get name of field in GET [Resolved]

[ober0330]

I'm submitting a form, and the textboxes located on that form are grabbed from a DB, therefore they are not going to be a designated name, necessarily.

So when I go to update these fields in the DB, can I grab the name of the textbox (which corresponds to the field in the DB) out of the GET array?

I hope that makes sense... :(

Nevermind, I got it:

while($curarr = each($_GET))
{
$curkey = $curarr['key'];
$curval = $curarr['value'];;
echo $curkey;
echo $curval . "<br>";

Easier:
while(list($curkey, $curval) = each($_GET))
Even easier:
foreach($_GET as $curkey => $curval)

yeah... I found out about the list thing after posting that. Thanks :)

I just gave you the method for doing this in a thread yesterday...

[ober0330]

umm... yeah. You did. I guess that wasn't exactly what I was looking for... but now that I go back and look at that, that's where I was heading. Sorry for the double post.

I'm new at PHP and I'm still getting a handle on it (hence the barrage of n00bie questions :()

uhh, whats the advantage of using the whille...wend over using do while...loop?

[ober0330]

First of all, this is PHP which is based off of C so you don't have "wend" or "loop".

The advantage of using a While instead of a Do While is that this checks to see if anything has actually been passed from the form.

There is no while...wend or do while...loop in PHP. The two options in this case are foreach(...) or while(...). As for which is an advantage over the other... <shrug /> It's just a matter of coding style I think.

PHP is more flexible than you people think.

Here's every legal loop construct.
while(cond) {
statements
}
while(cond):
statements
endwhile;

do {
statements
} while(cond);

for(init; cond; expr) {
statements
}
for(init; cond; expr):
statements
endfor;

// Only PHP 4+
foreach(array as [key =>] value) {
statements
}

Note: for do...while and foreach loops the : syntax is not mentioned in the reference. It might still work.

foreach is shorter and more readable. It only exists since PHP 4, which is why the other syntax is known.

I think the foreach syntax is also easier to understand and see what's going on. I think if someone was new, the whol list() thing would confuse them more than the foreach() would.
