What is the current path of ZF? Please help. Thank you! I have encountered a problem after studying zendframework for a while. I hope you guys can help solve this problem. thank you for working on the background, adminControll. php access is http: // URL/admin. I read this sentence in many places, including tutorials and so on. what is the current path of $ this ZF? Please help. Thank you.
The younger brother has just studied zendframework for a while and encountered a problem. I hope you can help us solve this problem. thank you first.
In my background, adminControll. php
Access is http: // URL/admin
I have read many articles, including tutorials, and so on. I wrote this sentence during initialization,
$ This-> view-> baseUrl = $ this-> _ request-> getBaseUrl ();
But I read the output, but it's just.
In addition, it does not play any role at all. I usually use $ this-> baseUrl in front of many links, but there is always an error when opening the page, that is, the correct link address is not obtained, up to now I can only write dead, such as the URL is http://www.123.com, now to see a articleAction. So I will die on the page, http://www.123.com/admin/article
If I change to $ this-> baseUrl. "/admin/article", an error may occur. for example, when I connect parameters to a single page, an error occurs at http://www.123.com/admin/article/act/edit/id/1. In this case, the obtained path is very bad.
Maybe I am confused, but I don't know if you can understand it?
My style may be affected by this path problem. Unless the path is written to death.
Use
Displayed correctly.
And on the http://www.123.com/admin/article/act/edit/id/1 page, there is an error. However, they call the same file with the same address path. in the Web site, there are many more folders. So it is wrong.
I am writing to death now. Direct
While Weburl;?> Is http://www.123.com
I would like to think that this method is too dead.
Is there any other way?
Thank you for your help.

------ Solution --------------------
Well, zf has a lot of url retrieval functions. It provides many flexible methods.
In phtml:
$ This-> baseUrl () indicates Yes
If the project is demo1
Indicates/demo1/public.
Both:
Http: // localhost/demo1/public
If your css is used
Echo $ this-> baseUrl (). '/styles/global.css'
That is:
Http: // localhost/demo1/public/styles/global.css

. The meaning of baseUrl is calculated from removing the domain name. In the future, do not use relative paths when resources are referenced. To be clear

If you use
$ This-> serverUrl () returns http: // localhost
