Hello guys, in the make your own WP plugin, for some reason my $display_tooltip variable is not accesible in the front-end.php template. My code never enters <?php if( $display_tooltip == '1' ): ?> even when it's checked in the settings.
I tried to debut it by printing its value but it's not even defined.
I believed than an update in WP broke the code of the course and is no longer compatible. Probably in the "update function"
For reference:
function widget( $args, $instance ) {
// Widget output
extract( $args );
$title = apply_filters( 'widget_title' , $instance['title'] );
$num_badges = $instance['num_badges'];
$display_tooltip = $instance['display_tooltip'];
$options = get_option( 'wptreehouse_badges' );
$wptreehouse_profile = $options['wptreehouse_profile'];
require( 'inc/front-end.php' );
}
function update( $new_instance, $old_instance ) {
// Save widget options
$instance = $old_instance;
$instance['title'] = strip_tags($new_instance['title']);
$instance['num_badges'] = strip_tags($new_instance['num_badges']);
$instance['display_tooltip'] = strip_tags($new_instance['display_tooltip']);
return $instance;
}
function form( $instance ) {
// Output admin widget options form
$title = esc_attr($instance['title']);
$num_badges = esc_attr($instance['num_badges']);
$display_tooltip = esc_attr($instance['display_tooltip']);
$options = get_option( 'wptreehouse_badges' );
$wptreehouse_profile = $options['wptreehouse_profile'];
require( 'inc/widget-fields.php' );
}
Please help, I already lost 8 hours on this one... Thank you so much!!!

Unfortunately I don't have a smoking gun for you, but FWIW I just completed this project and I can affirm that in my project the tooltips displayed as expected. My version of WP was 3.9.1 w/ 2014 theme, working on local server. I went through your included code line by line, did not see any discrepancies.
I'm not sure if you are at the stage where you expect to be seeing tooltips and are not seeing them or if something else prompted you to check the value for $display_tooltip. My guess is it's the former. If you haven't tried it, you may want to comment out your code and paste in the project code for sections that you suspect aren't working as expected.
On a related note, the exact section you have above I spent an hour (at least) today debugging an issue in which the tooltip setting would not update. FINALLY tracked it down that I had display_tooltip as $display_tooltip for the index in the form function - argh. I finally found it by comparing little snippets of the project code to my code. So I've gotten quite acquainted with the section you have above, do not see any errors. But may still want to try A/B'ing it. Good luck!

16,297 PointsThank you SO MUCH for your thorough answer it helped me a great deal. Unfortunately I was dumb enough to put the widget in the "Secondary area" and not with the rest of the widgets and for some reason the theme we are using doesn't "activate" the secondary zone...
So frustrating... But it's behind me.. I really appreciate your help!!
