WordPress query_post 按标题？

问题描述

是否可以使用 WP_Query 或 query_posts 使用标题创建一个循环的帖子？

即

$args = array('post_title'='LIKE '.$str.'% ');

$res = WP_Query($arg);

// the loop...


// trying this now...
$mypostids = $wpdb->get_col("select ID from $wpdb->posts where post_title like 'Abb%' ");

echo count($mypostids).", ";    // works but can't echo out array of IDs for the next args?

$args = array(
    'post__in'=> $mypostids
);

$res = WP_Query($args);

while( $res->have_posts() ) : $res->the_post(); ...

最佳解决方案

我会这样做：

的 functions.php

<?php
add_filter( 'posts_where', 'title_like_posts_where', 10, 2 );
function title_like_posts_where( $where, &$wp_query ) {
    global $wpdb;
    if ( $post_title_like = $wp_query->get( 'post_title_like' ) ) {
        $where .= ' AND ' . $wpdb->posts . '.post_title LIKE '' . esc_sql( $wpdb->esc_like( $post_title_like ) ) . '%'';
    }
    return $where;
}
?>

然后：

$args = array(
    'post_title_like' => $str
);
$res = WP_Query($arg);

次佳解决方案

得到这个工作与最后的这个职位的帮助。干杯们

$finalArgs =  array (
        'posts_per_page'=>5,
        'order' => 'ASC',
        'post_type' => 'school'
    );

    // Create a new instance
    $searchSchools = new WP_Query( $finalArgs );

    $mypostids = $wpdb->get_col("select ID from $wpdb->posts where post_title LIKE '".$str."%' ");

    $args = array(
        'post__in'=> $mypostids,
        'post_type'=>'school',
        'orderby'=>'title',
        'order'=>'asc'
    );

    $res = new WP_Query($args);

    while( $res->have_posts() ) : $res->the_post();

        global $post;

        $EstablishmentNumber = get_post_meta($post->ID,'EstablishmentNumber', true);

        $schl = array('id'=>$EstablishmentNumber, 'label'=>$post->post_title , 'value'=>$EstablishmentNumber );
        $matchedSchools[] = $schl;


    endwhile;
