You're trying to decode an invalid JSON String

I am trying to make an Ext direct call using a script on the server side. Why is this not compliant json?

You're trying to decode an invalid JSON String: <html><body><textarea>{"tid": 1, "action": "api", "type": "rpc", "method": "foo", "result": "hello world"}</textarea></body></html>

Based on this excerpt from the documentation at
http://www.sencha.com/products/extjs/extdirect

I tried wrapping quotes with slashes and got the same result.

This response will be JSON encoded. The router can send back multiple transactions within a single response enclosed in an array. If the request was a form post and it was an upload the response will be sent back as a valid html document with the following content:

<html><body><textarea>{YOUR JSON RESPONSE HERE}</textarea></body></html> " must be back-slashed because the textarea will convert them to actual quotes. Therefore you must do a regular expression (/”/, ”\””)

I think that is an encoding issue there. The JSON should be without the HTML tags.

According to the http://www.sencha.com/products/extjs/extdirect specification

this is the reply that the sencha client expects from the server:

<html><body><textarea>{YOUR JSON RESPONSE HERE}</textarea></body></html>

I also tried replacing quotes with \" but that didn't seam to make a difference.

I guess what I really need is a sample of a good response xml/jspn text to model off of.

Thanks for the reply.

as I said ^^^

JSON looks like this:

Code:

{"foo":"bar","hello":"hi"}

<?
$conn = mysql_connect ("localhost", "root", "") or die (mysql_error ());
mysql_select_db ("extjs") or die (mysql_error ());
$q=mysql_query ("
INSERT INTO info (to, subject, msg) VALUES ('".$_POST['to']."','".$_POST['subject']."','".$_POST['msg']."')
") or die ('{"success":"false"}');
// json output to notify the insert is success or not
if ($q) {
echo '{"success":"true"}';
}
else {
echo '{"success":"false"}';
}
?>

I get the same error in my code shown above and i have no idea whats wrong, i can see that i did write the Json code correctly or didn't i?
