<p>This plugin allows you to restrict your site users from uploading files of certain types and control the maximum file upload size. Administrator can select the file types and file upload limit by user role. This plugin restricts users from uploading unwanted files using the WordPress media uploader.</p>
<p>It is very simple to use. You will be able give permissions role wise. To restore WordPress’s default selection, just deactivate the plugin.</p>
<p>Any issue? Please let me know (http://sajjadhossain.com/contact-me/).</p>


WP Upload Restriction

This plugin allows you to control upload of files based on file types and sizes.

<p>This plugin uses hooks in the opposite way most plugins do.  You add <code>do_action</code> where you want to do some logging and this plugin will save it to the database only when active.</p>
<h4>Log Activity</h4>
<p>This plugin now logs plugin activity (when activated, deactivated, deleted, updated, installed), when wordpress is updated, and when functions are used wrong or deprecated.</p>
<p>Example:</p>
<pre><code>do_action( 'wp_log_info', 'So far ok', 'Details of what is ok.' );
if ( $something_bad_happened ) {
    do_action( 'wp_log_error', 'This Happened!', 'Details of what happened.' );
    ...
}
</code></pre>
<p>See Tools->Logs to view, delete, and export the logs on the admin side.  Only users with the manage_options capability will have access.</p>
<p>This plugin automatically logs deprecated and doing_it_wrong errors.  The rest is what you add to your code.</p>
<p>You can log what functions will be run for a specific action or filter.  For example if you want to see what runs in the ‘init’ hook:</p>
<pre><code>function check_init_hook() {
    do_action( 'wp_log_debug_hook', 'init' );
}
add_filter( 'init', 'check_init_hook', 0 );
</code></pre>
<p>The following are the different levels of logging to add to your code.  You can use any level how you see fit, the descriptions of each level are just guidelines.</p>
<h4>Emergency</h4>
<p>System is unusable<br />
    do_action( ‘wp_log_emergency’, $label, $message );</p>
<h4>Alert</h4>
<p>Action must be taken immediately.<br />
    do_action( ‘wp_log_alert’, $label, $message );</p>
<h4>Critical</h4>
<p>Critical conditions.<br />
    do_action( ‘wp_log_critical’, $label, $message );</p>
<h4>Error</h4>
<p>Runtime errors that do not require immediate action but should typically be logged and monitored.<br />
    do_action( ‘wp_log_error’, $label, $message );</p>
<h4>Warning</h4>
<p>Exceptional occurrences that are not errors.<br />
    do_action( ‘wp_log_warning’, $label, $message );</p>
<h4>Notice</h4>
<p>Normal but significant events.<br />
    do_action( ‘wp_log_notice’, $label, $message );</p>
<h4>Info</h4>
<p>Interesting events.<br />
    do_action( ‘wp_log_info’, $label, $message );</p>
<h4>Debug</h4>
<p>Detailed debug information.<br />
    do_action( ‘wp_log_debug’, $label, $message );</p>


WP Log Action

Add error or debug logging in your code and leave it there.  Logs will only be recorded with this plugin, otherwise will be ignored.
