PHP多次上传保留文件名

php file-upload

PHP多次上传保留文件名,php,file-upload,Php,File Upload,我有一个脚本，我用来上传多个图像，但这个脚本每次重命名我的图像，我不想要它。如何保留原始图像名称？ 这是我的代码： <?php if (isset($_POST['submit'])) { $j = 0; // Variable for indexing uploaded image. $target_path = "../images/gallery/"; // Declaring Path for uploaded images. for ($i

我有一个脚本，我用来上传多个图像，但这个脚本每次重命名我的图像，我不想要它。如何保留原始图像名称？ 这是我的代码：

<?php
if (isset($_POST['submit'])) {
    $j = 0;     // Variable for indexing uploaded image.
    $target_path = "../images/gallery/";     // Declaring Path for uploaded images.
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {
        // Loop to get individual element from the array
        $validextensions = array("jpeg", "jpg", "png");      // Extensions which are allowed.
        $ext = explode('.', basename($_FILES['file']['name'][$i]));   // Explode file name from dot(.)
        $file_extension = end($ext); // Store extensions in the variable.
        $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];     // Set the target path with a new name of image.
        $j = $j + 1;      // Increment the number of uploaded images according to the files in array.
        if (($_FILES["file"]["size"][$i] < 10000000) && in_array($file_extension, $validextensions)) {     // Approx. 100kb files can be uploaded.
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {
                // If file moved to uploads folder.
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
            } else {     //  If File Was Not Moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {     //   If File Size And File Type Was Incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
}
?>



在这里，您正在使用
md5（uniqid（））
更改文件名，而不是像
$\u FILES['file']['name'][$i]
这样的文件名。我已经编辑了您的代码。这应该行得通


<?php
if (isset($_POST['submit'])) {
$j = 0;     // Variable for indexing uploaded image.
$target_path = "../images/gallery/";     // Declaring Path for uploaded images.
for ($i = 0; $i < count($_FILES['file']['name']); $i++) {
    // Loop to get individual element from the array
    $validextensions = array("jpeg", "jpg", "png");      // Extensions which are allowed.
    $ext = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);

    $target_path .= $_FILES['file']['name'];
    $j = $j + 1;      // Increment the number of uploaded images according to the files in array.
    if (($_FILES["file"]["size"][$i] < 10000000) && in_array($ext, $validextensions)) {     // Approx. 100kb files can be uploaded.
        if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {
            // If file moved to uploads folder.
            echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
        } else {     //  If File Was Not Moved.
            echo $j. ').<span id="error">please try again!.</span><br/><br/>';
        }
    } else {     //   If File Size And File Type Was Incorrect.
        echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
    }
}
}
?>



您必须删除此行


$target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];


只需添加
$\u文件['file']['name'][$i]

定义

uniqid（）-uniqid（）函数根据微时间（以微秒为单位的当前时间）生成唯一的ID

您可以在
php.ini
文件上更改
max\u file\u上载的值。默认情况下，它是
20
。你想增加多少就增加多少

此外，您还可以尝试此代码

$target\u path=$target\u path。md5（uniqid（）。"." . $分机[计数（$ext）-1]；//使用图像的新名称设置目标路径？？？？？？我必须换那一行吗？我怎么做？谢谢，请检查我的答案。嗨，谢谢你的回答。我尝试了您的解决方案，但我得到了以下结果：原始文件名：image-1.jpg，image-2.jpg，image-3.jpg更改结果：image-1.jpg.jpg.jpgimage-2.jpg.jpg，image-1.jpg.jpgimage-2.jpg.jpgimage-3.jpg我只需要保留每个文件名：）好的，我得到了您需要删除“$ext[count（$ext）-1]”的问题这部分代码将得到您想要的输出。那么，它应该是这样的吗$目标路径=$target\u路径$_文件['file']['name'][$i]；我得到了这个错误：“警告：pathinfo（）希望参数1是字符串，数组在第8行1的/web/htdocs/www.xxx.com/xxx/upload/upload.php中给出）。***无效的文件大小或类型***更改此行：$ext=pathinfo（$\u FILES['file']['name']，pathinfo扩展名）；改为：$ext=pathinfo（$\u FILES['file'['name'][$I]，pathinfo扩展名）；没关系，但我不想重命名图像名称，如果您希望图像的名称相同，它会使用md5重命名图像。为什么不保留它们的原样（$_FILES['file']['name']）；因为我在网上找到了这段代码，我不知道如何更改它。你能帮我吗？谢谢：）对不起，但你能更好地解释一下吗？$target\u path=$target\u path.md5（uniqid（））。“..$ext[count（$ext）-1]；只需添加$\u文件['file']['name'][$I]
