Htaccess URL-Rewrite的异常行为

Question

I'm using jQuery Autocomplete (fetching values from a database) and displaying results to the user from the database. The search results are clickable and when they click, they are sent to a page called product_display.php with id as the request parameter. Therefore example, it would be something like this :- product_display.php?id=2

On the product_display.php page, there are 3 radio buttons and 3 forms (one for each radio button, the forms open dynamically upon radio select). Each form has a separate submit button. Upon hitting submit, it goes to a different page and the value of a hidden variable named cond is printed.

Everything was working fine until I introduced a Url-Rewrite in my htaccess file, to conver *product_display.php?id=2* to /products/2

When this url-rewrite came into work, the results were not good. As soon as I click the submit button for any form pertaining to any radio button, it again displays the options which were on the product_display page (but header shows different page). How can this be fixed.

jQuery Auto Complete.

<script>
  $(function() {
    function log( message ) {
      $( "<div>" ).text( message ).prependTo( "#log" );
      $( "#log" ).scrollTop( 0 );
    }

    $( "#birds" ).autocomplete({
      source: "search.php",
      minLength: 2,
      select: function( event, ui ) {


        log( ui.item ? "Selected: " + ui.item.value + " aka " + ui.item.label :
          "Nothing selected, input was " + this.actor );
         window.location.href = './products/' + ui.item.value;
         //window.location.href = 'product_display.php?id=' + ui.item.value;
       // document.testForm.action = "pretravel.php?id="+ui.item.value;
        //document.testForm.submit();
      }
    });
  });

htaccess

RewriteRule ^products/(.+)$ product_display.php?id=$1 [L,QSA]

offer_show.php (the page which opens upon clicking submit)

<?php
echo $_REQUEST['cond'];



?>

Answer 1

It's probably a relative/absolute URL thing. Your form has this as its action:

action="offer_show.php"

which means when you go to: /products/123 , the forum gets submitted to /products/offer_show.php , which gets rewritten to /product_display.php?id=offer_show.php .

Try changing the form's action to an absolute URL:

action="/offer_show.php"    

And you may also want to add

<base href="/" />

to your page's header.
