Tricky question, eh? I think this is a wrong answer, see, the poster already adds   so that the newlines show up in the html. I almost got fooled with this one too.

Update: Sorry, atcroft, this post was a bit too harsh (or cheeky). I'm now not so sure if param really returns an array or a scalar here. I'd still guess scalar, because anonymonk says in the question

The emails come back with names seperated by CR

for

$/

Anyway, adding a <PRE> is a good solution in either case.

Actually, given that the email displays them as the OP desires, but that he wants the results to show up on the web page in the same manner, <pre></pre> tags around the variable will in fact take care of the issue, without having to worry about looking at the parameter in question as a scalar or array.

Test results, result display section, CGI based on OP's provided code

Test HTML code Displayed

Sample results, original code
<html> <body> Names here: duh Names here: joe bob mary </body> </html>
[download]
Names here: duh
Names here: joe bob mary
Sample results, <pre></pre> tags around $name
<html> <body> <pre> Names here: duh Names here: joe bob mary </pre> </body> </html>
[download]

Names here: duh
Names here: joe bob mary

HTML code, for reference:

<html>
<head>
</head>
<body>
<form action="/cgi-bin/testdump.pl" method=post>
<table>
  <tr><td>Department</td>
    <td><input type=text name=department></td>
  </tr>
  <tr>
    <td colspan=2>People</td>
  </tr>
  <tr>
    <td colspan=2>
      <textarea name=people rows=5 cols=40></textarea>
    </td>
  </tr>
  <tr>
    <td><input type=submit></td>
    <td><input type=reset></td>
  </tr>
</table>
</form>
</body>
</html>

perl code, for reference:

#!/usr/bin/perl

use CGI qw/:standard/;
$| = 1;

foreach my $field (param)
{
  foreach my $value (param($field))
  {
    $name .= "Names here\:\t$value<br />";
  }
}

# Mailer section removed from OP's code for testing

print header, <<EOF;
<HTML>
<BODY>
<pre>
$name
</pre>
</BODY>
</HTML>
EOF

Hope that helps.

Actualy he only puts the br after the value. It looks like its printing "Names:" followed by all the names grouped together. Viewing the source would probably show all the names on seperate lines. I think atcroft is quite right here but then we need the OP to be a little more specific about what he _is_ getting.
