Laravel put array into selectbox
提问by kim larsen
I am facing some problems with my selectbox, where i will put all available categories into the
我的选择框遇到了一些问题，我会将所有可用的类别放入
In my controller i am using this snip:
在我的控制器中，我正在使用这个片段：
return View::make("stories.add")
->with("title","Indsend novelle")
->with("categories", Category::all());
In my view i am trying to put all categories into the selectbox with this:
在我看来，我正在尝试将所有类别放入选择框中：
{{Form::select("category", $categories)}}
I could make this, but that won't work, because Form::select has to be as an array?
我可以做到这一点，但这行不通，因为 Form::select 必须是一个数组？
@foreach ( $categories as $category )
{{$category->name}}
@endforeach
What to do?
该怎么办？
I have made this and it works, but it looks too ugly and not user-friendly, any suggestions?
我已经做了这个并且它有效，但它看起来太丑陋而且不用户友好，有什么建议吗？
$test = Category::all(); $myArray = array();
foreach ( $test as $o):
$myArray[] = $o->name;
endforeach;
return View::make("stories.add")
->with("title","Indsend novelle")
->with("categories", $myArray);
var_dump:
变量转储：
array(2) {
[0]=>
object(Category)#36 (5) {
["attributes"]=>
array(4) {
["id"]=>

Use it this way:
以这种方式使用它：
$categories = Category::pluck('name', 'id');
return View::make('....', compact('categories'));
And now in the view:
现在在视图中：
{{ Form::select('selectName', $categories, null); }}
Edit: Found in the docs Query builder # SelectHave a look to this

What you need to do is give Form::select()an array of category names and their ids. If you iterate over the categories, you can aggregate these and then pass them to Form::select().
您需要做的是提供Form::select()一组类别名称及其 ID。如果您遍历类别，则可以聚合这些类别，然后将它们传递给Form::select().
$categories = Categories::all();
$selectCategories = array();
foreach($categories as $category) {
$selectedCategories[$category->id] = $category->name;
}
return View::make("stories.add")
->with("title","Indsend novelle")
->with("categories", $selectCategories);

What you need to do is instead of using the with() function with the view put inside the controller function.
您需要做的是，不要将 with() 函数与放置在控制器函数中的视图一起使用。
$categories = Category::all();
After this you need properly reconstruct the array:
在此之后，您需要正确重建数组：
$category = array();
foreach($categories as $cat)
{
$category[]['id'] = $cat->attributes['id'];
$category[]['name'] = $cat->attributes['name'];
}
now in the View::make()
现在在 View::make()
return View::make("stories.add",array('title'=> "Indsend novelle","categories", $category));
I hope this can be of some help.
我希望这能有所帮助。

I like the approach suggested by Israel Ortu?o
我喜欢Israel Ortu?o建议的方法
I would only add a small modification, so that the select starts with an empty "Choose from the List"option by default.
我只会添加一个小的修改，以便默认情况下选择以空的“从列表中选择”选项开始。
$categories = array(0=>'Choose from the list') + Category::lists('name', 'id');
return View::make('....', compact('categories'));
Now the dropdown looks like this:
现在下拉菜单如下所示：
<option value="0">Choose from the list</option>
<option value="{whatever-the-category-id}">Category 1</option>
...
