GD image manipulation

[garry]

So I'm trying to manipulate some images for my website. I've checked and apparently the GD image library is installed.

 

But when I use the getimagesize(); function, I get the following error:

 

Warning: getimagesize(/dev/albumart/watershed.jpg) [function.getimagesize]: failed to open stream: No such file or directory in /Applications/MAMP/htdocs/dev/test.php on line 23

 

Why does this happen? :/

it means file not found,

does "/dev/albumart/watershed.jpg" exist ?

Hey this is my first post !

 

getimagesize(/dev/albumart/watershed.jpg)

should be

getimagesize(../dev/albumart/watershed.jpg)

if the file exists that is

The file exists, I used an <img src> test to make sure and the image showed up.

 

It's supposed to be /dev/ as i'm using absolute path.

[MadTechie]

lets try something

$filename = "/dev/albumart/watershed.jpg";
if (file_exists($filename))
{
$avar = getimagesize($filename); 
}else{
die("No file");
}

Hmm.. weird...

 

Using this code displays the image:

 

<img src="/dev/albumart/watershed.jpg" />

 

However, using your code, I get an error saying "No file"

Okay turns out it was my fault, I was using the html path for the image instead of the full server path for the php. When I use the full server path the error goes away and the area is just blank. I used var_dump on the variable and got the following array:

 

array(7) { [0]=>  int(300) [1]=>  int(300) [2]=>  int(2) [3]=>  string(24) "width="300" height="300"" ["bits"]=>  int( ["channels"]=>  int(3) ["mime"]=>  string(10) "image/jpeg" }

 

Now how can I use this information to resize the image and such? Sorry for newb question!

[MadTechie]

Okay well the imagesize is working

you can create a php file to resize the image OR use HTML

try something like this

 

$filename = "/dev/albumart/watershed.jpg";
if (file_exists($filename))
{
list($width, $height, $type, $attr) = getimagesize($filename);
//find the larger size
if($height > $width){
$size = "height=\"50px\"";
}else{
$size = "width=\"50px\"";
}
echo "<img src=\"img/flag.jpg\" $size  alt=\"flag\" />";
}else{
echo "<img src=\"img/noflag.jpg\" height=\"50px\" alt=\"missing flag\" />";
}

Thanks very much! That's all I need for now. I'll have a play around with this and see if I can get what I want working but I'm sure i'll run into more troubles later on the track.

 

Thanks a bunch for your help, I really appreciate it
