Opis

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 “WordPress“.

Additional features of the plugin controlled via settings and filters:

Text linkification can be enabled for comments (it isn’t by default)
Text linkification can be made case sensitive (it isn’t by default)
Text linkification can be limited to doing only one linkification per term, per post (by default, all occurrences of a term are linkified)
Text linkification links can be set to open in a new window (it isn’t by default)

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.

Hooks

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:

$hooks (array): Array of hooks that will be text linkified.

Example:

/**
 * 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' );

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:

$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.

Example:

// Prevent text linkification from ever being enabled in comments.
add_filter( 'c2c_linkify_text_comments', '__return_false' );

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:

$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.

Example:

/**
 * Programmatically adds more text to be linked.
 *
 * @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' );

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.

Arguments:

$state (bool): Either true or false indicating if text matching is case sensitive. The default value will be the value set via the plugin’s settings page.

Example:

// Prevent text matching from ever being case sensitive.
add_filter( 'c2c_linkify_text_case_sensitive', '__return_false' );

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:

$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.

Example:

// Only linkify a term once per post.
add_filter( 'c2c_linkify_text_replace_once', '__return_true' );

c2c_linkify_text_open_new_window (filter)

The ‘c2c_linkify_text_open_new_window’ hook allows you to customize or override the setting indicating if links should open in a new window.

Arguments:

$state (bool): Either true or false indicating if links should open in a new window. The default value will be the value set via the plugin’s settings page, which itself is defaulted to false.

Example:

// Make links open in a new window.
add_filter( 'c2c_linkify_text_open_new_window', '__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.

Arguments:

$new_text (string): The link markup that will replace $old_text.
$old_text (string): The text being replaced/linkified.
$link (string): The URL that $old_text is to be linked to.
$text_to_link (array): The full array of text and the URLs they should link to.

Example:

/**
 * Disable linkification of links for posts that have the 'disable_linkify_text'
 * custom field defined.
 *
 * @param array  $display_link  The associative array of attributes to be used for the link.
 * @param string $old_text      The text being replaced/linkified.
 * @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 ) {
    if ( get_metadata( 'post', get_the_ID(), 'disable_linkify_text', true ) ) {
        $display_link = $old_text;
    }
    return $display_link;
}
add_filter( 'c2c_linkify_text_linked_text', 'selectively_disable_text_linkification', 10, 4 );

c2c_linkify_text_link_attrs (filter)

The ‘c2c_linkify_text_link_attrs’ hook allows you to add or customize attributes for the link.

Arguments:

$attrs (array): The associative array of attributes to be used for the link. By default includes ‘href’.
$old_text (string): The text being replaced/linkified.
$link (string): The URL that $old_text is to be linked to.

Example:

/**
 * Force links created by Linkify Text plugin to open in a new tab.
 *
 * @param array $attrs     The associative array of attributes to be used for the link.
 * @param string $old_text The text being replaced/linkified.
 * @param string $link     The URL that $old_text is to be linked to.
 * @return array
 */
function my_linkify_text_attrs( $attrs, $old_text, $link ) {
    $attrs['target'] = '_blank';
    return $attrs;
}
add_filter( 'c2c_linkify_text_link_attrs', 'my_linkify_text_attrs', 10, 3 );

Installation Instructions

Install via the built-in WordPress plugin installer. Or download and unzip linkify-text.zip inside the plugins directory for your site (typically wp-content/plugins/)
Activate the plugin through the ‘Plugins’ admin menu in WordPress
(optional) Go to the Settings -> Linkify Text admin options page and define text and the URLs they should point to

Does this plugin modify the post content in the database?

No. The plugin filters post content on-the-fly.

Will this work for posts I wrote prior to installing this plugin?

Yes, if they include terms that you have defined to be linkified.

What post fields get handled by this plugin?

By default, the plugin filters the post content, post excerpt fields, widget text, and optionally comments and comment excerpts. You can use the ‘c2c_linkify_text_filters’ filter to modify that behavior (see Filters section). There is a setting you can change to make text linkifications apply to comments as well.

Is the plugin case sensitive?

By default, yes. There is a setting you can change to make it case insensitive. Or if you are a coder, you can use the ‘c2c_linkify_text_case_sensitive’ filter (see Filters section).

What if the word or phrase is already linked in a post?

Already linked text will not get linked again by this plugin (regardless of what the link may be).

Will all instances of a given term be linked in a single post?

By default, yes. There is a setting you can change so that only the first occurrence of the term in the post gets linked. Or if you are a coder, you can use the ‘c2c_linkify_text_replace_once’ filter (see Filters section).

Is there an efficient way to link multiple terms to the same link without repeating the link in the settings field (which can be tedious and prone to errors)?

Yes. You can reference another term by specifying its link as another term in the list prepended with a colon (‘:’). For instance:

WP => https://wordpress.org,
WordPress => :WP
dotorg => :WP

Given the above terms to link, all terms would link to ‘https://wordpress.org’. The latter two all reference the link used for the term “WP”.

NOTE: The referenced term must have an actual link defined and not be a reference to another term. (Basically, nested references are not currently supported.)

How can I get text linkification to apply for custom fields (or something not linkified by default)?

You can add to the list of filters that get text linkified using something like this (added to your theme’s functions.php file, for instance):

/**
 * Enable text linkification for custom fields.
 *
 * @param array $filters Array of filters that the plugin should hook.
 * @return array
 */
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' );

Can I only have text linkification take place for only a part of a post (such as text inside certain tags, or except for text in certain tags)?

No. The plugin applies fully to the post content. With some non-trivial coding the plugin could be utilized to affect only targeted parts of a post’s content, but it’s not something that will be built into the plugin.

Can I change how the link gets created because I want to add a ‘title’ attribute to the link?

Yes, with a bit of code. You can define the title attribute text in your replacement string, like so:

WP => https://wordpress.org || This is the link title

Now the code:

/**
 * Force links created by Linkify Text plugin to open in a new tab.
 *
 * @param array  $attrs         The associative array of attributes to be used for the link.
 * @param string $old_text      The text being replaced/linkified.
 * @param string $link_for_text The URL that $old_text is to be linked to.
 * @return array
 */
function add_title_attribute_to_linkified_text( $attrs, $old_text, $link_for_text ) {
    // The string that you chose to separate the link URL and the title attribute text.
    $separator = ' || ';

    // Only change the linked text if a title has been defined
    if ( false !== strpos( $link_for_text, $separator ) ) {
        // Get the link and title that was defined for the text to be linked.
        list( $url, $title ) = explode( $separator, $link_for_text, 2 );

        // Set the attributes ('href' must be overridden to be a proper URL).
        $attrs['href']  = $url;
        $attrs['title'] = $title;
    }

    return $attrs;
}
add_filter( 'c2c_linkify_text_link_attrs', 'add_title_attribute_to_linkified_text', 10, 3 );

Can I selectively disable text linkification?

Yes, with some custom code making use of the ‘c2c_linkify_text_linked_text’ filter. The code should determine if the given text linkification should be disabled, and if so, return the second argument sent via the filter. See the docs for the ‘c2c_linkify_text_linked_text’ filter for an example of how a custom field could be used to disable all text linkifications on a per-post basis. No doubt your particular situation will require custom logic to determine when to disable linkification.

Does this plugin include unit tests?

Yes.

Was a little dubious installing this, as I'm running WP v.5.5. I've done only limited testing so far, but no problems yet. It does exactly what it's supposed to do, and does it easily and well. Perhaps it hasn't been updated for such a long time simply because it doesn't need to be. I'd give it 5 stars, except that I haven't yet found a way to add a unique style to the created hyperlinks ... probably my problem, not the plugin's!

vincentfijian 14. prosinca 2019.

Used it on our website to quickly add several hundred links to internal pages and this just worked perfectly! Thank you so much!

UfukArt 25. studenoga 2018.

Thanks to devs. great working.

Love this plugin! Saves so much time, does exactly what it says, super simple. Many Thanks!

Coptic-Treasures 20. rujna 2016.

Finally after searching for months, I found this plugin. It can handle linking Arabic terms (more than one word) and link them successfully to the links I want. All other plugin I tried did not do the job. Also, it can link internal and external links. Thanks a lot for the author.

This is good working plugin. Thanks to the creator.
