从php表单插入多行到数据库 [英] Inserting multiple rows from a php form into the database

问题描述

我的表格如下表(textfeild).我正在将这些价值观充实到这些文本中.如何将这些值输入数据库?请帮助.

my form as the following table (of textfeild). I am feeding the values into these textfeild. How can i enter these values into my database? plz help.

格式的代码:-

    $rows=$_POST["rows"];       
          echo "
        <table align=\"center\" border=\"1\" width=\"70%\">
        <tr>
        <td><b>Roll No.</b></td> <td><b>Full Name</b></td> <td><b>Unit_test</b>       </td><td><b>Prelims</b></td> 
        <td><b>Attendance</b></td> <td><b>File</b></td> 
        </tr>";

    for($n=0;$n<$rows;$n++)
    { 
    echo "<tr>
    <td><input type=\"text\" name=\"roll\" /></td><td><input type=\"text\"                 name=\"name\" /></td><td><input type=\"text\" name=\"unit_test\" /></td>
    <td><input type=\"text\" name=\"prelims\" /></td><td><input type=\"text\"  name=\"attendance\" /></td><td><input type=\"text\" name=\"file\" /></td>
    </tr>";
    }
     echo "</table>";
     echo "<form action=\"feed2.php\" method=\"post\">
    <br>
     <input type=\"submit\" name=\"\" value=\"Submit\" />
   </form>";

用于插入db的代码:-

code used for inserting into db:-

for($n=0;$n<3;$n++)
{
  if(isset($_POST['roll']))
  {
    echo "<br>Updating";

    $roll=$_POST['roll'];
    $name=$_POST['name'];
    $unit_test=$_POST['unit_test'];
    $prelims=$_POST['prelims'];
    $attendance=$_POST['attendance'];
    $file=$_POST['file'];

    $sql="Insert into students (roll,name,unit_test,prelims,average,attendance,file,interm) 
    VALUES ('$roll','$name','$unit_test','$prelims','$average'=(('$unit_test' + '$prelims')/125) *10,'$attendance','$file','$average'+'$attendance'+'$file')";
    $res=mysql_query($sql);
    header("Location:./view.php");
  } 

推荐答案

最简单的方法可能是使roll等的$ _POST值成为一个数组(因此$ _POST成为多维数组).

The simplest way is probably to make the $_POST values for roll etc. an array (so $_POST becomes a multidimensional array).

请参见前面的问题，以获取有关如何完成此操作的示例:

See this previous question for an example of how it can be done:

通过POST使用php提交多维数组

然后您可以遍历数据库插入代码中的数组值.

You can then loop through the array values in your database insert code.
