Search Criteria Ignored, Only Redirects to Else Statement

If that's the case your problem are here "$this->input->post('submit')", that it gets validated as false.
Just do a double check and add die('Hello'); the first thing inside that if statement.

PHP Code:

function search(){
 if($this->input->post('submit')){
   die('Hello');
...
  }
} 


If you don't see "Hello"; Add var_dump($this->input->post('submit'));exit; before that if and see what you are getting.

ALSO: Your search() code have SQL injections. You should fix that ASAP!

Thank you for your help! That did not work unfortunately.

Nothing happened after this. It returned the same recipe page.

I got the following error after the above code:

Code:

An uncaught Exception was encountered

Type: ParseError

Message: syntax error, unexpected 'var_dump' (T_STRING), expecting '('

Filename: /home/www/shirleysrecipes.100webspace.net/application/controllers/Recipe.php

Line Number: 52

Backtrace:

Line 54 is the var dump line?

Weird.

Thank you again!
