一页中的 Laravel 多分页

2022-01-04 00:00:00 php laravel pagination

我的分页出了点问题.我有两个包含来自数据库的数据的表，我使用 laravel 分页器对它进行了分页.

I'm having some trouble with my pagination. I'm having two tables with data from a database and I paginated it with laravel Paginator.

现在我的问题是，例如，当您转到第 2 页时，它会添加 ?page=2 但这会使第一个表格也转到第 2 页.

Now my problem is when you go to, for example, page 2 it adds ?page=2 but that makes the first table go to page 2 too.

反正有这样的东西吗?

page_table1={number}&page_table2={number}

因此您不会将页面更改应用于其他表格.

so you don't apply the page change on other tables.

推荐答案

很遗憾我现在无法测试此代码，只能浏览文档和代码(在 Illuminate/Pagination/Environment) 我猜你可能是这样的:

Unfortunately I can't test this code right now, but browsing at the docs and the code (in Illuminate/Pagination/Environment) I guess you could something like this:

# use default 'page' for this
$collection1 = Model::paginate(20);

# use custom 'other_page' for this
$collection2 = Model2::paginate(20);
$collection2->setPageName('other_page');

setPageName() 方法未在文档中记录，但它是与文档中指出的方法一起的公共方法，因此它应该可以正常工作.供参考，这是声明(vendor/laravel/framework/src/Illuminate/Pagination/Environment.php 中的 l. 171-180):

The setPageName() method isn't documented in the docs, but it's a public method alongside those indicated in the documentation, so it should be working fine. FOr reference, this is the declaration (l. 171-180 in vendor/laravel/framework/src/Illuminate/Pagination/Environment.php):

/**
 * Set the input page parameter name used by the paginator.
 *
 * @param  string  $pageName
 * @return void
 */
public function setPageName($pageName)
{
    $this->pageName = $pageName;
}

现在考虑到您将有另一个查询字符串附加到 url，因此您需要告诉分页考虑它.使用 appends() 方法:

Now take into consideration that you will have another query string appended to the url, so you need to tell the pagination to consider it. Use the appends() method:

$collection1->appends(array_except(Request::query(), 'page'))->links();

$collection2->appends(array_except(Request::query(), 'other_page'))->links();

也就是说，告诉每个 Presenter 用所有查询字符串(由 Request::query() 产生的数组没有使用的当前索引来构建 url分页器，否则你最终会得到一个双倍值).array_except() 是一个 Laravel 内置的数组助手，它返回给定数组(第一个参数)清除了传递的索引(第二个参数).

That is, tell each Presenter to build up the url with all the query strings (the array resulting from Request::query() without the current index used by the paginator, or you'll end up with a double value). array_except() is a Laravel built in array helper that returns the given array (1st parameter) purged of the passed index (2nd parameter).

我会尽快尝试测试此代码，但它应该可以工作.无论如何请告诉我！

I'll try to test this code as soon as I can, but it should work. Let me know in any case!
