当我不想上传头像并保留默认值“avatar1.jpg”时,它会不断给我同样的错误消息。 "文件类型无效!"可能有什么不对? 当我上传头像时,它可以正常工作。
此代码是函数,它位于functions.php
中public function uploadAvatar(){
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["avatar"]["name"]);
$extension = end($temp);
if ((($_FILES["avatar"]["type"] == "image/gif")
|| ($_FILES["avatar"]["type"] == "image/jpeg")
|| ($_FILES["avatar"]["type"] == "image/jpg")
|| ($_FILES["avatar"]["type"] == "image/pjpeg")
|| ($_FILES["avatar"]["type"] == "image/x-png")
|| ($_FILES["avatar"]["type"] == "image/png"))
&& ($_FILES["avatar"]["size"] < 1000000)
&& in_array($extension, $allowedExts)) {
if ($_FILES["avatar"]["error"] > 0) {
redirect('register.php', $_FILES["avatar"]["error"], 'error');
} else {
if (file_exists("images/avatars/" . $_FILES["avatar"]["name"])) {
redirect('register.php', 'File already exists', 'error');
} else {
move_uploaded_file($_FILES["avatar"]["tmp_name"],
"images/avatars/" . $_FILES["avatar"]["name"]);
return true;
}
}
}
else {
redirect('register.php', 'Invalid File Type!', 'error');
}
}
此代码正在获取功能,&#34; if($ user-&gt; uploadAvatar()){...}&#34;如果没有上传任何内容,则设置默认图片。
if(isset($_POST['register-input'])){
//Create Data Array
$data = array();
$data['name'] = $_POST['name'];
$data['email'] = $_POST['email'];
$data['username'] = $_POST['username'];
$data['password'] = md5($_POST['password']);
$data['password2'] = md5($_POST['password2']);
$data['about'] = $_POST['about'];
$data['last_activity'] = date("Y-m-d H:i:s");
//Required Fields
$field_array = array('name','email','username','password','password2');
if($validate->isRequired($field_array)){
if($validate->isValidEmail($data['email'])){
if($validate->passwordsMatch($data['password'],$data['password2'])){
//Upload Avatar Image
if($user->uploadAvatar()){
$data['avatar'] = $_FILES["avatar"]["name"];
} else{
$data['avatar'] = 'avatar1.jpg';
}
//Register User
if($user->register($data)){
redirect('index.php', 'You are registered and can now log in', 'success');
} else {
redirect('index.php', 'Something went wrong with registration', 'error');
}
} else {
redirect('register.php', 'Your passwords did not match', 'error');
}
} else {
redirect('register.php', 'Please use a valid email address', 'error');
}
} else {
redirect('register.php', 'Please fill in all required fields', 'error');
}
}

如果您没有上传avatar
文件,那么与检查$_FILES["avatar"]["type"]
时相比,您将始终收到错误的null == "image/gif" || null == "image/jpeg"...
。
首先通过执行if (!empty($_FILES['avatar']))
旁注您可以更改此代码:
($_FILES["avatar"]["type"] == "image/gif")
|| ($_FILES["avatar"]["type"] == "image/jpeg")
|| ($_FILES["avatar"]["type"] == "image/jpg")
|| ($_FILES["avatar"]["type"] == "image/pjpeg")
|| ($_FILES["avatar"]["type"] == "image/x-png")
|| ($_FILES["avatar"]["type"] == "image/png")
到
in_array($FILES['avatar']['type'], ["image/gif", "image/jpeg", "image/pjpeg", "image/x-png", "image/png"])

你可以使用:
if($user->uploadAvatar()){
$data['avatar'] = $_FILES["avatar"]["name"];
} else{
$file = 'avatar1.jpg';
// Open the file to get existing content
$data = file_get_contents($file);
// New file
$new = 'new_name.jpg';
// Write the contents back to a new file
file_put_contents($new, $data);
}

在uploadAvatar
的顶部,您需要在开始工作之前检查是否有要处理的文件。使用这些行
if(empty($_FILES['avatar']) ||
!file_exists($_FILES['avatar']['tmp_name']) ||
!is_uploaded_file($_FILES['avatar']['tmp_name'])
) return false;
