Re: using the $_POST
$_POST assumes that your form has been submitted. I think this is what you were attempting to do:

-- missing a closing head tag
-- missing an opening form tag
-- minor reformatting

Basically, what this does is use a PHP snippet to check if the form has been submitted. If it has, it grabs the form values and displays the welcome message. If not, the form gets displayed.


<html>
<head>
<title>Form</title>
</head>
<body>

<?php

if (isset($_POST['submit'])) {
$name = $_POST['name'];
$age = $_POST['age'];

echo "Welcome $name.<br/>You are $age years old.";
}
else { ?>

<form action="" method="post">
<div>
Name: <input type="text" name="name" />
Age: <input type="text" name="age" />

<input type="submit" value="send" name="submit" />
</div>
</form>

<? } ?>

</body>
</html>

Re: using the $_POST
-- unnecessary parenthesis in your echo statement
-- no closing ">" on your opening form tag
-- extra unneccessary "</font>" tag (don't use <font> use CSS)
-- use isset() to check if the form has been submitted... otherwise, you'll get an error since PHP is checking a variable that doesn't exist yet

Corrected code:

<html>
<head>
<title>Form</title>
<body>

<?php

if(isset($_GET["action"])){

echo 'Data = ' . $_GET['keyword'];

}
?>

<form method="get" action="index.php">


<fieldset>
<legend>Form Data</legend>

<p>
<label for="keyword">Search keyword:</label>
<input type="text" name="keyword" size="25" />
</p>

<p>
<input type="submit" name="action" value="send" />
</p>
</fieldset>

</body>
</html>

You are going to have to rephrase your question. It doesn't seem to make much sense. I did test my code above and I know it works correctly.

What text editor you are using doesn't matter, it's all working with the same code. I am using Textmate on my mac / Notepad++ on a PC. Also, this is very basic script, so you shouldn't need to adjust any server settings.

Just to be clear, here is what it currently does for me:

-- I open the page. The form displays, with an input that asks what search keyword I want
-- I enter something, "test" in this case, and press "send"
-- The page refreshes, and I then get the text "Data = test" at the top of a page, followed by the form.

If that isn't what you were intending, you'll need to explain what you were expecting the code to do. It is working correctly, and I have tested it on two machines. If you are still getting some sort of error, you'll need to explain clearly what issue you are running into.

Re: using the $_POST
OK, a couple questions then...

-- Do you have a server running (you know you have to have a server to display .PHP files correctly, right?). Either you'll need to upload your files to your hosting and view them in your browser, or you'll need to use something like WAMP (http://www.wampserver.com/en/ -- PC) or MAMP (http://www.mamp.info/en/index.php -- for mac).

-- If you are using a server on your local machine, are you actually viewing your files on the server (your URL in the browser should be something like: http://localhost/) or are you just accessing the file directly (the URL in your browser will start with file:///C... etc). If you are trying to access the file directly, it won't work. It needs to be run through localhost.
