Question

I am trying to resize an image that I have uploaded with a form. I am using the script scene here: http://www.white-hat-web-design.co.uk/blog/resizing-images-with-php/

I am also using the following code to upload the image:

upload.php:

    <?php

    session_start();
    require_once "database.php";
    db_connect();
    require_once "auth.php";
    $current_user = current_user();

    $emailstring = $current_user['email'];

//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", "image/png");

    if (in_array($file['type'], $valid_types))
        return 1;
    return 0;   

}

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 = "profile_images/";

//Get our POSTed variables
$upload_picture_fileinput = $_FILES['upload_picture_fileinput'];


//Sanitize input
$upload_picture_fileinput['name'] = mysql_real_escape_string($upload_picture_fileinput['name']);

//Build our target path full string.  This is where the file will be moved to
//i.e. profile_images/picture.jpg
$TARGET_PATH .= $upload_picture_fileinput['name'];

if(!is_valid_type($upload_picture_fileinput)) {

    $_SESSION['error'] = "You must upload a jpeg, gif, bmp, or png";
    header("Location: account.php");
    exit;


    }

//attempt to move the file from its temporary directory to its new home
if (move_uploaded_file($upload_picture_fileinput['tmp_name'], $TARGET_PATH)) {

    $sql = "UPDATE `users` SET `profile_image_filename`='" . $upload_picture_fileinput['name'] . "'
                       WHERE email='$emailstring'";


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

    header("Location: account.php");
    exit;
}
else 
{


    $_SESSION['error'] = "Could not upload file.  Check read/write permissions on the directory";
    header("Location: account.php") ;
    exit;

    }

and where my form is:

<div class="pictures add_pictures">
            <div class="add_picture">
                <div class="upload_picture">
                    <form action="upload.php" method="POST" enctype="multipart/form-data" name="upload_picture_form" class="upload_picture_form">
                        <span class="add_picture_label">+ Add a Profile Picture</span>
                        <input type="file" name="upload_picture_fileinput" class="upload_picture_file_input"/>
                        <input type="hidden" name="MAX_FILE_SIZE" value="100000"/>
                        <br><br><br><br><br><br><br>

                        <input type="submit" id="submit" value="Upload" />
                    </form>
                </div>
            </div>
        </div>

        <?php

            $sql = "select * FROM `users` WHERE `id`='$id'";
            $result = mysql_query($sql) or die ("Could not access DB: " . mysql_error());



                $row = mysql_fetch_assoc($result);


                echo "<p>";

                echo "<img src=\"profile_images/" . $row['profile_image_filename'] . "\" alt=\"\" /><br />";
                echo "</p>";



        ?>
                                    //not currently working
                <img src="/imageresize.php"/>

The echo above prints the picture out fine, but when I try to use that filename to resize the image, it does not appear/work.

<?php
    session_start();
    require_once "database.php";
    db_connect();
    require_once "auth.php";
    $current_user = current_user();

    $resized_image = '\"profile_images/" . $row['profile_image_filename'] . "\" alt=\"\" /';

    header('Content-Type: image/jpg');
    include('SimpleImage.php');
    $image = new SimpleImage();
    $image->load($resized_image);
    $image->resizeToWidth(300);
    $image->output();


?>

I am connecting to the database fine and the image filename is being saved in my database. I just don’t know why the file path above will print the picture, but not work in the resize script. Please help if you can. Thank you.

Looks like in $resized_image you have added the html alt tag which should, of course, not be part of the parameter you are feeding into $image->load($resized_image);.

Try changing this to

$image->load('profile_images/' . $row['profile_image_filename']);

instead of the string that already targets the html rendering.
