提交表格后显示

“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(字段中存在仍然存在的数据)

如何在提交

后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 = "&nbsp;&nbsp;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="&nbsp;&nbsp; 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)

         // Now Open the file for a binary read

         // 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" .

将$ _POST存储在

中的变量中
 if(isset($_POST['name']))
 {
   $post_val=$_POST;
  ---------

然后,发送电子邮件后取消设置$post_val

  if (@mail($to, $subject, $message, $headers))
  {
   unset($post_val);
     ?>

显示$_post_val

的值
  <input type="text" name="name"  value="<?php echo $_post_val["name"]?>"/>
  <input type="text" name="email" value="<?php echo $_post_val["email"]?>"/>   
  <input type="text" name="phone" value="<?php echo $_post_val["phone"]?>"/>

您正在使用$_POST变量设置字段的值。提交表单后,将填充$_POST数组。因此,在提交后加载页面时,将设置输入的值。你需要删除它们。

更改

 <input type="text" name="name"  value="<?php echo $_POST["name"]?>"/>
 <input type="text" name="email" value="<?php echo $_POST["email"]?>"/>   
 <input type="text" name="phone" value="<?php echo $_POST["phone"]?>"/>      

 <input type="text" name="name"  value=""/>
 <input type="text" name="email" value=""/>   
 <input type="text" name="phone" value=""/>

将数据插入数据库并发送电子邮件后,您应该重定向到同一页面

header("location:".$_SERVER['PHP_SELF']);
