在使用wordpress上传的时候,部分文件类型会遇到“抱歉,由于安全原因,这个文件类型不受支持”的情况。
因为wordpress没有把指定的文件类型加入到允许的mimetype列表中。
wp提供了一个过滤器的钩子“upload_mimes”。这个钩子的作用是筛选允许的mime类型和文件扩展名列表。详见:https://developer.wordpress.org/reference/hooks/upload_mimes/
知道这个钩子的作用后,只需在主题目录下的functions.php里即可。代码如下:
function hzt_add_file_type($mimes = array()) {
$mimes['pdf'] = "application/pdf";
return $mimes;
}
add_filter('upload_mimes', 'hzt_add_file_type');
添加完该代码的效果为允许上传pdf文件。刷新网页后,「管理中心-媒体-媒体库-添加」即可上传pdf文件。
也可以加其他的文件扩展名,常用的文件扩展名列表(mimetype)如下:
