Hey freaks.

 

I have a basic form :

Limit Number Of Posts : </td><td><select name=\"limit\"> <option value='1'".($limit == '1' ? ' SELECTED' : '').">1</option>
								<option value='2'".($limit == '2' ? ' SELECTED' : '').">2</option>
								<option value='3'".($limit == '3' ? ' SELECTED' : '').">3</option>
								<option value='4'".($limit == '4' ? ' SELECTED' : '').">4</option>
								<option value='5'".($limit == '5' ? ' SELECTED' : '').">5</option>
								<option value='6'".($limit == '6' ? ' SELECTED' : '').">6</option>
								<option value='7'".($limit == '7' ? ' SELECTED' : '').">7</option>
								<option value='8'".($limit == '8' ? ' SELECTED' : '').">8</option>
								<option value='9'".($limit == '9' ? ' SELECTED' : '').">9</option>
								<option value='10'".($limit == '10' ? ' SELECTED' : '').">10</option> </select></td><tr>
		<td> 

 

Is there a way of making sure the number that is submite is a int?

 

would this work int($number); ??
