Using 'last modified' site wide, rather than on specific page/post - wordpress

I want to show some text along the lines of 'This website was last updated on 10/11/2019' - I can find solutions to do this on individual pages and posts, but not something that queries the DB and finds the last update across the site.
I have tried to adapt some wp_query but failed miserably.

you can do it by Two ways:1: You can do it by using This Plugin
2: if you don't want to use this plugin you can edit function.php file add this code there
function wpb_last_updated_date( $content ) {
$u_time = get_the_time('U');
$u_modified_time = get_the_modified_time('U');
if ($u_modified_time >= $u_time + 86400) {
$updated_date = get_the_modified_time('F jS, Y');
$updated_time = get_the_modified_time('h:i a');
$custom_content .= '<p class="last-updated">Last updated on '. $updated_date . ' at '. $updated_time .'</p>';
}
$custom_content .= $content;
return $custom_content;
}
add_filter( 'the_content', 'wpb_last_updated_date' );
This code checks to see if a post’s published date and last modified dates are different. If they are, then it displays last modified date before the post content.
you can add css to make it look better
.last-updated {
font-size: small;
text-transform: uppercase;
background-color: #fffdd4;
}

Display Elementor page to customer in Woocommerce My-Account

I have Woocommerce (Subscriptions) and Elementor. I'm trying to add a page/content within the Myaccount area of Woocommerce - new navigation menu item.
Creating the endpoint and navigation menu bit works without issue. The issue I'm facing is displaying a page created in elementor. One page (also created in elementor) works without issue while the other doesn't.
The page created in elementor is fairly simple that essentially creates 4 columns, 10 rows. Within each row there is button that uses shortcodes to get the button text and url to navigate to when pressed. This is all tested and works without issue when accessing the page directly.
If I use this code
$post = get_post(1114);
$content = apply_filters('the_content', $post->post_content);
echo $content;
on the endpoint to display the page the output is just a list of rows of text showing the table cells from left to right. This only shows the button text (no sign of the URL) and is not formatted in anyway like the page in the elementor editor is (or if accessed directly)
e.g if the table is
H1 H2 H3 H4
R1a R1b R1c R1d
R2a R2b R2d R2d
The display is
H1
H2
H3
R1a
R1b
R1c
R1d
R2a
R2b
R2c
R2d
If I use the below code
$content = \Elementor\Plugin::$instance->frontend->get_builder_content_for_display( 1119);
echo $content;
the table largely displays correctly with all formatting etc. The one thing that isn't working is the button text. Instead of displaying the text returned by shortcode it just displays the shortcode.
I'm sure I'm just missing something that needs to be processed somewhere but I have no idea what it is and the Elementor pages don't give much away unfortunately.
Any help would be appreciated.
EDIT : The correct answer is that there is a dynamic button/dropdown next to the text field that I didn't notice before. Using this you can select shortcode and enter the shortcode details and it will display correctly without having to process manually.
Not sure why it doesn't load correctly as above in the first place but to get around it I did the below. No sure this is the correct way to do this but it works.
$content = \Elementor\Plugin::$instance->frontend->get_builder_content_for_display( 1013 );
$content = process_subswitch_content_for_shortcodes( $content );
echo $content;
The below essentially searches the content returned from the get_builder_content_for_display function for '[subswitch' which is the start of the shortcodes in question (unable to just search for ] as elementor puts other [] in the content).
function process_subswitch_content_for_shortcodes( $content ) {
$keepprocessing = true;
$searchstart_pos = 0;
do {
$startchar_pos = strpos( $content, "[subswitch", $searchstart_pos );
if ( $startchar_pos == false ) {
$keepprocessing = false;
}
$endchar_pos = strpos( $content, "]", $startchar_pos );
$shortcode_request = substr( $content, $startchar_pos, $endchar_pos );
if ( $shortcode_request == false ) {
$keepprocessing = false;
}
$shortcode_content = do_shortcode( $shortcode_request );
$content = str_replace( $shortcode_request, $shortcode_content, $content );
$searchstart_pos = $endchar_pos;
} while ( $keepprocessing );
return $content;
}
I'd of course still like to know the way to load this directly so that it displays without having to process the shortcodes manually so to speak.

hatom-entry errors on the Google snippet test

Almost sure that I'm not the first one that has this question but when I test my (WordPress) page on Google Snippet Test Tool I got hatom-enty errors like:
hatom-feed
hatom-entry:
Fout: At least one field must be set for HatomEntry.
Fout: Missing required field "entry-title".
Fout: Missing required field "updated".
Fout: Missing required hCard "author".
I found some tutorials about this but that is for standard WordPress themes. I'm using Inovado from ThemeForest and I can't figure out in which file I have to edit this data.
Someone familiar with this?
I also got problems with snippet review... Good in testresults but doesn't show up in de Google Search Results. Don't know why...
You can Add this code to the function.php file in your theme's directory and it will solve the problems.
//mod content
function hatom_mod_post_content ($content) {
if ( in_the_loop() && !is_page() ) {
$content = '<span class="entry-content">'.$content.'</span>';
}
return $content;
}
add_filter( 'the_content', 'hatom_mod_post_content');
//add hatom data
function add_mod_hatom_data($content) {
$t = get_the_modified_time('F jS, Y');
$author = get_the_author();
$title = get_the_title();
if(is_single()) {
$content .= '<div class="hatom-extra"><span class="entry-title">'.$title.'</span> was last modified: <span class="updated"> '.$t.'</span> by <span class="author vcard"><span class="fn">'.$author.'</span></span></div>';
}
return $content;
}
add_filter('the_content', 'add_mod_hatom_data');
The code contains 2 functions. The first function will use the WordPress filter hook for “the_content” to add the class of “entry-content” to the article. To add in the other essential hAtom fields, the second function will add a short sentence to the end of your post article, which contains updated time, post title and author, with required microdata.

Including Custom Fields & static text in the_content in WordPress

I am editing a Custom Post Type template, and am using custom fields to enter info into a meta box to be included on the page, as well as include some static default text on all the pages.
I basically need to "chunk" together the post info in the_content along with the static text and some meta box info. Here's what I want:
the_content
static text
meta box 1
more static text
meta box 2
end of the _content
I have plugins that add social buttons before the_content and a signature after the_content so I am trying to figure out how to get all my custom stuff sandwiched in between those.
If I just add the meta boxes i nthe template, they display outside of the_content and the plugins display in unwanted places.
I ended up figuring this out on my own. The solution: using functions.php and add_filter, I had to create a new function to create the default content, and it works great.
here's the general code for anyone interested:
function custom_post_type_default_content($content) {
global $post;
if ($post->post_type == 'your-custom-post-type') {
$content .= '<p> '. get_post_meta( $post->ID, "metabox-1-slug", true ).'
<br />
<p> '. get_post_meta( $post->ID, "metabox-2-slug", true ).'</p>
<p>YOUR TEXT HERE.</p>';
}
add_filter('the_content', 'custom_post_type_default_content', 0);
Note that the zero just near the end controls placement. I have a social media plugin that has a priority of "1", and to get the default content to appear above that I have to make this a priority of "0".
Also note the single apostrophes that open and close the code following $content .=
You basically add whatever you want between those apostrophes, and in this case I am pulling metabox info which have their own apostrophes containing code. It gets confusing!
In other words, your code should be $content .='YOUR CUSTOM CONTENT' and within those apostrophes, add your text, code, etc. The standalone metabox code is '. get_post_meta( $post->ID, "metabox-1-slug", true ).' which is nested inside where the YOUR CUSTOM CONTENT text is.
I am basically explaining this to myself, as these were the things that tripped me up so figured would explain them in detail to help someone else like me. Or me when I have to go look this up again!
Post your single.php here or on pastebin along with the custom field names you're using (& where you want them) and I'll try to help you figure out what you want.
Copy this code to your function.php file.
function content_function_update($content) {
global $wp_query, $post;
if ($post->post_type == 'your-custom-post-type') {
$postid = $wp_query->post->ID;
$value1 = "your value 1";
if($value1 !== '') {
$content = $content . "<br>" . $value1
}
else {
$content = $content;
}
}
return $content;
}
add_filter('the_content', 'content_function_update');
Add any custom content in variables and append it to $content variable.

wordpress: previous_post_link() / next_post_link() placeholder

I am having trouble with the previous_post_link() and next_post_link() functionality. When there is no previous post, the function previous_post_link() does not display a link, likewise for the next_post_link() and the last post. I would like to have a placeholder image so that the design stays consistent.
Currently I have images of green arrows pointing left and right, I would like to place an image of a grey arrow if there are no more posts to go back to.
Is there a way to use the next_post_link()/previous_post_link() functions but not have the link removed.
I also wonder if there is a way for the links to cycle, so that if you come to the most recent post, the next post link would bring you back to the first post.
************ UPDATED ************
Here is the code, based on "silent's" advice (accepted answer) to use get_adjacent_post():
<?php
if(get_adjacent_post(false, '', true)) {
previous_post_link('%link','<img src="larr.gif"/>');
}
else {
echo '<img src="larr2.gif"/>';
};
if(get_adjacent_post(false, '', false)) {
next_post_link('%link','<img src="rarr.gif"/>');
}
else {
echo '<img src="rarr2.gif">';
};
?>
So you can "capture" what next_post_link() and previous_post_link() return using ob_start() and ob_get_clean(), then apply a conditional to it.
Code in practice:
$previous_string = "<-Back";
ob_start(); // start output buffering
previous_post_link("%link", $previous_string);
$previous_link = ob_get_clean(); // stop output buffering and store
if ($previous_link == '') {
echo '<span style="color: #ccc">' . $previous_string . '</span>';
} else {
echo $previous_link;
}
I never try this myself. However, you may refer to this post. It uses get_adjacent_post().
Why cant you try the below?
<div style="float:right"><?php if(get_previous_posts_link()) { previous_posts_link('Newer Entries »'); } else { echo 'No Newer Entries'; } ; ?></div>
Alternatively to display Next and Previous Post Links to Blog post you can easily do that. This is very well explained at globinch.com (WordPress Tips : How to Add Next and Previous Post Links to Blog? )

How to add ads to the end of RSS on wordpress?

I have added a function to functions.php on my theme.
function insertAds($content) {
$content = $content.' add goes here';
return $content;}
add_filter('the_content_feed', 'insertAds');
add_filter('the_excerpt_rss', 'insertAds');
The problem is that I'm having the add displayed under each content, and not at the end of the rss page. How can I fix that?
WordPress doesn’t offer a hook for what you want to do. In which element would you place the ad?
The usual RSS-2-Feed has meta data and items (the content). There is no other element.
See wp-includes/feed-rss2.php for details.
Update
Adjust the following code to your needs and put the file into your plugin directory:
<?php
/*
Plugin Name: Last man adding
Description: Adds content to the last entry of your feed.
Version: 0.1
Author: Thomas Scholz
Author URI: http://toscho.de
Created: 31.03.2010
*/
if ( ! function_exists('ad_feed_content') )
{
function ad_feed_content($content)
{
static $counter = 1;
// We only need to check this once.
static $max = FALSE;
if ( ! $max )
{
$max = get_option('posts_per_rss');
}
if ( $counter < $max )
{
$counter++;
return $content;
}
return $content . <<<MY_ADDITIONAL_CONTENT
<hr />
<p>Place your ad here. Make sure, your feed is still
validating</p>
MY_ADDITIONAL_CONTENT;
}
}
add_filter('the_content_feed', 'ad_feed_content');
add_filter('the_excerpt_rss', 'ad_feed_content');
Is this the effect you had in mind? As you can see, adding content is rather easy. :)
