我有这个功能只从db
中获取不同的值function get_all_product_data_admin()
{
$query = "SELECT DISTINCT category FROM products ORDER BY product_id AS";
mysql_query("SET NAMES 'utf8'");
$result = mysql_query($query);
if($result == false) //Something is wrong with the query
echo "result non";
if(mysql_num_rows($result) == 0) //No Pages
echo "result 0";
while($row = mysql_fetch_assoc($result)) // MAKES 2D ARRAY FOR DRAWING A LIST
{
$returned_array[] = $row;
}
return $returned_array;
}
这是html。我使用switch
,因此英文值将显示为希伯来语翻译。
$menu = get_all_product_data_admin();
foreach($menu as $key=>$val) {
switch($val['category'])
{
case "bread": $catt = "לחמים"; break;
case "buns": $catt = "לחמניות"; break;
case "bake": $catt = "מאפים"; break;
case "cake": $catt = "עוגות"; break;
case "cookies": $catt = "עוגיות"; break;
case "dessert": $catt= "קינוחים אישיים"; break;
case "pita": $catt = "פיתות"; break;
case "friday": $catt = "חלות יום ו"; break;
case "baget": $catt = "באגטים"; break;
case "jabeta": $catt = "ג'בטות"; break;
case "nogloten": $catt = "ללא גלוטן"; break;
case "holiday": $catt = "מוצרי חגים"; break;
case "special": $catt = "מיוחדים"; break;
}
echo '
<a style="float:right;" href="add_product.php?cname='.$val['category'].'">
'.$catt.'
</a>
';
}
我仍然有重复的价值观。任何人?
答案 0 :(得分:2)
使用Group by
SELECT category FROM products Group by category
GROUP BY语句与聚合函数结合使用,可以按一列或多列对结果集进行分组。
