Question

wp_installing( bool $is_installing = null )

Check or set whether WordPress is in “installation” mode.

---

description

If the WP_INSTALLING constant is defined during the bootstrap, wp_installing() will default to true.

---

参数

$is_installing

(bool) (Optional) True to set WP into Installing mode, false to turn Installing mode off. Omit this parameter if you only want to fetch the current status.

Default value: null

返回值

(bool) True if WP is installing, otherwise false. When a $is_installing is passed, the function will report whether WP was in installing mode prior to the change to $is_installing.

源代码

File: wp-includes/load.php

	static $installing = null;

	// Support for the `WP_INSTALLING` constant, defined before WP is loaded.
	if ( is_null( $installing ) ) {
		$installing = defined( 'WP_INSTALLING' ) && WP_INSTALLING;
	}

	if ( ! is_null( $is_installing ) ) {
		$old_installing = $installing;
		$installing = $is_installing;
		return (bool) $old_installing;
	}

	return (bool) $installing;
