[英]Looping through multidimentional array in twig
I have created this mulidimentional array in a php model. 我已经在php模型中创建了这个数组。 which is below. 在下面。
$handle = opendir($this->path);
while(false !== ($file = readdir($handle)))
{
if($file != "." && $file != "..")
{
$this->content[] = array(
'name' => $file,
'name_href' => $file,
'extn' => $this->findExts($file),
'file_size' => number_format(filesize($this->path . '/' . $file)),
'mod_time' => date("M j Y g:i A", filemtime($this->path . '/' . $file)),
'time_keys' => date("YmdHis", filemtime($this->path . '/' . $file))
);
}
}
closedir($handle);
and I am trying to loop through it with twig. 而且我正试图用树枝环遍它。 But the page does not show any content. 但是页面没有显示任何内容。 However if I print_r
the $content
array all the data shows up so I know the array is not empty. 但是,如果我使用print_r
$content
数组显示所有数据,那么我知道该数组不为空。 Can someone help me find out how I can loop through this and display the content. 有人可以帮助我找出如何循环浏览并显示内容。
here is what I have tried 这是我尝试过的
{% for key, value in content %}
<li>
<a class="show_content" href="{{ value.name_href }}">{{ value.name }}</a>
</li>
{% endfor %}
but this does not display anything. 但这不会显示任何内容。 And here is where I pass the content into the twig template. 这是我将内容传递到树枝模板的地方。
$template = $twig->loadTemplate('layout.html.twig');
$template->display(array('content' => $content));
So the issue was not the loop. 因此,问题不是循环。 It was working fine. 运行正常。
The issue was I was not passing the content in the right way, I just was not paying attention. 问题是我没有正确地传递内容,我只是没有注意。 Silly mistake. 愚蠢的错误。
I had this: $template->display($content);
我有这个: $template->display($content);
and it needed to be this $template->display(array('content' => $content));
它必须是这个$template->display(array('content' => $content));
