我目前在使用class.upload.php上传图片时插入字幕时遇到问题。
图像重命名效果很好，但所有图像都有相同的标题，尽管我为每个图像设置了单独的文本框。
代码：
<form action="" enctype="multipart/form-data" id="form" method="post" name="form" role="form">
<table>
<tr>
<td><input class="form-control" id="customFieldValue2" name="photo_title[]" type="text"></td>
<td><input class="form-control" id="customFieldName2" name="image_field[]" type="file"></td>
</tr>
<tr>
<td><input class="form-control" id="customFieldValue2" name="photo_title[]" type="text"></td>
<td><input class="form-control" id="customFieldName2" name="image_field[]" type="file"></td>
</tr>
</table>
</form>
处理器：
$files = array();
foreach ($_FILES['image_field'] as $k => $l) {
foreach ($l as $i => $v) {
if (!array_key_exists($i, $files))
$files[$i] = array();
$files[$i][$k] = $v;
}
}
$hitung=0;
foreach ($files as $file)
{
$handle = new Upload($file);
if ($handle->uploaded)
{
$hitung++;
$newname = $t_timestamp."_".$hitung;
$handle->file_new_name_body = $newname;
$handle->Process("../uploaded/");
if ($handle->processed)
{
$filename=$newname.".jpg";
$query ="INSERT INTO tbl_report_photos SET
photo_title='".$filename."',
photo_link='".$filename."',
photo_unique='".$aid."'";
if ($sql = mysqli_query($con,$query))
{
echo "<script>alert('Report Updated');window.location.href='index.php';</script>";
}
}
else
{
echo 'Error: ' . $handle->error;
}
}
else
{
echo 'Error: ' . $handle->error;
}
unset($handle);
}
我编辑了代码。它有一个较少的循环
答案 0 :(得分：0)
你拥有相同标题的原因在于它自己的循环，它不是在排列变量，而是覆盖自身。使它成为一个数组，然后写相应的键：
$taitel[$i] = $_POST['photo_title'][$i];
你有很多循环，很难建议把它放在你的剧本中。
编辑：由于您在设置此问题时遇到问题，我将进行演示。我可能会尝试一些事情。一，我将创建一个文件观察者和两个，创建一个上传类的扩展类。那个看起来有点尴尬：
<强> UploadObserver.php
/*
** @description This will take over for a couple of pieces of your script
*/
class UploadObserver
{
private $Upload;
/*
** @description Pass your database. I like PDO and know it better so I am using that connection
** You would have to change this to accept your MySQLi connection
*/
public function __construct(\PDO $con)
{
$this->con = $con;
}
/*
** @description Create a new instance of a version of the Upload class
*/
public function upload($file)
{
# Create a new instance of our extended class
$this->Upload = new \PowerUpload($file);
# Return it for use
return $this->Upload;
}
/*
** @description This is the class that will process the files array
*/
public function getFiles($key = 'image_field')
{
$files = array();
foreach ($_FILES[$key] as $k => $l) {
foreach ($l as $i => $v) {
if (!array_key_exists($i, $files))
$files[$i] = array();
$files[$i][$k] = $v;
}
}
# Send back formatted array
return $files;
}
/*
** @description Checks to see if the files array has files
*/
public function filesSet($key = 'image_field')
{
return (!empty($_FILES[$key]));
}
/*
** @description This will write the row to your database
*/
public function saveToDb($settings)
{
# Make sure to prepare and bind your values just in case
$sql ="INSERT INTO tbl_report_photos SET
photo_title = ?,
photo_link = ?,
photo_unique = ?";
$query = $this->con->prepare($sql);
$query->execute($settings);
}
/*
** @description You could store this in a View class, but for sake of ease I included it here
*/
public function getSuccess()
{
ob_start();
?>
<script>
alert('Report Updated');
window.location.href = 'index.php';
</script>
<?php
$data = ob_get_contents();
ob_end_clean();
return $data;
}
}
<强> upload.php的
根据您在示例中演示的内容，这只是猜测这个类的外观。
class Upload
{
public $uploaded,
$file_new_name_body,
$processed,
$error;
protected $filename,
$fileArray;
public function __construct($fileArray)
{
$this->fileArray = $fileArray;
}
public function process($path)
{
if(!is_dir($path))
mkdir($path,0755,true);
if(empty($this->file_new_name_body))
$this->file_new_name_body = $this->fileArray['name'];
$this->error = $this->fileArray['error'];
$this->processed = move_uploaded_file($this->fileArray['tmp_name'],str_replace('//','/',$path.'/'.$this->file_new_name_body));
if(!$this->processed)
throw new \Exception("File was unable to upload.");
}
}
<强> PowerUpload.php
/*
** @description If you can, I would extend the Upload class and save some more readable methods to it
*/
class PowerUpload extends Upload
{
public function setNewFile($fileArray)
{
$this->fileArray = $fileArray;
return $this;
}
public function setFileName($name)
{
$this->file_new_name_body = $name;
return $this;
}
public function checkHasUploaded()
{
$files = (!empty($this->fileArray));
if(!$files)
throw new \Exception("File array can not be empty.");
return $files;
}
public function hasProcessed()
{
return $this->processed;
}
public function processUpload($path)
{
$this->process($path);
}
public function getError()
{
return $this->error;
}
}
基于更改的修改脚本：请注意，表单输入名称具有实际键值，因此您可以更轻松地将文件与名称匹配。
# Create the upload observer, $con is your database connection
$Uploader = new UploadObserver($con);
# If there are files uploading
if($Uploader->filesSet()) {
# Create a loop from the new array
# Keep the $key value to match it up with the files value
foreach($Uploader->getFiles() as $key => $file) {
# Use a try because the uploader submits exceptions on failures
try {
# Set the name
$newname = $t_timestamp."_".$key;
# Tag on the extension
$filename = $newname.".jpg";
# Create the upload instance
$handle = $Uploader->upload($file);
# This will throw exception if failed
$handle->checkHasUploaded();
# Assign the file name and upload the file to folder
$handle->setFileName($newname)->processUpload(realpath(__DIR__.'/..').'/uploaded/');
# Save the file info to your database using the connection passed originally
# You should throw exception here on database fail, PDO does it automatically so it's caught
$Uploader->saveToDb(array($_POST['photo_title'][$key],$filename,$aid));
# Create javascript view
echo $Uploader->getSuccess();
}
# Catch error(s) from the non-db classes
catch(\Exception $e) {
echo 'Error: '.$e->getMessage();
}
# Catch error(s) from the db classes
catch(\PDOException $e) {
echo 'Error: '.$e->getMessage();
}
}
}
