上传默认图片，如果用户没有上传任何 [英] Upload default image if user didn't upload any

问题描述

我有一段代码upload.php

I have a piece of code from upload.php

$uploaddir = '../photo/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
if(move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))
{
    //...
}

如何添加一个函数，如果用户没有上传图片，那么默认图片上传？

How can I add a function that if user didn't upload an image, then a default image is uploaded?

推荐答案

你也可以使用这个：
（当然在echo下面） b

you can use this also: (of course under echo "" in case of php)

// Replace source with other image in case user didn't upload any photo
$('img').error(function(){
        $(this).attr('src', 'missing.png');
});

// Or, hide the 'broken image' 
$("img").error(function(){
        $(this).hide();
});
