You can recall/use a value within a method using $this like so...

<?php

function myMethod($var) {
  return $this->value.$var;
}

?>

You can't use $this outside of your method/class.

wildteen88 · November 9, 2008

$this can only be used within an object. It cannot be used outside of it.

The following portion of code is incorrect

$this->min_pass_length=8;
   $this->max_pass_length=12;
   $this->chars='abcdefghijklmnopqrstuvwxyz0123456789';

What are you trying to do here?

Caesar · November 9, 2008

Did you take that code from somewhere? If so, it was probably inside a class.

.josh · November 9, 2008

(others posted while I was typing...hopefully this will further clarify)

example:

<?php
class something {

   var $blah;

   function dosomething () {
      // works
      $this->blah = "foobar";
   } 
}

// will not work
$this->blah = "foobar";

"$this->" means assign foobar to the variable "blah" in "this" class (something).

if you use it outside the class...you'd be assigning foobar to "this" ...what? In other words, "$this->blah" is an alias for a class name. You can only use it inside a class, because otherwise, it would be ambiguous.

What im trying to do there, is to Make a Password in Minimum length 8 and maximum length 12 + allowed chars as you see.. but i dont know how to do it in another way.

If it is someone that could help me remake that code, soo please i would appreciate that!

This is in a include folder and are include with all the scripts.. so were ever i go on the site i get the same error.. so its needed to work perfectly.

I just search for any instance of min_pass_length, max_pass_length and chars and nothing was found. it appears these are not needed for the script to work and do not have any relevance.

Okey, But if i want it to be in a minimum/maximum length, How do i fix that then?

Thanks for help, I Really appreciate it!

But assuming that they were to be found, and assuming that they were marked as public (can be used outside the class), you would use objectname->property.

Going back to my example:

<?php
class something {

   var $blah;
   private $awsd;

   function dosomething () {
      // works
      $this->blah = "foobar";
   } 
}

// create an instance of the class (object)
$someobject = new something();

// will not work because it is outside of the class
$this->blah = "foobar";

// this will work, because blah is public
$someobject->blah = "foobar";
// will not work, because it's private
$someobject->aswd = "laksdjf";
?>

Well you are going to have to add them into your class or wherever, and add it to your form validation. We aren't really here to pick apart some 3rd party code and figure that out for you. I suggest contacting the person who wrote the script, or else picking up a book and starting with the basics. Or like, hiring someone.

Okey, Thanks all for the Help, The site is working!
