So, right now if the form field variable is blank it errors out with below code, but I have been getting a lot of spam submissions on my form and they have been typing in URLs in field. How can I modify the below so that if they put a URL that is will also error out? Thanks in advance for any help! else if(!$_POST['description']) { print "<table style='border-collapse: collapse' id='AutoNumber1' border='0' bordercolor='#111111' cellpadding='0' cellspacing='0' width='100%'> <tr> <td width='38%'> <p align='right'> <img class='decoded' alt='error.png' src='error.png'></td> <td width='26%'> <p align='center'><u><font size='5' color='#FF0000'><b>DESCRIPTION ERROR</b></font></u></td> <td width='36%'> <img class='decoded' alt='error.png' src='error.png'></td> </tr> <tr> <td colspan='3' width='100%'> <p align='center'><font size='1'>The Site Description field cannot be blank, or cannot include and URLs.</font></td> </tr> <tr> <td width='100%' colspan='3'> </td> </tr> <tr> <td width='100%' colspan='3'> <p align='center'><a href='javascript:javascript:history.go(-1)'>Click here to go back to previous page</a></td> </tr> </table>";}

I have been getting a lot of bots spamming this script, and need to add captcha to it. I am new to php and was wondering if someone would help me with this issue. Below is the script, and I really would appreciate the help. <?php include "admin/conf.php"; $setting1="SELECT * FROM ".$prefix."settings"; $setting2=mysql_query($setting1) or die("Sorry, Could not select sites table"); $setting=mysql_fetch_array($setting2); include "lang/$setting[lang]/main.php"; print "<title>$lang_reg1</title>"; print "<link rel='stylesheet' href='skin/$setting[style]/style.css' type='text/css'>";

I tried to add 3 fields to this form, but can't seem to get it to work. Can someone take a peak at it to see if they can tell me what I am doing wrong? Thanks in advance <?php // Define your email address - where to send messages - here define("MAIL_TARGET","dfsdf@dfdsf.com"); // Here you can redefine error messages define("errorName","Invalid name!
