What I am having problems with is that I want "price" to be modified to be an array of prices. So some of the zip files would have one price, while others may have two or more.
my @file_attachments = (
{file => 'test1.zip', price => '10.00', desc => 'the 1st test'},
{file => 'test2.zip', price => '12.00', desc => 'the 2nd test'},
{file => 'test3.zip', price => '13.00', desc => 'the 3rd test'},
{file => 'test4.zip', price => '14.00', desc => 'the 4th test'}
);
# Get the number of items (hashes) in the array.
my $file_no = scalar (@file_attachments);
# $file_no is now: 4 in this instance as there is 4 hashes in the
+ array.
# Looping through the hash and printing out all the hash "file" e
+lements.
for (my $i=0; $i < $file_no; $i++)
{
print '$file_attachments[$i]{'file'} is:'. $file_attachments[$i]{'fil
+e'}."\n";
}
# Looping through the hash and printing out all the hash "price"
+elements.
for (my $i=0; $i < $file_no; $i++)
{
print '$file_attachments[$i]{'price'} is:'. $file_attachments[$i]{'pri
+ce'}."\n";
}
# Looping through the hash and printing out all the hash "desc" e
+lements.
for (my $i=0; $i < $file_no; $i++)
{
print '$file_attachments[$i]{'desc'} is:'. $file_attachments[$i]{'desc
+'}."\n";
}
Sample code came from here:

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).
