$_post[''];

[c0d3m3]

hey php builders,
i know that if you go
<?php

echo "a word is: " . $_POST['word'];

?>

<form method="POST"> 
<input type="text" name="word"><br>
<input type="submit"> 
</form> 

that it will output anything u type in the form text space.
but say you wanted to get information on someone, like their age and store it in a variable.. is that possible?
because it doesnt let me do this:
<?php
$age;
?>

<form method="POST">
<input type="text" name="age"><br>
<input type="submit">
</form>

// then later in the file i would go
Another year passes you are now:
<? $age++; $age ?>

that doesnt work, i already tried it, but how would i write it so it would work? so that i can enter 10 into the text form and it would print 11..?

<?php
if (!isset($_POST['submit'])) {
  ?>
   <form method="POST">
<input type="text" name="age"><br>
<input type="submit" name="submit">
</form> 
  <?php
} else {
  $age = $_POST['age'];
  echo 'Hi you are '.$age.' next year you will be '.++$age;
}

?>

Try that
