Question

I'm writing a WordPress plugin which uses the settings API from within a class. So the class calls register_settings(), add_settings_field(), and add_settings_section() from within the class which is working well except when I try to submit the form a get a server error with the following error in my logs:

AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

My WordPress install is a bit weird. It's based on Mark Jaquith's WordPress Skeleton repo and I have moved my wp-content folder, my wp-config.php file outside WordPress.

I am also running WordPress through Vagrant so it might be a server config issue. However, I just tried to use my plugin in VVV using a standard WordPress install and its working perfectly.

My WordPress directory looks like this (composer install WP to the app dir):

index.php
wp-config.php
wp-content/
app/

I have added my rewrite logs in a paste bin: http://pastebin.com/QKCFjULZ

My .htaccess file looks like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]


RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) /app/$2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ /app/$2 [L]


RewriteRule . /index.php [L]

Options -indexes
</IfModule>
# END WordPress

Answer 1

由于这些规则，您有重定向循环

RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) /app/$2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ /app/$2 [L]

实际上，您必须记住，即使重写后您的规则也会被评估。因此，如果您有/something/wp-xxx/yyy/zzz，则会在内部将其重写为/app/wp-xxx/yyy/zzz。但现在，正如您所看到的，您的规则将再次与新的uri /app/wp-xxx/yyy/zzz匹配。

证明，查看您的日志

applying pattern '^([_0-9a-zA-Z-]+/)?(wp-.*)' to uri 'wp-admin/network/options.php',
rewrite 'wp-admin/network/options.php' -> '/app/wp-admin/network/options.php',

然后你有

applying pattern '^([_0-9a-zA-Z-]+/)?(wp-.*)' to uri 'app/wp-admin/network/options.php',
rewrite 'app/wp-admin/network/options.php' -> '/app/wp-admin/network/options.php',

它一直持续......直到10次重定向的限制

要避免此行为，您需要对规则添加一些限制，以确保在不需要时不会对其进行评估。一个简单的解决方法是使用负前瞻模式来确保当前请求在重写之前不以/app/开头：

RewriteRule ^((?!app/)[^/]+/)?(wp-.+)$ /app/$2 [L]

最后，你的htaccess看起来像这样

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]

# Rule 1
RewriteRule ^([^/]+/)?files/(.+)$ wp-includes/ms-files.php?file=$2 [L]

# Rule 2
RewriteRule ^((?!app/)[^/]+/)?(wp-.+)$ /app/$2 [L,QSA]

# Rule 3
RewriteRule ^((?!app/)[^/]+/)?(.+\.php)$ /app/$2 [L,QSA] 

RewriteRule ^ index.php [L]

Options -Indexes
</IfModule>
# END WordPress

提醒：3条规则仅在不存在的文件/文件夹上执行。

示例：

http://domain.tld/files/something或 http://domain.tld/xxx/files/something将在内部重写感谢规则1

/wp-includes/ms-files.php?file=something

规则2，

http://domain.tld/wp-something/somethingelse或http://domain.tld/xxx/wp-something/somethingelse（其中xxx可以是除app之外的任何内容）将在内部重写为/app/wp-something/somethingelse

规则3，

http://domain.tld/file.php或http://domain.tld/xxx/file.php（其中xxx可以是除app之外的任何内容）将在内部重写为/app/file.php
