clear as mud?


i guess not.
here is what i ended up with
i took the insert code and placed it in the header section of theme.html
then i went to just before that code still in theme.html
and pasted the other part of the code.

This is the way it layed out exactly
<img src="<{php}> echo getRndImgURL('headimages'); <{/php}>" alt="" width="730" height="150" /><br />
                <img src="<{php}> echo getRndImgURL('headimages'); <{/php}>" alt="" width="730" height="150" />

but for some reason
when i goto my page
i see the header but NO images in it
i just see the box or table the header is supposed to sit in

nothing else on the page shows below the header
its all blank with its background color showing

Re: random image in header? possable or no?

i completely get more confused with each answer on this
and its not you mboyden
forgive me
im really good at HTML and some PHP

but for some reason i am completely NOT getting this at all so hear me out

i need to place this
<img src="<{php}> echo getRndImgURL('random'); <{/php}>" alt="" width="158" height="116" />


in my header at the location where i want the images to show up

the folder where the images are located is called
RANDOM

the location of this folder is right now inside a specific theme folder
"geometric_red"

Now just before the code above i post pasted, i need to place this code

<{php}>
function getRndImgURL($path) { // Display Random Image from File Path
    $i = 0;
    $dir = @opendir(XOOPS_ROOT_PATH.'/themes/random/'.$GLOBALS['xoopsConfig']['theme_set'].'/'.$path);
    while ( false !== ($filename = readdir($dir)) ) {
        if ( preg_match("/(.gif|.jpg|.png)$/", $filename) ) { // image filter
            $images[$i] = $filename;
            $i++;
        }
    }
    closedir($dir);
    mt_srand( (double)microtime() * 1000000 );
    $choice = array_rand($images);
    return XOOPS_URL.'/themes/random/'.$GLOBALS['xoopsConfig']['theme_set'].'/'.$path.'/'.$images[$choice];
}
<{/php}>



is this correct?
please see where the $dir is specified in the second code here.

Was i supposed to change it to match? or not.

Im looking at the code you pasted just now but im just no getting it
i have a code very similar to it and it works on another site ( not XOOPS ) that i administer for someone else.
its works and calls exactly the same way

create a subdirectory called " random "
in "random " place an index.php file with the code in it.
goto the page where you want to rotate images
call "index.php" using an "image source" function




the problem i am having doing that is
i cant for the life of me get my "theme.html" to call am image source in the header of this file

To make it less confusing take url images in stead of random.
<img src="<{php}> echo getRndImgURL('images'); <{/php}>" alt="" width="158" height="116" />

Create a directory /themes/random/geometric_red/images/ (for you: /themes/random/yourthemename/images/)and place there the images to be picked.

Go back to my original code (without the </div> tag). Do not edit the original function - leave it exactly as is. This function when called allows you to pass the name of the subdirectory of images. What that does is allows you to have more than one set of randomly called images on your page. Each subdirectory will need to have the same size images for this to work, though.

The way this is designed, it is THEME-based (the assumption being that if you change themes you likely want to change images).

So, in your theme directory (in your case, geometric_red -- I've used this theme myself), make a subdirectory for your images (in your case, 'random', thus XOOPS_ROOT/themes/geometric_red/random). Place your images (all same size) in this subdirectory.

Then, make the call passing the name of the subdirectory in the call like this:

<img src="<{php}> echo getRndImgURL('random'); <{/php}>" alt="" width="158" height="116" />

Notice that when calling the function, we pass the subdirectory path (inside the theme) of the images. Note, too, that if you have more than one set, you could pass a path, for instance if you have:
random/set1
random/set2
random/set3...
then the subdirectory passed when calling the function would be 'random/set1', 'random/set2', etc.

BTW, make sure you set the width and height to be the size of your pictures. The numbers used in the example I provided were for the particular placement I used.

Hopefully I've diluted those muddy waters some?
