动态表单插入数据库

我的整个注册页面代码在这里。 Link

我尝试将此动态字段添加到注册页面代码中。

<script>

 var i = 1;
 function addKid(){
    if (i <= 6){
      i++;
 var div = document.createElement('div');
 div.style.width = "44%";
 div.style.height = "26px";
 div.style.color = "white";
 div.setAttribute('class', 'myclass');
 div.innerHTML = 'Child : <input type="text" name="child_'+i+'" > Ages : <input type="text" name="ages_'+i+'"><input type="button" id="add_kid()" onClick="addKid()" value="+" /><input type="button" value="-" onclick="removeKid(this)">';
 document.getElementById('kids').appendChild(div);
 }
 }
 function removeKid(div) {
     document.getElementById('kids').removeChild( div.parentNode );
 i--; }


         <div id="kids">
     Child : <input id="child_1" type="text" onfocus="emptyElement('status')" onkeyup="restrict('mwhen')" maxlength="50">

      Ages :  <input id="ages_1" type="text" onfocus="emptyElement('status')" onkeyup="restrict('mwhen')" maxlength="10"><input type="button" id="add_kid()" onClick="addKid()" value="+" />
       </div>

我可以得到＆＃34; child_1 / chi＆＃34;和＆＃34; ages_1 / ags＆＃34;插入我的数据库。没问题。

当我尝试在我的注册中创建一个额外的动态字段时，＆＃34; child_2和ages_2＆＃34; ..... 然后，我无法从＆＃34; child_2和age_2＆＃34;中获取该信息。插入我的数据库。

有人可以告诉我自己做错了什么，因为我无法将这些信息输入我的数据库。我想打电话给＃34; child_2 / chi2＆＃34;和＆＃34;年龄_2 / ags2＆＃34;对于els之前它会起作用。？

if(isset($_POST["u"])){
// CONNECT TO THE DATABASE
include_once("php_includes/db_conx.php");

请将您的孩子和年龄保存在数组中并将其传递给ajax。这样你就可以循环下面给出的孩子和年龄，并将其插入表格。

对于密码和符合密码，请使用js。并在前端验证它自己。在表格中单独保存密码就足够了。

尝试理解此代码并根据需要进行更改。但我解决了你充满活力的孩子和年龄问题。运行此代码

我在你的代码中注意到的另一件事。

$ sql =＆＃34; SELECT id FROM users WHERE username =＆＃39; $ u＆＃39;限制1＆＃34 ;;

$ sql =＆＃34; SELECT id FROM users WHERE email =＆＃39; $ e＆＃39;限制1＆＃34 ;;

你已经写了两个查询。把它作为给定的单身

$ sql =＆＃34; SELECT id FROM users WHERE email =＆＃39; $ e＆＃39;和用户名=＆＃39; $ u＆＃39;限制1＆＃34 ;;
