<p>I'd highly recommend you use PDO, here's a sample using PDO.</p> <pre><code><?php $dsn = 'mysql:dbname=so;host=localhost'; $user = 'root'; $password = ''; // try to connect. try { $dbh = new PDO($dsn, $user, $password); } catch (PDOException $e) { echo 'Connection failed: ' . $e->getMessage(); exit(1); } // the sql which gets all employees for this company. $getEmployeesSQL = ''; $getEmployeesSQL .= ' SELECT c.name AS company_name, e.name AS employee_name, e.salary, c.location '; $getEmployeesSQL .= ' FROM company c'; $getEmployeesSQL .= ' LEFT JOIN employee e'; $getEmployeesSQL .= ' ON c.id = e.company_id'; $getEmployeesSQL .= ' WHERE c.name = :cname'; // sql to get company data. $companyDataSQL = "SELECT * FROM company WHERE name = :cname"; // prepare the sql. $stmtOne = $dbh->prepare($getEmployeesSQL); $stmtTwo = $dbh->prepare($companyDataSQL); // execute $stmtOne->execute(array(':cname' => $_GET['company'])); $stmtTwo->execute(array(':cname' => $_GET['company'])); // print results. $employees = $stmtOne->fetchAll(PDO::FETCH_ASSOC); $companyData = $stmtTwo->fetchAll(PDO::FETCH_ASSOC); /* * ****************************************** */ /* Iterate and print HTML table. */ /* * ****************************************** */ $html = '<table border="1">'; foreach ($companyData as $company) { foreach ($company as $field => $value) { $html.= "<tr><td>$field</td><td>$value</td></tr>"; } } $html . '</table>'; echo $html; $html = '<table border="1">'; foreach ($employees as $row) { $html.= '<tr><td>' . implode('</td><td>', array_values($row)) . '</td></tr>'; } $html . '</table>'; echo $html; </code></pre> <p>What this snippet does is that it prints the company data in a table and then gets employee data using company name.</p> <p>The table structure I'm using is as follows:</p> <pre><code>CREATE TABLE `company` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `name` varchar(200) NOT NULL, `location` varchar(200) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 CREATE TABLE `employee` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `name` varchar(200) NOT NULL, `salary` bigint(12) DEFAULT NULL, `company_id` bigint(20) NOT NULL, PRIMARY KEY (`id`), KEY `fk_company` (`company_id`), CONSTRAINT `fk_company` FOREIGN KEY (`company_id`) REFERENCES `company` (`id`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=latin1 </code></pre> <p>This returns data as follows: (Not pretty, but this'll have to do for now.)</p> <p><img src="https://i.stack.imgur.com/Zqfhr.png" alt="Result"></p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
