I want to fetch the data from children field or get count of children.
I am fetching like this: $temp = json_decode($request->get('tempData');
Here is my json payload:
tempData:[{
"id":"c625",
"name":"Chapter 1",
"children":[
{
"id":3,
"type":"study material",
"content":"Demo Study Material Title 2"
},
{
"id":4,
"type":"study material",
"content":"Demo Study Material Title 3"
},
{
"id":5,
"type":"study material",
"content":"Demo Study Material Title 4"
}
],
"type":"chapter"
}
]
You can get children count for all items on tempData array by using collection
collect(json_decode($request->get('tempData'), true))
->mapWithKeys(fn($item) => [$item['id'] => count($item['children'])])
->all();
to get result of children count for every id:
[
"c625" => 3
]
You could create a new array and push children in that array with a foreach loop.
$temp = json_decode($request->get('tempData');
$children = array();
$child_count = 0;
foreach ($temp['children'] as $child) {
$child_count++;
array_push($children, $child);
}
