Lesson 22 - Add more form objects
Actions
 |
Click to see Lesson22_MoreObjects.php in action on this tutorial site. Note: if you enter name an email in this form, you will send me an email. |
Download this file: Lesson22_MoreObjects.txt to your PC. Change the txt extension to php. Change the “recipient address” in the Lesson22 file and the pointers to the style sheet and then upload all to your website. The “thank yous” should be there from the previous lesson.
Surf to the Lesson22_MoreObjects.php file on your website with your browser. You should see results similar to the image above on the right.
After completing the form and clicking “Send me more info”, you should receive an email with this in the body:
Please send me more information about Acme products
First Name = your first name
Last Name = your last name
Email = you@yourdomain.com
My interests are:
Favorite Characters = Bugs Bunny, Daffy Duck, Wiley Coyote
Age Group = Adult
Add me to mailing list = No
Comments =first line
second line
third line
And, you should receive a confirming email.
And, you should be sent to the Thank You page.
Gotchas
If your PHP configuration has '--enable-magic-quotes' as this one does, you will get some strange results in your emails if your visitor types quotes. For example, if your visitor types: "we are the best" in the comments, the email sent to you will contain: \"we are the best\". The next lesson will fix this.
Source Code
This is all standard HTML stuff, except that we have to retain all the typed-in values when we print error messages.
