<p>With this plugin you can create a link to post-new.php (the place to create a new page) that includes the desired parent_id of the new page. This allows you to create links in the front end of the website like “Add a new page to this section” or “Create a new sub-page”. This is extremely useful when developing custom themes to add useful backend links on the front end of the site for users who have editing access. For using wordpress as a CMS, you really want to let the user avoid going through the clunky manage pages interface…</p>
<h4>Features</h4>
<ul>
<li>This should be a feature of wordpress</li>
<li>I can’t believe this isn’t built into wordpress</li>
<li>This has to rely on javascript because there’s no suitable hook to do it another way</li>
<li>Did I mention this should be built into wordpress?</li>
</ul>
<h4>Feedback</h4>
<p>Doubt you’ll have any, but if you do, you can go to my website (http://theoephraim.com)<br />
I was thinking about making some functions to actually spit out the links, but since were talking about developing custom themes, you may as well just hardcode it.</p>
