这是我的 HTML 代码：
form.php
表单.php
<html>
<body>
<form action="uploadFile.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>

date_default_timezone_set('Philippines/Manila');

$UPLOADDIR = "images/";
// if the form has been submitted then save and display the image(s)
if(isset($_POST['Submit'])){
// loop through the uploaded files
foreach ($_FILES as $key => $value){
$image_tmp = $value['tmp_name'];
$image_type=$value['type'];
$image = $value['name'];
$image_file = "{$UPLOADDIR}{$image}";
//check if there's existing file name
if ($image != 0){
echo 'File Already Exists!';
}
else {
// move the file to the permanent location
if(move_uploaded_file($image_tmp,$image_file)){
// this is where the displaying part goes

To do that you need to upload the image using some kind of ajax upload. if you don't know what is that, please read here http://en.wikipedia.org/wiki/Ajax_%28programming%29. You can find some free solutions and examples online. Here I found a stack overflow question that might help you with links to such a solutions
为此，您需要使用某种 ajax 上传来上传图像。如果您不知道那是什么，请在此处阅读http://en.wikipedia.org/wiki/Ajax_%28programming%29。您可以在网上找到一些免费的解决方案和示例。在这里，我发现了一个堆栈溢出问题，它可能会帮助您找到此类解决方案的链接

Add an iframeafter your form:
iframe在表单后面添加：
<iframe name="resultFrame" width="500" height="300"></iframe>
<iframe name="resultFrame" width="500" height="300"></iframe>
And add the target="resultFrame"attribute in your form like this:
并target="resultFrame"在您的表单中添加属性，如下所示：
<html>
<body>
<form action="uploadFile.php" method="post"
enctype="multipart/form-data" target="resultFrame">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>
<iframe name="resultFrame" width="500" height="300"></iframe>
</body>
</html>

Upload your image in a folder which contains your php/html file, and in img tag write the img name:
将您的图片上传到包含您的 php/html 文件的文件夹中，并在 img 标签中写入 img 名称：
<img src="<?php echo $img;?>" width="400" height="600"/>

/* i put image so that it has default
<img id="blah" src="images/male.png" alt="your image" style="width:250px;height:200px;" />
/*put accept and its format so that you can only choose the image only
<input type='file' name="image" onchange="readURL(this);" accept="image/gif,image/png,image/jpg,image/jpeg" />
/*changing the url of an image you can do it in jquery
function readURL(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#blah')
.attr('src', e.target.result)
/*set the width and height of an image
.width(250)
.height(200);
};
reader.readAsDataURL(input.files[0]);
}
}
after that do your upload code
之后做你的上传代码
