Hide empty widget

    First i thought it was my theme, but it is the same problem even with one of the default WP themes.

    I searched for 1-2 days and found nothing.

    Situation is very simple.
    – Use Text widget with PHP support
    – Put some PHP code inside to display dynamically some content from Post you are viewing
    – If there is no content widget display header, widget title and empty box beneath.
    – In source code there is absolutely nothing, not even non-braking empty space. Only few pure div classes with nothing inside.

    Now, such problem i fixed with CSS3 and hide empty DIVs, but i need and have to have widget title, and it is making it impossible to hide with CSS3.

    Want to ask is it normal behaviour of WP ?
    And is there some code snippet to fix that ?

    Can say that it has nothing to do with PHP code inside widget. Tested with pure default text widget and empty widget shows.

    This one is quick and easy solution. But depending of subpage load widget can shows sometimes for a brief time.

    $(function() {
    $('.textwidget').each(function() {
        if ($.trim($(this).html()) == '')
            $(this).parents('#text-15').remove();
    });
});

    Small update, it it can help someone. Put this code in functions.php and use Discreet Text Widget instead of standard Text Widget.

    class HackadelicDiscreetTextWidget extends WP_Widget_Text
{
	function HackadelicDiscreetTextWidget() {
		$widget_ops = array('classname' => 'discreet_text_widget', 'description' => __('Arbitrary text or HTML, only shown if not empty'));
		$control_ops = array('width' => 400, 'height' => 350);
		$this->WP_Widget('discrete_text', __('Discreet Text'), $widget_ops, $control_ops);
	}

	function widget( $args, $instance ) {
		extract($args, EXTR_SKIP);
		$text = apply_filters( 'widget_text', $instance['text'] );
		if (empty($text)) return;
		$title = apply_filters('widget_title', empty($instance['title']) ? '' : $instance['title']);
		echo $before_widget;
		if ( !empty( $title ) ) { echo $before_title . $title . $after_title; } ?>
			<div class="textwidget"><?php echo $instance['filter'] ? wpautop($text) : $text; ?></div>
		<?php
		echo $after_widget;
	}
}

add_action('widgets_init', create_function('', 'return register_widget("HackadelicDiscreetTextWidget");'));

    Awesome, just what I was looking for… thank you!

    didn’t work with the create_function though, I just got an error of “class ‘WP_Widget_Text’ not found.” … seems it is trying to extend the class before it exists this way…

    so I just wrapped the class in a function and worked fine.

    function CreateHackadelicDiscreetTextWidget() {
class HackadelicDiscreetTextWidget extends WP_Widget_Text
{
	function HackadelicDiscreetTextWidget() {
		$widget_ops = array('classname' => 'discreet_text_widget', 'description' => __('Arbitrary text or HTML, only shown if not empty'));
		$control_ops = array('width' => 400, 'height' => 350);
		$this->WP_Widget('discrete_text', __('Discreet Text'), $widget_ops, $control_ops);
	}

	function widget( $args, $instance ) {
		extract($args, EXTR_SKIP);
		$text = apply_filters( 'widget_text', $instance['text'] );
		if (empty($text)) return;
		$title = apply_filters('widget_title', empty($instance['title']) ? '' : $instance['title']);
		echo $before_widget;
		if ( !empty( $title ) ) { echo $before_title . $title . $after_title; } ?>
			<div class="textwidget"><?php echo $instance['filter'] ? wpautop($text) : $text; ?></div>
		<?php
		echo $after_widget;
	}
}
return register_widget("HackadelicDiscreetTextWidget");
}

add_action('widgets_init', 'CreateHackadelicDiscreetTextWidget');

    Seems to me that WordPress could do this itself in not displaying all empty widgets anyway, not just text ones… ah well.

    Thanks.
    Why it is not in the WP core ? Human logic is “you dont have use of empty something, or nothing”.

    Almost like Ford public presentation with new car, and they say it is 100% guaranteed you will never drive this car, nor this car can have engine.
