سؤال

The php file is in web site directory (/var/www) and I would like to execute it from index.html which is in the same directory.

The php file:

    <?php
    exec("sudo -u pi /home/pi/camcv/camcv .. ");
    ?>

Can be run by typing php /var/www/script.php in command line from anywhere in the system, it executes properly (camera flashes, opens the window with picture, no errors). I would need it to be executable by www-data user from website.

I know there are many options, I have tried submit forms, onClick actions, sending a parameter ( $_POST['xy']) then watching it with "if" structure in php file, AJAX in form of XMLHttpRequest and in form of $.ajax , I tried to include javascript jquery.min.js and have tried to add permissions in sudoers or changed ownership of folders/files with allowing to read/write/execute... all without achieving the goal.

So my questions are:

-Does someone have a bulletproof way to make this work ?

-Can you tell me what exactly do I have to add in sudoers ?

Thanks for any advice.

PS: Few of the tries did redirect me to page http://(ip)/script.php so there is at least some response from the buttons. Also, XMLHttpRequest did work on Changing the text on webpage (reading and posting txt file).

PSS: The function does not require any return information, I would need the page to stay on the site with the button, possibly not reloading.

try to resolve this problem with jQuery:

<!doctype html><head><meta charset="utf-8"></head><body>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>
$(function(){
$("#clickme").bind('click', function(){
        $.get( "script.php", function( data ) {
        $( ".result" ).append( data );
        });
    });
});
</script>
<input type="submit" id="clickme" value="TEST">
<div class="result">Result...</div>
</body>
</html>

if your "script.php" has any response you will get it in the div container
