[Mojolicious] Get an array from checkboxes

[mab974]

Hi,

How do I get multiple checkbox values as an array?
I always get the value of the last checked checkbox.


my example :
in template

%= check_box 'groupMemberships' => $groupname

or when checked

<input type='checkbox' name='groupMemberships' checked value='<%=
$groupname %>'>

and in controller

my @groups = $c->param('groupMemberships');

Thanks in advance.

param returns a single value, by design, because this avoids the context sensitivity bug that led to for example  https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-1572. To get multiple values, use every_param, which returns an array reference:

  my $groups = $c->every_param('groupMemberships');

Thanks Dan !

It seems I get only the NEW checked values not all checked values.
Do I use it the right way ?

my @members = @{$c->every_param('groupMembers')};

That is correct, it should return all "values" of checked items with that "name". I don't know what the distinction of "new checked values" is that you mention. Make sure the checkboxes are all within the same form tag.

^^ Also, if you’re not sure whether the problem is in Perl or in the browser, you can use this to see what data the browser intends to send prior to sending.
