是一个基于 PHP 的内容管理系统(CMS),它提供了丰富的功能来管理网站内容,包括文件上传功能。前台上传文件通常指的是用户通过网站的界面上传文件到服务器。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>File Upload</title>
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload File" name="submit">
</form>
</body>
</html>
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// 检查是否是真实的图片
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
} else {
echo "File is not an image.";
}
}
?>
getimagesize
检查图片,避免上传可执行文件。通过以上步骤和代码示例,你应该能够在 phpcms
前台实现文件上传功能,并解决常见的上传问题。
