Hello all
,
i'm trying to create a form with file upload using the Zend_Form component using ZF version 1.5.1.
I created the
Zend_Form_Element_File component which, for some reason, was missing (while
Zend_Form_Element_File exists...)
Here's my Zend/Form/Element/File.php :
PHP Code:
require_once 'Zend/Form/Element/Xhtml.php';
class Zend_Form_Element_File extends Zend_Form_Element_Xhtml
{
public $helper = 'formFile';
}
And this is my controller action:
PHP Code:
function testAction()
{
$form = new Zend_Form();
$form->setAction('/this/test')
->setMethod('post');
$file = $form->createElement('file', 'file');
$form->addElement($file)
->addElement('submit', 'upload', array('label' => 'Upload File'));
// Just to test if the file has really been processed...
if ($this->getRequest()->isPost())
{
Zend_Debug::dump($_FILES);
exit;
}
$this->view->form = $form;
echo $this->view->render('testform.tpl');
}
This code will produce a small form with only one file upload field and the submit button, so it's really simple.
My problem is that i can't figure out some things:
1. How to set custom form enctype?
To handle file uploads i need to set it to 'multipart/form-data'. But i can't find anything to do such thing.. The only thing i know is that i should set some option(s) on the form decorator.
2. How to let Zend_Form to see file fields during form validation?
As seen on the ZF programming reference manual, the form is validated using:
PHP Code:
if ($form->isValid($_POST)) {
// success!
} else {
// failure!
}
Since php handles files upload using $_FILES superglobal array, maybe i could make some (dirty) thing like:
PHP Code:
$myPost = array_merge($_POST, $_FILES);
if ($form->isValid($myPost)) {
// Processing form data ...
}
Could this be the quick&dirty solution ??
3. How to write validators for file fields ?
Maybe the method described in
this post could be suitable for my needs..?
I tried to explain the thing as best as i could.
I'm not a native english-speaker, so please forgive me if i misspelled something.
Any help is appreciated.
Thank you all.
