Use the new Text Modules custom post type and display a text module by either shortcode or widget.
Have you ever wanted to use some pieces of text information more than once? For instance, contact information such as a postal address? Or some slogan, motto or claim?
This is exactly when Text Modules kicks in.
<h4>Usage</h4>
This plugin registers a simple post type for text modules. A text module can be accessed either via shortcode (by means of the text module’s ID or slug) or via a new Tex Modules widget.
Filters
In order to customize certain aspects of the plugin, it provides you with several filters. For each of these, a short description as well as a code example on how to alter the default behavior is given below. Just put the according code snippet in your theme’s <code>functions.php</code> file or your customization plugin, or to some other appropriate place.
<code>text_modules_after_widget_content</code>
This filter lets you alter the HTML after the widget content.
<pre><code>/**
 * Filter the HTML after the widget content.
 *
 * @param string $after_widget_content Some HTML after the widget content.
 */
add_filter( 'text_modules_after_widget_content', function() {

 return '';
} );
</code></pre>
<code>text_modules_before_widget_content</code>
This filter lets you alter the HTML before the widget content.
<pre><code>/**
 * Filter the HTML before the widget content.
 *
 * @param string $before_widget_content Some HTML before the widget content.
 */
add_filter( 'text_modules_before_widget_content', function() {

 return '';
} );
</code></pre>
<code>text_modules_post_type</code>
Yes, you can alter the post type (slug).
<pre><code>/**
 * Filter the post type.
 *
 * @param string $post_type Post type.
 */
add_filter( 'text_modules_post_type', function() {

 return 'exotic_stuff';
} );
</code></pre>
<code>text_modules_post_type_args</code>
If you want to alter a specific post type argument but you can’t find a fitting filter, there’s <code>text_modules_post_type_args</code>, which provides you with the complete args array.
<pre><code>/**
 * Filter the post type args.
 *
 * @param array $args Post type args.
 */
add_filter( 'text_modules_post_type_args', function( $args ) {

 // Use hierarchical external content
 $args[ 'hierarchical' ] = TRUE;

 return $args;
} );
</code></pre>
<code>text_modules_post_type_description</code>
The post type description can be customized by using the <code>text_modules_post_type_description</code> filter.
<pre><code>/**
 * Filter the post type description.
 *
 * @param string $description Post type description.
 */
add_filter( 'text_modules_post_type_description', function() {

 // Provide a description
 return 'Simple post type for text modules.';
} );
</code></pre>
<code>text_modules_post_type_labels</code>
In case you don’t like the labels, easily adapt them to your liking.
<pre><code>/**
 * Filter the post type labels.
 *
 * @param array $labels Post type labels.
 */
add_filter( 'text_modules_post_type_labels', function( $labels ) {

 // A little more horror, please...
 $labels[ 'not_found' ] = 'ZOMG, no text module found!!1!!1!!oneone!!!1!eleven!1!';

 return $labels;
} );
</code></pre>
<code>text_modules_post_type_supports</code>
This filter provides you with the post type supports.
<pre><code>/**
 * Filter the post type supports.
 *
 * @param array $supports Post type supports.
 */
add_filter( 'text_modules_post_type_supports', function( $supports ) {

 // Let's add revisions for our post type
 if ( ! in_array( 'revisions', $supports ) ) {
 $supports[] = 'revisions';
 }

 return $supports;
} );
</code></pre>
<code>text_modules_shortcode_apply_do_shortcode</code>
By default, do_shortcode() will be called on the shortcode output. Of course, you can change that.
<pre><code>/**
 * Filter if the shortcode should apply do_shortcode() to the output.
 *
 * @param bool $do_shortcode Should the shortcode apply do_shortcode()?
 */
add_filter( 'text_modules_shortcode_apply_do_shortcode', '__return_false' );
</code></pre>
<code>text_modules_shortcode_callback</code>
In case you would like to adapt how the shortcode data is handled, you can provide your own shortcode callback. This can either be a string holding the function name, or an array with either a class name or an object, and the according method.
<pre><code>/**
 * Filter the shortcode callback.
 *
 * @param array|string $callback Shortcode callback.
 */
add_filter( 'text_modules_shortcode_callback', function() {

 return 'my_text_modules_shortcode_callback';
} );
</code></pre>
<code>text_modules_shortcode_id_attribute_name</code>
This filter lets you alter the shortcode’s ‘id’ attribute name.
<pre><code>/**
 * Filter the 'id' shortcode attribute name.
 *
 * @param string $name Attribute name.
 */
add_filter( 'text_modules_shortcode_id_attribute_name', function() {

 return 'post_id';
} );
</code></pre>
<code>text_modules_shortcode_output</code>
This filter lets you alter the shortcode output. The second parameter holds the shortcode attributes array.
<pre><code>/**
 * Filter the shortcode output.
 *
 * @param string $output Shortcode output.
 * @param array $atts Shortcode attributes array.
 */
add_filter( 'text_modules_shortcode_output', function( $output ) {

 return $output . ' Over and out.';
} );
</code></pre>
<code>text_modules_shortcode_query_args</code>
Also, there’s <code>text_modules_shortcode_query_args</code>, which provides you with the complete args array for the shortcode’s query.
<pre><code>/**
 * Filter the shortcode query args.
 *
 * @param array $args Shortcode query args.
 */
add_filter( 'text_modules_shortcode_query_args', function( $args ) {

 // Exclude some text modules by ID
 $args[ 'post__not_in' ] = array( 4, 8, 15, 16, 23, 42 );

 return $args;
} );
</code></pre>
<code>text_modules_shortcode_slug_attribute_name</code>
This filter lets you alter the shortcode’s ‘slug’ attribute name.
<pre><code>/**
 * Filter the 'slug' shortcode attribute name.
 *
 * @param string $name Attribute name.
 */
add_filter( 'text_modules_shortcode_slug_attribute_name', function() {

 return 'post_slug';
} );
</code></pre>
<code>text_modules_shortcode_tag</code>
This filter lets you alter the shortcode’s tag.
<pre><code>/**
 * Filter the shortcode tag.
 *
 * @param string $shortcode_tag Shortcode tag.
 */
add_filter( 'text_modules_shortcode_tag', function() {

 return 'text_block';
} );
</code></pre>
<code>text_modules_shortcode_use_slug</code>
By default, text modules are being queried by their post ID first. Of course, you can change that and use the post slug instead.
<pre><code>/**
 * Filter if the shortcode (query) should use the post slug instead of the post ID.
 *
 * @param bool $use_slug Use slug instead of ID?
 */
add_filter( 'text_modules_shortcode_use_slug', '__return_true' );
</code></pre>
<code>text_modules_widget_form_query_args</code>
Also, there’s <code>text_modules_widget_form_query_args</code>, which provides you with the complete args array for the widget form’s query.
<pre><code>/**
 * Filter the widget form query args.
 *
 * @param array $args Query args.
 */
add_filter( 'text_modules_widget_form_query_args', function( $args ) {

 // Exclude some text modules by ID
 $args[ 'post__not_in' ] = array( 4, 8, 15, 16, 23, 42 );

 return $args;
} );
</code></pre>
