Treimpose the limit, try using the 'post_limits' filter, or filter 'pre_option_posts_per_rss' and return -1
'posts_per_archive_page' => 10, //(int) - number of posts to show per page - on archive pages only. Over-rides showposts anposts_per_page on pages where is_archive() or is_search() would be true

'paged' => get_query_var('paged'), //(int) - number of page. Show the posts that would normally show up just on page X when usinthe "Older Entries" link.
//NOTE: Use get_query_var('page'); if you want your query to work in a Page template that you've set as your static front page. The query variable 'page' holds the pagenumber for a single paginated Post or Page that includes the <!--nextpage--> Quicktag in the post content.
'nopaging' => false, // (boolean) - show all posts or use pagination. Default value is 'false', use paging.
'posts_per_page' => 10, // (int) - number of post to show per page (available with Version 2.1, replaced showposts parameter). Use 'posts_per_page'=>-1 to show all posts (the 'offset' parameter is ignored with a -1 value). Set the 'paged' parameter if pagination is off after using this parameter.
//Note: if the query is in a feed, wordpress overwrites this parameter with the stored 'posts_per_rss' option. To reimpose the limit, try using the 'post_limits' filter, or filter 'pre_option_posts_per_rss' and return -1
'posts_per_archive_page' => 10, // (int) - number of posts to show per page - on archive pages only. Over-rides posts_per_page and showposts on pages where is_archive() or is_search() would be true.
'offset' => 3, // (int) - number of post to displace or pass over.
// Warning: Setting the offset parameter overrides/ignores the paged parameter and breaks pagination. for a workaround see: http://codex.wordpress.org/Making_Custom_Queries_using_Offset_and_Pagination
// The 'offset' parameter is ignored when 'posts_per_page'=>-1 (show all posts) is used.
'paged' => get_query_var('paged'), //(int) - number of page. Show the posts that would normally show up just on page X when usinthe "Older Entries" link.
//NOTE: This whole paging thing gets tricky. Some links to help you out:

// http://codex.wordpress.org/Pagination#Troubleshooting_Broken_Pagination
'page' => get_query_var('page'), // (int) - number of page for a static front page. Show the posts that would normally show up just on page X of a Static Front Page.

//'meta_value' - Note that a 'meta_key=keyname' must also be present in the query. Note alsthat the sorting will be alphabetical which is fine for strings (i.e. words), but can bunexpected for numbers (e.g. 1, 3, 34, 4, 56, 6, etc, rather than 1, 3, 4, 6, 34, 56 as yomight naturally expect).
//'meta_value_num' - Order by numeric meta value (available with Version 2.8). Also notthat a 'meta_key=keyname' must also be present in the query. This value allows for numericasorting as noted above in 'meta_value'.

Of course you would never use a query like this. It's just a comprehensive grouping for quick reference.
Also formatting in the github and raw view sucks. best to copy the raw and past in a code editor. I wrote this in SublimeText if that helps.
EDIT: Fixed formatting issues

You're missing the undocumented no_found_rows parameter. It takes a boolean value so I usually use true instead of 1 in this example: http://flavio.tordini.org/speed-up-wordpress-get_posts-and-query_posts-functions

Owner

Thanks Ryan, I added no_found_rows into the caching section at the bottom. If you think it belongs somewhere else I'm open to suggestions. Regarding using true/false vs 1/0 for booleans, is that just a preference or is there a best practice or other reason in there to choose one over the other?

Owner

Thanks Ryan, good call on writing out the keywords True/False. Makes a lot of sense. Will be updating the code shortly.

This is solid, thanks for posting!

It seems a the closing parenthesis for the whole array is missing on the 'tax_query' array

Owner

Thanks PotterSys, fixing now.
EDIT: Closed tax query array properly per PotterSys comment ^

Japh commented

Great reference, thanks! :)

Thanks for sharing!

First of all You did a great job compiling this in one file, congrats and thanks for it.
I have posted your work on my site http://updateox.com/wordpress/wp-query-quick-reference-with-all-its-parameters/ with all of your reference of course. I hope you won't mind it.

Owner

@rabinbiswas Thanks! Don't mind at all, nice to see others find it useful.

@luetkemj -- there is nothing better, IMHO, than a pathological example to know what's going on. The next thing would be comprehensive examples, but that would be a whole lot more work.

I did notice small error. Well, its theoretically correct, but probably isn't given what preceeds. In tag_slug__and and tag_slug__in have arrays of ints for their values but I think you want an array of strings.

Owner

@adsmart, that is def an error, thanks for the catch!

r-a-y commented

Nice! Just wanted to note that you're missing the 's' parameter for searching the post title and content.

More or less passing along the search from the query string ($s) into the query...

new WP_Query("s=$s&showposts=-1");

Owner

I didn't know about that one! Very interesting, will add it tomorrow.

Owner

Added "Search Parameter " section based on r-a-y and ryanduff's suggestions.

Great job, thanks for sharing!

Very handy reference. Good job.

I just noticed that WordPress treats the 'any' value for 'post_type' differently to other values. It is treated as a special "keyword" and it cannot be in an array e.g.

$my_query = new WP_Query(array('post_type' => array('post'))); // Works
$my_query = new WP_Query(array('post_type' => array('post','page'))); // Works
$my_query = new WP_Query(array('post_type' => array('any'))); // Does not work
$my_query = new WP_Query(array('post_type' => 'any')); // Works

I think it would be worth updating this gist to reflect that.
cheers
/Eoin/

Owner

@eoinkelly
Very interesting, thanks for the catch, Gist has been updated.

thank you for this

Thanks.

I would like you to add this if you don't mind.
with :]-> 's' => $s
compare is very useful
[{ compare (string) - Operator to test. Possible values are '=', '!=', '>', '>=', '<', '<=', 'LIKE', 'NOT LIKE', 'IN', 'NOT IN', 'BETWEEN', 'NOT BETWEEN'. Default value is '='.}]

And also sentence is very useful if we want users to search for exact words (like "why search for exact words") if we use sentence = true then wordpress will search the whole sentence & depending upon the compare parameter. But if we don't use sentence parameter wordpress will split each word and search for each word in database depending upon the compare.

I hope my comment makes sense to you. I am not good with words though ;)

Owner

@saas786

Thanks for these! Will take a closer look on monday and add them.

Owner

@saas786

I added the additions you mentioned. Please review and let me know if they are accurate. From some research I found an old post that mentions an "exact" flag as well: http://wordpress.org/support/topic/how-to-search-phrases

I didn't add this as it seems that you could do the same thing with the compare parameters. Have you used "exact" before? Currently I'm leaning towards not including it here.

@luetkemj

Thanks for adding it. Yes "exact" flag / parameter is correct. @Otto is an experienced guy, so his comments are valid. I further explored it and found that compare has no impact on search query instead exact is used for comparison.

//////Search Parameter
's' => $s,

'exact' => true // if set to true then search will be like "LIKE 'search_term')" if set to false then it will be like "LIKE '%ssearch_term%s')"
'sentance' => true

you can remove the compare parameter from the list and I found no impact on query (I thought it was the compare parameter that made impact on my search query, but instead it was "exact" flag / parameter.

Thanks.

Thanks for checking up on that, I didn't have time this morning to do an actual test. I have used a mix of the verbiage from you, myself, and Otto as well a link to the comments here for more info.

You are a good man, luetkemj.

Thanks @cam5 :)

Epic

Something I had to do today - Mix/Match Orderby:

Sort a custom post type (people) by last name (by default) or by menu_order (when the posts have a menu order entered).
The title field is always lastnamef, which made me think I could do this:
'orderby' => 'menu_order title',
It doesn't seem to work consistently for my custom post type.

But from this post:
http://wordpress.org/support/topic/order-by-slug-not-work
And from this post:
http://wordpress.stackexchange.com/questions/2969/order-by-menu-order-and-title

I deduced this - which does work:
'orderby' => 'menu_order name',

Might be worth adding.

@charlietriplett, This is really interesting! Do you know if it works to just mix and match any of the orderby options?

This should definitely be added but I want to play around with it first to get a good idea on how to document it.

Thanks!

I don't — and I don't understand why 'menu_order title' isn't just as consistent. Hrmm … But a very useful tool for sorting posts/pages. I'll be incorporating it into some automated child-nav features as well where some degree of custom ordering is desirable.

//NOTE: You should set get_query_var( 'page' ); if you want your query to work with pagination. Since Wordpress 3.0.2, you dget_query_var( 'page' ) instead of get_query_var( 'paged' ). The pagination parameter 'paged' for WP_Query() remains the same.

This is only true for a paginated single post/page and for static front page pagination. I've updated the codex with this information here:
http://codex.wordpress.org/Function_Reference/WP_Query#Pagination_Parameters

Was the codex wrong or did something change recently?

Owner

Thanks @keesiemeijer, I've actually been having issues pagination myself lately so this may be the problem. Gist has been updated.

Is there any way to sort by meta_key where the meta_value contains date string in the format mm-dd-yyyy.

@luetkemj 'author' => 1,2,3, should be 'author' => '1,2,3',

'orderby' can now take 'post__in'.

Thank you very much for all your help and useful

great post ;)

You make my day.
And not only this one..
This gist is very helpful.

Thanks a lot @luetkemj

Just used 'post_parent' for the first time, to return child pages. It turns out you must also set 'post_type" => 'page' before it works. That is not well documented. It would be helpful to add that to the 'post_parent' comments.

Is there a typo on line 168 - should "sentance" be "sentence"?
Thanks for the guide - it's exactly what I've being looking for.

Owner

Gist updated.

Thanks to @charlietriplett, @wpsmith, and @stvwlf for keeping an eye on this thing.

If anyone notices anything I've missed or things that have been added since 3.5 let me know so I can keep this up to date!

Perhaps I'm overlooking it, but the meta_query array accepts a 'relation' key which can have a value of either 'AND' or 'OR'.

I want make relation between post query and meta query "OR". like post_type = "post" OR (meta_key = "key" AND meta_value = "value") so how can I do that please help me out

@manifestcreative You're correct. In class WP_Meta_Query::__construct, a check for $meta_query['relation'] is made. AND is the default if none is set. The options are AND and OR.

@luetkemj, I must say I'm your number one fan, this page is one of my most consulted. Thanks a lot!!!

this link (line 173)
//Not sure what these do. For more info see: http://codex.wordpress.org/Class_Reference/WP_Query#Post_Field_Parameters

should be changed to this
http://codex.wordpress.org/Class_Reference/WP_Query#Return_Fields_Parameter

What it does is it changes the format of returned result. Say, you can pass 'fields' => 'ids' and it will return just IDs of matching posts.

Owner

Bunch of updates per @manifestcreative and @Dimasmagadan comments. Thanks!

Owner

Tons of new updates. Bringing the query up to date with things added in 3.5, 3.7, and 3.9.

Holy wow, I was slacking... sorry about that.

the line 'category_name' => 'staff', 'news', is invalid. Should just be one of those or an array, right?

Owner

@sephelps - yep! that was busted. But it is supposed to be a string. You can display posts that have any of the named categories if you wrap the whole thing in a string, commas and all.

Alternately you can display posts that have "all" of the categories if you use a "+" instead of a ","

'staff,news' or 'staff+news',

Gist has been updated.
See this page for more details on the above:
http://codex.wordpress.org/Class_Reference/WP_Query#Category_Parameters

thanks so much
