我在一個問題上遇到了麻煩。在側邊欄過濾器功能中，當我單擊復選框時，它將正確顯示列表。但是當我取消選中復選框時，它將顯示“array_merge(): Argument #2 is not an array”檢查元素時顯示此錯誤。當我點擊復選框時，它會生成這個 url "http://abc.local/genre-tags/?id%5B%5D=31" 。當我取消選中復選框時，它會顯示錯誤的 url“http://abc.local/genre-tags/”。以下是控制器和js代碼。public function genresFilter () { $sortBy = Input::get('sortBy', 'id'); $dir = Input::get('direction', 'desc'); $orderBy = [ 'tracks'=>[ 'order_by'=>$sortBy, 'direction'=>$dir ] ]; $id = Input::get('id'); $category = Category::where('slug','music-genre')->first(); $tag = Tag::with('tracks','elements')->where('category_id', $category->id)->whereIn('id', $id)->get(); echo "<pre>"; print_r($tag->toArray()); die(); $this->layout->content = View::make('public.tags.genres', compact('tag')); }//Sidebar Filter Genre Tracks$(document).ready(function () { $('.genreTag').on('change', function (e) { $('input.filter-playlist, .popularGenreTag, .mood-emotion, .production-type, .vocals, .all-tracks, .last-year, .last-month, .last-week, .last-day').each(function() { var $this = $(this); $this.prop('checked', false); $this.parent().find('> div').removeClass('chk-checked').addClass('chk-unchecked'); }); e.preventDefault(); id = []; $('.genreTag:checked').each(function() { id.push($(this).attr('id')); });

我認為你的控制器有問題：你有 whereIn 查詢需要在第二個參數上傳遞數組。但是你的 id 是空的，為什么它會給出這樣的錯誤。嘗試將代碼更改為以下將起作用。
public function genresFilter ()
{
$sortBy = Input::get('sortBy', 'id');
$dir = Input::get('direction', 'desc');
$orderBy = [
'tracks'=>[ 'order_by'=>$sortBy, 'direction'=>$dir ]
];
$id = Input::get('id');
// check if id is not array, then give empty array
if(!is_array($id)) $id = [];
$category = Category::where('slug','music-genre')->first();
$tag = Tag::with('tracks','elements')->where('category_id', $category->id)->whereIn('id', $id)->get();
echo "<pre>";
print_r($tag->toArray());
die();
$this->layout->content = View::make('public.tags.genres', compact('tag'));
}
解決方案 2
public function genresFilter ()
{
$sortBy = Input::get('sortBy', 'id');
$dir = Input::get('direction', 'desc');
$orderBy = [
'tracks'=>[ 'order_by'=>$sortBy, 'direction'=>$dir ]
];
$id = Input::get('id');
$category = Category::where('slug','music-genre')->first();
$tag = Tag::with('tracks','elements')->where('category_id', $category->id);
// if id is not null and and array then we do filter
if($id != null && is_array($id)) {
$tag->whereIn('id', $id);
}
$tag->get();
echo "<pre>";
print_r($tag->toArray());
die();
$this->layout->content = View::make('public.tags.genres', compact('tag'));
}
