?>
<form action="https://www.paypal.com/fr/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_s-xclick">
    <input type="hidden" name="encrypted" value="<?php echo $data?>"/>
    <input type="submit" value="Commander" class="input_button">
</form>

I don't know why it's doesn't working on windows , but it's working on 1and1 (linux ?)

Thanks a lot cordially

Answer 1

i found a solution this night . In fact, solution is to use PHP to crypt SSL paypal button without command openssl. Paypal gives an example to use it : https://cms.paypal.com/fr/cgi-bin/?cmd=_render-content&content_ID=developer/library_download_sdks#WPST and download the Website Payments Standard toolkit.

thanks a lot see you soon
