concatenate object variable name

[Bosconian]

I have form values stored in an object.

I have a set of numbered form fields:

specialty1
specialty2
specialty3

I need to loop through these, check for content and process accordingly. I
can't figure out how to correctly concatenate the number to the end of the
field name. For example:

for ($i = 1; $i <= 3; $i++) {
if (eval("$node->specialty" . $i)) {
//do something
}
}
I know eval is slow, but what other options are there?

Thanks.

I suppose you stored them in separate variables. It may be handier to
use an array for that.

When calling a method, you can pass the array index as a parameter.

As Willem said - use an array. For instance:
<form action="..." method="post">
<b>Specialty 1</b><input type="text" name="specialty[]"><br>
<b>Specialty 2</b><input type="text" name="specialty[]"><br>
<b>Specialty 3</b><input type="text" name="specialty[]"><br>
(other stuff)
</form>

In your target's code,

$specialty=$_PO ST['specialty'];

The three (if they are filled in) will be in $specialty[0],
$specialty[1] and $specialty[2].

When concatenating objects in the above example simply

$node->specialty . $i

eval is not needed.
