[SOLVED] Changing Links

[herghost]

Hi all, I am slowly picking up php and am getting there! Thanks to all those who have helped me so far! I have a quick question, I shall try and explain it as best as I can!

 

I am setting up a store where the customer can put a link to the amazon page of the item, I have a affiliates account so I basically want the link changed to my amazon affialtes link automatically, for example the amazon link for an 80gb ipod is:

 

http://www.amazon.co.uk/Apple-iPod-classic-80GB-black/dp/B000UVS20Y/ref=pd_bbs_sr_1?ie=UTF8&s=gateway&qid=1201475249&sr=8-1

 

while the affiliate link is

 

http://www.amazon.co.uk/dp/B000UVS20Y?tag=speciainvita-21&camp=1406&creative=6394&linkCode=as1&creativeASIN=B000UVS20Y&adid=17MV5PBY277D9CQBV8WA&

 

is there a way in php to do this? Currently the link is stored as $source and when displayed I am currently just using the echo command.

 

Thanks for any help you can give, like I say, I am getting there but I do not understand everything at the moment!

Thought this may explain how its saved better:

 

when the item is entered this code is used:

 

<input name="source" type="text" value="<?php echo htmlspecialchars(stripslashes($source)); ?>" maxlength="255" size="50"/>

 

and when viewed on  another page this is how I have done it:

 

<?php echo htmlspecialchars($row["source"]); ?>
