Where can you edit files?

Hosts differ in what they let you touch. Generate the format you can actually use — and if the first one silently does nothing, that usually means your host overrides it, so try the next.

Resulting upload limit

settings

wp-config.php can raise WordPress's own memory limit, but it cannot raise PHP's upload_max_filesize — that is a PHP directive, not a WordPress one. If your host locks PHP settings, no amount of wp-config editing will change the upload cap, and you will have to ask them.

關於Max Upload Size Fixer

WordPress upload limits are set in three places that must agree: upload_max_filesize, post_max_size, and memory_limit. Set your target size and this emits all three, correctly ordered, for php.ini, .htaccess, and wp-config.php.

FAQ

常見問題

我調高了 upload_max_filesize，卻什麼都沒變。為什麼？

因為 WordPress 取的是三個值裡「最小」的那一個：upload_max_filesize、post_max_size 和 memory_limit。只調高其中一個，另一個卻維持很低，什麼都不會改變。post_max_size 必須比 upload_max_filesize 大，因為請求主體裝的是檔案，加上包在它外面的表單。

wp-config.php 能調高上傳上限嗎？

只能部分做到，而且這一點讓很多人卡住。wp-config.php 可以調高 WordPress 的記憶體上限，但 upload_max_filesize 是一個 PHP 參數，等到 WordPress 載入時，PHP 通常早就把它讀完了。如果你的主機把 PHP 設定鎖死，那再怎麼編輯 wp-config 都改不了這個上限。

我的主機不讓我編輯 php.ini。那該怎麼辦？

試試在你的網頁根目錄放一個 .user.ini 檔案——許多共享主機會讀取它。如果連這也不行，那這個上限就是在你的帳號之上被強制執行的，只有你的主機商能更改。去問他們吧；這通常只是一張改一行設定的工單。
