Creating a Multi-File Upload Script in PHP

14:29:00


File upload is very common requirement of many web sites. We may require to upload pictures online to websites. Image upload is very common requirement and many sites are using this to allow members or visitors to upload files.


We will learn how to upload multiple files using a single form. This is required if you are allowing members to upload more than one file and you don't know how many files you allow them to upload. Say you want up to 8 files any member of your site can upload. As your members upload and delete files so at the time of displaying the form to allow them to upload you would like to check the existing number of files they have and accordingly display them upload fields to add files. 



Multiple files can be uploaded using different name for input. 



It is also possible to upload multiple files simultaneously and have the information organized automatically in arrays for you. To do so, you need to use the same array submission syntax in the HTML form as you do with multiple selects and checkboxes: 



Support for multiple file uploads was added in PHP 3.0.10.
