Laravel: showing selected value in edit form - php

Question

I added a drop down list in the user registration form in Laravel. Now I want to make a form to edit it but I'm stuck.
What I did is I made a drop down list which a new user can register where he/she lives. I used a list of cities(pref.php) in the configuration folder to make this drop down list. I want the user to be able to see the cities that they have registered default when opening the edit form and then change it or leave it alone but I couldn't figure out how to do this.
Here are my codes.
editprofile.php
<form action="/profile" method="post" enctype="multipart/form-data">
{{ csrf_field() }}
{{ method_field('patch') }}
<p>
<label><b>name</b><br>
<input type="text" name="name" value='{{ $user->name }}'><br>
</label>
</p>
<p>
<label><b>location</b><br>
<select type="text" name="location" value="{{ $user->prefName }}">
#foreach(config('pref') as $key => $score)
<option value="{{ $key }}">{{ $score }}</option>
#endforeach
</select>
</label>
</p>
<p>
<label><b>mail adress</b><br>
<input type="text" name="email" value='{{ $user->email }}'><br>
</label>
</p>
<p>
<label><b>profile image</b><br>
<input type="file" name="profile_image"><br>
</label>
</p>
<input type="hidden" name="id" value="{{ $user->id }}">
<input type='submit' value='edit' class="btn btn-primary mt-3">
</form>
ProfileController.php
public function edit()
{
$user = Auth::user();
return view('profile.editprofile', ['user' => $user]);
}
public function update(ProfileRequest $request, User $user)
{
$user = User::find($request->id);
$user->name = $request->name;
$user->email = $request->email;
$user->location = $request->location;
if ($request->hasFile('profile_image')) {
Storage::delete('public/profile_image/' . $user->profile_image);
$path = $request->file('profile_image')->store('public/profile_image');
$user->profile_image = basename($path);
}
$user->update();
return redirect('/profile');
}
pref.php
<?php
return array(
'0' => 'not selected',
'1' => 'New York',
'2' => 'Los Angeles',
'3' => 'Dallas'
);
I thought this page had a similar problem but it was a little different.
Any help would be appreciated as I have tried multiple methods with no success.
Thank you in advance.

Answer 1

to make an option selected you have to put selected property in that option. putting value on select won't work. you can do it like
<select type="text" name="location">
#foreach(config('pref') as $key => $score)
<option value="{{ $key }}" {{ $user->location == $key ? 'selected' : '' }}>{{ $score }}</option>
#endforeach
</select>

Answer 2

In your edit form you had a particular user information by it ID in one array after that you get the user into a edit page right, using that array you can check with option box like below example
<select type="text" name="location" value="{{ $user->prefName }}">
#foreach(config('pref') as $key => $score)
<option <?php echo($get_array_by_user_id->table's_exist_location_value == $key) ? 'selected' : ''; ?> value="{{ $key }}">{{ $score }}</option>
#endforeach
</select>
I think it is working exactly to you : - )
Thank You,
