CakePHP& Twitter Bootstrap CSS按钮图标 [英] CakePHP & Twitter Bootstrap CSS button icons

问题描述

我有这个代码;

<?php echo $this->Form->postLink(__('Delete'), 
            array('action' => 'delete', $homepage['Homepage']['ContentID']),
            array('class'=>'btn icon-plus'),
            __('Are you sure you want to delete # %s?', $homepage['Homepage']['ContentID'])); ?>

它显示文本'Delete'我想把twitter的图标从twitter bootstrap css包。但是当我这样做;

Where it displays the text 'Delete' I would like to put the trashcan icon from the twitter bootstrap css package. However when I do;

<?php echo $this->Form->postLink(__('<i class="icon-trash"></i>')....

它只显示html而不是抓取图标。

It only displays the html rather than grabbing the icon.

任何人都可以解释为什么它这样做以及如何解决它？

Can anyone explain why its doing this and how I can resolve it?

推荐答案

向第三个参数添加'escape'=> false 选项。

Add 'escape' => false option to the third param.

<?php echo $this->Form->postLink(__('Delete'), 
            array('action' => 'delete', $homepage['Homepage']['ContentID']),
            array('class'=>'btn icon-plus', 'escape' => false),
            __('Are you sure you want to delete # %s?', $homepage['Homepage']['ContentID'])); ?>
