In our previous tutorials, we have performed various operations on different form elements using Javascript and jQuery. In this tutorial, our concern is to get values of multiple checked checkboxes using PHP as follows:

 To get  value of a checked checkbox :

<form action="#" method="post">
<input type="checkbox" name="gender" value="Male">Male</input>
<input type="checkbox" name="gender" value="Female">Female</input>
<input type="submit" name="submit" value="Submit"/>
</form>
<?php
if (isset($_POST['gender'])){
echo $_POST['gender']; // Displays value of checked checkbox.
}
?>

To get value of multiple checked checkboxes, name attribute in HTML input type=”checkbox” tag must be initialize with an array, to do this write [ ] at the end of it’s name attribute :

<form action="#" method="post">
<input type="checkbox" name="check_list[]" value="C/C++"><label>C/C++</label><br/>
<input type="checkbox" name="check_list[]" value="Java"><label>Java</label><br/>
<input type="checkbox" name="check_list[]" value="PHP"><label>PHP</label><br/>
<input type="submit" name="submit" value="Submit"/>
</form>
<?php
if(isset($_POST['submit'])){//to run PHP script on submit
if(!empty($_POST['check_list'])){
// Loop to store and display values of individual checked checkbox.
foreach($_POST['check_list'] as $selected){
echo $selected."</br>";
}
}
}
?>

In our example, there is a form contains some checkboxes, User checks them and when he/she hits submit button, multiple values of checkboxes will be display.

Watch our live demo or download our codes to use it.

Our example’s complete HTML and PHP codes are given below.

HTML Codes: php_checkbox.php
Given below our complete HTML codes.

<!DOCTYPE html>

<input type="checkbox" name="check_list[]" value="UNIX/LINUX"><label>UNIX/LINUX</label>
<input type="submit" name="submit" Value="Submit"/>
<!----- Including PHP Script ----->
<?php include 'checkbox_value.php';?>
</form>
</div>
</div>
</body>
</html>

PHP Codes: checkbox_value.php

In the below script, we used foreach loop to display individual value of checked checkboxes, we have also used a counter to count number of checked checkboxes.

<?php
if(isset($_POST['submit'])){
if(!empty($_POST['check_list'])) {
// Counting number of checked checkboxes.
$checked_count = count($_POST['check_list']);
echo "You have selected following ".$checked_count." option(s): <br/>";
// Loop to store and display values of individual checked checkbox.
foreach($_POST['check_list'] as $selected) {
echo "<p>".$selected ."</p>";
}
echo "<br/><b>Note :</b> <span>Similarily, You Can Also Perform CRUD Operations using These Selected Values.</span>";
}
else{
echo "<b>Please Select Atleast One Option.</b>";
}
}
?>

Conclusion:
Once you got the value of checked checkbox(es), you can also perform CRUD (Create, Read, Update & Delete) operations in database. Hope you like it, keep reading our other blogs.
