如何使此过滤器在同一文本中的多个匹配项上运行?
function _embed_link($text, $filter, $format) {
if (preg_match_all("/\[(.*?)\|(node|term)\:(\d+)\]/i", $text, $params)) {
foreach ($params[0] as $key => $param) {
$args = array(
$params[0][$key],
$params[1][$key],
$params[2][$key],
$params[3][$key],
);
$markup = _embed_link_process($args);
$text = preg_replace("/\[(.*?)\|(node|term)\:(\d+)\]/", $markup, $text, 1);
}
}
return $text;
}
这是返回链接的函数
function _embed_link_process($params = array()) {
$output = '';
if ($params[2] == 'node') {
// Find node by it's id
$node = node_load($params[3]);
$output .= render(l($params[1], 'node/'. $node->nid, array(
'attributes' => array(
'class' => array('embed-link', 'embed-link-node', 'embed-link-node-'. $node->nid),
),
)));
}
if ($params[2] == 'term') {
$term = taxonomy_term_load($params[3]);;
$output .= render(l($params[1], 'taxonomy/term/'. $term->tid, array(
'attributes' => array(
'class' => array('embed-link', 'embed-link-term', 'embed-link-term-'. $term->tid),
),
)));
}
return $output;
}
使用过滤器的示例文本:
Ut [点击这里|节点:4] enim ad minim veniam,quis [点击这里|术语:42] nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat . Duis aute irure dolor in repreptderit in velptate velit esse cillum [点击这里|术语:1] dolore eu fugiat nulla pariatur . Excepteur sint occaecat cupidatat non proident,sunt in culpa [点击这里|节点:42] qui officia deserunt mollit anim id est laborum .
目标是通过适当的链接替换每个[...] .

见documentation of preg_replace .
最后一个参数(
1
)明确表示您只想替换第一个匹配项 . 删除它,所有事件都应该更换 .修改函数_embed_link以使用preg_match_all
