| Plugin Name: The Great WordPress Admin Menu Challenge of Jan 2011 | |
| Description: <em>"The Great WordPress Admin Menu Challenge of Jan 2011"</em> was inspired by the WordPress team's apparent lack of understanding of the problems addressed by trac tickets <a href="http://core.trac.wordpress.org/ticket/16048">#16048</a> and <a href="http://core.trac.wordpress.org/ticket/16050">#16050</a> <em>(See also: <a href="http://core.trac.wordpress.org/ticket/16204">#16204</a>)</em> and suggestion that the <a href="http://wordpress.org/extend/plugins/admin-menu-editor/>Admin Menu Editor</a> plugin handles the use-cases that the tickets address. Debate spilled over onto Twitter with participation from <a href="http://twitter.com/nacin">@nacin</a>, <a href="http://twitter.com/aaronjorbin">@aaronjorbin</a>, <a href="http://twitter.com/petemall">@petemall</a>, <a href="http://twitter.com/westi">@westi</a>, <a href="http://twitter.com/janeforshort">@janeforshort</a>, <a href="http://twitter.com/PatchesWelcome">@PatchesWelcome</a>; supportive comments from <a href="http://twitter.com/ramsey">@ramsey</a>, <a href="http://twitter.com/brianlayman">@brianlayman</a>, <a href="http://twitter.com/TheLeggett">@TheLeggett</a>, a retweeting of @nacin's simple yet <em>(AFAICT)</em> insufficient solution by <a href="http://twitter.com/vbakaitis">@vbakaitis</a>, <a href="http://twitter.com/Viper007Bond">@Viper007Bond</a>, <a href="http://twitter.com/nickopris">@nickopris</a>, <a href="http://twitter.com/Trademark">@Trademark</a>, <a href="http://twitter.com/favstar_pop">@favstar_pop</a>, <a href="http://twitter.com/designsimply">@designsimply</a>, <a href="http://twitter.com/darylkoop">@darylkoop</a>, <a href="http://twitter.com/iamjohnford">@iamjohnford</a>, <a href="http://twitter.com/markjaquith">@markjaquith</a>, <a href="http://twitter.com/JohnJamesJacoby">@JohnJamesJacoby</a> and <a href="http://twitter.com/dd32">@dd32</a>. Also see <a href="http://andrewnacin.com/2010/12/20/better-admin-menu-controls-custom-post-types-wordpress-3-1/#comment-6360">comments</a> on @nacin's blog post entitled "<em>Better admin menu handling for post types in WordPress 3.1</em>." <strong>The desired goal of the <em>"challenge"</em></strong> is to simply either to find a solution that has eluded me or, to get those who are dismissing it as solvable without added hooks in WordPress to have a tangible example to explore in hopes they will recognize that there is indeed a need for at least some of the requested hooks. <strong>There are three (3) steps to the challenge:</strong> 1.) Get the "Microsite" submenu page to be highlighted when editing an Attorney, 2.) Get the Attorney Menu Page link to link <a href="/wp-admin/edit.php?post_type=attorney">here</a> when editing an Attorney, and 3.) Get the "Microsite" link not to trigger a "You do not have sufficient permissions to access this page" error. Here is <a href="http://mikeschinkel.com/websnaps/skitched-20110114-235302.png" target="_blank"><strong>a screenshot</strong> that attempts to illustrate the callenge</a>. The code can be found on gist <a href="https://gist.github.com/780709"><strong>here</strong></a>. Activate it as a plugin in a WordPress 3.1 install and go <a href="/wp-admin/post.php?post=10&action=edit"><strong>here</strong></a> to see what the screenshot illustrates. <strong>Be sure to load the <a href="http://mikeschinkel.com/websnaps/skitched-20110114-235302.png" target="_blank">screenshot</a> in another browser tab or window first</strong>. | |
