HTML Form elements array

Creating array of HTML form elements

Array is a collection of similar data elements, means we can use array to store similar elements referenced under a common name.

In web development sometimes we need to group HTML form elements as arrays do. For example, you have a form where user has to select his hobbies from a group of check boxes as given below.









Sample Code

<form action="showlist.php" method="post" name="hobby_frm">
<h3> Select your hobbies </h3>
<input type="checkbox" name="hobbies[]" value="hb1"  />
Reading <br />
<input type="checkbox" name="hobbies[]" value="hb2" />
Surfing <br />
<input type="checkbox" name="hobbies[]" value="hb3" />
Listening to music  <br />
<input type="submit" value="submit" />
</form>

Please notice the name of all checkboxes hobbies[]
The above code will define an array with the name hobbies

Accessing form elements array using JavaScript

Now, let's see how to access the hobbies[] using JavaScript.

<script type="text/javascript">
var hobbies = document.hobby_frm.elements['hobbies[]'];
var str = "Length  : "+hobbies.length+"\n";
for( var i = 0; i < hobbies.length; i++ ) {
str = str + "Hobby "+(i+1)+" : "+hobbies[i].value+"\n";
}
alert(str);
</script>

Handle form elements array in PHP

In PHP, data sent from a form with post method is available in $_POST array.
We can access hobbies[] using the following code.

<?php
$hobbies = $_POST['hobbies']; // use name of the array as key
foreach( $hobbies as $value )
print $value;
?>
