Example Courses and its subjects. </p> <p>With this form I need to check how many sub items have selected for a one category. And also I need to look over at least one sub category has selected in all main category and if it is ok want to limit upto 10 sub categories to select. </p> <p>I tried it something like this.. but here its count all selected subcategories. </p> <pre><code>if ( isset ( $_POST['sub-category']) && is_array( $_POST['sub-category'])) { $totalCategory = count( $_POST['sub-category']); if ( $totalCategory >= 1 && $totalCategory <= 10 ) { $_SESSION['sub-category'] = $_POST['sub-category']; $url = BASE_URI . 'register.php'; // Define the URL: header("Location: $url"); exit(); // Quit the script. } else { echo 'ERROR: Please select atleast 1, not more than 10.'; } } else { echo 'ERROR: Please select atleast one category.'; } </code></pre> <p><strong>UPDATE:</strong></p> <p>This is PHP I use to generate from </p> <pre><code>echo "<input type='checkbox' value='{catId:subID}' name='subject{$lastCatId}[]' />{$lastCatName}"; </code></pre> <p>Them HTML generate something like this..</p> <pre><code><h3>Main Category 01 <input type='checkbox' value='3:4' name='subject3[]' />sub category <input type='checkbox' value='3:6' name='subject3[]' />sub category <h3>Main Category 02 <input type='checkbox' value='4:6' name='subject4[]' />sub category <input type='checkbox' value='4:2' name='subject4[]' />sub category <h3>Main Category 01 <input type='checkbox' value='5:8' name='subject5[]' />sub category <input type='checkbox' value='5:4' name='subject5[]' />sub category </code></pre> <p>Problem is how I get sub categories' values separately and then need to count...</p> <p>I hope someone help me out...

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.
