1. 1 Insert, Update and Delete Queries

2. 2 Return to you Address Book database. Insert a record.

3. 3 Recall that this action provides the SQL, better yet it will provided the PHP that writes the SQL.

4. 4 Copy the code and put it somewhere for safe keeping

5. 5 Saved PHP-SQL code in Notepad

6. 6 Mark a record and click the pencil icon to update that record.

7. 7 Change some fields and click Go.

8. 8 Rats. I didn’t see any SQL Update query to copy.

9. 9 Mark a record and click on the Delete button

10. 10 Copy the SQL for the DELETE, then decide whether you want to delete this record or not.

11. 11 Saved DELETE query

12. 12 Start two PHP files, place a form and a table with one row and two columns on the first page.

13. 13 Add a list/menu and a submit button in column 1 and a radio group in column 2.

14. 14 Corresponding code.

15. 15 Add PHP code for putting names into list/menu.

16. 16 Result so far.

17. 17 Add a second form and second table with 1 row (to start) and 3 columns

18. 18 Corresponding code

19. 19 After the row ( ) but before end of table ( ), start PHP code block. Make array of database filed names.

20. 20 Write a foreach loop that iterates over the FieldArray making a table row corresponding to each

21. 21 Result so far.

22. 22 Add SQL query before foreach loop, edit middle column code.

23. 23 Result so far

24. 24 Add non-breaking space ( ) to middle column

25. 25 After non-breaking space was added to middle column

26. 26 Add if so no Old data is showing for “Insert” choice

27. 27 Problem The radio buttons do not hold onto the information about what choice was clicked before.

28. 28 The top form’s action is the same page, so it can refer to its own $_POST array. I add some php script in the radio button tags to check the appropriate radio button.

29. 29 Add if structure that “remembers” which item from the list was selected The extra word selected in the option tag will indicate which of the option should be showing.

30. 30 Added some code so that textboxes are read only and gray when Delete is the chosen action

31. 31 Remembers selected person, remembers selected action, grays out textboxes when delete is selected action.

32. 32 Add submit button to bottom form.

33. 33 Show old data in textbox (as starting point) when Update is selected action.

34. 34 Result showing old data in textbox (as starting point) when Update is selected.

35. 35 Insert Hidden Fields (to hold info from top form on bottom form so it can be passed to handler of bottom form)

36. 36 Result of hidden fields added

37. 37 PHP code to get values from top form onto bottom form

38. 38 Handler code to determine action requested on calling page
