Session messages provides support for displaying information to the user in a div element styled using Bootstrap alert classes. Examples are shown below:

When using with PHP you must first call the addMessage function form the Session class. An example for how to perform this task is shown below:

Session::addMessage('success', 'Contact has been deleted');

The result of performing the action is shown below in Figure 1.

Note that the user can close each message by clicking on the x button.

This same action can be completed using jQuery. The only difference is a popup message appears at the bottom of the screen with the message and disappears after 5 seconds. An example from where we use this to delete an image is shown below:

function deleteImage(image_id) {
    if(confirm("Are you sure?  This cannot be undone!")) {
        jQuery.ajax({
            url : '/admindashboard/deleteImage',
            method: "POST",
            data : {image_id : image_id},
            success: function(resp) {
                if(resp.success) {
                    jQuery('#image_'+resp.model_id).remove();
                    updateSort();
                    alertMsg('Image Deleted.');
                }
            } 
        });
    }
}

The result of calling this function is shown below in Figure 2.
