yii有两种Breadcrumbs写法,
one:
echo Breadcrumbs::widget([
‘itemTemplate‘ => "<li><i>{link}</i></li>\n", // template for all links
‘links‘ => [
[
‘label‘ => ‘Post Category‘,
‘url‘ => [‘post-category/view‘, ‘id‘ => 10],
‘template‘ => "<li><b>{link}</b></li>\n", // template for this link only
],
[‘label‘ => ‘Sample Post‘, ‘url‘ => [‘post/edit‘, ‘id‘ => 1]],
‘Edit‘,
],
]);
two:
echo Breadcrumbs::widget([
‘links‘ => isset($this->params[‘breadcrumbs‘]) ? $this->params[‘breadcrumbs‘] : [],
]);
第二种在yii的main.php中用实例,就是最简单home->edit;
今天将要说的第一种,
echo Breadcrumbs::widget([
‘itemTemplate‘ => "<li><i>{link}</i></li>\n", // template for all links
‘links‘ => $link,
]);
由于此处需要使用breadcrumbs展现相应的tree结构,经过对link中的数据进行重组可以将程序写成上面的样子,
if (!empty($title)) {
$title = $title;
$title_arr = explode(‘/‘, $title);
foreach ($title_arr as $k => $item) {
if (!empty($item)) {
$link[] = [‘label‘ => $item, ‘url‘ => [‘/tree/edit/‘, ‘id‘ => $item, ‘type‘ => 1,]];
}
}
$title_s = ‘‘;
foreach ($link as $k => $item) {
if ($k !== 0) {
if ($k === 1) {
$title_s = $link[$k - 1][‘label‘];
} else {
$title_s = $title_s . ‘/‘ . $link[$k - 1][‘label‘];
}
$link[$k] = [‘label‘ => $item[‘label‘], ‘url‘ => [‘/tree/edit/‘, ‘id‘ => $item[‘label‘], ‘type‘ => 1, ‘title‘ => $title_s]];
} else {
$title_s = $item[‘label‘];
}
}
$title = $title . ‘/‘ . $node_id[‘nodeId‘];
} else {
$title = $node_id[‘nodeId‘];
}
$link[] = $node_id[‘nodeId‘];
这样就展示了一个tree的结构
