Arrays, HTML and PHP

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];
}
?>
