Wordpress get_option not working - php

Question

I want to get array value from get_option following this answer to add more but its not working for me. I can't find where I have gone wrong. It works when I am not using array.
Working code (without array):
add_action('admin_init', function() {
register_setting('my-test', 'option1');
register_setting('my-test', 'option2');
register_setting('my-test', 'option3');
});
function my_function() {
?>
<div class="wrap">
<h1>Dashboard</h1>
<form action="options.php" method="post">
<?php
settings_fields('my-test');
do_settings_sections('my-test');
?>
<input type="text" name="option1" value="<?php echo esc_attr( get_option('option1') ); ?>"" />
<?php submit_button(); ?>
</form>
</div>
<?php
}
Then I want to use array to get_option. I followed the answer I mention above but it gives me error. Please see this code below.

function my_function() {
$new_option = esc_attr(get_option('option2'));
?>
<div class="wrap">

?>
<input type="text" name="option1" value="<?php echo esc_attr( get_option('option1') ); ?>"" />
<input type="text" name="option2[first]" value="<?php echo $new_option['first']; ?>" />
<input type="text" name="option2[second]" value="<?php echo $new_option['second']; ?>" />
<?php submit_button(); ?>
</form>
</div>
<?php
}
Am I missing something? Any help is much appreciated. Thanks in advance.

Answer 1

Remove esc_attr function in the below line. This function takes string as input and returns string. Since you are dealing with array this will cause error.
$new_option = get_option('option2');
You should use the function where you are actually outputting the value.
<input type="text" name="option2[first]" value="<?php echo esc_attr( $new_option['first'] ); ?>" />
Hope it helps. :)
