Variable in url via echo

[mattgnr]

Hi,

I am trying to use the SID tracking via Commission Junction to create a reward site.

An example code banner display is:

<a href="http://www.jdoqocy.com/click-4011209-10677311?sid=$userid " target="_blank">
<img src="http://www.lduhtrp.net/image-4011209-10677311" width="468" height="60" alt="Extend the life of your PC - Optimize your Slow PC" border="0"/></a>

This is stored in my database which i then echo onto the page.

I have decided $userid and this has already been called. However the url is not picking this up and instead just displays $userid rather than the number.

Has anyone any suggestions?

Many thanks!

I can not be sure this is gonna work because you gave only small sample of your code but here it is:

<a href="http://www.jdoqocy.com/click-4011209-10677311?sid=<?php echo $userid;?> " target="_blank">

Hi,

Thanks - i'm not sure thats going to work as i can't call a php echo inside an echo can I?

The code displayed on the page is simply:

<?php 
$userid = 1;
echo $row_Offers['html']; ?>

what is output when you echo $row_Offers['html']

The original code I had in the first box:

   1. <a href="http://www.jdoqocy.com/click-4011209-10677311?sid=$userid " target="_blank">
   2. <img src="http://www.lduhtrp.net/image-4011209-10677311" width="468" height="60" alt="Extend the life of your PC - Optimize your Slow PC" border="0"/></a>

However the actual output on preview is the banner linking through to the url but instead of sid=1, it shows sid=$userid

Hm... so $row_Offers['html'] is puled from database? Why don't you simply change your <....?sid=$user id....> to <....?sid=1.... > in database?

Because the $userid is constantly being changed dependant on who log's in. (1 was just an example, $userid is actually pulled from a different table in the database). It's a rewards site so i need to be able to track the SID's in the links.

Thanks!

I see. In that case you will find useful str_replace function. Variables do not just jump into the string. You need to place them there. The str_replace is your solution.
