PHP if URL equals this then perform action
提问by Miles Pfefferle
So I have a page title that is part of a Magento template; I'd like it to display 1 of 2 options, depending on what the URL is. If the URL is option 1, display headline 1. If the URL is anything else, display headline 2. This is what I came up with, but it's making my page crash:
所以我有一个页面标题，它是 Magento 模板的一部分；我希望它显示 2 个选项中的 1 个，具体取决于 URL 是什么。如果 URL 是选项 1，则显示标题 1。如果 URL 是其他内容，则显示标题 2。这是我想出的，但它使我的页面崩溃：
<div class="page-title">
<h1><?php
$host = parse_url($domain, PHP_URL_HOST);
if($host == 'http://domain.com/customer/account/create/?student=1') {
echo $this->__('Create an account if you are a Post Graduate Endodontic Resident and receive our resident pricing. Please fill in all required fields. Thank you!')
}
else
{
echo $this->__('Create an Account')
}
?></h1>
</div>
Anyone have any ideas?
谁有想法？
EDIT: So it should look like this?
编辑：所以它应该是这样的？
$host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
if($host == 'http://domain.com/customer/account/create/?student=1')

Are you looking for the URL that the page is currently on? You are using parse_urlthe wrong way; that is if you only want to get the host, or domain, i.e. only "dev.obtura.com". It looks like you want more than that. In addition, you are never setting the $domainvariable, so parse_url()doesn't know what to do with it. So as it is now, your ifstatement will always return 'Create an account`.
您是否正在查找该页面当前所在的 URL？您以错误的方式使用parse_url；也就是说，如果您只想获取主机或域，即仅“dev.obtura.com”。看起来你想要的不止这些。此外，您从不设置$domain变量，因此parse_url()不知道如何处理它。因此，就像现在一样，您的if声明将始终返回“创建帐户”。
Instead, set $hostwith $_SERVERvariables:
相反，$host使用$_SERVER变量设置：
$host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
$host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
You will also need to remove the "http://" from your checking - $hostwill only contain everything after "http://"
您还需要从检查中删除“http://” -$host将只包含“http://”之后的所有内容
As Aron Cederholmsuggested, you need to add semicolons (;) to the end of your echo statements.
正如Aron Cederholm 所建议的，您需要;在 echo 语句的末尾添加分号 ( )。
So, your PHP code should look like this:
所以，你的 PHP 代码应该是这样的：
$host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
if($host == 'domain.com/customer/account/create/?student=1')
{
echo $this->__('Create an account if you are a Post Graduate Endodontic Resident and receive our resident pricing. Please fill in all required fields. Thank you!');
}
else
{
echo $this->__('Create an Account');
}

I'm not sure you're fetching the domain right. I don't really understand parse_url much, and you haven't shown us what $domainis defined as.
我不确定您是否正确获取了域。我不太了解 parse_url，你也没有向我们展示什么$domain是定义。
Normally if I want to get the domain name I would do this: $host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']Then the rest of your code.
通常，如果我想获得域名，我会这样做：$host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']然后是其余的代码。
That if, else statement seems legit to me, so I would try the above and see how that goes. ;)
if, else 语句对我来说似乎是合法的，所以我会尝试上面的方法，看看效果如何。;)

You should add semicolons to your statements inside your if-else.
您应该在 if-else 中的语句中添加分号。
if($host == 'http://dev.obtura.com/customer/account/create/?student=1') {
echo $this->__('Create an account if you are a Post Graduate Endodontic Resident and receive our resident pricing. Please fill in all required fields. Thank you!');
}
else
{
echo $this->__('Create an Account');
}
