AJAX unspecified error

[maverick5x]

Hello all

 

i have this function

client = createXMLObject();
	var params = "username="+Username+"&password="+Password;
	client.setRequestHeader("Content-Type", "text/plain");
	client.open("POST","login.php",true);
	client.onreadystatechange = updateLogin;
	client.send(params);

 

and it gives an error in the line where i setRequestHeader "unspecified error".

I am reading a tutorial and this code was in it. so what can be the problem?

 

Thanks in advance

i never set request header, try remove that line and see what happens

[maverick5x]

in the login.php

 

all i do is print

echo $_POST["username"]."<BR>".$_POST["password"];

 

The problem is, nothing gets posted and this echo line doesnt print anything apart from the <BR>

Your post data do not get populated into $_POST.

it got captured in $HTTP_RAW_POST_DATA, and you need to populate this data by hand.

Hmm, Can you show me how to do that please? I think that $_POST is readonly but i will try this

while(list($Col,$Val)=each($HTTP_RAW_POST_DATA))
{
$_POST[$Col] = $Val;
}

 

would that work?

$_POST=$HTTP_RAW_POST_DATA;

Thanks to a guy called "Dashiva" in "javascript" channel on some IRC server .

 

He pointed out the problem by saying: "Duh, you dont set the header before calling open()" so i moved the header setting to the line just after calling open() method and it worked. Without even using $HTTP_RAW_POST_DATA.

 

here is the result:

client = createXMLObject();
var params = "username="+Username+"&password="+Password;
client.open("POST","login.php",true);
client.setRequestHeader("Content-Type", "application/x-www-form-urlencoded ");
client.onreadystatechange = updateLogin;
client.send(params);

thanks for sharing, that's new to me too.

I used to populated the HTTP_RAW_POST_DATA myself
