Get URL parameters inside custom module
提问by zied123456
I've created a custom block like this:
我创建了一个这样的自定义块：
class HelloBlock extends BlockBase implements BlockPluginInterface{
/**
* {@inheritdoc}
*/
public function build() {
$config = $this->getConfiguration();
$result = db_query('SELECT * FROM {test}');
return array(
'#theme' => 'world',
'#test' => $result
);
}
}
And I now want to programmatically get some parameter from the URL.
我现在想以编程方式从 URL 获取一些参数。
For example:
例如：
If the URL is http://localhost/drup/hello/5569I want to get hold of the value 5569inside my module.
如果 URL 是http://localhost/drup/hello/5569我想获取5569我的模块中的值。
I have tried arg(1)and drupal_get_query_parameters()but I got this error messages:
我试过了arg(1)，drupal_get_query_parameters()但我收到了以下错误消息：
Call to undefined function `Drupal\hello\Plugin\Block\arg()`
and
和
Call to undefined function `Drupal\hello\Plugin\Block\drupal_get_query_parameters()`
How can I get the parameters?
如何获取参数？

Use \Drupal\Core\Routing;:
使用\Drupal\Core\Routing;：
$parameters = \Drupal::routeMatch()->getParameters();
The named parameters are available as
命名参数可用作
$value = \Drupal::routeMatch()->getParameter('slug_name_from_route');
Where 'slug_name_from_router' comes from your routing.yml path property
'slug_name_from_router' 来自你的 routing.yml 路径属性的地方
path: '/your/path/{slug_name_from_route}'
路径：'/你的/路径/{slug_name_from_route}'
If you want the raw parameter without any upcastingyou can get
如果你想要没有任何向上转换的原始参数，你可以得到
$value = \Drupal::routeMatch()->getRawParameter('slug_name_from_route');

I used to get the parameter value from URL (localhost/check/myform?mob=89886665)
我曾经从 URL (localhost/check/myform?mob=89886665) 获取参数值
$param = \Drupal::request()->query->all();
And applied in my select Query
并应用于我的选择查询
$query = \Drupal::database()->select('profile_register', 'p1');
$query->fields('p1');
$query->condition('p1.mobileno', $edituseprof);
$query->condition('publishstatus', 'no');
$result = $query->execute()->fetchAll();
But on multiple parameter value, i am now successful(Ex:http://10.163.14.41/multisite/check/myform?mob=89886665&id=1)
但是在多个参数值上，我现在成功了（例如：http : //10.163.14.41/multisite/check/myform?mob=89886665&id=1 ）
$query = \Drupal::database()->select('profile_register', 'p1');
$query->fields('p1');
$query->condition('p1.mobileno', $edituseprof['mob']);
$query->condition('p1.ids', $edituseprof['id']);
$query->condition('publishstatus', 'no');
$result = $query->execute()->fetchAll();

arg() is deprecated in drupal 8, however we can get values like arg() function does in drupal 7 & 6
arg() 在 drupal 8 中被弃用，但是我们可以得到像 arg() 函数在 drupal 7 & 6 中所做的值
$path = \Drupal::request()->getpathInfo();
$arg = explode('/',$path);
print_r($arg); exit();
The output would be parameters in url except basepath or (baseurl),
输出将是 url 中的参数，除了 basepath 或 (baseurl)，
Array
(
[0] =>
[1] => node
[2] => add
)

$route_match = \Drupal::service('current_route_match');
$abc = $route_match->getParameter('node'); //node is refrence to what you have written in you routing file i.e:
in something.routing.yml
entity.node.somepath:
path: '/some/{node}/path'
I have used {node} as arg(1). And I can access it by using *->getParameter('node');
我使用 {node} 作为 arg(1)。我可以使用 *->getParameter('node'); 访问它。
Hope this will work.
希望这会奏效。

To get query parameter form the url, you can us the following. If you have the url for example,
要从 url 获取查询参数，您可以使用以下方法。例如，如果您有网址，
domainname.com/page?uid=123&num=452
To get "uid"from the url, use..
要从url获取“uid”，请使用..
$uid = \Drupal::request()->query->get('uid');
To get "num"from the url, use..
要从url 中获取“num”，请使用..
$num = \Drupal::request()->query->get('num');

If your url is like this below example
如果您的网址如下例所示
http://localhost/drupal/node/6666
Then you have to get the full url path by
然后你必须得到完整的 url 路径
$current_path = \Drupal::request()->getPathInfo();
then explode the path to get the arguments array.
然后分解路径以获取参数数组。
$path_args = explode('/', $current_path);
Another example if value passed by a key in url like below where id contains the value
另一个示例，如果值通过 url 中的键传递，如下所示，其中 id 包含值
http://localhost/drupal?id=123
You can get the id by given drupal request
您可以通过给定的 drupal 请求获取 ID
$id = \Drupal::request()->query->get('id');

Here's the example of accessing URL parameters and passing them to a TWIG template, I am considering you have already created your module and required files and suppose "/test?fn=admin" is your URL
这是访问 URL 参数并将它们传递给 TWIG 模板的示例，我认为您已经创建了模块和所需文件，并假设“/test?fn=admin”是您的 URL
In Your .module file implement hook_theme and define variables and template name (Make sure you replace "_" with "-" when creating the template file)
function my_module_theme () { return [ 'your_template_name' => [ 'variables' => [ 'first_name' => NULL, ], ]; }
在您的 .module 文件中实现 hook_theme 并定义变量和模板名称（确保在创建模板文件时将“_”替换为“-”）
function my_module_theme () { return [ 'your_template_name' => [ 'variables' => [ 'first_name' => NULL, ], ]; }
Now create your controller and put below code in it.
现在创建您的控制器并将以下代码放入其中。
namespace Drupal\my_module\Controller;
use Drupal\Core\Controller\ControllerBase;
use Symfony\Component\HttpFoundation\Request;
class MyModule extends ControllerBase {
public function content(Request $request) {
return [
'#theme' => 'my_template',
'#first_name' => $request->query->get('fn'), //This is because the parameters are in $_GET, if you are accessing from $_POST then use "request" instead "query"
];
}
}
Now in your TWIG file which should be "my-template.html.twig" you can access this parameter as,
现在在应该是“my-template.html.twig”的 TWIG 文件中，您可以访问此参数，
<h3>First Name: {{ first_name }}</h3>
And its done. Hope this helps.
它完成了。希望这可以帮助。

The Drupal docs are great on this: https://www.drupal.org/docs/8/api/routing-system/parameters-in-routes
Drupal 文档在这方面很棒：https: //www.drupal.org/docs/8/api/routing-system/parameters-in-routes
define your path variable in yaml
example.name: path: '/example/{name}' ...Add the variable in your method and use it
<?php class ExampleController { // ... public function content($name) { // Name is a string value. // Do something with $name. } } ?>
在 yaml 中定义路径变量
example.name: path: '/example/{name}' ...在您的方法中添加变量并使用它
<?php class ExampleController { // ... public function content($name) { // Name is a string value. // Do something with $name. } } ?>
