Question

我在functions.php中构建了一个自定义帖子，可以在admin中正常工作。现在我想使用ajax从另一个php文件手动创建自定义帖子。在functions.php中我得到了这样的东西：

add_action('save_post', 'save_reference');

function save_reference(){
    global $post;
    update_post_meta($post->ID, "company", $_POST["company"]);
    update_post_meta($post->ID, "contact", $_POST["contact"]);
    update_post_meta($post->ID, "address", $_POST["address"]);
    update_post_meta($post->ID, "zipcode", $_POST["zipcode"]);
    update_post_meta($post->ID, "town", $_POST["town"]);
    update_post_meta($post->ID, "phone", $_POST["phone"]);
    update_post_meta($post->ID, "mobile", $_POST["mobile"]);
    update_post_meta($post->ID, "email", $_POST["email"]);

    global $wpdb;
    $wpdb->query("UPDATE $wpdb->posts
SET post_title = '$post->ID'
WHERE ID = $post->ID");

}

那个用post_metas设置保存帖子，然后将帖子标题更新为实际的post_id。

我已经设置了ajax工作，此时我手动设置所有$ _POST值。在我的ajax中（在functions.php中设置较低）我尝试调用save_reference（）;但没有任何反应。我有这样的事情：

$_POST['company'] = $json_array2[0];
$_POST['contact'] = $json_array2[1];
$_POST['address'] = $json_array2[2];
$_POST['zipcode'] = $json_array2[3];
$_POST['town'] = $json_array2[4];
$_POST['phone'] = $json_array2[5];
$_POST['mobile'] = $json_array2[6];
$_POST['email'] = $json_array2[7];

$_POST['post_type'] = 'reference';
$_POST['content'] = 'test content';

save_reference();

我不想用wp_query保存数据，因为我希望能够调用save_reference（）;因为它应该做的伎俩。我尝试了wp_insert，但没有成功。请帮帮我。

编辑我的解决方案：在我使用的ajax中：

global $post;
$post_ID = wp_insert_post(array('post_type' => 'reference', 'post_status' => 'publish', 'post_content' => "$_POST[content]"));
$post = get_post($post_ID);
save_reference();

以下示例修复了示例代码的一些问题。问题：

您未正确处理修订后的内容
您正在通过更新数据库中的post_title方向来绕过操作并过滤挂钩
将值设置为$_POST通常不赞成
使用键控数组而不是整数索引可以更轻松地获取值，并允许将JSON替换为$_POST。
仅当标题不等于ID时才更新帖子，因为数据库更新很昂贵。

这是一个与WordPress＆＃39;建议。

// The save_post action will only pass in a $post_id, so we know it was AJAX if $json!=false
function save_reference( $post_id, $json=false ){
    //verify post is not a revision
    if ( $parent_id = wp_is_post_revision( $post_id ) ) 
        $post_id = $parent_id;

    // post we just saved
    $post = get_post( $post_id );

    // only update the post if we need to since it's expensive
    if ( $post->post_title != $post_id ){
        // since we are going to update this post, we have to unhook to prevent a loop
        remove_action( 'save_post', 'save_reference' );

        // the data we want to update, set the post_title to the ID
        $update = array(
            'ID' => $post_id,
            'post_title' => $post_id,
        );
        wp_update_post( $update );

        // rehook since we DO want this method to be called if something else updates
        add_action( 'save_post', 'save_reference' );
    }

    // since we gave the $json key values we can use it in place of $_POST
    $input = ( $json )? $json : $_POST;

    update_post_meta( $post_id, "company", $input["company"] );
    update_post_meta( $post_id, "contact", $input["contact"] );
    update_post_meta( $post_id, "address", $input["address"] );
    update_post_meta( $post_id, "zipcode", $input["zipcode"] );
    update_post_meta( $post_id, "town", $input["town"] );
    update_post_meta( $post_id, "phone", $input["phone"] );
    update_post_meta( $post_id, "mobile", $input["mobile"] );
    update_post_meta( $post_id, "email", $input["email"] );  
}
add_action( 'save_post', 'save_reference' );

以下是对save_reference()函数的调用从您的AJAX中看起来的样子

// This could be done elsewhere if use a key instead if integer index for the array
$json = array(
    'company' => $json_array2[0],
    'contact' => $json_array2[1],
    'address' => $json_array2[2],
    'zipcode' => $json_array2[3],
    'town' => $json_array2[4],
    'phone' => $json_array2[5],
    'mobile' => $json_array2[6],
    'email' => $json_array2[7],
    'post_type' => 'reference', // not sure what this is for?
    'content' => 'test content', // not sure what this is for?
);
$post_id = // ??? you need to pass in a post_id with your AJAX call
save_reference( $post_id, $json );

Wordpress从另一个函数调用自定义post save_post动作
