Laravel 5 : Setting limitations on uploaded files without changing php.ini?

I learned it is required to modify the values in php.ini in order to set the limitation for uploading files. However, I'm in a situation where I can't touch php.ini.

Let me explain the problem briefly.

<input type="file" name="thumbnail" accept="image/*">

I'm trying to get the thumbnail and get it in a controller.

if($this->request->hasFile('thumbnail')){
    $file = $this->request->file('thumbnail');
    //Other tasks
}

If the file size is over a certain point, I'd like to prevent it and show a warning. However, apparently, if the uploaded file is over the limit, request->hasFile() returns false even though it's actually true. (I saw that by dd())

It's probably impossible to catch this type of error by hasFile(), since it simply doesn't catch it.

Any advice would be appreciated.

Use validation rule max

$validator = Validator::make($request->all(), [
    ...
    'thumbnail' => 'max:30000', // kilobytes
    ...
]);

Fist of all, make sure that your form uses multipart/form-data enctype.

<form action="/upload-image" method="post" enctype="multipart/form-data">
    <input type="file" name="thumbnail" accept="image/*">
    <input type="submit">
</form>

To get the file size you can use getClientSize() function of UploadedFile object.

So to limit the size and show a warning, you can do something like that:

if ($this->request->file('thumbnail')->getClientSize() > 5){
    return redirect()->back()->withErrors(['thumbnail', 'File is too big. Limit is 5MB.']);
}

Then in the view print the error.

Have you checked the validation rules?

Validating Files

Rule:

size:value

The field under validation must have a size matching the given value. For string data, value corresponds to the number of characters. For numeric data, value corresponds to a given integer value. For files, size corresponds to the file size in kilobytes.
