I have created a CGI script that prints the parameters of an integrated html form along with their values. In essence, it is a user application form that prints a confirmation message to the user after it is submitted. This has been accomplished, but my next task is form validation. I have tried dozens of examples, but I can’t get anything to work for my form.
As opposed to creating an html form and having it use a separate CGI script (IE form action=script.cgi), I simply printed a huge block of html code (the form) after the CGI script that prints the parameters. So, my script and form is contained on just one file, userapp.cgi.
Anyway, if anyone could just write me a few lines of code that would at least validate maybe one of my text fields (IE a pop-up that tells the user the First Name field is empty), I would be very grateful. If I can get the validation to work with one field, than I can do the rest of the dirty work applying it to all of them.
here is my script:
#!/usr/bin/perl
use CGI ‘:standard’;
print header;
print start_html(‘Code 974 New User Account Application Form’);
if (param()) {
print ‘<body bgcolor=FFDAB9><a href=”http://hsb.gsfc.nasa.gov”><img SRC=”gif/hydro.sm.gif” align=”left” valign=”top”></a><a href=”http://www.nasa.gov”><img SRC=”gif/NASAlogo.gif” valign=”top” align=”right”></a></align>
<center><h1>Thank You</h1>’;
print “<br><i><h2>Your information has been succesfully submitted</h2></i><br><hr><br><br></center>”;
my @params = param();
foreach my $parameter(@params) {
print “<b>”, $parameter,”</b>”, ” – “, param($parameter),”<br>”;
}
print ‘<br><center><font size=”+2″>To resubmit, please click <a href=”
print ‘<hr color=”” size=5 width=90%>
</center><pre>
