Issue with repeating an option in a select list

Posted on 2016-08-03

I have a select list that is populated by the result in a query.
For example:
The result is 'Car'
so 'Car' is shown in the select menu. Thats fine.
Problem is I'd also like to show the other choices ie: Truck, SUV, Minivan etc. in case they made a mistake and need to select a different one.

So doing that is simple enough, as I loop through the possible choices after the select list is populated with the user's choice ie: 'Wagon'.

Where its a bit 'off' is because I loop through all the choices, I show 'Wagon' again in the list. Ideally I'd just want to have 'Wagon' in the list as the 'selected' choice and not repeat it.

Any idea how that is done?

Here is the image of what is going on (may help)
sample select
Code I'm using is:

<select  class="select" id="category_id" name="category_id">
@if(!isset($vehicle->category_name))
<option>Choose type...</option>
@else
<option  value="{{ $vehicle->category_name }}"> {{ $vehicle->category_name }}</option>
@endif

@foreach ($vehicle_types as $vehicle_type)
<option  value="{{ $vehicle_type->category_title }}"> {{ $vehicle_type->category_title }}</option>
@endforeach
</select>

Not tested logic behind code is to check whether category_name matches  with category_title if yes than go selected

<select  class="select" id="category_id" name="category_id">
@if(!isset($vehicle->category_name))
<option>Choose type...</option>
@endif

@foreach ($vehicle_types as $vehicle_type)
<option  value="{{ $vehicle_type->category_title }}" @if($vehicle->category_name == $vehicle_type->category_title) selected="selected" @endif  > {{ $vehicle_type->category_title }}</option>
@endforeach
</select>

Conceptually, it seems like this might be a useful idea, but I don't know what the data structures and names look like, so I can't verify that it would be workable.  The idea is that if "wagon" is selected, then we would remove "wagon" from the array that is used to build the option tags.
<select  class="select" id="category_id" name="category_id">
@if(!isset($vehicle->category_name))
<option>Choose type...</option>
@else

<option  value="{{ $vehicle->category_name }}"> {{ $vehicle->category_name }} selected </option>
@unset($vehicle_types->$vehicle->category_name) // SOMETHING LIKE THIS, MAYBE?

@endif

@foreach ($vehicle_types as $vehicle_type)
<option  value="{{ $vehicle_type->category_title }}"> {{ $vehicle_type->category_title }}</option>
@endforeach
</select>

Yes that did the trick. Tried both and the unset had no effect on removing the repeat as Ray suspected. Thanks!
