Some php help with this ad rotator wp plugin..

I'm trying to get the ad rotator wp plugin to work by the line order instead of it being random.. can any php expert help me out?

here is the orignal code

<?php
function getad($ad = '') {
  $ad = trim($ad);
  if(strlen($ad) > 0) {
    $ad = ABSPATH . "wp-content/" . $ad . '.txt';
    if(file_exists($ad)) {
      $ads = file($ad);
      return $ads[rand(0, sizeof($ads)-1)];
    }
  }
}
?>

PHP:

and this is the modfied one but it dosen't move onto the next line..

<?php
function getad($ad = '') {
  $ad = trim($ad);
  if(strlen($ad) > 0) {
    $ad = ABSPATH . "wp-content/" . $ad . '.txt';
    if(file_exists($ad)) {
      $ads = file($ad);
      //$adscnt = count($ads);
      foreach($ads as $linenum => $line) {
			return $line;
		}
    }
  }
}
?>

PHP:

I'm sure it's something simple but no idea since I'm clueless when it comes to php.

appreciate any help with this.

 

try

<?php
$_SESSION['current_ad'] = 0;
function getad($ad = '') {
  $ad = trim($ad);
  if(strlen($ad) > 0) {
    $ad = ABSPATH . "wp-content/" . $ad . '.txt';
    if(file_exists($ad)) {
      $ads = file($ad);
      $i = $_SESSION['current_ad'];
      $_SESSION['current_ad']++;
      return $ads[$i];
    }
  }
}
?>

PHP:

However, you must have sessions enabled in your code.

 

Thnaks for the help but where will i need to add the session in my code?

 

just try the code I given first.

If you see any errors regarding session, you will have to add

session_start();

PHP:

at the very top of your page (ie. header), after the <?php.

 

I tried the code and it stopped displaying the html codes in the text file all together.. any ideas?

 

well, forget about the sessions.
now try these codes:

<?php
$_COOKIE['current_ad'] = 0;
function getad($ad = '') {
  $ad = trim($ad);
  if(strlen($ad) > 0) {
    $ad = ABSPATH . "wp-content/" . $ad . '.txt';
    if(file_exists($ad)) {
      $ads = file($ad);
      $i = $_COOKIE['current_ad'];
      $_COOKIE['current_ad']++;
      return $ads[$i];
    }
  }
}
?>

PHP:

don't forget to remove the session_start(); to avoid whitescreen

 

the 2nd code loads only the first line with out rotating to the other lines..

Thanks I Appreciate your help.
