[PHP] Even more dynamic page
Is there some way of making PHP even more dynamic? What I would like is that selecting a value from a box would change some info on the page - without having to click a refresh button or something like that. Or do I have to resort to javascript for such things?

Thanks,
So simple - giving it more thought than before rushing off to work I would

[PHP] Searching for array keys
What's the best way of finding out if a specific array key is in an array?
I have an associative array which *may* look like
(car =>saab, house => mansion, countyW=> A) but can equally well look like
(boat => daycruiser, house => flat, county => B).
I want to find out if the key "car" is in the array and do something if it
is.
I found:
$os = array ("Mac", "NT", "Irix", "Linux");
if (in_array ("Irix", $os)){
;
}
But that only works on the values. But it is exactly what I want to do on
keys instead.
Suggestions?

This is taken from PHP Developers Cookbook. Don't ask me exactly what it
does, because I don't know. I think I can grasp the basics of it though.
It isn't fool proof tho.

[PHP] Autoupdate of page
IS there a standard way of "auto-updateing" the contents of a page after a
databas insert or edit? Do a SELECT updates the contents I can update
tables I've noticed. Contents in select boxes (as in
while ($row = mysql_fetch_row($secquery_res)) {
print "$row[0]";
}
)
is not automatically updated to match edits or inserts done on the same
page. You have to initialize the select box again. Or is there another way?

Do you have permission to read the /tmp catalog? Otherwise you may get that

[PHP] BASIC function question
I have a function on an include page that says
function update_stuff($database)
{
include("includes/connect.inc.php");
include("config/db.conf.php");
$query="SELECT * FROM $database";
$query_res=mysql_query($query, $mysql_link);
$isequip=mysql_num_rows($query_res);
}
If I call it from a script as
update_stuff(equipment);
I don't get any result (I want to page to automagically update it's
contents) while if I include the query lines after each edit case
it does update the page contents.
I'm missing something basic, but what?

Thanks James!
You started me off in the right direction. And ... with a few beers less in
the brain (and a look at php.net and PHP Developers Cookbook) I finally
found that mktime actually increments dates correctly.
So, given that $month, $day and $year are valid and that we want to add 10
days to the output we can do:
echo date ("Y-m-d", mktime (0,0,0,$month, $day, $year)) . "";
for($i=1; $i<=9; $i++) {
$day++;
echo date ("Y-m-d", mktime (0,0,0,$month, $day, $year)) . "";
}
Cheers,
Martin S.

I've looked at INTERVAL but it seems it only deals with one specific date at a time? date=10 : SELECT date+INTERVAL 10 would then mean date=20 Or have I got everything wrong? What I looking at from the value of date=10 ADD other dates for X days on, like this (in a table, each record (row) has more data than the one given) date=2001-04-10 date=2001-04-11 date=2001-04-12 This, if I'm mistaken can't be done with interval, at least not without looping in PHP?

[PHP] Cookie problem
I'm experiencing all kinds of problems with, what we suppose is the cookie
setting. This is the code:
if (isset($authentication)) {
setcookie("status", $status, time()+600);
setcookie("user", $user, time()+600);
setcookie("group", $group, time()+600);
setcookie("authentication", $authentication, time()+600);
setcookie("laston", $laston, time()+600);
}
else {
setcookie("status", "Logged In", time()+600);
setcookie("user", $txtUsername, time()+600);
setcookie("group", $row[4], time()+600);
setcookie("authentication", "YES", time()+600);
setcookie("laston", $row[6], time()+600);
}
(I have not coded this).
What seems to happen is that - with alarming regularity - people are
getting logged off when choosing item from a menu. Either they are thrown
out into the log on-screen or (as has happened to me recently) the app
simply states I'm not logged on even if I am in the middle of using it (and
must have logged on).
I'm not at all familiar with cookies (yet) but suspect that the timing of
the critters could be a culprit. IS this correct?
How do I solve the problem?
