After testing all of the AJAX plugins in the WordPress repository, I got frustrated. They’re all great, but it seems that they’re like 90% complete. They still need polishing. This is why I decided to create this plugin
How is this plugin different:
<ul>
<li>Three different templates to choose from: Modal login form, Classic login form and popup login form (jQuery UI based)</li>
<li>24 themes to choose from (jQuery UI based) </li>
<li>Fully customizable: Just copy the template you’re using from /templates/ directory in the plugin to the “ultimate_ajax_login” directory in your theme, and modify as you need to.</li>
<li>After a user is logged in, nothing shows up. I found this pretty frustrating with other plugins, there was no way to hide things.</li>
<li>If you need to show anything after a user logs in, just copy the template widget-logged-in.php to your ultimate_ajax_login folder and add whatever you need. You can call any WP function from there.</li>
<li>Has three templates, one an AJAX-based classic login form, and the other is a jQuery UI dialog box (Tested and works on mobile), and the third one is a popmodal dialog box</li>
<li>Blocks the login form whenever a user is being logged in.</li>
<li>Allows you to specify a global login redirect URL in your settings page, which applies to all of your widgets.</li>
<li>Login redirect URL can be overridden on a per-widget basis from the widget options page.</li>
</ul>
Shortcode Usage
Instead of using the widget, you can insert the shortcode inside any post. If you’re a theme developer, you can use it with the do_shortcode() function. Here are the varius option
<ul>
<li>Using with classic template and no redirect url specified: [ultimate_ajax_login] </li>
<li>Using the dialog box template: [ultimate_ajax_login template=’dialog’]</li>
<li>Using the dialog box template and a jquery theme: [ultimate_ajax_login template=’dialog’ theme=’cupertino’]</li>
</ul>

This plugin will automatically add a login/register link to your ‘primary’ menu location. A nice looking form will popup when the link is clicked. 
Shortcode is also available for use on any post or widget with ‘[wp-ajax-login text=”Login/Register”]’ and ‘text’ attribute is the link text.
