在我的网站上上传照片时遇到问题。
我在$fileName = basename($_FILES["file"]["name"]);
行收到最后一条错误消息(“请选择要上传的文件”),并且没有插入到数据库或在服务器上上传。
我想知道插入是否有问题,因为我要插入文件名,然后通过执行'images /'和文件名来插入url。所有图像都将上传到图像目录中,因此我想确保URL始终始终在其前面。'
我不确定这里还有什么问题,但也许我遗漏了一些东西
这是表格和php脚本:
<form action="uploadImage.php" method="post" enctype="multipart/form-data">
<div class="form-group">
<label for="formControl">Upload Image</label>
<input type="file" class="form-control-file" id="formControl">
<input type="submit" name="fileUpload">
</div>
</form>
$statusMsg = '';
// File upload path
$targetDir = "images/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
// Allow certain file formats
$allowTypes = array('jpg','png','jpeg','gif','pdf');
if(in_array($fileType, $allowTypes)){
// Upload file to server
if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){
// Insert image file name into database
$insert = $mysqlConn->query("INSERT into images (image_name, url) VALUES ('".$fileName."', 'images/".$fileName."'");
if($insert){
$statusMsg = "The file ".$fileName. " has been uploaded successfully.";
}else{
$statusMsg = "File upload failed, please try again.";
}
}else{
$statusMsg = "Sorry, there was an error uploading your file.";
}
}else{
$statusMsg = 'Sorry, only JPG, JPEG, PNG, GIF, & PDF files are allowed to upload.';
}
}else{
$statusMsg = 'Please select a file to upload.';
}
// Display status message
echo $statusMsg;
答案 0 :(得分:1)
根据您的验证,您应该像这样修改html标记:
<input type="file" name="file" class="form-control-file" id="formControl">
<input type="submit" name="submit">
或将您的验证条件更改为
if (isset($_POST["fileUpload"]) && !empty($_FILES["file"]["name"])) {
...
}
无论如何,文件输入元素需要name="file"
。
