php - Custom Form Handling in Wordpress and GAE -

I am trying to impliment a custom form in a WordPress page, I have set up the form and in this way :

  & lt; Form method = "POST" action = "/ handleForm.php" & gt; & Lt; Input type = "text" name = "userName" /> & Lt; Input type = "submit" / & gt; & Lt; / Form & gt;  

handleForm.php:

  resonance ($ _ POST ['username']); Echo ('fire');  

app.yaml (except for the default Wordpress stuff):

  - url: /handleform.php script: handleForm.php  < / Pre> 
  handleForm.php  file  app.yaml  is in the root folder next to the file. 
 
 When I submit the form, it goes to the correct URL, but nothing happens ... I have it at least  fire  on  echo  I hope Is there any information about what is happening here? Do I remember something about  Wordpress  or  GAE  
 

additional .php should be in the root / wordpress folder and prefixed with wp - . For example:

  root / wordpress / wp-handleForm.php  

then verb {/ code> attribute tag of the form to / code> /wp-handleform.php .

 should be set as
