    My first shot at writing a class

    in PHP Coding Help

    Posted

    "Why would Image extend Uploader? They don't seem at all related." its simple, uploader uploads the file and image manipulates the file uploaded, you can have a subclass called videos extending from uploader as well as pdf and other mime types etc. its unlimited ideas that can be spawned.

    My first shot at writing a class

    I also added a image re-sizer for those that are interested in resizing an image and sending it to a new path, it was a challenge creating this and i know its buggy thats why i seek a community such as this one to help me to find them and we can all share good code to make our work flow faster.

     

    Antway here is the class, call it uploader_bk.php

     

    <?php 

/* 
   This is a simple file uploader class created by me: Hugo Johnson
   website: www.jwmstudios.com
   email: hugoj@hotmail.com 
   
   Its my first real shot at creating a php class, i am still a todler to this. 
   
   The Class called uploader is responsible for creating a file field and a single form, or many file fields (without a form) 
   It then uploads the chosen file to a specified path, once you click on the browse button and submitt the form. 
   
   The Sub-Class called Image is used to both upload the image to a chosen path as well as create a thumbnailed copy
   this thumbnail can be resized based of the new height parameter that is passed in by the user.
   
   Needs more work and validation but enjoy.

      Class Uploader  {
    
    // Declaring my variables needed for this class, it makes sense. 
    public   $input_field_name = "userfile";  // default input field name 
    public   $file_size =300000;  // default file size 
    public   $path_directory = "";  // location to send the file 
    public   $action_path_and_file = "uploader.php";  // default form action

   
    
    function  form() {  // This form is optional used if no form is provided, only good for one file 
        
            echo <<<END

    my next mission is to fuse it with  a MySQL Class so that i can reference the files in a database and also a remover function that will remove my files from both the server and the database, some assistance / guidance will be greatly appreciated.

    Solving the issues with global variables turned off

    Ok i modified the get page using unset as suggested, it worked!

     

    <?php
   
   // Start Your Session each time save this file as get.php 
   session_start();

   $name = $_SESSION['name'];   // this is the original variable data that you want to store
  
   echo "my name is ".$name;  // output on screen  
  
   unset($_SESSION['name']);   // resetting my session variable using unset function
  
   if(!isset($_SESSION['name'])) {
    
   $_SESSION['name'] = "Joe";  // reassign session variable to joe     
      
  }
  
  
  
  echo "<br /><a href=\"testpost.php\" >go back</a>";
  
  
  
?>

    Ok after a few weeks of frustration i figured out how to get my variables to go back and forth pages without using register_globals = on

     

    ok here is some test code:

     

    First create a file called testpost.php

     

    copy and paste this data:

     

    <?php
  
  
   session_start();
      
  
    echo "<a href=\" get.php \" >Click here </a><br />"; 
   
    // looking for a returned value named Joe 
    if ($_SESSION['name'] == "Joe") {
       
       echo "Well What do you know i am".$_SESSION['name']."<br />";    // output on screen 
   }        
    
   // Well if i didn't find it, just call it mary. 
   $_SESSION['name']   = "mary";      
   
    
  
?>

     

    fine then create  another file in the same directory called get.php 

    copy and paste this into it:

     

    <?php
   
   // Start Your Session each time save this file as get.php 
   session_start();

   $name = $_SESSION['name'];   // this is the original variable data that you want to store
  
   echo "my name is ".$name;  // output on screen  
  
   $_SESSION['name'] = "";   // resetting my session variable
  
   if($_SESSION['name'] == "") {
    
   $_SESSION['name'] = "Joe";  // reassign session variable to joe     
      
  }
  
  
  
  echo "<br /><a href=\"testpost.php\" >go back</a>";
  
  
  
?>

     

    ok give it a test and then modify as you like, you don't have to send your variables across your web browser dudes, enjoy!

    batch processing images using php

    The Problem with those applications the code seem complex as they use complex classes with xml and they don't comment on functionality within their code, but i created this thread with the hope that someone out there has been through this roadblock before and have useful code.

     

    I will post my findings to this thread when i get through.

    batch processing images using php

    in PHP Coding Help

    Posted

    Hello everyone  ;D

     

    I have built a photo gallery application, but i would like to add a feature where i can manually create a folder within a directory and php is able to detect the files for me and also generate thumbs (previews). I can then choose which file i want to include in my database eg album, category etc.

     

    I sort of want it to function like coppermine photo gallery admin tools.

     

    Is there any code that i can start with?

    PHP and Directories

    I am looking for a script similar to yours, but am not sure how to get the php to detect the jpgs once the files are uploaded, i have an idea of how to resize an image using php, i am currently following this article:

    http://www.sitepoint.com/article/image-resizing-php

    Creating the directory i know can be done with mkdir() i can easily put the pathname in a database and create a type of index and tag it to each photo uploaded.

    But my problem is php detecting the jpg file and generating the thumbnail.

    If you can assist me i would really appreciate.
