我有一个表单，我有 JS 表单验证。但验证过程不起作用。插入过程工作正常。
以下是将数据插入mysql数据库的表格-
<?php
session_start();
include("includes/connection.php");
include("header.php");
include("includes/adminmenu.php");
if(isset($_SESSION['username']))
{
//echo $_SESSION['username'];
?>
<!--Javasript Validation File Import -->
<script type="text/javascript" src="js/qcheck.js"></script>
<script type="text/javascript" language="JavaScript">
function HidePart(d) { document.getElementById(d).style.display = "none"; }
function ShowPart(d) { document.getElementById(d).style.display = "block"; }
function CheckboxChecked(b,d)
{
if(b) { ShowPart(d); }
else { HidePart(d); }
}
</script>
<br />
<div class="userstat">
<div style="background-color:#666666; text-align:center; font-weight:bold; color:#FFFFFF; font-size:24px;"><span>Insert A new Question</span></div>
<br />
<div class="statdata">
<form action="includes/insertq.php" method="POST" name="qform" onSubmit="return valide()">
<div style="text-align:center;">
<select name="subject" size="0">
<option selected="0" value="">Select Subject</option>
<option value="bangla">Bangla</option>
<option value="english">English</option>
<option value="physics">Physics</option>
<option value="chemistry">Chemistry</option>
<option value="math">Mathematics</option>
<option value="biology">Biology</option>
<option value="gk">General knowledge</option>
</select>
</div>
<br /><br />
<label for="question">Write Down the Question below</label>
<textarea name="question" rows="3" cols="40"></textarea><br /><br />
<label for="ans">Options</label><br /><br />
<label for="option1">a.</label>
<input type="text" name="option1" size="40" /><br />
<label for="option2">b.</label>
<input type="text" name="option2" size="40" /><br />
<label for="option3">c.</label>
<input type="text" name="option3" size="40" /><br />
<label for="option4">d.</label>
<input type="text" name="option4" size="40" /><br /><br />
<label for="correct">Correct.</label><br />
<input type="text" name="correct" size="40" /><br /><br /><br />
<div style="text-align:center;">
<input type="submit" name="submit" value="Submit Question" />
</div>
<br />
<br />
</form>
</div>
</div>
</body>
<?php
}
else
{
header("location: admin.php");
}
?>
<?php
include("includes/footer.php");
?>
和 Javascript 文件是
function valide()
{
var subject=document.forms["qform"]["subject"].value;
var question=document.forms["qform"]["question"].value;
var option1=document.forms["qform"]["option1"].value;
var option2=document.forms["qform"]["option2"].value;
var option3=document.forms["qform"]["option3"].value;
var option4=document.forms["qform"]["option4"].value;
var correct=document.forms["qform"]["correct"].value;
if(subject == null || Subject == "Select Subject")
{
alert("Select subject Type");
return false;
}
else if(question==null || question=="" || question.length<5)
{
alert("Insert Valid question");
return false;
}
else if(option1==null || option1=="")
{
alert("Insert Option 1.");
return false;
}
else if(option2==null || option2=="")
{
alert("Insert Option 2.");
return false;
}
else if(option3==null || option3=="")
{
alert("Insert option 3.");
return false;
}
else if(option4==null || option4=="")
{
alert("Insert option 4.");
return false;
}
else if(correct==null || correct=="")
{
alert("Insert correct option.");
return false;
}
}
