Adding a div to wrap widget content after the widget title

Question

I'm trying to add a div to widget's content in my dynamic sidebar.

Here is the register code;

register_sidebar(array(
        'name' => "Sidebar1",
        'id' => 'home-sidebar-1',
        'before_widget' => '<div class="sidebar-box">',
        'after_widget' => '</div>',
        'before_title' => '<div class="title">',
        'after_title' => '</div>',
    ));

But this code causes like this;

<div class="sidebar-box">
    <div class="title">{WIDGET TITLE}</div>
     {WIDGET CINTENT}
</div>

Here is what i trying to do;

<div class="sidebar-box">
    <div class="title">{WIDGET TITLE}</div>
    <div class="content">
           {WIDGET CINTENT}
    </div> 
</div>

How it can be done?

Answer 1

In addition to Toscho's answer here's what you need for a robust solution:

// if no title then add widget content wrapper to before widget
add_filter( 'dynamic_sidebar_params', 'check_sidebar_params' );
function check_sidebar_params( $params ) {
    global $wp_registered_widgets;

    $settings_getter = $wp_registered_widgets[ $params[0]['widget_id'] ]['callback'][0];
    $settings = $settings_getter->get_settings();
    $settings = $settings[ $params[1]['number'] ];

    if ( $params[0][ 'after_widget' ] == '</div></div>' && isset( $settings[ 'title' ] ) && empty( $settings[ 'title' ] ) )
        $params[0][ 'before_widget' ] .= '<div class="content">';

    return $params;
}

From Toscho's answer:

register_sidebar(array(
    'name' => "Sidebar1",
    'id' => 'home-sidebar-1',
    'before_widget' => '<div class="sidebar-box">',
    'after_widget' => '</div></div>',
    'before_title' => '<div class="title">',
    'after_title' => '</div><div class="content">',
));

What this does is:

• checks the settings for the registered sidebar for widgets ending in 2 closing <div>s
• checks if there's no title
• if not, it modifies the before_widget output to show the opening widget content div

You could use this approach to change the sidebar arguments in other ways to based on the widget instance's settings.

Add the second div to the title parameter:

register_sidebar(array(
        'name' => "Sidebar1",
        'id' => 'home-sidebar-1',
        'before_widget' => '<div class="sidebar-box">',
        'after_widget' => '</div></div>',
        'before_title' => '<div class="title">',
        'after_title' => '</div><div class="content">',
    ));
