网站不支持FireFox，但适用于Safari和Chrome

我创建了一个简单的网站，允许用户销售商品，然后查看待售商品列表。它在Safari和Chrome中完美运行，但它不适用于FireFox。我只是在测试期间遇到过这种情况。我将发布输入表单和处理php的代码，然后是我在Firefox中获得的错误。

FORM：

<?php
// Define variables and set to empty values
$titleErr = $descriptionErr = $priceErr = $quantityErr = $durationErr = $locationErr = "";
$title = $description = $price = $quantity = $duration = $location = "";
$valid = FALSE;

if ($_SERVER["REQUEST_METHOD"] == "POST") {
$valid = TRUE;

if (empty($_POST["title"])) {
    $titleErr = "Title is required";
    $valid = FALSE;
} 
else {
    $title = test_input($_POST["title"]);
}

if (empty($_POST["description"])) {
    $descriptionErr = "A description is required";
    $valid = FALSE;
} 
else {
    $description = test_input($_POST["description"]);
    if (!preg_match("/^[a-zA-Z ]*$/", $description)) {
        $descriptionErr = "Only letters and white space allowed";
    }
}

if (empty($_POST["price"])) {
    $priceErr = "A price is required";
    $valid = FALSE;
} 
else {
    $price = test_input($_POST["price"]);
}

if (empty($_POST["quantity"])) {
    $quantityErr = "A quantity is required";
    $valid = FALSE;
} 
else {
    $quantity = test_input($_POST["quantity"]);
}


if (empty($_POST["duration"])) {
    $durationErr = "Duration is required";
    $valid = FALSE;
} 
else {
    $duration = test_input($_POST["duration"]);
}


if (empty($_POST["location"])) {
    $locationErr = "A location is required";
    $valid = FALSE;
} 
else {
    $location = test_input($_POST["location"]);
}


// If valid then redirect
if($valid){
    header('Location: sell_your_item.php');
    exit();
}
}

// Function to remove spaces, strip slashes and allow special characters to be used in form
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;

答案 0 :(得分：0)

您可以直接将数据发布到sell_your_item.php，而不是将其发布到同一页面并执行所有检查并以其可行的方式保存数据。目前您只是重定向到页面但数据未传递给页面。
