I am submitting a form that will replace matching fields in a template file with what was submitted.
The template file takes this form:
LABEL1: [field1]
LABEL2: [field2]
LABEL3: [field3]
I open the template file, read each line into an array, then start working on each line as follows:
foreach $File (@File) {
$File =~ s/\n//;
foreach $Field (@InputFields) {
$ReplaceVar = $FORM($Field);
$SearchVar = '\[' . Field . '\]';
$File =~ s/$SearchVar/$ReplaceVar/g;
}
print "$File\n";
}
QUESTIONS:
1. If someone does not fill Field1 in the form, the printout will show " LABEL: [Field1] ". How do I get rid of this. Do I first run the above, then run it again searching " '\[.*\]' " and replacing it with ""? I tried this but running it a second time erased all the fields.
2. What does " $File =~ s/\n//; " accomplish?
Thanks!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
