need help with refresh php

[dezkit]

i have this php code

<?php
session_start();
session_register("count");
$sessid = session_id();
if (!isset($_SESSION)) 
{
$_SESSION["count"] = 0;
echo "<p>Counter initialized</p>\n";
} 
else {
       $_SESSION["count"]++; }
         echo "<p>The counter is now <b>$_SESSION[count]</b></p>";
  echo "<p>please reload this page to increment</p>";
?>

Click <a href="javascript:function?">here</a> to refresh the page.

 

And i was wondering so that if somebody presses "here" the counter adds by one without the browser refreshing, thanks and please post back

You would need ajax to send the request to the same or a different page, and then update the result on your page.

 

It would be easier to refresh the page, than to use ajax to add to the session counter...

[dezkit]

can you or somebody give me the ajax code please?

[xtopolis]

//CREATES A XMLHttpRequestObject
function newXHRO()
{
  try { return new XMLHttpRequest(); } catch(e) {}
  try { return new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) {}
  try { return new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {}
  alert("XMLHttpRequest not supported");
  return null;
}

//Make call  (pass the function an id
function updateCtr(what)
{
  var x = document.getElementById(what);
    x.innerHTML = 'Updating...';

  var XHRO = new newXHRO();
  var url = 'scriptname.php';  // CHANGE THIS TO YOUR URL
  
  XHRO.onreadystatechange=function()
  {
    if(XHRO.readyState==4 && XHRO.status==200)
    {
      x.innerHTML = XHRO.responseText;
    }
  }
  
  XHRO.open("GET",url,true);
  XHRO.send(NULL);
}

Whoa! thats a wall of text

 

Can you put that in my code? Thanks sooo much, im not that professional at ajax/php

[xtopolis]

No I won't code it for you :3

 

You're welcome.

(I told you it would be easier to just refresh the page.)

[dezkit]

what? lol.

 

<?php
session_start();
session_register("count");
$sessid = session_id();
?>
<script language="javascript" type="text/javascript">
<!-- 
function newXHRO()
{
  try { return new XMLHttpRequest(); } catch(e) {}
  try { return new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) {}
  try { return new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {}
  alert("XMLHttpRequest not supported");
  return null;
}
//Make call  (pass the function an id
function updateCtr(what)
{
  var x = document.getElementById(what);
    x.innerHTML = 'Updating...';

  var XHRO = new newXHRO();
  var url = 'test1.php';  // CHANGE THIS TO YOUR URL
  
  XHRO.onreadystatechange=function()
  {
    if(XHRO.readyState==4 && XHRO.status==200)
    {
      x.innerHTML = XHRO.responseText;
    }
  }
  
  XHRO.open("GET",url,true);
  XHRO.send(NULL);
}
//-->

</script>


<?php
if (!isset($_SESSION)) 
{
$_SESSION["count"] = 0;
echo "<p>Counter initialized</p>\n";
} 
else {
        $_SESSION["count"]++; }
          echo "<p>The counter is now <b>$_SESSION[count]</b></p>";
  echo "<p>please reload this page to increment</p>";
?>

Click <a href="javascript:updateCtr(what)">here</a> to refresh the page.

 

is this corerct?

[web_loone_08]

that is your ajax code - that xtopolis just provided you:

 

//CREATES A XMLHttpRequestObject
function newXHRO()
{
  try { return new XMLHttpRequest(); } catch(e) {}
  try { return new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) {}
  try { return new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {}
  alert("XMLHttpRequest not supported");
  return null;
}

//Make call  (pass the function an id
function updateCtr(what)
{
  var x = document.getElementById(what);
    x.innerHTML = 'Updating...';

  var XHRO = new newXHRO();
  var url = 'scriptname.php';  // CHANGE THIS TO YOUR URL
  
  XHRO. />  {
    if(XHRO.readyState==4 && XHRO.status==200)
    {
      x.innerHTML = XHRO.responseText;
    }
  }
  
  XHRO.open("GET",url,true);
  XHRO.send(NULL);
}

 

put your php script in a different page and name it "scriptname.php" (for example purposes only - name it what you want to; just make sure you define the "url" variable in the AJAX script above; with the same name).

 

<?php
session_start();
session_register("count");
$sessid = session_id();
if (!isset($_SESSION)) 
{
$_SESSION["count"] = 0;
echo "<p>Counter initialized</p>\n";
} 
else {
        $_SESSION["count"]++; }
          echo "<p>The counter is now <b>$_SESSION[count]</b></p>";
  echo "<p>please reload this page to increment</p>";
?>

 

then in your html page; if your calling the function with link - do it something like this:

 

<span id="counter"></span>

Click <a href="javascript:updateCtr('counter')">here</a> to refresh the page.
