try this,Then include your insert query it will work enctype="multipart/form-data"
<form name="form" method="post" action="" onSubmit="submit;" enctype="multipart/form-data">
</form>
<?php
if(isset($_FILES['image']))
{
$errors= array();
$file_name = $_FILES['image']['name'];
$file_size =$_FILES['image']['size'];
$file_tmp =$_FILES['image']['tmp_name'];
$file_type=$_FILES['image']['type'];
$value = explode(".", $file_name);
$file_ext = strtolower(array_pop($value));
//$file_ext=strtolower(end(explode(".",$file_name))); -->this line wnt work bcoz only variable should be passed inside explode
$expensions= array("jpeg","jpg","png","csv");
if(in_array($file_ext,$expensions)== false)
{
$errors="Extension not allowed, please choose a JPEG or PNG file.";
}
if($file_size > 2097152)
{
$errors[]='File size must be excately 2 MB';
}
if(empty($errors)==true)
{
move_uploaded_file($file_tmp,"upload/".$file_name);
**//include here insert query**
echo "Success";
}else
{
print_r($errors);
}
}
?>

第一。不要使用mysql_ *函数，而是使用mysqli_ *。
第二。如果接受任何数据，这是一个非常大的安全漏洞。
第三。你有没有创建这样的变量？ $名称= $ _ POST [ “名称”];
因此，当您想要插入$_POST["name"]时，请执行以下操作：
修改
试试这个。它会死掉，并会为你打印出查询字符串。尝试将其直接复制到mysql中，并对结果进行评论。
function dbEscape($str) {
return mysql_real_escape_string($str);
}
$sql = "INSERT INTO registration(file,name,fname,gender,email,date,mn,pn,address,idnum,ccname,colname,course,year,comname,doj)
VALUES ('".dbEscape($uploadpath)."','". dbEscape($_POST["name"])."','". dbEscape($_POST['fname'])."','". dbEscape($_POST['genred'])."','". dbEscape($_POST['email'])."','". dbEscape($_POST['date'])."','". dbEscape($_POST['mn'])."','". dbEscape($_POST['pn'])."','". dbEscape($_POST['address'])."','". dbEscape($_POST['idnum'])."','". dbEscape($_POST['ccname'])."','". dbEscape($_POST['colname'])."','". dbEscape($_POST['course'])."','". dbEscape($_POST['year'])."','". dbEscape($_POST['comname'])."','". dbEscape($_POST['doj'])."')";
die($sql);
$result = mysql_query($sql);

您的表单不包含enctype="multipart/form-data"，是上传文件的重要部分。
将表单修改为：
<form name="form" method="post" enctype="multipart/form-data" action="" onSubmit="submit;">
这就是您上传无效的原因。
