Process Log

webheadcoder

<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.
