Date appearance in text box

i started a question on support forum of pum
i do not know why the code ( get_the_date) does not take the publishing date of the popup but only from the page where it is opened.

Now let’s check the feasibility first, and then do the styling.
if you takte this as shortcode :

function shortcode_for_publishing_date_of_posts(){
 	return get_the_date( 'd.m.Y', get_the_ID($post->ID) );
}
add_shortcode( 'post_published', 'shortcode_for_publishing_date_of_posts' );

but it is alway the publishing date of the page where the popup is placed

but there must be a possibility, because when I look at a blog page from Enfold, there is also the publishing time of the single blog page displayed and not that of the blog page.
I hope a mod can answer this question, because I have to take care of my business now.

here is the solution to it:

remove the shortcode function so that you only have on child-theme functions.php:

// this is now the code to insert the popup publishing date - 
// all credits goes to a guy that helped me from wp-popupmaker : Mark Chaves !
function add_date_time_popup_content( $content ) {
	if ( ! function_exists( 'pum_get_popup_id' ) ) return;
	$popup_id = pum_get_popup_id();
	return "<p class='date-published'>" . get_the_date( 'd.m.Y' , $popup_id ) . "</p>" . $content  ;
}
add_filter( 'pum_popup_content', 'add_date_time_popup_content' );

//-----------------
// this is the known script
function show_date_of_popup(){
?>
<script type="text/javascript">	
(function($) {
	$(document).ready(function(){ 	  
		$('.pum-trigger').each(function() {
			var pumPopup = $('.pum').css('display');
			var trigger_name = $(this).attr('class').split(' ')[0];
			var publishingDate = $(this).closest('#top').find('#'+trigger_name+' .date-published').text();
			var date_published = $('<span class="puplished">'+publishingDate+'</span>');
			$(this).append(date_published);	
		});
	});	
})(jQuery);	       
</script>
<?php
}
add_action('wp_footer', 'show_date_of_popup', 9999);

yes sorry – on my testinstallation i have first the pum-trigger class than the id
so i corrected the second code to split on [0]
( var trigger_name = $(this).attr('class').split(' ')[0]; this is different to my installation – you had to take the first part of the class list )

replace it

on your triggers : you have the classes ( f.e.)
popmake-21659 pum-trigger

on my testinstallation i would have:
pum-trigger popmake-21659

we need that popmake-21659

so just replace the whole code by:

// this is now the code to insert the popup publishing date - 
// all credits goes to a guy that helped me from wp-popupmaker : Mark Chaves !
function add_date_time_popup_content( $content ) {
	if ( ! function_exists( 'pum_get_popup_id' ) ) return;
	$popup_id = pum_get_popup_id();
	return "<p class='date-published'>" . get_the_date( 'd.m.Y' , $popup_id ) . "</p>" . $content  ;
}
add_filter( 'pum_popup_content', 'add_date_time_popup_content' );

//-----------------
// this is the known script
function show_date_of_popup(){
?>
<script type="text/javascript">	
(function($) {
	$(document).ready(function(){ 	  
		$('.pum-trigger').each(function() {
			var pumPopup = $('.pum').css('display');
			var trigger_name = $(this).attr('class').split(' ')[0];
			var publishingDate = $(this).closest('#top').find('#'+trigger_name+' .date-published').text();
			var date_published = $('<span class="puplished">'+publishingDate+'</span>');
			$(this).append(date_published);	
		});
	});	
})(jQuery);	       
</script>
<?php
}
add_action('wp_footer', 'show_date_of_popup', 9999);

ok – you got it now
But – now you have to remove in your popups the shortcode :

<span class="date-published">[post_published]</span>

if you do not want to show the published date in the popups content – you can hide it there.
or you can shift it to the bottom of the popup content.

But think of – you want the publishing date of the popup to show – i can see now different manual dates on that:

https://kriesi.at/support/topic/date-appearance-in-text-box/page/2/#post-1301398

if you like to have some binding words in that date do it this way:
The backslash will show the code that it does not stand for the day but to have text here

'l \d. d.m.Y'

we can surround the weekday by some html with a class. Those extra letters had to be escaped.

Replace the whole code with:

function add_date_time_popup_content( $content ) {
	if ( ! function_exists( 'pum_get_popup_id' ) ) return;
	$popup_id = pum_get_popup_id();
	return "<p class='date-published'>" . get_the_date( '\<\s\p\a\n \c\l\a\s\s\=\"\w\e\e\k\d\a\y\"\> l \<\/\s\p\a\n\> \d. d.m.Y' , $popup_id ) . "</p>" . $content  ;
}
add_filter( 'pum_popup_content', 'add_date_time_popup_content' );

function show_date_of_popup(){
?>
<script type="text/javascript">	
(function($) {
	$(document).ready(function(){ 	  
		$('.pum-trigger').each(function() {
			var pumPopup = $('.pum').css('display');
			var trigger_name = $(this).attr('class').split(' ')[0];
			var publishingDate = $(this).closest('#top').find('#'+trigger_name+' .date-published').html();
			var date_published = $('<span class="puplished">'+publishingDate+'</span>');
			$(this).append(date_published);	
		});
	});	
})(jQuery);	       
</script>
<?php
}
add_action('wp_footer', 'show_date_of_popup', 9999);

and put this to quick css:

.puplished .weekday,
.date-published .weekday {
	text-transform: capitalize;
}
