[英]How to check if url is the homepage
Found this answer If url is the homepage (/ or index.php) do this which was really helpful however doesn't fully answer my question. 找到了这个答案如果url是主页(/或index.php),这确实很有帮助,但是并不能完全回答我的问题。
I have an index of site for school that shows all my folders to different assignments. 我有一个学校网站索引,其中显示了我所有文件夹的不同任务。 so my homepage is actually domain/folder/index.html
所以我的主页实际上是domain / folder / index.html
so when I ask if $currentpage == /midterm/index.php || 所以当我问$ currentpage == /midterm/index.php ||时 /midterm/ it always triggers as true even if I am on /midterm/add.php
/ midterm /即使我在/midterm/add.php上,它也总是触发为true
<?php
$homeurl = '/midterm/index.php';
$homepage = '/midterm';
$currentpage = $_SERVER['REQUEST_URI'];
if ($currentpage == $homeurl || $homepage) {
echo '<div class="hero"></div>';
}
Your problem is in your conditional: if ($currentpage == $homeurl || $homepage)
will always return true
because you are stating that $currentpage
must equal $homeurl
, OR just simply $homepage
. 您的问题
if ($currentpage == $homeurl || $homepage)
条件: if ($currentpage == $homeurl || $homepage)
将始终返回true
因为您声明$currentpage
必须等于$homeurl
, 或者只是$homepage
。 Adding brackets helps showcase this: 添加括号可以帮助展示这一点:
if ( ($currentpage == $homeurl) || ($homepage) )
Because $homepage
is set, it's truthy
, and evaluates to true
. 因为
$homepage
已设置,所以它是truthy
,并且评估为true
。 Because only one part of the conditional needs to be true
due to your OR
( ||
), the condition returns true
as a whole. 由于您的
OR
( ||
),因为只有一部分条件需要为true
,因此该条件整体返回true
。
To resolve this, you're looking to check whether $currentpage
is equal to $homeurl
OR $currentpage
is equal to $homepage
: 为了解决这个问题,你打算检查是否
$currentpage
等于$homeurl
或 $currentpage
等于$homepage
:
if ($currentpage == $homeurl || $currentpage == $homepage)
Which, with added brackets, evaluates to: 使用括号将其评估为:
if ( ($currentpage == $homeurl ) || ($currentpage == $homepage) )
Hope this helps! 希望这可以帮助! :)

It's because your if statement is checking to see if $homepage
is set, not if $homepage
is equal to $currentpage
. 这是因为您的if语句正在检查是否设置了
$homepage
,而不是如果$homepage
等于$currentpage
。
if ($currentpage == $homeurl || $currentpage == $homepage) {
echo '<div class="hero"></div>';
}
