我有一个模板从db中选择wordpress post变量并将它们加载到我设计的html模板上。 我想要的是让用户选择他们喜欢的文章然后将选择提交给模板，该模板将实习成为时事通讯。
到目前为止，我有代码从数据库中查看数据并将其排列在我的模板中。代码如下：
<?php /*
Template Name: News Selector Template
*/
//Pull the data
$posts = $wpdb->get_results
("
SELECT
p1.*,
wm2.meta_value
FROM
mp_posts p1
LEFT JOIN
mp_postmeta wm1
ON (
wm1.post_id = p1.id
AND wm1.meta_value IS NOT NULL
AND wm1.meta_key = '_thumbnail_id'
)
LEFT JOIN
mp_postmeta wm2
ON (
wm1.meta_value = wm2.post_id
AND wm2.meta_key = '_wp_attached_file'
AND wm2.meta_value IS NOT NULL
)
WHERE
p1.post_status='publish'
AND p1.post_type='post'
ORDER BY
p1.post_date DESC LIMIT 0,30
");
?>

1) Padding is only placed on the top and/or bottom of the div. The elements within this div have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.

我想知道的是我如何在循环中提交包含数据项（post_title，post_excerpt，meta_value，guid）的数组。
答案 0 :(得分：0)
使用隐藏输入，并将数组内插到输入
中<input type="hidden" name="metas" value="<?php echo implode(',', $posts);?>">
然后在后端，您可以使用explode来检索值：
$posts = explode(',', $_POST['metas']);
