    I have made a form (selection of books), with multi selection checkbox. I have not added any values to them, because i am planning to show selective data in pdf only.
    I have gone through all the documentation, i easily used this code to make show list of selected items.

    /* Output in a list */
if ( is_array( $form_data['field'][1] ) ) {
    echo '<ul>';

    foreach ( $form_data['field'][1] as $item ) {
        echo "<li>$item</li>";
    }

    echo '</ul>';
}

    Then i wanted to pass this data in array and show selective data using if,else statements. I used this code

    <?php 
   $book = $form_data['field'][1];
  
?>

    Then used this code for initial statement

    
<p>You have chosen <?php echo $book; ?> Here is the explanation!</p>

    but is showing this statement

    “You have chosen Array Here is the explanation!”

    From where did the array came??
    Can anyone help?

    Hi Junaid,

    Checkbox fields are stored as PHP arrays in $form_data because users can select more than once answer. That’s why the initial snippet you’ve included above loops through that array to output the data. If you only want a user to select one answer I’d recommend a Radio or Select field instead.

    If you’re happy allowing users to select multiple options, you can convert the array to a string first:

    
<?php $books = implode( ', ', array_filter( (array) $form_data['field'][1] ) ); ?>
<p>You have chosen <?php echo $books; ?> Here is the explanation!</p>

    Also, if you’d like to conditionally show content based on the Checkbox field you can do something like this:

    
<?php if ( in_array( 'Book', (array) $form_data['field'][1] ) ): ?>
    Conditional content
<?php endif; ?>
