Question

我的数据库中的所有内容都会填充，但实际图像本身除外。我已经看了好几个小时了，我似乎无法弄清楚为什么当我点击提交时我仍然会收到这些错误。虽然我得到错误的其他信息;大小，类型，名称确实显示在我的数据库中。请帮忙。这是我的代码。

<?php
ob_start();
?>

<?php

session_start();
if($_SESSION['nachos'] != "admin")
header("Location: index.php");



?>

       $image = mysqli_real_escape_string($dbConnection, $image);

        mysqli_query($dbConnection, "INSERT INTO portfolio (title, shortDescription, longDescription, image, imageName, imageType, imageSize) VALUES ('$_POST[txtTitle]', '$_POST[txtShortDescription]', '$_POST[txtLongDescription]', '$image', '"  . $_FILES['imgPhoto']['name'].

        echo "</fieldset></form>" ;

        }

        ?>

        </div>

这些是我得到的错误。虽然我仍然可以获取其他字段的数据，但是图像设置为blob并且它从不加载它。

警告：fopen（）[function.fopen]：第100行/home/wequpstu/public_html/admin/portfolioForm.php中的文件名不能为空

警告：fread（）要求参数1为资源，布线在第101行的/home/wequpstu/public_html/admin/portfolioForm.php中给出

警告：fclose（）要求参数1为资源，第102行/home/wequpstu/public_html/admin/portfolioForm.php中给出布尔值

Answer 1

错字错误tmpName =＆gt; tmp_name

    $handle = fopen($_FILES['imgPhoto']['tmp_name'], "r");
    $image = fread($handle, filesize($_FILES['imgPhoto']['tmp_name']));

Answer 2

错误很明显：$ _FILES ['imgPhoto'] ['tmpName']在

中为空

    $handle = fopen($_FILES['imgPhoto']['tmpName'], "r");

PHP代码无法使用我的数据库
