上传图像PHP SQL
上传图像PHP SQL
提问于 2018-08-19 03:46:13
我的上传脚本有问题，希望有人能帮助我。
<?php
if(isset($_POST['submit'])){
// Include the database configuration file
include_once 'dbconfig.php';
// File upload configuration
$targetDir = "uploads/";
$allowTypes = array('jpg','png','jpeg','gif');
$statusMsg = $errorMsg = $insertValuesSQL = $errorUpload = $errorUploadType = '';
if(!empty(array_filter($_FILES['files']['name']))){
foreach($_FILES['files']['name'] as $key=>$val){
// File upload path
$fileName = basename($_FILES['files']['name'][$key]);
$targetFilePath = $targetDir . $fileName;
// Check whether file type is valid
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
if(in_array($fileType, $allowTypes)){
// Upload file to server
if(move_uploaded_file($_FILES["files"]["tmp_name"][$key], $targetFilePath)){
// Image db insert sql
$insertValuesSQL .= "('".$fileName."', NOW()),";
}else{
$errorUpload .= $_FILES['files']['name'][$key].', ';
}
}else{
$errorUploadType .= $_FILES['files']['name'][$key].', ';
}
}
if(!empty($insertValuesSQL)){
$insertValuesSQL = trim($insertValuesSQL,',');
// Insert image file name into database
$insert = $db->query("INSERT INTO images (file_name, uploaded_on) VALUES $insertValuesSQL");
if($insert){
$errorUpload = !empty($errorUpload)?'Upload Error: '.$errorUpload:'';
$errorUploadType = !empty($errorUploadType)?'File Type Error: '.$errorUploadType:'';
$errorMsg = !empty($errorUpload)?'<br/>'.$errorUpload.'<br/>'.$errorUploadType:'<br/>'.$errorUploadType;
$statusMsg = "Files are uploaded successfully.".$errorMsg;
}else{
$statusMsg = "Sorry, there was an error uploading your file.";
}
}
}else{
$statusMsg = 'Please select a file to upload.';
}
// Display status message
echo $statusMsg;
}
?>
<html>
<form action="" method="post" enctype="multipart/form-data">
Select Image Files to Upload:
<input type="file" name="files[]" multiple>
<input class="upload-btn" type="submit" name="submit" value="UPLOAD">
</form>
</html>如果我单击submit按钮，但没有选择任何图像，则代码将在屏幕上打印Please select a file to upload.。
如果我用选中的图像单击submit按钮，代码不会显示任何内容，也不会上传任何图像。
出什么问题了？

似乎未正确访问文件数组。试试这段代码
if(!empty($_FILES)){
foreach($_FILES as $key=>$val){
// File upload path
$fileName = basename($val['name']);
$targetFilePath = $targetDir . $fileName;
// Check whether file type is valid
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
if(in_array($fileType, $allowTypes)){
// Upload file to server
if(move_uploaded_file($val["tmp_name"], $targetFilePath)){
// Image db insert sql
$insertValuesSQL .= "('".$fileName."', NOW()),";
}else{
$errorUpload .= $val['name'].', ';
}
}else{
$errorUploadType .= $val['name'].', ';
}
}
