Hi,

How would i check to see if any decimal points exist in a 'posted' field value?

i.e.

98.0 = Bad

90.8 = Bad

90 = Good

Thanks for the reply.

I was hoping to output an error message if a decimal value was found.

Basically I only want users to be able to enter a 3 digit number into a form field and prevent any other values being input i.e. only numbers like ("455" or "635") NOT "54.0".

Hope this makes sense.

Compare the result from intval() with the original.
