Join Bill Weinman for an in-depth discussion in this video Displaying the testimonials using PHP, part of PostgreSQL 9 with PHP Essential Training.
In the previous movie we looked at the code for managing the database for…testimonials application.…In this movie we are going to look at the code for displaying the testimonials.…Here you see them on the page here and when I reload, you see we get a different…set of random quotes.…Of course, these will be actual testimonials, in the real application,…we just got to fill it with some random quotes here.…And so in this movie we are going to look at the code that actually does that.…We'll take a given number of quotes out of the database and display them at random…every time it's reloading.…
So looking in our testimonial's folder from the Exercise Files you will see…a PHP file here called testimonials.php and we are going to open that in our editor.…This one is really very simple.…It's only 92 lines long.…At the top here we have our constants for connecting the database.…You will notice that there is an init function where we actually do connect to…the database and that should all be very familiar at this point.…
