Warning: ftp_put() expects parameter 1 to be resource, boolean given in

Question

I am trying to do a form that upload a few fields, and 3 images. The images will be uploaded via FTP, there is a problem connecting to ftp with ftp_connect() when the php is uploaded to remote server. It couldn't connect to server when the php is in the shared host. But when the php is in the localhost, it display no error. I am now trying to make this work on Localhost and ftp_put the images into the remote server first, to isolate the error. At the moment i am getting this error.

Which is this ftp_put($login,"abc.info/$photo",$_FILES["file"]["tmp_name"][$i],FTP_ASCII)

Answer 1

ftp_put() requires a valid resource which is obtained by using ftp_connect(). If you are seeing this error message your call to ftp_connect() failed. You need to obtain a valid resource with ftp_connect(), and if you can't, you need to figure out what is causing your script not to connect to the remote host as that is the root cause of your problem.

To prevent your script from failing you should wrap your attempt to FTP in an if statement that checks to see if ftp_connect() connected successfully:

if (($resource = ftp_connect($host)) !== false) {
    // do FTP stuff
}
