CakePHP相当于html代码 [英] CakePHP equivalent of html code

问题描述

我正在使用一个cakePHP项目，我需要使用PHP创建一个按钮，删除数据库中的一个条目，但我想在上述按钮上显示twitter bootstrap trashcan图标。

I am working on a cakePHP project and I need to create a button using PHP that will delete an entry in a database, but I want to display the twitter bootstrap trashcan icon on said button.

包含twitter启动图标的代码是

The code to include the icon from twitter bootstrap is;

<i class="icon-trash"></i>

我需要它的PHP代码是：

And the PHP code I need it to work in is;

<?php echo $this->Form->postLink(__('Delete'), 
    array(
        'action' => 'delete', 
        $skill['Skill']['SkillID']),
        array(
              'class'=>'btn'),
              null, 
              __('Are you sure you want to delete # %s?', 
              $skill['Skill']['SkillID']
));?>

有没有人知道如何实现html在这个PHP代码，所以我可以替换文本'具有图标？

Does anyone know how to implement the html in this PHP code so I can replace the text 'Delete' with the icon?

推荐答案

echo $this->Form->postLink(
    '<i class="icon-trash"></i> '.__('Delete'), 
    array(
        'action' => 'delete', 
        $skill['Skill']['SkillID']
    ),
    array(
        'class'=>'btn',
        'escape' => false
    ),
    null, 
    __('Are you sure you want to delete # %s?', 
        $skill['Skill']['SkillID'] )
);

'escape'=> false 使CakePHP显示HTML未转义。

'escape' => false makes CakePHP display the HTML unescaped.

它可能（根据CSS）也工作，如果你只是添加 icon-trash class to the link。

It might (depending on the CSS) also work if you just add the icon-trash class to the link.

echo $this->Form->postLink(__('Delete'), 
    array(
        'action' => 'delete', 
        $skill['Skill']['SkillID']),
        array(
              'class'=>'btn icon-trash'),
              null, 
              __('Are you sure you want to delete # %s?', 
              $skill['Skill']['SkillID']
));
