Whilst "better" is a little subjective, the reason I define the key as
the ID of the array is that I have, in the past, needed different
amounts of information with regard to the data coming back. By using
the key/ID, I can keep all the data in 1 entry.
e.g.
Editing ...
name="data[{$a_Row['ID']}]['name']"
name="data[{$a_Row['ID']}]['date']"
name="data[{$a_Row['ID']}]['email']"
$_POST['data'][123] is the record containing 'name'=>'xxxx',
'date'=>'yyy', 'email'=>'zzz'
sort of thing.
name="data[{$a_Row['ID']}][delete]"
would have been a more appropriate in my usage.
Also, unless you've got a constant called 'id', the output wouldn't be correct.
echo '<input type="checkbox" name="delete[]" value="{$a_Row['ID']}" />';

Ok.
Now got it working with the following two bits of script:
if ($_POST['btnDel'] == "Multiple deletion")
{
// perform multiple delete first
foreach ($_POST as $formField)
checkField($formField);
} // end of delete button pressed
and above that (seems to only see function if located above the call to it):
function checkField($field)
{
$start = substr($field, 0, 5);
if ($start == "doDel")
{
$id = substr($field,5,strLen($field) - 5);
$sql = "delete from article where ID = " . $id . ";";
$result = mysql_query($sql);
} // end of if doDel in string
} // end of function
The checkboxes are generated with the following line of script/code:
echo "<input type='checkbox' name='doDel" . $row['id'] . "' value='doDel" .
$row['id'] . "' />";
I initially tried just using either strpos() or stripos() functions to check
if the substring doDel was there, but for some reason it never returned a
result of false no matter what was in the form field's value, so switched
over to the instance of substr() as above.
Will also just now add on some javascript to make the user confirm that they
do in fact want to delete selected records, but anyway...
Thanks for giving me the right ideas with regard to what route to follow,
and I'll just also say that obviously I need to carry on with this stuff a
bit since your examples mostly seemed a bit strange to me with regard to
just including variables etc. inside the string values to be used, which is
why I instead just used what I reckon is a simpler syntax as such.
Stay well

Eek!
echo "<input type='checkbox' name='doDel" . $row['id'] . "'
value='doDel" . $row['id'] . "' />";
really would be a lot easier on you if use ...
echo "<input type='checkbox' name='doDel[" . $row['id'] . "]'
value='doDel" . $row['id'] . "' />";
Now, $_POST['doDel'] is an array you can foreach() on without any need
to decode ...
foreach($_POST['doDel'] as $ID_to_delete => $value_associated_with_input) {
if (intval($ID_to_delete) > 0) {
// Now you can delete based upon the id held in $ID_to_delete.
}
}

If you want to take a look at the heredoc [1] and nowdoc [2]
documentation, you may find that these are a LOT easier to work with
than trying to quote ' and " appropriately.
e.g.
echo <<< END_INPUT
<input type="checkbox" name="doDel[{$row['id']}]' value="doDel{$row['id']}" />
END_INPUT;
for example.

Richard Quadling.

Ok, will try out that one.
Basically you're saying that the PHP backend will automatically make those
checkboxes into an array if I implement that syntax?
There is really only one other form field on that page - a search textbox -
apart from the possible 50 checkbox fields, but will definitely look into
it.

I kinda fail to see the use of this function on windows.
Anyone care to explain?
I see the use for IPC on non windows as you can fork there.
Is it just that you can easily create 2 sockets at the same time on
windows? As I read it they are connected with one another so thats not
really useful either.
Thanks!
