iPROS24 Notices – Advanced usage and examples

Notes on advanced usage of iPROS24 Notices plugin. Ready-to-go examples.

Adding custom conditions

You may add any number of custom conditions in Dashboard › Settings › Notices. Condition names may contain alphanumeric characters, spaces and underscores and start with a letter or underscore.

All custom conditions are false by default. You need to add a filter for a server-side condition and set a variable for a client-side one.

Examples

Let’s add a server-side condition which is true when a user is logged in and is an administrator.

• Go to Dashboard › Settings › Notices.
• Enter Is admin condition name in Custom server-side conditions section.
• Click Add.

The name of the filter appears in WordPress filter column.

• Add the following lines to Server-side script:

function ipros24_notices_is_admin ()	{

	global $current_user;

	return in_array ("administrator", $current_user->roles);
}

add_filter ('ipros24_notices_is_admin', 'ipros24_notices_is_admin');

• Click Save Changes.

Done. Now we have a condition we can use e.g. to preview notices on a production site.

Now let’s add a client-side condition which is true when it’s Christmas in user’s timezone.

• Go to Dashboard › Settings › Notices.
• Enter Is Xmas condition name in Custom client-side conditions section.
• Click Add.

The name of the variable appears in JavaScript variable column.

• Add the following lines to Client-side script:

$ (window).on ("ipros24-notices-filter", function ()	{

	var today = new Date ();

	ipros24_notices.is_xmas = (today.getMonth () == 11 &&
		today.getDate () == 25);
});

• Click Save Changes.

We have a condition we can use to greet our visitors on a Christmas day.

Creating notices

Go to Dashboard › Notices and Add New notice. Notices are implemented as a custom post type so adding a notice is not much different from adding a post.

After you finish editing select the conditions to be met in Notice Attributes box.

NB: Use server-side conditions to filter sensitive notices.

Examples

Let’s add a warning some features of the site won’t work if cookies are disabled in user’s browser.

• Go to Dashboard › Notices and click Add New.
• Enter the notice. E.g. You have to enable cookies for this site to work properly.
• Select Cookies enabled › False in Notice Attributes box.
• Click Update.

Done.

Personalising the notices

There’s a shortcode you can use to personalise your notices. It will be replaced with the user’s display name or the text between the tags if the user hasn’t logged in yet.

Examples

Merry Xmas, [ipros24_user]friend[/ipros24_user]!

Notes on security

Only administrators of single site installations have the capability to edit server-side scripts. In multisite only the Super Admin has this capability. To completely disable server-side scripts editing add to wp-config.php:

define ('ALLOW_EDIT_SERVER_SIDE_SCRIPTS', FALSE);
