如何在ZF1项目的视图中呈现ZF2表单

Question

I am trying to use ZF2 classes in ZF1 project. I have been following this link: Use ZF2 in a ZF1 project . I can use ZF2 classes to create model, table model by inheriting AbstractTableGateway.

I am getting objects on controller. But when I tries to render those form object on view (phtml). It is throwing error, like this:

Fatal error: Call to undefined method Zend\Form\Form::openTag() in /var/www/myproject/application/modules/tools/views/scripts/tablesample/add.phtml on line 14

Here is the view file:

<?php
use Zend\Form\Form as Form;
$baseUrl = $this->baseUrl();
$formObject = new Form();
// this is demo  print block of form element
$form = $this->form;
$form->setAttribute('action', $baseUrl.'tools/tablesample/add');
$form->prepare();

echo $formObject->openTag($form);
echo $this->formRow($form->get('name'));
echo $this->formRow($form->get('gender'));
echo $this->formRow($form->get('hobby'));
echo $this->formRow($form->get('email'));
echo $this->formRow($form->get('birth'));
echo $this->formRow($form->get('address'));
echo $this->formRow($form->get('direction'));
echo $this->form()->closeTag();

?>

I think ZF1 is not detecting ZF2's form helper or there may be any other way to use ZF2 form helper in ZF1 project.

How can I properly render my ZF2 forms in ZF1 application?

I am following this tutorial to create forms: Zend Framework 2 : Extending Zend\\Form to add Select, Multicheckbox, Email,Date, Textarea, and Radio element

I just need to confirm whether I can use ZF2 forms in ZF1 project or not. If it can be used then please show me the view file for this tutorial.

While I personally can't offer any advise in integrating ZF2 into ZF1; From the ZF2 side of things, the error you are receiving is due to this line :

$formObject->openTag($form);

You are trying to use the form object Zend\\Form\\Form to render the open tag of the form. Instead you need to be using the form view helper ( Zend\\Form\\View\\Helper\\Form ) and then pass in the form ( $form ) as an argument.

For example

$this->form()->openTag($form);

You are actually doing it right for the forms closing tag (which doesn't need any arguments):

echo $this->form()->closeTag();

Also, I'm unsure of your purpose for $formObject = new Form() ; there is not need for a new form instance in the code you posted (and you shouldn't really create new instances in the view like this anyway).

The $this->form() will be caught by the magic __call() of the renderer; which will then check if there is a view helper registered with the service name form (returning it when its found).

All the view helpers work in this manor. They are objects that introspect the arguments provided to them and render the appropriate HTML.

With the $this->form() for instance, is used to render the form open tags. Another example could be the URL helper ( $this->url('route') ) which would generate a URL form the provided arguments.

I would recommend reading up on the view helper documentation and take a good look at the source code for the already built in view helpers as this will give you a good idea on how they all work.
