display-categories-widget's Issues

Still displays title HTML tag even if title is actually empty

In line 213, variable $title is defined like so :

$title = empty($instance['title']) ? ' ' : apply_filters('widget_title', $instance['title']);

So $title is never actually empty (there's at least one space).

And then, in line 228, it checks $title and therefore always displays a heading tag :

if (!empty($title)) echo $before_title . $title . $after_title;

I believe you should leave $title as an empty string if none is provided.

Feature request: add links to title

Great plugin, so useful for me.

I currently use it to list post categories in 4 columns, using 4 separate widgets.
It displays the title of the parent category, followed by the list of sub categories (1 level only), and that's exactly what I needed.

There's just one more thing I need : could we have the possibility to have a link on the parent category? Right now I don't think this is possible, it justs displays the title within a H2 tag.

Thanks

Removing Deprecated Constructor Method

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; DisplayCategoriesWidget has a deprecated constructor in /vagrant/web/wp-content/plugins/display-categories-widget/display_categories_widget.php on line 12

suggestion: age limit for posts

Maybe a simple and nice feature to add is the possibility of setting an age limit for the displayed posts. For example, this would allow to display a "hot news" category that would indeed contain only brand new information.

However, as a php/wordpress newbee, I am not the most efficient person for this task. If anybody has the strength to solve this quickly, I would be very grateful.

Issue With "??" in Line 214 (Solved)

Just replace the code from line 214 until 226:

$cat_id = $instance['category'] ?? 0;
$dcw_limit = $instance['dcw_limit'] ?? 'Categories';
$dcw_option_name = $instance['dcw_option_name'] ?? '';
$dcw_exclude = $instance['dcw_exclude'] ?? '';
$dcw_depth = $instance['dcw_depth'] ?? 0;
$display_empty_categories = $instance['display_empty_categories'] ?? 0;
$showcount_value = $instance['showcount_value'] ?? 0;
$use_desc_for_title = $instance['use_desc_for_title'] ?? 0;
$sort_order_by = $instance['sort_order_by'] ?? 'name';
$sort_order_as = $instance['sort_order_as'] ?? 'ASC';
$show_format = $instance['show_format'] ?? 0;
$dcw_column = $instance['dcw_column'] ?? 1;
$dcw_display_parent = $instance['display_parent'] ?? 0;

Replace to this:

$cat_id = $instance['category'] ? $instance['category'] : 0;
$dcw_limit = $instance['dcw_limit'] ? $instance['dcw_limit'] : 'Categories';
$dcw_option_name = $instance['dcw_option_name'] ? $instance['dcw_option_name'] : '';
$dcw_exclude = $instance['dcw_exclude'] ? $instance['dcw_exclude'] : '';
$dcw_depth = $instance['dcw_depth'] ? $instance['dcw_depth'] : 0;
$display_empty_categories = $instance['display_empty_categories'] ? $instance['display_empty_categories'] : 0;
$showcount_value = $instance['showcount_value'] ? $instance['showcount_value'] : 0;
$use_desc_for_title = $instance['use_desc_for_title'] ? $instance['use_desc_for_title'] : 0;
$sort_order_by = $instance['sort_order_by'] ? $instance['sort_order_by'] : 'name';
$sort_order_as = $instance['sort_order_as'] ? $instance['sort_order_as'] : 'ASC';
$show_format = $instance['show_format'] ? $instance['show_format'] : 0;
$dcw_column = $instance['dcw_column'] ? $instance['dcw_column'] : 1;
$dcw_display_parent = $instance['display_parent'] ? $instance['display_parent'] : 0;

Issue with Style in Line 238 (Solved)

For this issue the float style makes the categories layout overflow, so I just remove the style because it's not necessary at all:

echo "<style>.dcw_c1 {float:left; width:100%} .dcw_c2 {float:left; width:50%} .dcw_c3 {float:left; width:33%}</style>";
echo "<ul class='dcw'>";
wp_list_categories('orderby='.$sort_order_by.'&order='.$sort_order_as.'&use_desc_for_title='.$use_desc_for_title.'&show_count=' . $showcount_value . '&child_of=' . $cat_id . '&hide_empty=' . $display_empty_categories . '&title_li=&number=' . $dcw_limit . '&exclude=' . $dcw_exclude . '&depth=' . $dcw_depth);
echo "</ul>";
$class_definer = "dcw_c" . $dcw_column;
echo "<script>jQuery('ul.dcw').find('li').addClass('$class_definer');</script>";

Replace to:

// echo "<style>.dcw_c1 {float:left; width:100%} .dcw_c2 {float:left; width:50%} .dcw_c3 {float:left; width:33%}</style>";
echo "<ul class='dcw'>";
wp_list_categories('orderby='.$sort_order_by.'&order='.$sort_order_as.'&use_desc_for_title='.$use_desc_for_title.'&show_count=' . $showcount_value . '&child_of=' . $cat_id . '&hide_empty=' . $display_empty_categories . '&title_li=&number=' . $dcw_limit . '&exclude=' . $dcw_exclude . '&depth=' . $dcw_depth);
echo "</ul>";
// $class_definer = "dcw_c" . $dcw_column;
// echo "<script>jQuery('ul.dcw').find('li').addClass('$class_definer');</script>";

I just comment the code that not functional for me.
