Hello folks,
I'd like to verify input data transferred from a form and make sure it is numeric data or null before my program executes. I am using this syntax, which doesn't work:
for ($i=1;$i<=3;$i++)
{
if (ereg('[0-9]+','$_POST["gamt_$i"]'))
{
continue;
}
else
{
die("Non-numeric data entered in grass entry field(s).");
}
}
No matter what I put in the fields, the program dies and I get the death message. What can I do to fix this?
TIA
Bob Harvey
