所以，我想做的是制作一个ajax过滤器，这是过滤器代码的一部分，它基于来自过滤器表单的数据构建$args，然后（不是在这段代码中）它给出查询的结果。
我有3个自定义分类法（及其表单功能）：
-type\\u emp（一个选项来自表单）
-status\\u emp（一个或多个选项来自表单）
-city\\u emp（一个选项来自表单）
问题是：I\'m not able to use them in the WP_Query as filters, since they will match the post even if it doesn\'t have all the terms.
例如，type\\u emp为1，status\\u emp为null，city\\u emp为2
它将返回帖子：
（type\\u emp/status\\u emp/city\\u emp）
帖子1（1/2/3）
帖子2（2/1，4/2）
帖子3（1/4/2）
如您所见，post 3应该是唯一返回的，因为他拥有所有参数。Is there a way to restrict the query like that?
此外，我需要多次匹配status\\u emp，有时需要多个术语，在代码中，我分解字符串以生成一个数组，并将其作为术语放入税务查询中。How to I match posts that have at least one of them?
$args = array(
\'orderby\' => \'date\',
\'order\' => \'DESC\',
\'post_status\' => \'publish\'
);
if ( isset( $_POST[\'typefilter\'] ) && $_POST[\'typefilter\'] !== \'\' ) {
$args[\'post_type\'] = \'post_type_x\';
$args[\'tax_query\'] = array(
array(
\'taxonomy\' => \'type_emp\',
\'field\' => \'id\',
\'terms\' => $_POST[\'typefilter\']
)
);
}
if ( $_POST[\'typefilter\'] == \'\') {
$args[\'post_type\'] = \'post_type_x\';
}
// If two or more options are selected they are sorted below
$query = explode(\'&\', file_get_contents("php://input"));
$params = array();
foreach( $query as $param )
{
list($name, $value) = explode(\'=\', $param, 2);
$params[urldecode($name)][] = urldecode($value);
}
if( isset( $params[\'statusfilter\'] ) && $_POST[\'statusfilter\'] !== \'\' ) {
$args[\'tax_query\'] .= array(
array(
\'taxonomy\' => \'status_emp\',
\'field\' => \'id\',
\'terms\' => $params[\'statusfilter\']
)
);
}
// for taxonomies / categories
if( isset( $_POST[\'cityfilter\'] ) && $_POST[\'cityfilter\'] !== \'\') {
$args[\'tax_query\'] .= array(
array(
\'taxonomy\' => \'city_emp\',
\'field\' => \'id\',
\'terms\' => $_POST[\'cityfilter\']
)
);
}
$query = new WP_Query($args);
很抱歉，如果我的问题有点混乱，但我尽量说清楚。
最合适的回答,由SO网友:benny-ben 整理而成
请尝试以下方法：
$args = array(
\'orderby\' => \'date\',
\'order\' => \'DESC\',
\'post_status\' => \'publish\'
);
if ( isset( $_POST[\'typefilter\'] ) && $_POST[\'typefilter\'] !== \'\' ) {
$args[\'post_type\'] = \'post_type_x\';
$args[\'tax_query\'][0][\'taxonomy\'] = \'type_emp\';
$args[\'tax_query\'][0][\'field\'] = \'id\';
$args[\'tax_query\'][0][\'terms\'] = $_POST[\'typefilter\'];
$args[\'tax_query\'][0][\'operator\'] = \'IN\';
}
if ( $_POST[\'typefilter\'] == \'\') {
$args[\'post_type\'] = \'post_type_x\';
}
// If two or more options are selected they are sorted below
$query = explode(\'&\', file_get_contents("php://input"));
$params = array();
foreach( $query as $param )
{
list($name, $value) = explode(\'=\', $param, 2);
$params[urldecode($name)][] = urldecode($value);
}
if( isset( $params[\'statusfilter\'] ) && $_POST[\'statusfilter\'] !== \'\' ) {
$args[\'tax_query\'][1][\'taxonomy\'] = \'status_emp\';
$args[\'tax_query\'][1][\'field\'] = \'id\';
$args[\'tax_query\'][1][\'terms\'] = $params[\'statusfilter\'];
$args[\'tax_query\'][1][\'operator\'] = \'IN\';
}
// for taxonomies / categories
if( isset( $_POST[\'cityfilter\'] ) && $_POST[\'cityfilter\'] !== \'\') {
$args[\'tax_query\'][2][\'taxonomy\'] = \'city_emp\';
$args[\'tax_query\'][2][\'field\'] = \'id\';
$args[\'tax_query\'][2][\'terms\'] = $_POST[\'cityfilter\'];
$args[\'tax_query\'][2][\'operator\'] = \'IN\';
}
$query = new WP_Query($args);
我还没有测试过它，但理论上它应该可以工作：），告诉我它是否可以工作，或者你是否需要更多的帮助
