请缩小你的代码到实际上令人失望的地方。也试着提出一个明确的问题。 –

I don't know if i understood you..without javascript you can simply do as follows:

的index.php

<html> 
    <head> 
     <title>whatever</title> 
    </head> 
<body> 
<form name="gt" id="gt" action="check.php" method="post" > 
    <!-- notice the form action is in the check.php make sure you give correct location--> 
    <table> 
    <tr> 
     <td>Userid</td> 
     <td><input type='text' name='userid' id='userid' ></td> 
     <td></td></tr> 
    <tr><td>name</td> 
     <td><input type='text' name='name' id='name' ></td> 
     <td></td> 
    </tr> 
    <tr><td>age</td> 
     <td><input type='text' name='age' id='age'></td> 
     <td></td> 
    </tr> 
    <tr><td>dob</td> 
     <td><input type='text' name='dob' id='dob'></td> 
     <td></td> 
    </tr> 
    </table> 
<input type='submit' value='Submit'> 
</form> 
</body> 
</html>

check.php

<?php 
$userid = $_POST['userid'];//since the form has post method in index.php 
$name = $_POST['name']; 
$age = $_POST['age']; 

//You can either put it to database by mysql query or just display as below 
echo $userid; 
echo "<br/>"; 
echo $name; 
echo "<br/>"; 
echo $age; 
echo "<br/>"; 
?>
