Re: This is weird, this script does/doesn't work

on my own machine, W2k+Apache+php4.2 this works without problem, on the Internet-server though, (Linux), the following script produces a blank page: <?php require "../utils.php"; $link=openDB(); $file = $target.form; // Queries for student if ($target == "student") { // Add student <Query to add> // Change student info <Query to change info> // Delete student <Query to delete> } // Queries for result if ($target == "result") { // Delete result <Query to delete> } if(!isset($administrate) && $goal) { if ($logga_in == "ok" ) { $adm_user = "admin"; $adm_pass = "password"; if ($operation == "logon") { if ($password == $adm_pass && $admin == $adm_user) { setcookie("administrate", "OK", 0); include("../recycle/head.php"); include ("$file.php"); } else { include("../recycle/head.php"); echo "<CENTER><FONT SIZE=\"5\" COLOR=\"#C90000\">Please try again. Check your spelling.</FONT><CENTER>"; include ("loginform.php"); } } } else { include("../recycle/head.php"); include ("loginform.php"); } } elseif ($target) {//When logged in this load the right form include("../recycle/head.php"); include ("$file.php"); } if (!$target) {//This happens when first loaded. In the head.php there's a menu and the different targets are set include("../recycle/head.php"); echo " <H2>Administration of <SUB><IMG BORDER=0 SRC=\"../pics/mypicmin.gif\" WIDTH=135 HEIGHT=30></SUB></H2> "; } include("../recycle/bottom.php"); ?> Explanation: utils.php with the two functions openDB() and queryDB() connect to the database and do the query. loginform.php contains the html to the loginform. $file = $target.form; so the right form will be loaded. So, what is wrong, why does it 'behave' so different? Does not look that there are any problems in your script. The real problem could be in the include files though!

You might start doing the following 1) check if your internet server allows access to the other directories (like ../recycle and ../). I suppose that you did not forget to copy these files too ;-) 2) compare the php.ini of your test system and the internet server. Differences might give a clue to the problem 3) view the source code of the 'blank page' . Is it realy blank? It might contain a bit of HTML output that can give a hint of were your script stops 4) include error_reporting(E_ALL); as first line of code in your php-scripts. It might help debugging 5) does your internet server have access to the database? Is it the same database? Arre the access rights the same? 6) run this script on both machines and look for differences in the outputs:

       <?php php_info() ?>

Good luck René
