PHP - Create Thumbnail From Uploaded Image

Hello

I have uploaded images from a server onto a website, they run through a mysql database (database holds the image file names). The problem I am having is resizing the images. Can anyone help?

Thank you in advance

Hi everyone, I have a script below, which uplads an image, however, the image name always starts with a capital letter, I want all letters to be small, how to adjust this please, thank you

 

$target_dir = "";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$target_file = "$get_current_user.jpg";


$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));


// Check if image file is a actual image

if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo ""; /// was File is an image
        $uploadOk = 1;
    } else {
        echo "File is not an image<br>";
        $uploadOk = 0;
    }
}


// Check file size

if ($_FILES["fileToUpload"]["size"] > 10000000) {
    echo "Sorry, this image is too large, please resize using Paint<br>";
    $uploadOk = 0;
}

// Allow certain file formats

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {
    echo "Only JPG, JPEG, PNG & GIF files are allowed<br>";
    $uploadOk = 0;
}


// Check if $uploadOk is set to 0 by an error

if ($uploadOk == 0) {

    echo "There was an error<br>";


} else {


    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {

       echo "Uploaded successfully (You may need to clear Cache to see the new image)";
	   mysql_query("UPDATE user SET user_image = 'https://.../images/users/$get_current_user.jpg' WHERE user_name = '$get_current_user' ");

    } else {

        echo ""; /// was Select a suitable image, file not uploaded yet

    }

}

 

I'm beginning with simple codes to understand how things work and work my way up with what I need.

My upload form looks like this:

<form name="upload about" action="display.php" enctype="multipart/form-data" method="post">
Header: <input type="text" name="header" />
Body: <input type="text" name="body"  />
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
Image: <input type="file" name="pic"  />
<input type="submit" />
</form>

And my display page is just as simple.

<?php echo $_POST["header"]; ?>
<?php echo $_POST["body"]; ?>
<?php echo $_FILES['pic']['name']; ?>

The problem is, whenever I submit the data, everything is fine, except the image does not display and just posts the filename of the image I uploaded.
According to my research setting the enctype to multipart/formdata should display the image, but it does not. Can anyone tell me what's wrong?

Hello. I'm using an Amazon S3 class to uploaded to S3. I have 2 upload boxes - The first uploads once and the second needs to upload twice - 1 full size, 1 thumb.

The issue i'm having is that the 2nd image (the thumb) seems to be failing, although if I don't save the first full sized image I am able to upload the thumb. So I think the issue is with using the temp file twice?

This is my code:

 //retreive post variables

$fileName = $randomString . "_" . $_FILES['theFile']['name'];

$fileTempName = $_FILES['theFile']['tmp_name'];

$fileName2 = $randomString . "_" . $_FILES['theFile2']['name'];

$fileTempName2 = $_FILES['theFile2']['tmp_name'];

    //move the file

if ($s3->putObjectFile($fileTempName, "containerhere", $fileName, S3::ACL_PUBLIC_READ)) {

echo "<strong>Uploaded Image</strong>";

}else{

echo "<strong>Something went wrong while uploading your file... sorry.</strong>";

}

//move the file

if ($s3->putObjectFile($fileTempName2, "containerhere", $fileName2, S3::ACL_PUBLIC_READ)) {

echo "<strong>Uploaded Image</strong>";

}else{

echo "<strong>Something went wrong while uploading your file... sorry.</strong>";

}

  include('simpleImage.php');

  $image = new SimpleImage();

  $image->load($_FILES['theFile2']['tmp_name']);

  $image->resizeToWidth(100);

  $image->save($_FILES['theFile2']['tmp_name']);

$fileName3 = $randomString . "_" . $_FILES['theFile2']['name'];

$fileTempName3 = $_FILES['theFile2']['tmp_name'];

//move the file

if ($s3->putObjectFile($fileTempName3, "containerhere", "thumbs/" . $fileName3, S3::ACL_PUBLIC_READ)) {

echo "<strong>Uploaded Image</strong>";

}else{

echo "<strong>Something went wrong while uploading your file... sorry.</strong>";

}

Can anyone offer any advice?

Thanks.

I have a form where you can enter a image url and it's title. It calls display.php which displays the image as well as the title.
But I want the image to be displayed as a thumbnail of size 150X100.
Do i have to store it in directory before I convert it and display? If so, can somebody tell me how to convert the image into a thumbnail?

Here is my code:

Code: [Select]
<table align="center" bgcolor="silver">
<form action="display.php" method ="post">
<tr>
<td align="center"><b><font color="#214754" size="3">Reg</font></b></td>
</tr>
<tr>
   <td> Title: </td>
   <td><input type="text" size ="40" name="registry_title1" /></td>
</tr>
<tr>
   <td> Image URL: </td>
   <td><input type="text" size ="40" name="registry_img1" /></td>
</tr>

<tr>
  <td>
    <input type="submit" name="submit" value="submit" />
 </td>
</tr>
</form>
</table>
</div>
here is the code for display.php
Code: [Select]
<?
/* Get Registry details */

$registry_img1=$_POST['registry_img1'];
$registry_title1=stripslashes($_POST['registry_title1']);
?>

<html>
<body>
<table width='600' cellspacing='0' cellpadding='0' border='0' bgcolor='#ffffff' align='center'>
      <tr>
      <td style='padding-bottom:8px';><font style='font-size:18px;color:rgb(0, 0, 0);text-decoration:none'><a style='font-size:18px;color:rgb(0, 0, 0);text-decoration:none' href='#'><? echo ucfirst($url); ?> Registry</font></a></td>
      </tr>

   <tr>
      <td style='padding-bottom:10px;'>
      <a style='color:rgb(206, 0, 0);font-size:14px;font-weight:bold;line-height:18px;text-decoration:none' href='<? echo $registry_url1; ?>' target='_blank'><img style='padding-right:10px' border='0' align='left' alt='' src='<? echo $registry_img1; ?>'><? echo $registry_title1;?>
      </a>
      </td>
   
</table>

</body>
</html>

Help me

I am getting
Notice: Undefined index: extension

Im trying to write an image upload script which checks various elements of the image and then saves it and and a thumbnail into a folder.

At the moment I am getting a white screen which makes me think I have a syntax error so I have come here to find some fresh eyes to help me out. Can anyone see any reason why this wouldn't be working?

OK,

When the user fills the info in the form out it goes in the DB fine.  I can then array them on the "showroom page" fine.

When they upload a picture it goes into the /images/ folder fine.

Problem is... On each array on the showroom page I need the image they uploaded to be displayed.

Cant work it out.

Help would be GREAT!!!!!

Hey guys!
I have the following php code that grabs variables (and the browsed image) from Flash.


//FLASH VARIABLES
$Name = $_POST['Name'];
$itemNumber = $_POST['itemNumber'];
$filename = $_FILES['Filedata']['name'];
$filetmpname = $_FILES['Filedata']['tmp_name'];
$fileType = $_FILES["Filedata"]["type"];
$fileSizeMB = ($_FILES["Filedata"]["size"] / 1024 / 1000);


list($filename, $extension) = explode('.', basename($_FILES['Filedata']['name']));
$filename = $Name;
$target = $filename . $itemNumber . "." . $extension;


// Place file on server, into the images folder
move_uploaded_file($_FILES['Filedata']['tmp_name'], "images/".$target);



This works perfect, but what I want to change is the width and height of the uploaded image.
Any ideas/suggestions on how this could be done?

Thanks in advance!!
Cheers!

Hi

Basically I've built a CMS where by my clients can upload a number of images. On the success page I want to display the images they uploaded by file name.

The issue is the number of images can vary. They may upload 2 or 10 or 50 etc.

So far I've come up with this:

Code: [Select]
// number of files
$UN = 3; //I've set this to 3 for now, but this is passed from the upload page!

// server directories and directory names
$dir = '../properties';

$images = glob($dir.'/*.{jpg}', GLOB_BRACE); //formats to look for

$num_of_files = $UN; //number of images to display from number of uploaded files

foreach($images as $image)
{
$num_of_files--;

$newest_mtime = 0;
$image = 'BROKEN';
if ($handle = @opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != '.') && ($file != '..')) {
$mtime = filemtime("$dir/$file");
if ($mtime > $newest_mtime) {
$newest_mtime = $mtime;
$image = "$file";
}
}
}
}

if($num_of_files > -1) //this made me laugh when I wrote it
echo $trimmed = ltrim($image, "../properties").'<br />'; //display images
else
break;
}
Without this piece of code:

Code: [Select]
$newest_mtime = 0;
$image = 'BROKEN';
if ($handle = @opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != '.') && ($file != '..')) {
$mtime = filemtime("$dir/$file");
if ($mtime > $newest_mtime) {
$newest_mtime = $mtime;
$image = "$file";
}
}
}
}
It shows the first 3 files alphabetically. I want to view the last number of images added.

With the above code it simply shows the last image added 3 times!

So I need to get the time each image was added and then order by the newest added and limit to the number of images uploaded. Any suggestions please?

Kindest regards
Glynn

hi to all.Im currently displaying the images from my upload directory but the image does not display.please help thanks

Hi, I am trying to make a simple thumbnail gallery where you upload an image, the image gets resized, a thumbnail is created in the "images/small/" directory, and the main images are in the "images/" directory.

I need to somehow read from both directories, and do an image link with  the thumbnail linking to the larger image. I think that means displaying from two directories, I don't know how to do that, please any help greatly appreciated. Thank you.

here is my code so far

I am working on an uploader and slowly getting it working, I am uploading 3 images at once, and setting arrays for each one as keys, with an increment of ++1. I am wanting to resize the image before it gets copied to the thumbnail folder.

I have this code.

<?php

if (isset($_POST['addpart'])) {


    $image = $_FILES['images']['tmp_name'];

    $name  = $_POST['username'];

    $i     = 0;

    foreach ($image as $key) {


        $fileData   = pathinfo(basename($_FILES["images"]["name"][$i]));

        $fileName[] = $name . '_' . uniqid() . '.' . $fileData['extension'];

        move_uploaded_file($key, "image/" . end($fileName));


    //get uploaded file info before we proceed with resize

    $image_name = $_FILES['images']['name'][$i]; //file name

    $image_size = $_FILES['images']['size'][$i]; //file size

    $image_temp = $_FILES['images']['tmp_name'][$i]; //file temp

    $image_size_info    = getimagesize($image_temp); //gets image size info from valid image file



        copy("image/" . end($fileName), "image_thumbnail/" . end($fileName));

        $i++;

    }

    echo 'Uploaded<br>';

    echo 'Main Image - ' . $fileName[0] . '<br>';

    echo 'Extra Image 1 - ' . $fileName[1] . '<br>';

    echo 'Extra Image 2 - ' . $fileName[2] . '<br>';

    echo '<hr>';


}

?>

Everything works with it. As you see, I started on getting the file info, but after that I am totally stuck on what to do after to resize the image proportionally with a maximum width of xPX and height to match it without looking distorted.

Any help would be really appreciated. Thank You.

I need help making the uploaded image file name, that's chosen to be uploaded, be displayed on the html page with the path /upload/ added to the beginning of the displayed file name like so:

I am working on a simple gallery. I want to have an option to download full scale image without users having to right click and "save as". Using this code you get a image preview:

<a href="pictures/img-(1).jpg"><img src="thumbnails/img-(1).jpg"></a>

How can I modify it so when user clicks on thumbnail of image 1 it will prompt him to save the image instead of viewing it.

Thanks
