Can anyone help me, how to show image the right way in edit.blade.php

Answer 1

For this line of your code please change as follow:
From:
<img src="{{ $post->image_thumb_url ? $post->image_thumb_url : 'http://placehold.it/200x150&text=no+image' }}" alt="...">
To:
<img src="{{ $post->imageThumb ?? 'http://placehold.it/200x150&text=no+image' }}" alt="...">
Then add the following function to your Post model:
public function imageThumb(){
if($this->image_thumb_url){
if(File::exists(public_path() . '/imgberita/'.$this->image_thumb_url)){
return public_path() . '/imgberita/'.$this->image_thumb_url;
}
}
return null;
}
Then use the function in your view like this if that image exist it will return the location if not exist it will return the null.
$post->imageThumb
If you get issue with this function just update the public_path() . '/imgberita/' inside the function, hope you get idea.
For textare you can use the old() function in your view:
<textarea rows="5" cols="5" class="form-control" name="body" value="{{$post->body}}"></textarea>
For example like this:
<textarea rows="5" cols="5" class="form-control" name="body" value="{{old('body') ?? ''}}"></textarea>
But remember we use the old('body') function when we use the validate() and we pass the data from controller by using ->withInput() like this:
return redirect()
->back()
->withInput()
->withErrors($validator);
Also you can directly pass data in your edit.blade.php by using with($request) function.
If your body is null you will get error then use the {{$post->body ?? ''}}.

Change this
<img src="{{ $post->image_thumb_url ? $post->image_thumb_url : 'http://placehold.it/200x150&text=no+image' }}" alt="...">
to
<img src="{{ $post->image_thumb_url ? asset('/imgberita/'.$post->image_thumb_url) : 'http://placehold.it/200x150&text=no+image' }}" alt="...">
OR
<img src="{{ $post->image_thumb_url ? asset('public/imgberita/'.$post->image_thumb_url) : 'http://placehold.it/200x150&text=no+image' }}" alt="...">
