Hello,

I have a task01 function. I would like that the click on the button, does not refrest hte page. I does not work...

Here is the code:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
  

 
  
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

 
<body>

 
 
 <?php
function task01() {
   $logfile2    = 'file.txt';
   $fp = @fopen($logfile2,'a+') or die('ERROR: Can\'t write to the log file ('.$logfile.'), please make sure this file exists and is CHMOD to 666 (rw-rw-rw-)!');
   
 flock($fp, LOCK_EX);
   // fputs($fp, $_POST[name]);
  //  fputs($fp, $_POST[nachricht]);
    fwrite($fp, "\r\n" );
    fwrite($fp, "_______________________\r\n" );
    fwrite($fp, "$datum\r\n");
    fwrite($fp, "Number of lines: $numLines\r\n");
    fwrite($fp, "Message envoye a $tag, $zeit der $datum.\r\n");
    fwrite($fp, "$_POST[name] \r\n");
    fwrite($fp, "$_POST[nachricht] \r\n");
    flock($fp, LOCK_UN);
    fclose($fp);
 }

?>
 
 <? // ### click button01 ?>
<form action="../ausgabe.php" method="post" name="textmail">
<table border=0 cellspacing=2 cellpadding=0 width=100%>
<tr><td nowrap align=right>Your name:</td><td>&nbsp;</td>
<td width=100%><input type="text" name="name" size=50 maxlength=120 value="<?php echo $from_name; ?>"></td></tr>
<tr><td nowrap align=right>Your E-Mail adress:</td><td></td>
<td width=100%><input type="text" name="email" size=50 maxlength=120 value="<?php echo $from_mail; ?>"></td></tr>
<tr><td nowrap align=right>Subject:</td><td></td>
<td width=100%><input type="text" name="betreff" size=50 maxlength=120 value="<?php echo $mail_subject; ?>"></td></tr>
<tr><td nowrap align=right valign=top>Content:<br><i>(max. 1.000 chars)</i></td><td></td>
<td width=100%><textarea cols="40" rows="10" name="nachricht"><?php echo $mail_text; ?></textarea></td></tr>
<tr><td></td><td></td><td>
<input type="hidden" value="1" name="s">
<input type="submit" value="Send your message." name="submit">
</td></tr>
</table>
</form>
 
 
 <? // ### click button02 ?>
<form action="task01" method="post" name="textmail">
    <input type="submit" value="Click here." name="task01">
</form>




</body>
</html>

only problem is by the time you click on the link all the php is done executing,that being said it would be easier said then done

PHP can't function without refreshing the page, as it runs on the server, not the client machine. However, with Ajax, Javascript is used to send a request to a script on the server, then process the response. It is usually used to update part of a page without having to refresh the whole page, but could probably achieve what you're wanting here.

Perhaps they mean they don't want the form fields reset. If so sticky form using php?

I just wanted at the click of the button, one single part fo the page is changed. Damn after PHP, seems that I got to learn java now

Not necessarily, or at least not too much. There are toolkits such as Sajax that allows you to script in PHP, with the Ajax/JavaScript code created automatically.

It is not quite necessary to learn Java. PHP + Ajax can create
'non refreshing' pages updates

I 'ajaxified' pages developed in PHP without many changes. There are some documents around on the internet which suggest to refresh each and every DOM element in your page leaning heavily on Javascript. Not so. Be sure to read all pages about Ajax on the web site below.
