    PHP simple question : undefined index

    Firstly, sorry that I didnt know where else to post this question.

    Need help w/ PHP 4.2.0

    I'm following this tutorial here, creating form and processing the info on that form.

    form.html
    Code:
    <html>
    <head>
    <title>Add Elements to a form</title>
    </head>
    
    <body>
    <h1>Welcome to this Site</h1>
    
    <form action="processForm.php" method="POST">
     Your name: <input type="text" name="name">
     Your age:   <input type="text" name="age">
     <input type="submit" value="Enter">
    </form>
    
    </body>
    </html>

    processForm.php

    Code:
    <html>
    <head>
    <title>Process Form Data</title>
    </head>
    
    <body>
    <h3>Your info has been processed</h3>
    
    Hi 
    <?php 
    echo $_POST["name"]; 
    ?>.
    
    You are 
    <?php 
    echo $_POST["age"]; 
    ?> years old.
    
    <br>
    <a target="_new" href="name.php?name=<?php echo $_POST["name"]?>">Show name</a>
    
    </body>
    </html>
    name.php
    Code:
    <html>
    <head>
    <title>name.php</title>
    </head>
    <body>
    
    <p>Applicant:
    <?php 
    echo $_POST["name"];
    ?>
    
    </body>
    </html>
    After entering both the name and age in the form (form.html) and hitting the Submit Query button, PHP processes the info and generates a file to display the name and age. There's also a link on that page to a new page which opens in a new window (name.php).

    The link (show name) works, but the new page (name.php) displays this error:
    Applicant:
    Notice: Undefined index: name in F:\myphp\name.php on line 9


    It's supposed to display the name entered in the form.

    What gives?

    Thanx.

    Moved to the tech forum.

    Once you click that link, the data your are looking for is in the query string, not the form.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
