3.4.2 Reading checkbox Values
The HTML <input type="checkbox" …/> form field is used to associate several possible values with a single form field name. Unlike a type="radio" field, which allows only one selection from a list, checkboxes allow multiple values to be selected. Consider this problem:
Document 3.11a (CloudObs.htm) <html> <head> <title>Cloud Observations</title> </head> <body bgcolor="#aaddff"> <h1>Cloud Observations</h1> <strong> Cloud Observations </strong>(Select as many cloud types as observed.) <br /> <form method="post" action="CloudObs.php" /> <table> <tr> <td><strong>High</strong> </td> <td> <input type="checkbox" name="high[]" value="Cirrus" /> Cirrus</td> <td> <input type="checkbox" name="high[]" value="Cirrocumulus" /> Cirrocumulus </td> <td> <input type="checkbox" name="high[]" value="Cirrostratus" /> Cirrostratus </td></tr> <tr> <td colspan="4"><hr noshade color="black" /> </td></tr> <tr> <td> <strong>Middle</strong> </td> <td> <input type="checkbox" name="mid[]" value="Altostratus" /> Altostratus </td> <td> <input type="checkbox" name="mid[]" value="Altocumulus" /> Altocumulus</td></tr> <tr> <td colspan="4"><hr noshade color="black" /> </td></tr> <tr> <td> <strong>Low</strong></td> <td> <input type="checkbox" name="low[]" value="Stratus" /> Stratus</td> <td> <input type="checkbox" name="low[]" value="Stratocumulus" /> Stratocumulus</td> <td> <input type="checkbox" name="low[]" value="Cumulus" /> Cumulus </td></tr> <tr> <td colspan="4"><hr noshade color="black" /> </td></tr> <tr> <td> <strong>Rain-Producing </strong> </td> <td> <input type="checkbox" name="rain[]" value="Nimbostratus" /> Nimbostratus</td> <td> <input type="checkbox" name="rain[]" value="Cumulonimbus" /> Cumulonimbus </td></tr> </table> <input type="submit" value="Click to process..." /> </form> </body> </html>
