brucey - I have an old .cgi file that I need to update and I have an extremely limited knowledge of perl...

I need to integrate the application with a new website, the existing code is about 6 years+ old and contains more presentation elements in the code than content... I?ll be sorting that out!

firstly, rather than PRINT NEWPAGE on every line, research has led me to believe that << EOF then prints out everything from then on until it reaches EOF

code:

<< ENDHTML 



[ html goes here]



ENDHTML

The question is can you have dynamic values within << tags i.e. $shoes that will output the code with the value for shoes?

Also I need to convert the perl script to open links in the same window rather than a pop-up. I think the code for this is a mixture of Javascript and PERL.

Directly after the PRINT NEWPAGE lines have finished I find this:

code:

....

print NEWPAGE "</form></body></html>\n";



close(NEWPAGE);

	&new_window;

	}



sub new_window {

	print <<"END";

<SCRIPT LANGUAGE="JavaScript">

popwin = window.open("http://www.domain.co.uk/domain/jobpages/$cleanval.html","infowin","resizable=no,scrollbars=yes,width=430,height=450,top=35,left=75");

</SCRIPT>

<body onload="document.check.submit(); return true;">

  <form method=post action="javascript:history.back()" name="check">

  <input type="Hidden" name="dummy" value="dummy">

  </form>

</body>



END



exit;

then further down the script we find the call

code:

<a href=\"/cgi-bin/domain/jobsearch.cgi?command=info&val=$refnum&db=$FORM{'call'}\">MORE INFO</a></font></td></tr>\n";

<<EOF is known as Heredoc syntax. Herdoc allows you to use single & double quotes without having to escape the characters. Variables may be used inside the Heredoc.

Both Perl and PHP support Heredoc. It is a very convienent way to deal with large blocks of HTML or XML .

BTW- I'm not sure who brucey is, but I hope this helped.
