passing a variable back to a function

[eluser]Unknown[/eluser]
Hello,

my question is, if I have a function called test1() and this function is called in my controller:

Code:

$this->test1();

but I also wish a function called test2 to pass a variable to it later in the code.

Code:

public function test2(){
   $passed='foo';
   return $passed;
}

$this->test1($passed);

My program throws an error because $passed is not needed the first time. Do I need to override test with another implementation. How would I do this.

Sorry if this is a basic question. Any help or advice would be greatly appreciated.

Thanks

PTVW

Your example code doesn't match up with my understanding of what you said you're trying to do. That aside, you can give test1 a parameter with a default value so that it works regardless of if you pass a value to it or not.

Code:

function test1($param = null) {
    // Function code goes here
}

Thanks for replying, but wouldn't that always set the value to null when its passed too?

Those weren't actual extracts from the application but I didn't illustrate very well. I thought I would need to override.

It will only be null if you don't pass a value for the variable. Check the php manual at http://www.php.net/manual/en/functions.a...ts.default for more information.

Code:

class Blah extends CI_Controller(){
  
   public $pass_me_around;

   public function test1(){
      $this->pass_me_around = 'Wow, i can be globally used in this class after i am set, how cool is $this ?';
   }

   public function test2(){
       return $this->pass_me_around ;
   }


}
