php - $_POST key name length? -

-

i experiencing odd behaviour. have following 2 <input type='image'> (with src attribute equal name attribute):

<input type='image' name='http://farm1.static.flickr.com/224/471627793_fbda6cecbe_s.jpg'> <input type='image' name='http://farm5.static.flickr.com/4053/4501238330_c5a85162ef_s.jpg'>

my question is: why first input submit , second 1 doesn't? using cakephp , if click on second image, $this->params['form'] empty. when click on first image, works fine: $this->params['form'] contains correct image name it's coordinates clicked.

this odd behaviour , believe can happen if $_post limit keys' length.

any highly appreciated! thank you!

php not limit field name length multipart/ or -urlencoded post requests.

but suhosin indeed have http://www.hardened-php.net/suhosin/configuration.html#suhosin.post.max_name_length default of 64. , second url indeed 64 characters long.

less likely, possible mod_security setup. spill error message rather truncating.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
