Im trying to get a value from a specific key in my array. However, the key(name) exists at 2 levels, and this is not something I have control of.
I need to check the array for the value of key 'totalWeight' in a multidimensional array.
Im receiving the array and doing my check like this....
$json = file_get_contents('php://input');$body = json_decode($json, true);
if($body['eventName'] == 'shippingrates.fetch') {
$shippingWeight = $body['content']['totalWeight'];
// other logic code here...
}
The rest of the code works fine, the problem is that 'totalWeight' exists at 2 levels, and I need ONLY the first level (which is the total weight of the cart, not the individual items in the cart...)
The array I receive looks like this:
{"eventName": "shippingrates.fetch",
"mode": "Live",
"createdOn": "2014-11-11T23:47:00.6132556Z",
"content": {
"items": [
{
"totalWeight": 1000,
"customFields": [
{
"name": "Gift",
"operation": null,
"type": "checkbox",
"options": "true|false",
"required": false,
"value": "false"
}
],
"unitPrice": 180
},
{
"totalWeight": 1200,
"customFields": [
{
"name": "Gift",
"operation": null,
"type": "checkbox",
"options": "true|false",
"required": false,
"value": "false"
}
],
"unitPrice": 200
}
],
"totalWeight": 9600,
"customFields": [
{
"name": "I have read and accept the conditions of sale",
"operation": null,
"type": "checkbox",
"options": "true|false",
"required": true,
"value": "true"
}
],
"itemsCount": 5,
"metadata": null
}
}
This is how I'm checking....
if($shippingWeight > '3000') {$rate = $shippingRatesHigh;
} elseif($shippingWeight > '5000') {
$rate = $shippingRatesMax;
} else {
// default
$rate = $shippingRatesStd;
}
When I have multiple items in the cart, it bases the 'totalWeight' on one of the entries inside the ['items'] array, if only one product exists then my check works...
How can I get only that 'totalWeight' inside 'content' without it travelling further into the array inside 'items'.
Any help would be most appreciated!
Well for a start the json data you are receiving is an object i.e. its wrapped in {} and not an array which would be wrapped in [] so why force it into an array.
If you use this idea, I think its easier to visualize.
$json = file_get_contents('php://input');
$body = json_decode($json);
echo 'The total weight of all shipments is ' . $body->content->totalWeight;
If you then want to get an individual item weights or for example check that all the item weights are equal to the total weight, you could do
$sumOfItemRates = 0;
foreach( $body->content->items as $item) {
$sumOfItemRates += $item->totalWeight;
}
echo 'Sum Of Individual Items Weights is ' . $sumOfItemRates;
I always think that objects are easier and cleaner to code than arrays.
I tested that code, here is the full test run using PHP CLI:
<?php
$json = '{
"eventName": "shippingrates.fetch",
"mode": "Live",
"createdOn": "2014-11-11T23:47:00.6132556Z",
"content": {
"items": [
{
"totalWeight": 1000,
"customFields": [
{
"name": "Gift",
"operation": null,
"type": "checkbox",
"options": "true|false",
"required": false,
"value": "false"
}
],
"unitPrice": 180
},
{
"totalWeight": 1200,
"customFields": [
{
"name": "Gift",
"operation": null,
"type": "checkbox",
"options": "true|false",
"required": false,
"value": "false"
}
],
"unitPrice": 200
}
],
"totalWeight": 9600,
"customFields": [
{
"name": "I have read and accept the conditions of sale",
"operation": null,
"type": "checkbox",
"options": "true|false",
"required": true,
"value": "true"
}
],
"itemsCount": 5,
"metadata": null
}
}';
$body = json_decode($json);
echo 'The total weight of all shipments is ' . $body->content->totalWeight . PHP_EOL;
$sumOfItemRates = 0;
foreach( $body->content->items as $item) {
$sumOfItemRates += $item->totalWeight;
}
echo 'Sum Of Individual Items Weights is ' . $sumOfItemRates;
And the output was
The total weight of all shipments is 9600
Sum Of Individual Items Weights is 2200
Which I believe is what you were asking it to do.
