Create a form for uploading images - forms

Question

I want to let users upload images from their drives. Searching around the net, here's what I've found :
The form :
class ImageForm extends BaseForm
{
public function configure()
{
parent::setUp();
$this->setWidget('file', new sfWidgetFormInputFileEditable(
array(
'edit_mode'=>false,
'with_delete' => false,
'file_src' => '',
)
));
$this->setValidator('file', new sfValidatorFile(
array(
'max_size' => 500000,
'mime_types' => 'web_images',
'path' => '/web/uploads/assets',
'required' => true
//'validated_file_class' => 'sfValidatedFileCustom'
)
));
}
}
the action :
public function executeAdd(sfWebRequest $request)
{
$this->form = new ImageForm();
if ($request->isMethod('post'))
if ($this->form->isValid())
{
//...what goes here ?
}
}
the template :
<form action="<?php echo url_for('#images_add') ?>" method="POST" enctype="multipart/data">
<?php echo $form['file']->renderError() ?>
<?php echo $form->render(array('file' => array('class' => 'file'))) ?>
<input type="submit" value="envoyer" />
</form>
Symfony doesn't throw any errors, but nothing is transfered. What am I missing ?

Answer 1

Youre missing an impotant part which is binding the the values to the form:
public function executeAdd(sfWebRequest $request)
{
$this->form = new ImageForm();
if ($request->isMethod('post'))
{
// you need to bind the values and files to the submitted form
$this->form->bind(
$request->getParameter($this->form->getName())
$request->getFiles($this->form->getName())
);
// then check if its valid - if it is valid the validator
// should save the file for you
if ($this->form->isValid())
{
// redirect, render a different view, or set a flash message
}
}
}
However, you want to make sure you set the name format for your form so you can grab a the values and files in the fashion... In your configure method you need to call setNameFormat:
public function configure()
{
// other config code
$this->widgetSchema->setNameFormat('image[%s]');
}
Also in configure you dont need to call parent::setUp()... That is called automatically and is actually what invokes the configure method.
LAstly, you ned to have to correct markup - your emissing the form name from your tag:
<form action="<?php echo url_for('#images_add') ?>" name="<?php echo $form->getName() ?>" method="POST" enctype="multipart/data">
Personally I like to use the form object to generate this as well as it looks cleaner to my eyes:
<?php echo $form->renderFormTag(
url_for('#images_add'),
array('method' => 'post') // any other html attriubutes
) ?>
It will work out the encoding and name attributes based on how youve configured the form.
