I have been trying to retrieve JSON data from my php file.Its giving me a hard time.This is my code
Code in my VIEW:
var productDetails = {'id':ISBNNumber,'qty':finalqty,'price':finalprice,'name':bookTitle}; var base_url = '<?php echo site_url() ?>'; $.ajax({ url: "<?php echo base_url() ?>index.php/user/Add_to_cart/addProductsToCart", type: 'POST', data:productDetails, dataType:'JSON', });
Trying to retrieve in my Controller:
echo $this->input->post("productDetails");
Outputs Nothing.
Here are my headers:
Remote Address:[::1]:80 Request URL:http://localhost/CI/index.php/user/Add_to_cart/addProductsToCart Request Method:POST Status Code:200 OK Request Headersview source Accept:application/json, text/javascript, */*; q=0.01 Accept-Encoding:gzip, deflate Accept-Language:en-US,en;q=0.8,fr;q=0.6 Connection:keep-alive Content-Length:52 Content-Type:application/x-www-form-urlencoded; charset=UTF-8 Cookie:ci_session=3E5SPro57IrJJkjs2feMNlmMrTqEXrTNN8UyEfleeothNnHwNxuCZDSx4a7cJZGjj7fyr2KLpj%2BPNJeGRSzSPVmcFHVEdhSk4D47ziOl4eZcTUAZlQrWa3EYIeQJVWxMpiGZS26MEfbSXNmfel9e8TcsJTreZHipvfisrJovbXEAW4Uv%2BwrJRep1KCi1MMaDCVJb9UEinRVcDtYe%2F86jhn7kOj4kraVmVzx%2FsOaO0rAxLyAUtez%2Feaa4zBwpN3Td153sAoIb3WxVHoEj2oKyH5prVHigbIhIBR6XZqjBkM6hjBuoD2OSZ2wgLbp9DEENMoqui4WYyHROBuS2DYiJajblcS0KiFga5k%2FQOODvE7p6n%2BozN5ciDliVjJ4PnJ5PD1GaPEmec5%2FbQSlOHYWZk%2F2Blzw3Nw0EtLL7wKDzzQY%3Df645c36bb3548eb8de915b73f8763d97a47783ce Host:localhost Origin:http://localhost Referer:http://localhost/CI/index.php/user/view_available_books/viewAvailableBooks/5 User-Agent:Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.111 Safari/537.36 X-Requested-With:XMLHttpRequest **Form Dataview** sourceview URL encoded id:234 qty:1 price:0.00 name:dasdadsd2q3e!@!@@
My Response which I can See in Developer tools:
Array ( [id] => 234 [qty] => 1 [price] => 0.00 [name] => dasdadsd2q3e!@!@@ )
But in browser, the output is nothing. I am trying to solve it for more than 4 hours now but in vain.
print_r($_POST); // outputs nothing echo $data = file_get_contents('php://input'); //outputs nothing echo $id = $this->input->post('productDetails');// outputs nothing
My View Code:
<script> $('#addtoCart').on('click',function(event){ event.preventDefault(); $(this).attr('disabled',"disabled"); finalprice = $.trim($('#price').val()); finalqty = $.trim($('#quantity').val()); var productDetails = JSON.stringify({'id':ISBNNumber,'qty':finalqty,'price':finalprice,'name':bookTitle}); var base_url = '<?php echo site_url() ?>'; // console.log($); $.ajax({ url: "<?php echo base_url() ?>index.php/user/Add_to_cart/addProductsToCart", type: 'POST', contentType: "application/json; charset=utf-8", data:productDetails, dataType:'html', }); }); </script>
Controller Code:
function addProductsToCart(){ var_dump(json_decode(file_get_contents("php://input"))); print_r($_POST); // $data = json_decode($_POST["productDetails"]); // var_dump($data); // echo $data = file_get_contents('php://input'); // print_r(json_decode($data)); // $id = $this->input->post('id'); // $qty = $this }

Answer
General method I use for my Ajax Calls in CI :
JS :
post_array = { "myvar" : "value1", "myvar2": "value2" } $.post(baseUrl + "/AjaxController/my_function", post_array, function(data) { var res = jQuery.parseJSON(data); alert(res.property); }
Controller :
public function my_function() { $myvar = $this->input->post('myvar'); $myvar2 = $this->input->post('myvar2'); //Stuff echo json_encode($myobject); }
