Help!!!

I am new to this so someone PLEASE HELP ME!!

I have a php form which I am trying to check. My code is shown below (only the piece which is questionable). This code works, however, what I want is the line I currently have commented off. If I comment off the first "if" statement (the one I don't want) I get an error saying "Object Expected". What am I doing wrong? Why will it work for the first if statement but not the second?

<script language="JavaScript" type="text/javascript">
function checkform (form1)
{if (form1.txtJobNo.value == "C"){
//{if (preg_match("/[A-a]{2,2}[0-9]{8,8}/", form1.$jobno)){
alert ("Please enter a valid job number");
return False;}
}

you're just using form 1 you've got to use form1.field.value but you're also mixing and mingling php and javascript you can't do that.

How do I correct this, Please?

You're not running your script through the PHP parser.

You're trying to make the Javascript parser execute PHP code.

What you want to do is...

HTML FORM

<script language="JavaScript" type="text/javascript"> 
function checkform (theform)  {
  if(!theform.yourvar.value) {
   alert('Please enter a valid job number.');
   return false;
  }
  else {
    return true;
  }
}
</script>

<form name="frm" method="post" action="checkform.php" onsubmit="return checkform(this);">
<input type="text" name="yourvar" />
<input type="submit" name="submit" value="Submit" />
</form>

PHP CODE

if(isset($_POST['yourvar']) && !$_POST['yourvar']) {
  extract($_POST);
   if (preg_match("/[A-a]{2,2}[0-9]{8,8}/", $yourvar)) {
    echo "Please enter a valid job number";
   }
}

Haven't checked it, but you should get the general idea.
