Posting Source Code in WordPress, Take 2

June 13, 2007 at 11:33 am by Daniel · Filed under PHP, WordPress

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.

Here is what the example from the “Category DropDowns in WordPress” post looks like with lang="php"…

<?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</span>($iThisCat) . "\";\n");
} ?>
        function goCat() {
            window.location =
                aLink[document.getElementById('cat')[document.getElementById('cat').selectedIndex].value];
        }
    </script>
    <?php wp_dropdown_categories('class=sidebardropdown&orderby=name&show_count=1&hierarchical=1'); ?>
    <br />
    <button class="sidebarbutton" type="button" style="margin-top:5px;" onclick="goCat();">View Category</button>
    </form>
</div>

And, here’s what it looks like with lang="javascript"…

<?php
/**

*/
$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</span>($iThisCat) . "\";\n");
} ?>
        function goCat() {
            window.location =
                aLink[document.getElementById('cat')[document.getElementById('cat').selectedIndex].value];
        }
    </script>
    <?php wp_dropdown_categories('class=sidebardropdown&orderby=name&show_count=1&hierarchical=1'); ?>
    <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.

    I started this thread to evaluate public available web proxies:

    Which are really anonymous?

    Which can unblock facebook, myspace etc, in other words: are fresh ?

    Which would you recommend?

    Thanks for your help,
    Dschibut

    P.S.: In my country, the freedom of speech is somehow constrained, please give me a hint, if you are not sure about your recommendation.
