我按当前用户的名字保存帖子。此外,我将数组对象 - $ganalytics_settings
- 保存到自定义字段中的帖子。使用以下代码,我尝试加载用户名的数组,具有特定的帖子标题:
function get_custom_field_for_current_user( $customFieldName ) {
$current_user = wp_get_current_user();
global $wpdb;
$id = $wpdb->get_row("SELECT ID FROM wp_posts WHERE post_title = '" . $current_user->user_login . "' && post_status = 'draft' && post_type = 'post' ", 'ARRAY_N');
return get_post_meta((int)$id[0], $customFieldName);
}
但是,我要回到以下对象:
相反,我想取回以下内容:
为什么我的函数给了我一个数组中的数组的任何建议?
感谢您的回复!

我不知道我是否理解你,但是如果你的函数返回第一个键是数组的数组,那么只需要总是返回第一个键
/** adds a tooltip to a specified element, like an event or resource */
function addToolTip(element, o, target, hideEvents) {
if (target === undefined || target === null) {
target = false;
}
if (hideEvents === undefined) {
hideEvents = "mousedown mouseup mouseleave";
}
element.qtip({
content: {
title: o.title,
text: o.text
}
, position: {
my: "bottom center",
at: "top center",
target: target // "mouse" is buggy when dragging and interferes with clicking
//adjust: { y: -9}
}
, style: {
tip: { corner: 'bottom center' },
classes: 'qtip-light qtip-shadow'
},
show: {
effect: function () {
$(this).fadeTo(300, 1);
},
solo: true,
delay: 200
},
hide: {
effect: true,
event: hideEvents // otherwise stays while dragging
}
});
}

函数get_post_meta
具有以下签名get_post_meta ( int $post_id, string $key = '', bool $single = false )
。如果$single
为false,则返回值为数组。如果$single
为真,则将是元数据字段的值。
试试这个:
function get_custom_field_for_current_user( $customFieldName ) {
$current_user = wp_get_current_user();
global $wpdb;
$id = $wpdb->get_row("SELECT ID FROM wp_posts WHERE post_title = '" . $current_user->user_login . "' && post_status = 'draft' && post_type = 'post' ", 'ARRAY_N');
return get_post_meta((int)$id[0], $customFieldName, true);
//^ Here to return single value
}
