1+1 ?

[pedrobcabral]

I have a form with get method. My variable ID is assigned to 1 in the url.
The code:

[code]
<?php
$calculate = $_GET[id]+1;
echo "Calculation is: $calculate";[/code]

Gives me the output: Calculation is 1+1 instead of Calculation is 2.
Could you help me? Thank you.

$calculate = $get['id']+1;
echo ...the rest of the code.  I think the quotes might fix it.  If not you can always include
$calculate++ I belive.  That may be wrong though in the second version.

This code works for me:
[code]<?php
<?php
if (isset($_GET['id'])) {
$calculate = $_GET['id'] + 1;
echo $calculate . '<br>';
}
?>
<form>
Id: <input type="text" name="id"> <input type="submit" name="submit">
</form>[/code]
