Hi all,

 

I have a form which very nicely creates a folder on myserver named after the userid of the user that is logged in. IE user/4 and has an upload function. The code is:

 

<?php
    session_start();
    include('include/database.php');
    include('include/auth.php');

    $userid = $_SESSION['SESS_USERID'];
    $sql = "SELECT * FROM user WHERE userid = $userid";
    $result = mysql_query($sql) or die(mysql_error());

    if ($result)
    {
        while ($row = mysql_fetch_array($result))
        {
            $userid = $row["userid"];
            if (is_dir('users/'.$userid) == FALSE)
            {
                mkdir('users/'.$userid);
            }
        } 
    }
?><br />
<br />
<br />
Upload a Picture of your band!<br />
<br />

<form enctype="multipart/form-data" action="do/bandpicdo.php" method="post" name="changer">
<input name="MAX_FILE_SIZE" value="102400" type="hidden">
<input name="image" accept="image/jpeg" type="file">
<input value="Submit" type="submit">

 

 

Which of course then completes the action of uploading by loading file bandpicdo.php which currently contains:

 

<?php
session_start();
include('../include/auth.php');
include('../include/database.php');



 ?>

 

I am stumped!

 

 

What I want this to do is :

 

a) Upload the image submitted in the form

b) resize the image to 120x120

c) rename the image to 'mainpic.jpg'

4) save to the users directory

 

 

Ehm, Help!

runnerjp,

 

I can not thank you enough, I never expected anyone to be kind enough to write it for me! I will test it soon and come back to you if there is anything I dont understand, and thank you for the comments in the script, I am trying to learn by doing and that probably saved me hours of trying to work out what each peice of script is doing.

 

Again, Many many thanks

Ok mate,

 

Stumped again:

 

 <?php

$userid = $_SESSION['SESS_USERID'];
        if(isset($_POST['submit'])){
          if (isset ($_FILES['new_image'])){
                                  $file_name = $_FILES['new_image']['name'];

                $file_ext = $getExt[count($getExt)-1];
                                // Adding extension verification
                                $allowed_ext = "|jpg|png|gif|jpeg|svg|bmp|";
if (strpos($allowed_ext, "|".strtolower($file_ext)."|")===false) 
  die("Extension: $file_ext is not allowed!");             
                                // End extension verification           
                                $imagename = "mainpic.jpg";

              move_uploaded_file($source, $target);

              $imagepath = $imagename;
              $save =  "C:/wamp/www/fanjunky/users/$userid/$imagepath"; //This is the new file you saving
              $file =  "C:/wamp/www/fanjunky/temp/$userid/$imagepath"; //This is the original file

              list($width, $height) = getimagesize($file); 

              // Adding proportionate image resizing, with max values
                          
                  //  $modwidth = 200; $diff = $width / $modwidth; $modheight = $height / $diff; 
             
                          
                          $max_w = 120;
                          $max_h = 120;
                          
                          if($width <= $max_w && $height <= $max_h){ // if it fits
                     $modheight = $height; 
                                 $modwidth = $width;
                          }else{ // Then resize
                                $diff = ($width > $height) ? ($width/$max_w) :  ($height/$max_h); // Check which is bigger, and fit it to that max value. This will prevent stretching (80x800)
                    $modheight = $height / $diff; 
                                $modwidth = $width / $diff;
                          }
                          
                          // End 
                          
                          $tn = imagecreatetruecolor($modwidth, $modheight) ; 
              $image = imagecreatefromjpeg($file) ;

          }
        }
?>

 

This is giving errors:

Using this:

                                $allowed_ext = "|jpg|png|gif|jpeg|svg|bmp|";
if (strpos($allowed_ext, "|".strtolower($file_ext)."|")===false) 
  die("Extension: $file_ext is not allowed!");

                    $modheight = $height / $diff; 
                                $modwidth = $width / $diff;
                          }
                          
                          // End 
                          
                          $tn = imagecreatetruecolor($modwidth, $modheight) ;

                          imagejpeg($tn, $save, 100) ; 

            
                         
             
          }
        }
?>

 

It nows save to the folder without an error :)

 

However it has cropped the width to 120, but cropped the height to 14 pixels?

 

Any thoughts on that?

 

You are, by the way, my hero!
