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

Question

这给了我想要的东西:

<?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)
); ?>

但是当我创建一个Form postLink时,我不知道如何在它前面获取删除图标..

<?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

Answer 1

你忘了添加选项escape,以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')
);

使用按钮

                      <?php     echo $this->Form->postLink(
                '<button class="btn btn-danger">
                     <i class="icon-trash icon-white"></i>
                 </button>',
                array(
                      'action'   => 'delete', $post['Post']['id']
                      ),
                array(
                      'class'    => 'tip',
                      'escape'   => false,
                      'confirm'  => 'Are you sure ?'
                     ));
                     ?>
