使用PHP+;HTML
我正在为一家医院做一个系统,我目前正在做的模块是病人账单的交易/计算。我在一个带有复选框的页面中列出了所有费用。提交时如何计算这些值使用PHP+;HTML,php,html,Php,Html,我正在为一家医院做一个系统,我目前正在做的模块是病人账单的交易/计算。我在一个带有复选框的页面中列出了所有费用。提交时如何计算这些值 <?php $mysql_hostname = "localhost"; $mysql_user = "root"; $mysql_password = ""; $mysql_database = "hmis"; $bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die
