How can I do this...?

How can I do this:

Let's say the user selects "Checkbox #1" and "Checkbox #3" in the form below and submit, the values will be passed as "01" and "03", right? How can I do for these values "01" and "03" passed by the form to recognize it's respective local vars shown below to do the sum and print it's values and labels on screen?

I know how to do it with only one value but not with an array. Please help.

HTML Code:

<input name="checkboxes[]" type="checkbox" value="01">Checkbox #1<br>
<input name="checkboxes[]" type="checkbox" value="02">Checkbox #2<br>
<input name="checkboxes[]" type="checkbox" value="03">Checkbox #3<br>
<input name="Submit" type="submit" value="Submit">
</form>

</body></html>

PHP:

// get_checked.php

$checkbox_label_01 = "Book";
$checkbox_price_01 = "5.00";

$checkbox_label_02 = "CD";
$checkbox_price_02 = "8.00";

$checkbox_label_03 = "Games";
$checkbox_price_03 = "5.00";

$count_checked = count($checkboxes);

for ($i=0; $i<$count_checked; $i++) {
echo $checkboxes[$i];

}

why are they in an array? if they aren't in an array you can just do this:

add checkbox 1 to checkbox 2..

jackiw

They're in an array because I have more then 100 checkboxes in the form and I don't want to name them like check_01, check_02... and so on... and have to verify which one of them like

if(check_01) {
do this and that
}

if(check_02) {
do this and that
}

and so on...

Do you have a better idea?

well, honestly, i can't see how u'll ever get it to work.. i don't know what it's returning exactly.. :S i've never tried putting arrays inside checkboxes even when there was alot of them.

does each checkbox have it's own array number? example:
checkbox 1 = array[1]
checkbox 2 = array[2]
?

jackiw

Yes, each one has its own array number but I don't know the number till the user selects the checkbox and I do the count to check how many have been selected.

$count_checked = count($checkboxes);

for ($i=0; $i<$count_checked; $i++) {
echo $checkboxes[$i];

}

i don't know j/s all that well, but i know it assigns the array of checkboxes before the user selects it.. but that's not very helpful for you. i'm going home from work now lol bi!
