Description

WP Last Modified Info: the Ultimate Last Modified plugin for WordPress

Most WordPress themes usually show the date when a post was last published. This is fine for most blogs and static websites. However, WordPress is also used by websites where old articles are regularly updated. This last updated date and time is important information for those publications. The most common example is news websites. They often update old stories to show new developments, add corrections, or media files. If they only added the published date, then their users would miss those updates.

Many popular blogs and websites don't show any date on their articles. This is a bad practice and you should never remove dates from your blog posts.

So now it is possible to add last modified / updated info on your wordpress posts and pages. Just install and activate this and configuaration is very easy.

Displays/echos the last modified info:

<?php if ( function_exists( 'the_last_modified_info' ) ) { the_last_modified_info(); } ?>

Published date is equal to modified date. What is the solution?

Sometimes you may want to show last modified date only. For that reason, post published date and modified date would be the same and the last modified date will still appear on post/pages even if it’s the same as the published date. In that case, you can set a time difference(ex. 1 day i.e. 24 hours) between post published date and modified date via plugin settings gap option.

Post detailed information about the issue in the support forum and I will work to fix it.

Posts list messed up

Look at the title column. When disabling "Last Modified", everything is back to normal.

Using Elementor Blog Object - Last Modified info not available

Sayan,

We're using your plugin with Elementor & noticing when using Elementor's built in blog object that we're unable to choose your last modified info as a metadata object. ie: display your date/time under our blog post. I see in the support forum we are not alone. Any likelyhood you might be able to remedy that in the near future? I'm happy to collaborate so you can see exactly what I mean..

Zoom or screen grabs are available of what I see in Elementor.. just ask! Thanks!

Frontend posts sorted by date modified

We have the settings like so:

Despite this, frontend posts are being sorted by post_modified instead of post_date.

The workaround was to go to the settings page and click Save Settings, which forced a save of the settings.

I suspect the bug is here:

if ( ! $this->is_equal( 'default_sort_order', 'default' ) ) {
	if ( ! is_admin() && $query->is_main_query() ) {
	    if ( $query->is_home() || $query->is_category() || $query->is_tag() ) {
	    	$query->set( 'orderby', 'modified' );
	    	$query->set( 'order', $front_order );
		}
	}
}

If $this->get_data( 'lmt_' . $name ) returns an empty string, it says "oh, that's not the default, let's sort by date modified".

Adding a nonempty check would probably fix it:

if ( $this->get_data( 'lmt_default_sort_order' ) && ! $this->is_equal( 'default_sort_order', 'default' ) ) {

Possibility to show published date as well

Detail Requirement:

• To be used with shortcode
• Show 'Published On Dec 19, 2019' if not updated or updated within set gap. 'Published On' being the default text.
• Otherwise show 'Updated On Dec 19, 2019'. 'Updated On' is the default text.

I think it is already possible for themes whose template is supported, WP Last Modified Info replaces the existing post date that comes from the theme.

I need to insert it via shortcode, it can be two shortcodes (published & modified) but only one should be visible based on settings.

Update:
I made it work via replacement Text or HTML Replacement. Minor problem I noticed is that it requires to match the exact number of spaces as well. May be we can clean up a bit on that.
Of course, placing publish date from plugin itself would have been much elegant.

How to replace post published date with post modified info?

Hi, this is a nice plugin but I would really like to get the info inline with the other post information (author, category, comments number, etc.). Is this possible?

I read that it "Allows you to replace post published date with post modified info." so that suggests it should be possible. But I can't see how in the Settings.

Imporvements

Code Improvements:

1. Allow Toogle Disable Update Option for all post types and posts with future date.
2. Optimize codebase.

Edit date

I have noticed that displaying the administration panel in a language other than English, despite manually changing the post modification date and clicking the "Update" button, the edited date still displays as January instead of the month I have set. Additionally, the date format is incorrect, showing as month - day - year instead of year - month - day.

Load Elementor CSS only if the plugin is active
