Question

我正在尝试在输入按钮下方显示上传文件的名称。一旦文件被选中并添加到服务器“file_name.ext上传”，默认文本应该说“No File Uploaded”。

此处是我的代码：

<label for='upload' class='upload-button'></label><input type='file' name="fileAttach" class='upload-button' id='upload'/><br>Upload Site List
<?php
if (isset($_FILES['fileAttach']['name'])) {
    echo "File is attached.";
}
?>

此代码位于表单页面上，使用带有enctype multipart / form-data的POST。

我的知识低于入门级，所以如果这是一个非常简单的问题，我很抱歉。到目前为止我找到的所有信息都无济于事。

Answer 1

<label for='upload' class='upload-button'></label><input type='file' name="fileAttach" class='upload-button' id='upload'/><br>Upload Site List
    <?php
    if(isset($_FILES['fileAttach']['name'])) {
        echo $_FILES['fileAttach']['name']." was uploaded";
    }else{
        echo "No File Uploaded";
    }
    ?>

Answer 2

表单必须提交给php以回应声明。

<form enctype="multipart/form-data" action="" method="POST">
<input type='file' name="fileAttach" class='upload-button' id='upload'/>
<input type="submit">
</form>

<br>Upload Site List<br>
<?php
    if(isset($_FILES['fileAttach']['name'])) {
        echo $_FILES['fileAttach']['name'] . " was uploaded";
    } else {
        echo "No File Uploaded";
    }
?>
