Linking System

Hi all,

Using PHP, I would like to create a similar linking system to the one used on this site. So each link is entered into a database, given an id, and linked to like "out.php?id=4" or something.

I haven't used MySQL for ages, so I'm not completely sure how to do it. I think it would involve a for statement with mysql_num_rows, something like:

PHP Code:

---

$result = mysql_query("SELECT * FROM table", $dbcnx) ;

for ($x= 0; $x < mysql_num_rows($result); $x++)
{
    $row = mysql_fetch_assoc($result) ;

    echo ("<a href=\"out.php?id=") ;
    echo ($row['ID']) ;
    echo ("\">") ; 


---

As I said, it's a long time since I last used MySQL and PHP together, so chances are that's probably wrong.

Please could anyone give me any advice on an easier way or anything?

Thanks a lot,
Mike

I'm not sure exactly what you're trying to do. Your code will produce a list of href tags. 1 for each table row.

If you're after the code for the "out.php" script, it would be something like:

PHP Code:

---


$sql = "SELECT url FROM links_table WHERE id = '$id'";
$result = mysql_query($sql, $db);

if($result) { 
   $url = mysql_result($result, 0);
   header("location: $url");
} else {
   echo "ID not found";
}

Or something like that anyway.

Yeh, I see what you mean. I got it from another script I did sometime last year.

Anyway, I will have another bash with your idea...

Thanks a lot,

By the way, does the header() function work in all browsers?

Thanks,

yes

Thanks:)

Just to let everyone know, I got it sorted through chromate's code...

Thanks chromate:)

no probs
