how to add an item to array in laravel - php

Question

i have a function that it fills the one array like below :
if (isset($options[$attribute->id][$optionId])) {
foreach ($options[$attribute->id][$optionId] as $item) {
. . . .
$attributeOptionsData[] = [
'id' => $optionId,
'label' => $attributeOption->label ? $attributeOption->label : $attributeOption->admin_name,
'swatch_value' => $attribute->swatch_type == 'image' ? $attributeOption->swatch_value_url : $attributeOption->swatch_value,
'products' => $options[$attribute->id][$optionId],
'images' => $productImage ?? null,
];
dd($attributeOptionsData);
}
the result of this dd is like below :
array:1 [▼
0 => array:5 [▼
"id" => 1
"label" => "black"
"swatch_value" => "#000000"
"products" => array:1 [▶]
"images" => "product/4618/rAkC2aC3QJB6kMiAAzIGk6nUzGHxpdfIS55g3T0P.jpeg"
]
]
now what i want to do is that after the last line add some content to this array and make it like below:
array:1 [▼
0 => array:5 [▼
"id" => 1
"label" => "مشکی"
"swatch_value" => "#000000"
"products" => array:1 [▶]
"images" => "product/4618/rAkC2aC3QJB6kMiAAzIGk6nUzGHxpdfIS55g3T0P.jpeg"
"custom_field" => "some value"
]
]
on the line that i dd the array i want add the customfield to it . how can i do that thanks in advance.
the reason i dont insert like others in that i want to add the custom field in a foreach loop based on 1 field of that array

Answer 1

So, if you simply want to add something at the bottom of an array, just use array_push().
In your case, you would need to retrieve the whole $attributeOptionsData[] in a foreach loop and append the array to the key you're in, during that loop. Be aware that this is somehow inefficient. If you want to add a line based on a value you can retrieve in the first foreach loop, you could've just made an if-statement asking for that value and add it with array_push() afterwards.
Either way, I think this is what you're looking for:
if (isset($options[$attribute->id][$optionId])) {
foreach ($options[$attribute->id][$optionId] as $item) {
$attributeOptionsData[] = [
'id' => $optionId,
'label' => $attributeOption->label ? $attributeOption->label : $attributeOption->admin_name,
'swatch_value' => $attribute->swatch_type == 'image' ? $attributeOption->swatch_value_url : $attributeOption->swatch_value,
'products' => $options[$attribute->id][$optionId],
'images' => $productImage ?? null,
];
}
foreach($attributeOptionsData as $key=>$data){
array_push($attributeOptionsData[$key], ["custom_field" => "some value"])
}
}

$attributeOptionsData is an associative array. You can assign values to it by specifying the array $key:
$attributeOptionsData[$key] = $value;
