## 描述

You are developing things on a WordPress site and would like to have a _snapshot_
of the current state of your site? **SnapShots** will help you save states of your
WordPress environment.

 * Save snapshots of your site with a simple click.
 * Name your snapshots for easy distinction.
 * SnapShots stores current location and redirects after restore.
 * Stores and restores database tables and files in upload folder.
 * Automatically logs in current user.
 * Automatically clears old snapshots with same name.
 * Small footprint and minimal UI.

### Options

All options are defined via constants and can get overwritten with a filter. The
format of options is

    ```
    SNAPSHOTS_[OPTION_NAME]
    ```

Best to define your custom option constants in the `wp-config.php` file.

You can use filters options like

    ```
    add_filter( 'snapshots_[option_name]', function( $default_option ){
     return $my_option;
    });
    ```

#### Default Options

    ```
    // Default save location.
    SNAPSHOTS_FOLDER : WP_CONTENT_DIR . '/.snapshots'

    // add '--allow-root' to each command if you run the commands as root.
    SNAPSHOTS_CLI_ALLOW_ROOT: false

    // define the location of your 'wp' binaries.
    SNAPSHOTS_CLI_PATH: '/usr/local/bin'

    // Number of shots kept with the same name.
    SNAPSHOTS_MAX_SHOTS: 2

    // SnapShot includes files from content folder.
    SNAPSHOTS_SAVE_FILES: true

    // SnapShot includes location (URL) during creation to redirect on restore.
    SNAPSHOTS_SAVE_LOCATION: true
    ```

## 安装

 1. Upload `snapshosts` to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Click on “Click here to create your first Snapshot!” in the admin bar to create
    your first Snapshot.
 4. Restore the saved snapshot by clicking on the menu entry and confirm.
 5. All tables not used in the current SnapShot with the DB prefix will be removed!

## 常见问题

### What are the requirements for SnapShots

You need [WP CLI](https://wp-cli.org/) installed (at least version 2.2) and PHP 
must be able to execute external programs with PHPs [`exec`](https://www.php.net/manual/en/function.exec.php)

### Does it work without WP CLI?

No, WP CLI is essential here and SnapShots will not work without it. You will not
be able to activate the plugin without the addon.

### Does it work with “Local”

Yes, the plugin has been tested with the [amazing tool](https://localwp.com/) from
WPEngine and works out of the box.

### Snapshots requires the php in your PATH environment

SnapShots tries to find the `php` binary on your system. If it can’t find it, you
will get this error. You can define the location of your `php` binary by open your
terminal and running

    ```
    `
    ```

dirname $(which php)
 `

This returns the directory of your php binary. Use this location to define the constant`
SNAPSHOTS_PHP_PATH` in your `wp-config.php` file. For example:

    ```
    `
    ```

define( ‘SNAPSHOTS_PHP_PATH’, ‘/usr/local/bin’ );
 `

**Don’t include the `php` binary in the path!**

### Your Home URLs do not match

Snapshots checks if the home URL of your site matches the one from `wp option get
home`. If they are not equal it often that the `DB_HOST` variable is not defined
correctly. This also happens if you use a socket for your MySql connection (Local
WP).

Update your DB_HOST variable in your `wp-config.php` file to something like this:

    ```
    `
    ```

define( ‘DB_HOST’, ‘localhost:/tmp/ysql/mysqld.sock’ );
 `

This should not affect the regular usage of your site. If you encounter any problems,
You can wrap the statement like so:

    ```
    `
    ```

if ( defined( ‘WP_CLI’ ) && WP_CLI ) {
 define( ‘DB_HOST’, ‘localhost:/tmp/ysql/
mysqld.sock’ ); }else{ define( ‘DB_HOST’, ‘localhost’ ); } `

### Snapshots requires the “exec” method

SnapShots uses the PHP [`exec`](https://www.php.net/manual/en/function.exec.php)
method to execute the WP CLI commands.

    ```
    `
    ```

### Snapshots requires WP-CLI!

SnapShots requires the [WP-CLI](https://wp-cli.org/) to be installed on your system.
Please install it and make sure it is available in your `PATH` environment.

I use this plugin on all my sites. It takes snapshots of the database and allows
me to revert to some version. 1.2, 1.3 and so on. Really good and it just “works”.
Definitely download this. Cheers.

 [toomanyphils](https://profiles.wordpress.org/toomanyphils/) 2024 年 2 月 22 日

When activating this plugin I get an error saying the wp executable doesn’t exist.
Now, I don’t have ssh access to my client’s site, but wordpress.com says wp-cli 
is pre-installed. So either wordpress.com’s documentation is incorrect, or this 
plugin uses a hardcoded path to the executable which doesn’t match wordpress.com’s
installation directory

This plugin is very usefull when you need to make small modifications during your
site development phase. You can very quickly roll back to the previous version of
your site. I had some difficulties to get everything working but the developer was
very helpfull and provided options on how to solve the problem. Thanks a lot for
such a useful plugin!
