[SOLVED] Only Numeric Values??

[DJTim666]

Alright, I am trying to limit people to only enter numbers into the text field. So if they enter 35256 it will take them to the next page, but if they enter, sgsg, it will take them to an error page. I have tried google, but have turned up no results. ! It will be for this site.

 

Any help greatly appreciated.

<?php

if(!is_numeric($variable)) {
die("Incorrect value type");
}

// Rest of code

?>

EEEEEEEEEEEEEEEEEEK, Ok. Maybe it doesn't work rofl. Anymore suggestions?

It works... check your variable you're using.

How are you using it in your code. Post some of your code here. You may have applied in the wrong place/not using correctly.

Hmm, I think I have gotten it correct. But I am getting an error, anyone see anything wrong with the following code?

 

} elseif ($ranNumber == $guess5){

echo $message;

} elseif ($guess5 == ""){

echo $message2;

} elseif ($guess5 > 1000000){

echo $message3;

} elsif (!is_numeric($guess5)){

echo $message4;

}

 

EDIT: Nvm, I see the "e" missing. I fixed it and now it works perfectly. http://contest.trulyours.com/
