I have a form, and I want to pass it one parameter which must use to fill a widget.
I pass the parameter in my url :
url_for('myModule/new?parameter='.$myParam)
I have tried to take the parameter in my action and display it in my tamplate, but it doesn't work.
Action :
$this->param = $request->getParameter('parameter');
Template :
echo param;
But I can't recover it in my form.
How can I do this ?
If this parameter is needed for initializing your form then you could do it like this (keep in mind that you should always validate user input)
public function executeNew($request)
{
$formOptions = array('parameter' => $request->getParameter('parameter'));
$this->form = new MyForm(array(), $formOptions);
// Then within your form you access it with:
// $parameter = $this->options['parameter'];
// or even better:
// $parameter = $this->getOption('parameter');
... more code ...
}
If the parameter is submitted as part of the form then you should bind it like this:
public function executeNew($request)
{
$this->form = new MyForm();
if ( $request->isMethod('post') ) {
$this->form->bind($request->getPostParameters());
}
... more code ...
}
Please refer to the Symfony's Forms in Action for more on how to create and use forms.
Edit: Added $this->getOption('parameter') to the code example.
$this->getOption('parameter') and didn't work. Looks like the right way to do it is get it from the Form instance like this: $this->form->getOption('parameter')you have to define a route for this URL in your routing.yml and add your parameter to this route.
for example:
mymoduel_new:
url: myModule/new/:paramter/
param: { module: myModule, action: new }
You need to pass it to the form constructor, both the constructors of sfForm and sf{Propel,Doctrine}Form take a parameter called $options, use that. Store the value in a private property, so you can use in in the form's configure method.
If the parameter is an attribute of the object, you can do :
$object = new Class();
$object->setAttribute($request->getParameter('myParam'));
$form = new ClassForm($object);
$form = new ClassForm($object, array("myoption" => $request->getParameter("myOption")));
