If, And, Or code for data entry

[jcage]

I have a drop down box with 'Incomplete', 'Resolved' and 'Complete' as
part of my $status variable on a form and a text box called
'$datecomp' that passes the data from both variables to a MySQL
database.

How might I include an 'if' statement where if the drop down selection
for variable $datecomp is 'Incomplete' or 'Resolved', an error message
is displayed on the data entry confirmation page that requests the
user to click their browser 'back' button and enter a date in the
'datecomp' field? I was trying to modify the following code but so
far, without any luck. In other words, if 'status' = Complete or
Resolved, trigger the error on the confirmation page where a user
clicks their back button and either enters a date in the datecomp
field OR leaves the drop down box as Incomplete.

thanks,
John

if (!$datecomp || and $status="Complete" or "Resolved")
{
echo 'You must enter a DATE for items marked Complete or
Resolved.<br />'
.'Please click the browser BACK button, fill in a Complete/
Resolved date and try again.';
exit;
}

Solved this puzzle (though it may not be the best example of code
writing) and thought I'd put the solution here in hopes of helping
someone else in a similar bind.. :-)

if ((($status == "Complete") or ($status == "Resolved") and ($datecomp
== "")))
{
echo 'All items marked COMPLETE or RESOLVED must have a date
entered.<br />'
.'Please click the browser BACK button, fill in the date and
try again.';
exit;
}

if (!$datecomp && ($status == 'Complete' || $status == 'Resolved'))
....use '=' for assignment and '==' for comparison.

The variable passed to PHP is $_GET['datecomp'] or $_POST['datecomp'],
not $datecomp. (register_globals is evil and should be turned off).

There's no meaning to a subexpression like: "Complete" or "Resolved".
Think of it as: If status is Complete or status is Resolved, then ....

if (!$datecomp || and $status="Complete" or "Resolved")

if (isset($_GET['datecomp'] && ($_GET['status'] == "Complete" || $_GET['status'] == "Resolved"))

{
echo 'You must enter a DATE for items marked Complete or
Resolved.<br />'
.'Please click the browser BACK button, fill in a Complete/
Resolved date and try again.';
