Question

我试图制作一个简单的上传表单，将图片上传到我的本地服务器，它确实有效，但问题是有些图片（JPG型）无法读取。我不知道问题所在。

处理表格的代码：

    <form id="addPTK" method="post" action="scripts/php/addPTK.php" enctype="multipart/form-data">
<table cellpadding="3px">
    <tr>
        <td>
            <div style="margin-bottom:10px;">
                <img id="noPic" src="images/contains/no-pic.jpg" style="width:148px;height:188px;border:2px solid #000" ><br>
                <input type="file" name="picPTK" style="width:55%" onchange="readURL(this)" />
                <script type="text/javascript">
                    function readURL(input) {
                        if (input.files && input.files[0]) {
                            var reader = new FileReader();

                            reader.onload = function (e) {
                                $('#noPic').attr('src', e.target.result);
                            }

                            reader.readAsDataURL(input.files[0]);
                        }
                    }
                </script>
            </div>
            </td>
        </tr>
    </table>
</form>

和用PHP处理的代码：

<?php

    // Pic Var
        $nmFoto = $_FILES['picPTK']['name'];
        $tyFoto = $_FILES['picPTK']['type'];
        $szFoto = $_FILES['picPTK']['size'];
        $erFile = $_FILES['picPTK']['error'];
        $temp = $_FILES['picPTK']['tmp_name'];
        $tyFoto = $_FILES['picPTK']['type'];
        $dir = '../../images/ptk/';
        $ftExt = array('jpeg', 'jpg', 'png');
        $ftTemp = explode('.' , $nmFoto);
        $ext = end($ftTemp); 
?>

要检查我使用此代码段的图片数据

echo $tyFoto;
    echo $temp;
    echo $szFoto;
    var_dump($erFile);

成功后显示

Pic Name : 3dpencil10.jpg
Pic Type : image/jpeg
Pic Temp : C:\xampp\tmp\phpFBAD.tmp
Pic Size : 101632
Error file (var_dump) : int(0) << error shows (0) (i think it means (false)

显示失败的图片

Pic Name : IMG_0668.JPG << It gets the name, but not the type
Pic Type : 
Pic Temp : 
Pic Size : 0
Error file (var_dump) : int(1) << error shows (1) (i think it means (true)

这是我的整个上传脚本：

我知道POST文件的名称是不同的，例如我在上面使用的名称。

我试图将其更改为STRTOLOWER，并在大写中添加了几种类型，但它仍然无法正常工作..

寻找

if((($tyFoto=='image/jpeg') 
                        || ($tyFoto=='image/jpg') 
                        || ($tyFoto=='image/pjpg') 
                        || ($tyFoto=='image/x-png') 
                        || ($tyFoto=='image/png')) 
                        && ($szFoto < 2000000) 
                        && in_array($ext, $ftExt))
                        {

我用它来阻止用户上传文件但图片，并且我不断收到错误，因为假设图片的类型未知（不是图片类型）.. 所以我认为这是问题。

解决

最后一次更改我已经完成了上传脚本解决了我的问题，谢谢大家：

我已经对我的php.ini

进行了最后的更改

上传文件的最大允许大小。 ; http://php.net/upload-max-filesize 的upload_max_filesize = 10M

PHP将接受的POST数据的最大大小。 ;其值可能为0以禁用限制。如果POST数据读取则忽略它 ;通过enable_post_data_reading禁用。 ; http://php.net/post-max-size 的post_max_size = 10M

Answer 1

除非你有其他代码

$ftExt = array('jpeg', 'jpg', 'png');

请记住，如果没有strtolower文本......

.JPG与.jpg

不同

您可以使用不同的方式，例如1：

$ftExt = array('jpeg', 'jpg', 'png', 'JPG');

或strtolower文件名

Answer 2

也许是因为文件大小？

您可以尝试在php.ini

中设置以下值

upload_max_filesize = 10M
post_max_size = 10M

Answer 3

您是否可以发送无法上传的图片的特征（文件大小，文件名）？

正如其他人指出的那样，对扩展程序的验证可能是您问题的原因，您可以轻松解决这个问题：

in_array(strtolower($ext), $ftExt)

但是文件大小也可能是一个问题，就像在大多数系统上一样（通常是共享主机方案），最大文件大小限制在2M（这就是为什么你经常看到网站限制你可以上传的图像的大小）。

如果我记得很清楚，$ _FILES数组包含一个错误索引，所以尝试做一个

print_r($_FILES)

并向我们提供无法上传的图片的结果。

图片上传PHP仅适用于某些图片

解决
