A new Threaded Wordpress Comments Plugin

**jamestl2** · 04-29-2008, 09:59 PM

I've been working on trying to code this sort of feature into my blog all day for the past few days, and with the plugins I've tried (Brian's Threaded Comments, Ajax, etc.), I've been getting errors everywhere, no current theme CSS, etc. It's been really frustrating

. (and the WP.org forums haven't been much help either

)

Basically what I wanted to do was have a system similar to what those plugins offer, but..... I want:

Just the ability to indent a few levels, replying to the above comment (It'd be nice if the form could move too, like with the BTC plugin)
To use my theme's current comment stylesheet (I already like the way my comment styles and colors look)
And I do NOT want a new comments.php page. (which is what all those WP plugins seem to come with)

I was thinking about just taking the code from each of the files Brian's TC plugin offers, and just making one whole php page plugin out of it, but I'd have no idea what to move to where.

Here's Brian's Threaded Comments' Plugin's code:

PHP Code:

04-29-2008, 09:59 PM	#1 (permalink) A new Threaded Wordpress Comments Plugin
jamestl2 Hey..... Latest Blog Post: How to Fix the SRG Clean Archives Wordpress 2.5 Pl... Posts: 1,576 Name: James, if you couldn't tell from my username Talkupation:	I've been working on trying to code this sort of feature into my blog all day for the past few days, and with the plugins I've tried (Brian's Threaded Comments, Ajax, etc.), I've been getting errors everywhere, no current theme CSS, etc. It's been really frustrating . (and the WP.org forums haven't been much help either ) Basically what I wanted to do was have a system similar to what those plugins offer, but..... I want: Just the ability to indent a few levels, replying to the above comment (It'd be nice if the form could move too, like with the BTC plugin) To use my theme's current comment stylesheet (I already like the way my comment styles and colors look) And I do NOT want a new comments.php page. (which is what all those WP plugins seem to come with) I was thinking about just taking the code from each of the files Brian's TC plugin offers, and just making one whole php page plugin out of it, but I'd have no idea what to move to where. Here's Brian's Threaded Comments' Plugin's code: PHP Code: <?php /* Plugin Name: Brian's Threaded Comments Plugin URI: http://meidell.dk/threadedcomments/ Version: 1.5.18 Description: This gives you threaded comments and a "wandering" comment form. Author: Brian Meidell Author URI: http://meidell.dk/ Changelog: version 1.5: Released for WP1.5 version 1.5.1: Added error message for missing form field version 1.5.2: Fixed stupid bug from last release version 1.5.3: Much more comprehensive error messages to help with diagnosis of problems. Added login patch from Salil Deshpande. Added auto-integration with subscribe-to-comments. version 1.5.4: A fix to Salil Deshpandes patch - proper login required code, thanks to Salil again. Renamed maybe_add_column to prevent conflicts with other plugins. version 1.5.5: Added an options panel called "Threaded Comments" for the few settings version 1.5.6: Changed comment_reply_ID form field to use comment_form hook instead, making it compatible with other plugins using this hook. Thanks to Martey of www.marteydodoo.com for pointing this out. version 1.5.7: Included bugfix from Zhou Qingbo version 1.5.8: Fixed php opening tags to be verbose, as suggested by Michael Carrino version 1.5.9: Changed plugin to use only existing database columns, and added migration code from older versions version 1.5.10: Changed nesting levels setting so it correctly reflects the nesting level (it was one off) version 1.5.11: Fixed taborder. Thanks to RJ Matthis (http://blog.reformatthis.com) / Ryan J Parker (http://www.ryanjparker.net) version 1.5.12: Fixed missing php opening tag version 1.5.15: Fixed closed/open comments bug and deploy script version 1.5.16: Big thanks to NSpeaks - Fixed issues mentioned in this post: http://nspeaks.com/149/hacking-brian’s-threaded-comments-plugin/ version 1.5.17: Fixes from this article implemented: http://www.howtospoter.com/web-20/wordpress/fixing-brians-threaded-comments-plugin - thanks to Alex Sysoef version 1.5.18: Added gravatar support for wp2.5 and myavatars, thanks to Alex Sysoef / /* * Images / $images = array(); $images['subscribed.png'] = "iVBORw0KGgoAAAANSUhEUgAAABUAAAAICAMAAAAhgUThAAAABGdBTUEAAK/INwWK6QAAABl0RVh0U29mdHdhcmUAQWRvYmUgSW1hZ2VSZWFkeXHJZTwAAAAGUExURai0vvP8+20m9Z0AAAACdFJOU/8A5bcwSgAAAE5JREFUeNpiYAQBBhBGAgABxAARZYBgRigPIIBgchAI1cgAEEBwFWDlUNMYAAIIWS3cIAaAAEIyFy7OyAAQQAxIbkDYBhBAcCaKywACDAAgyABfpZamZwAAAABJRU5ErkJggg=="; $images['subthread.png'] = "iVBORw0KGgoAAAANSUhEUgAAAA0AAAANCAYAAAEF7NTqAAAABGdBTUEAAK/INwWK6QAAABl0RVh0U29mdHdhcmUAQWRvYmUgSW1hZ2VSZWFkeXHJZTwAAACmSURBVHjaYvz//z8DCAAEEBMDFAAEECNMBCCA4CIAAQQXgQGAAGJiQAMAAYSiAiCAGIEYzgMIIBSlAAGEogwggBignP/oGCQOEEAYNiADgADCKwkQQBiOhQGAAGIByzIyosgCFTMCBBBOHQABhFMHQADh1AEQQDh1AAQQTh0AAYRTAh8ACCBEzKBZhY8PEEBMDGQAgAAiSxNAAJGlCSCAyAoIgAADAEniPAbcSIg9AAAAAElFTkSuQmCC"; $images['subthread-open.png'] = "iVBORw0KGgoAAAANSUhEUgAAAA0AAAANCAYAAAEF7NTqAAAABGdBTUEAAK/INwWK6QAAABl0RVh0U29mdHdhcmUAQWRvYmUgSW1hZ2VSZWFkeXHJZTwAAACoSURBVHjaYvz//z8DCAAEEBMDFAAEECNMBCCA4CIAAQQXgQGAAGJiQAMAAYSiAiCAQOg/VOA/QAChKAUIIBRlAAHEAFOCjkHiAAGEYQMyAAggvJIAAYThFBgACCAWsCwj4380dzICBBBOHQABhFMHQADh1AEQQDh1AAQQTh0AAYRTAh8ACCBEzKBZhWE6kjxAADExkAEAAogsTQABRJYmgAAiKyAAAgwA3YE+/1F5tWAAAAAASUVORK5CYII="; $images['spacer.png'] = "iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVQI12NgYGBgAAAABQABXvMqOgAAAABJRU5ErkJggg=="; if(isset($_GET['image'])) { header("content-type: image/png"); print base64_decode($images[$_GET['image']]); exit; } function btc_options_page() { global $wpdb; ?> <div class="wrap"> <?php $col = $wpdb->get_col("DESCRIBE {$wpdb->comments} comment_reply_ID"); $col = count( $col ); ?> <?php if( $col && !get_option("btc_migrated") ) { ?> <h2><?php _e('Upgrade Threading'); ?></h2> <form name="form2" method="post" action="<?php echo $_SERVER['REQUEST_URI']; ?>"> <table width="100%" cellspacing="2" cellpadding="5" class="editform"> <tr valign="top"> <th width="33%" scope="row"><?php _e('Migrate Threading') ?></th> <td> <?php if( isset($_REQUEST['btc_upgrade']) ) { $wpdb->query("UPDATE {$wpdb->comments} SET comment_parent=comment_reply_ID WHERE comment_parent = 0"); update_option("btc_migrated", 1 ); ?> Done migrating comments. <?php } else { ?> <input type="submit" name="btc_upgrade" value="Migrate now" /> <br /> Migrate threading from older version of Brians Threaded Comments plugin. <?php } ?> </td> </tr> </table> </form> <?php } ?> <h2><?php _e('Brians Threaded Comments Options') ?></h2> <form name="form1" method="post" action="options.php"> <input type="hidden" name="action" value="update" /> <input type="hidden" name="page_options" value="btc_nestinglevels,btc_shrinkby,btc_customtarget,btc_separate_trackbacks" /> <table width="100%" cellspacing="2" cellpadding="5" class="editform"> <tr valign="top"> <th width="33%" scope="row"><?php _e('Max Nesting Levels:') ?></th> <td><input name="btc_nestinglevels" type="text" id="btc_nestinglevels" value="<?php form_option('btc_nestinglevels'); ?>" size="5" /></td> </tr> <tr valign="top"> <th scope="row"><?php _e('Shrink Font By %:') ?></th> <td><input name="btc_shrinkby" type="text" id="btc_shrinkby" value="<?php form_option('btc_shrinkby'); ?>" size="5" /> <br /> <?php _e('Enables shrinking the font by n percent per nesting level.
