无法使用内部连接获取插入的 ID

Question

这里有一个简单的代码，我使用了 2 个带有显示和隐藏的表单，所以一切都很好，我只是错过了使用第二种表单在不同的桌子上设置 CL_ID

所以我在这里需要什么只是插入该行结果.$row['cl_id']. 我在第一个查询中得到的内容被插入到第二个表单中什么是正确的并保存了数据' 我试过把它调高或调低我的所有问题都是($row= mysql_fetch_assoc($data))的“未定义变量”和其他“未定义索引”原因@

我尝试了所有方法，但我发现定义了它应该是的变量 ($row= mysql_fetch_assoc($data)) { only here } 数组未达到的任何其他地方不可读

<?php
echo"<style type='text/css'>#here{ display:none; } </style> ";
require ('connections.php');
echo"<hr />";
if(isset($_POST['search'])) {
   $search=(trim($_POST['search']));
   if (empty($search)){echo" insert something to search it ";
   } else{
     $data=mysql_query("SELECT * from cl_info INNER JOIN cl_pro ON cl_pro.cl_id=cl_info.id WHERE cl_info.id LIKE '$search'")or die(mysql_error());
     $num=mysql_num_rows($data);
         if($num<1){echo' no results of your search'; }

        else{?> <style type="text/css">#form1{ display:none; }</style>
                <style type="text/css">#here{ display:block; }</style>
        <?php




              while ($row= mysql_fetch_assoc($data)) {
                //$ak=($row['cl_id'])   ;
//                    echo("<hr/>");
//                     echo("$ak");

 echo("<table with='40%'border='1' align='center'>

好的，试试这个：

 mysql_query ("INSERT INTO scri (id, cl_id, r, doze, time, date) VALUES ('', '$ak', '$r', '$doz', '$t', '$date')")or die ( mysql_error());

这对我有用:)
