Prevent URL's in form submission

[wmckinn]

Hello,

I have very little experience with php, and would like some advice.

 

I need a way to prevent URL's from being inserted into form fields. I have not been able to discover how to do this. Our forms are being submitted with junk URL's in the form fields. I would like to either A) Kill the form processing if URL's are posted, or B) Provide a pop up message stating that URL submissions are not allowed.

 

Does anyone have any ideas?

 

Thanks,

Walt

create a check function that runs onSubmit of the form, it checks the strings from the forms and parses them through the function to see if a url is present, if so it returns false, if not it returns true, lets call out function checkurl().

 

function checkurl($string)
{
// Stuff that spammers post with:
$bad_strings = array('www.','/url]','ttp://','ttps://') ;
foreach( $bad_strings as $bad_string )
{
if ( ereg( $bad_string, $string ) )
{ 
return false ;
}
else
{
return true;
}
}
}

you may also want to add TLD's to the array such as .com, .net, .us, .biz, .org, ect......
