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.

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.
}
}
