Gigaom Copy Active Plugins

Utility WP plugin for importing/exporting active plugins

Cristian Beckerle

This plugin is an improvement to the current WordPress plugin installation methods. It allows you to install one or more plugins simply by typing their names or download URLs in a textarea.
All credit goes to improvingtheweb. This plugin is only a modification of <a href="https://wordpress.org/extend/plugins/improved-plugin-installation/" rel="ugc">Improved Plugin Installation</a>. The idea was to run the original plugin in the newer versions of WordPress. That’s it. Also, we cut off the bookmarklet feature.
Thank you very much for the contributions: <a href="https://profiles.wordpress.org/drewapicture/" rel="nofollow ugc">drewapicture</a>
Example
The installation form will accept any of these inputs:
<ul>
<li>Contact Form 7</li>
<li>https://wordpress.org/extend/plugins/contact-form-7/</li>
<li>https://downloads.wordpress.org/plugin/contact-form-7.3.3.2.zip</li>
</ul>
Plugins don’t need to be hosted at wordpress.org. As long as you use the direct download URL, third party plugins will install without a problem.

Bulk Plugin Installation

Allows you to install one or more plugins simply by typing their names or download URLs in a textarea.
