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.
