Question

如果我选择水果并混合水果，它会显示lert "You have selected Fruit's favour and Fruit's topping, are you sure?" 但我的代码显示"You have selected chocolate's favour and chocolate's topping, are you sure?"

它不会去别的地方。

if(isset($_POST['submit'])){

    if($favour=="Chocolate"and $topping=="Chocolate Chip"){
        ?>
        <script type="text/javascript">
            if(window.confirm("You have selected chocolate's favour and chocolate's topping, are you sure?")) { alert("You have apply successfully");window.location="index.php";
            } else {
                window.location="customization.php";
            }
        </script>
        <?php
    }

    elseif($favour=="Fruit"and $topping=="Mix Fruit"){
        ?>
        <script type="text/javascript">
            if(window.confirm("You have selected Fruit's favour and Fruit's topping, are you sure?")) { alert("You have apply successfully");window.location="index.php";
            } else {
                window.location="customization.php";
            }
        </script>
    <?php
    }
else{
    $cakesize=$_POST['cakesize'];

    $favour=$_POST['favour'];
    $topping=$_POST['topping'];
    $color=$_POST['color'];
    $cmessage=$_POST['cmessage'];
    $cumessage=$_POST['customize_message'];
    $date=date("Y-m-d");
    ?>
    <script type="text/javascript">
        alert("You have apply successfully");
        window.location = "index.php"
    </script>
    <?php

    mysql_query("INSERT INTO customization (cakesize,cfavour,topping, ccolor, cmessage,customizeMessage, C_date, Member_ID,status) VALUES ('$cakesize','$favour' ,'$topping', '$color' ,'$cmessage','$cumessage', '$date', '$uname','pending')");
}
}

Answer 1

检查条件时，需要使用等于运算符：==

$favour=$_POST['favour'];
$topping=$_POST['topping'];

if($favour=="Chocolate"and $topping=="Chocolate Chip"){
    ?>
    <script type="text/javascript">
        if(window.confirm("You have selected chocolate's favour and chocolate's topping, are you sure?")) { alert("You have apply successfully");window.location="index.php";
        } else {
            window.location="customization.php";
        }
    </script>
    <?php
}

您还需要确保要检查的变量在之前设置为值。我编辑了上面的代码来反映这一点。

Answer 2

您正在撰写=而不是==。
