need help with php and html form

[jeger003]

hello,

im trying to have a from do a GET on the same page as it was submitted

 

the url is like this mysite.com/index.php?a=34&b=22

 

the form action="" is left blank but it doesn't display a=34b=22 it only displays index.php?informaitonfromform

 

which ends up sending the user to the index page and away from the index.php?a=34&b=22

 

<table width="287" border="1">
  <tr>
    <td width="277"><form id="form1" name="form1" method="GET" action="">
      <label>Zipcode:
      <input type="text" name="zipcode" id="zipcode" />
      </label>
        <input type="submit" name="submit" id="submit" value="Submit" />
    </form>
    </td>
  </tr>
</table>

 

how do i make the submitted form display on this page index.php?a=34&b=22?

change this

action=""

 

to this:

action="<?php echo end(explode("/",$_SERVER['REQUEST_URI'])); ?>"

It didn't work. it continues to forwards me to index.php

 

I'm trying to figure out another way. is there a javascript that can display a textbox when a link is clicked?

 

like my users are sent a page with all the US states and then they click their states and are forwarded to zipcode.

 

i want a textbox to show under the state and they can enter the zipcode that way i can get both state and zipcode in one form
