Question

我正在尝试上传包含2个文件的表单，其中一个是.dae个对象，另一个是image。表单（它在JS bootbox dialog内）：

message:  '<form name="uploadForm" action="Control/upload.php" method="post" enctype="multipart/form-data"> '
                + '     Nome do objeto:<br />'
                + '     <input name="objectname" type="text"><br />'
                + '     <input type="hidden" name="MAX_FILE_SIZE" value="10000000">'
                + '     Objeto 3D(Formato <b>.dae</b>):<br />'
                + '     <input name="userfile[]" type="file" /><br />'
                + '     Imagem 2D do objeto(Formato <b>.png</b> ou <b>.jpg</b>) (<i>Opcional</i>):'
                + '     <input name="userfile[]" type="file" /><br />'
                + '     Comentário:<br />'
                + '     <textarea name="comment" rows="5" cols="75"></textarea>'
                + '</form>',

在表单中，有两个上传文件，“Objeto 3D”（3d对象，.dae）和“Imagem 2D do Objeto”（对象的图像2d，.jpg, .png）有必要上传仅对象文件，图片是可选的，因为如果没有上传，则数据库中有标准文件。

我试图让它工作创建一个布尔$ imageUploaded，它在getFileInputs方法中设置，但不知何故，它不能正常工作..

如果我上传 a .dae和图片，则效果很好
如果我上传错误的文件扩展名，它可以正常工作（2个错误或1个at 一次）
但是，如果我只上传一个.dae文件，它就是我的错误图片文件扩展名错误...

这是我的代码（它在其他脚本上运行）（没有数据库代码，这里不需要）

<?php 

    class UploadObject{
        //Control vars

            $alertMessage = "<script >bootbox.alert({ message: '";

            $alertMessage = $alertMessage . $message;

            $alertMessage = $alertMessage . "', callback: function(){location.href='../index.php';} })</script>";

            echo $alertMessage;


        }

        //Getters and Setters
        ...
        ?>

无论如何，我是PHP新手，自己编写这段代码学习了一下，但是虽然这个问题无法工作......有人能告诉我哪里是我的错误吗？

Answer 1

您可以先使用 print_r（$ _ FILES）; 调试一下。比较单独上传.dae文件时获得的内容，以及上传.dae文件和图像时获得的内容。然后添加条件逻辑以使函数uploadTheFiles（）跳过尝试上传图像（如果没有设置）。

PHP使用Optionals上传多个文件（至少需要2个文件中的1个）
