Re: [PHP] How to pass unknown number of variables to a function?
Thank's for the help everybody!
I used something different (a little like this nice one from Terence (thank
you!) but with JS:
I named my form 'test' and included a hidden field 'collector'.
At the checkboxes the name is the value I need. The box, when checked, gets
the value 1.
In the boxtags I added:
onclick=add_values($name)
where name is the value I want.
Then I wrote this little script:
$js = script type=text/javascript
function add_values(val) {
document.test.'collector'.value += val;
document.test.'collector'.value += \,\;
}
/script;
It produces a comma separated list in the field 'collector' whith only the
checked values.
When sending the form, only this field is transmitted. This is just what I
wanted and it works fine.

This is a nice easy one :)
It couldn't be simpler.
Just put empty square brackets (as used in arrays) in front of your
checkbox name.
The example below assumes you have PHP 4.1 or greater (which uses
$_POST to contain form posted data)
notice how name=ck[]
html
head
titleUntitled/title
/head
body
?php
if(count($_POST)) {
foreach ($_POST[ck] as $varval) {
print(div.$varval./div);
}
}
?
form action=test.php method=post
input type=checkbox name=ck[] value=val1br
input type=checkbox name=ck[] value=val2br
input type=checkbox name=ck[] value=val3br
input type=checkbox name=ck[] value=val4br
input type=checkbox name=ck[] value=val5br
input type=submit
/form
/body
/html
in earlier versions of PHP, $_POST[ck] would be equal to $ck
(although, the former is safer)

Hi everybody on this rainy morning!
My problem:
I give the user a form with a list of options with checkboxes.
The list is long and not predictable - the values change always.
I want to put the checked values (or all, that doesn't matter) in an
array,
to pass it to my function.
How can I write those keys and values in an array?
I suppose it will be best done with JS - but since I don't know JS ...
Has anybody a ready solution?
Thank's a lot!

Suppose you have a number of checkboxes. First, you name them
sequentially (like active_0,active_1 and so on) and you assign it your
value. Then you process posted data like this. BEWARE! you need at least
an array of hidden variables to know exactly how many checkboxes you
must process. Then you just rebuild it the structure and pass it thru.
# put the received input into an ordered structure
##
$count = 0;
while ( isset($id[$count]) ) {
# Build variable names;
###
$w_active = active_.$count;
# get actual form values
$active[$count] = $$w_active;
$count++;
}
Hope it solves the problem. I've been using this for ages and it never
gave me problems.

Hi Uwe,
If you define the checkbox list as an array (OptionList[] in the example
below), only the checked values will be returned as an array $OptionList
when you post the form. You can then use this as an array or pass it as an
array to a function in the script:
?
$i = 0;
while (isset($OptionList[$i])) {
echo You have chosen option .$OptionList[$i].br;
$i++;
}
?
