( #3333=superdoc: print w/replies, xml ) Need Help??

Try this simple cgi to show the benefit of using Dumper.

#!perl # Dumper demo cgi use strict; use Data::Dumper; print "Content-Type: text/html\n\n"; print '<pre>'; my $ref = [ { ID => 'ABC'},{ ID => 'DEF'},{ ID => 'GHI'} ]; print '<h2>$ref</h2>'; print Dumper $ref; print '<hr/>'; my @array = map { $_->{ID} } @$ref; print '<h2>@array</h2>'; print Dumper @array; print '<hr/>'; my @error = @array."\n"; print '<h2>@error</h2>'; print Dumper @error; print '<hr/>';

Also, note how map could be used to replace this code in search_item()

my @array = @$resultsRef foreach my $hit (@array) { # $hit is a hash reference. my %hash = %$hit; push @searched, $hash{ID}; }

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
