The problem is your update function. $old_instance is kind of special variable. The simplest is function update($new_instance, $old_instance) { return $new_instance; } For the safe function update($new_instance, $old_instance) { $instance = array(); $instance[‘name’] = htmlentities($new_instance[‘name’]); $instance[‘divclass’] = htmlentities($new_instance[‘divclass’]); $instance[‘paypal’] = htmlentities($new_instance[‘paypal’]); return $instance; }

You can’t pass this variable to the_title() but you can simply wrap it in wp_trim_words function. echo wp_trim_words( get_the_title(), $number_of_words );
Without seeing the code it’s a difficult problem to solve, but it sounds like something else is overwriting your code. You may need to be more specific about the H4 you’re targeting footer h4 for instance. You may also need to add !important to your CSS declaration in order to get it to work. See … Read more
Technically your first example is also incorrect, but the problem is not apparent. You’re using template tags that themselves echo their content. For example, you can write simply: the_permalink(); without echo, and the permalink will be output. This is because that function echoes its value. To output the permalink within an echo or variable assignment … Read more
Not sure what you’re after here, another options maybe possible, but there’s e.g. this hook: /** * Filters a widget’s settings before saving. * * Returning false will effectively short-circuit the widget’s ability * to update settings. * * @since 2.8.0 * * @param array $instance The current widget instance’s settings. * @param array $new_instance … Read more

So I’d suggest you to use the_style as the name for both the radio buttons: <p> <input class=”radio” type=”radio” <?php checked( $instance[ ‘the_style’ ], ‘style_1’ ); ?> id=”<?php echo $this->get_field_id( ‘the_style_1’ ); ?>” name=”<?php echo $this->get_field_name( ‘the_style’ ); ?>” value=”style_1″ … Read more
This worked for me: add_filter( ‘wp_dropdown_cats’, function( $html, $args ) { if ( $args[‘taxonomy’] === ‘product_cat’ ) { $html = str_replace( ‘<select’, ‘<select data-placeholder=”New Placeholder”‘, $html ); } return $html; }, 10, 2);
You can use the filter widget_title and a “virtual” shortcode. Of course, as One Trick Pony points out, the “why” (and the “what”) is essential to find a proper solution… Supposing the widget title was Title [php] More Title: add_filter( ‘widget_title’, ‘pseudo_php_wpse_90360’, 10, 3 ); function pseudo_php_wpse_90360( $title, $instance, $id_base ) { if( FALSE === … Read more
