Obdobný jako předchozí, menu ale zůstává vlevo jako vertikální. Oproti předchozímu umožňuje customizaci přihlašovací stránky.

Cache pro zrychlení WP a menší zátěž serveru

Simple Cache
https://wordpress.org/plugins/simple-cache/

Simple Cache was constructed after getting frustrated with the major caching plugins available and building sites with developer-only complex caching solutions that get millions of page views per day. Simple Cache promises the following:

– Extremely simple one-click install. There is an on-off switch. That’s it. No need to wade through 50 complicated settings.
– Simple Cache makes your site run very fast so you can handle lots of traffic.
– Extremely easy to delete. Don’t like the plugin? You can remove it, and your website won’t break.
– Easily clear the cache if you need to.
– Enable gzip compression

DB Cache Reloaded Fix
http://wordpress.org/extend/plugins/db-cache-reloaded-fix/

The fastest cache engine for WordPress, that produces cache of database queries with easy configuration. Compatible with WordPress 3.1
This plugin caches every database query with given lifetime. It is much faster than other html caching plugins and uses less disk space for caching. Now compatible with WordPress 3.1. This plugin is based on DB Cache Reloaded by sirzooro and patched so it have WordPress 3.1 compatibility.

I think you’ve heard of WP-Cache or WP Super Cache, they are both top plugins for WordPress, which make your site faster and responsive. Forget about them – with DB Cache Reloaded your site will work much faster and will use less disk space for cached files.

W3 Total Cache
http://wordpress.org/extend/plugins/w3-total-cache/
http://www.w3-edge.com/wordpress-plugins/w3-total-cache/

The fastest and most complete WordPress performance optimization plugin. Trusted by many popular sites like: mashable.com, smashingmagazine.com, makeuseof.com, kiss925.com, lockergnome.com, tutsplus.com, johnchow.com, ilovetypography.com, webdesignerdepot.com, pearsonified.com, css-tricks.com, yoast.com and others — W3 Total Cache improves the user experience of your blog by improving your server performance, caching every aspect of your site, reducing the download time of your theme and providing transparent content delivery network (CDN) integration.

Benchmark – vítězí W3 Total cache »

Combining some of the plugins can lead to an increase in performance such as Hyper Cache + DB Cache Reloaded, which is the best out of the box cache plugin configuration. Despite the allure of W3 Total Cache’s professionalism and only slightly less admired performance, I prefer to retain some manual control over my blog. For those on a medium priced shared server or if you like the idea of installing and forgetting, the W3 Total Cache plugin will be your ideal choice.

A lot of people still use WP-Cache and WP Super Cache. They are still respectable WordPress caching plugins but consider trading up for Hyper Cache or W3 Total Cache. These newer caching plugins prove better performance and install/config much easier and cleaner. Also the development communities around these newer plugins are much more active and attentive to their users.

Quick Cache
http://www.primothemes.com/post/quick-cache-plugin-for-wordpress/
http://wordpress.org/extend/plugins/quick-cache/

Quick Cache takes a real-time snapshot ( building a cache ) of every Page, Post, Category, Link, etc. These snapshots are then stored ( cached ) intuitively, so they can be referenced later, in order to save all of that processing time that has been dragging your site down and costing you money.

The Quick Cache plugin uses configuration options, that you select from the options panel. See: Config Options under Quick Cache. Once a file has been cached, Quick Cache uses advanced techniques that allow it to recognize when it should and should not serve a cached version of the file. The decision engine that drives these techniques is under your complete control through options on the back-end. By default, Quick Cache does not serve cached pages to users who are logged in, or to users who have left comments recently. Quick Cache also excludes administrational pages, login pages, POST/PUT/GET requests, CLI processes, and any additional User-Agents or special pattern matches that you want to add.

Super Cache
http://wordpress.org/extend/plugins/wp-super-cache/
http://ocaoimh.ie/wp-super-cache/

WP Super Cache is a static caching plugin for WordPress. It generates html files that are served directly by Apache without processing comparatively heavy PHP scripts. By using this plugin you will speed up your WordPress blog significantly.

Hyper Cache
http://wordpress.org/extend/plugins/hyper-cache/

Hyper Cache is an experimental really aggressive cache for WordPress.

AskApache Crazy Cache

http://www.askapache.com/wordpress/crazy-cache-wordpress-plugin.html

This sweet little plugin does one thing very well. It caches all the posts on your entire blog at the same time, if you are using WP-Cache, WP-Super-Cache, or Hyper-Cache.

Quick Page/Post Redirect Plugin
http://wordpress.org/extend/plugins/quick-pagepost-redirect-plugin/
http://www.fischercreativemedia.com/wordpress-plugins/quick-pagepost-redirect-plugin/

Redirect Pages or Posts to another location quickly.

It adds an option box to the page or post edit section where you can specify the redirect location and type of redirect that you want, temporary, permanent, or meta. The redirect Location can be to another WordPress page/post or any other website or external URL. It allows the use of a full URL path, post or page ID, permalink or page-name. Additional 301 Redirects can also be added for non-existent posts or pages – helpful for sites converted to WordPress where you don’t have the ability to edit the .htaccess file.

S výhodou lze využít když potřebujeme do navigace mezi ostatní stránky dostat obsah nějaké rubriky. Zřídíme stránku a přesměrujeme ji na obsah rubriky.

Simple Redirect
https://wordpress.org/plugins/simple-redirect/

Easily redirect any post or page to another page with a dropdown menu or by manually typing in a URL.

Page Links To
http://wordpress.org/extend/plugins/page-links-to/
http://txfx.net/wordpress-plugins/page-links-to/

This plugin allows you to make a WordPress page or post link to a URL of your choosing, instead of its WordPress page or post URL. It also will redirect people who go to the old (or “normal”) URL to the new one you’ve chosen (301 Moved Permanently redirects are standard, but you can choose a 302 Moved Temporarily redirect if you wish).

This functionality is useful for setting up navigational links to non-WordPress sections of your site or to off-site resources.

You can also use it to create a hand-crafted menu that links to pages, posts, categories, or anything within your site.

Redirect by Custom Field
http://wordpress.org/plugins/redirect-by-custom-field/

This plugin lets you easily create such „redirecting“ posts or pages by simply setting a custom field.

Usage: Add the custom field with label „redirect“ to any post or page. Enter the redirect target URL as the value of that custom field. Now all links on your site to that post or page will be replaced with that redirect URL! If you try to visit the permalink URL for that page, it will redirect the user to that redirect URL too.

The strings %home% and %site% in URLs are replaced by the WordPress home URL and site URLs.

Zobrazení obsahu pouze přihlášeným uživatelům

Do souboru functions.php (Vzhled > Upravit soubory) stačí přidat následující:


add_shortcode( 'member', 'member_check_shortcode' );

function member_check_shortcode( $atts, $content = null ) {
	 if ( is_user_logged_in() && !is_null( $content ) && !is_feed() )
		return $content;
	return '';
}

Pak už stačí kdekoli v příspěvku „obalit“ text určený pouze registrovaným uživatelům tagem [member]:


[member]
Toto se zobrazí pouze přihlášeným uživatelům
[/member]

Je-li potřeba to nastavit už v šabloně vzhledu, je třeba použít


<?php
if (is_user_logged_in()):
echo "Toto se zobrazí pouze přihlášeným uživatelům";
endif;
?>

SQL dotazy k nezaplacení

Náhrada jednoho řetězce za druhý v libovolné tabulce a poli


UPDATE table_name
SET field_name = replace( field_name, 'tohle_najdi', 'timhle_nahrad' );

k nezaplacení např. při přesunu webu na jinou adresu, lze tak nahradit absolutní URL obrázků, siteurl-homeurl nebo guide


UPDATE wp_posts SET post_content = REPLACE(post_content, 'http://stara.cz', 'http://nova.cz');
UPDATE wp_posts SET guid = REPLACE(guid, 'http://stara.cz', 'http://nova.cz');
UPDATE wp_options SET option_value = REPLACE(option_value, 'http://stara.cz', 'http://nova.cz');
UPDATE wp_postmeta SET meta_value = REPLACE(meta_value, 'http://stara.cz', 'http://nova.cz');

Tento způsob ale bohužel neřeší případ tzv. serializovaných dat Při migraci WP na jiné url je proto jistější použít nějaký specializovaný nástroj pro náhradu v serializovaných datech, např.:

http://pixelentity.com/wordpress-search-replace-domain/

https://interconnectit.com/products/search-and-replace-for-wordpress-databases/

nebo pluginy WP Migrate DB či Better Search Replace

WP Migrate DB migrates your database by running find & replace on URLs and file paths, handling serialized data, and saving an SQL file.

Někdy je potřeba jen přidat text na konec obsahového pole


UPDATE wp_posts SET post_content =
concat(post_content, ' ...') WHERE post_type = 'post';

nebo hromadně nahradit url uvedené komentátorem


UPDATE wp_comments
SET comment_author_url =
REPLACE( comment_author_url, 'http://www.stara.cz', 'http://www.nova.cz');

Změna hesla


UPDATE 'wp_users'
SET 'user_pass' = MD5('PASSWORD') WHERE 'user_login' ='admin' LIMIT 1;

Přesun příspěvků z jednoho autora na jiného

LEFT JOIN wp_postmeta c ON (a.ID = c.post_id);

Dávkové vymazání komentářů označených jako spam

Výpis e-mailů vašich komentátorů


SELECT DISTINCT comment_author_email
FROM wp_comments;

Vymazání všech tagů u příspěvků najednou

FROM
database.prefix_terms AS a
LEFT JOIN database.prefix_term_taxonomy AS c ON a.term_id = c.term_id
LEFT JOIN database.prefix_term_relationships AS b
ON b.term_taxonomy_id = c.term_taxonomy_id
WHERE (c.taxonomy = 'post_tag' AND c.count = 0);

Výpis všech nepotřebných *post meta* záznamů


SELECT * FROM wp_postmeta pm
LEFT JOIN wp_posts wp ON wp.ID = pm.post_id
WHERE wp.ID IS NULL;

Hromadné vypnutí komentářů u starších příspěvků


UPDATE wp_posts SET comment_status = 'closed'
WHERE post_date &lt; '2009-01-01' AND post_status = 'publish';

My Page Order

http://geekyweekly.com/mypageorder

Allows you to set the order of pages through a drag and drop interface. The default method of setting the order page by page is extremely clumsy, especially with a large number of pages. The plugin also installs a replacement widget that exposes all the options of the wp_list_pages template function.
