Hey some js files are missing...

There is only php file in the download script

To Niju Mohan: this code does not require javascript at all, which is why it's so good. Pure PHP excellence!

hello i m jack here i just see u php tutorial ,upload and resize an image with php ,but i face a problem i using the script to upload a png
files format but after upload my files background is black colour. the oroginal files is transparency.how to make the png files still keep the transparency? thank you .

thanks

The jsquery does not download while downloading the script can you help it.....

Thanks, really helped me out! To set both a max width and height of 500 and 350 I added this:

$newwidthX=500;
$newheightX=($height/$width)*$newwidthX;
if($newheightX > 350) {
$newheight=350;
$newwidth=($newwidthX/$newheightX)*$newheight;
} else {
$newheight = $newheightX;
$newwidth = $newwidthX; }

Actually i am a java programmer. But now working in PHP. This article was very much useful for me..

very nice and simple..

Hi i need to know the following, what if two users have different photos with the same name?

Is there anyway to put the users ID number in front of the picture? Or rename the picture to there userid/pic.jpg?

good work, thanks for the code. I've just addapted it for our gallery on our site.

hi again,
sometimes it's important to upload with a unique image name.

maybe you should add this part to your code for this;

i've changed this block;

$filename = "img/". $_FILES['file']['name'];

$filename1 = "img/small". $_FILES['file']['name'];

with this;

$image_name=time().'.'.$extension;

$filename = "img/". $image_name;

$filename1 = "img/small_". $image_name;

to upload images with a unique name via using time().

First of all thanks!

I have a question!
When I upload png or gif with transparency it turns the transparency black. Do you know any solution to make it transparent again?

i want to display image from database..any idea?

Do you have any answer on how to get the transparency right in uploaded pictures?

If not just say it so I don't have to come back and look if you have answered.

Hvala, ti, res dobra in enostavna skripta.

Tnx you, realy nice and easy script.

thanks for the script

where image create ?

i am not able to find created image

yes me too, i'm not able t find where they stored image...

<?php echo ("Testing can you use php in comments"); ?>

This is great! Thanks for this. 2 thumbs up!

thanks .. its help me too much today :)

Awesome script, worked out of the box for me.. with a few minor changes I have it doing unique ident image names + store to MySQL, so it really fits what we are trying to achieve.

Cheers,

Why does this fail for large file sized images? For example, I can upload all the windows sample pictures which range in size from 27 KB to 103 KB. However, I can’t upload an image that is 1 MB such as this one http://tinyurl.com/yg4zfak

I believe it hangs up on the line $src = imagecreatefromjpeg($uploadedfile); (or png, gif).

How can I make it so this script will allow all sizes of images?
Thanks.

thanks for the script! :)
question: what if i have multiple images? should i just create several input boxes? err.. help! :P

your script so cool but i think beginners must modify this script a little bit simply by adding 'move_uploaded_file()' function and must create a directory name 'images'


kind regards and thanks for sharing!

excellent man, works good. thanks for the example

nice script and as stated above this is alot for newbies if you could please help with how and where the changes could go am a learn as you go and am building my site from tutorials, so if you could please help as to where in page this goes so that the images could show I would really appreciate it my site is not up yet but am gonna place this code in the section so that visitor could post there pics of the party they have being and so! its gonna go on the section called subetusfotos.html Thanks Maria and Rey

hi. what about if i would like upload 2 or more photos? what to do? i`m new in php:/ help pls..
regards

very good stuff buddy !

to solve the png transparency
new width and heigt are ratios that i am working with
$temp=imagecreatetruecolor($newwidth,$newheight);

if($extension=="jpg" || $extension=="jpeg" ){
$img=imagecreatefromjpeg($upload);
imagecopyresampled($temp,$img, 0, 0, 0, 0,$newwidth,$newheight,$width,$height);
imagejpeg($temp,$path,100);
}
else if($extension=="png"){
$img=imagecreatefrompng($upload);
imagecopyresampled($temp,$img,0,0,0,0,$newwidth,$newheight,$width,$height);
imagepng($temp,$path);
}
else if($extension=="gif"){
$img=imagecreatefrompng($upload);
imagecopyresampled($temp,$img,0,0,0,0,$newwidth,$newheight,$width,$height);
imagepng($temp,$path,100);
}

Nice one!
Only if you're file is to big, then he will also store it.. I build in a specification while it is exists or not and even a max height..

Thanks a lot dude!

".$filename1;

if(file_exists($filename)) {
$change='Het bestand '.$filenam.' bestaat al.';

}
elseif(file_exists($filename1)){

$filename = stripslashes($_FILES['file']['name']);

imagedestroy($src);
imagedestroy($tmp);

}}

}
}//Als bestandgrootte kleiner is dan 1 MB
}//als de bestanden nog niet bestonden.
//If no errors registred, print the success message
if(isset($_POST['Submit']) && !$errors)
{

// mysql_query("update {$prefix}users set img='$big',img_small='$small' where user_id='$user'");
$change=' Image Uploaded Successfully!';
}

I have a better solution for the png transparency
else if($extension=="png"){
$img=imagecreatefrompng($upload);
//If our image have white background imagealphablending($temp,false);
//we capture the bg of our image $color=imagecolorallocatealpha($temp, 0, 0, 0, 127);
//fill the bg we capture before to put it in the resized one
imagefill($temp,0,0,$color);
//we restore the transparency(bg) imagesavealpha($temp,true);
//then we follow the steps of our friend =) imagecopyresampled($temp,$img,0,0,0,0,$newwidth,$newheight,$width,$height);
imagepng($temp,$p.'_m'.".".$extension); I hope it helps you :D
move_uploaded_file($upload,$p.".".$extension);

nice, i want to make an image resize but like (50x50, 20x20,...).
thanks..

Yeah! I got it finally...Thank u very much...I was facing a problem with resizing images since 2 days and your script helped me to complete my task..

Hi,

Thanks for the script. I just cant get it working though?

I have made a folder called images and one inside that called small.

Im testing it but nothing happens. IT just says its uploaded successfully except the images folder is empty.

Please help

yes me aswell - It says "uploaded successfully" but not an image being placed in the images folder on mine ftp.... me too I think is something wrong with what Im doing here?

Thanks man! I'm from Brazil!
I love the web too!!!

To get file extension just need a bit code :

$ext = substr(strrchr("hello.php", "."), 1);

Dude, you rock. I got this working on the first try! Much love.

How to add multiple images?

What happens when an image already exist with the file name? As I see it's doesn't upload an image if another image is already uploaded with the same name... Is it possible to rename uploaded image if another image already exists?

Did someone already found a solution for the black .GIF output?

Thanks for the script b.t.w, it really helped me a lot!

@ John:

Remember to give permissions to folders, the file wont upload to the server if you dont give the right permissions.

@Srinivas

Thanks friend, you helped me a lot.

@ every reader

If you are using a form to store data in the server and in the database, you may be using an ID for each entry to the DB, just include the ID and that way you will be able to find who or which entry the image belongs to.

works great, thanks!

there are missing some js files ?!
Or clear script code !

hi
can u give me d code to add watermark to images?
thanks in advance

Bug:
$scr -> $src

Mirko

Hi,

It will be helpfull for slower connections.??
