我需要帮助来自定义默认的WordPress搜索。我不想在WordPress搜索中包括标题，内容或摘录，但想根据该帖子的元值进行搜索。
在默认的WordPress搜索中，WordPress在"one_answers"条件中添加元查询。如果有一种方法，如果元查询添加或条件也可以。
请帮助
如果您指的是在搜索结果页面上更改 MAIM 查询(例如http://example.com/?s=hello(，请尝试以下一个选项：
选项＃1
这是：
我不想在WordPress中包括标题或内容或摘录 搜索
挂钩到pre_get_posts并为s参数清空。
add_action( 'pre_get_posts', function( $wp_query ){
if ( $wp_query->is_main_query() && $wp_query->is_search() ) {
$wp_query->set( 's', '' );
}
});
选项＃2
这是：
在默认的WordPress搜索中 健康(状况。如果有一种方法，如果元查询添加或条件，它将 也可以。
挂钩到get_meta_sql，然后用AND代替CC_5。
add_filter( 'get_meta_sql', function( $sql, $meta_query, $type, $primary_table ){
global $wpdb;
if (
'post' === $type &&
$wpdb->posts === $primary_table &&
is_main_query() && is_search()
) {
if ( $sql['where'] && ' AND (' === substr( $sql['where'], 0, 6 ) ) {
$sql['where'] = ' OR ' . substr( $sql['where'], 5 );
}
}
return $sql;
}, 10, 4 );
选项＃3
创建一个自定义搜索页面并使用自定义WP_Query实例查询帖子。
$q = new WP_Query([
'meta_key' => 'some_key',
'meta_value' => 'some_value',
// Or use meta_query
]);
选项＃1和＃2都是棘手的，并且可能与网站上的插件或任何自定义代码进行了冲突，或者修改与搜索相关的参数/查询的任何自定义代码。甚至是标准查询。因此，请自己使用代码。
希望有帮助..
i从其中创建一个ajax，从其中我将输入文本发送为" search_text"，并检查文本是元素是否来自meta_key" job_is_featured" job_is_featured"值，该值存储在postmeta中。还要签到自定义邮政类型类别ID。
$catids = '22';
$args = array(
'post_type' => 'job', 'order' => 'DESC','posts_per_page' => '-1','s' => 'search_text' ,'orderby' => 'meta_value',
'tax_query' => array(
array(
'taxonomy' => 'job-category',
'field' => 'term_id',
'terms' => $catids,
),
),
'meta_query' => array(
'relation' => 'AND',
array(
'relation' => 'OR',
array(
'key' => 'job_is_featured',
'value' => 1,
'compare' => '=',
),
array(
'key' => 'job_is_featured',
'value' => 0,
'compare' => '=',
),
),
array(
'key' => 'job_location',
'value' => 'search_text',
'compare' => 'LIKE',
),
),
);
$the_query = new WP_Query( $args );
这是您需要添加functions.php
的代码此代码将与后元和分类法一起使用
if(!function_exists('custom_wp_meta_and_tax_search')){
function custom_wp_meta_and_tax_search($search_args){
/* taxonomy query and meta query arrays */
$tax_query = array();
$meta_query = array();
/* Keyword Based Search */
if( isset ( $_GET['keyword'] ) ) {
$keyword = trim( $_GET['keyword'] );
if ( ! empty( $keyword ) ) {
$search_args['s'] = $keyword;
}
}
/* Custom Meta Key Parameter */
if( isset($_GET['meta_input']) && ($_GET['meta_input'] != 'any')){
$meta_query[] = array(
'key' => 'custom_meta_key',
'value' => $_GET['meta_input'],
'compare' => 'like',
);
}
$min_value = '';
$max_value = '';
if(isset($_GET['min-value']) && $_GET['min-value'] <> 'any'){
$min_value = $_GET['min-value'];
}
if(isset($_GET['max-value']) && $_GET['max-value'] <> 'any'){
$max_value = $_GET['max-value'];
}
/* Logic for Min and Max value Parameters */
/* You need to replace custom_tax with custom taxonomy */
if( isset($min_value) && ($min_value != 'any') && isset($max_value) && ($max_value != 'any') ){
$min_value = doubleval($min_value);
$max_value = doubleval($max_value);
if( $min_value >= 0 && $max_value > $min_value ){
$meta_query[] = array(
'key' => 'custom_tax',
'value' => array( $min_value, $max_value ),
'type' => 'NUMERIC',
'compare' => 'BETWEEN'
);
}
}else if( isset($min_value) && ($min_value != 'any') ){
$min_value = doubleval($min_value);
if( $min_value > 0 ){
$meta_query[] = array(
'key' => 'custom_tax',
'value' => $min_value,
'type' => 'NUMERIC',
'compare' => '>='
);
}
}else if( isset($max_value) && ($max_value != 'any') ){
$max_value = doubleval($max_value);
if( $max_value > 0 ){
$meta_query[] = array(
'key' => 'custom_tax',
'value' => $max_value,
'type' => 'NUMERIC',
'compare' => '<='
);
}
}
// /* if more than one taxonomies exist then specify the relation */
$tax_count = count( $tax_query );
if( $tax_count > 1 ){
$tax_query['relation'] = 'AND';
}
/* if more than one meta query elements exist then specify the relation */
$meta_count = count( $meta_query );
if( $meta_count > 1 ){
$meta_query['relation'] = 'AND';
}
if( $tax_count > 0 ){
$search_args['tax_query'] = $tax_query;
}
/* if meta query has some values then add it to base home page query */
$search_args['meta_query'] = $meta_query;
/* Sort By meta value */
/* You need to replace "custom_meta_key" with the key of custom field you created with post. */
if( (isset($min_value) && ($min_value != 'any')) || ( isset($max_value) && ($max_value != 'any') ) ){
$search_args['orderby'] = 'meta_value_num';
$search_args['meta_key'] = 'custom_meta_key';
$search_args['order'] = 'ASC';
}
return $search_args;
}
}
add_filter('custom_search_parameters','custom_wp_meta_and_tax_search');
现在运行查询并使用元元和分类法
过滤您的帖子$custom_search_args = array(
'post_type' => 'post',
'posts_per_page' => -1,
'paged' => $paged,
);
$custom_search_args = apply_filters('custom_search_parameters',$custom_search_args);
$search_query = new WP_Query( $custom_search_args );
添加此函数.php
add_action( 'pre_get_posts', function( $q )
{
if( $title = $q->get( '_meta_or_title' ) )
{
add_filter( 'get_meta_sql', function( $sql ) use ( $title )
{
global $wpdb;
// Only run once:
static $nr = 0;
if( 0 != $nr++ ) return $sql;
// Modified WHERE
$sql['where'] = sprintf(
" AND ( %s OR %s ) ",
$wpdb->prepare( "{$wpdb->posts}.post_title like '%%%s%%'", $title),
mb_substr( $sql['where'], 5, mb_strlen( $sql['where'] ) )
);
return $sql;
});
}
});
用法
$meta_query = array();
$args = array();
$search_string = "test";
$meta_query[] = array(
'key' => 'staff_name',
'value' => $search_string,
'compare' => 'LIKE'
);
$meta_query[] = array(
'key' => 'staff_email',
'value' => $search_string,
'compare' => 'LIKE'
);
//if there is more than one meta query 'or' them
if(count($meta_query) > 1) {
$meta_query['relation'] = 'OR';
}
// The Query
$args['post_type'] = "staff";
$args['_meta_or_title'] = $search_string; //not using 's' anymore
$args['meta_query'] = $meta_query;
$the_query = new WP_Query($args)
if($ query-＆gt; is_search((({
$meta_query = $query->get( 'meta_query' );
//print_r($meta_query);
$meta_query[] = array('key' => '_product_attributes', /* Product Attribute Meta key Here example (_sku, _stock, _stock_status, height, width ) */
'value' => $city,
'compare' => 'LIKE');
$query->set( 'meta_query', $meta_query );
}
}
}
add_action('woocommerce_product_query'，'add_custom_search2'(;
