could someone help in how to resize a uploaded image size, say if someone is uploading a 1mb photo to my server, i wish for it to become 100kb and also resize its width and height?

here is my code

Code: [Select]
//////////////////////////////////////uploader
else if($action=="uploader")
{



echo "Upload your picture and copy the link <br/>after uploading to user it at gallery.<br/><br/>";

echo "<form method=\"post\" enctype=\"multipart/form-data\" action=\"index.php?action=uploaded&amp;sid=$sid\">";
echo "Choose Pictu <br />";
echo "<input name=\"uploaded\" type=\"file\" /><br /><br />";
echo "<input type=\"submit\" value=\"Upload\" />";
echo "</form><br/>";


echo "<p align=\"center\">";
echo "<a href=\"index.php?action=main&amp;sid=$sid\">Home</a>";
echo "</p>";
}


//////////////////////////////////////uploader
else if($action=="uploaded")
{



$blacklist = array(".php", ".php.jpg", ".php.jpeg", ".php.gif", ".php.png", ".phtml", ".php3", ".php4");
foreach ($blacklist as $item) {
if(preg_match("/$item\$/i", $_FILES['uploaded']['name'])) {
echo "<p align=\"center\">";
echo "Oops sorry we do not allow those files.<br/>";
echo "<a href=\"index.php?action=main&amp;sid=$sid\">Home</a>";
echo "</p>";
exit;
}
}

$target = "../images/";
$target = $target . basename( $_FILES['uploaded']['name']) ;
$ok=1;

if (file_exists("../images/" . $_FILES["uploaded"]["name"]))
      {
echo "<p align=\"center\">";
      echo $_FILES["file"]["name"] . "Oops file name already exists<br/> kindly rename your picture and upload again. <br/>";

echo "<a href=\"index.php?action=main&amp;sid=$sid\">Home</a>";
echo "</p>";   
 }else{

//This is our size condition
if ($uploaded_size > 25600){

echo "Your file is too large. We have a 25kb limit.<br/>";
$ok=0;
}

$types = array('image/jpeg', 'image/gif', 'image/png');

if (in_array($_FILES['uploaded']['type'], $types)) {
// file is okay continue
} else {
$ok=0;
}


//Here we check that $ok was not set to 0 by an error
if ($ok==0){
echo "<p align=\"center\">";
Echo "Sorry your file was not uploaded.<br/> It may be the wrong filetype. <br/>We only allow JPG, GIF, and PNG filetypes.<br/>";

echo "<a href=\"index.php?action=main&amp;sid=$sid\">Home</a>";
echo "</p>";
}

//If everything is ok we try to upload it
else{
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)){
echo "<p align=\"center\">";

echo "The file ". basename( $_FILES['uploadedfile']['name']). " Picture uploaded successfully.<br/><br/><b>$target <br/>";

echo "<a href=\"index.php?action=main&amp;sid=$sid\">Home</a>";
echo "</p>";
}
else{
echo "<p align=\"center\">";

echo "Sorry, there was a problem uploading your file.<br/>";
echo "<a href=\"index.php?action=main&amp;sid=$sid\">Home</a>";
echo "</p>";
}
}
}
}

The script for creating a new file name for the image:

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image

The script creates a new file like:

f6c9b8d9db05366c3504210cded9ddb2.jpg

and moves the file to the "uploads" folder. And then the script also creates a thumbnail with the same file name and moves the file to the "thumbs" folder.   The issue I am having is that the same ID code could happen again for a different image in the database, thus I would be calling a different original sized image than the thumbnail image.   My question is: How to avoid this issue of the same ID code has happened again for a different file. What is the proper way to reference the anchor tag of the thumbnail image to its actual original sized image?   With the script I have the thumbnail image would be coming from the "thumbs" folder and the anchor tag would get referenced to the "uploads" folder to get the original sized image.

Well the subject line is pretty explicit.  I found this script that uploads a picture onto a folder on the server called images, then inserts the the path of the image on the images folder onto a VACHAR field in a database table. 
Code: [Select]




<?php

//This file inserts the main image into the images table.

//address error handling

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);





//authenticate user
//Start session
session_start();

       
        //Connect to database
require ('config.php');

//Check whether the session variable id is present or not. If not, deny access.
if(!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) {
header("location: access_denied.php");
exit();
}

        else{ 







// Check to see if the type of file uploaded is a valid image type

function is_valid_type($file)

{

     // This is an array that holds all the valid image MIME types

     $valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif");

 

     if (in_array($file['type'], $valid_types))

         return 1;

     return 0;

}

 

// Just a short function that prints out the contents of an array in a manner that's easy to read

// I used this function during debugging but it serves no purpose at run time for this example

function showContents($array)

{

     echo "<pre>";

     print_r($array);

     echo "</pre>";

}

 

// Set some constants

 

// This variable is the path to the image folder where all the images are going to be stored

// Note that there is a trailing forward slash

$TARGET_PATH = "images/";

 

// Get our POSTed variable

$image = $_FILES['image'];

 

// Sanitize our input

$image['name'] = mysql_real_escape_string($image['name']);

 

// Build our target path full string.  This is where the file will be moved to

// i.e.  images/picture.jpg

$TARGET_PATH .= $image['name'];

 

// Make sure all the fields from the form have inputs

if ( $image['name'] == "" )

{

     $_SESSION['error'] = "All fields are required";

     header("Location: member.php");

     exit;

}

 

// Check to make sure that our file is actually an image

// You check the file type instead of the extension because the extension can easily be faked

if (!is_valid_type($image))

{

     $_SESSION['error'] = "You must upload a jpeg, gif, or bmp";

     header("Location: member.php");

     exit;

}

 

// Here we check to see if a file with that name already exists

// You could get past filename problems by appending a timestamp to the filename and then continuing

if (file_exists($TARGET_PATH))

{

     $_SESSION['error'] = "A file with that name already exists";

     header("Location: member.php");

     exit;

}

 

// Lets attempt to move the file from its temporary directory to its new home

if (move_uploaded_file($image['tmp_name'], $TARGET_PATH))

{

     // NOTE: This is where a lot of people make mistakes.

     // We are *not* putting the image into the database; we are putting a reference to the file's location on the server

     $sql = "insert into images (member_id, image_cartegory, image_date, image) values ('{$_SESSION['id']}', 'main', NOW(), '" . $image['name'] . "')";

     $result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error());

     header("Location: images.php");

echo "File uploaded";

     exit;

}

else

{

     // A common cause of file moving failures is because of bad permissions on the directory attempting to be written to

     // Make sure you chmod the directory to be writeable

     $_SESSION['error'] = "Could not upload file.  Check read/write persmissions on the directory";

     header("Location: member.php");

     exit;

}







        } //End of if session variable id is not present.
 


?> 


The script seems to work fine because I managed to upload a picture which was successfully inserted into my images folder and into the database.
Now the problem is, I can't figure out exactly how to write the script that displays the image on an html page. I used the following script which didn't work.


Code: [Select]

//authenticate user
//Start session
session_start();

       
        //Connect to database
require ('config.php');

$sql = mysql_query("SELECT* FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main' ");
$row = mysql_fetch_assoc($sql);
$imagebytes = $row['image'];
header("Content-type: image/jpeg");
print $imagebytes;







Seems to me like I need to alter some variables to match the variables used in the insert script, just can't figure out which.  Can anyone help??

I don't usually post on "introduce yourself" type areas of forums. But I'm glad I found this place. It's nice to find a community not overrun by trolls and attitudes (ie, Stackoverflow). That's getting sadly rarer lately.   I've been writing/editing PHP for the past 8+ years now, but I still find things I've never done before. Hey, we can't know it all!   Before PHP, I mostly did ASP -- all the way back to my NT4 days.   I see a lot of hosting-related questions around here -- one of my areas of expertise -- so I think I'll stick around to help others.
