Frequently Asked Questions

How can I exclude categories?

List its ID as a negative number.

My site broke after customizing the excerpt. What happened?

Did you set the strip_tags attribute to false? ([excerpt strip_tags=0]). If tags haven't been stripped, it may have cut off the text before an HTML tag was properly closed, thus breaking the page. Setting strip_tags to false should only be used if you're carefully managing the excerpt's output.

Why can't I add an ID to the element in 'Before Items'?

There are limitations on the tag or tag/attribute combiniations allowed by WordPress. However, these can be overcome with a few lines of code.

To allow an additional tag, use this:

add_filter( "admin_init", "allowed_tags" );
function allowed_tags() {
	global $allowedposttags;
	$allowedposttags["video"] = array();
}

To allow additional attributes for any tag, use the following code:

add_filter( "admin_init", "allowed_tags" );
function allowed_tags() {
	global $allowedposttags;
	$allowedposttags["video"]["src"] = array();
	$allowedposttags["video"]["type"] = array();
	$allowedposttags["video"]["poster"] = array();
}

If you're using a custom theme, you can add this code the its functions.php file. Otherwise, you may want to create your own plugin to hold these modifications.

See this post for instructions on creating your own plugin.

Other Notes

Explanation of options:

Widget Display

Title: Your recent posts widget's title on your sidebar. Default: Recent Posts [miniloop title="Recent Posts"] get_miniloops( array('title' => 'Recent Posts' ) );

Title URL: The page the title should link to. Default: none [miniloop title_url="/blog/"] get_miniloops( array('title_url' => '/blog/'' ) );

Building the Query

Number of Posts: Number of posts to be displayed. Default: 3 [miniloop number_posts=3] get_miniloops( array('number_posts' => 3 ) );

Post Offset: Number of posts to skip before displaying the list. Default: 0 [miniloop post_offset=0] get_miniloops( array('post_offset' => 0 ) );

Maximum Age: Don't show posts more than X days old Default: 0 [miniloop maximum_age=0] get_miniloops( array('maximum_age' => 0 ) );

Post Author: Get author's post. By ID. Default: none [miniloop post_author=0] get_miniloops( array('post_author' => 0 ) );

Post Type: Post type to display. Default: post [miniloop post_type=post] get_miniloops( array('post_type' => 'post' ) );

Post Status: Post status to display. Primarily useful to show upcoming (future) posts. But be creative! Default: publish [miniloop post_status=publish] get_miniloops( array('post_status' => 'publish' ) );

Order By: What order the posts should be displayed in. Default: date [miniloop order_by=date] get_miniloops( array('order_by' => 'date' ) );

Order: Ascending (good for order by title) or Descending (good for order by date) Default: DESC [miniloop order=DESC] get_miniloops( array('order' => 'DESC' ) );

Ordering by the values of some_key (works well if the values of some_key are strings/words): [miniloop order_by=meta_value order_meta_key=some_key] get_miniloops( array('order_by' => 'meta_value', 'order_meta_key' => 'some_key' ) );

Ordering by the numeric values of some_key (works well if the values of some_key are numbers/integers): [miniloop order_by=meta_value_num order_meta_key=some_key] get_miniloops( array('order_by' => 'meta_value_num', 'order_meta_key' => 'some_key' ) );

Show posts in reverse order? Perhaps you want the 3 most recent posts, but you want the oldest of those to be displayed first. If so, check this. Default: 0 [miniloop reverse_order=0] get_miniloops( array('reverse_order' => 0 ) );

Shuffle post order? Shuffle the order of the posts matching your query. Perhaps showing the 5 most recent posts in randomized order. Default: 0 [miniloop shuffle_order=0] get_miniloops( array('shuffle_order' => 0 ) );

Ignore sticky posts? Treat sticky posts as normal posts. I recommend ignoring, or the number of posts displayed may be inconsistent. Default: 1 [miniloop ignore_sticky=1] get_miniloops( array('ignore_sticky' => 1 ) );

Exclude sticky posts? Don't show sticky posts at all. Default: 0 [miniloop exclude_sticky=0] get_miniloops( array('exclude_sticky' => 0 ) );

Only sticky posts? Show only sticky posts. Default: 0 [miniloop only_sticky=0] get_miniloops( array('only_sticky' => 0 ) );

If viewing a single post, exclude it? If viewing a single post, remove it from the widget display. Default: 1 [miniloop exclude_current=1] get_miniloops( array('exclude_current' => 1 ) );

Get posts from current category (if archive)? If viewing an archive, only show posts from the same category. Default: 0 [miniloop current_category=1] get_miniloops( array('current_category' => 1 ) );

Get posts from first category (if single)? If viewing a single post, only show posts from the first category. Default: none [miniloop current_single_category=1] get_miniloops( array('current_single_category' => 1 ) );

Get posts from current author (if single or archive)? Show more posts from the current author. Default: none [miniloop current_author=1] get_miniloops( array('current_author' => 1 ) );

Categories: Comma separated list of category IDs to pull from. Use negative ID numbers to exclude a category. Default: none [miniloop categories="1,8,13"] get_miniloops( array('categories' => '1,8,13' ) );

Tags: Comma separated list of tag IDs to pull from. Use negative ID numbers to exclude a tag. Default: none [miniloop tags="15,40,88"] get_miniloops( array('tags' => '15,40,88' ) );

Custom Taxonomies: A clunky way to support custom taxonomies. Default: none. To include terms 5, 6, 9 from taxonomy "Genre" do this: [miniloop tax="genre=5,6,9"] get_miniloops( array('tax' => 'genre=5,6,9' ) );

Custom Fields: For listing posts that have certain meta data. Default: none. To list posts that have a custom field 'favorite_color' with a value of 'blue' do this: [miniloop custom_fields="favorite_color=blue"] get_miniloops( array('custom_fields' => 'favorite_color=blue' ) );

Exclude Posts: A comma separated list of post IDs to exclude. Default: none [miniloop exclude="15,200,1032"] get_miniloops( array('exclude' => '15,200,1032' ) );

Display

Before Items: Text/HTML to insert before the post list. Default: <ul> [miniloop before_items="<div>"] get_miniloops( array('before_items' => '<div>' ) );

After Items: Text/HTML to insert after the post list. Default: </ul> [miniloop after_items="</div>"] get_miniloops( array('after_items' => '</div>' ) );

Item Format: HTML and shortcodes to format each item

Template Tag

use miniloops( $args ) or get_miniloops( $args )

Like WordPress function, the 'get_' variant will simply return the results.

Here are the acceptable arguments and their default values:

$args = array(
		'title' => __( 'Recent Posts', 'mini-loops' ),
		'hide_title' => 0,
		'title_url' => '',
		'number_posts' => 3,
		'post_offset' => 0,
		'post_type' => 'post',
		'post_status' => 'publish',
		'order_by' => 'date',
		'order' => 'DESC',
		'reverse_order' => 0,
		'shuffle_order' => 0,
		'ignore_sticky' => 1,
		'only_sticky' => 0,
		'exclude_current' => 1,
		'categories' => '',
		'tags' => '',
		'tax' => '',
		'custom_fields' => '',
		'exclude' => '',
		'before_items' => '<ul>',
		'item_format' => '<li><a href="[url]">[title]</a><br />[excerpt]</li>',
		'after_items' => '</ul>',
		);
get_miniloops( $args );

Shortcode

[miniloop]

Use with all args listed above e.g. [miniloop number_posts=10]

Exception - 'item_format' must be handled differently

New way (since v0.9):

Create a custom field named ml_format and save the item format there. Then adjust your [miniloop] shortcode e.g. [miniloop number_posts=10][ml_format][/miniloop]

If needed, you can change the custom field. Just pass the name of the new custom field to the [ml_format] shortcode e.g. [miniloop number_posts=10][ml_format name="new_field"][/miniloop]

Old way:

'item_format' must go into the content of the shortcode, and square brackets must be replaced with curly brackets. e.g. [miniloop number_posts=10]{title}by {author}<br />[/miniloop]

Also, if you are using html inside the item_format, you must add this into the HTML editor, else your markup will be rendered, not parsed
