Given a list of items and the task is to retrieve the multiple selected value from a select box using PHP.
Use multiple attribute in HTML to select multiple value from drop down list. Selecting multiple values in HTML depends on operating system and browser.
- For window users – hold down + CTRL key to select multiple option
- For mac users – hold down command key to select multiple option
Example: This example creates a list of items using HTML.
html
<html> <body> <form method = "post" action = "name.php"> <h4>SELECT SUBJECTS</h4> <!--Using multiple to select multiple value--> <select name = "subject" multiple size = 6> <option value = "english">ENGLISH</option> <option value = "maths">MATHS</option> <option value = "computer">COMPUTER</option> <option value = "physics">PHYSICS</option> <option value = "chemistry">CHEMISTRY</option> <option value = "hindi">HINDI</option> </select> <input type = "submit" name = "submit" value = Submit> </form> </body></html> |
Now, the task is to retrieve or print multiple selected value from list. Use form method and loop to retrieve selected value in PHP.
Example:
php
<html> <body> <!--name.php to be called on form submission--> <form method = 'post'> <h4>SELECT SUBJECTS</h4> <select name = 'subject[]' multiple size = 6> <option value = 'english'>ENGLISH</option> <option value = 'maths'>MATHS</option> <option value = 'computer'>COMPUTER</option> <option value = 'physics'>PHYSICS</option> <option value = 'chemistry'>CHEMISTRY</option> <option value = 'hindi'>HINDI</option> </select> <input type = 'submit' name = 'submit' value = Submit> </form> </body></html><?php // Check if form is submitted successfully if(isset($_POST["submit"])) { // Check if any option is selected if(isset($_POST["subject"])) { // Retrieving each selected option foreach ($_POST['subject'] as $subject) print "You selected $subject<br/>"; } else echo "Select an option first !!"; }?> |
Output:
Note: The form can be submitted using $_GET method. It depends on the form method=”?” value.
