Validating input type file

After the “Edit” button is clicked, a new window will open that allows us to edit the new script: This script also includes a check for an empty string, so that the user can wipe out a wrong string and start from scratch.As I mentioned before, information is passed to the validation function in the event object, and in the code we see that the member ‘value’ is used to communicate the current value of the field.

In that case, the previous value of the field is restored, and the user has to enter the data again.

Once submitted, the form above sends the file to upload_on the web server.

PHP stores the file in a temporary location until it is retrieved (or discarded) by the server side code.

This validator checks the markup validity of Web documents in HTML, XHTML, SMIL, Math ML, etc.

If you wish to validate specific content such as RSS/Atom feeds or CSS stylesheets, Mobile OK content, or to find broken links, there are other validators and tools available.
