Laravel 5: Insert image urls into column as array - php

Question

I am building an application using Laravel 5 where I want to insert several image urls within an array separated by commas. This would be placed in a column on the database. The files are successfully uploaded to my AWS S3 bucket, but it's now the input to the database. I tried using Laravel's array_add helper but I get an error stating I am missing argument 2. I am wondering how would I be able to achieve this. My current alternate solution is to put the images with the post id and use the relationship to connect them together.
For reference: The column I intend to place the images is picgallery, and the insert is done using $newproperty['picgallery'] variable.
public function store(Request $request)
{
//establish random generated string for gallery_id
$rando = str_random(8);
//input all data to database
$data = $request->all();
$newproperty['title'] = $data['title'];
$newproperty['address'] = $data['address'];
$newproperty['city'] = $data['city'];
$newproperty['province'] = $data['province'];
$newproperty['contact_person'] = Auth::user()->id;
$newproperty['gallery_id'] = $rando;
$newproperty['property_description'] = $data['description'];
if($request->hasfile('images')) {
$files = $request->file('images');
//storage into AWS
foreach ($files as $file) {
$uploadedFile = $file;
$upFileName = time() . '.' . $uploadedFile->getClientOriginalName();
$filename = strtolower($upFileName);
$s3 = \Storage::disk('s3');
$filePath = 'properties/' . $rando . '/' . $filename;
$s3->put($filePath, file_get_contents($uploadedFile), 'public');
$propicurl = 'https://s3-ap-southeast-1.amazonaws.com/cebuproperties/' . $filePath;
$array = array_add(['img'=> '$propicurl']);
$newproperty['picgallery'] = $array;
}
}
Properties::create($newproperty);
return redirect('/properties');
}

array_add requires 3 parameters
$array = array_add($array, 'key', 'value');
(https://laravel.com/docs/5.1/helpers#method-array-add)
For example
$testArray = array('key1' => 'value1');
$testArray = array_add($testArray, 'key2', 'value2');
and you will get
[
"key1" => "value1",
"key2" => "value2",
]
You might not be able to use array_add in this case.
I think in order to fix your issue, fix your foreach loop to be something like this
//storage into AWS
// init the new array here
$array = [];
foreach ($files as $file) {
$uploadedFile = $file;
$upFileName = time() . '.' . $uploadedFile->getClientOriginalName();
$filename = strtolower($upFileName);
$s3 = \Storage::disk('s3');
$filePath = 'properties/' . $rando . '/' . $filename;
$s3->put($filePath, file_get_contents($uploadedFile), 'public');
$propicurl = 'https://s3-ap-southeast-1.amazonaws.com/cebuproperties/' . $filePath;
// change how to use array_add
array_push($array, array('img' => $propicurl));
// remove the below line
// $array = array_add($array, 'img', $propicurl);
}
// move this assignment out of foreach loop
$newproperty['picgallery'] = $array;
