Create custom shortcodes and reusable content and insert them in into your posts and pages.

== Description ==

> Create custom shortcodes and reusable content and insert them in into your posts and pages.

This plugin lets you build a library with snippets of HTML, PHP code or reoccurring text that you often use in your posts and pages. You can use predefined variables to replace parts of the snippet on insert. All snippets are available in the post editor via a button in the Visual mode. The snippet can be inserted as defined, or as a shortcode to keep flexibility for updating the snippet. PHP code is supported for snippets inserted as shortcodes.

= Features =

* **Insert** All defined snippets is inserted from a button directly in the post editor.
* **Shortcodes** You can use this plugin to create your own custom shortcodes.
* **PHP** A shortcode snippet can optionally be processed as PHP code.
* **Buttons** The snippets can be found in the (visual) WordPress editor with a button and in the HTML editor with a quicktag.
* **User-friendly** Easy to use 'Manage Snippets' page where you can add, edit and remove snippets.
* **Variables** Each snippet can have as many custom variables as you like, which can be used on insert.
* **Import/Export** Snippets can be imported and exported between sites.
* **Documentation** Full documentation is available directly from the help panel in the plugin (top right in WordPress).
* **Uninstall** If you delete the plugin from your plugins panel it cleans up all data it has created in the WordPress database.

= Requirements =

* PHP version 5.3.0 or greater.
* WordPress version 3.3 or greater.

= Automatic installation =

1. Install the plugin via Plugins > New plugin. Search for 'Post Snippets'.
2. Activate the 'Post Snippets' plugin through the 'Plugins' menu in WordPress.

2. Select Post Snippets in the 'Recently Active Plugins' section and select
   'Delete' from the 'Bulk Actions' drop down menu.

== Frequently Asked Questions ==

= Where can I the documentation? =

Documentation for the plugin is available directly from the Help panel in the
plugin administration screen (top right corner of WordPress).

= Why does importing Snippets on a Multisite installation fail? =

Uploading of zip files must be allowed, enable this in Sites Network Admin > Settings > Upload Settings > Upload file types.

= How can I use the content in an enclosed shortcode? =

If the shortcode is enclosed and contains content between the tags in a post. Example: `[shortcode]Some text[/shortcode]` the text within will be available in a variable called content. So in your snippet use {content} to display it. Don't enter 'content' in the variable field, it's automatically assigned.

= Where can I get support? =

Please visit the [Support Forum](https://wordpress.org/support/plugin/post-snippets) for questions, answers, support and feature requests.

= Can I disable the PHP Code Execution feature? =

To disable the "PHP Code" execution feature in this plugin, add the following code your theme's functions.php or to wp-config.php: `define('POST_SNIPPETS_DISABLE_PHP', true);`

This is useful if you are using this plugin for client sites, and don't want
your clients to be able to use PHP code in a post snippet.
