How to create a form in zend

Question

I am following this thread to create a form and it is working when No. of form elements are known. Now I have to create form fields based on user choice.

For Example:

<?php class Form_MyForm extends Zend_Form { public function __construct( $options = null ) { parent::__construct( $options ); // Set the method for the display form to POST $this->setMethod('post'); $elements = array(); // Get user input to create elements $fields = $options['columns']; // Create form elements for( $i = 0; $i < count( $fields ); $i++ ) { $element = $this->CreateElement('text', 'field'.$i ); $element->setLabel( $fields[$i]['name'] ); $elements[] = $element; } $this->addElements( $elements ); $this->setElementDecorators( array( 'ViewHelper' ) ); $this->setDecorators( array( array( 'ViewScript', array( 'viewScript' => 'myform-form.phtml' ) ) ) ); } // end construct } // end class ?>

I can render each element separately but Now I don't know how to render these elements in myform-form.phtml by looping. I have to loop because No. Fields are not known at the begining..

Thanks

I'm not exactly a Zend_Form wiz (I actually hate it), but maybe you should move your code into another method (say configureForm() and have it accept an argument with the number of fields instead? — netcoder

What is your $columns variable? I don't see where it is created. — Marcin

@Marcin: Sorry it was typo. It is actually $field array. It contains Labels of form fields. For Example: array('FirstName','LastName','BirthDate'); Please review the question again. Thanks — Student

should use something like this (didn't test it)

<? foreach ($this->element->getElements() as $element){ echo $this->{$element->helper}( $element->getName(), 1, $element->getAttribs() ) } ?>

$this->element should be your form

Side note to start: It's typical to do all this in the init() method rather than overriding the form constructor. But that's not really a big deal.

Re: rendering of the fields using the view script of ViewScript decorator: In myform-form.phtml, seems like you could call $this->getOption('columns') and then perform a foreach loop to render the elements, analogous to the loop you used to create the fields.
