FIX-Php表单提交警报重定向到其他页面

Question

我已经写了一个表单的代码，在提交时打开浏览器中的demo.php标记。我希望表单在不重定向到demo.php的情况下在同一页上生成（谢谢）警报。是否有可能嵌入jquery notificaiton插件？如果是，那么如何？

<?php 
 
error_reporting(0); 
 

 
define('DB_NAME', 'form'); 
 
define('DB_USER', '******'); 
 
define('DB_PASSWORD', '*******'); 
 
define('DB_HOST', 'localhost'); 
 

 
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); 
 

 
if (!$link) { 
 
    die('Could not connect: ' . mysql_error()); 
 
} 
 

 
$db_selected = mysql_select_db(DB_NAME, $link); 
 

 
if (!$db_selected) { 
 
    die('Can\'t use ' . DB_NAME . ': ' . mysql_error()); 
 
} 
 

 
echo "<script type='text/javascript'>alert('It worked!')</script>"; 
 
exit(); 
 

 

 
$value = $_POST['name']; 
 
$value2 = $_POST['email']; 
 
$value3 = $_POST['bio']; 
 

 
$sql = "INSERT INTO form (name, email, bio) VALUES ('$value', '$value2','$value3')"; 
 

 
if (!mysql_query($sql)) 
 
{ 
 
     die('Error: ' . mysql_error()); 
 
} 
 

 

 
mysql_close(); 
 

 
?> 
 

 
<form method="post" action="demo.php" id="form" > \t \t \t  
 
\t \t \t \t 
 
\t \t \t <center><legend><h1> Enter Your Details </h1></legend> 
 

 
      <div class="formelement"> 
 
       <label for="name">Name: </label> 
 
       <input type="text" name="name" id="name" required/> 
 
      </div> 
 
    
 
      <div class="formelement"> 
 
       <label for="email">Email-ID: </label> 
 
       <input type="email" name="email" id="email" required/> 
 
      </div> 
 
\t \t \t 
 
\t \t \t <div class="formelement"> 
 
\t \t \t  <label for="bio">Your Message: </label> 
 
\t \t \t \t <textarea rows="1" cols="15" name="bio" id="bio"></textarea> 
 
\t \t \t </div> 
 
\t \t \t 
 
\t \t \t <div class="formelement"> 
 
       <input type="submit" value="SUBMIT" class="submit"/> 
 
      </div> 
 

 

 
</form>

Answer 1

尝试改变

<form method="post" action="demo.php" id="form" > 

到

<form method="post" action="" id="form" > 

它将发布的形式相同的文件，所以不重定向到其他页面

内 -

$db_selected = mysql_select_db(DB_NAME, $link); 

if (!$db_selected) { 
    die('Can\'t use ' . DB_NAME . ': ' . mysql_error()); 
} 
echo "<script type='text/javascript'>alert('It worked!')</script>"; 
$value = $_POST['name']; 
$value2 = $_POST['email']; 
$value3 = $_POST['bio']; 

$sql = "INSERT INTO form (name, email, bio) VALUES ('$value', '$value2','$value3')"; 

$result=mysql_query($sql) or die('Error: ' . mysql_error()); 

if ($result) 
{ 
echo "<script type='text/javascript'>alert('success!')</script>"; 
} 
mysql_close(); 

您可以使用jQuery的ajax表单提交0
