hook_theme() 不传递参数
我目前编写了一个生成块的模块。输出应该由模板定义。没什么特别的，但争论似乎没有得到正确的通过。
这是主题方法：
/* # Theme {{{*/
function browse_by_taxonomy_theme() {
return array(
'browse_by_taxonomy_block' => array(
'template' => 'browse_by_taxonomy_block',
'arguments' => array(
'next' => null,
'previous' => null,
'term' => null,
'hide_if_null' => variable_get('browse_by_taxonomy_hide_links', false)
)
)
);
}/*}}}*/
它的调用方式如下：
$block['content'] = theme('browse_by_taxonomy_block', "next", "previous", $tid);
即使我将其设置为最小值，它也不起作用：
function browse_by_taxonomy_block($op = 'list', $delta = 0, $edit = array()) {
switch ($op) {
case 'list':
$block = array(array('info' => t("Browse by taxonomy")));
return $block;
case 'view':
# […] Dragons be here
return array(
'subject' => null,
'content' => theme('browse_by_taxonomy_block', "next", "previous", "p")
);
}
}/*}}}*/
但在我的模板中，一切都是null
var_dump($previous); # => NULL
var_dump($next); # => NULL
var_dump($hide_if_null); # => NULL
var_dump($term); # => NULL
在我编写的另一个模块中，我以几乎相同的方式完成了它并且它有效。这次我做错了什么？
I currently write a module that generates a block. The output should be defined by a template. Nothing special, yet the arguments don't seem to get passed properly.
This is the theme-method:
/* # Theme {{{*/
function browse_by_taxonomy_theme() {
return array(
'browse_by_taxonomy_block' => array(
'template' => 'browse_by_taxonomy_block',
'arguments' => array(
'next' => null,
'previous' => null,
'term' => null,
'hide_if_null' => variable_get('browse_by_taxonomy_hide_links', false)
)
)
);
}/*}}}*/
And it's being called like that:
$block['content'] = theme('browse_by_taxonomy_block', "next", "previous", $tid);
Even when i put it to the minimum of this it does not work:
function browse_by_taxonomy_block($op = 'list', $delta = 0, $edit = array()) {
switch ($op) {
case 'list':
$block = array(array('info' => t("Browse by taxonomy")));
return $block;
case 'view':
# […] Dragons be here
return array(
'subject' => null,
'content' => theme('browse_by_taxonomy_block', "next", "previous", "p")
);
}
}/*}}}*/
But in my template everything is null
var_dump($previous); # => NULL
var_dump($next); # => NULL
var_dump($hide_if_null); # => NULL
var_dump($term); # => NULL
In another module i wrote i did it pretty much the same way and it works. What am I doning wrong this time?

该问题很可能是由缓存问题引起的，因为 Drupal 出于性能原因缓存了所有主题信息。
Most likely the problem is caused by caching issues, as Drupal caches all theme info for performance reasons.
在这种情况下，缓存是魔鬼，我的朋友......只需刷新您的主题，它很可能会起作用。至少在我的情况下是这样的，经过长时间的搜索，充满了咒骂和咒骂，我终于尝试了，宾果......
Caching is the devil in this case my frend... just refresh your theme and it will most likely work. That was the thing in my case atleast, after a long long long search filled with lots of cursing and swearing I finally tried that and BINGO...
