更改搜索查询wordpress

我有一个通过自定义帖子类型运行的搜索查询,但是它搜索文本的所有部分,而不是完整的句子。

例如如果您搜索Menta作为公司名称,它还将在文本内容中显示带有Comple menta ry的条目。

我需要在下面找到一种修改此功能的方法,使其仅搜索帖子标题,而不进行其他任何搜索,这将是理想的解决方案。或者,如果那不可能,则仅搜索完整单词而不是部分内容。我希望这是有道理的。

这是代码:

    function aitIncludeMetaInSearch($where) {
        remove_filter('posts_where', 'aitIncludeMetaInSearch');

        global $wpdb;
        // this filter callbeck can be used in ajax requests
        // search string doesn't exist in ajax requests
        // therefore search keyword must be passed as a global query from other scope
        global $__ait_query_data;
        $searchKeyword = $__ait_query_data['search-params']['s'];

        // list of meta keys where we are searching
        $metaKeys = array('subtitle', 'features_search_string');
        $metaKeys = "'" . implode( "', '", esc_sql( $metaKeys ) ) . "'";

        $toFind = "(".$wpdb->posts . ".post_title";

        $likeClause = $wpdb->esc_like( $searchKeyword );
        $likeClause = '%' . $likeClause . '%';

        // search in postmeta values and return array of post ids
        $subQuery = $wpdb->prepare(
            "SELECT group_concat(post_id) as ids FROM {$wpdb->postmeta} AS postmeta
                WHERE postmeta.meta_value LIKE %s
                AND postmeta.meta_key IN ({$metaKeys})",
            $likeClause
        );
        $subQuery = "(FIND_IN_SET(".$wpdb->posts.".ID, (".$subQuery."))) OR ";

        $subqueryLength = strlen($subQuery);

        $positions = aitFindStrPos($toFind, $where);

        $newWhere = $where;
        for ($i = 0; $i < sizeof($positions); $i++) {
            // insert subquery on each position where $toFind occured
            // consider that each next position is moved by the length of previously inserted subquery
            $newWhere = substr_replace($newWhere, $subQuery, $positions[$i] + $i * $subqueryLength, 0);
        }

        // Return revised WHERE clause
        return $newWhere;
    }

任何帮助都会很棒:D

此功能似乎旨在添加元搜索,而不是将现有搜索仅限于帖子标题。如果要这样做,请尝试删除已有的代码,然后在此处使用代码:

Make wordpress search only in post title

全字vs部分匹配不能通过LIKE查询来完成,而可以通过正则表达式来实现

请参阅:Search for "whole word match" in MySQL

function aitIncludeMetaInSearch($where) {
    remove_filter('posts_where', 'aitIncludeMetaInSearch');

    global $wpdb;
    // this filter callbeck can be used in ajax requests
    // search string doesn't exist in ajax requests
    // therefore search keyword must be passed as a global query from other scope
    global $__ait_query_data;
    $searchKeyword = $__ait_query_data['search-params']['s'];

    // list of meta keys where we are searching
    $metaKeys = array('subtitle', 'features_search_string');
    $metaKeys = "'" . implode( "', '", esc_sql( $metaKeys ) ) . "'";

    $toFind = "(".$wpdb->posts . ".post_title";

    $likeClause = $wpdb->esc_like( $searchKeyword );
    $regexClause = '[[:<:]]' . $likeClause . '[[:>:]]';

    // search in postmeta values and return array of post ids
    $subQuery = $wpdb->prepare(
        "SELECT group_concat(post_id) as ids FROM {$wpdb->postmeta} AS postmeta
            WHERE postmeta.meta_value REGEXP %s
            AND postmeta.meta_key IN ({$metaKeys})",
        $regexClause
    );
    $subQuery = "(FIND_IN_SET(".$wpdb->posts.".ID, (".$subQuery."))) OR ";

    $subqueryLength = strlen($subQuery);

    $positions = aitFindStrPos($toFind, $where);

    $newWhere = $where;
    for ($i = 0; $i < sizeof($positions); $i++) {
        // insert subquery on each position where $toFind occured
        // consider that each next position is moved by the length of previously inserted subquery
        $newWhere = substr_replace($newWhere, $subQuery, $positions[$i] + $i * $subqueryLength, 0);
    }

    // Return revised WHERE clause
    return $newWhere;
}
