PHP slideshow refresh

[smathis]

I’m new to php and attempting to set up a simple php gallery, where the next and prev buttons count up and down through an array then issue a page refresh when pushed.

I know I can do this with js, but I’m wanting just a regular php fallback if js isn’t loaded. For some reason, I cannot get this to work! I can display the array images, links, etc, I just can’t find a good reference to get the regular ole form buttons to call a refresh within a function. Any ideas how I can fix this? Thanks in advance!!

$i = 0;

if($i > 6){

$i = 0;

}

if($i < 0){

$i = 6;

}

//Next Function

function next_funct($i) {

if($_POST) {

++$i;

echo "";

}}



//Prev Function

function prev_funct ($i) {

if($_POST) {

--$i;

echo "";

}}



$current_page = $_SERVER;



?>

The way I see it, you’re echoing a function (prev_funct and next_funct) when you click on of the buttons (onclick).
I don’t think it’s needed or possible to echo a function, and it therefore should just read onclick=”“

Same goes for next_funct ofcourse.
Not sure, but this might be it.

Gave it a try, and it didn’t change the output any.

Would I need to load the meta refresh differently? I was reading somewhere that you couldn’t offer a refresh except at the head of the document? Is that correct? I’ve read some really conflicting information on this concept so I’m a bit at a loss.

What does it output anyway at the moment when you click those buttons?
