I need to upload multiple files to a server using the curl command line

  • 0

I need to upload multiple files to a server using the curl command line utility. for a single file I have no problem using:

curl -F "image=@file1.gif"   http://localhost:8888/web/Upload.php

how would I do this with more than one file so that the php variable $_FILES[“image”][“error”] would return an array?

I’ve tried

curl -F "image=@file1.gif" -F "image=@file2.gif"  http://localhost:8888/web/Upload.php
curl -F "image=@file1.gif,image=@file2.gif"  http://localhost:8888/web/Upload.php

but these are a stab in the dark.

    The trick is to name the file uploading parameters unique.

    curl -F "image=@file1.gif" -F "image2=@file2.gif"  http://localhost:8888/web/Upload.php

    This will show up in the $_FILES superglobal as $_FILES['image'] and $_FILES['image2'].

    To make the files grouped under one $_FILES index you need to name the parameters as arrays:

    curl -F "image[]=@file1.gif" -F "image[]=@file2.gif"  http://localhost:8888/web/Upload.php
