Form＆Upload on一个提交

Question

我一直在努力解决这个问题。

我有一个捕获数据和空表单字段验证的表单，如果任何字段为空，就会阻止提交表单。

此外，我有一个输入，允许用户上传图像。问题是用户可以上传图片而不需要在表格中输入任何数据。由于图像与表单链接，因此必须在单个提交中书写，而不是独立写入。

我只发布了一小段代码样本，因为我认为问题是表单和输入不是php？

<form enctype="multipart/form-data" method="POST" action="textandimages.php"> 

<div><input id="name" class="insetcard" name="name" type="text" placeholder="Name" value="<?PHP print $name ; ?>"/> 
<p class="error"><?php echo $nameErr;?></p></div> 

<input type="file" name="upload" /> 

<input name="Submit" type="submit" class="submitbutton" value="submit">

测试你的textandimages.php两个值：

if(isset($_POST['name'],$_POST['upload']) && !empty($_POST['name']) && !empty($_POST['upload'])){ 
// do something 
} else { 
//error, something is missing... 
}
