I just succesfully followed the learning activity of pdf creation depicted in article.
During the study I updated also the examples at version 1.50 (not easy job)
Here attached the result of my job.
In the structure of my working installation zend library is under the root
and the modules are in root\understanding_zend ( as per zip ).
The savedentries table structure must be updated as
//for code to lesson from 1 to 4 se my previous post
Listing 21. Adding a new column to the table
ALTER TABLE `savedentries` ADD `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY;
code is in index post that resumes all my post about this activity (thanks to Elemental for more space)
