Display Jpeg image problem

[thefall]

Hi.

 

I have a problem where when i try to display the uploaded JPEG file, the browser would only dispay the placeholder for an image . I think the problem is within the 3rd IF statement.

 

Please help me thanks.

<?php

if($_SERVER['REQUEST_METHOD'] == 'POST') {


if(isset($_FILES['photo'])
&& is_uploaded_file($_FILES['photo']['tmp_name'])
&& $_FILES['photo']['error']==UPLOAD_ERR_OK) {


		if($_FILES['photo']['type']=='image/jpeg') {
		
		echo 'asdsad';
		
			$tmp_img = $_FILES['photo']['tmp_name'];
			
			$image = imagecreatefromjpeg($tmp_img);
			
			header('Content-Type: image/jpeg');
			
			imagejpeg($image, NULL, 90);
			
			imagedestroy($image);

			
			
		} else {
		echo "Uploaded file was not a JPG image.";
		}
} else {
echo "No photo uploaded!";
}}

else {
echo "
<form action='test.php' method='post'
enctype='multipart/form-data'>
<label for='photo'>User Photo:</label>
	<input type='file' name='photo' />
	<input type='submit' value='Upload a Photo' />
</form>

";} ?>

Comment out this line (add // infront of it)

header('Content-Type: image/jpeg');

Run your code again. Are you getting any errors?

 

Note when using header() no output (echo's, whitespace, text etc) can be sent before using it.

I tried removing the header earlier and it would show some weird characters. I've read somewhere that the header is necessary to remove the weird characters.

 

 

I ran the code on firefox and the message "The image http://localhost/test/test.php cannot be displayed because of errors" appeared.

The characters is the binary of the image. I was aware this was going to happen. If you look closely before the weird characters is there any error messages (to make it clearer you can also comment out imagejpeg() too)?

I converted the imagejpeg() and header lines into comments. 

 

There were no error messages on google chrome and firefox.

 

 

What I've noticed is that the line below would be displayed if you remove the imagejpeg() and header lines, whereas if you include the imagejpeg() and header lines, the line below wouldn't be displayed .I inserted the line below in the code, just to check where it would stop being displayed.

echo 'asdsad';

Doing that will corrupt the image. I only got you to comment out those lines so you can check for errors.

 

Does uncomentting the header/imagejpeg lines and removing the echo before those display the image now?

@Ch0cu3r

 

I removed the header, imagejpeg and echo lines. Chrome and firefox would just display a blank page. 

 

I thought imagejpeg() was necessary to display a jpeg image? 

[Ch0cu3r]

I did not tell you to remove the header/imagejpeg only the echo.

Sorry, I've misread your post. I removed the echo and the problem is still the same.

Your script from 1st post works for me, comment out this line - echo 'asdsad';

@jazzman1 and @Ch0cu3r thanks it's working now.
