Question

这些是选择框中的选项。选择其中一个选项后，会出现一个文本框。

<select name="category" required id="category" style="width:75%;" onchange = "ShowHideDiv();">
   <option value="" disabled selected hidden>Category</option>
   <option value="Student">Student</option>
   <option value="Teacher">Teacher</option>
   <option value="Scientist">Scientist</option>
   <option value="Lab Manager">Lab Manager</option>
</select>

这些是根据选择框的选择而出现的文本框：

<div id="roll" style="display: none">
    <input name="roll" type="text" id="roll"/>
    <span class="highlight"></span>
    <span class="bar"></span>
    <label>Roll No</label>
</div>
<div id="teacher" style="display: none">
    <input name="des" type="text" id="teacher"/>
    <span class="highlight"></span>
    <span class="bar"></span>
    <label>Teacher's Designation</label>
</div>
<div id="scientist" style="display: none">
    <input name="des" type="text" id="scientist"/>
    <span class="highlight"></span>
    <span class="bar"></span>
    <label>Scientist's Designation</label>
</div>
<div id="manager" style="display: none">
    <input name="des" type="text" id="manager"/>
    <span class="highlight"></span>
    <span class="bar"></span>
    <label>Lab Manager's Designation</label>
</div>

这是用于在选择框中选择选项时显示文本框的脚本：

<script type="text/javascript">
function ShowHideDiv()
{
    var category = document.getElementById("category");
    var roll = document.getElementById("roll");
    var teacher = document.getElementById("teacher");
    var scientist = document.getElementById("scientist");
    var manager = document.getElementById("manager");
    roll.style.display = category.value == "Student" ? "block" : "none";
    teacher.style.display = category.value == "Teacher"? "block" : "none";
    scientist.style.display = category.value == "Scientist" ? "block" : "none";
    manager.style.display = category.value == "Lab Manager"? "block" : "none";
}

以下是在数据库中保存数据的代码：

<?php
include "connect.php";
if(isset($_POST["submit"]))
{
    $name=$_POST["name"];
    $gender=$_POST["gender"];
    $category=$_POST["category"];
    $roll=$_POST["roll"];
    $desig=$_POST["des"];
    $college=$_POST["college"];
    $department=$_POST["department"];
    $email=$_POST["email"];
    $phno=$_POST["phno"];
    $dob=$_POST["dob"];
    $lab=$_POST["lab"];

    $sql="insert into usercreation values('$name','$gender','$category','$roll','$desig','$college','$department','$email','$phno','$dob','$lab')";
    if(mysql_query($sql,$link))
    {
        header("location:usercreation.php?ok=1");

    }
    else
    {
        echo mysql_error(); 
    }
}
?>

我遇到了保存教师文本框和科学家文本框数据的问题。 roll和manager的数据保存在数据库和其他所有字段中。

问题已经解决了。感谢@Pablo Barria Urenda＆amp; @CaitLAN Jenner。

<div id="roll" style="display: none">
<input name="roll" type="text" id="roll"/>
<span class="highlight"></span>
<span class="bar"></span>
<label>Roll No</label>
</div>
<div id="teacher" style="display: none">
<input name="des1" type="text" id="teacher"/>
<span class="highlight"></span>
<span class="bar"></span>
<label>Teacher's Designation</label>
</div>
<div id="scientist" style="display: none">
<input name="des2" type="text" id="scientist"/>
<span class="highlight"></span>
<span class="bar"></span>
<label>Scientist's Designation</label>
</div>
<div id="manager" style="display: none">
<input name="des3" type="text" id="manager"/>
<span class="highlight"></span>
<span class="bar"></span>
<label>Lab Manager's Designation</label>
</div>

他建议的解决方案是更改文本框的名称。

以下是保存代码（已更改）

<?php
include "connect.php";
if(isset($_POST["submit"]))
{
    $name=$_POST["name"];
    $gender=$_POST["gender"];
    $category=$_POST["category"];
    $roll=$_POST["roll"];
    $des1=$_POST["des1"];
    $des2=$_POST["des2"];
    $des3=$_POST["des3"];
    $college=$_POST["college"];
    $department=$_POST["department"];
    $email=$_POST["email"];
    $phno=$_POST["phno"];
    $dob=$_POST["dob"];
    $lab=$_POST["lab"];

    $sql="insert into usercreation values('$name','$gender','$category','$roll','$des1','$des2','$des3','$college','$department','$email','$phno','$dob','$lab')";
    if(mysql_query($sql,$link))
    {
        header("location:usercreation.php?ok=1");

    }
    else
    {
        echo mysql_error(); 
    }
}
?>

无法将教师和科学家的值发布到数据库
