Question

我有一个您上传文件的页面。当你继续时，它说$ _POST没有设置（手动检查）。代码：

HTML（myCabinet.php）：

<?php

    include_once 'include/check.php';   

?>


<html>
<head>
<title>TNet - My Cabinet</title>
<script type="text/javascript" src="/js/jquery.js" charset="utf-8"></script>
<style>
#topHeaderText {

    font-family: Comic Sans MS;
    font-size: 36px;
    color: #FFFFFF;
    margin-left: 10px; 
    margin-bottom: 25px;

}

.topHeader {

    text-align: left;
    position: relative;
    top: 5px;
    width: 1900px;
    height: 48px;

}

#bottomHeaderText {

    font-family: Comic Sans MS;
    font-size: 24px;
    color: #FFFFFF;
    margin-bottom: 25px;

}

.bottomHeader {

    text-align: center;

    margin-top: 36px;

}

#settingsTitle {

    margin-left: 24px;
    font-family: Comic Sans MS;
    font-size: 36px;

}

#settingsSetup {

    font-size: 16px;
    color: #FFFFFF;

}

.file {

PHP（applySettings.php）：

<?php

session_start();

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

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

        include_once 'include/dbcon.php';
        $imageData = mysql_real_escape_string(file_get_contents($_FILES["pimg"]["tmp_name"]));
        $imageType = mysql_real_escape_string($_FILES["pimg"]["type"]);
        $imgInfo = getimagesize($_FILES["pimg"]["tmp_name"]);

        echo "Hello";

        /*
        if (substr($imageType, 0, 5) == "image" && $imgInfo[0] == 128 && $imgInfo[1] == 128) {

            $query = mysql_query("UPDATE users_id SET image = '".$imageData."' WHERE username = ".$_SESSION['login']."'");
            if (!$query) {

                header('Location: /error/error.php?mysql_query_failed');
                die();

            }

            $_SESSION['image'] = $imageData;

            header('Location: myCabinet.php');
            die();

        } else {

            header('Location: /error/error.php?incorrectFileFormat');
            die();

        }

        */

    } else {

        echo "Is not set!";

    }

} else {

    echo "Submit not set!";

}


?>

非常感谢帮助。如您所见，我的enctype是 multipart / form-data 。 POST_MAX_SIZE = 32M UPLOAD_MAX_SIZE = 32M

Answer 1

<input type="file" class="file" name="pimg">使用$ _FILES变量提交，可以在 applySettings.php 文件中访问。所以，数据看起来像这样

print_r（$ _ FILES）将打印：

Array
(
    [pimg] => Array
        (
            [name] => v2.jpg
            [type] => image/jpeg
            [tmp_name] => C:\bin\xampp\tmp\phpA63B.tmp
            [error] => 0
            [size] => 8447
        )

)

所以，你的代码会改变

<?php
session_start();
if (isset($_POST['submit'])) {
    if (isset($_POST['pimg'])) {

要

<?php
session_start();
if (isset($_POST['submit'])) {
    if (isset($_FILES['pimg'])) {

希望，它可以帮助你

上传时$ _POST和$ _FILES为空（甚至1 KB）
