Question

我一直在寻找并试图找到我的代码有什么问题已经有一段时间了，如果我仍然不知道我的代码有什么问题，我就不会问这个问题。基本上我正在回复一个get表单，有一个php脚本，就像这样的动作：

<?php
//Add a team list and list members to each team.
$memq = "SELECT members.id, teams.team_name, teams.stage, teams.points, members.member1 FROM members INNER JOIN teams ON teams.team_name=members.team_name";
$memres = mysql_query($memq) or die ('Couldnt display members'.mysql_error());
echo "<br> Teams, Stage & Members: <br>";
while ($memrow = mysql_fetch_assoc($memres))
{
	$team_name = $memrow['team_name'];
	echo "<form method='get' action='addOne.php'><input type='hidden' name='team_name' value='$team_name'><input type ='submit' name='team_name' value='+1'></form> ";
	echo "<form method='get' action='addTwo.php?team_name=$team_name' value='<?php echo $team_name;?>'><button type ='submit'>+2</button></form> ";
	echo "<form method='get' action='addTen.php?team_name=$team_name' value='<?php echo $team_name;?>'><button type ='submit'>+10</button></form> ";
	echo $memrow['id'] . " | " . $memrow['team_name'] . " | " . $memrow['stage'] . " | " . $memrow['member1'] . " | " . $memrow['points'] . "<br>";
	
}
?>

我一直在玩它并尝试过各种各样的事情（在表单声明中有value =字段等等），但是当我在浏览器中检查检查器时，它说：

<form method="get" action="addOne.php?team_name=asda">
  <input type="hidden" value="asda">
  <input type="submit" value="+1"></form>

因此，您可以看到该值实际已设置，但表单提交必须无效，因为addOne.php（if）中的if (isset($_GET['team_name']))语句始终返回false。

我在这里错过了一些非常简单的东西吗？感谢提前感谢。：）

Answer 1

问题是您在表单的action属性中使用GET变量。如果你设置方法=＆＃39;得到＆＃39;以及在那里使用get变量的操作，它们将被删除并用表单中的变量覆盖。它应该遵循HTML：

<form method="get" action="addOne.php">
    <input type="hidden" name="team_name" value="asda">
    <input type="submit" value="+1">
</form>

并且PHP应如下所示：

＆＃13;

$team_name = $memrow['team_name'];
echo "<form method='get' action='addOne.php'><input type='hidden' name='team_name' value='$team_name'><input type ='submit' value='+1'></form> ";

＆＃13;

Answer 2

您需要将名称属性放在输入标记中，如下所示

  <div class="editor-field">
       @Html.EditorFor(model => model.message.Replace(Environment.NewLine, "<br/>")), new { rows = "6", cols = "500" })
       @Html.ValidationMessageFor(model => model.message)
  </div>

然后，cecibe值如：

<input type="hidden" name="var_1" value="asda" />

得到形式不传递值PHP
