Question

Ok this is probably really simple and I just can not figure it out! I need to grab the value from an array in foreach loop in php and pass it into an array fro jquery. Here is my code:

foreach ($results as &$value) {
            $vall[] = $value.", ";
        }   
        $result = count($results);
        echo $result;
        print_r($vall);

This prints out a normal array = Array ( [0] => one.jpg, [1] => two.jpg, [2] => three.JPG, [3] => four.JPG, )

I need it to create an array like this: one.jpg, two.jpg, three.JPG, four.JPG (only the values) Then I need to pass that to my jquery:

$(".next").click(function(){
            var p = [<?php echo $vall ?>];
            var start = id;
            var next = p[($.inArray(start, p) + 1) % p.length];
            var prev = p[($.inArray(start, p) - 1 + p.length) % p.length];
            $(".cont").append(next);
            $(".cont").append(prev);
            });

**I also need to take the comma off of last value.. any help or alternatives to get this done would be greatly appreciated.

Answer 1

Why not take the far simpler route and use json_encode()?

Replace this…

[<?php echo $vall ?>]

with this….

<?php echo json_encode($results); ?>

and you can get rid of your entire foreach loop.
