Insert Multiple Rows in Laravel (Image Upload Issues) - laravel-8

Question

In my application, I have faced several issues when I try to insert multiple rows of data into a database in laravel 8. Basically this issues is related to image upload. I have add related code to get help.
Controller View:
foreach($request->param_img as $key => $param_img){
$data = new PortfolioParam;
$data->param_desc = $request->param_desc[$key];
if($request->hasfile('param_img')){
$file = $request->file('param_img');
$extension = $file->getClientOriginalExtension();
$filename = time().'.'.$extension;
$file->move('upload/portfolio_param/', $filename);
$portfolio->param_img = $filename;
}
$data->portfolio_id = $portfolio->id;
$data->save();
}
Blade View:
<td class="pl-0 border-0">
<textarea class="form-control" name="param_desc[]" id="" cols="30" rows="3"></textarea>
</td>
<td class="border-0">
<input type="file" class="form-control" name="param_img[]">
</td>
Error
Call to a member function getClientOriginalExtension() on array
How can I get rid of this problems??

Answer 1

You have looped through the image but you have not used it in your image uploading code. You are still using the request data. Check this out, hopefully it helps.
// $file = $request->file('param_img');
$file = $param_img;
$extension = $file->getClientOriginalExtension();
$filename = time().'.'.$extension;
$file->move('upload/portfolio_param/', $filename);
$portfolio->param_img = $filename;
