I'm a newbie when it comes to Perl so bear with me.  There's a page I have with a form and when the person submits it it'll call itself to check if all fields were entered then go to another page if all were.  But I can't figure out what the function or method is to check if the submit button was pushed.  Any help would be appreciated.

Thanks.

Hi,

you should make the form pass all the fields to your script then go though them checking
then if theres an error display the error message else send the email

You probably have a line like this in your HTML form code, correct?

<INPUT TYPE=SUBMIT NAME="buttonname" VALUE="Button Label" >

This is just like the other values in your form -- it passes the script a variable $buttonname = "Button Label";

So, to check if the submit button was pressed just use this:

if ($buttonname eq "Button Label"){
   #do something
}

I tried that already, it doesn't work.   For example in ASP you have the request.form which you can use to refer to it, but in PERL I'm not sure what it is.  Anyways I found another way around it...

use CGI qw/:standard/;
if( param("buttonname") eq "Button Label" ){
}

Thanks ozo -- I guess I assumed he'd do

$buttonname = param("buttonname");

sorry I left that out in my code above.

Your description is a little unclear.

Do you want to check for the fields being entered *before* the form is submitted or after?

If before, then you need to use Javascript for the validation.  If after, then just check each field name for existence, eg:

use CGI ':standard';

Empty("Field1 is empty") unless param("field1");
Empty("Field2 is empty") unless param("field2");

sub Empty {
  my $msg = shift;
  print header, $msg;
  exit;
}

Adjust the field names to whatever you have in your form.

It may help if you show us the relevant HTML section of your form.
