Counting the posts of a loop (WP_Query)? - wordpress

I tried this way to display NO of post:
<?php
$news_2 = new WP_Query( array (
'post_type'=> 'jobs',
'posts_per_page'=> '10',
'meta_key' => 'status_for_jobs',
'meta_value' => '1'
) );
if ( $news_2->have_posts() ) {
while ( $news_2->have_posts() ) {
$news_2->the_post();
$count = $news_2->post_count;
?>
<li><h3><?php the_title(); ?></h3></li>
<?php
}
}
wp_reset_query();
?>
if the NO of post = 0 i need to display this :-
<?php
$news_2 = new WP_Query( array (
'post_type'=> 'jobs',
'posts_per_page'=> '10',
'meta_key' => 'status_for_jobs',
'meta_value' => '1'
) );
if ( $news_2->have_posts() ) {
while ( $news_2->have_posts() ) {
$news_2->the_post();
$count = $news_2->post_count;
if ($count == '0') {
?>
<li><h3>No Post</h3></li>
<?php
} else {
?>
<li><h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a</h3></li>
<?php } ?>
<?php } } ?> <?php wp_reset_query(); ?>
But instead of the total of posts, I not getting any thing.
Any suggestions to fix this?

It sounds like what you wanted to use was $news_2->found_posts instead of $news_2->post_count.

Remove duplicate post variation in WooCommerce

Need a query to remove duplicate post variation like this situation, in all products:
Just load the product edit page by adding this code into the functions.php file of your active theme, then remove the code. Please change the product ID in the code below.
<?php if (isset( $_GET['post'])) {
$current_list = array();
$args = array(
'posts_per_page' => 500,
'post_type' => 'product_variation',
'orderby' => 'title',
'order' => 'asc',
'offset' => 0,
'ID' => 1631819251, //Parent ID
);
$the_query = new WP_Query( $args );
if ($the_query->have_posts()) {
while ( $the_query->have_posts() ) :
$the_query->the_post(); ?>
<?php the_title(); ?><br>
<?php $this_variation_title = get_the_title();
if (in_array($this_variation_title, $current_list)) {
echo $this_variation_title.' duplicate deleted.<br>';
wp_delete_post(get_the_ID());
} else {
array_push($current_list, $this_variation_title);
echo 'Variation added to array.<br>';
} ?>
<?php endwhile; ?>
<?php } ?>
<?php wp_reset_postdata();
} ?>

List All posts under its own category title WP Query

Hi Hope You All doing well, I implemented a search for posts that are connected to categories child and then the parent of that child everything works perfect in search but I want to bring the search post under its own category and not to repeat that category title again and again for the post title here is my code script and check screenshot here what I mean to say
screenshot before search https://prnt.sc/10kzkvp
screenshot after search https://prnt.sc/10kzmxt As you can see here I want to list posts inside its own category and not repeat the category title for its post, let me know if need more explanation
<?php
$args = array(
'post_type' => 'post',
'extend_where' => "(post_title like '%$s_word%')",
'posts_per_page' => -1,
'orderby'=> 'title',
'order' => 'ASC'
);
// The Query
$the_query = new WP_Query( $args );
// The Loop
if ( $the_query->have_posts() ) {
$icon_flag = false;
$child_c = "";
$parent_c = "";
while ( $the_query->have_posts() ) {
$the_query->the_post();
$split_title = explode(',', get_the_title(), 2);
$id = get_the_ID();
$current_cate = get_the_terms($id,'category');
$parent = $current_cate[0]->parent;
//load object for parent category
$parent_name = get_the_category_by_ID($parent);
if($parent_name != $parent_c && $parent != 0)
{
$parent_c = $parent_name;
?>
<h1 class="grand-p-title p-parent"><?php echo $parent_c; ?></h1>
<?php
}
if($current_cate[0]->name != $child_c )
{
$child_c = $current_cate[0]->name;
?>
<!-- <h1 class="grand-p-title p-child"><?php //echo $current_cate[0]->name; ?></h1> -->
<?php
}
?>
<p class="post-letters"><span class="first-w"><?php echo $split_title[0].", ";?></span><?php echo $split_title[1]; ?></p>
<?php
}
}else
{
?>
<p class="post-letters"><a>No posts founds</a></p>
<?php
}
wp_reset_query();
?>
I think you are doing wrong. you need to loop of categories first and then based on the category you have to get posts. for fetch all categories you can use WP get_terms()
<?php
$terms = get_terms( array (
'taxonomy' => 'category',
'hide_empty' => false
) );
// run a query for each term
foreach( $terms as $term ) {
// Define the query
$args = array(
'post_type' => 'post',
'cat' => $term->term_id,
'extend_where' => "(post_title like '%$s_word%')",
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'ASC'
);
// run the query
$the_query = new WP_Query( $args );
if( $the_query->have_posts() ) {
$icon_flag = false;
$child_c = "";
$parent_c = "";
while ( $the_query->have_posts() ) { $the_query->the_post();
$split_title = explode(',', get_the_title(), 2);
$id = get_the_ID();
$current_cate = get_the_terms($id,'category');
$parent = $current_cate[0]->parent;
//load object for parent category
$parent_name = get_the_category_by_ID($parent);
if($parent_name != $parent_c && $parent != 0) {
$parent_c = $parent_name; ?>
<h1 class="grand-p-title p-parent"><?php echo $parent_c; ?></h1>
<?php }
if($current_cate[0]->name != $child_c ) {
$child_c = $current_cate[0]->name; ?>
<!-- <h1 class="grand-p-title p-child"><?php //echo $current_cate[0]->name; ?></h1> -->
<?php } ?>
<p class="post-letters"><span class="first-w"><?php echo $split_title[0].", ";?></span><?php echo $split_title[1]; ?></p>
<?php }
}else { ?>
<p class="post-letters"><a>No posts founds</a></p>
<?php } wp_reset_query();

Wordpress - List all posts by year with pagination

Right now I'm using the following code to display all posts by year:
index.php
<?php foreach(posts_by_year() as $year => $posts) : ?>
<h2><?php echo $year; ?></h2>
<ul>
<?php foreach($posts as $post) : setup_postdata($post); ?>
<li>
<?php the_title(); ?>
</li>
<?php endforeach; ?>
</ul>
<?php endforeach; ?>
functions.php
function posts_by_year() {
// array to use for results
$years = array();
// get posts from WP
$posts = get_posts(array(
'numberposts' => -1,
'orderby' => 'post_date',
'order' => 'ASC',
'post_type' => 'post',
'post_status' => 'publish'
));
// loop through posts, populating $years arrays
foreach($posts as $post) {
$years[date('Y', strtotime($post->post_date))][] = $post;
}
// reverse sort by year
krsort($years);
return $years;
}
And right now I have set at the reading options in the admin panel that I only want to show 3 posts per page. With this new code, the posts by year, it displays all posts and in the pagination buttons there are 3 pages. When switching to another page, it displays the same content all over again.
How can I include the pagination now that I have posts by year? My pagination code is:
<?php if(function_exists('wpex_pagination')) { wpex_pagination(); } ?>
Which calls the function:
if ( !function_exists( 'wpex_pagination' ) ) {
function wpex_pagination() {
$prev_arrow = is_rtl() ? '→' : '←';
$next_arrow = is_rtl() ? '←' : '→';
global $wp_query;
$total = $wp_query->max_num_pages;
$big = 999999999; // need an unlikely integer
if( $total > 1 ) {
if( !$current_page = get_query_var('paged') )
$current_page = 1;
if( get_option('permalink_structure') ) {
$format = 'page/%#%/';
} else {
$format = '&paged=%#%';
}
echo paginate_links(array(
'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
'format' => $format,
'current' => max( 1, get_query_var('paged') ),
'total' => $total,
'mid_size' => 3,
'type' => 'list',
'prev_text' => $prev_arrow,
'next_text' => $next_arrow,
) );
}
}
}
The idea is that I'm able to set a number of posts to be displayed. Not by year, but by posts. So if I have 30 from 2014 and 20 from 2013 and have the limit set to 5, it'll only show the first 5 from 2014.
Thanks in advance!
EDIT: Also found the following code, which works, but only on the first page. Meaning that in the first page it shows the date once, but in the following pages it shows the date for each post.
<?php
$date = 0;
$newDate = true;
if (have_posts()) : while (have_posts()) :
the_post();
if ($date == 0)
$date = the_date('Y');
else if ($date != the_date('Y')) {
$date = the_date('Y');
$newDate = true;
}
if ($newDate)
echo $date . ' ';
$newDate = false; ?>
<?php get_template_part('content'); ?>
<?php endwhile; endif; ?>

Shortcode rendering as text not as shortcode should

I am building a shopping website and I am trying to put a shortcode in that will show the customer a buy button and the quantity of the product the customer wants to purchase. On my post page the shortcode works fine:
http://warringah-plastics.com.au/blog/dt_catalog/recess-gasket-large/
but on the archive page:
http://warringah-plastics.com.au/store/
the shortcode id displayed as text and not the actual button and quantity e.g. [add_to_cart item="FPROWAR-160713-1" showprice="no" quantity="user:1" ajax="yes" ].
The code that works in the post page is this:
<?php
$my_textbox_value = mtbxr_val("shopping_shortcode");
echo do_shortcode("$my_textbox_value");
?>
but it just displays the shortcode text on that archive page. Anyone have any ideas? Much appreciated,

?>
</div>
</div>
</div>
Try using single quotes in the do_shortcode call, like so:
echo do_shortcode('$my_textbox_value');
More likely though is that the shortcode isn't defined on the archive page so you'd need to look at where it is being instantiated to see if that is the issue. Normally when a shortcode just echoes out the content it means that shortcode doesn't exist. You can test easily enough by using the shortcode_exists() function:
<?php if ( shortcode_exists( 'add_to_cart' ) ) { echo "The shortcode exists";} ?>
If that doesn't work then you know the issue is with the shortcode not being registered on your archives page. If it does work then you know it's something with the format of the content being passed to the shortcode.
Add this to your functions.php
// Allow shortcodes on widgets
add_filter('widget_text','do_shortcode');
// Allow shortcodes on pages (not tested, but should work)
add_filter('the_content','do_shortcode');
Typically your shortcode is getting registered in a plugin or your theme's functions.php file. In a plugin it's often something like:
add_action('init', 'register_my_shortcode');
function register_my_shortcode(){
add_shortcode('my_shortcode', 'do_my_shortcode');
}
And then you'd have a function do_my_short_code() that actually outputs the content. With something like that the shortcode is getting registered via the 'init' hook (http://codex.wordpress.org/Plugin_API/Action_Reference) which is called before WP has started figuring out what template to use, what content to output, etc.
But some plugins will register the shortcode in a way that it is only available on pages / posts where it's going to potentially be used. For example, I can think of one plugin where they register the shortcode and enqueue some javascripts in the same function. That function checks to see if you're on a particular page before it executes so that the js files are not included unnecessarily all over the place. Since the shortcode registration takes place in the same function it means the shortcode only exists on those pages.
Anyhow, if the shortcode is showing as existing on your archives page you know that isn't the problem, so check that first and let me know what you find.

How to push a page's custom field data as a value within a template file?

Long story short. I'm trying to expand the functionality of a portfolio template. It currently can only handle one page. I can duplicate the template, relying on custom fields to pull in specific portfilio items (the theme uses custom post types).
So, here's the bit from my portfolio-template.php:
$args = array(
'post_type' => 'portfolio',
'orderby' => 'menu_order',
'order' => 'ASC',
'meta_value' => 'ao',
'posts_per_page' => -1
);
So, I want to create a new page, select the portfolio template, then define a custom field on that page that will pass on the meta_value to the portfolio-template.php
So it would look like this instead:
$args = array(
'post_type' => 'portfolio',
'orderby' => 'menu_order',
'order' => 'ASC',
'meta_value' => 'PULL_VALUE_FROM_CUSTOM_FIELD',
'posts_per_page' => -1
);
With "PULL_VALUE_FROM_CUSTOM_FIELD" being the bit that I can't figure out. Sorry if my vernacular is code_crude, I'm new at this!
EDIT: Adding in the full code of the template
<?php
$args = array(
'post_type' => 'portfolio',
'orderby' => 'menu_order',
'order' => 'ASC',
'meta_value' => 'ao',
'posts_per_page' => -1
);
$portfolio_query = new WP_Query($args);

Before the Loop, you can access the global variable $post, which in case of single.php and page.php will represent that very post type (post/page/cpt) object that will be displayed by the template file.
If not mistaken, when used in category.php, for example, it will grab the first one.
So, in the case in question:
<?php
global $post;
$the_meta = get_post_meta( 'custom_field_name', $post->ID );
if( !$the_meta )
$the_meta = 'your_backup_solution';
$args = array(
'post_type' => 'portfolio',
'orderby' => 'menu_order',
'order' => 'ASC',
'meta_value' => $the_meta,
'posts_per_page' => -1
);
$portfolio_query = new WP_Query($args);
// et cetera
