.htaccess網址重寫挑戰與查詢

Question

有一點挑戰。我無法在當前的重寫代碼中添加另一個「過濾器」。我想補充另一個重寫，在該URL的末尾捕捉查詢字符串（如果提供）

例..

example.com/search/?sort=newest --> example.com/search.php?sort=newest 
example.com/search/first?sort=newest --> example.com/search.php?a=first&sort=newest 
example.com/search/first/second?sort=newest --> example.com/search.php?a=first&b=second&sort=newest 
example.com/search/first/second/third?sort=newest --> example.com/search.php?a=first&b=second&c=third&sort=newest 

這是我當前的代碼。

# search without filters 
RewriteRule ^search?$ search/ [NC,L] 

# search with one filter 
RewriteRule ^search/([A-Za-z0-9-+]+)?$ search.php?a=$1 [NC,L] 

# search with two filters 
RewriteRule ^search/([A-Za-z0-9-]+)/([A-Za-z0-9-+]+)?$ search.php?a=$1&b=$2 [NC,L] 

# search with three filters 
RewriteRule ^search/([A-Za-z0-9-]+)/([A-Za-z0-9-]+)/([A-Za-z0-9-+]+)?$ search.php?a=$1&b=$2&c=$3 [NC,L] 

Answer 1

要保留RewriteRule中的現有查詢字符串，您不需要執行任何操作。

但是，如果你在替換部分自己添加查詢字符串，您需要使用QSA標誌追加以前的查詢字符串

RewriteRule ^search/([A-Za-z0-9-+]+)?$ search.php?a=$1 [NC,L,QSA]
