我知道这是一个老问题,但对于那些寻找一个很好的解决方案,加里·彭德格斯特有一个很好的途径去覆盖一些在其他的答案中提到的依据(见他的岗位在这里,我已经更新了下面的代码来检查PHP版本,但实际上可以将其用于任何检查):
// In this example, only allow activation on WordPress 3.7 or higherclass
MyPlugin {
function __construct() {
add_action( 'admin_init', array( $this, 'check_version' ) );
// Don't run anything else in the plugin, if we're on an incompatible WordPress version
if ( ! self::compatible_version() ) {
return;
}
}
// The primary sanity check, automatically disable the plugin on activation if it doesn't// meet minimum requirements.static
function activation_check() {
if ( ! self::compatible_version() ) {
deactivate_plugins( plugin_basename( __FILE__ ) );
wp_die( __( 'My Plugin requires PHP 5.1 or higher!', 'my-plugin' ) );
}
}
// The backup sanity check, in case the plugin is activated in a weird way,
// or the versions change after activation.
function check_version() {
if ( ! self::compatible_version() ) {
if ( is_plugin_active( plugin_basename( __FILE__ ) ) ) {
deactivate_plugins( plugin_basename( __FILE__ ) );
add_action( 'admin_notices', array( $this, 'disabled_notice' ) );
if ( isset( $_GET['activate'] ) ) {
unset( $_GET['activate'] );
}
}
}
}
function disabled_notice() {
echo '<strong>' . esc_html__( 'My Plugin requires PHP 5.1 or higher!', 'my-plugin' ) . '</strong>';
}
static function compatible_version() {
if ( version_compare(PHP_VERSION, '5.1', '<') ) {
return false;
}
// Add sanity checks for other version requirements here
return true;
}
}
global $myplugin;
$myplugin = new MyPlugin();
register_activation_hook( __FILE__, array( 'MyPlugin', 'activation_check' ) );
我还将上面的代码保存在要点中。
