How to use nested array in email template

Question

I have a nested array that I am passing as templateVar.

setTemplateVars(['details' => $arr])

The array($arr) is

[0] => [
 ["key1"]=>value1
 ["key2]=>value2
]
[1]=>[
 ["key1"]=>value1
 ["key2]=>value2
]
.
.
.
All arrays have same keys.

I have tried both updates mentioned in How to show array in email template file?

In the template file, I'm trying to use it as -

<?php foreach($details as $detail) : ?>
 <p>{{trans ' %val' val=$detail.key1}}</p>
 <?php endforeach; ?>

I cannot pass it as a string as the array can be an array of 100s of arrays with same keys.

• fmsthird: you can use foreach loop
• Dhaduk Mitesh: Have you did it?

Providing you an static way to get the specific value of array key. You can pass it like this:

setTemplateVars(['details' => $arr[0]->key1]) //get key1 value from array 0
setTemplateVars(['details' => $arr[1]->key1]) //get key1 value from array 1

Using foreach loop

(削除) foreach($arr as $detail){ setTemplateVars(['details'=> $detail["key1"]);} (削除ここまで)

<?php foreach($details as $detail) : ?>
 <p>{{trans ' %val' val = $detail["key1"]}}</p>
<?php endforeach; ?>

• coderGeek: Can you elaborate how to use foreach? I've tried - foreach($details as detail): <p>$detail.key1</p> - This doesn't work
• fmsthird: check updated ans
• coderGeek: How to use this is the template file?
• fmsthird: can you update your question with your code in the template file
• fmsthird: can you try this <?php foreach($details as $detail) : ?> <p>{{trans ' %val' val = $detail["key1"]}}</p> <?php endforeach; ?>
