[doforumda]

hi

 

i am trying to upload images and resize them to thumbnail size through imagecopyresampled. I allowing four kinds of images gif,jpg,jpeg and png. the problem is imagecopyresampled only works for jpg not for others. my code is below please help me out where i am making mistake

<?php
include("getExtension.php");
$filename = 'banner.gif';
$ext = getExtension($filename);
$ext = strtolower($ext);

$jpg = false;
$png = false;
$gif = false;
// Content type
if($ext=='jpeg' || $ext == 'jpg') { 
$jpg = true;
header('Content-type: image/jpeg');
}
if($ext=='png') { 
$png = true;
header('Content-type: image/png');
}
if($ext=='gif') {
$gif = true;
header('Content-type: image/gif');
}

// Get new dimensions
list($width, $height) = getimagesize($filename);
$new_width = 80;
$new_height = 80;

// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Output
if($jpg==true) {
imagejpeg($image_p, $save, 100);
}
if($png==true) {
imagepng($image_p, $save, 100);
}
if($gif==true) {
imagegif($image_p, $save, 100);
}
?>

 

above code displays this error

The image “http://localhost/imageResizer/image_resizer.php” cannot be displayed, because it contains errors.

Of course your code will only work for jpg images. Look at this line:

 

$image = imagecreatefromjpeg($filename); // can't use this on gif or png!

 

You need to to check the image type, if it's gif use imagecreatefromgif() or if it's a png then use imagecreatefrompng()

now it is working for jpg and gif but not for png

 

i modify my code and add these

if($jpg==true) {
$image = imagecreatefromjpeg($filename);
}
if($png==true) {
$image = imagecreatefrompng($filename);
}
if($gif==true) {
$image = imagecreatefromgif($filename);
}

No offense, but are the images you're loading png's/gifs etc?

 

Can you provide us with some of the error messages? It might be any number of reasons - file size is too large, image wasn't copied to location x...

now it just display this

http://localhost/imageResizer/image_resizer.php

 

no errors are displayed

now it just display this

http://localhost/imageResizer/image_resizer.php

 

no errors are displayed

 

Comment out imagepng/jpg/gif lines including header lines, and add error reporting. It will prevent the image from parsing, and send you an actual error. Obviously you can't see one if there is no domain for text to be displayed.
