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>
<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
if(isset($_POST["submit"]))
{
if(isset($_POST["subject"]))
{
foreach ($_POST['subject'] as $subject)
print "You selected $subject<br/>";
}
else
echo "Select an option first !!";
