How can I select and upload multiple files with HTML and PHP using HTTP POST

Question

I have experience doing this with single file uploads using  lt input type  file  gt    However  I am having trouble doing uploading more than one at a time   For example  I d like to be able to select a series of images  then upload them to the server  all at once   It would be great to use a single file input control  if possible   Does anyone know how to accomplish this   Thanks

If you use multiple input fields you can set name  file     or any other name   That will put them in an array when you upload them    FILES  file     array   file array   file array

in the first you should make form like this     lt form method  post  enctype  multipart form-data   gt      lt input type  file  name  file    multiple id  file   gt      lt input type  submit  name  ok     gt   lt  form gt     that is right   now add this code under your form code or on the any page you like    lt  php if isset   POST  ok        foreach    FILES  file    name   as  filename        echo  filename   lt br  gt        gt    it s easy    finish

If you want to select multiple files from the file selector dialog that displays when you select browse then you are mostly out of luck  You will need to use a Java applet or something similar  I think there is one that use a small flash file  I will update if I find it   Currently a single file input only allows the selection of a single file   If you are talking about using multiple file inputs then there shouldn t be much difference from using one  Post some code and I will try to help further     Update  There is one method to use a single  browse  button that uses flash  I have never personally used this but I have read a fair amount about it  I think its your best shot   http   swfupload org

There are a few things you need to do to create a multiple file upload  its pretty basic actually  You don t need to use Java  Ajax  Flash  Just build a normal file upload form starting off with    lt form enctype  multipart form-data  action  post upload php  method  POST  gt    Then the key to success     lt input type  file  name  file    multiple   gt    do NOT forget those brackets  In the post upload php try the following    lt  php print r   FILES  file    tmp name       gt    Notice you get an array with tmp name data  which will mean you can access each file with an third pair of brackets with the file  number  example      FILES  file    tmp name   0    You can use php count   to count the number of files that was selected  Goodluck widdit
