问题描述
我正在使用以下代码来显示我从gravatar.com获取的图像，因此我想使用bootstrap CSS类使其更具吸引力.添加样式而不是显示图像后，它立即向我显示该图像的链接，当我重定向到该链接时，便可以看到该图像.为什么我得到这个?
I am using following piece of code to display an image which I am fetching from gravatar.com, so I want to use a bootstrap CSS class to make it more attractive. As soon as I add the style rather than showing the image it shows me the link to the image, when I redirect to the link I am able to see the image. Why I am getting this?
$html[] = JHtml::_('image', $grav_url,'class="img-circle"', JText::_('PLG_CONTENT_AVATAR'), null, true)
这里$grav_url是我要获取图像的url，而img-circle是我要使用的引导程序类.
Here $grav_url is the url I am getting for the image and img-circle is the bootstrap class that I want to use.
推荐答案
我相信您正在使用的库在这里:
I believe the library you're using is here:
https://github.com. com/joomla/joomla-cms/blob/staging/libraries/cms/html/html.php#L567
因此您可以在参数列表中看到$attribs的一个参数，其类型为数组.另一件事是您还必须传递一个附加的$ alt参数，这可能是您的jtext混乱了.要将其传递给方法，您将执行以下操作:
So you can see in the parameter list that there is a param for $attribs which is of the type array. The other thing is there is an additional $alt param you have to pass which might be your jtext just out of order. To pass that to the method you would do:
$html[] = JHtml::_('image', $grav_url, JText::_('PLG_CONTENT_AVATAR'), array('class'=>'img-circle'), true)
或者您可以在方法外将数组构建为变量:
Or you could build the array outside the method as a variable:
$attribs = array();
$attribs['class'] = 'img-circle'; // I think this should work? haven't tested though.
$html[] = JHtml::_('image', $grav_url, JText::_('PLG_CONTENT_AVATAR'), $attribs, true)
