我希望有一个动态菜单,使用php和mysql从表中提供。
我的表格如下:
sec_id sec_name sec_group
1 section 1 group 1
2 section 2 group 1
3 section 3 group 2
4 section 4 group 1
5 section 5 group 3
我可以进行查询以获取并显示唯一的sec_group值,但无法找到将sec_name包含到每个sec_group中的方法
//Query by unique sec_group
$qry_secs="SELECT DISTINCT sec_group FROM tbl_user_sec ORDER BY sec_id ASC";
$result_secs = mysql_query($qry_secs);
//echo values
while($row_secs = mysql_fetch_assoc($result_secs)){
echo '<ul><li><a href="#">'.$row_secs['sec_group'].'</a></li></ul>';
}
最终,HTML应该像下面的代码一样。
<ul>
<li><a href="#">Group 1</a>
<ul>
<li><a href="#">Section 1</a></li>
<li><a href="#">Section 2</a></li>
<li><a href="#">Section 4</a></li>
</ul>
</li>
<li><a href="#">Group 2</a>
<ul>
<li><a href="#">Section 3</a></li>
</ul>
</li>
<li><a href="#">Group 3</a>
<ul>
<li><a href="#">Section 5</a></li>
</ul>
</li>
</ul>
任何想法?

$q = mysql_query("SELECT sec_id, sec_name, sec_group FROM tbl_user_sec ORDER BY sec_id");
// prepare data
$groups = Array();
while($w = mysql_fetch_assoc($q)) {
if(!isset($groups[$w['sec_group']])) $groups[$w['sec_group']] = Array();
$groups[$w['sec_group']][] = $w;
}
// display data
echo "<ul>";
foreach($groups as $group_name => $sections) {
echo '<li><a href="#">'.$group_name.'</a><ul>';
foreach($sections as $section) {
echo '<li><a href="#">'.$section['sec_name'].'</a>';
}
echo '</ul></li>';
}
echo "</ul>";
如果您不关心按sec_id

$qry_secs="SELECT DISTINCT sec_group FROM tbl_user_sec ORDER BY sec_id ASC";
$result_secs = mysql_query($qry_secs);
echo '<ul>\n';
//echo values
while($row_secs = mysql_fetch_assoc($result_secs)) {
echo '<li><a href="#">'.$row_secs['sec_group'].'</a></li>\n';
echo '<ul>\n';
$newqry = "SELECT sec_name FROM tbl_user_sec WHERE `sec_group` = '" . mysql_real_escape_string($row_secs['sec_group'] . "'";
$result = mysql_query($newqry);
while($row = mysql_fetch_assoc($result) ) {
echo '<li><a href="#">' . $row['sec_name'] . '</li>\n';
echo '</ul>\n';
}
echo '</ul>\n';
