Problems adding and removing sidebars.

    I am developing a website with over 40 sidebars at this moment. I want to keep my sidebars in alphabetical order in the widgets.php page so that my client will be able to find the correct sidebar with ease. I’m finding that when I add a new sidebar (say in the middle of my sidebar list) in the functions.php page and upload it to my server, the content that was already on the existing sidebars (listed in functions.php below the new sidebar) will be erased.

    So, if I want to add a new sidebar, I’m forced to place it at the bottom of the sidebar list in functions.php so that my existing content doesn’t get erased. I’m also realizing that if I want to remove a sidebar from the list in functions.php it’s going to erase the content in the existing sidebars.

    Here is my code in fuctions. php

    <?php
if ( function_exists('register_sidebars') )

      the_permalink();
      echo "'>"."Read More &rarr;</a>";
      echo "</p>";
   }
}

?>

    How do I resolve my dilemma?

  • The key here is that if you do not provide an ID to your sidebars, things start to go haywire. Rather than going crazy with code there, you can also do something like this:

    // this initializes the blog/left sidebars because they're special
if ( function_exists('register_sidebar') ) {
    register_sidebar(array(
    	'name' => 'Blog Left',
    	'id' => '10000',
        'before_widget' => '',
        'after_widget' => '<hr class="blue-hr" />',
        'before_title' => '<h3 class="widgettitle">',
        'after_title' => '</h3>',));
	}
if ( function_exists('register_sidebar') ) {
    register_sidebar(array(
    	'name' => 'Blog Right',
    	'id' => '20000',
        'before_widget' => '',
        'after_widget' => '<hr class="blue-hr" />',
        'before_title' => '<h3 class="widgettitle">',
        'after_title' => '</h3>',));
	}

// this grabs all pages, and gives them a sidebar. crazy, but it works. the sidebar-id is set to the page-id, so there should be no issues
$pages_with_sidebar = get_pages();
foreach($pages_with_sidebar as $page_honk)
{
	if ($page_honk->post_parent != 0) {
		$page_honk->post_title = "- " . $page_honk->post_title;
	}
	if ( function_exists('register_sidebar') ) {
	    register_sidebar(array(
	    	'name' => $page_honk->post_title,
			'id' => $page_honk->ID,
	        'before_widget' => '',
	        'after_widget' => '<hr class="blue-hr" />',
	        'before_title' => '<h3 class="widgettitle">',
	        'after_title' => '</h3>',));
		}
}

    This will generate a sidebar for every Page, and will even mark Sub-pages with an indented dash. Not sure if this helps you out at all, but this might help others trying to find a way to have many many sidebars!

    What code would you need in each page to call these sidebars?

    <?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('NAME OF SIDEBAR AS DESIGNATED IN FUNCTIONS.PHP') ) ?>

    Put that code wherever you want to call on the sidebar

    The missing piece to make this all automatic is to call the sidebar by current page id:

    if ( is_page() ) {
	$id = get_the_ID();
	$id = ('"' .$id. '"');
	dynamic_sidebar($id);
	} else {
	dynamic_sidebar('Sidebar'); }

    No fuss sidebars for all pages now!

    Another idea… so as not to have to maintain every sidebar, check if sidebar actually has content and if not, display a default one.

    <?php if ( is_page() ) {
	$id = get_the_ID();
	$id = ('"' .$id. '"');
	$stuff = dynamic_sidebar($id);
	if ( $stuff == null ) { dynamic_sidebar('Page Sidebar'); }
	} else {
	dynamic_sidebar('Blog Sidebar');
	 } ?>

    Sorry for the ugly code. Graphic designers strike again.

    And the moral of the story… add a page or delete a page and you lose all your sidebar data if you use my suggestion above. Net contribution = 0
    Sorry.
