Form Validation: Custom Callback Rule Problem... |
Hey--I've set up a custom Form Validation Callback fairly similar to the "username" example shown in the Manual.
Everything seems to be working great except when I load the page(this is the 2nd page of the form) I have the Error message come up on the First attempt. Why is this happening and what can I do to avoid this? Code for setting callback up: $this->form_validation->set_rules ('header_1', 'Header 1', 'callback_bigsearch_check'); Callback Function: function bigsearch_check($header_1) { $query_example = $this->db->query(" SELECT * FROM Table WHERE Header = '$header_1' "); if($query_example->num_rows() == 0) { $this->form_validation->set_message( 'bigsearch_check', 'That Item is not Found in the Database, Please Select One from the dropdown' ); return FALSE; } else { return TRUE; } } Callback function ~Ryan
You are doing something wrong with the run() method.
PHP Code: if( $this->form_validation->run() === TRUE ) You also got a SQL Injection in your code. Use Query binding. https://www.codeigniter.com/user_guide/d...y-bindings
You mention that this is the 2nd page of your form. I guess the form_validation rule is applied after you post the 1st page.
Please, share the logic in your controller that handles the form pages and $_POST result. And please, don't paste your php code as plain text in the forum editor. There's a button for php code in the button bar. If you use that, you make the code much better readable for everyone. |
