<p>RHJ4 Notifications and its sibling, RHJ4 Diagnostics solve problems that have plagued programmers for years: How to communicate with users in a clean, clear and visually consistent fashion regardless of where in the program the message originates.</p>
<p>A notification message can be sent from jQuery code in the browser or from PHP code in the server. Either type of message can be displayed immediately or queued for display after the next page turn.</p>
<p>Notifications appear as popup messages on the bottom right corner of the screen and can stay on the screen until the user clicks on them or they can disappear after five seconds.</p>
<p>Using this plugin, a message can be sent easily from a single line of PHP code:</p>
<pre><code>    rhj4_notification('Warning! Danger, Will Robinson!', NOTIFICATION_TYPE_WARNING);
</code></pre>
<p>The same messsage can be sent from jQuery code running in the browser:</p>
<pre><code>    jQuery.notification('Warning! Danger, Will Robinson!',
    jQuery.notification.type('warning'));
</code></pre>
<p>By default, notifications will disappear from the screen after five seconds; however, to make a notification “sticky”, add true as the third argument to either the PHP or jQuery functions:</p>
<pre><code>    jQuery.notification('Warning! Danger, Will Robinson!',
    jQuery.notification.type('warning'), true);
</code></pre>
<p>Notifications can be displayed immediately or queued in the wp_notifications table for display later. The wp_notifications table is created when the plugin is enabled. To “enable” this plugin, see Settings and click on the “Enable” checkbox.</p>
<p>RHJ4 Notifications supports 15 types of notifications</p>
<h3>Usage</h3>
<p>A notification consists of a:</p>
<ul>
<li><strong>Message</strong> – some text to be shown to the user.</li>
<li><strong>Notification Type</strong> – an integer in the range -1..13 that indicates the style of the notification.</li>
<li><strong>Sticky</strong> – a boolean that indicates whether the message should disappear after a few seconds or “stick” around.</li>
</ul>
<h3>Notification Types</h3>
<p>These constants are in the global name space:</p>
<ul>
<li>NOTIFICATION_TYPE_DIAGNOSTIC      = -1;</li>
<li>NOTIFICATION_TYPE_LOG             = 0;</li>
<li>NOTIFICATION_TYPE_SYSTEM          = 1;</li>
<li>NOTIFICATION_TYPE_ERROR           = 2;</li>
<li>NOTIFICATION_TYPE_WARNING         = 3;</li>
<li>NOTIFICATION_TYPE_CONFIRMATION    = 4;</li>
<li>NOTIFICATION_TYPE_MESSAGE         = 5;</li>
<li>NOTIFICATION_TYPE_TEST            = 6;</li>
<li>NOTIFICATION_TYPE_DATA            = 7;</li>
<li>NOTIFICATION_TYPE_COMMENT         = 8;</li>
<li>NOTIFICATION_TYPE_TIP             = 9;</li>
<li>NOTIFICATION_TYPE_REMINDER        = 10;</li>
<li>NOTIFICATION_TYPE_DATE            = 11;</li>
<li>NOTIFICATION_TYPE_VALIDATION      = 12;</li>
<li>NOTIFICATION_TYPE_TIMER           = 13;</li>
</ul>
<p>There are four different interfaces available in the Notifications plugin:</p>
<ul>
<li>Global Functions</li>
<li>Class Methods</li>
<li>jQuery plugin</li>
<li>Short Codes</li>
</ul>
<h3>PHP Global Functions</h3>
<h4>Generate a notification</h4>
<pre><code>rhj4_notification($message, $type = NOTIFICATION_TYPE_MESSAGE, $sticky = FALSE);
</code></pre>
<h3>PHP Class Methods</h3>
<h4>RHJ4Notifications::instance()</h4>
<p>Return an instance of this plugin. This usage allows code in multiple places to use the same instance without having to reinitialize the plugin every time.</p>

<pre><code>    $myInstance = RHJ4Notifications::instance()    
</code></pre>
<h4>init($args)</h4>
<p>Initialize plugin using any of the options defined in $args (see “options” for a list of supported options).</p>
<h4>kill()</h4>
<p>Kill the current instance.</p>
<h4>activate()</h4>
<p>Activate this plugin.</p>
<h4>deactivate()</h4>
<p>Deactivate this plugin.</p>
<h4>options ($options = null)</h4>
<p>Validate options and return valid array. The supported options are:</p>
<p>–<strong>enable</strong>: enable generation of diagnostic messages.</p>
<p>–<strong>log</strong> = {true|false}: enable log notifications</p>
<p>–<strong>system</strong> = {true|false}: enable system notifications</p>
<p>–<strong>error</strong> = {true|false}: enable error notifications</p>
<p>–<strong>warning</strong> = {true|false}: enable warning notifications</p>

<h4>list_session_notifications($delete = TRUE)</h4>
<p>Return a list of all pending notifications for the current session.</p>
<h4>list_all_notifications($delete = TRUE)</h4>
<p>Return a list of all notifications.</p>
<h3>jQuery Plugin API</h3>
<p>The jQuery code included in this plugin is implemented as a jQuery plugin with the class name of “jQuery.notification”.</p>
<p>The functions supported by this class are:</p>
<h4>notification(message, type, isSticky, pluginurl)</h4>
<p>–<strong>message</strong> (required) may be a string or an object.</p>
<p>If it is a string, the string is the notification text to be displayed.<br />
If it is an object, the object may contain properties corresponding to any of the options supported by the jQuery.options method.</p>
<p>_<strong>type</strong> (optional) indicates the notification type as either a string or an integer. If missing, type will use the current option.type value.</p>
<p>_<strong>isSticky</strong> (optional) indicates whether the notification is sticky. If missing, isSticky will use the value from msgType.</p>
<p>_<strong>pluginurl</strong> (optional) indicates the url to be called by this function to communicate with the server. If missing, the code will search for a hidden field named #hid_plugin_url.</p>
<p>Examples:</p>
<pre><code>    jQuery.notification('This is a notification',3,true);

    jQuery.notification({ notification: 'This is a notification', 
            type: "data", 
            sticky: true, 
            queue: false });

    class: '',          //  jGrowl class that styles this message
    clear: true,        //  Delete saved messages after showing them
    showOnConsole: true,//  Show a copy of the message on the console.log
    glue: 'after',      //  jGrowl property that controls order of displaying messages

    notification: ''    //  Message can be included with options
