我想做的是：
当我选择组合框项目时，从数据库中获取项目并显示我选择的所有标记。但它不起作用。
这是我的代码：
<?php
session_start();
$_SESSION['sum']=0;
include("database/connect_conf.php");
if(!connection()){
echo 'Not connect: '.mysql_error();
}else{
connection();
}
if(!db_select()){
echo 'Not connect to Dabatase: '.mysql_error();
}else{
db_select();
}
$string="SELECT count(province_id) AS c FROM tbl_cep_forum";
$get_result=mysql_query($string);
if($get_result){
$j=1;
while($value=mysql_fetch_array($get_result)){
$_SESSION['sum']=$_SESSION['sum']+$value['c'];
$j++;
}
}
?>

答案 0 :(得分：0)
您的第一个戏剧可能是您使用$.load()函数和$.post()函数通过jQuery调用相同的PHP脚本：
$('#t2').load('phpajax_get_uniq_province.php').show();
var get_name=$('#continent').val();
$.post('phpajax_get_uniq_province.php', { continent: get_name },
我毫不怀疑这是许多问题中的第一个。您确实需要将代码分割成碎片，独立运行它们，使用Firebug或类似方法查看交互，然后在证明每个段没有错误时将其组合。
