Daily Images

Hello modx community. I am looking for some help.

I have a bunch of pages that have TV's that have URL's to live pictures (snowmobile trail webcam's). I am trying to create a "daily" webcam photo on the homepage but I am not sure how to approach or even code something like this. Does anyone have suggestions on how to go about this? I was initially thinking of trying to use getResources.

Any help would be much appreciated. Thanks.

Probably the most efficient thing would be a custom snippet that checks the day of the week and returns the appropriate link or image -- something like this.

Bob do you think it would be helpful to hook a MODX snippet up to a Cron job for this?

I don't see any advantage to that (a cron job). The first user to visit the page on a given day will see the new image, no?

Maybe there's something I'm missing.

True. Simple snippet no harm in calling uncached I suppose

BobRay,

Thanks for the snippet. Is there a way to randomly select these image TV's from resources with your snippet? I have more than 7 images and with the snippet that you wrote for me below would only allow for 7 images to be displayed and each of those images would be displayed the same day of each week.

Is there a way I can use getResources in the snippet below. I could then code the getResources snippet to randomly select an image each day of the week. Just a suggestion. Thank you again for your help.

<!--?php
$dayOfWeek = date('w');  // 0 - 6, 0 is Sunday

switch($dayOfWeek) {
    case 0:
       $output = $something
       break;
    case 1:
       $output = $somethingElse
       break;

    // etc.

}

return $output;

-->

That gets trickier. Pulling a random image for each page visit is easy, but if you want to randomly assign images to days and make sure that you don't have the same image for different days, it gets more complicated.

You'd also have to decide how often you want to re-assign the images (if ever).


This might be a good job for MIGx.

Can you tell us a bit more about that?

and perhaps also about this.

Currently I have a parent resource (webpage) that is called web cam network. Under the parent webpage there are 17 child resources (webpages) that have a Template Variable assigned to those pages. Each page has a different URL to an image on the web. These images are of others webcams that people have shared with me and they are allowing me to post their image on my website. These images are not on my webserver they are a picture from a web camera that has a URL. These images are continually updated throughout the day.

On my homepage I would like to randomly choose one of the 17 webpages that have this template variable and display the image of this template variable on my homepage. I would then like for the image to change every day to a different image.

I hope this helps answer your questions. If you have more, please let me know.

Thank you.

wouldn't this be an option:
Put all urls into a MIGX - TV with this fields:
url,date,active..... and what you need else

use this logic:

1. is there an active item for the current date?
yes -> goto 7

no ->
2. empty all dates and active-states which are older than today
3. are there more than 7 urls which have empty dates
no -> goto 6

yes -> get a random list of all this urls (with an empty date)
4. search for the latest date
5. replace all empty dates of the random list with coming dates (later than the latest date found or later than today) and save the result as json-records back to the MIGX-TV

6. set the item with the current date to active
7. display the active item with the current date
