我试图将存储在Javascript数组中的一些数据传递给服务器进行数据库处理。我使用的是codeignier。
Javascript数组(unitdata_set): -
[{"unit_id":"13","unit_title":"Testsdsdf","unit_max_occupancy":"3","unit_no":"1","unit_no_adults":"1","unit_no_children":"1","unit_no_extrabed":0,"unit_mealtype":"Full Board","unit_fullboard_adult":"6000.00","unit_fullboard_child":"4000.00","unit_halfboard_adult":"1800.00","unit_halfboard_child":"1200.00","room_total":"81600.00","all_room_price":"81600.00","extra_bed_price":"4.00","meal_price":22000,"saving_amount":16320,"discounted_bedroom_price":65280},{"unit_id":"14","unit_title":"Res2","unit_max_occupancy":"12","unit_no":"0","unit_no_adults":"0","unit_no_children":"0","unit_no_extrabed":0,"unit_mealtype":"Bed and Breakfast","unit_fullboard_adult":"9000.00","unit_fullboard_child":"7000.00","unit_halfboard_adult":"7000.00","unit_halfboard_child":"5000.00","room_total":"86400.00","all_room_price":"0.00","extra_bed_price":"","meal_price":0,"saving_amount":0,"discounted_bedroom_price":0}]
Ajax功能: -
function sendBooking(){
var boooking_url = "<?php echo site_url('tempbooking/addBooking'); ?>";
var data_booking = '';
data_booking = JSON.stringify(unitdata_set);
$.post(boooking_url,{
'booking_data[]':data_booking
},function(data){
console.log(data);
});
}
我的控制器功能,用于接收json数据: -
function addBooking(){
$booking_data=$this->input->post('booking_data');
foreach ($booking_data as $booking) {
$booking_attr = json_decode($booking);
echo $booking_attr->unit_id . " " . $booking_attr->unit_title;
//echo $booking_attr['unit_id'] . " " . $booking_attr['unit_title'];
}
}
我收到的错误消息: -
<h4>A PHP Error was encountered</h4>
<p>Severity: Notice</p>
<p>Message: Trying to get property of non-object</p>
<p>Filename: controllers/tempbooking.php</p>
<p>Line Number: 156</p>
</div><div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

也许是因为您的JSON对象在数组中?
[ {JSON} ]
尝试修改您的php函数,以便访问数组中的JSON:
function addBooking(){
$booking_data=$this->input->post('booking_data');
foreach ($booking_data as $booking) {
//NEW:
$booking_attr = json_decode($booking[0]);
echo $booking_attr->unit_id . " " . $booking_attr->unit_title;
}
}

尝试更改您的控制器
function addBooking()
{
$booking_data=json_decode($this->input->post('booking_data'));
foreach ($booking_data as $booking)
{
$booking_attr = ($booking);
echo $booking_attr->unit_id . " " . $booking_attr->unit_title;
//echo $booking_attr['unit_id'] . " " . $booking_attr['unit_title'];
}
}
并改变你的javascript代码
function sendBooking()
{
var boooking_url = "<?php echo site_url('tempbooking/addBooking'); ?>";
var data_booking = '';
data_booking = (unitdata_set);
$.post(boooking_url,{
'booking_data':data_booking
},function(data){
console.log(data);
});
}

由于某种原因,json_decode不解码包含对象的数组。如果您使用javascript数组将其传递给服务器端/ php,请先将数组添加到对象中。按照以下步骤完成此操作。
请将您的数组添加到对象中。如下: -
var unitdata_set = [];
var obj_userbooking_data = {"bookings":unitdata_set}; //Added the above array into a new object and passed it to the server
确保JSON.stringify对象。
data_booking = JSON.stringify(obj_userbooking_data);
因此功能变为
function sendBooking(){
var boooking_url = "<?php echo site_url('booking/addBooking'); ?>";
var data_booking = '';
data_booking = JSON.stringify(obj_userbooking_data);
$.post(boooking_url,{
'booking_data':data_booking
},function(data){
console.log(data);
});
}
使用json_decode解码转换为JSON字符串的对象,在客户端使用JSON.stringify。因此,您的服务器端/ php / Codeigniter控制器功能变为: -
function addBooking(){
$booking_data=$this->input->post('booking_data');
$booking_data=json_decode($booking_data,true);
echo 'Your Data: ' . $booking_data[0]['unit_id'];
}
