Good. What you chose to do is exactly what I do except for one
thing... :
> $sql = "select department_name from Departments";
I generally grab the primary key column value as well, in the same
query, and then I use that as the "value" attribute for the
tags:
> while($row = mysql_fetch_array($sql_result))
> {
> $department = $row["department_name"];

while ($row = mysql_fetch_assoc($result)) {
$dept_id = $row['department_id'];
$dept_name = $row['department_name'];
echo "$department_name\n";
}
The reason I do this is because I end up using the ID far more than the
"name" of a database record -- while I might echo the "name" to the user
where needed (such as in the above dropdown listbox), the ID comes in
handy as a reference in hyperlinks, form fields, etc -- it provides
something that I've discovered is really missing in writing HTML-based
applications: a unique handle on an object. This is very hard to
replicate given the statelessness of HTTP, but with a database record's
primary key, you always have this unique identifier by which to refer to
the object. and a number is more pithy than a name.
It'll avoid situations where someone enters the same "name" value twice,
too. But it's not really a big deal unless you're doing a lot of work
with a lot of data.

If you can't have enough respect for people trying to help you by answering the simplest of questions (that should have been given in your original question anyway), you don't deserve an answer. Here are Mr. Wong's questions again (very appropriate questions at that). Perhaps if you offer him a sincere apology, thank him for his time, and *answer* *his* *questions*, he might be willing to forgive your poor attitude and offer you some help. >>There are two things you need to know: >> >>1) How to construct a select list in HTML >>2) How to retrieve the info from the db >> >>What are you having problems with? >> If you don't know a damn thing, that's fine.

I was merely stating what you need to know to be able to solve your problem. And then I asked which part you were having trouble with. You have given no indication in your post as to what level of competence you have in PHP and HTML. The only hint was that the example you quoted was beyond your understanding. You have given no indication of what you have done and did or didn't work. So how is one supposed to respond to your post? a) give you a solution, which may or may not be beyond your understanding? b) or prod you along the right direction with a request for more information? -- Jason Wong -> Gremlins Associates -> www.gremlins.com.hk Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * /* The world is coming to an end--save your buffers! */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
