Pushing object to nested JSON using PHP? - php

Question

In the following JSON object, I have two dummy products and a nested group of reviews that are siblings to one another:
product.json
[
{
"name": "Dodecahedron",
"price": 2.95,
"description": "This gem is awesome and has 10 sides.",
"images": [
{
"full": "dodecahedron-01-full.jpg",
"thumb": "dodecahedron-01-thumb.jpg"
}
],
"reviews": [
{
"stars": 5,
"body": "I love this product!",
"author": "joe#thomas.com"
},
{
"stars": 1,
"body": "This product sucks",
"author": "tim#hater.com"
}
]
},
{
"name": "Hectahedron",
"price": 8.95,
"description": "Wonderful 6-sided gem that will please all.",
"images": [
{
"full": "hectahedron-01-full.jpg",
"thumb": "hectahedron-01-thumb.jpg"
}
],
"reviews": [
{
"stars": 4,
"body": "product is awesome, seriously!",
"author": "james#crazy.com"
},
{
"stars": 2,
"body": "Seriously sucks, would give 0 if i could",
"author": "john#hater.com"
}
]
}
]
I am using AngularJS to send the newly created JS review object from an HTML form to PHP. But how in PHP do you push this review data to become a sibling IN "reviews" AND target the exact product it should be in? I'm very new to PHP and would greatly appreciate your guidance!

Answer 1

If I understand what you are asking, here you need to use the json_decode() function:
$productsRreviews = json_decode($_POST['reviews'], true);
This will give you a PHP associative array that you can process to do whatever you need to do. For instance:
foreach ($productsReviews as $productReviews) {
$name = $productReviews['name'];
$price = $productReviews['price'];
$reviews = $productReviews['reviews'];
foreach ($reviews as $review) {
$stars = $review['stars'];
...
}
}
Hope that helps!
