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'])

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

<?php
function filter_value($tofilter,$tofind) {
foreach($tofilter as $value){
if ($value == $tofind) echo "checked";
}
}
?>
