Question

I am using zend Framework Form, I am newbie in zend Framework and i want to display my check box form like this :-

*SK336
  *CP
  *PES
  *JCP
  *BGH
*SK996
  *KO
  *RTY
  *HGR
*SK547
  *GPK
*SK478
  *JUP

Note where :- * is check-box here

what i am trying is here :-

public function init()
{

  $parents = array();
     $childs = array();
     foreach ($this->Tagkey as $aResultDataValue) {
                    $parents [$aResultDataValue['parent']] = $aResultDataValue['parent'];
                    $childs [$aResultDataValue['parent']][] = $aResultDataValue['child'];
    }


    foreach ($parents as $parent){ // print_r ($parents); die();
    $tags = new Zend_Form_SubForm();
    $tags->addElements(array(   
    new Zend_Form_Element_MultiCheckbox('parent', array(
                    'multiOptions' =>   array($parent),
                    'filters'      => array('StringTrim'),
                    'validators'   => array(
                    array('InArray',
                          false,
                          array($parent))
                          )

       )),
       ));
    foreach ($childs as $child){
    $tags->addElements(array(
    new Zend_Form_Element_MultiCheckbox('child', array(
          'multiOptions' => array($child),
          'filters'      => array('StringTrim'),
          'validators'   => array(
                    array('InArray',
                          false,
                          $child)
                          )    
        )),
        ));
    }

    $this->addSubForms(array(
    'tags'  => $tags,
        )
    );
    }

I am able to create such type of structure in any .php page but not able to do that right now in zend framework form, I am using zend sub-form here.

Also I got an error right now when i am using this query

Warning: htmlspecialchars() expects parameter 1 to be string, array given in /var/www/dashboard_campaign/library/Zend/View/Abstract.php on line 905

Now i can understand your problem. I think it is to hard for handle that think from sub form. Try to use zend view scripts as following way.

Your form.php

public function init()
{
    foreach ($parents as $parent) {

        $parent = new Zend_Form_Element_Hidden($parent);
        $parent->setDecorators(array(
                array(
                      'ViewScript',
                       array(
                        'viewScript' => 'customviewscripts/parent.phtml',
                        'parent' => $parent           
                    )
                )
            );
       $this->addElement($parent);     
    }

}

file at views/script/customviewscript/parent.phtml

<?php

    $params = $this->element->getDecorator('ViewScript')->getOptions();
    $parent = $parems['parent'];

    $string = '<label>$parent['name']</label><input type="check" name="parent[]">';
    foreach ($children as $child) {
         $string .= <label>$child['name']</label>
                 . <input type="check" name=child[$parent[id]][]>' ;

    }

    print $string; 
?>

This is not the real solution. I percent only example. I think you can customize that. Most of developer use view script to make complex forms.

Your looking like mentioned wrong syntax for multi options John, you should try this.

Remove array for $parent see example below.

 new Zend_Form_Element_MultiCheckbox('parent', array(
                'multiOptions' =>  $parent,
                'filters'      => array('StringTrim'),
                'validators'   => array(
                array('InArray',
                      false,
                      array($parent))
                    )

From db results you have to produce following type of array for the $parent variable

$parent variable should like this for example copy this array and try your self without fetching from database,you will see all options

$parent=Array ([1] => blah1 [2] => blah2 [3] => blah3 [4] => blah4 [5] => blah5);

Check this one also for multiple check boxes, in place of array you should try placing array variable, I havn't tried this just looked at internet but should work fine.

$category1 = new Zend_Form_Element_MultiCheckbox('categories',Array())
$category1->setLabel('Category 1');

$category2 = new Zend_Form_Element_MultiCheckbox('categories',Array())
$category2->setLabel('Category 2');

... later...

 $this->addElement($category1)
 ->addElement($category2);
