Did you try this syntax yet?
The with the ^ and $ search matching beginning and end
I tested out the code myself and it worked fine.
http://www.theoutersphere.com/testing/testnumbers.php
//here is the exact code that I used
echo $_POST[vari] ."<br>";
if (eregi('^[0-9]+$',$_POST[vari]) || $_POST[vari] == null)
{
echo " continue This is a valid number";
}
else
{
die("Non-numeric data entered in grass entry field(s).");
}

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
