Question

在项目中工作，我有一个创建下拉菜单的按钮。菜单信息是从数据库生成的。当我尝试遍历所有内容以将选定的下拉值放入数据库时，什么也没发生。有什么想法吗？

PHP和HTML文件：等到单击“完成”按钮，然后遍历数据库以创建我想要插入数据库的值的数组。

<!DOCTYPE HTML>
<?php 
include 'tools.php';
session_start(); 
require_once "sessionVerify.php";
?>

<script language="javascript">
i=1;
function addCourse(){
    var table=document.getElementById("courseList");
    var clnNode=document.getElementById("courserow").cloneNode(true);
    var clnNode2=document.getElementById("questionRow").cloneNode(true);
    var clnNode3=document.getElementById("ratingSelects").cloneNode(true);  
    table.insertBefore(clnNode,table.lastChild);
    table.insertBefore(clnNode2,table.lastChild);
    table.insertBefore(clnNode3,table.lastChild);
}
</script>

用于打印表单的PHP函数：

function printStartingRows(){

    $result = queryDB("select * from EnrollmentInput where SurveyID=".$_SESSION['curSurvey'].";");
    $courseBuilder = queryDB("select IUID, FirstName from Student;");
    $courseList = array();
    while($cb = $courseBuilder->fetch_assoc()){
        $courseList[$cb['IUID']] = $cb['FirstName'];
    }

    while($row = $result->fetch_assoc()){
        print("<tr id='courserow'>");
        print("<td>");
        print("<h3>Student: </h3>");
        printCourseList($courseList[$row['CourseID']]);
        print("</td>");
        print("<td>");
        print("<h3>Student: </h3>");
    /*  printSemesterList($row['SemesterID']);
        print("</td>");
        print("</tr>");*/
        print("</tr>");

    }

    print("<tr id='courserow'>");

    print("<td>");
    print("<h3>Student: </h3>");
    printCourseList("");
        print("</td>");
    /*print("<td>");
    printSemesterList("");
    print("</td>");*/
    print("</tr>");

    print("<tr id='questionRow'>");
        print("<th>Motivation And General Attitude</th>");
    print("<th>Educational Initiative & Scholarship</th>");
    print("<th>Understanding of course material</th>");
    print("<th>Ability to apply course material</th>");
    print("<th>Oral English expression skills</th>");
    print("<th>Ability to analyze, integrate, and apply</th>");
    print("<th>Ethical standards & integrity</th>");
    print("<th>Respect for diversity</th>");
    print("</tr>");
    print("<tr id='ratingSelects'>");
    for ($xint=1; $xint<=8; $xint++){
    print('<td><select>     <option value="1">Poor</option>
        <option value="2">Less Than Acceptable</option>
        <option value="3">Satisfactory</option>
        <option value="4">Very Good</option>
    <option value="5">Excellent</option></select></td>');
    }
    print("</tr>");
    print("<br>");
}

最后，打印连接学生姓名的功能：

function printCourseList($s){//this is really print student

    $result = queryDB("SELECT concat (FirstName,' ', LastName) as StudentNames FROM `Student`");
    //$result = queryDB("SELECT *  FROM `Student`");
    // ^^ Unprofessional, fix later

    print('

        <input list="courses" name="enrolledCourses[]" value="'.$s.'">
        <datalist id="courses">');
    while($row = $result->fetch_assoc()){
        print('
            <option value="'.$row['StudentNames'].'"></option>
            ');
    }

    print('
        </datalist>
        ');
}

将下拉值添加到数据库？
