[resolved] Call php code with Query String (2 posts)

    Greetings,

    I have a wordpress page that contains custom php code.
    Let's say the page name is called myphpcode.
    I have a url that looks like: http://www.mysite.com/myphpcode/var1-var2-var3
    The var1-var2-var3 is meant to be a hyphen delimited parameter list
    that the myphpcode program will parse as a query string.

    The wordpress site is using a permalinks setting: /%postname%/
    Thus the other links for posts look like:
    http://www.mysite.com/category/my-first-topic
    http://www.mysite.com/category/my-second-topic
    http://www.mysite.com/top-ten-holiday-gift-ideas

    So, in this example, I am assuming
    my-first-topic and top-ten-holiday-gift-ideas
    function like an html file.

    When I call http://www.mysite.com/myphpcode
    the code runs OK and a default page is displayed since it has not
    yet received any query string values.

    When I call http://www.mysite.com/myphpcode/var1-var2-var3
    wordpress says The page you requested could not be found.

    I am using the following .htaccess

    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^myphpcode/(.*)$ http://www.mysite.com/myphpcode?parm1=$1 [QSA,L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]

    I was hoping the RewriteRule with the myphpcode reference
    would execute the myphpcode and pass the var1-var2-var3 as a query string into parm1. I am guessing that it sees the myphpcode as a wordpress category instead of a wordpress page with php code and that it sees the var1-var2-var3 as html code which of course it is not.

    Since I am relatively new to wordpress I am in need of some
    more experienced eyes.

    Thank You.

    I found the solution to using a URL such as
    http://www.mysite.com/myphpcode/var1-var2-var3 in a wordpress
    page containing custom php code and custom permalinks such as
    /%postname%/

    The solution is described here:
    http://www.rlmseo.com/blog/passing-get-query-string-parameters-in-wordpress-url/

    If you read this you will see that you need to update two php mpodules.
    You must change functions.php located in the root folder for the specific wordpress theme you are using. The other module to change would be your own custom php code where you want to interpret the URL that has just been pressed. Note: In my situation, myphpcode is a program that keeps getting called with different values in the query string. My program, myphpcode, knows how to interpret these query string values because it created the href links in the first place.

    Thus, in my example, http://www.mysite.com/myphpcode/var1-var2-var3

    myphpcode is a wordpress Page that contains my custom php code and
    var1-var2-var3 is acting as a query string.

    The problem was that wordpress did not recognize this URL.
    By default I believe it tried to interpret myphpcode like
    category in a standard wordpress URL with a Post called my-first-topic.
    For example, http://www.mysite.com/category/my-first-topic
    is a standard structure for many wordpress posts.

    I wanted wordpress to recognize myphpcode as a wordpress page containing php code. This can be accomplished using the add_rewrite_rules function described at http://www.rlmseo.com/blog/passing-get-query-string-parameters-in-wordpress-url/

    Here is the complete code as it relates to the URL I have been describing: http://www.mysite.com/myphpcode/var1-var2-var3

    [Code moderated as per the Forum Rules. Please use the pastebin]

    In any event, the code added to functions.php did help define my URL with my program and query string to wordpress. I was then able to get the pagename and query string from $_SERVER["REQUEST_URI"]

    The wordpress site that is actually using this code can be viewed at

    http://babynamesdiary.com/baby-names-and-meanings/baby-names-A-1/

    In this URL, baby-names-and-meanings is a wordpress page containing my custom php code and baby-names-A-1 is the query string.
    The customer for whom I created this application wanted the URL this way for SEO purposes. Hope this helps. Buona Fortuna!
