i'm facing an issue with check if a checkbox is checked.
I have an array of custom post types. I want to list all of them with checkboxes. When the user check and save the page, the checkboxes should remain checked.
That's the code:
$options_pt = get_option( 'post_type_to_include' );
$post_types = get_post_types();
$remove_post_types = array('revision','nav_menu_item','custom_css','customize_changeset','acf-field-group','acf-field','wpcf7_contact_form','attachment','polylang_mo');
foreach ($remove_post_types as $remove_post_type) {
if (($key = array_search($remove_post_type, $post_types)) !== false) {
unset($post_types[$key]);
}
}
?>
<?php if($options_pt){
foreach ($post_types as $post_type) { ?>
<input type='checkbox' name='post_type_to_include[<?php echo $post_type; ?>]' <?php checked( $options_pt[$post_type], 1 ); ?> value='1'><?php echo $post_type; ?></br> <?php
}
} else {
foreach ($post_types as $post_type) { ?>
<input type='checkbox' name='post_type_to_include[<?php echo $post_type; ?>]' value='1'><?php echo $post_type; ?></br> <?php
}
}
What's coming out of this code is:
-When I select NO post type, everything works fine.
-When I select a post type, the selected post type works fine the remainder say this:
Notice: Undefined index: page in /*****/option.php on line 71
value='1'>page
Line 71 is: the checkbox in the first foreach.
Anybody know where the issue could be?
