ecshop classification tree displays solutions for all categories. Friends in need can refer to this article.
The solution is as follows:
For example, in goods.php,
| 代码如下 |
复制代码 |
| $smarty->assign('categories', get_categories_tree()); // 分类树 |
About line 128. Just look for it
Will
The code is as follows
| 代码如下 |
复制代码 |
$smarty->assign('categories', get_categories_tree($goods['cat_id']));
|
|
Copy code
|
$smarty->assign('categories' , get_categories_tree($goods['cat_id']));
| 代码如下 |
复制代码 |
| $smarty->assign('categories', get_categories_tree()); |
changed to
The main thing is to remove goods['cat_id'] or the obtained ID!
Afterwards clear the cache and check the frontend to see if it has changed
| 代码如下 |
复制代码 |
if ($cat_id > 0)
{
$sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$cat_id'";
$parent_id = $GLOBALS['db']->getOne($sql);
}
else
{
$parent_id = 0;
} |
Note: Only half of the solution has been solved here. You still need to perform the same operation in category.php so that all categories are displayed on the category page.
An easier way is to modify the get_categories_tree function, which was reminded by the water god. Modify as follows:
| The code is as follows
|
Copy code |
| if ($cat_id > 0) |
{
$sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$cat_id'";
$parent_id = $GLOBALS['db']->getOne($sql);
}
else
{
$parent_id = 0;
}
Find this judgment statement, comment it out, and add
// Add settings to read out all categories
$parent_id = 0;
