Read JSON response from Ext JS giving boolean false?! - El Forum - 08-12-2011

[eluser]CI_adis[/eluser]
Hi all,

I'm stuck with something... I tried to integrate Ext JS with CI and it works well. But when I submit something from Ext JS it returns a JSON object and I cannot read the content in my CI controller. The JSON is:

Code:
{
    "tasks": [
        {
            "taskId": "4",
            "taskCode": "777",
            "taskDescription": "Fix this",
            "taskDuration": "1",
            "reqCompletionDateTime": "2011-08-25T12:00:00",
            "customerId": "",
            "customerCode": "",
            "customerName": ""
        }
    ]
}

But when I want to read this in my controller:

Code:
var_dump($this->input->post());

It is giving me the error:

Quote:<pre class='xdebug-var-dump' dir='ltr'><small>boolean</small> <font color='#75507b'>false</font>
</pre>

The complete function in my controller:
Code:
function update_all_tasks()
     {
        var_dump($this->input->post());
     }

What can this be, I cannot find anything else that is weird??
If I create a test.html with one textfield and enter my json in that field I can read the response...

False means that Your POST request is empty. Try to check if You are actually getting any date by checking $_REQUEST variable, maybe result is a GET reqest? Smile

And in the request payload I see the JSON as mentioned in first post..
So my request is not empty, right??

I can read the JSON when I use this:

Code:
$result = NULL;
        if(function_exists('json_decode')) {
            $jsonData = json_decode(trim(file_get_contents('php://input')), true);
            $result = $jsonData['tasks'][0];
        }
        return $result;

sow this is not working:
Code:
var_dump($_POST);
or
Code:
var_dump($this->input->post());
and this is working:
Code:
file_get_contents('php://input')
is this a bug in 2.0.2??
