Here's a small snippet showing how it works, I hope:
foreach ($DPRpriority as $item => $value) {
echo "<li> ".$item.": ".$value['name']." selected:
".$value['selected']." </li>\n";
}
Question 1: when did we have to add [] to a <input> name to turn it into
an array?
<input type="checkbox" name="DPRlocationdetails[]" value="Unknown">
According to phpinfo() it still comes out as
$_POST['DPRlocationdetails'] without [].
Are the [] necessary?
----------------------------------------------
Question 2:
I was looking at some code in the Manual, where someone used isset and
is_array.
How necessary is if(isset($_POST['DPRlocationdetails']))
and then to use: if(is_array($_POST['DPRlocationdetails']))
That seems like over kill?
----------------------------------------------
Question 3:
My code works, perfectly. In this case, I decided to attack some
check-boxes first. The resulting function will work for <select
multiple> too..
Does anyone see me doing something wrong in my code below?
My questions are:
Is this the only way to pass "Unknown", "Family Home" or "Apartment"
into the function?
Is this correct?
---- if ($_POST['DPRlocationdetails'] == "Unknown")
Somebody once told me I had to do it this way?
---- if ("Unknown" == $_POST['DPRlocationdetails'])

--------------------snip---------------------------
<form action="foo.php" id="DPRform" method="post"><input value="Update"
type="submit">
<input type="checkbox" name="DPRlocationdetails[]" value="Unknown" <?php
filter_value($_POST['DPRlocationdetails'],"Unknown"); ?>> Unknown
<input type="checkbox" name="DPRlocationdetails[]" value="Family Home"
<?php filter_value($_POST['DPRlocationdetails'],"Family Home"); ?>>
Family Home
<input type="checkbox" name="DPRlocationdetails[]" value="Apartment"
<?php filter_value($_POST['DPRlocationdetails'],"Apartment"); ?>> Apartment
</form>
<?php
function filter_value($tofilter,$tofind) {
foreach($tofilter as $value){
if ($value == $tofind) echo "checked";
}
}
?>
The [] are necessary if there are going to be multiple occurrences of an
input with the same name, hence the [] to allow your php script to
extract all of the occurrences.
Using isset and is_array comes in handy to help you handle the incoming
var properly. If it IS set, you then have to check if there is only one
value (hence a string) or if there are multiple values (an array).
#3 - no idea what you are asking.

Just curious: what is keeping 5.3.22 and 5.4.12 from being released?
Are there any issues?

As a look on qa.php.net or the box on the top right of php.net tells we
have RC2 for both out, you can also see in the repo that the release is
being prepared:
http://git.php.net/?p=php-src.git;a=blobdiff;f=NEWS;h=d3a3e9fa0f344d9b736ea17ce408df6b02e8b561;hp=c4262020de69b7a93b8fcf4923e85194756435a7;hb=0183c29cb3921926855ed6f5e7cea7851fb8a5a1;hpb=904d2202eaecb7c300c36f37ebc5503513220c09
Please test the RCs and provide test feedback. Thanks.

We had 5.4.12 RC2 last week, due to recent SOAP fixes we had to pull in,
and will have 5.4.12 GA this week.

OK. Johannes' reply made me think I mistook the final RC for the
release, but you seem to indicate there was indeed a little delay.
For Johannes: building 5.3.22 and 5.4.12 (both NTS, Windows) right now.
I will report back if I run into something.

I cannot find button2 in phpinfo() when I click it. I was hoping to find
a $_POST["button2"] value.
What am I doing wrong?
<input type="button" name="button2" id="button2" value="Print Mode"
onclick="formSubmit()">
I really wanted to use a button to pass a different condition than a
<input type="submit">

Use a different value or name on the <input type="submit"/> button. Don't use
JavaScript to trigger the form like that. Its not necessary and will bite you
in the ass if ypu get a visitor who browses without JavaScript, which can
include security aware users, blind users, etc

What is the difference between?
if (empty... http://www.php.net/manual/en/function.empty.php "Determine
whether a variable is empty"
and
if (isset... http://php.net/manual/en/function.isset.php "Determine if a
variable is set and is not *|NULL|*"
I have an <input type="radio" value="something">.
If it is not checked, it is NOT empty, because it has a value, right?
But it is NOT set, right?
Is this empty, because it's value is ""?
<input type="text" value="">
Just trying to understand ... :)

I like the explanation on the empty page:
"No warning is generated if the variable does not exist. That means
empty() is essentially the concise equivalent to !isset($var) || $var
== false."
> I have an <input type="radio" value="something">.

Some of the form elements (e.g., checkboxes, radio's) are a little tricky:
http://stackoverflow.com/questions/476426/submit-an-html-form-with-empty-checkboxes
When unchecked, no GET or POST variable is present to represent their value.

A text field would be present in the GET or POST super globals, and if
empty (the user did not add input), the empty function would return
true because an empty string is one of the values that evaluates to
false:
- "" (an empty string)
- 0 (0 as an integer)
- 0.0 (0 as a float)
- "0" (0 as a string)
- NULL
- FALSE
- array() (an empty array)
- $var; (a variable declared, but without a value)
