This plugin allows you to define words or phrases that, whenever they appear in your posts or pages, get automatically linked to the URLs of your choosing. For instance, wherever you may mention the word “WordPress”, that can get automatically linked as “<a href="https://wordpress.org" rel="ugc">WordPress</a>“.
Additional features of the plugin controlled via settings and filters:
<ul>
<li>Text linkification can be enabled for comments (it isn’t by default)</li>
<li>Text linkification can be made case sensitive (it isn’t by default)</li>
<li>Text linkification can be limited to doing only one linkification per term, per post (by default, all occurrences of a term are linkified)</li>
<li>Text linkification links can be set to open in a new window (it isn’t by default)</li>
</ul>
You can also link multiple terms to the same link and only define that link once in the settings via use of a special link syntax.
A number of filters exist to programmatically customize the behavior of the plugin, all of which are documented.

<h3>Hooks</h3>
The plugin exposes a number of filters for hooking. Typically, code making use of filters should ideally be put into a mu-plugin or site-specific plugin (which is beyond the scope of this readme to explain). Bear in mind that most of the features controlled by these filters are configurable via the plugin’s settings page. These filters are likely only of interest to advanced users able to code.
c2c_linkify_text_filters (filter)
The ‘c2c_linkify_text_filters’ hook allows you to customize what hooks get text linkification applied to them.
Arguments:
<ul>
<li>$hooks (array): Array of hooks that will be text linkified.</li>
</ul>
Example:
<pre><code>/**
 * Enables text linkification for custom fields.
 *
 * @param array $filters The filters handled by the Linkify Text plugin.
 */
function more_text_replacements( $filters ) {
 $filters[] = 'the_meta'; // Here you could put in the name of any filter you want
 return $filters;
}
add_filter( 'c2c_linkify_text_filters', 'more_text_replacements' );
</code></pre>
c2c_linkify_text_comments (filter)
The ‘c2c_linkify_text_comments’ hook allows you to customize or override the setting indicating if text linkification should be enabled in comments.
Arguments:
<ul>
<li>$state (bool): Either true or false indicating if text linkification is enabled for comments. The default value will be the value set via the plugin’s settings page.</li>
</ul>
Example:
<pre><code>// Prevent text linkification from ever being enabled in comments.
add_filter( 'c2c_linkify_text_comments', '__return_false' );
</code></pre>
c2c_linkify_text (filter)
The ‘c2c_linkify_text’ hook allows you to customize or override the setting defining all of the text phrases and their associated links.
Arguments:
<ul>
<li>$linkify_text_array (array): Array of text and their associated links. The default value will be the value set via the plugin’s settings page.</li>
</ul>

 *
 * @param array $text_to_links Array of text and their associated URLs.
 */
function my_text_linkifications( $text_to_links ) {
 // Add text link
 $text_to_links['Matt Mullenweg'] => 'https://ma.tt';

 // Unset a text link that we never want defined
 if ( isset( $text_to_links['WordPress'] ) ) {
 unset( $text_to_links['WordPress'] );
 }

 // Important! Return the changes.
 return $text_to_links;
}
add_filter( 'c2c_linkify_text', 'my_text_linkifications' );
</code></pre>
c2c_linkify_text_case_sensitive (filter)
The ‘c2c_linkify_text_case_sensitive’ hook allows you to customize or override the setting indicating if text matching for potential text linkification should be case sensitive or not.

</ul>
Example:

</code></pre>
c2c_linkify_text_replace_once (filter)
The ‘c2c_linkify_text_replace_once’ hook allows you to customize or override the setting indicating if text linkification should be limited to once per term per piece of text being processed regardless of how many times the term appears.
Arguments:
<ul>
<li>$state (bool): Either true or false indicating if text linkification is to only occur once per term. The default value will be the value set via the plugin’s settings page.</li>
</ul>
Example:
<pre><code>// Only linkify a term once per post.
add_filter( 'c2c_linkify_text_replace_once', '__return_true' );

c2c_linkify_text_linked_text (filter)
The ‘c2c_linkify_text_linked_text’ hook allows you to customize or override the replacement link markup for a given string. Return the value of $old_text to effectively prevent the given text linkification.

 * @param string $link_for_text The URL that $old_text is to be linked to.
 * @param string $text_to_link The full array of text and the URLs they should link to.
 * @return string
 */
function selectively_disable_text_linkification( $display_link, $old_text, $link_for_text, $text_to_link ) {

Linkify Text

Very Useful, Working Perfect

Automatically add links to words or phrases in your posts.

Ultralinks bring all the intereseting, useful or relevant information about anything you see on the internet, straight to you, with just one click.
Hyperlinks have their place, but ultralinks can do so much more. Ultralinks can perform many of the same functions hyperlinks do, but better. Ultralinks can even do many things that hyperlinks can’t do at all. They can take your website to the next level.
Check out our introduction video at <a href="https://ultralink.me" title="ultralink.me" rel="nofollow ugc">ultralink.me</a>
Cleaner, Denser Content
Ultralinks are all about making the internet cleaner and less distracting. Ultralinks were designed to be unobtrusive and only have a visual callout when the user is interested in exploring them.
Not only does this make for cleaner, less interrupted content, but it also means that a page can easily contain a much higher density of ultralinks than hyperlinks. All while keeping things neat and tidy.
Web authors can always style ultralinks individually when they want to bring attention to specific content.
Just Write
Web authors don’t need to fret about what to link and what not to link anymore. Every significant thing mentioned in an article can, and often should, have a link on it.
Now you don’t have to debate about linking just the first instance of something or worry about optimal linking density. Just write. Ultralinks from ultralink.me or other databases are added automatically.
Learn about how the central <a href="https://ultralink.me/w/umdatabase.html" title="ultralink.me database" rel="nofollow ugc">ultralink.me database</a> can do all the linking work for you (for free!).
Monetization That Isn’t Annoying
Ultralinks improve websites and the browsing experience by connecting web surfers with the information they want. Sometimes they might want to quickly and easily purchase a product or service they see. As the web site owner, you deserve your cut!
If you have an affiliate account with PHG, Linkshare, Amazon or eBay, those link types are associated with your account. That means that you keep 100% of the commision from any sales.
Annoying ads or inline affiliate links are no longer the only ways to make money from your content. You can now monetize, without compromise, and keep your site beautiful. You can have your cake and eat it too.
