hi . am editting a code i have on a gallery script. so its has a download function for users and also a hits counter.

my hits counter and downloading code works perfect but am struggling with the while loop and how to get it so the link shows under each picture .

At present its showing the first picture then the download links for all 5 pictures that is displaying.

quick  pictorial example below as to what the output is .

[] <<< pic 1

link for pic 1

link for pic 2

link for pic 3

link for pic 4

link for pic 5

[] <<< pic 2

[] <<< pic 3

[] <<< pic 4

[] <<< pic 5

Thats what the page looks like . I do like to try to give you guys as much info as possible lol

 

if($action=="males")
{
  addonline(getuid_sid($sid),"Male Gallery","");
echo "<head>";
echo "<title>Gallery Pics</title>";

The issue seems to be caused by the double-query / double-loop thing you have going on. First you have the $sql variable which is being processed twice:

 

<?php
$sql = "SELECT uid, id, imageurl FROM dave_usergallery WHERE sex='M' ORDER BY id DESC LIMIT $limit_start, $items_per_page";
//...
$result = mysql_query($sql) or die("Error: " . mysql_error()); 
//...
$items = mysql_query($sql);
?>

 

 

Then you have two while loops, one to process $items and the other to process $result. The code should work fine if you just remove the second while loop. Try changing this:

 

<?php
echo "</small><br/><a href=\"$item[2]\" alt=\"$userinfo[0]\"/>Download<br/>";
while($row = mysql_fetch_array($result)){
     echo "<br/><a href=\"getpics.php?file=$row[id]&sid=$sid\">Download test</a>";
     echo "<br/>";
}
echo "</small><br/><br/>";
?>

 

 

To this (note that I changed $row to $item):

 

<?php
echo "</small><br/><a href=\"$item[2]\" alt=\"$userinfo[0]\"/>Download<br/>";
echo "<br/><a href=\"getpics.php?file=$item[id]&sid=$sid\">Download test</a>";
echo "<br/>";
echo "</small><br/><br/>";
?>

firstly thanks for your informative help.  posted this on 2 other forums also and just got negative comments. so thanks .

 

and secondly i resolved the problem without even using a loop. and i also changed $row to $item .

 

 

No problem, I totally understand the frustration of only receiving negative comments. Glad to hear that the issue was resolved. 8)
