Iterating POST data with PHP gives me stupid results - php

Question

So I have this multi-dimensional $_POST array in PHP:
Array
(
[addonGroupName] => Testname
[addons] => Array
(
[1534766970prkszomwvb] => Array
(
['title'] => Addon Title
['products'] => Array
(
[0] => Array
(
['code'] => 1
['title'] => test product
['price'] =>
['active'] => on
)
)
)
)
)
Strangely I cant seem to access the value parts of the array, see what I mean:
if(count($_POST['addons']) != 0)
{
foreach($_POST['addons'] as $key => $addon)
{
echo $key;
//prints 1534766970prkszomwvb
print_r($addon);
// prints
Array
(
['title'] => beta
['products'] => Array
(
[0] => Array
(
['code'] =>
['title'] =>
['deliveryPrice'] =>
['pickupPrice'] =>
['active'] => on
)
)
)
echo $addon['title'];
// prints ""
}
}
Now I'm not new to programming but this has me pulling my hair out for a solid 2 hours now.
Is there something that I am missing or is there a limitation to the depth and accessibility of multi-dimensional arrays?

Answer 1

If this is the array:
Array
(
[addonGroupName] => Testname
[addons] => Array
(
[1534766970prkszomwvb] => Array
(
['title'] => Addon Title
['products'] => Array
(
[0] => Array
(
['code'] => 1
['title'] => test product
['price'] =>
['active'] => on
)
)
)
)
)
then the code you used:
foreach($_POST['addons'] as $key => $addon)
{
print_r($addon);
Should actually output:
[1534766970prkszomwvb] => Array
(
['title'] => Addon Title
['products'] => Array
(
[0] => Array
(
['code'] => 1
['title'] => test product
['price'] =>
['active'] => on
)
)
)
Which means there is another array in between: 1534766970prkszomwvb
foreach($_POST['addons'] as $key => $addon){
foreach($addon as $sub){
print_r($sub); // should give you the output in question.
echo $sub["title"]; // Addon Title
}
}
If you want to output the products array you can use array_column to get the products array and loop that (if there is more than one item).
You can use array_column to get the "products" array.
$products = array_column($_POST, "products");
foreach($products as $prod){
echo $prod["title"]; //test product
echo $prod["code"]; //1
}
