Not able to redirect to next page

问题

I am using Win XP os and XAMPP. I was using eclipse as the editor. In Eclipes I was not able to redirect next page so now I have installed Zend Development Environment.

Now also I am getting the same problem.

My Code is

HomePage.php

<html>
<body>
<form name="Form1" id="FormId" action="Welcome.php" method="post">
    name : <input type="text" name="txtName">
    Phone Number : <input type="text" name="txtPnum">
    <input type="submit" name="SubmitIt" value="Submit It">     
</form>
</body>
</html>


And Welcome.php is

<?php
    ob_start(); 
    session_start();    
    if(!($_SESSION['UName']))
    {
        $_SESSION['UName']=$_POST['txtName'];
    }
    if(!($_SESSION['Ph Num']))
    {
        $_SESSION['Ph Num']=$_POST['txtPnum'];
    }
?>
<html>
<body>
Welcome <?php   
    if(isset($_SESSION['UName']))
    {
        echo  $_SESSION['UName'];
    }
    else
    {
        echo "Session not set<br/>";    
        echo "{$_SESSION['UName']}";        
        echo "The session contains <br>";
        print_r($_SESSION);
    }           
    ?>
</body>
</html>

Its working fine (redirecting to next page) in the Browser but its not working in the debug mode. Both in Eclipse and Zend Development Environment.

Instead of show the content of the next page, it showing the page name.(Welcome.php in my example).

Should I need to install any other extra softwares or code itself worng.... Whats the problem. Please suggest me.

Thanks in advance....!

回答1:

which part is supposed to make a redirection, i don't see any header('Location: redirect.php') or something

and why do you use ob_start() here .

you didnt release the output buffer add ob_get_clean(); in the end

<?php
    ob_start(); 
    session_start();    
    if(!($_SESSION['UName']))
    {
        $_SESSION['UName']=$_POST['txtName'];
    }
    if(!($_SESSION['Ph Num']))
    {
        $_SESSION['Ph Num']=$_POST['txtPnum'];
    }
    ob_end_flush();
?>
<html>
<body>
Welcome <?php   
    if(isset($_SESSION['UName']))
    {
        echo  $_SESSION['UName'];
    }
    else
    {
        echo "Session not set<br/>";    
        echo "{$_SESSION['UName']}";        
        echo "The session contains <br>";
        print_r($_SESSION);
    }           
    ?>
</body>
</html>

try to add this at the end of your code i am pretty sure it is because you are not releasing the output buffer, although i think it should have done it automatically

echo ob_get_clean();

Update:

I am not really sure why you are using the $_SESSION variable here, but is you want to fix the problem, you can use for example $uname instead of $_SESSION['UName'];

Welcome.php

<?php // at the beginning of your file, no spaces or newline
    session_start();
    $uName=$_POST['txtPnum'];
    $txtPnum=$_POST['txtPnum'];
    $_SESSION['UName'] = $uName;
    $_SESSION['PhNum'] = $uName;
?>
<html>
<body>
Welcome <?php echo  $_SESSION['UName']; ?>

</body>
</html>

you get rid of the ob start since you are still debugging your code. and try one step at a time. Wish you good look.
