如何记住当前点击的网址？ javascript？PHP？

Question

I have a html select list menu,when user select an option he/she is redirected to the page of choice. for example he/she will be redirected to http://example.com/towns/Faizabad below is the selection menu,this acts as a jump menu.

  <select name="cities">
  <option value="towns/Antaliya" id="city1">Antaliya</option>
  <option value="towns/Faizabad" id="city2">Faizabad</option>
  </select>

I need when user(logged/anonymous) selects a city... to add attributed selected, and remember the option for several days until user changes again to another option. I am not good with Javascript/jquery.. i think it can be achived with cookies. Any help will be appreciated.

Answer 1

Correct, you can use a cookie.

setcookie("myTown", $_POST['cities'], time()+3600*48);  // expires in 48 hours

In your form you can use

if(isset($_COOKIE["myTown"])) {
   echo "<option value=\"" . $_COOKIE["myTown"] . "\">Your Town</option>";
}

Or you can redirect them to the town directly, by using

if(isset($_COOKIE["myTown"])) {
   header("Location: http://yoursite.com/towns/" . $_COOKIE["myTown"])
}

You can find more information about cookies here: http://php.net/manual/en/function.setcookie.php

Answer 2

You can use this plug-in http://www.ashishblog.com/blog/jquery-cookie-example/ then set your cookies after cities selection

$('select[name=\'cities\']').change(function(){
$.cookie('city', $(this).val());
});
