Display and hide content using checkbox in Options Framework Theme

Question

I am currently using Options Framework Theme for making WordPress options panel. I created a checkbox in admin panel by this code in options.php

$options[] = array(
'name' => __('Input Checkbox Name', 'options_framework_theme'),
'desc' => __('Check to display.'),
'id' => 'example_checkbox_2',
'std' => 'true',
'type' => 'checkbox');

I want to display different content when the checkbox is checked or unchecked. So, I inserted this code in file template (footer.php)

<?php if ( of_get_option('example_checkbox2') != 'true') { ?>
        <p>checked</p>
    <?php } else { ?>
        <p>unchecked</p>
<?php } ?>

My problem is:

When I checked or uncheck the checkbox, "checked" is displayed in my footer.

Could anybody help how to retrieve and display content from checkbox correctly?

Any respond are highly appreciated.

Thank you.

Answer 1

'true' should be '1':

$options[] = array(
    'name' => __('Input Checkbox Name', 'options_framework_theme'),
    'desc' => __('Check to display.'),
    'id' => 'example_checkbox_2',
    'std' => '1',
    'type' => 'checkbox'
);

and:

<?php if ( 1 == of_get_option('example_checkbox2') ) { ?>
        <p>checked</p>
    <?php } else { ?>
        <p>unchecked</p>
<?php } ?>
