Question

//这是我的查询

if(isset($_POST["break-first"])) {
    $bflag='true';
    $bfid=$_POST["break-first"];

    $query = "SELECT * FROM food_details WHERE food_id = '$bfid'";
    $result = mysqli_query($_SESSION["connect"],$query);
        if(!$result) {
            $error = mysqli_error($_SESSION["connect"]);
            print $error;
            exit;
        }

    while ($row = mysqli_fetch_array($result)) {
        $bfid =$row["food_id"];
        $bf=$row["f_name"];
        $bprice= $row["price"];
    }

我收到此错误“列计数与第 1 行的值计数不匹配”

Answer 1

更改自

 $query = "SELECT * FROM food_details WHERE food_id = '$bfid'";

至

$query = "SELECT food_id,f_name,price FROM food_details WHERE food_id = '$bfid'";
