如何从php中的zend框架表单调用数据库 - how to call database from zend Framework forms in php

我现在有了以下php脚本，我想把他的脚本放在zend格式中。这是我到目前为止的代码：-

$parents = array();
$childs = array();
foreach ($this->Tagkey as $aResultDataValue) {
        $parents [$aResultDataValue['parent']] = $aResultDataValue['parent'];
        $childs [$aResultDataValue['parent']][] = $aResultDataValue['child'];
}
foreach ($parents as $parent) {
     echo '<div>';
     $parent_value = "'$parent'";
     echo '<div><input type="checkbox" name="parents[]" value="'.$parent.'" id="'.$parent.'" class="parentCheck"/>
     <label for="parents_'.$parent.'">'.$parent.'</label></div>';
         foreach ($childs[$parent] as $child) {
           $child_value = "'$child'";
               echo '<div style="margin-left:15px;"><input type="checkbox" name="childs[]" value="'.$child.'" id="childs_'.$child.'" class="child_'.$parent.'" onclick="checkParent('.$parent_value.','.$child_value.');"/>
              <label for="childs_'.$child.'">'.$child.'</label></div>';
     }
     echo '</div>';
}

现在我将使用zend形式的纯php脚本，我正在尝试的是：-

类Admin_Form_Users扩展Zend_Form｛

public function init()
{   
   $parents = array();
      $childs = array();
      foreach ($this->Tagkey as $result) {
        $parents [$result['parent']] = $result['parent'];
        $childs [$result['parent']][] = $result['child'];
        }
       foreach ($parents as $parent) {
       $subForm = new Zend_SubForm();
       $subForm->addElement($parent);
       foreach ($children as $child) {
           $subForm->addElement($child);
       }
       $form->addSubForm($subForm);
    }      

        $parent = new Zend_Form_SubForm();
        $parent->addElements(array(
            new Zend_Form_Element_MultiCheckbox('subscriptions', array(
                'label'        =>
                    'Which parent would you like to subscribe to?',
                'multiOptions' => $parents,
                'required'     => true,
                'filters'      => array('StringTrim'),
                'validators'   => array(
                    array('InArray',
                          false,
                          array(array_keys($parents)))
                )
            )),
        ));
        $child = new Zend_Form_SubForm();
        $child->addElements(array(
            new Zend_Form_Element_MultiCheckbox('subscriptions', array(
                'label'        =>
                    'Which child would you like to subscribe to?',
                'multiOptions' => $childs,
                'required'     => true,
                'filters'      => array('StringTrim'),
                'validators'   => array(
                    array('InArray',
                          false,
                          array(array_keys($childs)))
                )
            )),
        ));

         $this->addSubForms(array(
        '$child' => $child,
        'parent' => $parent
    ));

我收到一个错误

Warning: Invalid argument supplied for foreach() in /var/www/dashboard_campaign/application/modules/admin/forms/Users.php on line 19

这里的意思是：-foreach ($this->Tagkey as $aResultDataValue) {

Tagkey来自数据库模型

我能做什么我是zend框架中的newbie我做错了什么帮助我

$TagKey不是Zend_Form的成员，我不知道它被添加到了哪里。

您可以将TagKey来自的模型传递到表单的构造函数中，或者在表单的init()方法中，您需要创建模型的实例并获取TagKey变量。

以下是如何将它从控制器中获取到表单对象中。

public function editAction()
{
    $tags = new Campaign_Model_DbTable_Tag();
    $aResultData = $tags->getTagkey();
    $this->view->Tagkey = $aResultData;
    $form = new Admin_Form_Users($aResultData);
    if ($this->getRequest()->isPost()) {
        if ($form->isValid($this->getRequest()->getPost())) {
            // valid
        } else { 
            // errors 
        }
    }
}

然后在表单中添加一个构造函数。

// Admin_Form_Model
public function __construct($tagKey)
{   
    $this->tagKey = $tagKey;
    parent::__construct(); // you must call this last as it calls init()
}

您的问题是一个简单的错误：

您设置了变量$childs = array();
然后称其为$children：

foreach ($children as $child) {
           $subForm->addElement($child);
       }

这可能不是这个脚本中唯一的错误，但它是消息处理的错误。
