Question

为了上帝的缘故，有人可以帮我制作下面的剧本来上传多张图片（5）。我被困在这几天没有运气。我不知道如何上传五张图片。 Pleeeease帮助我。我尝试放置五个输入文件字段，并给它们命名为name="file[]"，但这似乎不起作用。当我上传照片时，我发现错误说即使有文件也请选择照片。

<?php

function uploadFile ($file_field = null,  $check_image = false, $random_name = false) {

//Config Section    
//Set file upload path
$path = 'Productpic/'; //with trailing slash
//Set max file size in bytes
$max_size = 2097152;
//Set default file extension whitelist
$whitelist_ext = array('jpg','png','gif', 'JPG');
//Set default file type whitelist
$whitelist_type = array('image/jpeg', 'image/png','image/gif','image/JPG');

//The Validation
// Create an array to hold any output
$out = array('error'=>null);

if (!$file_field) {
$out['error'][] = "Please specify a valid form field name";           
}

if (!$path) {
$out['error'][] = "Please specify a valid upload path";               
}

if (count($out['error'])>0) {
return $out;
}

//Make sure that there is a file
if((!empty($_FILES[$file_field])) && ($_FILES[$file_field]['error'] == 0)) {

// Get filename
$file_info = pathinfo($_FILES[$file_field]['name']);
$name = $file_info['filename'];
$ext = $file_info['extension'];

//Check file has the right extension           
if (!in_array($ext, $whitelist_ext)) {
  $out['error'][] = "<span class='isa_error2'>Invalid file Extension</span>";
}

//Check that the file is of the right type
if (!in_array($_FILES[$file_field]["type"], $whitelist_type)) {
  $out['error'][] = "<span class='isa_error2'>Invalid file Type</span>";
}

//Check that the file is not too big
if ($_FILES[$file_field]["size"] > $max_size) {
    $out['error'][] = "<span class='isa_error2'>File is too big</span>";
}

//If $check image is set as true
if ($check_image) {
  if (!getimagesize($_FILES[$file_field]['tmp_name'])) {
    $out['error'][] = "<span class='isa_error2'>The file you trying to upload is not an Image, we only accept Images</span>";
}
}

//Create full filename including path
if ($random_name) {

// Generate random filename
  $tmp = str_replace(array('.',' '), array('',''), microtime());

if (!$tmp || $tmp == '') {
$out['error'][] = "File must have a name";
}     
$newname = $tmp.'.'.$ext;                                
} else {
    $newname = $name.'.'.$ext;
}

//Check if file already exists on server
if (file_exists($path.$newname)) {
  $out['error'][] = "<span class='isa_error2'>The image you trying to upload already exists, please upload only once</span>";
}

if (count($out['error'])>0) {
  //The file has not correctly validated
  return $out;
} 

if (move_uploaded_file($_FILES[$file_field]['tmp_name'], $path.$newname)) {
  //Success

  $out['filepath'] = $path;
  $out['filename'] = $newname;
  return $out;
} else {
  $out['error'][] = "Server Error!";
}

} else {
$out['error'][] = "<span class='isa_error2'>Please select a photo</span>";
return $out;
}      
}
?>

$file = uploadFile('file', true, false);
if (!is_array($file['error'])) {
$message = '';
$sub=1;
$message = "<span class='isa_success'>File uploaded successfully</span>";

echo $message;

Answer 1

其他人可能会阅读此内容，因此我将解释如何将输入的名称设置为name="file[]"。

这意味着您正在创建包含所选文件名的数组。为了以后上传它们或将信息保存到数据库，你必须循环通过数组：

foreach(file[] as $key){}

在我看来，另一个解决方案，更麻烦的代码，是给每个文件输入一个不同的名称，就像问问题的人解决了他的问题。

如果我错了，请纠正我。

Answer 2

嗯我解决了我自己的问题.....我给输入字段不同的名字，如下所示，很简单。这不应该花我几天！

<input name="file" type="file" size="20" multiple="true" />
<input name="file2" type="file" size="20" multiple="true" />
<span><?php

if (isset($_POST['submit'])) {
ini_set( "display_errors", 0);
$file = uploadFile('file', true, false);
$file = uploadFile('file2', true, false);//added this line. 
if (is_array($file['error'])) {
$message = '';
foreach ($file['error'] as $msg) {
  $message = $msg;    
}
} 
echo $message;
}

?>

最后是成功消息部分

<?php

if (isset($_POST['submit'])) {

$file = uploadFile('file', true, false);
$file = uploadFile('file2', true, false);
if (!is_array($file['error'])) {
$message = '';
$sub=1;
$message = "<span class='isa_success'>File uploaded successfully</span>";

echo $message;
} 

}
?>

Answer 3

我已经为使用php中的单个文本框上传的多个图片创建了一个解决方案。

<form method="post" action="" enctype="multipart/form-data" id="frmImgUpload">
  <input name="fileImage[]" type="file" multiple="true" />
  <input name="btnSubmit" type="submit" value="Upload" />
</form>

<?php
  $i=1;
  if ($_POST)
  {
    foreach($_FILES['fileImage']['name'] as $key => $i)
    {
      $file_name = $_FILES['fileImage']['name'][$key];
      $file_size =$_FILES['fileImage']['size'][$key];
      $file_tmp =$_FILES['fileImage']['tmp_name'][$key];
      $file_type=$_FILES['fileImage']['type'][$key];
      move_uploaded_file($file_tmp,"uploaded_img/".$file_name);
      $i++;
    }
  }
?>
