I have form field like this:
<input class="form-control js-invoice-product-search" placeholder="Product" autocomplete="off" type="text" name="data[products[0][name]]">
As you can see, field name is 'data[products[0][name]]'.
But then I submit the form, i get result like this:
["products[0"]=>
array(3) {
["name"]=>
string(4) "test"
It looses bracket: "products[0" So if i have more than one product, i get 3 different elements with different names, instead of array.
Well, It was ridiculously simple solution. A bit shame, that I didn't tried it.
Instead name "array[key1[nestedone]]" you just need to use 'array[key1][nested1]'.
HTML is not PHP. :)
