Question

I’m not good with PHP, so please bear with me. I have the following code:

<?php $thisPage="designers";
include("phpincludes/header.php") ?>

<div id="contentLeft">
<?echo "<h2><a href='designer_display.php?d_name=".$_GET['d_name']."'>" . $_GET['d_name']. "</a></h2>";?>

<?
    error_reporting(0);
    require_once "phpincludes/connection.php";

    $designer = $_GET['d_name'];
    // Category Selection Start.
    $cat_qry = "SELECT DISTINCT (
        `own_category`
    )
    FROM  `products` 
    WHERE  `designer` ='".$designer."' && own_category !=  ''";
        $rs_qry = mysql_query($cat_qry);

            $i = 0;

        while($rec_qry = mysql_fetch_array($rs_qry))
        {
          if($i==0)
            $first_cat = $rec_qry['cat_name'];
            $cat_name[$i]=$rec_qry['cat_name'];
            $i++;
        }

        // Category Selection Start.
        $cat_name = $_GET['catName1'];
        $cat_qry =  "SELECT DISTINCT (
        `own_category`

            $rs_qry = mysql_query($cat_qry);
            $rec_no = mysql_affected_rows();

            /*if($_GET["catName1"]=="")
                $catName = $first_cat;

<?php include("phpincludes/base.php") ?>

Much of the code was written by someone else, but I’ve been modifying it in a couple of ways. It works locally (on XAMP) and on my personal site where I’ve been hosting it as a test site.

But when i uploaded it to the client’s host, this page stops abruptly at echo "<ul class=\"items\">"; – roughly line 73. I can’t see what’s stopping it from running properly.

Some assistance would be gratefully received!

Answer 1

That’s hard to tell. It’s very obviously something with the clients setup.

Taking a wild guess, that client is still running PHP4. Because after line 73 you have a call to str_ireplace which wasn’t available for that.

You would likely get a fatal error for this one. And this is the right avenue for investigation here. Add this on top for debugging (instead of error_reporting(0) which is not so helpful):

error_reporting(E_ALL|E_WARNING);

And ask for errors. Better yet, provide a custom error handler which prints out something shiny for end user-type clients. Otherwise ask for the error.log which should contain the exact error likewise.
