我想保存具有多行的表，当我尝试保存数据时，动态生成的第一个字母保存在数据库中。当我尝试保存下一行时，它在控制台中显示500错误。我想在数据库中逐个保存所有行的所有数据我该如何实现？
这是我的代码：
<!-- <form action="" method="POST"> -->
<?php $data = array(
'id'=>'inventory_form',
); ?>
<?php echo form_open('main/store',$data); ?>
<div class="table-responsive">
<table class="table table-bordered table-hover" id="inv_tbl">
<thead>
<th>No</th>
<th>~</th>
<th>Barcode</th>
<th>Product Name</th>
<th>SM</th>
<th>SPL</th>
<th>Quantity</th>
<th>Price</th>
<th>Discount</th>
<th>Amount</th>
<th><input type="button" value="+" id="add" class="btn btn-primary add_inv_row"></th>
</thead>
<tbody class="detail">
<tr>
<td class="no">1</td>
<td class="text-center"><input type="checkbox" id="till_check" class="is_checked" name="till_check[]" value="Bike"></td>
<td>
<select name="barcode[]" id="barcode" class="form-control selectpicker barcode" data-live-search="true">
<option value="">Please select a barcode</option>
<?php foreach($barcodes as $barcode) :?>
<option value="<?php echo $barcode->barcode; ?>"><?php echo $barcode->barcode; ?></option>
<?php endforeach; ?>
</select>
</td>
<td><input type="text" id="brcode_product" class="form-control productname" name="productname[]"></td>
<td>
<select name="sm[]" id="sm" class="form-control selectpicker sm" data-live-search="true">

<?php foreach($employee_codes as $employee_code) :?>
<option value="<?php echo $employee_code->emp_code; ?>"><?php echo $employee_code->emp_code; ?></option>
<?php endforeach; ?>
</select>
</td>

<td><input type="text" id="discount" class="form-control discount" name="discount[]"></td>

<td><a href="#" class="remove">Delete</a></td>
</tr>

<?php echo form_close(); ?>

我的Javascript代码： -
function total() {
var t = 0;
$('.amount').each(function (i, e) {
var amt = $(this).val() - 0;
t += amt;
});
$('.total').html(t);
}
function addnewrow() {
var n = ($('.detail tr').length - 0) + 1;
var tr = '<tr>' +
'<td class="no">' + n + '</td>' +
'<td><input type="checkbox" class="till_check" name="till_check[' + till_check_counter + ']" id="till_check[' + till_check_counter + ']"></td>' +
'<td><select class="form-control barcode selectpicker dyselect_' + product_barcode_counter + '" data-live-search="true" name="barcode[' + product_barcode_counter + ']" id="barcode[' + product_barcode_counter + ']">' + '<option>Please select a bar code</option>' + '</select></td>' +

'<td><a href="#" class="remove">Delete</td>' +
'</tr>';
$('.detail').append(tr);
//increamenting the counter

$('#save_btn').on('click', function () {

var productname = $('#brcode_product').val();

var spl = $('#spl').val();
var quantity = $('#quantity').val();
var price = $('#price').val();
var discount = $('#discount').val();
var amount = $('#amount').val();
var dataString = 'barcode=' + barcode + '&productname=' + productname + '&sm=' + sm + '&spl=' + spl + '&quantity' + quantity + '&price=' + price + '&discount=' + discount + '&amount=' + amount;
$.ajax({
url: "http://localhost/retail/main/store",
type: "POST",
data: {
/*barcode: barcode,

spl: spl,
quantity: quantity,
price: price,

data:$('#inventory_form').serialize()
},
success: function (res) {
alert(res);
}
});
这是我的Conroller代码：
public function store(){
/* echo ($_POST['barcode']);
echo "<br/>";
echo ($_POST['productname']);
echo "<br/>";
echo ($_POST['smsm']);
echo "<br/>";
echo ($_POST['spl']);
echo "<br/>";
echo ($_POST['quantity']);
echo "<br/>";
echo ($_POST['price']);
echo "<br/>";
echo ($_POST['discount']);
echo "<br/>";
echo ($_POST['amount']);
echo "<br/>";*/
//echo $this->input->post('barcode');
if ($this->session->userdata('status')== 1) {
for ($i = 0; $i < count($_POST['productname']); $i++) {
$order_id = $this->session->userdata('id');
$product_name = $this->input->post('productname')[$i];
$barcode = $this->input->post('barcode')[$i];
$spl= $this->input->post('spl')[$i];
$sm= $this->input->post('sm')[$i];
$quantity = $this->input->post('quantity')[$i];
$price = $this->input->post('price')[$i];
$discount =$this->input->post('discount')[$i];
$amount = $this->input->post('amount')[$i];
$data = array(
'order_id'=> $order_id,
'product_name'=>$product_name,
'barcode'=> $barcode,
'sm'=> $sm,
'spl'=> $spl,
'quantity'=>$quantity,
'price'=>$price,
'discount'=> $discount,
'amount'=> $amount,
);
$this->Sale_model->insert_sales_data($data);
echo "Data inserted successfully!";
}
}
else
{
redirect('login');
}
}
我正在使用Codeigniter。请告诉我，我上面提到的功能如何？
答案 0 :(得分：0)
为什么在ajax请求中获得单个值？
var barcode = $('#barcode option:selected').val();
var productname = $('#brcode_product').val();
var sm = $('#sm option:selected').val();
var spl = $('#spl').val();
var quantity = $('#quantity').val();
var price = $('#price').val();
var discount = $('#discount').val();
var amount = $('#amount').val();
为什么不只是序列化您的表单然后传递序列化数据？
答案 1 :(得分：0)
$('#save_btn').on('click', function () { var formdataString = $("#inventory_form"); $.ajax({ url: "http://localhost/retail/main/store", type: "POST", data: formdataString.serialize(), success: function (res) { alert(res); } }); });
