提交表单后显示
“您的数据已提交，我们会尽快与您联系！！”
同时，表单输入字段保留在页面中（字段上仍然存在提交的数据）
提交后如何清除输入字段中的数据
这是我的代码：
<?php
if(isset($_POST['name']))
{
include_once("config.php");
$name=$email=$phone=$uploadresume="";
$nameErr=$emailErr=$phoneErr=$uploadresumeErr="";
function test_input($data)
{
$data=trim($data);
$data=stripslashes($data);
$data=htmlspecialchars($data);
return $data;
}
if ($_SERVER['REQUEST_METHOD']=="POST"){
$valid=true;
//name validaton
if(empty($_POST["name"]))
{
$nameErr="* Name is Required";
$valid=false;
}
else
{
$name=test_input($_POST["name"]);
if (!preg_match("/^[a-zA-Z ]*$/",$name))
{
$nameErr = " Only letters and white space allowed";
$valid=false;
}
}
//Email Address validaton
if(empty($_POST["email"]))
{
$emailErr="* Email is Required";
$valid=false;
}
else
{
$email=test_input($_POST["email"]);
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email))
{
$emailErr=" Enter a valid Email ID";
$valid=false;
}
}
//Mobile no validaton
if(empty($_POST["phone"]))
{
$phoneErr="* Mobile no is Required";
$valid=false;
}
else
{
$phone=test_input($_POST["phone"]);
if(!preg_match("/^(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?\d{3}[\s-]?\d{4}$/i",$phone))
{
$phoneErr="*Enter a valid contact no";
$valid=false;
}
}
if(empty($_FILES["filename"]['name']))
{
$uploadresumeErr="* Upload Your Resume";
$valid=false;
}
else
{
$fname_arr = explode('.',$_FILES["filename"]['name']);
$fileext = $fname_arr[count($fname_arr)-1];
$ext_arr = array('doc','pdf');
if(in_array($fileext,$ext_arr))
{
$uploadresume=test_input($_POST["filename"]);
}
else{
$uploadresumeErr="* Upload only doc or pdf files.";
$valid=false;
}
}
if($valid)
{
// Add user info into the database table, claim your fields then values
$sql = mysql_query("INSERT INTO jobopening(name, email, phone,applieddate,Appliedjob)

$id = mysql_insert_id();
$to = "example@example.co.in";
// Change this to your site admin email
$from = "$_POST[email]";
$subject = "Applied for DataEntry FROM $_POST[name] ";
//Begin HTML Email Message where you need to change the activation URL inside
// Get all the values from input
$name = $_POST['name'];
$email_address = $_POST['email'];
$phone = $_POST['phone'];
// Now Generate a random string to be used as the boundary marker
$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";
// Now Store the file information to a variables for easier access
$tmp_name = $_FILES['filename']['tmp_name'];
$type = $_FILES['filename']['type'];
$file_name = $_FILES['filename']['name'];
$size = $_FILES['filename']['size'];
// Now here we setting up the message of the mail
$message = "
\n\n Applied For DataEntry
\n\n Name: $name
\n\n Email: $email_address

$file = fopen($tmp_name,'rb');
// Now read the file content into a variable
$data = fread($file,filesize($tmp_name));
// close the file
fclose($file);
// Now we need to encode it and split it into acceptable length lines
$data = chunk_split(base64_encode($data));
}
// Now we'll build the message headers
$headers = "From: $from\r\n" .
"MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed;\r\n" .
" boundary=\"{$mime_boundary}\"";
// Next, we'll build the message body note that we insert two dashes in front of the MIME boundary when we use it
$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n";
// Now we'll insert a boundary to indicate we're starting the attachment we have to specify the content type, file name, and disposition as an attachment, then add the file content and set another boundary to indicate that the end of the file has been reached
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$type};\n" .

"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .

// Thats all.. Now we need to send this mail... :)

提交表单后为什么不尝试重新加载页面？
-
@Sulthan Allaudeen 提交表单后如何使用页面重新加载？
-
在 if 条件下 - if(@mail) 使用 header('Location: example.com/');这是链接in2.php.net/manual/en/function.header.php
-
如果他重新加载，需要编写单独的代码来显示成功消息
