SQL ERROR 1064 - Think it is a single quote error

[alqadir]

Hi Guys,
I was hoping someone out there can help me out with this sql error I am having. I am thinking it has something to do with " ' " single quotes. In the code a user can input text into a text box. The data stored in this text box is assigned to a string variable,which is stored in the database via an sql statement. The code works fine until a " ' " is used in the text box.

Here is the error:

Database error in vBulletin 3.0.4:

mysql error number: 1064

one solution might be to search the string for the invalid character.
is there a try catch routine with php?
