4. Validation
Validation is process of the checking data against a set of
parameters. If the parameters match, a true is returned,
otherwise false.
Validation can be used internally but it most commonly
used with checking user input.
In this tutorial, we will be briefly introducing you to
common validation used in PHP and its native
implementation in ProdigyView.

5. Integer Validation
Integer validation is a good point to start. An example
usage is many SQL databases use auto incremented ids
which are integers. You may want to verify that the id they
are going to use to update a record is an integer.

6. Double Validation
Double validation will cover validation for types double,
floats, longs, and anything else that contains a period
and a number. Passing an integer to double validation
will fail.

7. Email Validation
A common validation with web applications is the email.
You want the user who is registering for the application to
at least enter a real email.

8. Audio File Type
On your way to making the next Pandora? In that case
you want audio file mime type validation. While the
example below checks all audio mime types, it can be
further specified to check only one type.
Supported validation formats:
mp3, wav, ra, oga, midi, aif

9. Video File Types
Similar to the audio file type, video mime types can also be
validated. The example below is also all inclusive but video mime
types can be checked individually.
Supported Validation Formats:
ogv, mpeg, wmv, mp4, flv, quicktime, mov, mxu , avi, real
video, asf, webm

10. Image File Types
Check image file types before deciding to accept them.
Below is the method checking all images types but they
can also be checked individually.
Supported Validation Formats: png, gif, jpeg, ief, bmp,
tiff

11. Compress Files
Compressed files include zip, tar and gtar. Validate that
the file is actually a compressed file and does not merely
have the extension of a compressed file.

12. Microsoft Files
Microsoft files include Word, Excel and Powerpoint. Divided
further, we have .doc, docx and so forth, each which has
different mime-types. In ProdigyView, we can validate
against any of those Microsoft file types.

14. Challenge!
This is optional challenge that will help you better
understand Validation and File Management.
1. Located a video file on your computer/server.
2. With PVFileManager, retrieve the mime type of the
video file
3. Check against the file type specifically. Example, if the
video file is an avi, validate ONLY against avi files.
4. If the validation passed, copy the file to another
location using PVFileManager.
