Wordpress WP_Query where clause with OR? - Wordpress WP_Query where clause with OR?

你好朋友们，这是我WP_Query的参数。

$args = array('post_type' => 'job_listing');
$args['meta_query']=array(
   'relation' => 'OR',
    array(
        'key' => 'app_trailer-type',
        'value' => $job_tailor,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'app_pay-type',
        'value' => $app_pay_type,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'geo_address',
        'value' => $geo_address,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'geo_country',
        'value' => $geo_country,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'geo_short_address',
        'value' => $geo_short_address,
        'compare' => 'LIKE'
    ),
);

这是返回查询类似。

SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID FROM wp_posts  INNER JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id)
INNER JOIN wp_postmeta AS mt1 ON (wp_posts.ID = mt1.post_id)
INNER JOIN wp_postmeta AS mt2 ON (wp_posts.ID = mt2.post_id)
INNER JOIN wp_postmeta AS mt3 ON (wp_posts.ID = mt3.post_id)
INNER JOIN wp_postmeta AS mt4 ON (wp_posts.ID = mt4.post_id) WHERE 1=1  AND wp_posts.post_type = 'job_listing' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'expired' OR wp_posts.post_status = 'tr_pending' OR wp_posts.post_status = 'tr_failed' OR wp_posts.post_status = 'tr_completed' OR wp_posts.post_status = 'tr_activated' OR wp_posts.post_status = 'private') AND ( (wp_postmeta.meta_key = 'app_trailer-type' AND CAST(wp_postmeta.meta_value AS CHAR) LIKE '%Flatbed%')
AND  (mt1.meta_key = 'app_pay-type' AND CAST(mt1.meta_value AS CHAR) LIKE '%Per Week%')
AND  (mt2.meta_key = 'geo_address' AND CAST(mt2.meta_value AS CHAR) LIKE '%Davenport%')
AND  (mt3.meta_key = 'geo_country' AND CAST(mt3.meta_value AS CHAR) LIKE '%United States%')
AND  (mt4.meta_key = 'geo_short_address' AND CAST(mt4.meta_value AS CHAR) LIKE '%Davenport%') ) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 10

我需要查询该查询。

SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID FROM wp_posts  INNER JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id)
INNER JOIN wp_postmeta AS mt1 ON (wp_posts.ID = mt1.post_id)
INNER JOIN wp_postmeta AS mt2 ON (wp_posts.ID = mt2.post_id)
INNER JOIN wp_postmeta AS mt3 ON (wp_posts.ID = mt3.post_id)
INNER JOIN wp_postmeta AS mt4 ON (wp_posts.ID = mt4.post_id) WHERE 1=1  AND wp_posts.post_type = 'job_listing' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'expired' OR wp_posts.post_status = 'tr_pending' OR wp_posts.post_status = 'tr_failed' OR wp_posts.post_status = 'tr_completed' OR wp_posts.post_status = 'tr_activated' OR wp_posts.post_status = 'private') AND ( (wp_postmeta.meta_key = 'app_trailer-type' OR CAST(wp_postmeta.meta_value AS CHAR) LIKE '%Flatbed%')
OR  (mt1.meta_key = 'app_pay-type' AND CAST(mt1.meta_value AS CHAR) LIKE '%Per Week%')
OR  (mt2.meta_key = 'geo_address' AND CAST(mt2.meta_value AS CHAR) LIKE '%Davenport%')
OR  (mt3.meta_key = 'geo_country' AND CAST(mt3.meta_value AS CHAR) LIKE '%United States%')
OR  (mt4.meta_key = 'geo_short_address' AND CAST(mt4.meta_value AS CHAR) LIKE '%Davenport%') ) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 10

请帮忙。

对于 OR 查询参数数组应该是这样的：

$args = array(
    'post_type' => 'post',
    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key' => 'app_trailer-type',
            'value' => $job_tailor,
            'compare' => 'LIKE'
        ),
        array(
            'key' => 'app_pay-type',
            'value' => $app_pay_type,
            'compare' => 'LIKE'
        ),
        array(
            'key' => 'geo_address',
            'value' => $geo_address,
            'compare' => 'LIKE'
        ),
        array(
            'key' => 'geo_country',
            'value' => $geo_country,
            'compare' => 'LIKE'
        ),
        array(
            'key' => 'geo_short_address',
            'value' => $geo_short_address,
            'compare' => 'LIKE'
        ),
    )
);

参考： http://codex.wordpress.org/Class_Reference/WP_Query

用like更改了参数。

$args = array('post_type' => 'job_listing', 'relation' => 'OR');
$args['meta_query']=array(
    array(
        'key' => 'app_trailer-type',
        'value' => $job_tailor,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'app_pay-type',
        'value' => $app_pay_type,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'geo_address',
        'value' => $geo_address,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'geo_country',
        'value' => $geo_country,
        'compare' => 'LIKE'
    ),
    array(
        'key' => 'geo_short_address',
        'value' => $geo_short_address,
        'compare' => 'LIKE'
    ),
);

你可以

尝试这样的事情

$args = array(
    'post_type' => 'job_listing',
    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key' => 'app_trailer-type',
            'value' => $job_tailor,
            'compare' => 'LIKE'
        ),
        array(
            'key' => 'app_pay-type',
            'value' => $app_pay_type,
            'compare' => 'LIKE'
        ),
        // ....
    )
);

来自WP_Query类参考（链接）：

重要说明：tax_query采用税务查询参数数组（它需要一个数组数组） - 你可以在第二个例子中看到这一点下面。此构造允许您使用第一个（外部）数组中用于描述分类查询之间的布尔关系。

您应该在meta_query数组的开头添加一个array('relation' => 'OR')。
