我当前尝试了以下操作:
$custom_image = usp_get_meta(false, 'usp-custom-4');
$custom_image = htmlspecialchars_decode($custom_image);
$custom_image = nl2br($custom_image);
$custom_image = preg_replace('/<br />/iU', '', $custom_image);
foreach($custom_image as $img) {
echo $img;
}
但我得到
警告:为foreach((提供了无效的论点...
只是一个简单的假设,可以修复它:
更改 $custom_image = preg_replace('/<br />/iU', '', $custom_image);
$custom_image = explode('<br />',$custom_image);
然后您可以循环。
