I wanted to update all my pages' excerpt with custom excerpt. So I created my own plugin with few lines of code. I dunno why it is not working, This is my code
function update_my_metadata_new(){
$pages = get_pages();
foreach ( $pages as $page ) {
// Run a loop and update every meta data
if(in_category('books')){
$the_post = array(
'ID' => $page->ID,//the ID of the Post
'post_excerpt' => 'Read books',);
wp_update_post( $the_post );
}
}
}
This plugin will loop into all pages in the given category and update the excerpts, when activated.
and I have enabled excerpts for pages by adding this code.
add_post_type_support( 'page', 'excerpt' );
to the functions.php file.
It looks like you are using in_category outside of the main loop. You need to pass in the ID of the page for in_category to work:
in_category('books', $page->ID )
function update_my_metadata_new(){
$pages = get_pages();
foreach ( $pages as $page ) {
/* pass the page ID here */
if( in_category( 'books', $page->ID ) ){
$the_post = array(
'ID' => $page->ID,//the ID of the Post
'post_excerpt' => 'Read books',
);
wp_update_post( $the_post );
}
}
}
register_activation_hook( __FILE__, 'update_my_metadata_new');

I added the following code to my functions.php file in WordPress 6.1.1 to display excerpts.
function new_excerpt_length($length) {
return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');
function new_excerpt_more($more) {
return '...';
}
add_filter('excerpt_more', 'new_excerpt_more');
...but I also have a use case to show the full excerpt without a read more link.
On page template 1 I add the below code to display the excerpt:
<?php echo the_excerpt(); ?>
...and it displays the excerpt as per the functions.php file but how do I create a 2nd excerpt without the read more link and apply it to page template 2?
Is there a parameter I can use within the_excerpt(parameter); or can I use something like wp_trim_excerpt https://developer.wordpress.org/reference/functions/wp_trim_excerpt/ maybe?
I came across the below code that is supposed to do what I want
function wpex_get_excerpt( $args = array() ) {
// Default arguments.
$defaults = array(
'post' => '',
'length' => 40,
'readmore' => false,
'readmore_text' => esc_html__( 'read more', 'text-domain' ),
'readmore_after' => '',
'custom_excerpts' => true,
'disable_more' => false,
);
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_defaults', $defaults );
// Parse arguments, takes the function arguments and combines them with the defaults.
$args = wp_parse_args( $args, $defaults );
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_args', $args );
// Extract arguments to make it easier to use below.
extract( $args );
// Get the current post.
$post = get_post( $post );
// Get the current post id.
$post_id = $post->ID;
// Check for custom excerpts.
if ( $custom_excerpts && has_excerpt( $post_id ) ) {
$output = $post->post_excerpt;
}
// No custom excerpt...so lets generate one.
else {
// Create the readmore link.
$readmore_link = '' . $readmore_text . $readmore_after . '';
// Check for more tag and return content if it exists.
if ( ! $disable_more && strpos( $post->post_content, '<!--more-->' ) ) {
$output = apply_filters( 'the_content', get_the_content( $readmore_text . $readmore_after ) );
}
// No more tag defined so generate excerpt using wp_trim_words.
else {
// Generate an excerpt from the post content.
$output = wp_trim_words( strip_shortcodes( $post->post_content ), $length );
// Add the readmore text to the excerpt if enabled.
if ( $readmore ) {
$output .= apply_filters( 'wpex_readmore_link', $readmore_link );
}
}
}
// Apply filters and return the excerpt.
return apply_filters( 'wpex_excerpt', $output );
}
Output using:
<?php echo wpex_get_excerpt ( $defaults = array(
'length' => 40,
'readmore' => true,
'readmore_text' => esc_html__( 'read more', 'wpex-boutique' ),
'custom_excerpts' => true,
) ); ?>
...but doesn't seem to workas intended. Outputs the excerpt with no link but the args don't see to work when changed. Would be perfect for my use otherwise. Maybe someone sees how to fix this code?
Thanks
I am using the hook "pre_get_posts" to query only posts that have featured image in the front page:
add_action( 'pre_get_posts', 'my_pre_get_posts' );
function my_pre_get_posts( $q ){
if ( $q->is_home() // only target homepage
&& $q->is_main_query() // only target the main query
&& !is_admin() // target front end only
) {
$q->set( 'meta_key', array( '_thumbnail_id' ) );
}
}
It looks like this portion is being ignored.
$q->set( 'meta_key', array( '_thumbnail_id' ) );
Your help is appreciated.
You need to check whether '_thumbnail_id' meta_key exists or not. So let's modify your code like this.
add_action( 'pre_get_posts', 'my_pre_get_posts' );
function my_pre_get_posts( $q ){
if ( $q->is_home() // only target homepage
&& $q->is_main_query() // only target the main query
&& !is_admin() // target front end only
) {
$meta_query = array(
array(
'key'=>'_thumbnail_id',
'compare'=>'EXISTS',
),
);
$query->set('meta_query',$meta_query);
}
}
I’ve created a frontend form using the advanced custom fields (ACF) plugin. Within this form I’ve added some location fields such as postcode and city.
Below is the function used to update the post
global $post_id;
add_filter('acf/pre_save_post' , 'tsm_do_pre_save_post' );
function tsm_do_pre_save_post( $post_id ) {
// Bail if not logged in or not able to post
if ( ! ( is_user_logged_in() ) ) {
return;
}
// check if this is to be a new post
if( $post_id != 'new_job' ) {
return $post_id;
}
$profile_id = um_profile_id();
$userID = 'user_'.$profile_id;
$user_id = get_current_user_id();
// Create a new post
$post = array(
'ID'=> $post_id,
'post_type' => 'members',
'post_status' => 'publish',
'post_title' => $userID,
'post_author' => $user_id,
'category' => $_POST['acf']['field_594d0ffc2a66d'],
);
// insert the post
$post_id = wp_insert_post( $post );
// Save the fields to the post
do_action( 'acf/save_post' , $post_id );
return $post_id;
exit;
}
Once this form has been submitted, the custom post type is updated with no issues.
How can I add the submitted location data (postcode, city etc) into the GEO MY WP information for the post?
I’ve tried to follow the information in the docs secetion (http://docs.geomywp.com/gmw_pt_update_location/) but not having much luck.
GEO my WP function fron docs below:
function gmw_update_post_type_post_location( $post_id ) {
// Return if it's a post revision
if ( false !== wp_is_post_revision( $post_id ) )
return;
// check autosave //
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
return;
}
//check if user can edit post
if ( !current_user_can( 'edit_post', $post_id ) )
return;
//get the address from the custom field "address"
$address = get_post_meta( $post_id, 'address', true );
//varify that address exists. Otherwise abort the function.
if ( empty( $address ) )
return;
//include the update location file file
include_once( GMW_PT_PATH .'/includes/gmw-pt-update-location.php' );
//make sure the file included and the function exists
if ( !function_exists( 'gmw_pt_update_location' ) )
return;
//Create the array that will pass to the function
$args = array(
'post_id' => $post_id, //Post Id of the post
'address' => $address // the address we pull from the custom field above
);
//run the udpate location function
gmw_pt_update_location( $args );
}
//execute the function whenever post type is being updated
add_action( 'save_post_post', 'gmw_update_post_type_post_location' );
I believe I need to somehow combine the two functions so when the ACF form is updated, it also needs to update the GEO my wp meta data also.
I've tried combining the two functions but not having much luck.
If someone can point me in the right direction it will be very much appreciated
Thanks
Updated code.....
I've tried to add the gmw_update_post_type_post_location() function within the ACF function (code below) but still not having much luck...
global $post_id;
add_filter('acf/pre_save_post' , 'tsm_do_pre_save_post' );
function tsm_do_pre_save_post( $post_id ) {
// Bail if not logged in or not able to post
if ( ! ( is_user_logged_in() ) ) {
return;
}
// check if this is to be a new post
if( $post_id != 'new_job' ) {
return $post_id;
}
$profile_id = um_profile_id();
$userID = 'user_'.$profile_id;
$user_id = get_current_user_id();
$profilePostcode = get_post_meta( $post_id, 'location_postcode', true );
// Create a new post
$post = array(
'ID'=> $post_id,
'post_type' => 'members', // Your post type ( post, page, custom post type )
'post_status' => 'publish', // You can use -> publish, draft, private, etc.
'post_title' => $userID, // Post Title ACF field key
'post_author' => $user_id,
'category' => $_POST['acf']['field_594d0ffc2a66d'], // Post Content ACF field key
);
// insert the post
$post_id = wp_insert_post( $post );
// Save the fields to the post
do_action( 'acf/save_post' , $post_id );
gmw_update_post_type_members_location($post_id);
return $post_id;
exit;
}
function gmw_update_post_type_members_location( $post_id ) {
$profilePostcode = get_post_meta( $post_id, 'profile_location_postcode', true );
if ( empty( $profilePostcode ) )
return;
$address = array(
//'street' => $_POST['location_address'],
//'city' => $_POST['location_town'],
//'state' => $_POST['location_state'],
'zipcode' => $profilePostcode,
//'country' => $_POST['location_country']
);
include_once( GMW_PT_PATH .'/includes/gmw-pt-update-location.php' );
if ( !function_exists( 'gmw_pt_update_location' ) )
return;
$profile_id = um_profile_id();
$userID = 'user_'.$profile_id;
$user_id = get_current_user_id();
$args = array(
'post_id' => $post_id, //Post Id of the post

);
//run the udpate location function
gmw_pt_update_location( $args );

I hadn't realised that WordPress had added a native function for it to the Codex, but for some odd reason the page is blank. Does that mean the functionality is still coming or the page was added by mistake?
http://codex.wordpress.org/Function_Reference/get_permalink_by_slug
It's blank because it doesn't exist. If you change that function name to any random name you like you'll still see a blank page (unless of course the name you change it to is a real function).
function get_permalink_by_slug( $slug, $post_type = '' ) {
// Initialize the permalink value
$permalink = null;
// Build the arguments for WP_Query
$args = array(
'name' => $slug,
'max_num_posts' => 1
);
// If the optional argument is set, add it to the arguments array
if( '' != $post_type ) {
$args = array_merge( $args, array( 'post_type' => $post_type ) );
} // end if
// Run the query (and reset it)
$query = new WP_Query( $args );
if( $query->have_posts() ) {
$query->the_post();
$permalink = get_permalink( get_the_ID() );
} // end if
wp_reset_postdata();
return $permalink;
}
I am using woocommerce on my wordpress site.
I am selling paintings. The products are paintings.
I have a list of artists as posts. Each artist is one post.
I would like to connect the posts and products so I can show the artist's name on the painting page and the user can click on the name and it takes them to the artist post.
How do I do this?
This is an example of how to add a custom field in WooCommerce product general tab. Since artists are posts ( category is not specified ), it will collect links for all posts and place them in a dropdown. The value of this field will be visible on the single product page below the price ( you can open the content-single-product.php file in WooCommerce theme, to see the actions for single product template, and functions attached, and change the priority of woocommerce_product_artist function if you want to change the place where the link will appear ).
<?php
add_action( 'admin_init', 'woocommerce_custom_admin_init' );
function woocommerce_custom_admin_init() {
// display fields
add_action( 'woocommerce_product_options_general_product_data', 'woocommerce_add_custom_general_fields' );
// save fields
add_action( 'woocommerce_process_product_meta', 'woocommerce_save_custom_general_fields' );
}
function woocommerce_add_custom_general_fields() {
// creating post array for the options ( id => title)
$posts = array( '' => __( 'Select Artist' ) );
array_walk( get_posts( array( 'numberposts' => -1 ) ), function( $item ) use ( &$posts ) {
$posts[ $item->ID ] = $item->post_title;
} );
// creating dropdown ( woocommerce will sanitize all values )
echo '<div class="options_group">';
woocommerce_wp_select(
array(
'id' => '_artist',
'label' => __( 'Artist' ),
'options' => $posts
)
);
echo '</div>';
}
function woocommerce_save_custom_general_fields( $post_id ) {
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
// validate id of artist page and save
if ( isset( $_POST['_artist'] ) ) {
$value = filter_input( INPUT_POST, '_artist', FILTER_VALIDATE_INT, array( 'options' => array( 'min_range' => 0 ) ) );
update_post_meta( $post_id, '_artist', $value );
}
}
add_action( 'init', 'woocommerce_custom_init' );
function woocommerce_custom_init() {
// hook the woocommerce_product_artist function on to woocommerce_single_product_summary action ( priority 15 )
add_action( 'woocommerce_single_product_summary', 'woocommerce_product_artist', 15 );
}
function woocommerce_product_artist() {
global $post;
// get the artist page id and show in template ( if exists )
$artist_id = get_post_meta( $post->ID, '_artist', true );
if ( $artist_id ) :
?>
<div class="product-artist"><?php echo get_the_title( $artist_id ); ?></div>
<?php endif;
}
?>
