@Pappnase++:
would it be possible that yu chnage the script this way we can place it into the frontend_init folder? so there is no change of the source needed.
Sure - the most functions are duplicate then but easyer for update etc...
---
I will post the code here (asap)!

He we are...
Code: Select all

/** ---------------------------------------------------------------------------
*
* -=[ Extended {RANDOM} ]=-
*
* gently extented the CORE::{RANDOM}-RT to the possibility to
* create an RANDOM-Value only one times per interval -
* the random-image will now show the whole interval
*
* @4phpwcms 1.2.6DEV (and before?- not testet yet!)

* @version 0.4-DEV
* @see CORE::front.func.inc.php for original {RANDOM}
*
* @example generic {XRANDOM:[path]:[interval]}
* - [path] = search here for images
* - [interval] - using the old value
* interval >0 => interval in minutes
* interval =0 => like the core RT - new image on every call
* @example live {XRANDOM:picture/my_random_images:1440}
* This shows your random images which you have placed in a subfolder
* called "my_random_images" within the folder "picture" with an
* intervall of 1440 min = 24 hours.

* v0.4 - build 4 frontend_render, rename to XRANDOM
