hello guys i want to make my download system like
/download?file=815|file_name
and i already did that but when it appear in the google search in appear like
download?file=815%7Cfile_name
do you think is that good idea to add the file name in the url as a just name no variable
using special chars in the URL is not a good idea. What you can do is forgetting the standard url and use something like this : /download/815/filename and then use the URL Rewrite engine of apache.
Just use the file id download?file=8155555, I assume the path of the file is mapped to your db somewhere
Its not secure, But you like to use this format of url, You should check that urls variables/inputs by php user input injection methods.
Thats will help to secure your website.
1 more. In SEO purpose, good to skip the special symbols in the urls.
