Refresh page

[Mike4x4s]

i got this code that stores and updates the coordinates i have clicked on a webpage then reloads the page again but it refreshes the whole screen is there a way to get rid of the flicker and make it look smooth this is the code:

Chatbox frame:

<?php
include "global.php";
include "msgdel.php";
?>
<script language="javascript" type="text/javascript">
document.onclick = function(e){
        var e         = e ? e : window.event;
        var x = e.screenX;
        var y = e.screenY;
        document.location = 'nextpage.php?x=' + x + '&y=' + y;
    }
</script>

</HEAD>

<?php
$msgopen = "store/cords/x/$username.txt";
$fh2 = fopen($msgopen, 'r');
$xdata = fgets($fh2);
fclose($fh2);
?>

<?php
$msgopen = "store/cords/y/$username.txt";
$fh2 = fopen($msgopen, 'r');
$ydata = fgets($fh2);
fclose($fh2);
?>

<?php
$msgopen = "store/messages/$username.txt";
$fh2 = fopen($msgopen, 'r');
$msgread = fgets($fh2);
fclose($fh2);
?>
<div align="left">
    <table border="1" cellspacing="0" cellpadding="0" id="table1">
        <tr>
            <td style="position: absolute; left: <?= $xdata ?>; top: <?= $ydata ?>; right: <?= $xdata ?>; bottom: <?= $ydata ?>">
            <image src="images/avatar.gif"><br><image src="images/mod1.gif" width="7" height="14"><span STYLE="background-image: url(images/mod2.gif); width="1" height:14;"><? echo $username; ?></span><image src="images/mod3.gif" width="7" height="14"></span>
<image src="images/msg1.gif" width="7" height="14"><span STYLE="background-image: url(images/msg2.gif); width="1" height:14;"><? echo $msgread; ?></span><image src="images/msg3.gif" width="7" height="14"></span>
            </td>
        </tr>
    </table>
</div>

Nextpage.php

<?
include "global.php";
$x             = $_GET['x'];
$y             = $_GET['y'];
$myFile = "store/cords/x/$username.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = fread($fh, filesize($myFile));
fwrite($fh, $x);
fclose($fh);

$myFile2 = "store/cords/y/$username.txt";
$fh2 = fopen($myFile2, 'w') or die("can't open file");
$stringData2 = fread($fh2, filesize($myFile2));
fwrite($fh2, $y);
fclose($fh2);
header('Location: chatboxframe.php');
?>

anyone?

Can you please rephrase your question? I didn't get it.

[Mike4x4s]

in my code above i want to refresh the page every 2 seconds with no page flicker so it looks all smoothly when it refreshes.

[paul_wilkins]

Instead of refreshing the page every two seconds, you can use Ajax to send data to your server without any refreshing.

[Mike4x4s]

i need to receive it to

[Pepejeria]

You will receive it to with Ajax. You can control if a full reload is smooth or not, that depends on how fast the browser renders the page.

[Mike4x4s]

oh ok what would an example be on that code i have posted above?

[Pepejeria]

You will find tons of Ajax tutorials here.

ok i am a bit confused what ajax can do but what im trying to do is:

i making a chat page and want the page to reload everytime a message is sent out, but i dont want any screen flicking is that possible?

[Pepejeria]

You can refresh the entire page with JavaScript. If the page will flicker or not depends how fast the browser renders the page.

With Ajax you can do a request (get or post) and update only a certain part of the page. Read the Ajax tutorials to better understand how this is done.

[Mike4x4s]

by saying updating only a certain part of the page, would it still flicker, i have seen other php and ajax chats refresh with no flicker and would like to know how it is done, i cant find where to find a code for it.

Here is a tutorial that demonstrates using ajax with php
