在ecshop首页有$position = assign_ur_here();其中assign_ur_here();是哪个地方传过来的

就是说这个函数是在哪里定义的！

assign_ur_here在lib_main.php的129行,详细内函数容如下:

function assign_ur_here($cat = 0, $str = '')
{

$cur_url = basename(PHP_SELF);
if (intval($GLOBALS['_CFG']['rewrite']))
{
$filename = strpos($cur_url,'-') ? substr($cur_url, 0, strpos($cur_url,'-')) : substr($cur_url, 0, -4);
}
else
{
$filename = substr($cur_url, 0, -4);
}


$page_title = $GLOBALS['_CFG']['shop_title'] . ' - ' . 'Powered by ECShop';
$ur_here = '' . $GLOBALS['_LANG']['home'] . '';


if ($filename != 'index')
{

if (in_array($filename, array('category', 'goods', 'article_cat', 'article', 'brand')))
{

if ('category' == $filename || 'goods' == $filename || 'brand' == $filename)
{
if ($cat > 0)
{
$cat_arr = get_parent_cats($cat);

$key = 'cid';
$type = 'category';
}
else
{
$cat_arr = array();
}
}

elseif ('article_cat' == $filename || 'article' == $filename)
{
if ($cat > 0)
{
$cat_arr = get_article_parent_cats($cat);

$key = 'acid';
$type = 'article_cat';
}
else
{
$cat_arr = array();
}
}


if (!empty($cat_arr))
{
krsort($cat_arr);
foreach ($cat_arr AS $val)
{
$page_title = htmlspecialchars($val['cat_name']) . '_' . $page_title;
$args = array($key => $val['cat_id']);
$ur_here .= ' > ' .
htmlspecialchars($val['cat_name']) . '';
}
}
}

else
{

if ('group_buy' == $filename)
{
$page_title = $GLOBALS['_LANG']['group_buy_goods'] . '_' . $page_title;
$args = array('gbid' => '0');
$ur_here .= ' > ' .
$GLOBALS['_LANG']['group_buy_goods'] . '';
}

elseif ('auction' == $filename)
{
$page_title = $GLOBALS['_LANG']['auction'] . '_' . $page_title;
$args = array('auid' => '0');
$ur_here .= ' > ' .
$GLOBALS['_LANG']['auction'] . '';
}

elseif ('snatch' == $filename)
{
$page_title = $GLOBALS['_LANG']['snatch'] . '_' . $page_title;
$args = array('id' => '0');
$ur_here .= ' > ' . $GLOBALS['_LANG']['snatch_list'] . '';
}

elseif ('wholesale' == $filename)
{
$page_title = $GLOBALS['_LANG']['wholesale'] . '_' . $page_title;
$args = array('wsid' => '0');
$ur_here .= ' > ' .
$GLOBALS['_LANG']['wholesale'] . '';
}

elseif ('exchange' == $filename)
{
$page_title = $GLOBALS['_LANG']['exchange'] . '_' . $page_title;
$args = array('wsid' => '0');
$ur_here .= ' > ' .
$GLOBALS['_LANG']['exchange'] . '';
}

}
}


if (!empty($str))
{
$page_title = $str . '_' . $page_title;
$ur_here .= ' > ' . $str;
}


return array('title' => $page_title, 'ur_here' => $ur_here);
}
