This is the upload function, first ready! It seems that I was from which the great God to find. Don't remember, sorry!

1 <? PHP 2 $path=$_get[' Timepath ']. ' /‘. $_get [' CompanyID ']. ' /‘. $_get [' Timepath ']. ' -‘. $_get [' Shopid ']. TXT '; 3 $downResult=logftpdownload ($path);

Stitch the path string, call the function, and pass in the path string!

Here, it's almost done! However, this is the ideal state, that is, the page does not have any output, the path $path is written dead, because the header (), can not have any output.

This situation is generally used with JS to solve, the front page with Ajax asynchronous submission to the background query related, processing data, if the file path is relatively single, even can be combined with a good path $path, my due to too many conditions, the file path is not the same, so only the data processing good, back to the front desk, Ajax judgment callback, if successful, use window.open (); Open a new window and pass the relevant parameters to the background controller, of course, preferably openwindow=window.open (); Assign it to close, and then give a intervalid =window.setinterval ("function name", 1000); This is the function named after opening a new window 1 seconds later, this function is used to display the exception thrown in the background, such as the file does not exist, FTP login, connection failure and so on.

This is probably the case, I am a small rookie, write this is to organize their own ideas, deepen the impression! Also hope that the gods come to guide you.
