我有一点错误，我无法分辨出错误的来源。
我正在构建一个购物车系统，该系统将在提交时从购物车中将多个数据插入数据库。
我正在使用AJAX而且我有错误，请我帮忙。
以下是我的代码段：
JavaScript代码
function addSale(payment_type, cash_tendered) {
var cust_name = $("#cust_name").val();
var amt_owed = $("#amt_owed").val();
$.confirm({
title: 'Checkout',
content: '' +
'<form action="" class="formName" role="form">' +
'<div class="form-group">' +
'<label>Payment Type</label>' +
'<select id="eType" class="name form-control">' +
'<option value="cash">Cash</option>' +
'<option value="card">Card</option>' +
'</select>' +
'</div>' +
'<div class="form-group">' +
'<label>Cash Tendered</label>' +
'<input type="number" id="eCash" placeholder="Cash Tendered" class="name form-control">' +
'</div>' +
'</form>',
buttons: {
cancel: function () {
//close
},
formSubmit: {
text: 'Checkout',
btnClass: 'btn-success',
action: function () {
payment_type = this.$content.find('#eType').val();
cash_tendered = this.$content.find('#eCash').val();
if (!payment_type || !cash_tendered) {
$.alert('Please fill all fields.');
return false;
}
$.confirm({
title: 'Do you want to continue?',
type: 'orange',
content: 'Click Ok to add sale',
buttons: {
cancel: function () {
},
proceed: {
text: 'Ok',
btnClass: 'btn btn-success',
action: function () {
var addUrl = "home/addsales";
addUrl += "/" + payment_type;
addUrl += "/" + cash_tendered;
addUrl += "/" + cust_name;
addUrl += "/" + amt_owed;
//
$.ajax({type: 'GET', url: addUrl, data: {},
success: function (result) {
$.alert({
content: result
});
$("#eType").val("");
$("#eCash").val("");
$("#cust_name").val("");
$("#amt_owed").val("");
location.reload();
},
error: function (xhr, status, error) {
$.alert({
content: 'Could not complete the process. ' + error
});
}
});
}
}
}
});
}
}
},
onContentReady: function () {
// bind to events
var jc = this;
this.$content.find('form').on('submit', function (e) {
// if the user submits the form by pressing enter in the field.
e.preventDefault();
jc.$$formSubmit.trigger('click'); // reference the button and click it
});
}
});
}
以下是家庭控制器代码：
private function addsales($payment_type = null, $cash_tendered = null, $cust_name = null, $amt_owed = null) {
if (isset($payment_type, $cash_tendered)) {
$email = $_SESSION[DbStrings::$EMAIL];
$payment_type = $this->test_input($payment_type);
$cash_tendered = $this->test_input($cash_tendered);
$insertedSale = $this->member->insertDailySale($email, $payment_type, $cash_tendered);
$cust_name = $this->test_input($cust_name);
$amt_owed = $this->test_input($amt_owed);
$insertedCredit = 1;
if (isset($cust_name, $amt_owed) && $amt_owed > 0) {
$insertedCredit = $this->member->insertCredit($email, $cust_name, $amt_owed);
}
if ($insertedSale && $insertedCredit) {
$_SESSION['temp_invoice'] = $_SESSION[DbStrings::$INVOICE];
$chars = "003232303232023232023456789";
srand((double) microtime() * 1000000);
$i = 0;
$pass = '';
while ($i <= 7) {
$num = rand() % 33;
$tmp = substr($chars, $num, 1);
$pass = $pass . $tmp;
$i++;
}
$alpha = 'NM-' . $pass;
$_SESSION[DbStrings::$INVOICE] = $alpha;
echo "Your sale has been inserted succesfully";
} else {
echo "There was a problem inserting your sale. Please try again.";
}
} else {
echo 'Please fill all fields';
}
}
以下是我的模型代码，它仍然提取其他功能：
public function insertDailySale($email, $payment_type, $cash_tendered) {
$invoice = $_SESSION[DbStrings::$INVOICE];
$this->db->from(DbStrings::$SALES_ORDER_TABLE_NAME);
$condition = array(DbStrings::$EMAIL => $email, DbStrings::$INVOICE => $invoice);
$this->db->where($condition);
$query = $this->db->get();
$checks = $query->result_array();
foreach ($checks as $queries) {
$productID = $queries[DbStrings::$PRODUCTID];
$quantity = $queries[DbStrings::$SALES_QUANTITY];
$amount = $queries[DbStrings::$SALES_AMOUNT];
$profit = $queries[DbStrings::$SALES_PROFIT];
$product_code = $queries[DbStrings::$PRODUCT_CODE];
$product_name = $queries[DbStrings::$PRODUCT_NAME];
$product_selling = $queries[DbStrings::$PRODUCT_SELLING];
$this->deductInventory($email, $product_code, $quantity);
$this->updateQuantitySold($email, $product_code, $quantity);
$cost_price = $this->product->getCostPrice($product_code);
$data[] = array(
DbStrings::$EMAIL => $email,
DbStrings::$INVOICE => $invoice,
DbStrings::$PRODUCTID => $productID,
DbStrings::$SALES_QUANTITY => $quantity,
DbStrings::$SALES_AMOUNT => $amount,
DbStrings::$SALES_PROFIT => $profit,
DbStrings::$PRODUCT_CODE => $product_code,
DbStrings::$PRODUCT_NAME => $product_name,
DbStrings::$PRODUCT_CP => $cost_price,
DbStrings::$PRODUCT_SP => $product_selling,
DbStrings::$PAYMENT_TYPE => $payment_type,
DbStrings::$CASH_TENDERED => $cash_tendered,
DbStrings::$DATE_CREATED => time()
);
$inserted = $this->db->insert_batch(DbStrings::$DAILYSALES_TABLE_NAME, $data);
}
return $inserted;
}
通过上述内容，我得到了这个错误的标记：
插入促销时出现问题。请再试一次。
我需要帮助。
答案 0 :(得分：0)
错误来自我的数据库结构。作为internal server error，它来自数据库。
我意识到我从数据库表中删除了一个列，并且我仍在将数据发送到已删除的列。
感谢各位帮忙的尝试。
