Question

我是php的新手。我选择多项测验，从MySQL数据库中检索问题并将其显示给用户，并将所选的选择保存到数据库中，我想要做的就是添加用户到达问题10时测验的进度条。进度条更改为20％，依此类推..。我使用问题ID来检索我在网上搜索的问题，但找不到有用的资源我正在尝试做.. 将提供任何帮助

这是 exam.php

   <body>

<?Php
require "config0.php";
$count=$dbo->prepare("select * from questions where question_id=1 ");
if($count->execute()){
$row = $count->fetch(PDO::FETCH_OBJ);
}
echo "

        <table>
        <tr><th>
        <input type='' id=question_id value=$row->question_id>
        </th></tr>
        <tr><th>
        <h4 id='q1'>$row->question</h4>
        </th></tr>

        <tr><td>

这是从数据库收集数据

的脚本

<?Php
session_start();
error_reporting(E_ALL); 
ini_set('display_errors', 1);
require "config0.php";




$question_id=$_POST['question_id'];


$option_no=$_POST['option_no']; // User choice

//////// Collected from databse ///////
$question_id=$question_id+1;



$no_questions = $dbo->query("select count(question) from questions
left join servey_question on questions.question_id = servey_question.question_id where servey_id = 'serv01' ")->fetchColumn();

if($question_id > $no_questions) {
    $next='F'; // Flag is set to display thank you message
    echo json_encode(array("next"=>$next));
} else {
    $next='T'; // Flag is set to display next question
    $count=$dbo->prepare("select * from questions where question_id=$question_id");
    $count->execute();
    $row = $count->fetch(PDO::FETCH_OBJ);
    $main= array("data"=>array(
        "q1"=>"$row->question",
        "opt1"=>"$row->opt1",
        "opt2"=>"$row->opt2",
        "opt3"=>"$row->opt3",
        "opt4"=>"$row->opt4",
        "opt5"=>"$row->opt5",
        "opt6"=>"$row->opt6",
        "question_id"=>"$question_id",
        "category_id"=>"$row->category_id"
    ),
    "next"=>"$next");
    echo json_encode($main);
}
