I want to list all pages as well as selected pages in A-Z listing in WordPress. I know there are a number of plugins available, but I want this without a plugin.
Update
sorry if question is not clear, i want A-Z listing like attached image
i have solved this issue,
just need to put if condition, here is the code
$arr[0] = array(2=>2983);
$arr[1] = array(2=>2981);
$arr[2] = array('A'=>20);
$arr[3] = array('A'=>25);
print "<pre>";
print_r($arr);
$newArry = array();
foreach ($arr as $a) {
foreach ($a as $key => $value) {
if (array_key_exists($key, $newArry)) {
//$newArry[$key] = array($value);
array_push($newArry[$key], $value);
} else {
$newArry[$key] = array($value);
}
echo "<br/> Key ".$key ." => Value ".$value;
//print_r($b);
}
}
print_r($newArry);
You can use a WP_Query, as page is simply a post type.
$args = array(
'post_type' => 'page',
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'ASC',
);
$query = new WP_Query( $args );
$pages = $query->posts;
See WP_Query documentation.

How can I get a serial number of current post in category?
For ex. I have a category Cars with 4 posts in it. When I open some post I want to see navigation like this: Post 3 of 4 [<<] [>>]
Most straightforward way is querying the posts in the category, like this:
// WP_Query arguments
$args = array (
'category_name' => 'cars',
'posts_per_page' => '-1',
'order' => 'DESC',
'orderby' => 'date',
);
// The Query
$query = new WP_Query( $args );
Then you can get the number of posts with
// $query->found_posts gives the number of posts the query has found
// with the parameters you set
echo $query->found_posts;
And you can count up the post you display:
$count = 0;
foreach ( $query->posts as $count_post ) {
$count++;
// assuming you are inside The Loop
if ( get_the_ID() == $count_post->ID ) {
break;
}
}
// now you can get the "serial number" of the post
echo $count;
This might not be the most "WP way" of doing it, but it should work. :)
How can i get the no of posts inside a term of a custom taxonomy ? (including the posts that are attached to a child term).
For example i have:
term (2 posts)
-child term (2 posts)
--child child term (1 post)
Right now i'm, doing it like this:
$categories = get_terms($taxonomy,$args);
foreach ($categories as $categ) {
print $categ->name.' / '.$categ->count;
}
But for "term" i get only 2 posts when i really need to show 5( 2 from "term" and 3 from it's children).
Thanks
There is an easier way to do this: do a standard WP_Query with taxonomy parameters:
$args = array(
'post_type' => 'post',
'tax_query' => array(
array(
'taxonomy' => 'your_custom_taxonomy',
'field' => 'slug',
'terms' => 'your-parent-term-name',
),
),
);
$query = new WP_Query( $args );
// Get the count
$count = $query->post_count;
If you don't know the name(s) of terms within a taxonomy, you can do a query and pass their IDs as an array to WP_Query. See this post on WPSE for more info.
This is something I run into few times, and I changed the code from PatchRanger on bountify to make it work with taxonomies (so please note this solution is based on his work):
function wp_get_term_postcount($term) {
$count = (int) $term->count;
$tax_terms = get_terms($term->taxonomy, array('child_of' => $term->term_id));
foreach ($tax_terms as $tax_term) {
$count += wp_get_term_postcount_recursive($tax_term->term_id);
}
return $count;
}
function wp_get_term_postcount_recursive($term_id, $excludes = array()) {
$count = 0;
foreach ($tax_terms as $tax_term) {
$tax_term_terms = get_terms($tax_term->name, array(
'child_of' => $tax_term->term_id,
'exclude' => $excludes,
));
$count += $tax_term->count;
$excludes[] = $tax_term->term_id;
$count += wp_get_term_postcount_recursive($tax_term->term_id, $excludes);
}
return $count;
}
The recursive function is there to prevent double counting of childs. You can add those two functions inside functions.php.
Then update your code to use it:
$categories = get_terms($taxonomy, $args);
foreach($categories as $categ) {
print $categ->name.' / 'wp_get_term_postcount($categ);
}
I am currently using the Multi Post Thumbnails plugin for Wordpress, but I only want the extra thumbnails provided by the plugin to show on one specific page. The plugin does not appear to natively support this functionality but it seems like something that would be pretty easy to add, I'm just not sure of the right way to go about it as I'm fairly new to Wordpress development.
The code for Multi Post Thumbnails is the following, which simply goes in functions.php:
if (class_exists('MultiPostThumbnails')) {
new MultiPostThumbnails(
array(
'label' => 'Secondary Image',
'id' => 'secondary-image',
'post_type' => 'page'
)
);
new MultiPostThumbnails(
array(
'label' => 'Tertiary Image',
'id' => 'tertiary-image',
'post_type' => 'page'
)
);
}
It seems to me it would just be a simple case of wrapping this in a check so that it only runs for a specific page ID, but I'm not quite sure how to go about doing that.
This is probably somewhat of a hack. To my knowledge post/page id's are not accessible from inside functions.php.
// get the id of the post/page based on the request uri.
$url = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
$post_id = url_to_postid($url);
// the id of the specific page/post.
$specific_post_id = 3;
// check if the requested post id is identical to the specific post id.
if ($post_id == $specific_post_id) {
if (class_exists('MultiPostThumbnails')) {
new MultiPostThumbnails(
array(
'label' => 'Secondary Image',
'id' => 'secondary-image',
'post_type' => 'page'
)
);
new MultiPostThumbnails(
array(
'label' => 'Tertiary Image',
'id' => 'tertiary-image',
'post_type' => 'page'
)
);
}
}
This is also probably a hack but it worked for me. I got stung by the AJAX 'post_id' back to the admin page once the image has been selected. My usage was for a slug but the function could easily be modified for a post ID.
function is_admin_edit_page( $slug ){
if( ( isset($_GET) && isset($_GET['post']) ) || ( isset($_POST) && isset($_POST['post_id']) ) )
{
$post_id = 0;
if(isset($_GET) && isset($_GET['post']))
{
$post_id = $_GET['post'];
}
else if(isset($_POST) && isset($_POST['post_id']))
{
$post_id = $_POST['post_id'];
}
if($post_id != 0)
{
$c_post = get_post($post_id);
if( $c_post->post_name == $slug )
{
return true;
}
}
}
return false;
}
if( is_admin_edit_page('work') ) {
new MultiPostThumbnails(
array(
'label' => 'Hero 1 (2048px x 756px JPEG)',
'id' => 'am-hero-1',
'post_type' => 'page'
)
);
}
I've been trying to get this seemingly easy peace of code to work.
I'm loading rss from a wordpress site and it all works fine except for the thumbnails. Since in the XML they are set as an attribute instead of a nodeValue i can't seem to get import them. (i've really tried a lot)
$rss = new DOMDocument();
$rss->load('http://goalprogramme.wordpress.com/feed/');
$feed = array();
foreach ($rss->getElementsByTagName('item') as $node) {
// in XML it looks like <media:thumbnail url="http://goalprogramme.files.wordpress.com/2014/01/dsc_0227.jpg?w=150"/>
//echo $node->getElementsByTagName('media:thumbnail')->item(0)->getAttribute('url');
//push items
$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,
'thumbnail' => $node->getElementsByTagName('media:thumbnail')->item(0)->getAttribute('url') // this line doesn't work !!!
);
array_push($feed, $item);
}
Any help would be greatly appreciated.
Thanks so much in advance!
Hours later i've created another piece of code that does work. If anyone needs it it, here it is:
$feed_array = array();
$feed = simplexml_load_file('http://goalprogramme.wordpress.com/feed/');
foreach ($feed->channel->item as $item) {
$title = (string) $item->title;
$description = (string) $item->description;
$link = (string) $item->link;
$date = (string) $item->date;
if ($media = $item->children('media', TRUE)) {
if ($media->thumbnail) {
$attributes = $media->thumbnail->attributes();
$thumbnail = (string)$attributes['url'];
}
}
$item = array (
'title' => $title ,
'desc' => $description,
'link' => $link,
'date' => $date,
'thumbnail' => $thumbnail
);
array_push($feed_array, $item);
}
I show my last post in a page with this code:
$query1 = new WP_Query();
$query1->the_post();
and it further with:
$id = $query->ID;
to retrive last post ID
so I wrote a new wp_query and I want to exclue that ID from the results:
I wrote this but it don't work:
$query2-> new WP_Query('p=-$id');
what's the problem?
You haven't excluded anything. Read the Codex. p= includes posts. It does not exclude them. What you need is post__not_in
$query2-> new WP_Query(array('post__not_in' = array($id)));
My code is works fine:
$ID =array('1,2,3,4,5');
$news = new WP_Query(array('
'post_type' => 'post',
'showposts' =>3,
'order' => 'DESC',
'post__not_in' => $ID
));
if ( $news->have_posts() ) :
echo '<div>';
while ( $news->have_posts() ) : $news->the_post(); ?>`
//Your code here
