Hey all,
I have something weird happening here. In a module I have developed, I have a Form posting a series of checkboxes to $_POST as an array.. ie:

$r .= $DSP->input_checkbox("groups[]", $row['id'] , $selected ).NBS.$row['cat_name'];

as you can see the checkboxes are posting as an array
The output $POST array contains the groups array pefectly like this:

groups[] => array([0]=>123, [1]=>456, [2]=>789)


thats perfect, but for some reason it is also appending , and auto-incrementing it seems, separate values at the end of the $_POST array like so:

[groups_0]=>123 [groups_1]=>456 [groups_2]=> 789

which is weird.

The function is fairly simple, so i wont post it here, ive looked at the 3 lines very closely and no, theres nothing that could be adding to $POST like that.

Im wondering if its a bug or maybe something that is supposed to happen when using $DSP->input_checkbox?

try taking the period off the front of NBS and see what that does.

Vinci,

I know you didn’t want to post the whole function but can you do that anyway?

A few months on an ANOTHER module, and I am getting the same issue.

Simple form data, to post into an array within $_POST.
I have say, a very simple form:

<input type="text" name="1[this]" value="xx"/>
<input type="text" name="1[that]" value="yy"/>

$_POST on the processing page will look like:

[1] => array([this] => xx, [that] => yy), [1_this] => xx, [1_that] => yy


Those last two variables SHOULDNT be there,

Does anyone think this could be a server issue (im using MAMP), such as an apache module messing with $_POST? or heaven forbid missed EE setting.. or worst case, EE bug?

EE always does that, don’t know why.

If you have:
<input name=“cat[]” value=“bla”>
<input name=“cat[]” value=“foo”>
<input name=“cat[]” value=“owyeah”>

Your $_POST array will be:

array(
cat => array('bla','foo','owyeah'),
cat_1 => 'bla',
cat_2 => 'foo',
cat_3 => 'owyeah'
)

If i am mistaken that this is an EE “feature” please correct me.

Feature? its annoying as I will have to do quite a few preg_match’s on the $keys of the array to remove them!

is there an ‘off’ button anywhere?

No need for regex,

foreach ($_POST as $key => $value)
{
    if (is_numeric(substr($key, 0, 1)) === TRUE)
    {
        unset $_POST[$key];
    }

}


This code beats regex in speed.
