mod_rewrite laravel使用表单get方法

I'm trying to rewrite a URL after submitting a form using the GET method in Laravel. My .htaccess file looks like this:

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

RewriteEngine On

# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]

# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
RewriteRule ^/items/search/(.*)$ /items/search?m_id=%1 [QSA, L]

# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

Having submitted the form the URL still looks like this:

http://127.0.0.1:8000/items/search?m_id=357

Any help with this would be appreciated.

Thanks.

I only just got back round looking into this. In the end I used javascript's onsubmit function to rewrite the URL

onsubmit="window.location.href=this.action + '/' + encodeURIComponent(this.elements['m_id'].value); return false;"
