PHP error on get_search_form()

[seansmyth]

When using a search form like below,

echo get_search_form();

or

get_search_form();

a php error occurs.

Warning: Undefined array key "echo" in .../wp-includes/general-template.php on line 363

As it was producing a php error

Warning: Undefined array key "echo" in /general-template.php on line 363

Hi there, welcome to WordPress Trac! Thanks for the ticket and the patch!

At first I thought that while echo is one of the default arguments​ for get_search_form(), some plugin or theme could unintentionally remove it via the search_form_args filter, but it looks like the function already protects against that, see [49355] / #51645:

// Ensure that the filtered arguments contain all required default values.
$args = array_merge( $defaults, $args );

Looking at the error:

Warning: Undefined array key "echo" in .../wp-includes/general-template.php on line 363

it is worth noting that in WordPress 6.0.2, the if ( $args['echo'] ) conditional in question is line 357​, not 363.

So I think the following would be helpful to move the ticket forward:

• Could you share the steps to reproduce the issue on a clean install?
• What is the version of WordPress you're using?

Adding a suggestion to close due to a lack of reporter feedback. Will circle back in a bit more time to close unless more details are shared.
