Arrays, HTML, and PHP
Tim Perdue picture of Tim Perdue
Sorry I haven't updated PHPBuilder is SO long, but I've been a bit busy helping build a new web site called SourceForge. While building the site, I stretched my knowledge of PHP and databases and thought I would share a few things I learned.
A lot of people ask about passing arrays and using checkboxes/select boxes in PHP, so that's what I'll cover today.
To pass multiple values, as in a "Multiple Select Box", put [] after the variable name, like assigned_to[].
<SELECT NAME="assigned_to[]" MULTIPLE SIZE="8">
    <OPTION VALUE="100">None</OPTION>
    <OPTION VALUE="2">dtype</OPTION>
    <OPTION VALUE="4">tim_perdue</OPTION>
    <OPTION VALUE="5">fusion94</OPTION>
    <OPTION VALUE="3">precision</OPTION>
    <OPTION VALUE="18">michael</OPTION>
    <OPTION VALUE="157">jbyers</OPTION>
    <OPTION VALUE="251">Lectric</OPTION>
    <OPTION VALUE="149">baddog</OPTION>
    <OPTION VALUE="105">mrzenn</OPTION>
</SELECT>
Then on the receiving page, you simply do a count() on assigned_to, and iterate through the list of values that was selected.

<?php

$count=count($assigned_to);

for ($i=0; $i<$count; $i++) {
    echo $assigned_to[$i];
}

?>
