I am trying to come up with a php if statement for my site. I have a page called "research". There is text on this page with a link which says "contact me" This link links through to my contact page. Now, I need an if statement to say that if you are on the research page and you click on the contact me link, I need some text on the contact me page to be hidden and only be visible when you are on the contact page.
Is this possible?
On your contact page, you can get what you are looking for from:
$_SERVER['HTTP_REFERER']. It will tell you which page the user came from getting to the contact page.
However, you should not rely on this. Consult the following Q&A here on Stack Overflow:
