在第二页上无法识别表格发布

Question

I have a very very basic dilemma that i am struggling with @ the moment. I have a Symfony form that posts to another page, essentially user is redirected to template_2 and the form exists on template_1. This I achieve like this:

renderFormTag('module/template2');

In the action of template_2, I have the following code:

if($request->isMethod('post'))
{
  // retrieve form values from the Form available in template 1 
   $params = $this->getRequestParameter('formFieldName');
   echo $params; 

}

However, this isn't happening.

Nothing is being echoed out. I put in an echo "hello" but that does not execute either. Infact I put in an echo "hello" outside of the if condition and that does not echo either.

I doublechecked the name of the template and the action , and that part is good.

Can anybody tell me where I am messing up?

Check the generated HTML whether it is valid or not and then check if the url in form tag is present in the output of symfony app:routes your_application_name and if it's accept a POST request and you can check if the right route matched in the dev toolbar.

If it's a symfony generated form, I think $this->getRequestParameter('formFieldName'); is wrong, because fields in generated form usually encapsulated into an array of the form name... so you should write $this->getRequestParameter('form_name[form_field_name]'); see the HTML or the base form class for the form name. But be aware if you accessing posted values this way (from the request) they'll never be validated , it would be batter to recreate the form, validate the submitted data and access them through the form, see an example here ( executeCreate and processForm methods in the action class).
