unknowngiver · 04-07-2006, 03:46 PM

HEY
i am trying to learn php and i tried making a small script that tells the user to type in a number...and checks if its an integer..if its not an integer it gives an error..but its not working...no matter wt they enter..it says that its not an integer
here is the code

PHP Code:

  
 
Please enter some numbers..ONLY NUMBERS<br>

        <form action="<?$_SERVER[PHP_SELF]?>" method='post'><br>

            <input type='text' name='input'> <br>

            <input type='Submit' name='Submit' value='Submit'>

        </form>

 
<?

$stuff=$_POST['input'];

$submit= $_POST['Submit'];

$get = gettype($stuff);

$get=gettype($stuff);

if (isset($submit)){

????: NamePros.com http://www.namepros.com/programming/184870-wts-wrong-here.html
if ($get != 'integer') {

echo "You posted $stuff and its not an integer";}

else

{echo "thanks " ;}

}

else 

{}

 
 
?>

grr but y isnt the gettype not working? y isnt recognizing numbers as integers?

Why does it matter? You can use the is_whatever family of functions to do it more efficiently.

unknowngiver · 04-07-2006, 06:51 PM

I think it's not working because the post variable is handled as a string.

and using is_int will produce the same result. Btw, to quote the PHP manual:
????: NamePros.com http://www.namepros.com/showthread.php?t=184870

Quote:

Never use gettype() to test for a certain type, since the returned string may be subject to change in a future version. In addition, it is slow too, as it involves string comparison.

Instead, use the is_* functions.

However, you could use (int)$_POST['input'] , or intval($_POST['input']). That would solve your problem...almost. If anything other than numbers are posted..intval or (int) will return 0, which will still pass as an integer.

A good way to do it would probably be to do a preg_match

PHP Code:

  <?php

 
$stuff = '9';

 
if(!preg_match('/([0-9]+)/', $stuff))

{

  echo "You posted $stuff and its not an integer";

}

else

{

  echo "thanks ";

}

 
?>
