如何使用PHP PDO將具有多行的多個數組插入MySQL

Question

我正在嘗試使用PHP PDO將多個數組插入MySql數據庫。 它插入重復的行，而不是按我要求的方式插入。 下面是我的代碼

HTML

             <div class="col-md-4">
                    <div class="form-group">    
                        <label class="col-form-label"> Enter Product Name</label>
                        <input type="text" class="form-control" name="pname[]" placeholder="Product Name"/>
                    </div>
                </div> 

                <div class="col-md-4">
                    <div class="form-group">    
                        <label class="col-form-label"> No. of Pieces</label>
                        <input type="text" class="form-control" name="pcount[]" placeholder="No.Of Items"/>
                    </div>
                </div> 

                <div class="col-md-3">
                    <div class="form-group">    
                        <label class="col-form-label"> Estimated Amount</label>
                        <input type="text" class="form-control" name="estamount[]" placeholder="Estimated Amount of Each"/>
                    </div>
                    <p class="pull-left">Amount: &nbsp;<div class="Amount"></div></p>
                </div>

和PHP代碼是

$totalamount=0;
        foreach($_POST['pname'] as $proname){

            foreach($_POST['pcount'] as $quantity){

                foreach($_POST['estamount'] as $estamount){

                    $totalamount = $quantity*$estamount;

                    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
                    $sql = "INSERT INTO `order`(custname, contact, product_name, quantity, est_amount, advance_paid, delivery_period, date, status, total_amount, orderid) VALUES(:custname, :contact, :product_name, :quantity, :est_amount, :advance_paid, :delivery_period, :date, :status, :total_amount, :orderid)";
                    $query=$dbh->prepare($sql);
                    $query->bindParam(':custname',$custmorname,PDO::PARAM_STR);
                    $query->bindParam(':contact',$contact,PDO::PARAM_STR);
                    $query->bindParam(':product_name',$proname,PDO::PARAM_STR);
                    $query->bindParam(':quantity',$quantity,PDO::PARAM_STR);
                    $query->bindParam(':est_amount',$estamount,PDO::PARAM_STR);
                    $query->bindParam(':advance_paid',$advancepaid,PDO::PARAM_STR);
                    $query->bindParam(':delivery_period',$delevery,PDO::PARAM_STR);
                    $query->bindParam(':date',$date,PDO::PARAM_STR);
                    $query->bindParam(':status',$status,PDO::PARAM_STR);
                    $query->bindParam(':orderid',$orderid,PDO::PARAM_STR);
                    $query->bindParam(':total_amount',$totalamount,PDO::PARAM_STR);
                    $query->execute();
                    }
              }
        }

我想在一條記錄中插入$proname , $quantity , $est_amount ，並且應該根據插入的值插入多個重新編碼

由於您有嵌套的for循環，因此肯定會導致重復記錄。 讓我快速糾正。

$totalamount=0;
for ($i = 0; $i < count($_POST['pname']); $i++){
    $proname = $_POST['pname'][$i];
    $quantity = $_POST['pcount'][$i];
    $estamount = $_POST['estamount'][$i];
    $totalamount = $quantity*$estamount;

    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $sql = "INSERT INTO `order`(custname, contact, product_name, quantity, est_amount, advance_paid, delivery_period, date, status, total_amount, orderid) VALUES(:custname, :contact, :product_name, :quantity, :est_amount, :advance_paid, :delivery_period, :date, :status, :total_amount, :orderid)";
    $query=$dbh->prepare($sql);
    $query->bindParam(':custname',$custmorname,PDO::PARAM_STR);
    $query->bindParam(':contact',$contact,PDO::PARAM_STR);
    $query->bindParam(':product_name',$proname,PDO::PARAM_STR);
    $query->bindParam(':quantity',$quantity,PDO::PARAM_STR);
    $query->bindParam(':est_amount',$estamount,PDO::PARAM_STR);
    $query->bindParam(':advance_paid',$advancepaid,PDO::PARAM_STR);
    $query->bindParam(':delivery_period',$delevery,PDO::PARAM_STR);
    $query->bindParam(':date',$date,PDO::PARAM_STR);
    $query->bindParam(':status',$status,PDO::PARAM_STR);
    $query->bindParam(':orderid',$orderid,PDO::PARAM_STR);
    $query->bindParam(':total_amount',$totalamount,PDO::PARAM_STR);
    $query->execute();
