DO THE FOLLOWING

Assignment Work

The first thing you need to do in orderform_v2.html is to change the form action from processorder.php to processorder_v4.php. Next you will edit the HTML in orderform_v2.html and the PHP code in processorder_v4.php.

Steps:

1. 1 pt Add a HTML text input form field with the name "notes" to the HTML in orderform_v2.html. You can put it above the submit button.

2. 2 pts Edit the PHP code in processorder_v4.php to display the output from the notes field you just added to the HTML form. Make sure to escape the notes field output using the htmlspecialchars function.

3. 2 pts Use the gettype function to get the type of all 4 form fields. Echo the type of each field as part of the output. For example: tireqty: string

4. 3 pts Use a cast or use the function intval to change the type of $tireqty, $oilqty, and $sparkqty to integer, but do not change the notes field as it should be a string. Use the gettype function again for all 4 form fields, and echo the type fo each field as part of the output.

5. 3 pts Add a check for each integer form variable to ensure they cannot be less than 0. If one of the fields is less than 0, instead of displaying the total, display an error message indicating the problem instead.

6. 1 pt Add a check to make sure that the total quantity of all the items is not 0. If the total quantity is 0, instead of displaying the total, display an error message indicating the problem instead.

Note for steps 5 and 6, you should avoid using the exit function and instead use an if/else/elseif statement to control whether the total is displayed or an error is displayed.

7. 1 pts The select box in the HTML named "find" will tell us how the customer found Bob's. Use it to report on how the customer found Bob's. Note that the value of the select box is one of a, b, c, or d so you will need to report the proper reason in the output, not those letters. You can use an array or if/elseif statements to accomplish this.

Total 13 pts
