Hey there.
I'm working on a site for someone and I've run into a problem. Anytime I try to open the image to write over it I get errors. Both the folder and the image are chmod 777. I've tried looking online for solutions with no luck. I'm running out of ideas, anyone had this problem before?
Code: Select all
function resizeImage($filename)
{
//Figure out image type
$type = substr($filename, (strlen($filename)-4), strlen($filename));
//1/4 of the image size
if (getimagesize($filename) > 20000)
$percent = 0.25;
else //3/4 of the image size
$percent = 0.75;
// Set a maximum height and width
$width = 120;
$height = 90;
// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);
$ratio_orig = $width_orig/$height_orig;
if ($width/$height > $ratio_orig) {
$width = $height*$ratio_orig;
} else {
$height = $width/$ratio_orig;
}
// Resample
$image_p = imagecreatetruecolor($width, $height);
if ($type == ".jpg" || $type == "jpeg")//jpg image
$image = imagecreatefromjpeg($filename);
else if ($type == ".gif") //gif inage
$image = imagecreatefromgif($filename);
else if ($type == ".png") //png image
$image = imagecreatefrompng($filename);
else
return "Error!";
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
if ($type == ".jpg" || $type == "jpeg")//jpg image
{
imagejpeg($image_p, "uploads/newimage.jpg", 100);
return "<img src=\"uploads/newimage.jpg\" />";
}
else if ($type == ".gif") //gif inage
{
imagegif($image_p, "uploads/newpicture.gif", 100);
return "<img src=\"uploads/newpicture.gif\" />";
}
else if ($type == ".png") //png image
{
imagepng($image_p, "uploads/newpicture.png", 100);
return "<img src=\"uploads/newpicture.png\" />";
}
else
return "Error!";
}[/b]

Warning: imagejpeg() [function.imagejpeg]: Unable to open '
http://graphicart.com/uploads/newimage.jpg ' for writing in /home/stockinv/public_html/graphicart/kernel/functions.php on line 818
Not that the error message helps much....

You don't write or call Jade, what's the deal?
It really says the url?

Lol, I have no clue. No, I took the url out, thats an old error message. Too lazy to refresh the page, after all, that requires clicking...

Have you tried touching it first?
Code: Select all
if ($type == ".jpg" || $type == "jpeg")//jpg image
{
touch("uploads/newimage.jpg");
imagejpeg($image_p, "uploads/newimage.jpg", 100);
return "<img src=\"uploads/newimage.jpg\" />";
}
