Question

我正在编写一个页面，当按下提交按钮时，它会运行一个sql脚本将表单添加到数据库中。但是，当按下提交按钮时，页面只会重新加载并且脚本不会运行。该页面的源代码如下所示

addResults.php：

<?php

if(isset($_POST['description'])){
    if(!isset($_POST['iscorrect']) || $_POST['iscorrect'] == ""){
        echo "Sorry, data is missing. Please press back and try again.";
        exit();
    }
    if(!isset($_POST['type']) || $_POST['type'] == ""){
        echo "Sorry, there was an error. Please press back and try again";
        exit();
    }
    require_once("scripts/connect_db.php");

    $team1 = $_POST['team1'];
    $team2 = $_POST['team2'];
    $score1 = $_POST['score1'];
    $score2 = $_POST['score2'];
    $year = $_POST['year'];
    $round = $_POST['round'];

    $type = $_POST['type'];
    $type = preg_replace('/[^a-z]/', "", $type);
    $team1 = strip_tags($team1);
    $team1 = mysql_real_escape_string($team1);
    $team2 = strip_tags($team2);
    $team2 = mysql_real_escape_string($team2);
    $score1 = strip_tags($score1);
    $score1 = mysql_real_escape_string($score1);
    $score2 = strip_tags($score2);
    $score2 = mysql_real_escape_string($score2);
    $year = strip_tags($year);
    $year = mysql_real_escape_string($year);
    $round = strip_tags($round);
    $round = mysql_real_escape_string($round);


    if($type == 'mr'){
    if((!$team1) || (!$team2) || (!$score1) || (!$score2) || (!$year) || (!$round)){
        echo "Sorry, All fields must be filled in. Press back and try again.";
        exit();
        }
    }
    if($type == 'mr'){
        $previousId = mysql_insert_id();
        mysql_query("UPDATE questions SET question_id='$previousId' WHERE id='$previousId' LIMIT 1")or die(mysql_error());
    }

    if($type == 'mr'){
    $sql2 = mysql_query("INSERT INTO questions (ID, Team1, Team2, Score1, Score2, Year, Round) VALUES ('$previousId', '$team1', '$team2', '$score1', '$score2', '$year', '$round')")or die(mysql_error());
    $message = 'Thank You, Your Result Has Been Added';
    header('location: addResults.php?msg='.$message.'');
    exit();
    }
$message = "";
if(isset($_GET['msg'])){
    $message = $_GET['msg'];
}

}
?>

Answer 1

由于@relentless和@MahasishShome已经注意到，您的更新在

之内

if(isset($_POST['description'])) {
// update ...
}

但您提交的表单中没有名为description的字段。

您必须插入名为description的（隐藏？）字段或测试另一个现有字段。

点击提交按钮时页面重新加载
