PHP Error

[PunkUK]

Hi, can anyone please explain why I am getting this error:
pro/functions.php on line 341

Notice: Trying to get property of non-object in /home/chocol37/public_html/myersfitness.co.uk/wp-content/themes/infinity-pro/functions.php on line 341

Here is the php:
/** Add the featured image section */
add_action( 'genesis_after_header', 'full_featured_image' );
function full_featured_image() {
if ( is_front_page() ) {
echo '<div id="full-image"></div>';
}
elseif ( is_singular( array( 'post', 'page' ) ) && has_post_thumbnail() ){
echo '<div id="full-image">';
echo get_the_post_thumbnail($thumbnail->ID, 'header');
echo '</div>';
}
}

When I use this in Altitude Pro it is fine.

Many thanks to anyone who can help.

Since you didn't post line numbers, which line is causing the hiccup?

Hi Victor,

Thank you so much for replying. The line is: echo get_the_post_thumbnail($thumbnail->ID, 'header');

Many thanks.

Where are you initializing $thumbnail->ID?

You're passing an object element as a parameter, but you're not initializing the object anywhere. The error is correct.

This is how to use that function: https://developer.wordpress.org/reference/functions/get_the_post_thumbnail/

Hi Victor,

Thank you again for your reply. I wish I could answer your question but I don't know the answer. I used this code on the Altitude Pro theme and it works fine but for some reason I get this error with Infinity Pro.

If you have any suggestions I would most grateful. Would help to see the full functions PHP?

If that seems to work in Altitude Pro, then you are either not hitting the condition to trigger the notices, PHP notices are turned off, or you missed copying the code where that parameter is initialized. There's no way that code should work anywhere without initializing the parameter.

The theme has nothing to do with whether that code works or not.

You are passing an uninitialized object as a parameter to the WordPress get_the_post_thumbnail() function. The first parameter is either the post id or null. The default is null.

I would go back to wherever you got the code from and see what you're missing. I can't help you further without access to the back-end of the site.

If you can't figure this out, you may have to hire a developer to help you.
