| 自version 1.14.0 版可用 在version 1.36.0 (Gerrit change 593874)版被移除 Used when generating internal and interwiki links in Linker::link(), before processing starts. | |
| 定义函数： | public static function onLinkBegin( $dummy, $target, &$html, &$customAttribs, &$query, &$options, &$ret ) { ... }
|
| 附加钩子： | 在extension.json中：
{
"Hooks": {
"LinkBegin": "MediaWiki\\Extension\\MyExtension\\Hooks::onLinkBegin"

警告
在MediaWiki 1.28中它被HtmlPageLinkRendererBegin取代。
LinkBegin可认为已过时。
详情
Return false to skip default processing and return $ret. See documentation for Linker::link() for details on the expected meanings of parameters.
$dummy: used to be a skin, but that eliminated.$target: the Title that the link is pointing to.&$html&$customAttribs: the HTML attributes (such as title and class; href is ignored) that the<a>tag should have, in associative array form, with keys and values unescaped. Should be merged with default values, with a value of false meaning to suppress the attribute. Other attributes will replace default attributes.&$query: the query string to add to the generated URL (the bit after the "?"), in associative array form, with keys and values unescaped. Query keys and values will be URL-encoded.&$options: 选项。 Can include 'known', 'broken', 'noclasses', 'forcearticlepath', 'http', or 'https'.&$ret: the value to return if your hook returns false.
$options的值
'known': Page is known to exist, so don't check if it does.'broken': Page is known not to exist, so don't check if it does.'noclasses': Don't add any classes automatically (includes "new", "stub", "mw-redirect", "extiw"). Only use the class attribute provided, if any, so you get a simple blue link with no funny icons.'forcearticlepath': Use the article path always, even with a querystring. Has compatibility issues on some setups, so avoid wherever possible.'http': Force a full URL with http:// as the scheme.'https': Force a full URL with https:// as the scheme.
示例
The following code will show all wikilinks as broken (i.e. as red links) by changing the $customAttribs class to "new":
$wgHooks['LinkBegin'][] = 'ExampleExtension::exampleExtensionLinkBegin';
class ExampleExtension {
public static function exampleExtensionLinkBegin( $dummy, $target, &$html, &$customAttribs, &$query,
&$options, &$ret ) {
$customAttribs['class'] = 'new';
return true;
}
}
Another way to achieve the same result would be to change $ret instead of $customAttribs and return false, like this:
$wgHooks['LinkBegin'][] = 'ExampleExtension::exampleExtensionLinkBegin';
class ExampleExtension {
public static function exampleExtensionLinkBegin( $dummy, $target, &$html, &$customAttribs, &$query,
&$options, &$ret ) {
$ret = Html::rawElement ( 'a', array ( 'href' => $target->getFullURL(), 'class' => 'new' ),
$target->getPrefixedDBKey() );
return false;
}
}
Note that neither of these examples will have any effect on interwiki links. For that, you'll need to use LinkEnd. See the example.
