Get Repeater Fields from other pages

[Kay Lohn]

Hi,

Can someone please help me with the scenario below, I am trying to build a Project portfolio sort of a site.

I have a homepage which displays three recent items from a Repeater field named my_items (3 RepeaterReady fields are created for the home page and filled with data), example code below:

<?php foreach ($page->my_items as $item) { ?>

    // display item values, for example:
 
      <div class="item">
      <img src="<?php echo $item->my_image->url; ?>" />
      <a href="<?php echo $item->my_link->name; ?>">View</a>
      </div>

<?php }; ?>

I have a page called my-items with repeater 'my_items' field for displaying the same as above.

The page 'my-items' has children, each of which have 'my_items' Repeater field for displaying data respective to that page using the same code as above.

The page/ site hierarchy is like:

Home - uses Repeater 'my_items'

   |- My Items  - uses Repeater 'my_items'

       |- Item 1  - uses Repeater 'my_items'

       |- Item 2  - uses Repeater 'my_items'

       |- Item 3  - uses Repeater 'my_items'

       |- ...

   |- My Items 2

       |- Item 1  - uses Repeater 'my_items'

       |- Item 2  - uses Repeater 'my_items'

       |- Item 3  - uses Repeater 'my_items'

       |- ...       

and so on.

What I am doing as a starter with PW is:

- Entering same data for in Repeater for Home for some item, lets call this 'A'.

- Entering the same for My Items the data for 'A'

- Entering the same for Item 1 the data for 'A'

Therefore, I am adding 'A' thrice in three places, violating the DRY principle.

What I have tried and failed is:

- To get 'A' to display in My Items page fetched from Item 1 and then,

- the Home to display 'A' fetched from My Items so that I only enter data for 'A' in Item 1 and not in every page that displays it.

Caveats:

- The homepage displays 3 recent only from page My Items

- Page My Items displays one from each children

- Item 1 has multiple Repeater blocks/ pages for displaying data (e.g. My Item #1, My Item #2, My Item #3 .......... My Item #n)

Another way I think to explain it would be a photography site with structure as:

Home - display 3 recent photo projects

    |- Projects - displays each child project with the 1st photo and its description

        |- Nature - Has many photos with description

        |- Animals - Has many photos with description

        |- People - Has many photos with description

I hope I had explained properly. Any help or suggestion would be highly appreciated.

don't have much time, but does this help:

<?php foreach ($page->my_items as $item) { ?>
    
    <div class="item">
    	<img src="<?php echo $item->my_image->url ?>" />
  		<a href="<?php echo $item->my_link->name ?>">View</a>
    </div>

<?php } ?>

UPDATE:

For the Home page I managed to get 3 unsorted results displayed from the Projects page (I am following the example of a photography project website as in my previous post):

<?php
    $projects = $pages->get('/projects/')->my_items->getArray();
    foreach ($projects as $key => $project) { 
	?>
    <div class="item">
        <img src="<?php echo $project->my_image->url; ?>" />
        <a href="<?php echo $project->my_link->name; ?>">View</a>
    </div>
        
    <?php 
	if ($key == 2) {
        break;}
    };   
?>

- How do I sort $projects array by date?

   -The 'Projects' should be recent three.

- How do I limit get/ array?

   - If there be 1000 projects, the code would unnecessarily get an array of 1000 items whereas it only needs three items from the Projects page.

- Is there a better way to do this?

Any help would be highly appreciated. Thanks.

No. This doesn't work. Sorry, I omitted the PHP open/ close tags in my original post. The code is there for reference only. Thanks for the pointer, I'll add the tags to the Original post to avoid confusion.
