PHP Form Data Validation Tips

February 7th, 2011 Michael DorfLeave a comment 2 comments

A common web task in web application development is to validate data input by a user. This is usually done to ensure that the type of data entered matches the expected data types for an underlying database. It is also a good security practice to limit the data that a web based form will accept. While it is common in web 2.0 applications to use client side code such as Javascript to validate form fields, this should not be relied on for a number of reasons. Some users disable Javascript so you want to provide a working… View full post »

reCAPTCHA with CakePHP Forms Tutorial

January 14th, 2011 Michael DorfLeave a comment

Unfortunately, as a developer today, you have to consider the possibility of spammers using automated scripts to submit the forms on your web site. One popular method for preventing this is to use a CAPTCHA. A CAPTCHA is an image that contains words or an alphanumeric code. The image is often slightly distorted. The user must correctly enter the words or code for the form to be considered valid. This prevents scripts from submitting forms since the CAPTCHA is not readable by automated systems.

January 3rd, 2011 Michael DorfLeave a comment 3 comments

There are cases when a web application may need to create a custom PDF file. There are several methods for accomplishing this as well. Recently, I worked on a project that involved an employment application. For this project, I needed to provide a HTML preview of the completed application as well as a PDF.
