WordPress 轉址與中文網址在 IIS 上會遇到的 404 問題

以下包含暫時解法，因為是直接動WordPress Kernel

1. WordPress 網址無法轉址（Permalinks）

要修改 web.config 檔

<?xml version="1.0" encoding="UTF-8"?>

<configuration>

 <system.webServer>

 <rewrite>

 <rules>

 <rule name="wordpress" stopProcessing="true">

 <match url=".*" />

 <conditions logicalGrouping="MatchAll">

 <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />

 <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />

 </conditions>

 <action type="Rewrite" url="index.php" />

 </rule>

 </rules>

 </rewrite>

 </system.webServer>

</configuration>

2. WordPress 中文網址無法正常轉址

修改 wp-includes/ 底下的 class-wp.php

$pathinfo = isset( $_SERVER['PATH_INFO'] ) ? $_SERVER['PATH_INFO'] : '';

改成

$pathinfo = isset( $_SERVER['PATH_INFO'] ) ? mb_convert_encoding( $_SERVER['PATH_INFO'], 'UTF-8', 'Big5') : '';

然後

list( $req_uri ) = explode( '?', $_SERVER['REQUEST_URI'] );

改成

list( $req_uri ) = explode( '?', mb_convert_encoding( $_SERVER['REQUEST_URI'], 'UTF-8', 'Big5' )  );

3. WordPress 中文檔案上傳錯誤
修改 wp-admin/includes/ 底下的 file.php

$filename = wp_unique_filename( $uploads['path'], $file['name'], $unique_filename_callback );

改成

$fileTypeNameArr = explode( '.', $filename );
$countNum = count( $fileTypeNameArr ) - 1;
$fileExt = $fileTypeNameArr[$countNum];
$filename = time() . '-' . rand( 0,999999999 ) . '.' . $fileExt;
