Nevermind…figured it out! 😊 Should have just tried a little harder before posting.
For anyone else interested:
<form id=‘member_delete_form’ method=“post” action=“http://www.yourdomain.com/”><br />
<div class=‘hiddenFields’><br />
<input type=“hidden” name=“XID” value=”{XID_HASH}” /><br />
<input type=“hidden” name=“ACT” value=“16” /><br />
<input type=“hidden” name=“site_id” value=“1” /><br />
You must type in your password to remove your account:</p>
<p><input type=“password” style=“width:80%” class=“input” name=“password” size=“20” value=”” maxlength=“32” /></p>
<p><br />
Are you sure you wish to delete your account? All purchases and other content associated with your account will also be deleted. <strong>THIS ACTION CANNOT BE UNDONE</strong>.</p>
<p><br />
<input type=“submit” class=“submit” value=“Submit” />
For the ACT id, you can also generate that through PHP instead of hard-coding it.
Cheers!
