This simple WordPress plugin displays a message in any single post that has been published x years ago from the current time or earlier. The default time to count back is 1 year. Minimal post age as well as message text, HTML, and CSS are fully customizable via settings.

Languages

• English (en_US) (default)
• German (de_DE)
• Formal German (de_DE_formal)

I can’t find the settings page, where is it?

It’s right there, under General Settings in your admin menu. Configurable settings are:

• Activate Message: By default, no message will show up on your website until you activate it here.
• Minimal Post Age: Set a number of years for posts to be considered aged. Default: 1.
• Message Heading: Heading text. Default: The times, they are a-changin’. (Dylan, google him.)
• Message Body (Singular): Singular form of the message text, for 1 year-old posts.
• Message Body (Plural): Plural form of the message text, for 2+ year-old posts.
• Message Class Attribute: CSS class name(s) applied upon the message’s wrapping <div>.
• Message HTML: HTML template for the message. You can completely control its output via this field if you want, or use placeholders for heading and text.
• Message CSS: Customize the visual styling of your message right here. Or not.

Can I disable default styles?

Sure, just empty the CSS field and no styles shall be applied. If you want to add styles to your theme instead, this might get you started:

/* Default styles */
.aged-content-message {
    background: #f7f7f7;
    border-left: 5px solid #f39c12;
    font-family: inherit;
    font-size: .875rem;
    line-height: 1.5;
    margin: 1.5rem 0;
    padding: 1.5rem;
}
.aged-content-message h5 {
    font-family: inherit;
    font-size: .8125rem;
    font-weight: bold;
    line-height: 2;
    margin: 0;
    padding: 0;
    text-transform: uppercase;
}
.aged-content-message p {
    margin: 0;
    padding: 0;
}

Where have all the filters gone?

You can still use those good old filters from v1.3, like for this conditional handbrake that doesn’t have a setting (yet):

/* Set condition for displaying message to include pages. */
function yourprefix_aged_content_message__the_content_condition() {
    return ! is_single() && ! is_page();
}
add_action( 'aged_content_message__the_content_condition',
    'yourprefix_aged_content_message__the_content_condition' );
