\nSorry I haven’t updated PHPBuilder is SO<\/b> long, but I’ve been a bit busy
\nhelping build a new web site called SourceForge<\/a>.
\nWhile building the site, I stretched my knowledge of PHP and databases and thought
\nI would share a few things I learned.<\/div>\n
\nA lot of people ask about passing arrays and using checkboxes\/select boxes in PHP,
\nso that’s what I’ll cover today.<\/div>\n
\nTo pass multiple values, as in a “Multiple Select Box”, put [] after the variable name,
\nlike assigned_to[]<\/b>.<\/div>\n
\n
\n<SELECT\u00a0NAME=\"assigned_to[]\"\u00a0MULTIPLE\u00a0SIZE=\"8\">
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"100\">None<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"2\">dtype<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"4\">tim_perdue<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"5\">fusion94<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"3\">precision<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"18\">michael<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"157\">jbyers<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"251\">Lectric<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"149\">baddog<\/OPTION>
\n
\u00a0\u00a0\u00a0\u00a0<OPTION\u00a0VALUE=\"105\">mrzenn<\/OPTION>
\n
<\/SELECT><\/span>
\n<\/code><\/font><\/div>\n
\nThen on the receiving page, you simply do a count() on assigned_to, and iterate
\nthrough the list of values that was selected.<\/div>\n
\n<\/p>\n

<?php<\/p>\n

$count<\/span>=<\/span>count<\/span>(<\/span>$assigned_to<\/span>);<\/p>\n

for\u00a0(<\/span>$i<\/span>=<\/span>0<\/span>;\u00a0<\/span>$i<\/span><<\/span>$count<\/span>;\u00a0<\/span>$i<\/span>++)\u00a0{
\n
\u00a0\u00a0\u00a0\u00a0echo\u00a0<\/span>$assigned_to<\/span>[<\/span>$i<\/span>];
\n
}<\/p>\n

<\/span>?>
\n
<\/span>
\n<\/span>
\n<\/code><\/font><\/div>\n<\/div>\n
