[英]How can I make a submenu
I have the next database: 我有下一个数据库:
I have the below function: 我有以下功能:
<?php
$connection = mysql_connect("localhost", "root", "password") or die(mysql_error());
mysql_select_db("database1", $connection) or die(mysql_error());
function loop_array($array = array(), $parent_id = 0)
{
if (!empty($array[$parent_id])) {
echo '<ul>';
foreach ($array[$parent_id] as $items) {
echo '<li>';
echo '<a href="?page='.$items['id'].'">'.$items['title'].'</a>';
loop_array($array, $items['id']);
echo '</li>';
}
}
}
function displays_menus_revised()
{
$sql = "SELECT * FROM pages";
$query = mysql_query($sql) or die(mysql_error());
$array = array();
if (mysql_num_rows($query)) {
while ($rows = mysql_fetch_array($query)) {
$array[$rows['parent_id']][] = $rows;
}
loop_array($array);
}
}
?>
My problem is the funtion show the records like in the left picture. 我的问题是功能类似于左图所示显示记录。 I want the function to show the records like in the right picture.
我希望该功能显示记录如右图所示。 Can you tell me where is the problem?
你能告诉我问题出在哪里吗? What i must change that the function show records like in the right picture?
功能如右图所示记录我必须更改什么? Thanks.
谢谢。
So nice code, with such a small slip. 这么小的代码,代码真好。 Only the closing 'ul' is missing.
仅缺少结尾的“ ul”。
function loop_array($array = array(), $parent_id = 0)
{
if (!empty($array[$parent_id])) {
echo '<ul>';
foreach ($array[$parent_id] as $items) {
echo '<li>';
echo '<a href="?page='.$items['id'].'">'.$items['title'].'</a>';
loop_array($array, $items['id']);
echo '</li>';
}
echo '</ul>';
}
}
