You had it pretty close but try and make a few minor changes to it I've
tested the function below and it works for what you are trying to do. I
am not sure of a way to test for the null with eregi other than putting
and or statement in.
if (eregi('^[0-9]+$', $_POST["gamt_$i"]) || $_POST["gamt_$i"] == null){
}

Subject: [PHP] Simple ereg question
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
