Defining arrays and using them in content/template/snippets

bolle

Hello, wan't sure which forum tags to use for this question, but here it is.
How do I define arrays, and later how do I use arrays in content, or in snippets?

For example, I want to define an array in /shared/data.txt, something like this:
fruits:
apple: green
banana: yellow
cherry: red

Then, in the snippet I want to call elements of this array, for example
@{ fruits.apple } or @{ fruits["apple"] }

How would I go about this?

bolle Hi, that’s a pretty good question. At the moment it is only possible to you use plain PHP for arrays.

Assuming you have in your data.txt a fruits variable like:

fruits: apple, banana, lemon

Then you can use it like this in a PHP snippet in a separate snippets/fruits.php file:

$Page = $Automad->Context->get();
$array = Parse::csv($Page->get('fruits'));
foreach ($array as $item) {
    echo $item;
}

You can use that snippet then like this in your template:

<@ snippets/fruits.php @>

If you need an associative array you can put this into your data file:

fruits: {"apple": "green", "banana": "yello"}

And in your snippet file:

$Page = $Automad->Context->get();
$array = json_decode($Page->get('fruits'));
foreach ($array as $key => $value) {
    ...
}

All the examples are untested though. But maybe it can help you to make it work.

mad it worked. Not 100% the way you described, but it worked 🙂

Simple array, in '/shared/data.txt' should look like this: (brackets are must)
fruits1: [applee, bananaa, lemonn]
Snippet 'snippets/fruits.php' should look like this:
$Page = $Automad->Context->get(); $arrayz = $Page->get('fruitz');

Associative array, and second snippet you provided look correct.

bolle if I put array in page.txt (not /shared/data.txt) - how would I call it from the snippet?
Similar to $Page = $Automad->Context->get(); ?

Figured it out. I guess 🙂

First, json arrays must use quotes ("), for example:
cars: ["Ford", "BMW", "Fiat"]
Then, from the snippet, I can call that array with:
$Page = $Automad->Context->get(); $array = json_decode($Page->data['cars']);
or
$Page = $Automad->Context->get(); $array = json_decode($Page->get('cars'));

bolle You can actually just use a comma separated string as array:

$array = Parse::csv($Page->get('fruits'));

To get shared data, use this:

$array = $Automad->Shared->get('fruits'));
