This plugin adds super simple social sharing buttons to your content.

== Description ==

_Scriptless Social Sharing_ is a wee plugin to add buttons to your posts/pages, to make it easier for your readers to share your content on social networks.

The sharing links use the most basic methods provided by each network. There is no JavaScript, nothing fancy included in this plugin, so if you want fancy, this is not the plugin you're looking for. It just builds a set of links.

The sharing buttons are accessible--even if you choose the "Icons Only" button styles, the network names are still part of the buttons, just hidden in an accessible-ready manner.

There is a small settings page, so you can make decisions about which content types should have sharing buttons and where, what buttons should be added, and whether or not to use the plugin's styles. Beyond that, developers may like to make use of filters throughout the plugin.

== Installation ==

1. Upload the entire `scriptless-social-sharing` folder to your `/wp-content/plugins` directory.
1. Activate the plugin through the 'Plugins' menu in WordPress.
1. Visit the Settings > Scriptless Social Sharing page to change the default behavior of the plugin.

== Frequently Asked Questions ==

= How are the social network icons/buttons displayed? =

In version 3.0, very differently than they have been before. Originally, Scriptless used the Font Awesome webfont (version 4.7) to display icons, or you could roll your own. You still can roll your own, but as of 3.0, Scriptless has updated to Font Awesome 5.8.1. SVG icons are now the default. The webfont is still an option, and previous users will need to update their settings to switch to SVG.

Text only buttons are now an option as well. And if you prefer flexbox for styling items in rows instead of table CSS, that's now available on the settings page.

= What social networks are supported? =

Scriptless Social Sharing currently supports the following social networks:

* Twitter
* Facebook
* Pinterest
* LinkedIn
* Reddit
* WhatsApp
* Pocket
* Telegram
* SMS
* Email

Google+ is dead and has been removed from the plugin. Instagram does not support social sharing buttons.

= Can I change the SVG icons? =

Yes, using a filter, you can change which SVG icons are used. The plugin provides SVG alternatives for social networks if they are available. Want to use an icon not provided by the plugin? Load your own icons in your theme.

Here's an example of how you could switch to using the "square" icons for each network (not all networks have one):

	add_filter( 'scriptlesssocialsharing_svg_icons', 'rgc_use_square_icons' );
	/**
	 * Change the Scriptless Social Sharing SVG icons to use the square versions when available.
	 *
	 * @param $icons
	 *
	 * @return array
	 */
	function rgc_use_square_icons( $icons ) {
		$square_icons = array(
			'email'     => 'envelope-square',
			'facebook'  => 'facebook-square',
			'pinterest' => 'pinterest-square',
			'reddit'    => 'reddit-square',
			'twitter'   => 'twitter-square',
			'whatsapp'  => 'whatsapp-square',
		);

		return array_merge( $icons, $square_icons );
	}

= What if I want to move where the buttons are output? =

Version 2.0.0 changes everything here. The plugin now offers options for adding sharing buttons to each and every type of content on your site. Buttons can be added in multiple places, or easily add support so you can add buttons anywhere you like. The default button locations are:

* Before Content: at the beginning of the post/entry, within the post/entry content.
* After Content: at the end of the post/entry, within the post/entry content.
* Manual: select this if you are adding buttons with your own code (this ensures that the necessary styles are loaded, and some other housekeeping).

To take advantage of the new location options, you must visit the plugin settings page and update your settings.

**Note:** if you have code that removes the original buttons output and adds it back by hand, make sure that you select Manual for the location for each affected content type.

The best way to change the button output location is by using a filter. This example changes the locations from using `the_content` filter (with `hook` set to `false`) to using action hooks instead.

	add_filter( 'scriptlesssocialsharing_locations', 'prefix_change_sss_locations' );
	function prefix_change_sss_locations( $locations ) {
		$locations['before'] = array(
			'hook'     => 'genesis_before_entry',
			'filter'   => false,
			'priority' => 8,
		);
		$locations['after'] = array(
			'hook'     => 'loop_end',
			'filter'   => false,
			'priority' => 8,
		);

		return $locations;
	}

If you use the Genesis Framework, there is a setting to tell the plugin to use Genesis hooks instead.

= Is there a Scriptless block? =

Yes! Introduced in version 3.0, the new sharing block allows you to put sharing buttons anywhere in your content. Add just a few buttons, or rely on the default configuration defined on the settings page.

= What about a shortcode? =

As of version 2.0.0, you can add sharing buttons directly to your content with a shortcode. You can tweak the output, too. For example, to add the buttons to your content, exactly as you have them set up in your settings, just use this shortcode:

	[scriptless]

If you want to remove the heading, try it this way (or customize the heading by adding text):

	[scriptless heading=""]

Want to only show certain buttons in the shortcode? Add them as a shortcode attribute (separate with commas, no spaces). This will show just the email and facebook buttons:

	[scriptless buttons="email,facebook"]

= Can I add sharing buttons to posts on archive pages? =

Yes. First, you have to tell the plugin that it can, in fact, run, even on the relevant archive page:

	add_filter( 'scriptlesssocialsharing_can_do_buttons', 'prefix_add_buttons_archives' );
	function prefix_add_buttons_archives( $cando ) {
		if ( is_home() || is_tax() || is_category() ) {
			$cando = true;
		}
		return $cando;
	}

Then you can add the buttons to the individual posts (this example works only with the Genesis Framework):

	add_action( 'genesis_entry_content', 'prefix_scriptlesssocialsharing_buttons_entry_content', 25 );
	function prefix_scriptlesssocialsharing_buttons_entry_content() {
		if ( ! function_exists( 'scriptlesssocialsharing_do_buttons' ) ) {
			return;
		}
		$is_disabled = get_post_meta( get_the_ID(), '_scriptlesssocialsharing_disable', true );
		if ( ! $is_disabled && ! is_singular() ) {
			echo wp_kses_post( scriptlesssocialsharing_do_buttons() );
		}
	}

= Some posts are missing the Pinterest button. Why is that? =

Yes, this is intentional. Pinterest really really _really_ wants your posts to have an image. The Pinterest button breaks if there isn't an image. The plugin looks in three places to find one: 1) the custom Pinterest image; 2) the post featured image; and 3) if there is no featured image set, it picks the first image uploaded to that specific post. At this point, if there is still no image, rather than putting up a button which won't work, the plugin won't output a Pinterest button at all on that particular post.

= What is this "Custom Pinterest Image"? =

You can add an image for the plugin to use specifically for Pinterest, instead of the post's featured image. This image will be added to the Pinterest sharing button as well as hidden in your content, so that the Pinterest bookmarklet will be able to "see" the image.

= How can I change the order of the sharing buttons? =

As of version 2.3, the sharing buttons order can be changed on the settings page, either by dragging buttons to your desired order, or by updating the numbered inputs.
