php echo CHtml::dropDownList('product_id','', array(),
array(
'style' => 'width:170px;',
'prompt'=>'Select Product Model',
));
?>
<?php echo $form->error($model, 'product_id'); ?>
</div>
This is the second field that isn't saving it is a tree dropdown. It pulls that data from the locations table and displays them in a parent child tree view in the dropdown. i.e.
1
-1.1
--1.1.1
2
3
-3.1
--3.2
---3.3
model
'parent' => array(self::BELONGS_TO, 'Locations', 'id'), 'children' => array(self::HAS_MANY, 'Locations', 'parent'),
form
<div class="row">
<?php echo $form->labelEx($model,'location'); ?>
<?php
$parents = Locations::model()->findAll('parent = 0');
$cm = new CommonMethods();
$data = $cm->makeDropDown($parents);
echo $form->dropDownList($model,'parent', $data, array('style'=>'width: 185px;', 'empty'=>'Please Select Location')); ?>
<?php echo $form->error($model,'location'); ?>
</div>
CommonMethods.php
<?php
class CommonMethods {
private $data = array();
public function makeDropDown($parents)
{
global $data;
$data = array();
$data['0'] = '';
foreach($parents as $parent)
{
$data[$parent->id] = $parent->name;
$this->subDropDown($parent->children);
}
return $data;
}
public function subDropDown($children,$space = '--')
{
global $data;
foreach($children as $child)
{
$data[$child->id] = $space.$child->name;
$this->subDropDown($child->children,$space.'--');
}
}
}
?>
Help with this would be greatly appreciated!
