[SOLVED] INPUT BOX FOR INTEGER VALUES

It can't be done....

 

If you have a text input element on a page and only want numbers in there you have to use javascript. That can be turned off so you shouls always validate the data in the php script accepting it.

^^^ exactly what mariner said.

Here is an example of the javascript you can use to remove all characters except numbers from a field when the user moves off the field. However, as ToonMariner stated you should do the same thing on the server-side as well.

 

<input type="text" onblur="this.value=this.value.replace(/\D/g,'');">

I would do a preg_replace on the server side:

 

$_POST['var'] = preg_replace ("/[^0-9]/", "", $_POST['var']);

 

What that says is strip out anything that is not a number (0-9).
