How to: Limiting the posts in you archive widget

Published

on

I have show you how to create a custom widget in a previous post. But how about adding and additional “Archives” widget that won’t list the last 3 years (if you’ve been around that long) in month form stretching down your whole sidebar?

Well, lets take a look at the original code found in the widgets.php file in the ./wp-includes/ folder.

<?php

/**
* Display archives widget.
*
* @since 2.2.0
*
* @param array $args Widget arguments.
*/
function wp_widget_archives($args) {
extract($args);
$options = get_option('widget_archives');
$c = $options['count'] ? '1' : '0';
$d = $options['dropdown'] ? '1' : '0';
$title = empty($options['title']) ? __('Archives') : apply_filters('widget_title', $options['title']);

echo $before_widget;
echo $before_title . $title . $after_title;

if($d) {
?>
<select name="archive-dropdown" onchange='document.location.href=this.options[this.selectedIndex].value;'> <option value=""><?php echo attribute_escape(__('Select Month')); ?></option> <?php wp_get_archives("type=monthly&format=option&show_post_count=$c"); ?> </select>
<?php
} else {
?>
<ul>
<?php wp_get_archives("type=monthly&show_post_count=$c"); ?>
</ul>
<?php
}

echo $after_widget;
}

/**
* Display and process archives widget options form.
*
* @since 2.2.0
*/
function wp_widget_archives_control() {
$options = $newoptions = get_option('widget_archives');
if ( isset($_POST["archives-submit"]) ) {
$newoptions['count'] = isset($_POST['archives-count']);
$newoptions['dropdown'] = isset($_POST['archives-dropdown']);
$newoptions['title'] = strip_tags(stripslashes($_POST["archives-title"]));
}
if ( $options != $newoptions ) {
$options = $newoptions;
update_option('widget_archives', $options);
}
$count = $options['count'] ? 'checked="checked"' : '';
$dropdown = $options['dropdown'] ? 'checked="checked"' : '';
$title = attribute_escape($options['title']);
?>
<p><label for="archives-title"><?php _e('Title:'); ?> <input class="widefat" id="archives-title" name="archives-title" type="text" value="<?php echo $title; ?>" /></label></p>
<p>
<label for="archives-count"><input class="checkbox" type="checkbox" <?php echo $count; ?> id="archives-count" name="archives-count" /> <?php _e('Show post counts'); ?></label>
<br />
<label for="archives-dropdown"><input class="checkbox" type="checkbox" <?php echo $dropdown; ?> id="archives-dropdown" name="archives-dropdown" /> <?php _e('Display as a drop down'); ?></label>
</p>
<input type="hidden" id="archives-submit" name="archives-submit" value="1" />
<?php } ?>

Simple enough? Or not..

Anyway lets just add on and change a few things. Then will add the final code to your functions.php file.

Okay, starting with the first function: wp_widget_archive and rename to widget_archive_limit

Should look like this now:

function widget_archives_limit($args) {

Then under the this line:

$title = empty($options['title']) ? __('Archives') : apply_filters('widget_title', $options['title']);

Add:

$limit = empty($options['limit']) ? __('Limit') : apply_filters('widget_limit', $options['limit']);

At this line:

<?php wp_get_archives("type=monthly&format=option&show_post_count=$c&limit=$limit"); ?>

We have added in &limit=$limit. The same goes for the second wp_get_archives:

<?php wp_get_archives("type=monthly&show_post_count=$c&limit=$limit"); ?>

At the end of this code add:

wp_register_sidebar_widget('archives limit', __('Archives Limit'), 'widget_archives_limit', $widget_ops);

The whole code should look like this:

function widget_archives_limit($args) {
	extract($args);
	$options = get_option('widget_archives');
	$c = $options['count'] ? '1' : '0';
	$d = $options['dropdown'] ? '1' : '0';
	$title = empty($options['title']) ? __('Archives') : apply_filters('widget_title', $options['title']);
	$limit = empty($options['limit']) ? __('Limit') : apply_filters('widget_limit', $options['limit']);

	echo $before_widget;
	echo $before_title . $title . $after_title;

	if($d) {
?>
		<select name="archive-dropdown" onchange='document.location.href=this.options[this.selectedIndex].value;'> <option value=""><?php echo attribute_escape(__('Select Month')); ?></option> <?php wp_get_archives("type=monthly&format=option&show_post_count=$c&limit=$limit"); ?> </select>
<?php
	} else {
?>
		<ul>
		<?php wp_get_archives("type=monthly&show_post_count=$c&limit=$limit"); ?>
		</ul>
<?php
	}

	echo $after_widget;
}

wp_register_sidebar_widget('archives limit', __('Archives Limit'), 'widget_archives_limit', $widget_ops);

That takes care of the widget its self, now we need to create the controls. Once again find the second function and change wp_widget_archive_control to widget_archives_limit_control

Find this line:

$newoptions['title'] = strip_tags(stripslashes($_POST["archives-title"]));

and add this line below:

$newoptions['limit'] = strip_tags(stripslashes($_POST["archives-limit"]));

Then find this line:

$title = attribute_escape($options['title']);

and add this line below:

$limit = attribute_escape($options['limit']);

Finally look for this line:

<label for="archives-dropdown"><input class="checkbox" type="checkbox" <?php echo $dropdown; ?> id="archives-dropdown" name="archives-dropdown" /> <?php _e('Display as a drop down'); ?></label>
			</p>

and add this line below:

<p><label for="archives-limit"><?php _e('Limit (enter a number):'); ?> <input class="widefat" id="archives-limit" name="archives-limit" type="text" value="<?php echo $limit; ?>" /></label></p>

then register the widget controls:

wp_register_widget_control('archives limit', __('Archives Limit'), 'widget_archives_limit_control' );

The code should look like this:

function widget_archives_limit_control() {
	$options = $newoptions = get_option('widget_archives');
	if ( isset($_POST["archives-submit"]) ) {
		$newoptions['count'] = isset($_POST['archives-count']);
		$newoptions['dropdown'] = isset($_POST['archives-dropdown']);
		$newoptions['title'] = strip_tags(stripslashes($_POST["archives-title"]));
		$newoptions['limit'] = strip_tags(stripslashes($_POST["archives-limit"]));
	}
	if ( $options != $newoptions ) {
		$options = $newoptions;
		update_option('widget_archives', $options);
	}
	$count = $options['count'] ? 'checked="checked"' : '';
	$dropdown = $options['dropdown'] ? 'checked="checked"' : '';
	$title = attribute_escape($options['title']);
	$limit = attribute_escape($options['limit']);
?>
			<p><label for="archives-title"><?php _e('Title:'); ?> <input class="widefat" id="archives-title" name="archives-title" type="text" value="<?php echo $title; ?>" /></label></p>
			<p>
				<label for="archives-count"><input class="checkbox" type="checkbox" <?php echo $count; ?> id="archives-count" name="archives-count" /> <?php _e('Show post counts'); ?></label>
				<br />
				<label for="archives-dropdown"><input class="checkbox" type="checkbox" <?php echo $dropdown; ?> id="archives-dropdown" name="archives-dropdown" /> <?php _e('Display as a drop down'); ?></label>
			</p>
			<p><label for="archives-limit"><?php _e('Limit (enter a number):'); ?> <input class="widefat" id="archives-limit" name="archives-limit" type="text" value="<?php echo $limit; ?>" /></label></p>
			<input type="hidden" id="archives-submit" name="archives-submit" value="1" />
<?php } 

wp_register_widget_control('archives limit', __('Archives Limit'), 'widget_archives_limit_control' );

The final code:

/**
 * Display archives widget.
 *
 * @since 2.2.0
 *
 * @param array $args Widget arguments.
 */
function widget_archives_limit($args) {
	extract($args);
	$options = get_option('widget_archives');
	$c = $options['count'] ? '1' : '0';
	$d = $options['dropdown'] ? '1' : '0';
	$title = empty($options['title']) ? __('Archives') : apply_filters('widget_title', $options['title']);
	$limit = empty($options['limit']) ? __('Limit') : apply_filters('widget_limit', $options['limit']);

	echo $before_widget;
	echo $before_title . $title . $after_title;

	if($d) {
?>
		<select name="archive-dropdown" onchange='document.location.href=this.options[this.selectedIndex].value;'> <option value=""><?php echo attribute_escape(__('Select Month')); ?></option> <?php wp_get_archives("type=monthly&format=option&show_post_count=$c&limit=$limit"); ?> </select>
<?php
	} else {
?>
		<ul>
		<?php wp_get_archives("type=monthly&show_post_count=$c&limit=$limit"); ?>
		</ul>
<?php
	}

	echo $after_widget;
}

wp_register_sidebar_widget('archives limit', __('Archives Limit'), 'widget_archives_limit', $widget_ops);

/**
 * Display and process archives widget options form.
 *
 * @since 2.2.0
 */
function widget_archives_limit_control() {
	$options = $newoptions = get_option('widget_archives');
	if ( isset($_POST["archives-submit"]) ) {
		$newoptions['count'] = isset($_POST['archives-count']);
		$newoptions['dropdown'] = isset($_POST['archives-dropdown']);
		$newoptions['title'] = strip_tags(stripslashes($_POST["archives-title"]));
		$newoptions['limit'] = strip_tags(stripslashes($_POST["archives-limit"]));
	}
	if ( $options != $newoptions ) {
		$options = $newoptions;
		update_option('widget_archives', $options);
	}
	$count = $options['count'] ? 'checked="checked"' : '';
	$dropdown = $options['dropdown'] ? 'checked="checked"' : '';
	$title = attribute_escape($options['title']);
	$limit = attribute_escape($options['limit']);
?>

wp_register_widget_control('archives limit', __('Archives Limit'), 'widget_archives_limit_control' );

WordPress Beta 3 Error

Published

WordPress Beta 3 Error 4

If you don’t know, this site is running the latest WordPress. Which is in Beta testing, version 2.7 Beta-3.

I installed a new plugin today: SEO Smart Links. And as soon as I installed and tested it out, I get an error message on my dashboard.

The funny thing is, usually when there is an error, it shows up at the top of the page, before the site loads. This error is showing up at the bottom of the site.

huh, I was going to past the code error, but it seemed to disappear? I will post it if it shows up again.

Table of Contents

OH…

Another big error is clicking the publish button. Seems that I keep getting an Error 500 – Internal server error when publishing a post or re-saving a post. 🙁

Update

I used my handy dandy Plugin: WP-DBManager to restore my backup from yesterday. Fixed both problems!
Hopefully, Vladimir Prelovac will update his plugin for WordPress 2.7 use.

Update 2

Upon further inspection, and trials. This plugin is awesome and powerful for how simple it is. But my plugin: OIO Publisherseems not to like ALOT of my plugins I have installed.

So check out the SEO plugin for sure!
