Hi, is the XHR object work on Diferior ? Because I implement a form with 2 select lists with an AJAX method, if you dont know what ajax is, it means Asynchronous JAvascript Xml, for resume, it allow you to make some asynchronous request on your database for example, that suppose you can make your choice in a list A and immediatly the list B (which is linked) choices appears ... thats great but the XHR cannot send the data to the second page which make the database request ...
Thats the code : (between literal statements)
<?php
include("./static/vod_list.php");
?>
<SCRIPT language="JavaScript">
var l1 = f.elements["list1"];
var l2 = f.elements["list2"];
var index = l1.selectedIndex;
if(index < 1)
l2.options.length = 0;
else {
var xhr_object = null;
if(window.XMLHttpRequest) // Firefox
xhr_object = new XMLHttpRequest();
else if(window.ActiveXObject) // Internet Explorer
xhr_object = new ActiveXObject("Microsoft.XMLHTTP");
else { // XMLHttpRequest non supporté par le navigateur
alert("Votre navigateur ne supporte pas les objets XMLHTTPRequest...");
return;
}
xhr_object.open("POST", "./static/vod_list.php", true);
xhr_object.onreadystatechange = function() {
if(xhr_object.readyState == 4)
eval(xhr_object.responseText);
}
xhr_object.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
var data = "genre_vod="+escape(l1.options[index].value)+"&form="+f.name+"&select=list2";
xhr_object.send(data); // <--- This is the instruction suppose to send the data to vod_list.php
}
And that the code of the second page (vod_list.php) (in the static directory) :
<?php
// in this page smarty cant recognize $_POST["genre_vod"](and the other) because data are not send ...
$query = "SELECT `com_vod` FROM `dif_vod` WHERE `genre_vod` = '".$_POST["genre_vod"]."'";
$query .= " ORDER BY `genre_vod`";
$result = @mysql_query($query);
echo 'var o = null;';
echo 'var s = document.forms["'.$_POST["form"].'"].elements["'.$_POST["select"].'"];';
echo 's.options.length = 0;';
while($r = mysql_fetch_array($result))
echo 's.options[s.options.length] = new Option("'.$r["com_vod"].'");';
@mysql_close();
?>
Any idea about why this doesnt work, I've developped the same code on a asp website in the past and that work fine, I think its unfortunatly due (again) to Smarty or something like that ...

This is not an issue with Diferior. You can't just drag and drop random code and expect it to work.
<?php and ?> tags won't be interpreted as PHP in Smarty (try {php}{/php}), you have to use full (static) URLs everythere (due to URL rewriting) and if that doesn't work, debug every component of your code individually, check browser's error console for any JS errors.
Its not just a drag and drop, I've highly modify this code,plus, I know how smarty works, im not stupid at all, I know you under-estimate me because of my stupid errors everytime im coming back there, but I know what I do and if Im asking you its not for nothing, I just want to know why (even with smarty) all the normal proceed never works on Diferior (such as FCKEditor,Shoutbox,AJAX,and many more ...), I understand that template engine impose special marks, but its not just that, there is something else ...
I've tried yet all {php} / {/php} {literal} / {/literal} tricks, that dont work, with implemented functions, that dont work, why its so difficult ? ....
Well i think Diferior is not enough open for the developpers, you've got to do many tricks to see some result, I know you're alone to assure the support of Diferior, and its not an easy task especially with guys like me, but the almost part of my request are not solved !
Diferior need to be more active (with a staff ?), more updated or else it will be forgetted ...
Today, the web has a lot of new application (forum,ajax,xhtml,shoutbox,tracker,css 2,backend interface ...), why Diferior may not take advantage of that ?
For now, I have got no more JS errors, but that still dont work, my problem is the SQL request seems to be executed because if I choose a 3 movies category for example, the second list is showed with 3 lines, with 5 movies category, it appear with 5 lines, BUT lines are empty ...
I've tried to send static argument and that work, its just with the SQL request result showing, in this case that dont want, maybe its the way I collect results from the SQL request :
$result = mysql_query($query);
while ($row = mysql_fetch_array($result)) {
echo 's.options[s.options.length] = new Option("'.$result['id_vod'].'","'.$result['com_vod'].'");';
}

And that the code of the second page (vod_list.php) (in the static directory) :

For example : while($variable = mysql_fetch_array($blabla)) { echo $variable['abc']}
Curiously, Diferior dont like this, but with this code that work :
$result = mysql_query($query)or die('Erreur SQL !<br>'.$query.'<br>'.mysql_error()); for ($i=; $i<mysql_num_rows($result); ++$i){ echo 's.options[s.options.length] = new Option("'.mysql_result($result,$i, 3)).'","'.mysql_result($result,$i, ).'");'; }
Maybe mysql_fetch_array is not supported ...?

Well, the problem is resolved, if there are any while ($data=mysql_fetch_array($query)){} loop structure in the website, can you tell me where ?
