2 ifs embedded?

I need this to say : If row notes is not empty and is alpha echo notes

How do I get the is alpha part in here;

If (!empty($row['notes'])) {


echo(" $trimNotes ");

}

I tried.....

If (IsAlpha($row['notes'])) {


echo(" $trimNotes ");

}

But it broke the whole script.

I'm not really sure what you are trying to do here? Is it that you want
to have nested queries, or only do something if both conditions have
been met?

You can write it in one IF statement

If (!empty($row['notes']) && IsAlpha($row['notes'])) {

}

I tried that and this one:

If (!empty($row['notes']) && ctype_alpha($row['notes']))

It didn't display the notes at all...

And this one...doesn't display if the field has a 0 in it but I still need =
it to?

If (!empty($row['critical']) && ctype_alnum($row['critical']))

Hey Teri,
Could the return from the db have a space or something in the value? Perhaps

If (!empty($row['critical']) && ctype_alnum((int)$row['critical']))

might work

It's got me stumped, tried it and it still will not echo if the field has a=
0 in it:

If (!empty($row['critical']) && ctype_alnum((int)$row['critical'])){ =
echo(" Critical violations found: ". $row['critical'] .". ");

empty() regards 0 as an empty value... From the manual:

[quote]
The following things are considered to be empty:

* "" (an empty string)
* 0 (0 as an integer)
* "0" (0 as a string)
* NULL
* FALSE
* array() (an empty array)
* var $var; (a variable declared, but without a value in a class)

That all depends on WHAT it is you are getting.

Can you tell us WHAT you are getting? Not simply that "I get the int
that is in the field from the db". We don't have any idea what that
value is. Only you know that...

So, the only thing you will see is a number? Correct? What is the
range that the number will fall between?

And, does zero mean anything different then 1, 2, 3...

If, all you want to do is make sure that $row['critical'] is a number
and the value is within a range of numbers, so this.

if (
isset($row['critical']) &&
is_numeric($row['critical']) &&
in_array($row['critical'], range(0, 200))
} {
...
}

Remember that empty() does clever stuff for you.

empty('') == true
empty(0) == true
empty('0') == true
empty(1) == false
empty(2) == false
empty('foo') == false

I suspect you were just being bitten by a misconception of what empty()
was supposed to do when you passed certain values to it.

isset() and empty() are subtly different.
