我必須從數據庫中獲取主類別,子級,子級等。得到了主類和子類,但是沒有得到foreach循環外的subchild。在循環內部獲取了正確的值。我爲此使用了下面的代碼...我已經在$ children_data = array()後面聲明瞭$ sub_childs = array(),但是後來我在browswer中獲得了空白頁面。任何人都請幫忙。感謝ü數組值沒有得到外部foreach循環
$this->load->model('catalog/category');
$this->load->model('catalog/product');
$this->data['categories'] = array();
$categories = $this->model_catalog_category->getCategories(0);
foreach ($categories as $category) {
if ($category['top']) {$sub_childs = array();
$children_data = array();
$children = $this->model_catalog_category->getCategories($category['category_id']);
foreach ($children as $child) {
$sub_childs = array();
$sub_child = $this->model_catalog_category->getCategories($child['category_id']);
// echo '<pre>'; print_r($children_child);// got the correct values in here
foreach ($sub_child as $c_child) {
$data = array(
'filter_category_id' => $c_child['category_id'],
'filter_sub_category' => true
);
if ($this->config->get('config_product_count')) {
$product_total = $this->model_catalog_product->getTotalProducts($data);
$c_child['name'] .= ' (' . $product_total . ')';
}
$sub_childs[] = array(
'name' => $c_child['name'],
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'] . '_' . $c_child['category_id'])
);
}
//echo '<pre>'; print_r($sub_childs);// here also got it
$data = array(
'filter_category_id' => $child['category_id'],
'filter_sub_category' => true
);
if ($this->config->get('config_product_count')) {
$product_total = $this->model_catalog_product->getTotalProducts($data);
$child['name'] .= ' (' . $product_total . ')';
}
$children_data[] = array(
'name' => $child['name'],
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])
);
echo '<pre>'; print_r($sub_childs);
}
//echo '<pre>'; print_r($sub_childs);
// Level 1
$this->data['categories'][] = array(
'name' => $category['name'],
'children' => $children_data,
'child' => $sub_childs, // didn't get here
'column' => $category['column'] ? $category['column'] : 1,
'href' => $this->url->link('product/category', 'path=' . $category['category_id'])
);
}
