Posting Source Code in WordPress, Take 2

In my searching, I have found another WordPress source code plugin, called wp-syntax. This one uses GeSHi, the Generic Syntax Highlighter. It features many languages, and is extensible to even more. (If I ever post a COBOL snippet, I'll probably add COBOL support to it, and contribute it to the codebase.)

To use it, you simply put a pre tag, followed by lang=[language]. It will also do line numbering. Of course, with a single “language” parameter, the embedded language will not be highlighted as well. In this case, the previous plug-in works better; although the syntax highlighting has to be done manually, it can handle multiple languages.

(NOTE: The samples have been removed, as this blog is not running under WordPress. However, since the source code from another post was moved here, it is presented below using myWebLog's code highlighting.)

<?php
/**
 * This creates a list of category links that can be used with a category dropdown
 */
$aCategories = get_all_category_ids();
$iMaxCat = 0;
foreach($aCategories as $iThisCat) {
    if ($iMaxCat < $iThisCat) {
        $iMaxCat = $iThisCat;
    }
}
$iMaxCat++;
?>
<div style="text-align:center;">
<form name="categoryform" action="" style="text-align:center;">
    <script type="text/javascript">
        var aLink = new Array(<?php echo($iMaxCat); ?>);
<?php
foreach($aCategories as $iThisCat) {
    echo("aLink[$iThisCat] = \"" . get_category_link($iThisCat) . "\";\n");
} ?>
        function goCat() {
            window.location =
                aLink[document.getElementById('cat')[document.getElementById('cat').selectedIndex].text;
        }
    </script>
    <?php wp_dropdown_categories('class=sidebardropdown&orderby=name&show_count=1&hierarchical=1'); ?>
    <br /><br />
    <button class="sidebarbutton" type="button" style="margin-top:5px;" onclick="goCat();">View Category</button>
    </form>
</div>

This is another option, and is probably what I'll use for single-language posts, or posts where the embedded language may not be crucial.
