Question

HTML CODE HERE

php代码中的for循环有些错误

 <html>
 <head><title>Hello
  </title></head>
   <body>
     <form id="cool" name ="form" action ="hi.php">
      <input type ="text" name="m1" value="m1"/>
          </br><input type ="text" name="m2" value="m2">
          </br><input type ="text" name="m3" value="m3">
          </br><input type ="text" name="m4" value="m4">
          </br><input type ="text" name="m5" value="m5">
          <input type="submit" >
         </form>
         </body>
         </html>

这是php代码，它在第6行显示未定义的索引，此处mem获取值m1，m2，m3，m4，但从mem中提取值不起作用

<?php

for ($i = 1; $i < 5; $i++) {
    $mem = 'm' . $i;

    $m = $_POST[$mem];
    print " The member is" . $m . "</br>";
}
?>

Answer 1

您需要在表单标记中添加ident = TRUE;

method="POST"

Answer 2

使用此<form id="cool" name ="form" action ="hi.php" method="post">

代替 <form id="cool" name ="form" action ="hi.php">

无法将变量值分配给另一个变量
