    Uploading a file in your application can be used to upload an image or documents.

    With the help of the cakephp html we can create a form with the input field of type file which allows to browse and select the file from your systems.

    lets create a cakephp html form for the same ,

    <center>
    <div class="users view">
    
    <h2><?php echo('User'); ?></h2>
    <?php
    
          echo $this->Form->create('uploadFile', array('type' => 'file'));  //input field of type file allows browse your file. 
        echo $this->Form->input('pdf_path', array('type' => 'file','label' => 'Pdf')); 
        echo $this->Form->end('Upload file');
    
         $image_src = $this->webroot.'img/'.$image;
    ?>
    
    <img src="<?php echo $image_src;?>">
    
    </div>
    </center> 
    

    In the controller create a function that performs the overall task of uploading the file ,

    public function upload_file() {
    
      $filename = '';
    
    
         $uploadData = $this->data['upload_File']['pdf_path'];
         if ( $uploadData['size'] == 0 || $uploadData['error'] !== 0) { 
           return false;
         }
    
         $filename = basename($uploadData['name']);
         $uploadFolder = WWW_ROOT. 'img';  
         $filename = time() .'_'. $filename; 
         $uploadPath =  $uploadFolder . DS . $filename;
    
         if( !file_exists($uploadFolder) ){
           mkdir($uploadFolder); 
         }
    
         if (!move_uploaded_file($uploadData['tmp_name'], $uploadPath)) {
           return false;
         } 
    
      }
    
      $this->set('image',$file_name1); 
    
    }
    

    In the above code of the controller the statement $uploadData = $this->data['upload_File']['pdf_path']; will fetch the uploaded file path from the form filed of type file and assign it to the $uploadData. same way the below statements dose for file name webroot path etc..


    $filename = basename($uploadData['name']); this statement will fetch the file name and assign it to the $filename.

    $uploadFolder = WWW_ROOT. 'img'; this statement will set the webroot path with the folder name where the file is to be uploaded.

    $filename = time() .'_'. $filename; this statement append the random no before the file name so that it wont get conflict from already existing file with the same name, it protects from re-writing the file.

    $uploadPath = $uploadFolder . DS . $filename; Finally this statement will save the whole path where the file to be uploaded with the new file name.

    finally the key statement move_uploaded_file($uploadData['tmp_name'], $uploadPath) have the function move_uploaded_file() which takes the two statements first one is the temp file path and second one is the original file name and then uploads the file on the original location.
