加载index.php中的空css文件

Question

从HTML中划分PHP代码的方式。我在加载css文件时遇到了问题。 所以我有php文件index.php，css文件 - main.css和html文件front.html和log_in.html

<?php

// Get email address
require_once 'config.php';

// Ensures no one loads page and does simple spam check
if(isset($_POST['name']) && empty($_POST['spam-check'])) {

    // Declare our $errors variable we will be using later to store any errors
    $error = '';

    // Setup our basic variables
    $input_name = strip_tags($_POST['name']);
    $input_email = strip_tags($_POST['email']);
    $input_subject = strip_tags($_POST['subject']);
    $feedback = array(1 => "Volvo", 2 => "Saab", 3 => "Mercedes", 4 => "Audio");
    $feedback = $feedback[(int) $_POST['feedback']];
    $input_message = strip_tags($_POST['message']);

    // We'll check and see if any of the required fields are empty
    if(strlen($input_name) < 2) $error['name'] = 'Please enter your name.';
    if(strlen($input_message) < 5) $error['message'] = 'Please leave a message.';

    // Make sure the email is valid
    if(!filter_var($input_email, FILTER_VALIDATE_EMAIL) ) $error['email'] = 'Please enter a valid email address.';

    // Set a subject & check if custom subject exist
    $subject = "Message from $input_name";
    if($input_subject ) $subject .= ": $input_subject";

    $message = "$input_message\n";
    $message .= "\n---\nThis email was sent by contact form.";
    $feedback = "$feedback";

    // Now check to see if there are any errors 
    if(!$error) {

        // No errors, send mail using conditional to ensure it was sent
        if(mail($your_email_address, $subject, $message, "From: $input_email")) {
            echo '<p class="success">Your email has been sent!</p>';
        } else {
            echo '<p class="error">There was a problem sending your email!</p>';
        }

    } else {

        // Errors were found, output all errors to the user
        $response = (isset($error['name'])) ? $error['name'] . "<br /> \n" : null;
        $response .= (isset($error['email'])) ? $error['email'] . "<br /> \n" : null;
        $response .= (isset($error['message'])) ? $error['message'] . "<br /> \n" : null;

        echo "<p class='warning'>$response</p>";

    }

} else {

    die('Direct access to this page is not allowed.');

}

这里我尝试将登录容器放在front.html页面中。我最好这样做，创建另一个类似的页面。

如果我去目录localhost / my-site /（如果我理解正确，它会自动接受index.php或index.html） 它完美地向我展示了这个网站。一切正常。 但是一旦我得到localhost / my-site / index.php就会得到一个带有空css文件的页面（参见附图）。 所以问题是：它为什么会发生？它与localhost / my-site /和localhost / my-site / index.php的地址不一样吗？

Answer 1

如果输入localhost / site-final / index.php（没有/结尾）会发生什么？我认为当你有index.php /时，它会尝试加载localhost / site-final / index.php / css / main.css。您可以使用css文件的绝对路径（http://localhost/site-final/css/main.css）。
