使用php，mysql登记表

Question

在我的登记表格中，所有字段都可以正常工作，但村庄字段在数据库中返回0。

我用ajax和jquery为省和地区和村庄创建了一个下拉列表。

第2做工精细，但村里没有将任何东西

我不知道要显示的内容chunck的代码，以使人们了解我，所以我没有显示整个代码

这是代码

register.php

<?php require_once('for members/scripts/connect.php'); ?> 



<?php 
function specializationQuery(){ 

$specData = mysql_query("SELECT * FROM specialization"); 

    while($recordJob = mysql_fetch_array($specData)){ 

    echo'<option value="' . $recordJob['specialization_id'] . '">' . $recordJob['specialization_name'] . '</option>'; 

    } 


}

@ user2326255请检查您从下拉列表中村。在html中你已经设置了0选项。如果用户不选择村庄，则默认值将被发送。代码

if($village == "") 
{ 
$message = $message . "Select Your Village<br />"; 

} 

更改为

if($village == '0') 
    { 
    $message = $message . "Select Your Village<br />"; 

    } 

如果用户不选择村那么我们就需要告诉请村里的用户。上面的代码更改会向用户抛出错误。
