我已经向自定义用户元字段添加了一个值。之后,我试图删除要使用ajax代码删除的自定义元字段。
<form id="um_form" method="POST">
<p>
<label for="um_key">
User Meta Value:
<input type="text" name="um_key" id="um_key" value="<?php echo get_the_id()" style="width:100%;" />
</label>
<input type="submit" value="Submit" />
</p>
</form>
然后复制所有内容并通过stackoverflow
完成仅更改是在更新字段停止工作后的更新字段。
下面是我如何通过wordpress查询获取值的方法。
get_post_meta( $post_id, "_post_like_count", true );
functions.php代码是
function um_modifications_callback() {
// Ensure we have the data we need to continue
if( ! isset( $_POST ) || empty( $_POST ) || ! is_user_logged_in() ) {
// If we don't - return custom error message and exit
header( 'HTTP/1.1 400 Empty POST Values' );
echo 'Could Not Verify POST Values.';
exit;
}
$user_id = get_current_user_id(); // Get our current user ID
$um_val = sanitize_text_field( $_POST['first_name'] ); // Sanitize our user meta value
$um_user_email = sanitize_text_field( $_POST['user_email'] ); // Sanitize our user email field
update_user_meta( $user_id, '_post_like_count', $um_val ); // Update our user meta
wp_update_user( array(
'ID' => $user_id,
'user_email' => $um_user_email,
) );
exit;
}
add_action( 'wp_ajax_nopriv_um_cb', 'um_modifications_callback' );
add_action( 'wp_ajax_um_cb', 'um_modifications_callback' );
