php - How to update multiple mysql database rows with same field names? -

-

i'm trying update multiple rows share same field names.

the structure like:

+---+-------+--------+ |id | name  | value  | +---+-------+--------+ | 1 | color | red    | | 2 | fruit | apple  | | 3 | day   | friday | +---+-------+--------+

so, :

$config_data = "update system_config set color = '$_post[color]', fruit = '$_post[fruit]', day = '$_post[day]'";  $success = mysql_query($config_data);

... not work. how perform query?

try

$config_data = "update system_config set value = '$_post[color]' name = 'color';"; $success = mysql_query($config_data); $config_data = "update system_config set value = '$_post[fruit]' name = 'fruit';"; $success = mysql_query($config_data); $config_data = "update system_config set value = '$_post[day]' name = 'day'"; $success = mysql_query($config_data);

instead.it's necessary put in more queries in case
