So I have a custom PHP page in Wordpress that displays some content:
<? while(have_posts() ) : the_post(); ?>
<?the_content();?>
<? endwhile; ?>
I need to display the list of news related with this content, so I wrote a shortcode for that:
function generate_program_news(){
$news_args = array( 'posts_per_page' => 5, 'cat' => 4);
$news_query = new WP_Query($news_args);
$news_data;
while( $news_query->have_posts() ) {
$news_date = get_permalink();
$news_title = the_title();
$news_data = "<a>" .$news_date. ": " .$news_title. "</a>";
}
wp_reset_postdata();
return $news_data;
}
add_shortcode('program_news','generate_program_news');
But when I add [program_news] shortcode and try to access the page I used it in, the entire website dies off until I have the OpenServer rebooted. What am I doing wrong?
while( $news_query->have_posts() )
you must type
$news_query->the_post();

I want to display Posts order by Last updated on the home page, how to right function for it and where to paste that function in wordpress?
Create your plugin and paste this function in plugin file.
function wpb_lastupdated_posts()
{
// Query Arguments
$lastupdated_args = array(
'orderby' => 'modified',
'ignore_sticky_posts' => '1'
);
//Loop to display 5 recently updated posts
$lastupdated_loop = new WP_Query( $lastupdated_args );
$counter = 1;
$string .= '<ul>';
while( $lastupdated_loop->have_posts() && $counter < 5 ) : $lastupdated_loop->the_post();
$string .= '<li> ' .get_the_title( $lastupdated_loop->post->ID ) . ' ( '. get_the_modified_date() .') </li>';
$counter++;
endwhile;
$string .= '</ul>';
return $string;
wp_reset_postdata();
}
//add a shortcode
add_shortcode('lastupdated-posts', 'wpb_lastupdated_posts');
use this shortcode : [lastupdated-posts]
There are 3 ways to do this
add this code in the functions.php file
function shortcode_latest_homepage_posts(){
$lquery = new WP_Query(array('order' => 'DESC'));
if($lquery->have_posts()){
while($lquery->have_posts()){
$lquery->the_post();
the_title();
the_content();
}
}
wp_reset_postdata();
}
add_shortcode('latest_posts', 'shortcode_latest_homepage_posts');
and add simply this [latest_posts] shortcode in the page editor that you have assign for the front page in cms
OR
add this code in functions.php
function latest_homepage_posts(){
$lquery = new WP_Query(array('order' => 'DESC'));
if($lquery->have_posts()){
while($lquery->have_posts()){
$lquery->the_post();
the_title();
the_content();
}
}
wp_reset_postdata();
}
add_action('latest_post', 'latest_homepage_posts');
and add this code at the place where you want to show the post in the template that assign for or made for a home page like home.php or front-page.php
<?php do_action('latest_post');?>
OR
3. simply add this code at the place where you want to show the post in the template that assign for or made for a home page like home.php or front-page.php
<?php
$lquery = new WP_Query(array('order' => 'DESC'));
if($lquery->have_posts()){
while($lquery->have_posts()){
$lquery->the_post();
the_title();
the_content();
}
}
wp_reset_postdata();
?>
I just started with a wordpress tutorial series and one of the first things it does was make a simple "the loop", to print the title and description of all of the posts. When I did it though, it prints the name and description of the home page.
<?php
if ( have_posts() )
{
while ( have_posts() )
{
the_post();
the_title('<h2><a href="the_permalink();"','</a></h2>');
the_content();
// Post Content here
//
} // end while
} // end if
?>
I cannot figure out why it prints the home page information instead of post info.
To display wordpress posts on any page , you need to pass the arguments as the following in the WP_Query and then loop them via object.
// The Query
$the_query = new WP_Query( array( 'post_type' => 'post','posts_per_page' => -1 ) );
// The Loop
if ( $the_query->have_posts() ) {
echo '<ul>';
while ( $the_query->have_posts() ) {
$the_query->the_post();
echo '<li>' . get_the_title() . '</li>';
}
echo '</ul>';
/* Restore original Post Data */
wp_reset_postdata();
} else {
// no posts found
}
Trying to write my first short-code that displays all post-titles in a specific Category. But it is not displaying the actual results, just the short code.
Here is what I have so far in my child theme's functions.php file:
function posts_in_cat() {
echo '<ul>';
query_posts('cat=3'); while (have_posts()) : the_post();
echo ('<li>' . the_title() . '</li>');
endwhile;
wp_reset_query();
echo '</ul>';
}
add_shortcode( 'display_posts_in_cat', 'posts_in_cat' );
And then I am calling the short code, like so [display_posts_in_cat].
Any help would be greatly appreciated as I try and learn this.
EDIT: I have gotten it to display but the link itself is being echo-ed in front of the title in text. Also, it is not displaying more than 10 of the titles and I want it to display them all. Any ideas...?? Thanks.
First and foremost, avoid using query_posts() – it's inefficient. Check out this SO answer for the skinny.
Additionally, shortcodes shouldn't make use of echo statements. Shortcodes only return text. Put simply, WordPress has PHP internally that says "when this specific shortcode is entered into the editor, replace it with the text returned from this function." Using echo causes you to immediately print those statements to the screen, rather than returning to WordPress so that it can continue with its regular process. More on the WP Codex.
And, finally, shortcode functions require $atts as a parameter.
So, with all that said, here's how I would rewrite your function:
<?php
function posts_in_cat( $atts ) {
$atts = shortcode_atts( array(
'cat' => '',
), $atts );
if ( empty( $atts['cat'] ) ) {
// If category provided, exit early
return;
}
$args = array(
'category' => $atts['cat'],
// Disable pagination
'posts_per_page' => -1
);
$posts_list = get_posts( $args );
if ( empty( $posts_list) ) {
// If no posts, exit early
return;
}
$opening_tag = '<ul>';
$closing_tag = '</ul>';
$post_content = '';
foreach ( $posts_list as $post_cat ) {
$post_content .= '<li>' . esc_html( get_the_title( $post_cat->ID ) ) . '</li>';
}
return $opening_tag . $post_content . $closing_tag;
}
add_shortcode( 'display_posts_in_cat', 'posts_in_cat' );
I'm just adding all of the content you were echoing into a handful of variables, and then returning them, concatenated, at the end. Also, I added in an if statement to exit early if there aren't any posts in the category. That way you don't have an empty <ul> element cluttering up the page.
I've also escaped the outputs, which you can read about on the Codex.
Please try this:
function posts_in_cat() { ?>
<ul class="posts">
<?php query_posts('cat=3&showposts=50'); while (have_posts()) : the_post();
?>
<li><a href='<?php the_permalink() ?>'><?php the_title(); ?></a></li>
<?php endwhile; ?>
<?php wp_reset_query(); ?>
</ul>
<?php
}
add_shortcode( 'display_posts_in_cat', 'posts_in_cat' );
Hellow everyone!
I am showing blog of posts in additional wp template and everything works fine, but I've made some kind of gallery from it, and I don't need to show anything except gallery and title.
Inside posts I have this:
[gallery ids="1618,...,1634"]
<h2>...</h2>
<p>...</p>
text without format, etc.
As you can see, I am using a gallery shortcode. I need it to be shown, but all other content to be excluded from the loop.
Really appreciate your help in this question...
My template code:
<?php
/*
* Template name: Блог
*/
$current_page = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'posts_per_page' => 9,
'paged' => $current_page,
'cat' => 8
);
query_posts( $args );
$wp_query->is_archive = true;
$wp_query->is_home = false;
while(have_posts()): the_post();
?>
<div class="foto_posts">
<?php the_content() ?>
<?php echo '' . get_the_title() . '';?>
</div>
<?php
endwhile;
if(function_exists('page_navi_slider')) page_navi_slider();
try to replace <?php the_content() ?> to <?php the_title() ?>
if you just want to show gallery shortcode try this
replace
<?php the_content() ?>
to
$pattern = get_shortcode_regex();
preg_match('/'.$pattern.'/s', $post->post_content, $matches);
if (is_array($matches) && $matches[2] == 'gallery') {
$shortcode = $matches[0];
echo do_shortcode($shortcode);
}
Try this for getting galleries and videos use the get_post_meta_key()
<?php get_post_meta($post_id,'key_name',1);?>
If it returns an array then traverse that array to get the images link and video links
add_shortcode('gallery', 'gallery_shortcode_fancybox');
function gallery_shortcode_fancybox($attr) {
$attachment_ids = explode(',',$attr['ids']);
$args = array(
'post__in' => $attachment_ids,
//'cat' => 8 if category needs to be shown pass it in shortcode , same as ids
);
$gallery_posts = query_posts( $args );
foreach ($gallery_posts as $key => $value) {
//do the stuff here
echo '<h2>'. $value->post_title;'</h2>';
$feat_image = wp_get_attachment_url( get_post_thumbnail_id($value->ID);
echo '<p><img src="'.$feat_image.'" ></p>';
}
}
I've developed custom theme from scratch with _S starter theme. I'm having issue getting Wordpress next posts via ajax request on click on read more button. I've tried many articles specifically the following articles, but no luck.
Reference Links:
Load More Posts Ajax Button in Wordpress
Load Next WordPress Posts With AJAX
Load Old WordPress Posts on the Same Page with AJAX
I've tried going with above custom loops and adding custom functions with jquery script but it don't work somehow.
Here is loop code example below:
Loop in index.php
<?php query_posts('showposts=5'); if (have_posts()) : while (have_posts()) : the_post(); ?>
<article class="post-item">
<h2><?php the_title(); ?></h2>
<?php the_excerpt(); ?>
</article>
<?php endwhile; ?>
<?php else : ?>
<h2>Sorry no posts are created yet.</h2>
<p>Please create some posts to see it in action.</p>
<?php endif; wp_reset_query(); ?>
<button class="load-more-btn">Load More</button>
I'm messing with this issue for over 4-5 days, so any one can help me out with this issue with working solution will be highly appreciable.
Thanks in advance.
I maybe have a solution for your.
First be sure to have a script enqueue in your theme
wp_enqueue_script('your_js_hanlde', get_template_directory_uri() . '/js/your_js_hanlde.js', array('jquery'), '1.0.0', true );
then localize add a function to add a js var in your dom
wp_localize_script('your_js_hanlde', 'ajaxurl', admin_url( 'admin-ajax.php' ) );
In your js, add an event on 'click' on your 'Load More' button
Pass an action name and the count of article you have in your dom, the response add the content before your button 'load more'
$("#load_more").click(function()
{
$.post(ajaxurl,
{
'action': 'your_load_more',
'count': $("article.post-item").length
},
function(response)
{
var posts = JSON.parse(response);
for( var i = 0; i < posts.length; i++ )
{
if( posts[i] == "0" )
$("#load_more").fadeOut();
else
$("#load_more").before(posts[i]);
}
});
});
create a function in your functions.php
function your_load_more()
{
$count = $_POST["count"];
$cpt = 1;
$args = array(
'posts_per_page' => -1,
'post_type' => 'post', // change the post type if you use a custom post type
'post_status' => 'publish',
);
$articles = new WP_Query( $args );
$ar_posts = array();
if( $articles->have_posts() )
{
while( $articles->have_posts() )
{
$articles->the_post();
$one_post = "";
if( $cpt > $count && $cpt < $count+6 )
{
$one_post .= "<article id='" . get_the_id() . "' class='post-item'>";
$one_post .= "<h3>" . get_the_title() . "</h3>";
$one_post .= "</article>";
$ar_posts[] = $one_post;
if( $cpt == $articles->found_posts )
$ar_posts[] = "0";
}
$cpt++;
}
}
echo json_encode($ar_posts);
die();
}
add_action( 'wp_ajax_your_load_more', 'your_load_more' );
add_action( 'wp_ajax_nopriv_your_load_more', 'your_load_more' );
It work for me.
I hope that help you.
