Example of file upload function implemented by Thinkphp5+uploadify

In this paper, the file uploading function realized by Thinkphp5+uploadify is described as an example. Share it for your reference, as follows:

First contact with server-side development, while learning to try to do an OTA background server, it took a lot of effort to achieve file upload and progress bar display.

Encountered several problems:

1. Large file upload failed
2. Upload cancellation X match cannot be displayed
3. Don't know how to pass variable values to background php

Record the process:

1. Download the uploadify code to the project, such as public\ plug-ins\ uploadify.
2. The front-end script is as follows,

The client passes the version number in formData. Please see the version_id assignment method. You need to give it assign in the controller first.

Cancel the match can not be displayed, need to modify uploadify. css inside background: url('uploadify-cancel.png')

Note the writing of uploader in uploadify

<form enctype="multipart/form-data" method="post" >
  <input type="file" name="uploadify" id="uploadify" multiple="true" />
</form>
<script type="text/javascript">
  <?php $timestamp = time();?>
  var maxSize = 1024 * 1024*1024;//1G
  $(function() {
    $('#uploadify').uploadify({
      'debug'  : false,
      <span style="white-space:pre">   </span> 'fileSizeLimit ': maxSize,
      'formData'   : {
        'timestamp' : '<?php echo $timestamp;?>',
        'token'   : '<?php echo md5('unique_salt' . $timestamp);?>',
        <span style="white-space:pre">    </span>'version_id': "{$version_id}"
      },
      'swf'   : '/public/plug-ins/uploadify/uploadify.swf',
      <span style="white-space:pre">    </span>'cancelImg':'/public/plug-ins/uploadify/uploadify-cancel.png',
      'uploader' : '{:url("Package/upload")}',
      <span style="white-space:pre">    </span>'fileTypeDesc'  : 'zip Documents ',
      <span style="white-space:pre">    </span>'fileTypeExts' : '*.zip',
      <span style="white-space:pre">   </span> 'multi': false
    });
  });
</script>

3. The back-end script corresponds to the upload function of the controller Package

Pay attention to the acquisition method of uploaded files, and cannot use the acquisition method of Thinkphp5 official documents.

Save file name with no special symbol

Modify php. ini: upload_max_filesize = 1024M post_max_size=48 Restart service

public function upload(){
  $verifyToken = md5('unique_salt' . $_POST['timestamp']);
  if (!empty($_FILES) && $_POST['token'] == $verifyToken) {
  $tempFile = $_FILES['Filedata']['tmp_name'];
    /*
    $targetFolder = '/public/uploads'; // Relative to the root
  $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
  $targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
  // Validate the file type
  $fileTypes = array('jpg','jpeg','gif','png','zip'); // File extensions
  $fileParts = pathinfo($_FILES['Filedata']['name']);
  if (in_array($fileParts['extension'],$fileTypes)) {
    move_uploaded_file($tempFile,$targetFile);
    echo '1';
  } else {
    echo 'Invalid file type.';
  }*/
    $version = model("Version")->retrieve_by_version($_POST['version_id']);
    if($version){
      $file = new File($tempFile,'rw');
      $hash_code = $file->hash();
      $time = date("Y-m-d-i-s",$_POST['timestamp']);
      $info = $file->move(ROOT_PATH . 'public' . DS . 'uploads'.DS.$version['project_name'].DS.$version['version_name'],'update_'.$time.'.zip');
      if($info){
        //  After successful uploading,   Get uploaded information 
        echo $info->getExtension();
        echo $info->getSaveName();
        echo $info->getFilename();
      }else{
        //  Upload failed to get error message 
        echo $file->getError();
      }
    }else{
      echo ' The corresponding version could not be found ';
    }
  }
}
