如何在Laravel中插入字符串作为查询?我必须处理"书籍格式的动态价值" (例如" pdf"," epub"," physical","")这些格式用逗号分隔。这是我的代码:

$formats_sql = '';
$format_filter_count = 0;
$format_filter = explode(',', $format_filter);
foreach ($format_filter as $format_filter_tmp) {
    if ($format_filter_count == 0) {
        $formats_sql .= "where('format', '=', '{$format_filter_tmp}')";
    } else {
        $formats_sql .= "->orWhere('format', '=', '{$format_filter_tmp}')";
    }
    $format_filter_count += 1;
}

if ($price_filter == 'paid') {
    $books = Book::where('book_id', '=', $category_book->book_id)->$formats_sql->where('sell_price', '>', '0')->where('status', '=', '1')->get();
}

但是提出了这个问题:

Undefined property: Illuminate\Database\Eloquent\Builder::$where('format', '=', 'pdf')->orWhere('format', '=', 'epub')

你过于复杂了。您应该使用whereIn来搜索值数组。

您可以将上面的整个代码浓缩为:

if ($price_filter == 'paid') {
    $formats = explode(',', $format_filter);
    Book::where('book_id', $category_book->book_id)->whereIn('format', $formats)->where('sell_price', '>', '0')->where('status', '1')->get();
}
