They are primarily site structure and are never to be mixed with the post content editor. With Full Site Editing and block based themes, users can create their own arbitrary Template Parts, save those in the database for their site, and re-use them throughout their site. Template parts are equivalent \u2013 in blocks \u2013 of theme template parts. They are generally defined by a theme first, carry some semantic meaning (could be swapped between themes such as a header), and can only be inserted in the site editor context (within \u201ctemplates\u201d).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"block-templates\">Block Templates<\/h2>\n\n\n\n<p>A template is a predefined arrangement of blocks, possibly with predefined attributes or placeholder content. You can provide a template for a post type, to give users a starting point when creating a new piece of content, or inside a custom block with the&nbsp;<code><strong>InnerBlocks<\/strong><\/code>&nbsp;component. At their core, templates are simply HTML files of block markup that map to templates from the standard WordPress template hierarchy, for example index, single or archive. This helps control the front-end defaults of a site that are not edited via the Page Editor or the Post Editor. See the&nbsp;<a href=\"https:\/\/developer.wordpress.org\/block-editor\/developers\/block-api\/block-templates\/\">templates documentation<\/a>&nbsp;for more information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"block-themes\">Block Themes<\/h2>\n\n\n\n<p>A theme built in block forward way that allows Full Site Editing to work. The core of a block theme are its block templates and block template parts. To date, block theme templates have been HTML files of block markup that map to templates from the standard WordPress template hierarchy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"block-type\">Block type<\/h2>\n\n\n\n<p>In contrast with the blocks composing a particular post, a block type describes the blueprint by which any block of that type should behave. So while there may be many images within a post, each behaves consistent with a unified image block type definition.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"blog\">Blog<\/h2>\n\n\n\n<p>A <strong>blog<\/strong>, or <strong>weblog<\/strong>, is an online journal, diary, or serial published by a person or group of people.\n<\/p>\n\n\n\n<p>Blogs are commonly used by individuals, peer groups, companies, or organizations.<\/p>\n\n\n\n<p>Blogs often contain public as well as private content. Depending on the functionality of the <a href=\"#content-management-system\">CMS<\/a>  software that is used, some authors may restrict access \u2014 through the  use of accounts or passwords \u2014 to content that is too personal to be  published publicly. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"blogging\">Blogging<\/h2>\n\n\n\n<p><strong>Blogging<\/strong> is the act of writing in one&#8217;s blog.

When a request is\nsubmitted, the web site verifies if a previously generated nonce\nexpected for this particular kind of request was sent along and decides\nwhether the request can be safely processed, or a notice of failure\nshould be returned. This could prevent unwanted repeated, expired or\nmalicious requests from being processed.\n<\/p>\n\n\n\n<p>Nonce is usually included in a hidden HTML form field or as a\npart of an URL and therefore sent with a request by submitting a form\nfield or visiting a link. If a request is not verified, the web site\ncould generate a new nonce in its response and prompt the user to\nintentionally  confirm the repetition of the request.

Once you have uploaded the plugin file, you should\nbe able to &#8220;turn it on&#8221; or Enable it from the &#8220;Plugins&#8221; page in the\nadministration interface of your weblog. The WordPress source code\ncontains hooks that can be used by plugins.\n<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li> See also: <a href=\"https:\/\/codex.wordpress.org\/Glossary#Hack\">Hack<\/a>, <a href=\"https:\/\/codex.wordpress.org\/Glossary#Hacking\">Hacking<\/a><\/li>\n\n\n\n<li> Related articles: <a href=\"https:\/\/codex.wordpress.org\/Plugins\">Plugins<\/a><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"port\">Port<\/h2>\n\n\n\n<p>Within the context of the WordPress community, a <strong>port<\/strong> is a bit\n of code that has been rewritten to be compatible with WordPress.

The query string in a <a href=\"http:\/\/en.wikipedia.org\/wiki\/Uniform_Resource_Identifier\">URI<\/a>\n comes after an initial question mark, and may contain several\nparameters separated by ampersands.  WordPress uses query strings to\nindicate criteria to search for specific posts or sets of posts in the\ndatabase. The use of query strings is generally believed to impede the\nindexing of dynamic pages by search engines. For this reason, it is\noften desirable to use a method such as <a href=\"https:\/\/codex.wordpress.org\/Glossary#mod_rewrite\">mod_rewrite<\/a> to reduce exposure of query strings to search engines and other site visitors.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"query-variable\">Query Variable<\/h2>\n\n\n\n<p>A variable passed through the <a href=\"https:\/\/codex.wordpress.org\/Glossary#Query_string\">query string<\/a>.

Spam, in general terms, is an email or\nother forms of unsolicited advertising. Spam is very easy to spread\nthroughout the internet, and works on the principle that if you send out\n thousands, or hundreds of thousands of unsolicited advertisements,\nscams, or other questionable methods of making money, that you only need\n a very small percentage of people to be fooled and you will make lots\nof money.\n<\/p>\n\n\n\n<p>Common spam these days comes from online gambling sites and those\n trying to sell drugs for &#8220;male enhancement.&#8221; Lately, web logs, or\nblogs, as we call them, have been targeted by spammers to try to\nincrease their site ratings in the search engines. Spammers use various\nmethods to distribute their electronic junk mail, and employ bots, or\ncomputer programs to quickly and easily send email or comments to\nmillions of addresses and <a href=\"https:\/\/codex.wordpress.org\/Glossary#IP_address\">IPs<\/a> all over the world.\n<\/p>\n\n\n\n<p>Spammers can be difficult to track down as they often hijack peoples&#8217; email and <a href=\"https:\/\/codex.wordpress.org\/Glossary#IP_address\">IP<\/a> addresses. When this happens, it may appear a friend sent you the spam, but in fact, the spammer&#8217;s <a href=\"http:\/\/en.wikipedia.org\/wiki\/Internet_bot\">bot<\/a> grabbed your friend&#8217;s email address and used it to hide the true source of the spam.

Think of it like a <a href=\"https:\/\/codex.wordpress.org\/Glossary#Category\">Category<\/a>,\n but smaller in scope. A Post may have several tags, many of which\nrelate to it only peripherally. Like Categories, Tags are usually linked\n to a page which shows all Posts having the same Tag.

These indexes are known as character sets. This is invaluable\nfor users hosting <a href=\"https:\/\/codex.wordpress.org\/Localization\">WordPress in a non-English language<\/a>.\n<\/p>\n\n\n\n<p>The most widely used collections of these character sets are the <a href=\"https:\/\/en.wikipedia.org\/wiki\/ISO\/IEC_8859\">iso-8859<\/a> with <a href=\"http:\/\/en.wikipedia.org\/wiki\/ISO_8859-1\">iso-8859-1<\/a> and <a href=\"http:\/\/en.wikipedia.org\/wiki\/ISO_8859-15\">iso-8859-15<\/a>  (which contains the euro sign) being the most common; they are also known as  Latin1 and Latin9. These character sets use 8 bits (a single byte) for  each character, allowing for 255 different characters (256, counting  null). However, when considering that Latin-based languages aren&#8217;t the  only ones in the world (think Japanese or Hebrew), 255 characters aren&#8217;t  nearly enough. <\/p>\n\n\n\n<p>There is a wide index of characters known as <a href=\"http:\/\/en.wikipedia.org\/wiki\/Unicode\">Unicode<\/a>.\n Unicode has so many characters that sometimes more than 16 bits (2\nbytes!) are required to represent them. Furthermore, the first 127\ncharacters of Unicode are the same as the first 127 of the most widely\nused character set &#8211; iso-8859-1. For this purpose, UTF, the Unicode\nTranslation Format, was created. UTF uses different numbers of bits for\ncharacters, and allows for the entire range of Unicode to be used. What\nyou should probably know is:\n<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li> UTF-8 is an 8-bit-minimum type of UTF.
