当我们通过for循环提供输入字段时如何填充数据库表？

<?php 
mysql_connect('localhost','root',''); 
mysql_select_db('filters'); 
$select_no=""; 
?> 
<!DOCTYPE html> 
<html> 
<head> 
    <title> filters program</title> 
</head> 
<body> 
<form method="POST" action=""> 
    Select No. OF Fields <input type="number" style="width:100px;border- radius:10px;" id="selct_no" name="select_no" value=""> To <input type="submit" name="create" id="create_fields" value="create" style="width:70px;border-radius:10px;" onclick="createFields()"> <br><br> 

     <?php 
     //IF CONDIOTIN FOR CREATIG ITEMS FIELD depend on user need.... 
     if(isset($_POST['create'])){ 
      $select_no=$_POST['select_no']; 
     //FOR loop for creating fileds... 
     // loop for generating given no. of fields... 
      for ($i=0; $i < $select_no ; $i++) { 
       global $x; 
       $x = $i+1; 

       echo $x.'.) Enter Products Name and Prices.... <br>' ; 
       echo "<input type='text' style='width:300px; height:25px; border-radius:10px;' placeholder='Enter Items' id='id_item' name='items".$x."' value=''> <input type='text' style='width:100px;height:25px; border-radius:10px;' placeholder='Price' id='id_price' name='price".$x."' value=''> <br/><br/> "; 
     }  
     echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<button name='submit'      
        style='width:300px;height:25px;border-radius:10px'  id='submit_cat'>submit</button>"; 
     echo "<br><No of created fields are ".$x; 

} 
     //if condition for saving data in database table name filters and table name products.... 
     if(isset($_POST['submit'])){ 
      global $x; 
      for ($a=1;$a<=$x;$a++){ 
       $product=$_POST["items".$a]; 
       $price=$_POST["price".$a]; 
       echo "$product"; 
       echo "$price"; 
       $sql= "INSERT INTO products SET  product='$product',price='$price'"; 
       $res=mysql_query($sql); 
       if ($res) { 
       echo " data submitted Successfully"; 
       }else{ 
       echo "Not submitted because ".mysql_error();} 
     } 
    } 


?> 

</form> 
</body> 
</html>

在这里，我想那是什么，有些哥们请什么概念我会让人口稠密，在我的数据库表中的信息的每一个细节当我们通过for循环提供输入字段时如何填充数据库表？

这里我提供snapeshot也为你的理解告诉我... .. this is the first view when we enter value it will creat fields in this image 4 fields are created when we press (create) button after enter 4 in first input field

无效的插入查询。请查看在mysql中插入查询的语法 –

你在插入查询错误，表格这样

INSERT INTO table_name 
(column1,column2,column3,...) 
    VALUES (value1,value2,value3,...);

编辑：问题是与全局变量，丢失的形式输入查询，这里是工作的解决方案：

<html> 
     <head> 
      <title> filters program</title> 
     </head> 
     <body> 
      <?php 
      //if condition for saving data in database table name filters and table name products.... 
      if(isset($_POST['name_s'])){ 
       session_start(); 
       $x = $_SESSION["number_of_x"]; 
       for ($a=1;$a<=$x;$a++){ 
        $product=$_POST["items".$a]; 
        $price=$_POST["price".$a]; 
        echo "$product"; 
        echo "$price"; 
        $sql= "INSERT INTO products (product, price) VALUES('$product','$price')"; 
        $res=mysql_query($sql); 
        if ($res) { 
        echo " data submitted Successfully"; 
        }else{ 
        echo "Not submitted because ".mysql_error();} 
       } 
      }else{ 
      ?> 
       <form method="POST" action="#"> 
        Select No. OF Fields <input type="number" style="width:100px;border- radius:10px;" id="selct_no" name="select_no" value=""> To <input type="submit" name="create" id="create_fields" value="create" style="width:70px;border-radius:10px;" onclick="createFields()"> <br><br> 
       </form> 
      <?php 
      } 
      //IF CONDIOTIN FOR CREATIG ITEMS FIELD depend on user need.... 
      if(isset($_POST['create'])){ 
       $select_no=$_POST['select_no']; 
       // Start the session 
       session_start(); 
       $_SESSION["number_of_x"] = $_POST['select_no']; 
      //FOR loop for creating fileds... 
      // loop for generating given no. of fields... 
      ?> 
      <form method="POST" action="#"> 
      <?php 
       for ($i=0; $i < $select_no ; $i++) { 
        global $x; 
        $x = $i+1; 

        echo $x.'.) Enter Products Name and Prices.... <br>' ; 
        echo "<input type='text' style='width:300px; height:25px; border-radius:10px;' placeholder='Enter Items' id='id_item' name='items".$x."' value=''> <input type='text' style='width:100px;height:25px; border-radius:10px;' placeholder='Price' id='id_price' name='price".$x."' value=''> <br/><br/> "; 
       }  
      ?> 
       <input type="submit" name='name_s' style='width:300px;height:25px;border-radius:10px'  id='submit_cat'></input>"; 
      </form> 
      <?php 
      } 
      ?> 
     </body> 
    </html>

希望这有助于。

ohke thanku先生我会尝试这个查询... 非常感谢... –

actully先生它的我的错误，我没有看到我的代码发布之前有在我的两个注释之间代码我错过这两个线路如下所示 '// IF CONDIOTIN FOR CREATIG ITEMS领域.... 如果（isset（$ _ POST [ '创建']））{ $ select_no = $ _ POST [ 'select_no']; // for循环建立的Fileds ...' 和问题是，它在我的鳕鱼不会进入'如果（isset（$ _ POST [ '提交']））{}' 洙请帮助我，在此先感谢..... –

事情是你的提交按钮没有做任何事情，因为我可以看到，你需要创建
