File Upload Progress

[optikalefx]

I'm looking for ideas on the best way to do this.

 

I made a program in PHP that takes in 2 mp4 files, it grabs a screen shot using ffmpeg from 1, and then uploads all 3 files to FTP.

 

However all this happens all at once, with no indication of what is going on.  I'm having a lot of trouble figuring out how to do the file upload part with ajax because It has to be sent from the Form so the $_FILES array is set with the right information.  So i tried out some iframes and its not going well.

 

My idea so far, which is failing, is to just do the FTP and open a separate window that checks the size of the files and returns them.  But its getting very convoluted, and popups suck.

 

Any suggestions on a different approach?

I modified this to upload video files, it works great

so your are creating an iframe and re creating the form and submitting that? How can you then access the $_FILES?

 

Care to provide an explanation?

!Apparently! you cant upload a file by ajax, but the link i gave you uses a javascript iframe. The functionality is identical to ajax

Not quite, I can't get feedback easily.

 

Lets say I use the hidden iframe and it uploads the data.  How can i access $FILES['file']['tmp_name'] back in js?

 

Would you say maybe echo out the data you wanted and use iframe.contentDocument.body. whatever and go get the data that way?

	var iframe = document.createElement("iframe");
iframe.setAttribute("id","ajax-temp");
iframe.setAttribute("name","ajax-temp");
iframe.setAttribute("width","0");
iframe.setAttribute("height","0");
iframe.setAttribute("border","0");
iframe.setAttribute("style","width: 0; height: 0; border: none;");
form.parentNode.appendChild(iframe);
window.frames['ajax-temp'].name="ajax-temp";

I think i found a great example

they use the hidden iframe but load the data back in JSON to get easily.  I like this way a lot.
