Wordpress - how detect if current page is the login page
提问by mems
There is a better way than using global variable $pagenowto detect current page if is login page, like a is_admin()?
$pagenow如果是登录页面，则有比使用全局变量检测当前页面更好的方法，例如is_admin()?
if ($pagenow != 'wp-login.php' && !is_admin())
{
// Do something
}
There is a global variable $current_screenwith a getter get_current_screen()(which declared in /wp-admin/includes/template.php), but it's always equal to NULL
有一个$current_screen带有 getter的全局变量get_current_screen()（在 中声明/wp-admin/includes/template.php），但它始终等于NULL
On #15686 (Detect the current page template tag) – WordPress Tracit's sayed it's usually used $pagenow, but I think is not the good way to compare non-dynamic pages against there file name instead of there function (like admin page)
在#15686（检测当前页面模板标签） – WordPress Trac据说它通常被使用$pagenow，但我认为这不是将非动态页面与文件名而不是功能（如管理页面）进行比较的好方法

While I tend to agree with others on the need for a function is_login_page() or something similar, I found what seems to be the best answer at https://wordpress.stackexchange.com/questions/12863/check-if-were-on-the-wp-login-page, which I used to make the following:
虽然我倾向于同意其他人需要函数 is_login_page() 或类似的东西，但我在https://wordpress.stackexchange.com/questions/12863/check-if-were-找到了似乎是最好的答案on-the-wp-login-page，我用来做以下事情：
<?php
function is_login_page() {
return in_array($GLOBALS['pagenow'], array('wp-login.php', 'wp-register.php'));
}

If you are like me, and you actually tried to de-register / mess with the jQuery that WordPress automatically loads, then the correct answer is:
如果您像我一样，并且实际上尝试取消注册/弄乱 WordPress 自动加载的 jQuery，那么正确答案是：
Don'tuse wp_print_stylesto register your scripts – use wp_enqueue_scriptsinstead!
不要使用wp_print_styles注册脚本-使用wp_enqueue_scripts，而不是！
This hook will run onlyon the frontend, noton the login page, so there's no need for workarounds.
这个钩子只会在前端运行，而不是在登录页面上运行，所以不需要解决方法。

Can't you explain what are you going to do with it? So I can tell if you should code using wordpress hooks.
你不能解释一下你打算用它做什么吗？所以我可以告诉你是否应该使用 wordpress hooks 进行编码。
or you can use the absolute uri, just match it with wp-login.php
或者您可以使用绝对uri，只需将其与 wp-login.php 匹配即可
<?php
$uri = $_SERVER['REQUEST_URI'];
echo $uri;
?>
?>

Incase you want to be as non WP independant as possible; for instance in a plugin keeping future changes out of scope. You can use something like this:
如果您想尽可能不独立于 WP；例如在一个插件中，使未来的更改超出范围。你可以使用这样的东西：
function is_login_page() {
return !strncmp($_SERVER['REQUEST_URI'], '/wp-login.php', strlen('/wp-login.php'));
}
