<p>A very simple shortcode series to create a text area which can be hidden or displayed based on a click on the title. Text areas by default are hidden.</p>
<p>This shortcode series uses jQuery functionality to a) determine which text areas are to be toggled and b) toggle them.</p>
<h4>Use</h4>
<p>Basic use is to surround a block of text with the “[tt]” shortcode and specify a title parameter within the shortcode. The title will be shown on the page, preceeded by an indicator whether the associated text area is hidden (►) or shown (▼). Clicking the title link will toggle the display of the dependant text area, as well as toggle the indicator.</p>
<p>Groups of text areas can be shown or hidden at once through the “[tt_part]” and “[tt_all]” shortcodes.</p>
<p>The “[tt_part]” shortcode uses a required parameter named “class” that links it to all “[tt]” shortcodes and their associated text areas with the same class parameter. Clicking the “[tt_part]” title link will toggle all associated text areas and any “[tt_part]” shortcode links with the same class according to the status of the parent shortcode. Text areas of this section that are already displayed when the parent link is clicked will remain displayed, and vice versa with hidden text areas.</p>
<p>The “[tt_all]” shortcode will toggle all “[tt]” shortcode text areas, any intermediate “[tt_part]” links and any mirrored “[tt_all]” links, according to the status of the particular title link. Text areas that are already displayed when the overall link is clicked to display all the text areas will remain displayed, and vice versa with hidden text areas.</p>
<p>Both the “[tt_part]” and “[tt_all]” shortcodes may be placed anywhere on the web page and can be used multiple times on the same web page.</p>
<h4>Parameters</h4>
<p>The “[tt]” shortcode has one required parameter and two optional parameters, plus the required content of the shortcode.</p>
<ul>
<li>The “class” parameter is optional: this links the particular text area with the “[tt_part]” shortcode, which can display or hide groups of text areas. This parameter must consist of only letters and numbers.</li>
<li>The “style” parameter is optional: this allows the author to apply CSS style components to the given shortcode content, which will only be visible when the content is made visible. Style components are limited to anything that applies to the area surrounding and including the area to be displayed and are limited to the following: background-color, border, border-color, border-radius, border-size, border-style, and color. Any other style components or any other text will be ignored. </li>
<li>The “title” parameter is required: this what is displayed as the title of the text area and is used as the control link. </li>
</ul>
<p>The “[tt_part]” short code has two required parameters; it does not use any content.</p>
<ul>
<li>The “class” parameter is required: this is the link to all associated “[tt]” text areas. This parameter must consist of only letters and numbers.</li>
<li>The “title” parameter is required: this what is displayed as the title of the control link, preceded by “Show / Hide All”.</li>
</ul>
<p>The “[tt_all]” short code has no parameters and it does not use any content.</p>


Text Toggle

A very simple shortcode series to create a text area which can be hidden or displayed based on a click on the title. Text areas by default are hidden.

Widgetlogic.org

<p>This plugin gives every widget an extra control field called “Widget logic” that lets you control the pages that the widget will appear on. The text field lets you use WP’s <a href="https://codex.wordpress.org/Conditional_Tags" rel="nofollow ugc">Conditional Tags</a>, or any general PHP code.</p>
<p>PLEASE NOTE The widget logic you introduce is EVAL’d directly. Anyone who has access to edit widget appearance will have the right to add any code, including malicious and possibly destructive functions. There is an optional filter ‘widget_logic_eval_override’ which you can use to bypass the EVAL with your own code if needed. (See <a href="other_notes/" rel="nofollow ugc">Other Notes</a>).</p>
<p>The configuring and options are in the usual widget admin interface.</p>
<p>BIG UPDATE:</p>
<ul>
<li>
<p>Now you can control widget in Gutenberg Widgets editor as well as in Classic Editor. It is just as easy as before but also in gutenberg view.</p>
</li>
<li>
<p>Pre-installed widgets let you add special widget with one click of the mouse. First pre-installed widget is Live Match that let you add widget of one random live football game with real time score updates (teams logos, livescore, minute of the match, tournament name). And more interesting widgets to come!</p>
</li>
</ul>
<h4>Configuration</h4>
<p>Aside from logic against your widgets, there are three options added to the foot of the widget admin page (see screenshots).</p>
<ul>
<li>
<p>Use ‘wp_reset_query’ fix — Many features of WP, as well as the many themes and plugins out there, can mess with the conditional tags, such that is_home is NOT true on the home page. This can often be fixed with a quick wp_reset_query() statement just before the widgets are called, and this option puts that in for you rather than having to resort to code editing</p>
</li>
<li>
<p>Load logic — This option allows you to set the point in the page load at which your widget logic if first checked. Pre v.50 it was when the ‘wp_head’ trigger happened, ie during the creation of the HTML’s HEAD block. Many themes didn’t call wp_head, which was a problem. From v.50 it happens, by default, as early as possible, which is as soon as the plugin loads. You can now specify these ‘late load’ points (in chronological order):</p>
<ul>
<li>after the theme loads (after_setup_theme trigger)</li>
<li>when all PHP loaded (wp_loaded trigger)</li>
<li>after query variables set (parse_query) – this is the default</li>
<li>during page header (wp_head trigger)</li>
</ul>
<p>You may need to delay the load if your logic depends on functions defined, eg in the theme functions.php file. Conversely you may want the load early so that the widget count is calculated correctly, eg to show an alternative layour or content when a sidebar has no widgets.</p>
</li>
<li>
<p>Don’t cache widget logic results — From v .58 the widget logic code should only execute once, but that might cause unexpected results with some themes, so this option is here to turn that behaviour off. (The truth/false of the code will be evaluated every time the sidebars_widgets filter is called.</p>
</li>
</ul>
<h4>Interaction with External Services</h4>
<p>Widget Logic uses the external service to obtain up-to-date information about the results of football matches. <a href="https://widgetlogic.org" rel="nofollow ugc">widgetlogic.org</a> is a source of sports information, that provides a wide range of information about football, including various leagues, tournaments, and championships from around the world.</p>
<p>The functioning of the <a href="https://widgetlogic.org" rel="nofollow ugc">widgetlogic.org</a> service is based on delivering real-time data about selected matches without the need to refresh the page. This means that data is automatically updated without requiring page reload. This approach ensures users quick and uninterrupted access to the latest sports data without the effort of manually updating information, allowing them to stay informed about ongoing events in real-time.</p>
<h3>Writing Logic Code</h3>
<p>The text in the ‘Widget logic’ field can be full PHP code and should return ‘true’ when you need the widget to appear. If there is no ‘return’ in the text, an implicit ‘return’ is added to the start and a ‘;’ is added on the end. (This is just to make single statements like is_home() more convenient.)</p>
<h4>The Basics</h4>
<p>Make good use of <a href="https://codex.wordpress.org/Conditional_Tags" rel="nofollow ugc">WP’s own conditional tags</a>. You can vary and combine code using:</p>
<ul>
<li><code>!</code> (NOT) to <strong>reverse</strong> the logic, eg <code>!is_home()</code> is TRUE when this is NOT the home page.</li>
<li><code>||</code> (OR) to <strong>combine</strong> conditions. <code>X OR Y</code> is TRUE when either X is true or Y is true.</li>
<li><code>&&</code> (AND) to make conditions <strong>more specific</strong>. <code>X AND Y</code> is TRUE when both X is true and Y is true.</li>
</ul>
<p>There are lots of great code examples on the WP forums, and on WP sites across the net. But the WP Codex is also full of good examples to adapt, such as <a href="https://codex.wordpress.org/Template_Tags/in_category#Testing_if_a_post_is_in_a_descendant_category" rel="nofollow ugc">Test if post is in a descendent category</a>.</p>
<h4>Examples</h4>
<ul>
<li><code>is_home()</code> — just the main blog page</li>
<li><code>!is_page('about')</code> — everywhere EXCEPT this specific WP ‘page’</li>
<li><code>!is_user_logged_in()</code> — shown when a user is not logged in</li>
<li><code>is_category(array(5,9,10,11))</code> — category page of one of the given category IDs</li>
<li><code>is_single() && in_category('baked-goods')</code> — single post that’s in the category with this slug</li>
<li><code>current_user_can('level_10')</code> — admin only widget</li>
<li><code>strpos($_SERVER['HTTP_REFERER'], "google.com")!=false</code> — widget to show when clicked through from a google search</li>
<li><code>is_category() && in_array($cat, get_term_children( 5, 'category'))</code> — category page that’s a descendent of category 5</li>
<li><code>global $post; return (in_array(77,get_post_ancestors($post)));</code> — WP page that is a child of page 77</li>
<li><code>global $post; return (is_page('home') || ($post->post_parent=="13"));</code> — home page OR the page that’s a child of page 13</li>
</ul>
<p>Note the extra ‘;’ on the end where there is an explicit ‘return’.</p>
<h3>The ‘widget_logic_eval_override’ filter</h3>
<p>Before the Widget Logic code is evaluated for each widget, the text of the Widget Logic code is passed through this filter. If the filter returns a BOOLEAN result, this is used instead to determine if the widget is visible. Return TRUE for visible.</p>
