[SOLVED] if password is incorrect, how do i redirect back to login/register?

[frijole]

i am trying to find a way to check if the password matches the saved one, or the second one in the register form, and if not echo that it is incorrect and show the form again for them to re-enter.

First of all, there are a hundred different ways to do this. A quick way would be to create a validation function in php and compare the two values.  If they don't match redirect to the registration page while triggering an error through a get variable.

 

Example:

<?php
// validation function, assuming you've already submitted the form grabbed the $_POST variables and send the variables to the validation function
function validate($pass1,$pass2){
  if($pass1 != $pass2){
     header("Location: login.php?error=1");
  }
}
?>

 

On the login page run a check for errors in the url.

 

<?php
if(isset($_GET['error'])){
if($error == 1){
   echo "The password fields don't match!";
}
}
?>

on my registration i have...

 

<?php

  $password = $_POST['password'];
  $confirmpw = $_POST['confirmpw'];

  if($confirmpw != $password) {
    echo "Your passwords did not match. Please try again<BR />";
    echo "Redirecting...";
    echo "<meta http-equiv='refresh' content='3;url=index.php?action=register' />";
    exit();
  }
?>

If i want to use functions how do I attach them to the page? Should I simply make a functions.php and attatch it to all the registration page?

 

include functions.php?

That would work
