禁止wordpress用户上传一些特定后缀的文件，和修改文件上传容量限制

Posted by On 四月 28, 2014 1 Comment

不管从安全考虑还是说从网站流量等考虑，限制用户上传一些特定后缀比如exe还是很有必要的。干货方法，在当前主题的functions添加如下代码：

  1. add_filter(‘upload_mimes’, ‘custom_upload_mimes’);
  3. function custom_upload_mimes( $existing_mimes=array() ) {
  4.   // 注意中括号中的名称，必须取自上面支持列表中中括号的名称
  5.   unset( $existing_mimes[‘exe’] ); //此处禁止了上传exe后缀名的可运行文件

unset( $existing_mimes[‘htm|html’] ); //此处禁止了上传html和htm后缀名的压缩文件

  1.   return $existing_mimes;
  2. }

如果想修改文件上传大小，方法如下：

在根目录新建一个php.ini文件，添加以下代码

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

 

如果是apache服务器可以在.htaccess文件添加以下代码：

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300

 

如果想更大，只需将64M改为你想要的大小。
