Mar 13th, 2008

Is there any way to count users in my chatroom and display whos chatting using javascript or ajax? code in php below has issues, but this is what it should do.

<span class="ad_notxt"><code class="inlinecode"><?php
 
 
$chatnames = file('http://client11.addonchat.com/scwho.pl?id=292747&plain=1');
$indx = count($chatnames);
$indxcom = $indx - 1;
if ($indx == 0) {
echo "<b>No one is in the chat room at the moment</b>";
}
else{
echo "<b>People Chatting:</b>&nbsp;&nbsp;";
 for($i = 0; $i < $indx; $i++) {
 $name = explode('	', $chatnames[$i], 2);
echo " $name[0]";
 if ($i < $indxcom) {
    echo ", ";
}  
 
  }
}
 
?>
</code></span>
<span class="ad_notxt"><code class="inlinecode"><?php


$chatnames = file('http://client11.addonchat.com/scwho.pl?id=292747&plain=1');
$indx = count($chatnames);
$indxcom = $indx - 1;
if ($indx == 0) {
echo "<b>No one is in the chat room at the moment</b>";
}
else{
echo "<b>People Chatting:</b>&nbsp;&nbsp;";
 for($i = 0; $i < $indx; $i++) {
 $name = explode('	', $chatnames[$i], 2);
echo " $name[0]";
 if ($i < $indxcom) {
    echo ", ";
}  

  }
}

?>
</code></span>

I was not able to use php on my website software directly so I was hoping to to remotely host this code and display the data by using an iframe sourced from the remote file, however various issues arose.
could I do the same thing with ajax or javascript?

SetInnerHTMLFromAjaxResponse('your_php_page.php?results=membernames', 'results');

The above expects HTML output from a page, not JavaScript output as given in the PHP function.

The original post also mentions having the PHP file on a different domain. AJAX via the XMLHttpRequest object requires that the files be on the same domain. (At least untill cross domain XMLHttpRequest becomes implemented in all browsers as per the W3C specifications)

A workable solution would have be to use "JavaScript Remoting". You can include a JavaScript file after the page has loaded.

Simple example being:

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
document.write('<script type="text/javascript" src="http://example.com/your/remote/file.php"></script>');
document.write('<script type="text/javascript" src="http://example.com/your/remote/file.php"></script>');

The src attribute would be your remote PHP file. It would have to return a JavaScript function call, as it currently does in your PHP script.

PS: you can also use "Iframe Remoting" which is similar but uses Iframes instead. That is limited to JavaScript function calls also because of the "same origin policy" in effect in XMLHttpRequest also.
