Question

我正在尝试上传图片。我创建了一个函数，用一个支持的文件类型替换不受支持的文件类型的扩展。（例如“honeydew.docx to honeydew.jpg”）

输出将是“'Honeydew.docx已成功上传，如果成功则重命名为honeydew.jpg”。我可以获得“已成功上传”部分，但无法显示“已重命名”部分消息。为什么会这样？

表格中的来电者.php

<?php 
use foundationphp\UploadFile;

$max = 50 * 1024;
$result = array();
if (isset($_POST['upload'])) {
require_once 'src/foundationphp/UploadFile.php';
$destination = __DIR__ . '/uploaded/';
try {
    $upload = new UploadFile($destination);
    $upload->setMaxSize($max);
    $upload->allowAllTypes();
    $upload->upload();
    $result = $upload->getMessages();
} catch (Exception $e) {
    $result[] = $e->getMessage();
}
}
?>

UploadFile.php中的函数处理程序

/*Function responsible for the output message*/
protected $newName;
protected function moveFile($file) 
{
    $filename = isset($this->newName) ? $this->newName : $file['name'];
    $success = move_uploaded_file($file['tmp_name'], $this->destination . $filename);
    if ($success) {
        $result = $file['name'] . ' was uploaded successfully';
        if (!is_null($this->newName)) {
            $result .= ', and was renamed ' . $this->newName;
        }
        $result .= '.';
        $this->messages[] = $result;
    } else {
        $this->messages[] = 'Could not upload ' . $file['name'];
    }
}

/*Function to allow docs with all types of extensions to be displayed*/
protected $typeCheckingOn = true;
    public function allowAllTypes($suffix = null)
{
    $this->typeCheckingOn = false;
    if (!is_null($suffix)) {
        if (strpos($suffix, '.') === 0 || $suffix == '') {
            $this->suffix = $suffix;
        } else {
            $this->suffix = ".$suffix";
        }
    }
}

Answer 1

尝试更改

if (!is_null($this->newName)) {

用

if (isset($this->newName)) {

正如您在上面的代码中使用这种方法一样。

虽然，我们只能预测错误的位置。请发布整个 UploadFile.php 课程。
