I need help with a dynamic link on my web page. This is a site where accommodation establishments register their details and upload a photo.

Here is the problem I have:
I have a page listing all users (user_list.php) where I retrieve details (acc_name, address, photo) of registered users from mysql database. I also have a dynamic link to a page (profile.php) where details of user is listed with a photo.

Everything works fine but when I click the link (first click on link) to the specific users details (profile.php) it displays fine. However, when I go back to my user list (user_list.php) and click the link of another registered user (profile.php) the profile of the previous user are redisplayed. I have reset/cleared all my browsing history but still have the same problem. Below is the code for the link to profile.php in my user_list php page.

<td class='tduser' width=15% align='center' valign='middle'><a href='profile.php?id=".$row['id']."'>".$row['acc_name']."</td>

I am querying the database correctly? Please provide me with a solution to this problem. I am missing something and cannot get around to solving it.
Below find the full code for my user_list.php.

<?php
include 'dbc.php';
include 'includes/title.inc.php';
page_protect();
$member = @$_GET['member'];
/******************** ADD ME TO SHOW USERS AVATAR ****************************/
$img_url_query = mysql_query("select avatar_url from users where id = '$_SESSION[user_id]'");
while($img_url_settings = mysql_fetch_array($img_url_query)) {
$img_url = $img_url_settings['avatar_url'];
}

... where id = '$_SESSION[user_id]'") are you updating $_SESSION[user_id] to that of the one you selected/click on in profile.php?

No. I am not updating specfic user details. The link to profile.php will get the current saved details from database of user. User details get displayed when i click link. The problem is that the same user details show when click on link for different users in my user_list.php page. E.G: The profile for user1 gets display for user2 when i click link for profile of user2. The same for others when i click their links to view their profiles. User1 profile keeps getting displayed.

currently in user_list.php (line 95) you have SELECT * FROM users LIMIT $startrow, 10 . If in fact your users table has a field named `id`, then focus your efforts in profile.php since user_list.php seems fine. In profile.php you should be retrieving the user id by issuing $_GET['id'] NOT $_POST['id']

hielo. can you provide an example or link to a tutorial.

can you post your code to profile.php?

Hielo, Herewith my code for my profile.php page. Once again thank you for taking the time to look at this problem for me.

<?php
include 'dbc.php';
include 'includes/title.inc.php';
page_protect();

//retrieve the user's info
$q = "SELECT * FROM users where id='$_SESSION[user_id]'" ;
$res_q = mysql_query($q);
if(!$res_q){
echo mysql_error();
}else{
$row = mysql_fetch_assoc($res_q);
}
?>

instead of: $q = "SELECT * FROM users where id='$_SESSION[user_id]'" ; try: $q = sprintf("SELECT * FROM users where id='%s' LIMIT 1", mysql_real_escape_string($_GET['id']) ;

hielo. i tried your suggestion but i get a pass error. any reason why?

i get a pass error

Is this error reported by your server or is it some editor that you are using?

On another note, I missed closing parenthesis at the end of that line:

$q = sprintf("SELECT * FROM users where id='%s' LIMIT 1", mysql_real_escape_string($_GET['id']) ) ;

Hielo, apologies for late reply. Your suggestions worked for dynamic link problem i had. Appreciate your help. Will mark this post as solved. Thanks

You are welcome.

Hielo
