Question

我正在查询中将答案插入答案表中，我需要设置正确的答案等于1，并且错误的答案等于0，因为我使用单选按钮将值分配到回答，但每次当我运行查询时，即使我点击了不同的单选按钮，第一个答案总是得到值1

   <?php 


require_once("scripts/connect_db.php");
if(isset($_POST['submit'])){

$question = $_POST['desc'];
$is_correct = $_POST['iscorrect'];

$answers = array($_POST['answer1'],$_POST['answer2']);
var_dump($is_correct);
var_dump($answers);
var_dump($_POST);

    $sql = mysqli_query($con,"INSERT INTO questions (question) VALUES ('".$question."')") or die(mysqli_error($con));
    $lastId = mysqli_insert_id($con);
    mysqli_query($con,"UPDATE questions SET question_id='".$lastId."' WHERE id='".$lastId."' LIMIT 1") or die(mysqli_error($con));  


    if($sql){

        foreach($answers as $answer => $value){

                if($value != ""){

                    if($is_correct == "iscorrect" ){
                        $is_correct = 1 ;

                    }else {

                        $is_correct = 0 ;
                    }
                    $query = mysqli_query($con,"INSERT INTO answers (question_id, answer, correct) VALUES ('".$lastId."', '".$value."', '".$is_correct."')") or die(mysqli_error($con));

                    if($query ){
                        continue;
                    }else{
                        dir("Error".mysqli_error($con));
                    }

                }



        }// Foreach
    }





    }// End of submit

?>

Answer 1

试试这个

if($sql){

    foreach($answers as $answer => $value){

            if($value != ""){

                if($is_correct == "iscorrect" ){
                    $is_correct = "1" ;

                }else {

                    $is_correct = "0" ;
                }
                $query = mysqli_query($con,"INSERT INTO answers (question_id, answer, correct) VALUES ('$lastId', '$value', '$is_correct')") or die(mysqli_error($con));

                if($query ){
                    continue;
                }else{
                    dir("Error".mysqli_error($con));
                }

            }
    }
}

Answer 2

我做了一些mods，看看这有帮助..

<?php
require_once("scripts/connect_db.php");
if(isset($_POST['submit'])){

$question = $_POST['desc'];
$is_correct = $_POST['iscorrect'];

$answer1 = $_POST['answer1']
$answer2 = $_POST['answer2']);
var_dump($is_correct);
var_dump($answers);
var_dump($_POST);

$sql = mysqli_query($con,"INSERT INTO questions (question) VALUES ('".$question."')") or die(mysqli_error($con));
$lastId = mysqli_insert_id($con);
mysqli_query($con,"UPDATE questions SET question_id='".$lastId."' WHERE id='".$lastId."' LIMIT 1") or die(mysqli_error($con));  

                $is_correct = 1 ;
                $is_wrong = 0;
                if($is_correct == "iscorrect1" ){
                $query = mysqli_query($con,"INSERT INTO answers (question_id, answer, correct) VALUES ('".$lastId."', '".$answer1."', '".$is_correct."'),('".$lastId."', '".$answer2."', '".$is_wrong."')") or die(mysqli_error($con));
                }
                else {
                $query = mysqli_query($con,"INSERT INTO answers (question_id, answer, correct) VALUES ('".$lastId."', '".$answer1."', '".$is_wrong."'),('".$lastId."', '".$answer2."', '".$is_correct."')") or die(mysqli_error($con));
                }
                if($query ){
                    continue;
                }else{
                    dir("Error".mysqli_error($con));
                }


}
