i have a woocommerce e-shop website. My search is searching only in product title and sku fields. I want to search also in some custom fields (like "_barcode" and "_mpn").
I have this script but when i use it in fuctions.php i can't search by product title.
function search_filter( $query ) {
$key_fields = array ( '_barcode', '_mpn', '_sku' );
$value_field = $query->query_vars['s'];
$query->query_vars['s'] = '';
if ( $value_field != '' ) {
$filter_query = array( 'relation' => 'OR' );
foreach ( $key_fields as $one_field ) {
array_push ( $filter_query , array (
'key' => $one_field,
'value' => $value_field,
'compare' => 'LIKE'
) );
}
$query->set( 'meta_query' , $filter_query );
}
}
add_filter( 'pre_get_posts' , 'search_filter');
Why i can't search the product title when i use this script?
Any idea?
Thank you.
I want to display my woocommerce products on two different sections on the site i.e. the shop page and on an archive page i created using Custom Post UI plugin, called artists.
Using the Advanced Custom Fields plugin, i created a field that will attach each product created to an individual artist. The plan now is, on each artist page, pull products for the artist.
This is what i have so far. I hook into woocommerce_product_query, check if i'm on the single artist page and implement my meta query:
function artist_products( $query )
{
if( is_singular('artists') )
{
$meta_query = ( is_array( $query->get('meta_query') ) ) ? $query->get('meta_query') : [];
$meta_query[] = array(
'key' => '_fld_select_artist',
'value' => get_the_ID(),
);
$query->set( 'meta_query', $meta_query );
}
}
add_action( 'woocommerce_product_query', 'artist_products' );
This is not working. When i visit my single artist page, i get a 500 server error. What I'm i missing?
woocommerce_product_query was breaking my site for some reason so i switched to pre_get_posts:
function artist_products( $query )
{
if ( $query->get('post_type') == 'nav_menu_item' )
{
return $query;
}
if( ! is_admin() && is_singular('artists') )
{
$meta_query = ( is_array( $query->get('meta_query') ) ) ? $query->get('meta_query') : [];
$meta_query[] = array(
'key' => '_fld_select_artist',
'value' => get_the_ID(),
'compare' => '=',
);
$query->set( 'meta_query', $meta_query );
}
}
add_action( 'pre_get_posts', 'artist_products' );
I have a gravity form form on my WP site and I recently changed a free text field into a drop down field.
The website is a store which hold several categories of goods and I want my drop-down to show the user all the possible categories he can choose from.
Please assist in how to "pull" the categories into the drop-down list.
Thanks in advance.
You can do using some filters of gravity form, code is following
// Here 1 is form id
add_filter( 'gform_pre_render_1', 'populate_category' );
add_filter( 'gform_pre_validation_1', 'populate_category' );
add_filter( 'gform_pre_submission_filter_1', 'populate_category' );
add_filter( 'gform_admin_pre_render_1', 'populate_category' );
function populate_category( $form ) {
foreach ( $form['fields'] as &$field ) {
if ( $field->type != 'select' || strpos( $field->cssClass, 'populate-category' ) === false ) {
continue;
}
// Get category list
$categories = get_categories( array(
'orderby' => 'name',
'order' => 'ASC'
) );
$choices = array();
foreach( $categories as $category ) {
$choices[] = array( 'text' => $category->name, 'value' => $category->name );
}
$field->placeholder = 'Select a Category';
$field->choices = $choices;
}
return $form;
}
This is working perfectly its tested code.
I would like to query my posts by filtering for a custom meta added with Advanced Custom Fields. It's a boolean meta, so every post will have something like:
GET http://localhost/wp-json/wp/v2/posts
{
...
"acf" : {
"highlight" : true
}
...
}
I'm not able to filter by this meta value, even if I exposed meta_key and meta_value to the REST API in function.php:
function my_add_meta_vars ($current_vars) {
$current_vars = array_merge ($current_vars, array ('meta_key', 'meta_value'));
return $current_vars;
}
add_filter ('rest_query_vars', 'my_add_meta_vars');
But if I try:
GET
http://localhost/wp-json/wp/v2/posts?filter[meta_key]=highlight&filter[meta_value]=true
I see all the posts as if the filter is ignored.
I was able to get this solved with this customization:
add_filter( 'rest_query_vars', function ( $valid_vars ) {
return array_merge( $valid_vars, array( 'highlight', 'meta_query' ) );
} );
add_filter( 'rest_post_query', function( $args, $request ) {
$highlight = $request->get_param( 'highlight' );
if ( ! empty( $highlight ) ) {
$args['meta_query'] = array(
array(
'key' => 'highlight',
'value' => $highlight,
'compare' => '=',
)
);
}
return $args;
}, 10, 2 );
And do a query in this way (highlight is acf boolean)
GET /wp-json/wp/v2/posts?highlight=1
I use wp_list_categories() to get the list of all the categories and generate the navigation bar. Is there a way to order these categories in a particular order other than alphabetical ordering.
eg: Connect, News & Views, Q&A, Hello Startup, Startup 101...
Most themes don't use the description of the category for anything. Easy workaround I did was to use numbers in description. The top post here currently has some jQuery hack from here, it's unneeded.
You can add custom order fields I suppose as well.
Just
$categories = get_categories( array(
'orderby' => 'description',
'order' => 'ASC'
) );
Technical approach
The problem in wordpress core is that the table wp_terms has no term_order column. That means, standard wordpress does not support the custom term order. If you look at this WP database structure you can find the table wp_term_relationships. This table is responsible for the relationships between posts and the taxonomy (your categories) AND this table has a term_order column.
Now, with a simple SQL statement ALTER TABLE wp_terms ADD term_order INT(11) NOT NULL DEFAULT 0 (not forget the $wpdb->wp_terms variable) you can add a column to the table, which is responsible for your custom category order. Then you can put your custom category order in this two columns of wp_term_relationships and wp_terms. When all is finished, you can hook into the filter of get_terms_args and change the orderby to term_order.
Here a list of all relevant links for the technical approach:
https://codex.wordpress.org/Database_Description for the wp database structure
https://codex.wordpress.org/Class_Reference/wpdb for the $wpdb->wp_terms
https://developer.wordpress.org/reference/hooks/get_terms_args/ for the WP filter
A plugin can do the job for you
Check my plugin to solve this: WordPress Real Categories Management. WP RCM creates an extra field term_order on the wp terms table. It also brings a lot of other useful features as you can see in the screenshot below. It allows you to organize your wordpress categories in a nice way. It is easy to use, just drag&drop your categories and move it to a specific order. The plugin works in all Custom post types.
From the product description i can quote. If you want to try the plugin, there is also a demo on the plugin page.
There are a lot of free plugins
This can be solved with a lot of free plugins available within the wordpress.org plugin repository. Simply search for "category order" in your Wordpress Dashboard > Plugins > Install.
This is inbuilt in wordpress_wp_list_categories
wp_list_categories('orderby=name');
I think that would help you out
I did it generating several term lists. I call it later by my own order. I'm a PHP beginner.
First, I store, in a different variable, the ID for each category term:
$terms = get_terms('my_taxonomy', 'hide_empty=0');
foreach ( $terms as $term ) {
${$term->slug} = get_term_by('slug', $term->slug, 'product_cat');
${$term->slug.'_array'} = (array)${$term->slug};
${$term->slug.'_array_id'} =${$term->slug.'_array'}['term_id'];
};
Then, I create several args for each wp_list_categories() excluding, with this variable the terms I want to:
$args = array(
'taxonomy' => 'my_taxonomy',
'orderby' => 'name',
'show_count' => true,
'pad_counts' => false,
'hierarchical' => true,
'title_li' => '',
'hide_empty' => 0,
'show_option_all' => 'Show all',
'exclude' => array( $term1_array_id, $term2_array_id )
);
$args_1 = array(
'taxonomy' => 'my_taxonomy',
'orderby' => 'name',
'show_count' => true,
'pad_counts' => false,
'hierarchical' => true,
'title_li' => '',
'hide_empty' => 0,
'exclude' => array( $term3_array_id, $term4_array_id, $term1_array_id )
);
$args_2 = array(
'taxonomy' => 'my_taxonomy',
'orderby' => 'name',
'show_count' => true,
'pad_counts' => false,
'hierarchical' => true,
'title_li' => '',
'hide_empty' => 0,
'exclude' => array( $term1_array_id, $term4_array_id, $term5_array_id )
);
Finally, I can call separately each term list:
<ul>
<?php wp_list_categories( $args ); ?>
<?php wp_list_categories( $args_1 ); ?>
<?php wp_list_categories( $args_2 ); ?>
</ul>
Use Category Order and Taxonomy Terms Order free plugin
I didn't find anything so I constructed my own method. I abstracted it away in an abstract class for my plugin, hence the extra code, but you can pull the methods.
The main method to look at is format_hierarchy()
// The parent class
abstract class Taxonomy {
protected bool $_terms_loaded;
protected array $terms;
protected array $formatted_terms;
public function __get( $property ) {
if ( $property === 'formatted_terms' ) {
if ( !isset( $this->formatted_terms ) ) $this->format_hierarchy();
return $this->formatted_terms;
}
if ( substr( $property, 0, 1 ) === '_' ) die( 'Cannot get private properties' );
if ( property_exists( $this, $property ) )
return $this->$property;
}
/**

*
* #return array an array of `[term_taxonomy_id:number] => term_block` like:

* 'term' => WP_Term,
* 'children' => array( $term_blocks… )
* ),
* …$term_blocks…
* )
*/
public function format_hierarchy():array {
if ( !$this->_load_terms() ) return [];
// Holds a reference to every category, parents and children
$term_blocks = [];
// Holds a reference to every top most level category
$parents = [];
foreach ( $this->terms as $term ) {
// Add itself to the list of all categories
$term_block = [
'children' => [],
'term' => $term
];
// Add itself to the array of all categories
if ( !isset( $term_blocks[ $term->term_taxonomy_id ] ) )
$term_blocks[ $term->term_taxonomy_id ] =& $term_block;
// If it's a child category…
if ( $term->parent !== 0 ) {
// If the parent hasn't been created yet, create it
if ( !isset( $term_blocks[ $term->parent ] ) )
$term_blocks[ $term->parent ] = [
'children' => [],
'term' => null
];
$term_blocks[ $term->parent ][ 'children' ][] =& $term_block;
} else
// Otherwise it's a parent
$parents[ $term->term_taxonomy_id ] =& $term_blocks[ $term->term_taxonomy_id ];
// set the term block's WP_Term property
$term_blocks[ $term->term_taxonomy_id ][ 'term' ] =& $term;
// This is needed so that the loop doesn't readd the same reference over and over again
unset( $term ); unset( $term_block );
}
return $this->formatted_terms = $parents;
}
/**

*/
public function find_term_by(
$term_val,
string $prop,
bool $with_parent = false,
$term_blocks = null
):?array {
if ( is_null( $term_blocks ) ) $term_blocks = $this->formatted_terms;
foreach ( $term_blocks as $term_block ) {
if ( $term_block[ 'term' ]->{$prop} === $term_val ) return $term_block;
if ( count( $term_block[ 'children' ] ) &&
( $found = $this->find_term_by( $term_val, $prop, false, $term_block[ 'children' ] ) )
) return $with_parent ? [ $found, $term_block ] : $found;
}
return null;
}
/**
* Loads the taxonomy terms once from the DB
*/
protected function _load_terms():bool {
if ( isset( $this->_terms_loaded ) ) return $this->_terms_loaded;
$this->terms = get_terms(
array(static::$taxonomy),
array(
'hide_empty' => false,
)
);
if ( !$this->terms ) {
ClassErrorHandler::handle_exception(
new \WP_Error( 500, 'Failed to load category terms: \'' . static::$taxonomy . '\'' )
);
}
return $this->_terms_loaded = !!$this->terms;
}
}
// The Implementation
class TaxonomyProductService extends Taxonomy {
public static string $taxonomy;
public static string $slug;
/**
* To be called upon taxonomy registration long before any instance is required
*/
public static function define_taxonomy( string $slug, string $taxonomy ) {
static::$slug = $slug;
static::$taxonomy = $taxonomy;
}
}
Right after registering the custom taxonomy I call
TaxonomyProductService::define_taxonomy( 'url-slug', 'product-service' );
And finally how it's used
$tax = new TaxonomyProductService();
$terms = $tax->formatted_terms;
// search for a term whose slug === `my-term`, and return the parent category
list( $current_term, $parent_term ) = $tax->find_term_by( 'my-term', 'slug', true );
For the benefit of future visitors, here’s the easy solution to this problem:
There are now a number of plugins that allow you to order categories or other custom taxonomies in WordPress. You can see some of them in the WordPress plugin directory’s “category order” tag page. I can personally confirm that Custom Taxonomy Order NE plugin does the job.
