I want to display the last update date of a post in WordPress, i can find this code and i must put it in function.php
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' );
It's working but the problem that i also have update date displayed on pages, portfolios, ....
How can i limit the display of updated date just on post for the blog ?
Thanks for helping.
Just add a condition to check the post type:
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 && is_singular('post')) {
$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' );
is_singular() queries for a single post and takes the post type as an argument.

I'm using the following function for an excerpt in Wordpress.
<?php
// Excerpt - end of sentence
function custom_wp_trim_excerpt($text) {
$raw_excerpt = $text;
if ('' == $text) {
// Retrieve the post content.
$text = get_the_content('');
// Delete all shortcode tags from the content.
$text = strip_shortcodes($text);
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$allowed_tags = '<i>,<strong>';
$text = strip_tags($text, $allowed_tags);
$excerpt_word_count = 40;
$excerpt_length = apply_filters('excerpt_length', $excerpt_word_count);
$excerpt_end = '...' . '<div class="read-more"><a class="button" href="' . get_permalink($post->ID) . '">' . 'Read More' . '</a></div>';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
$words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
if (count($words) > $excerpt_length) {
array_pop($words);
$text = implode(' ', $words);
$text = $text . $excerpt_more;
}
else {
$text = implode(' ', $words);
}
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
I want to add a second word count to use on the blog page. The above word count is being used on the front page. Advice, please? Thanks.
Try this piece of code
function custom_wp_trim_excerpt($text) {
if ( is_front_page() || is_home() ) {
// Excerpt for front page or home page
} else {
// Excerpt for rest of the site
}
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
By using this piece of code you have more control over the excerpt that is outputted on different pages.
If that worked mark your question as solved.

How can i do it using mysql?
Thanks in advance!
you don't need to do it in mysql, you can use a hook.
Something like that:
function append_content($content) {
global $post;
if (in_category( 5, $post )) {
$original = $content;
$content = "<div class=\"ikaz\">";
$content .= "hello all";
$content .= "</div>";
$content .= $original;
return $content;
}
}
add_filter( 'append_content', 'like_content' );

Hey guys so I ran into the same problem and managed to solve it incorporating your answers into one.
The function that does all the processing is changed so that is counts all the paragraphs created by the explode method. Then another if statement is added to evaluate when you are at the desired location.
function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
$closing_p = '</p>';
$paragraphs = explode( $closing_p, $content );
$last_paragraph_index = count($paragraphs);
foreach ($paragraphs as $index => $paragraph) {
if ( trim( $paragraph ) ) {
$paragraphs[$index] .= $closing_p;
}
if ( $paragraph_id == $index + 1 ) {
$paragraphs[$index] .= $insertion;
}
else if( $last_paragraph_index + $paragraph_id == $index + 1){
$paragraphs[$index] .= $insertion;
}
}
return implode( '', $paragraphs );
}
in order to use the new functionality you must call it with a negative number.
Think of the function this way, if you want to go from the top of the content you use a positive number, if you want to go from the bottom of the content you use a negative number.
Remember that even though the evaluation is for your decided spot such as before the last paragraph the condition that adds to the array uses the index which we all know is zero based.
This just means that to get after paragraph 1 you must use the number 2 when calling the function and to get to before the last paragraph you have to use -2 and so on.
Here is my example to add the a read the next post if it exists to the article
add_filter( 'the_content', 'prefix_insert_next_article_banner' );
function prefix_insert_next_article_banner( $content ) {
if ( is_single() && ! is_admin() && get_next_post_link() ) {
$next_banner = '<div class="next-banner"> <span> Read Next </span>';
$next_banner .= ' ' . get_the_title(get_adjacent_post(false,'',false)) .' ';
$next_banner .= '</div>';
return prefix_insert_after_paragraph( $next_banner, -2, $content );
}
return $content;
}
How to limit the excerpt length by paragraph, not word/char count? For example, excerpt shows only first two paragraphs, no matter how long the paragraphs are.
Thanks in advance.
Here is a function that keeps HTML tags in tact, adds a "Read More" link at the end of the excerpt and trims the excerpt after the first paragraph.
if ( ! function_exists( 'wpse0001_custom_wp_trim_excerpt' ) ) :
function wpse0001_custom_wp_trim_excerpt($wpse0001_excerpt) {
global $post;
$raw_excerpt = $wpse0001_excerpt;
if ( '' == $wpse0001_excerpt ) {
$wpse0001_excerpt = get_the_content('');
$wpse0001_excerpt = strip_shortcodes( $wpse0001_excerpt );
$wpse0001_excerpt = apply_filters('the_content', $wpse0001_excerpt);
// Here we choose how many paragraphs do we want to cutthe excerpt at, This part thanks to Clément Malet
$wpse0001_excerpt = "<p>$wpse0001_excerpt</p>";
$wanted_number_of_paragraph = 2;
$tmp = explode ('</p>', $wpse0001_excerpt);
for ($i = 0; $i < $wanted_number_of_paragraph; ++$i) {
if (isset($tmp[$i]) && $tmp[$i] != '') {
$tmp_to_add[$i] = $tmp[$i];
}
}
$wpse0001_excerpt = implode('</p>', $tmp_to_add) . '</p>';
$wpse0001_excerpt = str_replace(']]>', ']]>', $wpse0001_excerpt);
$excerpt_end = ' ' . ' » ' . sprintf(__( 'Read more about: %s »', 'pietergoosen' ), get_the_title()) . '';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
//$pos = strrpos($wpse0001_excerpt, '</');
//if ($pos !== false)
// Inside last HTML tag
//$wpse0001_excerpt = substr_replace($wpse0001_excerpt, $excerpt_end, $pos, 0);
//else
// After the content
$wpse0001_excerpt .= $excerpt_end;
return $wpse0001_excerpt;
}
return apply_filters('wpse0001_custom_wp_trim_excerpt', $wpse0001_excerpt, $raw_excerpt);
}
endif;
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'wpse0001_custom_wp_trim_excerpt');
EDIT
Thanks to the help from #ClementMalet, I was able to tweak my function to make you choose the amount of paragraphs where you want to cut the excerpt. Please check his great answer here
Hello i have a website and a blog, i want to display my self hosted wordpress blog on my website.
I want to show only 3 post on my website.
I want to automatically check for any new post everytime when i reload my website, so that the recent three gets displayed only.
I want to show the complete title of my wordpress blogpost but specific letters of description.
Also the description should end up with a word not some piece of non-dictionary word ending with "..."
How this can be done, i have heard that it can be done through RSS.
Can somebody help me?
To accomplish this you need to read the RSS of the blog, from RSS you need to read the Title and the description, after reading the whole description and title you need to trim the description to your desired number of letters. After that you need to check weather the description last word has been completed or not and then you need to remove a the last word if not completed and put the "...".
First we will make a script to trim the description and to put "..." in last:-
<?php
global $text, $maxchar, $end;
function substrwords($text, $maxchar, $end='...') {
if (strlen($text) > $maxchar || $text == '') {
$words = preg_split('/\s/', $text);
$output = '';
$i = 0;
while (1) {
$length = strlen($output)+strlen($words[$i]);
if ($length > $maxchar) {
break;
}
else {
$output .= " " . $words[$i];
++$i;
}
}
$output .= $end;
}
else {
$output = $text;
}
return $output;
}
Now we will define the variables in which we store the values:-
$xml=("http://your-blog-path/rss/");
global $item_title, $item_link, $item_description;
$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
$x=$xmlDoc->getElementsByTagName('item');
Now, we will make an array and store values in it. I am only taking 3 because you have asked it the way. You can change it to anything (The number of post you want to show, put that in the loop)
for ($i=0; $i<3; $i++)
{
$item_title[$i] = $x->item($i)->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;
$item_link[$i] = $x->item($i)->getElementsByTagName('link')->item(0)->childNodes->item(0)->nodeValue;
$item_description[$i] = $x->item($i)->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;
}
?>
Now echo all these values, Link is the value where your user will click and he will be taken to your blog:-
FIRST RECENT POST:
<?php echo $item_title[0]; ?>
<?php echo substrwords($item_description[0],70); ?>
SECOND RECENT POST:
<?php echo $item_title[1]; ?>
<?php echo substrwords($item_description[1],70); ?>
THIRD RECENT POST:
<?php echo $item_title[2]; ?>
<?php echo substrwords($item_description[2],70); ?>
Hope this can solve your problem. By the way Nice question.
Click here for the original documentation on displaying RSS feeds with PHP.
Django Anonymous's substrwords function is being used to trim the description and to insert the ... at the end of the description if the it passes the $maxchar value.
Full Code:
blog.php
<?php
global $text, $maxchar, $end;
function substrwords($text, $maxchar, $end='...') {
if (strlen($text) > $maxchar || $text == '') {
$words = preg_split('/\s/', $text);
$output = '';
$i = 0;
while (1) {
$length = strlen($output)+strlen($words[$i]);
if ($length > $maxchar) {
break;
} else {
$output .= " " . $words[$i];
++$i;
}
}
$output .= $end;
} else {
$output = $text;
}
return $output;
}
$rss = new DOMDocument();
$rss->load('http://wordpress.org/news/feed/'); // <-- Change feed to your site
$feed = array();
foreach ($rss->getElementsByTagName('item') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
);
array_push($feed, $item);
}
$limit = 3; // <-- Change the number of posts shown
for ($x=0; $x<$limit; $x++) {
$title = str_replace(' & ', ' & ', $feed[$x]['title']);
$link = $feed[$x]['link'];
$description = $feed[$x]['desc'];
$description = substrwords($description, 100);
$date = date('l F d, Y', strtotime($feed[$x]['date']));
echo '<p><strong>'.$title.'</strong><br />';
echo '<small><em>Posted on '.$date.'</em></small></p>';
echo '<p>'.$description.'</p>';
}
?>
You can easily put this in a separate PHP file (blog.php) and call it inside your actual page.
Example:
social.php
<h3>Latest blog post:</h3>
<?php require 'blog.php' ?>
Also, this code is plug-n-play friendly.
Why not use the Wordpress REST API to retrieve posts -
API URL is : https://public-api.wordpress.com/rest/v1/sites/$site/posts/
where $site is the site id of your wordpress blog
or else simply use this plugin -
