How to update image using controller in laravel? - php

Question

I want to update user image but it's not getting updated. I have used following controller for updating the image.. Can you suggest what's the mistake in controller function?
View part :
<div class="form-group">
<label>Image Upload</label>
<input type="file" name="image" id="image"><img src="{{ asset('public/images/' . $course->image) }}" width="200px"/></br>
</div>
Controller function :
public function update(Request $request, $id)
{
$data=Course::findOrFail($id);
if ($request->hasFile('image'))
{
$file = $request->file('image');
$timestamp = str_replace([' ', ':'], '-', Carbon::now()->toDateTimeString());
$name = $timestamp. '-' .$file->getClientOriginalName();
$data->image = $name;
$file->move(public_path().'/images/', $name);
}
$data->course_code = $request['course_code'];
$data->course_title = $request['course_title'];
$data->course_credit = $request['course_credit'];
$data->save();
return redirect('course');
}

Answer 1

Did you checked file permission on 'images' directory? It needs to have write permission for uploading files.

Answer 2

The problem is this,
$data->image = $name;
You set the value but you don't save it anywhere. You must add a saving line.
$data->save();
Note that, calling update() only saves what you pass in as parameters, doesn't save what you set through the mutators.

Answer 3

See The mistake/ solution of the problem is first i need to store the update value and then save the new image. So I made some changes in controller and solved it..
Here is controller code:
public function update(Request $request, $id)
{
$data=Course::findOrFail($id);
$data->update($request->all());
if ($request->hasFile('image'))
{
$file = $request->file('image');
$timestamp = str_replace([' ', ':'], '-', Carbon::now()->toDateTimeString());
$name = $timestamp. '-' .$file->getClientOriginalName();
$data->image = $name;
$file->move(public_path().'/images/', $name);
$data->save();
}
return redirect('course');
}
