<select name="gender">
<option value="1" selected <?= ($_POST['gender'] == "1")? "selected":"";?>>Select</option>
<option value="male" <?= ($_POST['gender'] == "2")? "selected":"";?>>Male</option>
<option value="female" <?= ($_POST['gender'] == "3")? "selected":"";?>>Female</option>

if (isset($_POST['submit'])) {
$gender = $_POST['gender'];
if($gender != "2" || $gender != "3"){
$msg_gender = "Gender not valid";
}
}
如果 $msg_gender="" 表格將是有效的，否則它會說性別無效。但它說無論我選擇哪個選項，每個階段的性別都無效
uj5u.com熱心網友回復：
您的值不是 3 或 2，而是“男性”或“女性”，因此您必須將您的條件更改為
if($gender != "male" || $gender != "female"){
$msg_gender = "Gender not valid";
}
或更改您的選項值
<option value="2" <?= ($_POST['gender'] == "2")? "selected":"";?>>Male</option>
<option value="3" <?= ($_POST['gender'] == "3")? "selected":"";?>>Female</option>
uj5u.com熱心網友回復：
將您的代碼更改為：
if($gender != "female" || $gender != "male"){
$msg_gender = "Gender not valid";
}
選項值是實際發送的

<?php

foreach($_POST as $k=>$v){$$k=$v;}
if(isset($_POST['submit'])) {
$gender = $_POST['gender'];
if($gender == "male" or $gender == "female"){
$msg_gender = "Selected ".$gender;
}
else

$msg_gender = "Gender not valid";
