Advanced Custom Fields: Link Picker Field

描述

This add on for the already established Advanced Custom Fields plugin adds a new field type called ‘Link Picker’ which allows the user to enter a URL, or select from the existing pages. It is a thin wrapper around the link selector included with the WYSIWYG field editor.

This plugin is forked from the plugin of the same name hosted at https://github.com/BIOSTALL/ACF-Link-Picker-Field. This version is hosted at https://github.com/ahebrank/ACF-Link-Picker-Field and issues and PRs should be submitted there.

Note: Advanced Custom Fields must be installed for this add-on to work.

兼容性

This ACF field type is compatible with:

• ACF 5
• ACF 4

ACF 4 support is deprecated, and new plugin features will generally not work with ACF 4.

用法

When outputting the link selection on the front end, you will have three object elements available:

• url – The URL of the page
• title – The title of the link, if entered
• target – Will be either a blank string or ‘_blank’, depending on whether the user has ticked the box for the link to open in a new window/tab.
• postid – Not available as part of wp_link, this is an ajax hack to attempt to look up the post ID of a selected link. This will return 0 if the post ID was not found.

Code example:

$mylink = get_field('mylink');
var_dump($mylink);

Outputs:

array(3) {
  ["url"]=>
  string(31) "http://mysite.com/selected/url/"
  ["title"]=>
  string(10) "Link Title"
  ["target"]=>
  string(6) "_blank"
  ["postid"]=>
  int 2231
}
