如何使用 cakephp 和 twitter bootstrap 在表单 postlink 内创建图标

这给了我我想要的：

<?php echo $this->Html->link(
   $this->Html->tag('i', '', array('class' => 'glyphicon glyphicon-edit')) . " Edit",
   array('action' => 'edit', $comment['Comment']['comment_id']),
   array('class' => 'btn btn-mini', 'escape' => false)
); ?>

但是当我创建 Form postLink 时，我不知道如何获取它前面的删除图标。

<?php echo $this->Form->postLink(
   $this->Html->tag('i', '', array('class' => 'glyphicon glyphicon-remove')) . " Delete",
   array('action' => 'delete', $comment['Comment']['comment_id']), null, __('Are you sure you want to delete # %s?', $comment['Comment']['comment_id']),
   array('class' => 'btn btn-mini', 'escape' => false)
); ?>

它给了我<i class="glyphicon glyphicon-remove"></i> Delete

您忘记添加选项escape to false

echo $this->Form->postLink(
   $this->Html->tag('i', '', array('class' => 'glyphicon glyphicon-remove')). " Delete",
        array('action' => 'delete', $comment['Comment']['comment_id']),
        array('escape'=>false),
    __('Are you sure you want to delete # %s?', $comment['Comment']['comment_id']),
   array('class' => 'btn btn-mini')
);
