I'm trying to check this checkbox:

<input type="checkbox" id="tandcs" name="tandcs"> 

(BTW: 'tandcs' stands for 'Terms And Conditions')

This seems to pose a problem because it has no defined value. The WWW::Mechanize::tick() documentation has this to say about the value attribute: 'Dies if there is no named check box for that value.' which is probably the reason why using 'undef' for the value doesnt work...

Using this:

$mech->tick('tandcs' => undef); 

resulted in the following error:

No checkbox "tandcs" for value "" in form at ...

Is there a 'magic' way of getting this infernal checkbox ticked?

Not sure if "ticking" a valueless checkbox makes any sense for non-Javascript purposes, but you probably need it ;-) I had to add some Javascript generated hidden inputs once, that drove me crazy too. After some searching, I found an interesting thread where Gisle explains a little about the undocumented push_input method of HTML::Form.

I think I am using this in the tests of CPAN::Forum but as I can see I have not pushed it to the repository yet so I cannot show the real code. It looks more or less like this:

my $form = $w->form(....);
my $input = $form->find_input('tandcs');
$input->check;

Thank you, szaz, for the speedy and useful response. For what its worth, in case anyone else ever has this error, here is how I was originally going to do it, and the fix I had to use to get around it... ORIGINAL PLAN:

$mech->field('pass1', $password);
$mech->field('pass2', $password);
$mech->tick('tandcs');
$mech->click_button( 'value' => 'Sign up!' );

Which would have been rather simple and elegant, had it worked. Unfortunately, a web developer neglected to add a value for a checkbox, and WWW::Mechanize relies upon the value being there, hence this forum post, and the following workaround...

$mech->field('pass1', $password);
$mech->field('pass2', $password);
my $form = $mech->current_form();
$form->find_input('tandcs')->check();
$mech->click_button( 'value' => 'Sign up!' );
