Thats a good question.
The simple answer is to have the data in hidden fields in the page. I guess you could store the data in a namespace with a unique ID, that ID would be sent back in with the POST or GET to retrieve the data for further editing.

That's a good point, I didn't take into account. The main point using the session was to store form data in case that we have a preview action. In this case form data is no longer in the post array. What would be in your opinion the best way to store data in this case? Thanks. Best regards, Ivan.

Check out this tutorial: http://akrabat.com/zend-framework-tutorial/ It has a really good example application for forms.

I serialize the post array an keep it in an own session namespace. Additionally, I pass the form data array to the view in the controller action, so that the view does not need to know about the existence of sessions. Take a look at the sample code below. If everyone has a better idea, I would be happy to know! Best regards, Ivan. /* Display form */ public function displayformAction() { $this->initView(); // Check session for form data $formSession = new Zend_Session_Namespace('form'); if (isset($formSession->formData)) { $formData = unserialize($formSession->formData); $this->view->formData = $formData; } /* Render form */ } /* Check user input */ public function checkformAction() { // Get POST data $request = $this->getRequest(); $post = $request->getPost(); /* Validation logic */ /* If errors, go back to view */ // Pass error message... $this->view->formData = $post; // Redirect /* If input ok */ $formSession = new Zend_Session_Namespace('form'); $formSession->formData = serialize($post); // Go to previewAction, e.g. } Hi All I have developed a form using zend framework.When i click on submit button and id if due to validation some error message is displayed , at that time the values entered in text box will not be retained. Is their any way to retain these values using zend functionality Regard, Rohit83 -- Loglan GmbH Ivan Ruiz Gallego Binzmühlestrasse 210 8050 Zürich Switzerland Office +41 44 310 19 20 Mobile +41 76 321 23 68 Net www.loglan.net
