Is Generatepress compatible with PHP 8?

I’m running GP pro on a local dev server using PHP8 and I’m seeing the following error message in the dashboard “add plugin” screen, when using GP pro as the theme:

Warning: Undefined property: stdClass::$plugin in D:\dev\www\testsite\wp-includes\class-wp-list-util.php on line 167

For reference, line 167 is:

$newlist[ $key ] = $value->$field;

from this section of code:

/**
* Plucks a certain field out of each element in the input array.
*
* This has the same functionality and prototype of
* array_column() (PHP 5.5) but also supports objects.
*
* @since 4.7.0
*
* @param int|string $field Field to fetch from the object or array.
* @param int|string $index_key Optional. Field from the element to use as keys for the new array.
* Default null.
* @return array Array of found values. If $index_key is set, an array of found values with keys
* corresponding to $index_key. If $index_key is null, array keys from the original
* $list will be preserved in the results.
*/
public function pluck( $field, $index_key = null ) {
$newlist = array();

if ( ! $index_key ) {
/*
* This is simple. Could at some point wrap array_column()
* if we knew we had an array of arrays.
*/
foreach ( $this->output as $key => $value ) {
if ( is_object( $value ) ) {
$newlist[ $key ] = $value->$field;
} else {
$newlist[ $key ] = $value[ $field ];
}
}

$this->output = $newlist;

return $this->output;
}

The issue doesn’t occur with the WP 2020 or 2021 themes, and all plugins have turned off, and no caching is in operation.

Thanks for your help.

Hi there,

haven’t see that before and i cannot replicate it on my dev servers running PHP 8.0.0 on WP 6.0 with wp_debug enabled.

But i did find theres an open bug on WP core trac:

https://core.trac.wordpress.org/ticket/44582

its quite an old bug by the looks of it, so i don’t think its related to 8.0 but more like an issue in the WP Transients.

Can you confirm which versions of WP and PHP ?

Thanks for the outstanding support!

The functions code snippet at the end of the link you sent fixed the issue, which turned out to be a reminder popup on the wp-admin plugins dashboard left behind by a deleted plugin.

Awesome – glad to be of help!
