将输入类型文本放入数组中 [英] put input type text in an array

问题描述

我有一些文字输入。 输入从产生，而循环产生。现在我想将值放入一个数组中。像这样：

I have some text inputs. The inputs are produced from a while loop. Now I want put the values in an array. Like this:

array       values
mark['0']   input1
mark['1']   input2
mark['2']   input3

我试过这个但不工作。 <$ p
$ b

I tried this but not working.

while($row=mysql_fetch_array($result)){
  <form class="form1" name="form1" method="post">
    <input type="text" name="mark[]"/>
  </form>
}
<form class="form1" name="form1" method="post">
    <button type="submit" name="correction"></submit>
</form>

然后

And then

if(isset($_POST['correction'])){
$grade=0;   
    $mark=$_POST['mark'];
    foreach($mark as $key =>$value ){
        $grade+=$value;
    }   
print $grade;
}

我收到这些错误：

I get these errors:

Notice: Undefined index: mark in C:\xampp\htdocs\virtual_exam\handy_correction.php on line 37

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\virtual_exam\handy_correction.php on line 38

问题可能是由两种不相互连接的表单造成的，如果是，如何加入？
如果没有，如何做我想要的？

The problem may be caused by two forms which arent connected to each other and if YES, how to joined them? If NO, how to do what i want?

推荐答案

将您的表单更改为：

<form class="form1" name="form1" method="post">

  <?php
    while ($row = mysql_fetch_array($result)) {
      echo '<input type="text" name="mark[]" />';
    }
  ?>

  <input type="submit" name="correction" value="Submit" />
</form>

然后：

And then:

if (isset($_POST['correction'])) {
  $grade = 0;   
  $mark  = $_POST['mark'];

  foreach ($mark as $key => $value) {
    $grade += $value;
  }

  echo $grade;
}
