# Integrating WordPress with a Codeigniter app using $_POST variables

 * [10 years, 1 month ago](https://wordpress.org/support/topic/integrating-wordpress-with-a-codeigniter-app-using-_post-variables/)
 * I’m writing a plugin to register and login to a codeigniter app we’ve got at 
   the same time as registering and logging in to wordpress. the solution I came
   up with is to submit the form variables to the codeigniter login controller function“
   check_login” and after it confirms login on the codeigniter side it starts a 
   session and populates some session variables before redirecting back to a worpress
   page. The session variables are then captured by a plugin function hooked into“
   wp_head” that logs them into wordpress and then unsets the variables.
 * The problem I’m having is when I hit submit and it sends the form $_POST variables
   to “check_login” the variables don’t come through. I added:
 *     ```
       var_dump($_REQUEST);
       		exit();
       ```
   
 * And nothing is being sent over. The plugin code is as follows:
 *     ```

 * And below is the login controller of the codeigniter app. I can provide the registration
   code as well but I think I will solve both problems if I figure out one. When
   I started writing the plugin I did the login first, and it worked for a bit, 
   until I started writing the registration portion.

 * I need some more eyes on this. It is getting incredibly frustrating. Currently
   the htaccess file in the base folder contains the standard WordPress rewrite 
   rule. I can include the validate_user_login function as well, but I don’t think
   there is anything making it that far. Is WordPress somehow blocking the $_POST
   variables?
 * EDIT- I just talked to our hosting provider and they passed me these errors:
