Text Hover free WordPress plugin

This plugin allows you to easily define help text that appears when a visitor hovers their mouse over a word or phrase in a post or page. Via the plugin’s settings, simply specify the words or phrases that you want to be associated with hover text, and of course, the desired hover texts themselves. The format is quite simple; an example of which is shown here: WP => WordPress Matt => Matt Mullenweg The Scooby Shack => the bar where the gang hangs out Additional features of the plugin controlled both via settings and filters: Hover text can be enabled for comments (it isn’t by default) Hover text can be made case insensitive (it is case sensitive by default) Hover text can be limited to doing only one replacement per term, per post (by default, all occurrences of a term are given hovertext) Hover text can be rendered using the default browser tooltip (by default, the better-looking qTip2 library is used) Note: This is not the same as my Text Replace plugin, which defines terms or phrases that you want replaced by replacement text when displayed on your site. Text Hover instead adds the hover text as additional information for when visitors hover over the term, which is otherwise displayed in the post as you typed it.

Typically, the code to utilize these hooks would go inside your active theme’s functions.php file. Bear in mind that all of the features controlled by these filters are configurable via the plugin’s settings page. These filters are likely only of interest to advanced users able to code. c2c_text_hover_filters (filter) The ‘c2c_text_hover_filters’ hook allows you to customize what hooks get text hover applied to them. Arguments: $hooks (array): Array of hooks that will be text hovered. Example: /** * Enable text hover for post/page titles. * * @param array $filters Filters handled by the Text Hover plugin. * @return array */ function more_text_hovers( $filters ) { $filters[] = ‘the_title’; // Here you could put in the name of any filter you want return $filters; } add_filter( ‘c2c_text_hover_filters’, ‘more_text_hovers’ ); c2c_text_hover_third_party_filters (filter) The ‘c2c_text_hover_third_party_filters’ hook allows you to customize what third-party hooks get text hover applied to them. Note: the results of this filter are then passed through the c2c_text_hover_filters filter, so third-party filters can be modified using either hook. Arguments: $filters (array): The third-party filters whose text should have text hover applied. Default array( ‘acf/format_value/type=text’, ‘acf/format_value/type=textarea’, ‘acf/format_value/type=url’, ‘acf_the_content’, ‘elementor/frontend/the_content’, ‘elementor/widget/render_content’ ). Example: /** * Stop text hovers for ACF text fields and add text hovers for a custom filter. * * @param array $filters * @return array */ function my_c2c_text_hover_third_party_filters( $filters ) { // Remove a filter already in the list. unset( $filters[ ‘acf/format_value/type=text’ ] ); // Add a filter to the list. $filters[] = ‘my_plugin_filter’; return $filters; } add_filter( ‘c2c_text_hover_third_party_filters’, ‘my_c2c_text_hover_third_party_filters’ ); c2c_text_hover_filter_priority (filter) The ‘c2c_text_hover_filter_priority’ hook allows you to override the default priority for the ‘c2c_text_hover’ filter. Arguments: $priority (int): The priority for the ‘c2c_text_hover’ filter. The default value is 2. $filter (string): The filter name. Example: /** * Change the default priority of the ‘c2c_text_hover’ filter to run after most other plugins. * * @param int $priority The priority for the ‘c2c_text_hover’ filter. * @return int */ function my_change_priority_for_c2c_text_hover( $priority, $filter ) { return 1000; } add_filter( ‘c2c_text_hover_filter_priority’, ‘my_change_priority_for_c2c_text_hover’, 10, 2 ); c2c_text_hover (filter) The ‘c2c_text_hover’ hook allows you to customize or override the setting defining all of the text hover terms and their hover texts. Arguments: $text_hover_array (array): Array of text hover terms and their hover texts. This will be the value set via the plugin’s settings page. Example: /** * Add dynamic text hover. * * @param array $text_hover_array Array of all text hover terms and their hover texts. * @return array */ function my_text_hovers( $text_hover_array ) { // Add new term and hover text $text_hover_array[‘Matt’] => ‘Matt Mullenweg’; // Unset a term that we never want hover texted if ( isset( $text_hover_array[‘Drupal’] ) ) unset( $text_hover_array[‘Drupal’] ); // Important! return $text_hover_array; } add_filter( ‘c2c_text_hover’, ‘my_text_hovers’ ); c2c_text_hover_text_comments (filter) The ‘c2c_text_hover_text_comments’ hook allows you to customize or override the setting indicating if text linkification should be enabled in comments. Arguments: $state (bool): Either true or false indicating if text linkification is enabled for comments. The default value will be the value set via the plugin’s settings page. Example: // Prevent text linkification from ever being enabled in comments. add_filter( ‘c2c_linkify_text_comments’, ‘__return_false’ ); c2c_text_hover_case_sensitive (filter) The ‘c2c_text_hover_case_sensitive’ hook allows you to customize or override the setting indicating if text hover should be case sensitive. Arguments: $state (bool): Either true or false indicating if text hover is case sensitive. This will be the value set via the plugin’s settings page. Example: // Prevent text hover from ever being case sensitive. add_filter( ‘c2c_text_hover_case_sensitive’, ‘__return_false’ ); c2c_text_hover_once (filter) The ‘c2c_text_hover_once’ hook allows you to customize or override the setting indicating if text hovering should be limited to once per term per piece of text being processed regardless of how many times the term appears. Arguments: $state (bool): Either true or false indicating if text hovering is to only occur once per term. The default value will be the value set via the plugin’s settings page. Example: // Only show hovertext for a term/shortcut once per post. add_filter( ‘c2c_text_hover_once’, ‘__return_true’ ); c2c_text_hover_use_pretty_tooltips (filter) The ‘c2c_text_hover_use_pretty_tooltips’ hook allows you to customize or override the setting indicating if text hovering should use prettier tooltips to display the hover text. If false, the browser’s default tooltips will be used. Arguments: $state (bool): Either true or false indicating if prettier tooltips should be used. The default value will be the value set via the plugin’s settings page. Example: // Prevent pretty tooltips from being used. add_filter( ‘c2c_text_hover_use_pretty_tooltips’, ‘__return_false’ );
