Section Search error

BIGB185 · October 18, 2019

I'm working on the following assignment and keep coming up with error messages.

"Warning: require(mysqli_connect_registrar.php): failed to open stream: No such file or directory in /home/students/r/b.richards/public_html/cis231/labs/sectionresults.php on line 3

Fatal error: require(): Failed opening required 'mysqli_connect_registrar.php' (include_path='.:/usr/share/pear:/usr/share/php') in /home/students/r/b.richards/public_html/cis231/labs/sectionresults.php on line 3"

I've included the code I have and any help would be appreciated.

Thank you.

Assignment Directions:

Introduction

This lab will demonstrate how to create a dynamic form that is created from database contents. And then that form will be used to pull results from the database, based on the user's selection.

STEP 1 - Create the Database Connection File

In your labs directory, define a mysql_connect.php file for the registrar database (with the student | student credentials).

STEP 2 - Create the Form

Define the form as sectionsearch.php. Create a dynamic form with a drop-down menu listing available courses by title. (Note: the courseID will be the value that is posted to the results page.)

Step 3 - Create the Results page

Define the results page as sectionresults.php. Present the results of the query for sections (unless there are none—then show an appropriate message).

If there are results, use an HTML table (dynamically-generated) to display available sections with the following information:

Faculty last name

Room number

Class meeting day(s)

Start time

End time

The information should be sorted by the faculty member's last name.

Note: You will need to consult the structure of the database tables to determine which fields need to be drawn from which tables and how to join the appropriate tables needed for the query.

Are you sure you know the name of the file?

(Use the code <> button in the toolbar when posting code)

EDIT: Stop using "@" to suppress errors - you want to know when things have gone wrong
