I have a textarea in a form, when I enter special characters in it, I get an error in mysql. (when submitting the form to a php-file which does the work of inserting into mysql)
I need to know exactly what characters that aren't allowed, or easier would be, exactly what characters thar ARE allowed, so that I could validate the textarea before submitting.
Does anybody know?
I have tried mysql_real_escape_string() but didn't help...
NOTE: In the textarea, users are supposed to enter some special chars like these:
+ , . ; : - _ space & % ! ? = # * ½ @ / \ [ ] ' " < > £ $ €
Probably got them all...
how can I do this?
Thanks

My mysql_query :
mysql_query("INSERT INTO cars_db (description) VALUES ('$ad_text')");
UPDATE
Mysql error:
