【中文标题】成功提交表单，但控制台出现一个错误，例如发生数据库错误错误号：1048 - Codeigniter

【英文标题】：Successfully submitted form but one error in console, like A Database Error Occurred Error Number: 1048 - Codeigniter

【发布时间】：2020-02-19 00:41:30

【问题描述】：

当我成功提交表单并在表格中插入所有数据时，并且在控制台中出现如下错误，代码有问题吗？，我发现错误中的日期异常，日期显示为 '1970- 01-01'。但是我选择了今天的日期，但错误地只显示了“1970-01-01”；

A Database Error Occurred
Error Number: 1048

Column 'purchase_shopId' cannot be null

INSERT INTO `stock_purchase_history` (`purchase_shopId`, `purchase_productID`, `purchase_quantity`, `purchase_costPrice`, `purchase_TotalRate`, `purchase_tax`, `purchase_taxEmp`, `purchase_sellingPrice`, `purchase_employeeSellingPrice`, `purchase_supplierName`, `purchase_invoice`, `purchase_PurchaseDate`) VALUES (NULL, NULL, NULL, NULL, 0, NULL, NULL, 0, 0, NULL, NULL, '1970-01-01')

Filename: C:/xampp/htdocs/stock/system/database/DB_driver.php

Line Number: 691

我的查询代码

public function insertPurchaseData()
    
         $shopId =  $this->input->post('shopId');
         $productID =  $this->input->post('productID');
         $quantity =  $this->input->post('quantity');
         $costPrice =  $this->input->post('costPrice');         
         $PurchaseTotalRate = $quantity*$costPrice;
         $taxNormal =  $this->input->post('taxNormal'); 
         $taxEmp =  $this->input->post('taxEmp');
         $supplierName =  $this->input->post('supplierName');
         $invoice =  $this->input->post('invoice');
         $PurchaseDate =  date('Y-m-d', strtotime($this->input->post('PurchaseDate')));        
         //  normal Selling price
         $sellingPrice=($costPrice*$taxNormal)/100+$costPrice ;

         //  emp selling price
         $employeeSellingPrice=($costPrice*$taxEmp)/100+$costPrice;

        $purchaseData =array(

            'purchase_shopId'               => $shopId,                  
            'purchase_productID'            => $productID, 
            'purchase_quantity'             =>$quantity,
            'purchase_costPrice'            =>$costPrice,
            'purchase_TotalRate'            =>$PurchaseTotalRate,
            'purchase_tax'                  =>$taxNormal,
            'purchase_taxEmp'                  =>$taxEmp,
            'purchase_sellingPrice'         =>$sellingPrice,
            'purchase_employeeSellingPrice'=>$employeeSellingPrice,
            'purchase_supplierName'         =>$supplierName,
            'purchase_invoice'               =>$invoice,
            'purchase_PurchaseDate'         =>$PurchaseDate

            );
            $this->db->insert('stock_purchase_history',$purchaseData);



    

看下面的ajax代码

      if(result == '1234567')
    
            $.ajax(
            type: "POST",
            url: "<?php echo site_url('Con_purchase/add_purchase_for_shop')?>",
            dataType: "JSON",
            data:  
                    shopId: shopId,
                    productID: productID,
                    quantity: quantity,
                    costPrice : costPrice ,
                    taxNormal : taxNormal ,
                    taxEmp : taxEmp ,                       
                    supplierName : supplierName, 
                    invoice  : invoice , 
                    PurchaseDate   : PurchaseDate  
            ,
            success: function(data) 
                          if (data == '1') 
                            var btn = $(this).closest("tr")
                            var name = inputData.find("button").prop('disabled', false).css(
                            "background-color", "green"); 
                     else 
                            var btn = $(this).closest("tr")
                            var name = inputData.find("button").prop('disabled', true).css(
                            "background-color", "#2d7bf4");

                    
            

        );
        return false;

【问题讨论】：

var_dump 您的 post 数组并检查您的数据是否正确传递给控制器​​。 var_dump($this->input->post());

【参考方案1】：

您必须将列结构更改为 null 'purchase_shopId'，因为您已选中了 null 复选框。

【参考方案2】：

“purchase_shopId”列不能为空，您可以在数据库中更改“purchase_shopId”可以为空。

ALTER TABLE `MyTable`
ALTER COLUMN `purchase_shopId` varchar(20) 
DEFAULT NULL
