<button  id='btn' name='btn' class="btnn primary-btn" type='submit'>Submit</button>

我总共有10行这样的

PHP

if(isset($_POST['btn'])){
    ob_start();
    $order_id = $_POST["order_id"];
    $desc = $_POST["desc"];
    $quant = $_POST["quant"];
    $unit_price = $_POST["unit_price"];
    $total = $_POST["total"];

    $query = mysqli_query($con,"insert into orders (id,description,quantity,unit_price,total) values('".$order_id."','".$desc."','".$quant."','".$unit_price."','".$total."') ");

我正在尝试在一个查询中插入数据库中的所有记录？我如何在一个查询中插入数据库中的所有行？

Answer 1

如果要使用循环来执行

if(isset($_POST['btn'])){
    ob_start();
    foreach($_POST["order_id"] as $key =>$value){
        $order_id = $value;
        $desc = $_POST["desc"][$key];
        $quant = $_POST["quant"][$key];
        $unit_price = $_POST["unit_price"][$key];
        $total = $_POST["total"][$key];

        $query = mysqli_query($con,"insert into orders (id,description,quantity,unit_price,total) values('".$order_id."','".$desc."','".$quant."','".$unit_price."','".$total."') ");

    }


}

否则，您可以使用多个插入查询

INSERT INTO example
      (example_id, name, value, other_value)
    VALUES
      (100, 'Name 1', 'Value 1', 'Other 1'),
      (101, 'Name 2', 'Value 2', 'Other 2'),
      (102, 'Name 3', 'Value 3', 'Other 3'),
      (103, 'Name 4', 'Value 4', 'Other 4');
