wordpress复制插件上传文件到主题目录

Question

I have a line of code that is supposed to copy image from one directory to another:

copy("http://localhost:8080/wordpress/wp-content/uploads/2015/06/uploaded_background.jpg","http://localhost:8080/wordpress/wp-content/themes/landing-page/img/desktop-background.jpg");

This is located in wordpress theme header.php file, however I am receiving an error message:

Warning: copy(http://localhost:8080/wordpress/wp-content/themes/landing-page/img/desktop-background.jpg): failed to open stream: HTTP wrapper does not support writeable connections in C:\wamp\www\wordpress\wp-content\themes\landing-page\header.php on line 42

Line 42 is where my copy function line is located.

How can I solve this issue. Any suggestions or links would help a lot.

Answer 1

instead of using

 copy("http://localhost:8080/wordpress/wp-content/uploads/2015/06/uploaded_background.jpg","http://localhost:8080/wordpress/wp-content/themes/landing-page/img/desktop-background.jpg");

try

copy`("/yourserverfolderpath/wordpress/wp-content/uploads/2015/06/uploaded_background.jpg","/yourserverfolderpath//wordpress/wp-content/themes/landing-page/img/desktop-background.jpg");`

yourserverfolderpath/ could be something like /home/user/abc/

see you ftp or cpanel for exact path

see this SO question as guideline

PS: In case of local file, path would be something like D:\php\www\www\xml.php

as pointed by @dlegall in comments and as per documentation, First param of copy() can be a valid URL, see the docs here
