我的表单中有文件上传和文本输入字段，我想要在同一页面上显示文件上传的错误消息，如果有错误不要转到下一页...如果文件上传有错误还将文本字段的值返回到同一页面......我该怎么做？ 

<form action="send.php" method="post"  enctype="multipart/form-data">
<input type="hidden" name="submited" value="true" /><br>
<label for="file">Choose Photo:</label>
<input type="file" name="file" required><br>
First Name:<input type="text" name="fname" required><br>
Last Name:<input type="text" name="lname" required><br>
Choose Username:<input type="text" name="username" required><br>
Age:<input type="text" name="age" required><br>
<input type="submit" value="Submit" name="submit" >

</form>
</body>
</html>

这是文件上传的 php 代码....我将把数据从<input type="text">数据库中插入，我现在没有代码...

    <?php
ini_set( "display_errors", 0);
if(isset($_REQUEST['submited'])) {

// your save code goes here

$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 2097152)
&& in_array($extension, $allowedExts))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
}
else
{
echo "";

if (file_exists("images/" . $_FILES["file"]["name"]))
{
echo "<font color='red'><b>We are sorry, the file you trying to upload already exists.</b></font>";
  }

else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"images/" . $_FILES["file"]["name"]);
echo "<font color='green'><b> Success! Your photo has been uploaded.</b></font>";
}
}
}
else
{
echo "<font color='red'><b>We are sorry, the file you trying to upload is not an image or it exceeds 2MB in size.</b></font><br><font color='blue'><i>Only images under size of 2MB are allowed</i></font>.";
}
}
?>

如果发生错误，只需让您的 PHP 重新生成填写了字段的表单（即 sst value 属性）。

嘿，

要将其保持在同一页面上，您可以删除该操作

发送.php

然后将此处显示的 html 和 php 代码添加到同一文件中。执行该文件时，它将保留在同一页面上。
