我一直在尝试从我的PHP文件中检索
JSON数据.它让我很难.这是我的代码
我的视图中的代码：
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',});
试图在我的控制器中检索：
echo $this->input->post("productDetails");
输出什么都没有.
这是我的标题：
Remote Address:[::1]:80 Request URL:http://localhost/CI/index.PHP/user/Add_to_cart/addProductsToCart Request Method:POST Status Code:200 OK Request Headersview source Accept:application/json,text/javascript,*/*; q=0.01 Accept-Encoding:gzip,deflate Accept-Language:en-US,en;q=0.8,fr;q=0.6 Connection:keep-alive Content-Length:52 Content-Type:application/x-www-form-urlencoded; charset=UTF-8 Cookie:ci_session=3E5SPro57IrJJkjs2feMNlmMrTqEXrTNN8UyEfleeothNnHwNxuCZDSx4a7cJZGjj7fyr2KLpj%2BPNJeGRSzSPVmcFHVEdhSk4D47ziOl4eZcTUAZlQrWa3EYIeQJVWxMpiGZS26MEfbSXNmfel9e8TcsJTreZHipvfisrJovbXEAW4Uv%2BwrJRep1KCi1MMaDCVJb9UEinRVcDtYe%2F86jhn7kOj4kraVmVzx%2FsOaO0rAxLyAUtez%2Feaa4zBwpN3Td153sAoIb3WxVHoEj2oKyH5prVHigbIhIBR6XZqjBkM6hjBuoD2OSZ2wgLbp9DEENMoqui4WYyHROBuS2DYiJajblcS0KiFga5k%2FQOODvE7p6n%2BozN5ciDliVjJ4PnJ5PD1GaPEmec5%2FbQSlOHYWZk%2F2Blzw3Nw0EtLL7wKDzzQY%3Df645c36bb3548eb8de915b73f8763d97a47783ce Host:localhost Origin:http://localhost Referer:http://localhost/CI/index.PHP/user/view_available_books/viewAvailableBooks/5 User-Agent:Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/40.0.2214.111 Safari/537.36 X-Requested-With:XMLHttpRequest **Form Dataview** sourceview URL encoded id:234 qty:1 price:0.00 name:dasdadsd2q3e!@!@@
我在Developer工具中可以看到的响应：
Array
(
[id] => 234
[qty] => 1
[price] => 0.00
[name] => dasdadsd2q3e!@!@@
)
但在浏览器中,输出什么都没有.我现在试图解决它超过4个小时但是徒劳无功.
print_r($_POST); // outputs nothing
echo $data = file_get_contents('PHP://input'); //outputs nothing
echo $id = $this->input->post('productDetails');// outputs nothing
我的观点代码：
<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,'name':bookTitle});
var base_url = '<?PHP echo site_url() ?>';
// console.log($);
$.ajax({
url: "<?PHP echo base_url() ?>index.PHP/user/Add_to_cart/addProductsToCart",contentType: "application/json; charset=utf-8",dataType:'html',});
});
</script>
控制器代码：
function addProductsToCart(){
var_dump(json_decode(file_get_contents("PHP://input")));
print_r($_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
}
我用于CI中的Ajax调用的一般方法：
JS：
post_array =
{
"myvar" : "value1","myvar2": "value2"
}
$.post(baseUrl + "/AjaxController/my_function",post_array,function(data)
{
var res = jQuery.parseJSON(data);
alert(res.property);
}
控制器：
public function my_function()
{
$myvar = $this->input->post('myvar');
$myvar2 = $this->input->post('myvar2');
//Stuff
echo json_encode($myobject);
}
