Wordpress禁用插件停用的功能：該代碼將移除插件中的 Deactivate 鏈接，將下面代碼保存到 functions.php 并保存。
add_filter( 'plugin_action_links', 'slt_lock_plugins', 10, 4 );
function slt_lock_plugins( $actions, $plugin_file, $plugin_data, $context ) {
// Remove edit link for all
if ( array_key_exists( 'edit', $actions ) )
unset( $actions['edit'] );
// Remove deactivate link for crucial plugins
if ( array_key_exists( 'deactivate', $actions ) && in_array( $plugin_file, array(
'slt-custom-fields/slt-custom-fields.php',
'slt-file-select/slt-file-select.php',
'slt-simple-events/slt-simple-events.php',
'slt-widgets/slt-widgets.php'
)))
unset( $actions['deactivate'] );
