Update change PHP database script

I have a databse setup however the script that was designed for me when i add a ' it adds a forward slash every time i save any data on the database within the diary where i entered the '. For example if i typed " Don't do that " i get " Don'/t do that " then after say editing various other fields multile times i then get " Don'//////////////////////////////////////////////////////////////////////////////////////////////////t do that " or more and it deletes the data that was there. I have been told to look up the use of mysql_real_escape_string and don't use add_slashes at all aparantly a simple job if you know what you are doing I forum post here if it helps [login to view URL],395628 On the assumption this is a quick job as i have been advised looking at bids of around $10-$30 unless you can advise otherwise. Part of the script is uploaded here if you need more we can discuss this but I think this is all you need , Any questions let me know looking to gt this done ASAP
