dropdown show right value - php

Question

ve two values in my combo box. Car and bicycle when the user selects one of them it will be stored in the database with 1 or 2. But how do I make sure that when the user edits it the chosen values shows up.
For example I've saved bicycle in the database than when the user wants to edit it it must show bicycle and not car!
I'm working with laravel.
EDIT
<div class="form-group">
<label for="content" class="col-lg-2 control-label">Standaard route</label>
<div class="col-lg-10">
#if($standaardroute->isEmpty())
<label>U heeft nog geen standaardroutes. Maak deze hier aan.</label>
#else
<select class="form-control input-sm" name="standaardroute" id="standaardroute">
#foreach($standaardroute as $route)
<option value="{!! $route->id !!}">{!! $route->van !!} - {!! $route->naar !!}</option>
#endforeach
</select>
</div>
</div>
#endif
EDIT
I've 2 dropdown menus. When one dropdown is selected the other one should receive a number from the database and show the right value for example bicycle. When the first dropdown menu is selected it post a request and receives the values back. When I receive information back for a text box I say:
$("#van").val(result.van);
But how do I have to do this with a dropdown menu?
<script>
$(document).ready(function () {
var xhr;
});
$("#standaardroute").change(function(e) {
csrf = $("#token").attr('content')
option = $(this).val();
$.ajax({
url: '/public/receiveuserinformation',
type: 'POST',
data: { option_id: option },
beforeSend: function(xhr){xhr.setRequestHeader('X-CSRF-TOKEN', csrf);},
success: function(result) {
$("#van").val(result.van);
//here should be something for the dropdownmenu
}
});
});
</script>

Suppose you've two options in an array: $types = array('1' => 'car', '2' => 'bicycle'); and you're saving it in products table and you've current product data in $product variable
<select>
<?php foreach($types as $type_id => type_name): ?>
<option value="<?php echo $type_id; ?>" <?php if($type_id == $product->type) echo "selected"; ?>>
<?php echo $type_name; ?>
</option>
<?php endforeach; ?>
</select>
EDIT: if you're using blade in laravel then you could simply achieve it by doing this:
{!! Form::label('type', 'Type: ') !!}
{!! Form::select('type', $types !!}
EDIT2: Try this:
<option value="{!! $route->id !!}" {{ ($standaardroute->route == $route->id) ? 'selected':'' }}>{!! $route->van !!} - {!! $route->naar !!}</option>
Note: replace $standaardroute->route your actual variable
EDIT3: Put this inside your success function:
$('#van option').each(function(){
$(this).removeAttr('selected');
if($(this).val() == result.van){
$(this).attr('selected', 'selected');
}
});
Note: I've not tested this
