append url for JSON array in laravel - php

Question

I have a JSON field in my MySQL table column which has an JSON array with part of images URLs.
"images": [
{
"images": {
"original": "/storage/uploads/1.png",
"300": "/storage/uploads/300.1.png",
"600": "/storage/uploads/600.1.png",
"900": "/storage/uploads/900.1.png"
},
"thumb": "/storage/uploads/300.1.png"
},
{
"images": {
"original": "/storage/uploads/2.png",
"300": "/storage/uploads/300.2.png",
"600": "/storage/uploads/600.2.png",
"900": "/storage/uploads/900.2.png"
},
"thumb": "/storage/uploads/300.2.png"
},
{},
]
I want to get the array with appending a Base URL for each of the values of the array.
"images": [
{
"images": {
"original": "http://localhost:8000/storage/uploads/1.png",
"300": "http://localhost:8000/storage/uploads/300.1.png",
"600": "http://localhost:8000/storage/uploads/600.1.png",
"900": "http://localhost:8000/storage/uploads/900.1.png"
},
"thumb": "http://localhost:8000/storage/uploads/300.1.png"
},
{
"images": {
"original": "http://localhost:8000/storage/uploads/2.png",
"300": "http://localhost:8000/storage/uploads/300.2.png",
"600": "http://localhost:8000/storage/uploads/600.2.png",
"900": "http://localhost:8000/storage/uploads/900.2.png"
},
"thumb": "http://localhost:8000/storage/uploads/300.2.png"
},
{},
]
I have tried with Collections function like below code. But was not succeeded.
'images' => collect($item->images)->map(function ($image) {
return url($image);
})->all(),

Answer 1

For collections you would need to create a collection of the second images keyed array as well. collect() does not create a recursive collection.
So if you had the following array:
$item = [
"images" => [
[
"images" => [
"original" => "/storage/uploads/1.png",
"300" => "/storage/uploads/300.1.png",
"600" => "/storage/uploads/600.1.png",
"900" => "/storage/uploads/900.1.png"
],
"thumb" => "/storage/uploads/300.1.png",
], [
"images" => [
"original" => "/storage/uploads/2.png",
"300" => "/storage/uploads/300.2.png",
"600" => "/storage/uploads/600.2.png",
"900" => "/storage/uploads/900.2.png",
],
"thumb" => "/storage/uploads/300.2.png",
]
]
];
and you really wanted to use collection, then the following would work:
$item = collect($item['images'])->map(function ($item) {
$images = collect($item['images'])->map(function ($item) {
return url($item);
});
return [
"images" => $images->toArray(),
"thumb" => url($item['thumb']),
];
});

Answer 2

You can use nested foreach to solve this
$json = json_decode($item->images, true); // I'm using true to convert the json to array
$images = [];
foreach ($json as $index => $array) {
foreach ($array as $key => $value) {
if (is_array($value)) {
foreach ($value as $path_key => $path) {
$images[$index][$key][$path_key] = url($value[$path_key]);
}
} else {
$images[$index][$key] = url($value);
}
}
}
If you dd($images); you will get
array:2 [▼
0 => array:2 [▼
"images" => array:4 [▼
"original" => "http://localhost:8000/storage/uploads/1.png"
300 => "http://localhost:8000/storage/uploads/300.1.png"
600 => "http://localhost:8000/storage/uploads/600.1.png"
900 => "http://localhost:8000/storage/uploads/900.1.png"
]
"thumb" => "http://localhost:8000/storage/uploads/300.1.png"
]
1 => array:2 [▼
"images" => array:4 [▼
"original" => "http://localhost:8000/storage/uploads/2.png"
300 => "http://localhost:8000/storage/uploads/300.2.png"
600 => "http://localhost:8000/storage/uploads/600.2.png"
900 => "http://localhost:8000/storage/uploads/900.2.png"
]
"thumb" => "http://localhost:8000/storage/uploads/300.2.png"
]
