如何在一个表格中包含多个变量

Question

这是我到目前为止的内容：

Age: <input type="text" name="age">

   Canoe<input type="radio" name="ck">
        Kayak<input type="radio" name="ck">


<input type="submit" style=" margin-bottom: 30px;">
</form>

You are <?php $_POST["age"];
 if ($_POST["age"]<"11")
 echo "an Atom.";

 elseif ($_POST["age"]<"13")
 echo "a Peewee.";

 elseif ($_POST["age"]<"15")
 echo "a Bantam.";

 elseif ($_POST["age"]<"17")
 echo  "a Midget.";

 elseif ($_POST["age"]<"19")
 echo "a Juvenile.";

 elseif ($_POST["age"]<"21")
 echo "a Junior.";

 elseif ($_POST["age"]<"120")
 echo "a Senior.";

 elseif ($_POST["age"]>"120")
 echo "too old to race";
   ?>   

我希望能够在其中包含独木舟和皮划艇单选按钮，以使输出像：您是Peewee皮划艇运动员，而今年的对手是：| 或者，您是小型皮划艇运动员。 您今年的对手是：

Answer 1

您是否要在输出中回显CK值？ 这有帮助吗？

Age: <input type="text" name="age">

Canoe<input type="radio" name="ck" value="canoeist">
Kayak<input type="radio" name="ck" value="kayakist">

<input type="submit" style=" margin-bottom: 30px;">
</form>

<?php
        $ck = $_POST["ck"];
?>

You are <?php $_POST["age"];
if ($_POST["age"]<"11")
echo "a $ck Atom.";

elseif ($_POST["age"]<"13")
echo "a $ck Peewee.";

elseif ($_POST["age"]<"15")
echo "a $ck Bantam.";

elseif ($_POST["age"]<"17")
echo  "a $ck Midget.";

elseif ($_POST["age"]<"19")
echo "a $ck Juvenile.";

elseif ($_POST["age"]<"21")
echo "a $ck Junior.";

elseif ($_POST["age"]<"120")
echo "a $ck Senior.";

elseif ($_POST["age"]>"120")
echo "too old to race";
?>

radio形式的值必须是“划独木舟”和“ kayakist”。 只需添加$ck = $_POST['ck']; 您的句子就像echo "a $ck Atom.";

Answer 2

您应该在此处使用一些变量。

（我不太擅长php，但我会尝试一下）

Age: <input type="text" name="age">

    Canoe<input type="radio" name="ck" value="canoe"/>
    Kayak<input type="radio" name="ck" value="kayak"/>

<input type="submit" style=" margin-bottom: 30px;">
</form>

$boat = "";
if ($_POST["ck"] == "canoe")
{
    $boat = "canoeist";
} else if ($_POST["ck"] == "kayak")
{
    $boat = "kayak er";
}


$rank = "";
You are <?php $_POST["age"];
 if ($_POST["age"]<"11")
 $rank = "an Atom.";

 elseif ($_POST["age"]<"13")
 $rank = "a Peewee.";

 elseif ($_POST["age"]<"15")
 $rank = "a Bantam.";

 elseif ($_POST["age"]<"17")
 $rank =  "a Midget.";

 elseif ($_POST["age"]<"19")
 $rank = "a Juvenile.";

 elseif ($_POST["age"]<"21")
 $rank = "a Junior.";

 elseif ($_POST["age"]<"120")
 $rank = "a Senior.";

 elseif ($_POST["age"]>"120")
 $rank = "too old to race";

 echo "You are " . $rank . " " . $boat;
   ?>
