What is wrong with this if test?

[Shelly]

OK, I am at a toral loss after having programmed for forty years.

Here are my results:

selHint_2=1
It is clear that for the second time through the loop ($i=1) that
$index=1 and $selHint_2=1, while for the first pass through ($i=0) $index=0
and $selHint=1. Yet, the " selected " comes up for the first time and not
for the second. It should be the other way around. Any clues?

Shelly
Here is the code:
$numHint_2 = 2;
$hint_2_Lookup = array(0, 1);
$hint_2 = array();
$hint_2[] = " Family member's name";
$hint_2[] = " Mothers maiden name";
$foo = ""; // put in for debugging only
$tmpHint2 = array();
$tmpHint2[] = '<td class="stdBold"' . $readonly . '>';
$tmpHint2[] = '<select name="hint_1" value="" >';
for ($i=0; $i<$numHint_2; $i++) {
$index = $hint_2_Lookup[$i];
if ($index == $selHint_2) {
$sel = " selected ";
} else {
$sel = "";
}
$tmpHint2[] = '<option value="' . $index . '"' . $sel . '>' .
$hint_2[$i] . '</option>';
// next line put in for debugging only
$foo .= 'index=' . $index . ' option value="' . $index . '"' .
$sel . $hint_2[$i]. "<br>";
}
$tmpHint2[] = '</select></td>';

$selHint_2 = $_SESSION['vmHint_2']; // put in for
debugging only
echo "selHint_2=" . $selHint_2 . "<br>"; // put in for
debugging only
echo implode("\n",$tmpHint2)."\n";
echo $foo; // put in for debugging only

index=0 option value="0" selected Family member's name
index=1 option value="1" Mothers maiden

Oops, here is the output:

selHint_2=1 index=0 option value="0" selected Family member's name
index=1 option value="1" Mothers maiden

OK, I fixed it, but I know why it didn't work before.

The if test stuff was in an include file (that is bracketed by <?php ?>.
When I cut and pasted that code into inline code, it worked. The problem
was that the include file was at the beginning of the page, so the test was
before getting any values. Some times the stupid errors are the hardest to
find.

Turn on error_reporting for all errors, warnings and notices.
.... maybe you'll notice some uninitialized variable.

Insert these two lines at the top of your script

error_reporting(E_ALL);
ini_set('display_errors', '1');

<snip> for ($i=0; $i<$numHint_2; $i++) {
$index = $hint_2_Lookup[$i];
if ($index == $selHint_2) {
possible use of unassigned variable?
$sel = " selected ";
} else {
$sel = "";
}
$tmpHint2[] = '<option value="' . $index . '"' . $sel . '>' .
$hint_2[$i] . '</option>';
// next line put in for debugging only
$foo .= 'index=' . $index . ' option value="' . $index . '"' .
$sel . $hint_2[$i]. "<br>";
}
$tmpHint2[] = '</select></td>';

$selHint_2 = $_SESSION['vmHint_2']; // put in for
debugging only
You're assigning to $selHint_2 after you've used the variable in the
test above.
echo "selHint_2=" . $selHint_2 . "<br>"; // put in for
debugging only
echo implode("\n",$tmpHint2)."\n";
echo $foo; // put in for debugging only

Happy debugging :)

This seems to happen quite a bit. I suppose what happens is that you
work on something for ages and get totally bogged down and then, in
desperation, make a post to the group. Then, knowing you have to wait
for a reply, you put the problem to one side and relax. The relaxation
enables you to see the solution.

If you programmed for forty years, you must be tired. ;)

Fact! Those stupid errors are always messing up *my* code. ;)
Try sprinkling a little Modula into a C program. That's why I like
PHP, handling C syntax or Perl if I goof on the last couple of
languages I've done much coding in. Of course, it's forgiving nature
can sometimes get us in trouble too.
