PHP Having problem involving getting database content to show up after passing a query string.

Hello, I have been stuck on this and figured I would come here to seek assistance. The main objective of this project is to create an intranet and have the employee name link to a details.php which displays details about that specific employee. the problem I am having is that whenever I click on the employee name, it displays the text in the else statement rather than the text within the if statement. What are some ways I can remediate the issue?

Code below:



details.php:
<!DOCTYPE html> <html lang="en"> <head> </head> <body> <div class = "navigation"> <a href = "index.php"> Employees</a> </div> <?php require 'dbConn.php'; echo "<br>"; $employeeid = $_GET['employeeid']; $sql = 'SELECT e.employee_id, e.last_name, e.first_name, e.email, e.phone_number, d.department_name, j.job_title, e.hire_date, e.salary, d.location_id, l.city, l.state_province, l.country_id FROM employees as e, departments as d, jobs as j, locations as l WHERE e.employee_id = $employeeid and e.department_id = d.department_id and e.job_id = j.job_id and d.location_id = l.location_id ORDER by e.last_name'; $result = $mysqli->query($sql); $output = array($sql); if ($result !== false && $result->num_rows > 0) { // output data of each row while($row = $result->fetch_assoc()) { $output = array($row["first_name"] . $row["last_name"] . "<br>" . $row["job_title"] . $row["hire_date"]); } } else { echo "0 results"; } $mysqli->close(); ?> </body> </html>
 
Have you tried echoing out the SQL query you are running and pasting it directly into your database program? If you get zero results when you are expecting a result that would cause the else to trip. Also, a syntax error in the query would also be treated like a no-result.
