i have got this code down correctly, i cant see where the problem is, a quick question first, when you getimagesize using php does the file need to be in the temp directory first or can it be on the server prior to a thumbnail being created?
form:
PHP Code:
<?php ## See if it's a first time user $query_user = "SELECT `photo` FROM `users` WHERE `id`='$var_loggedinuserid'"; $results_user = mysql_query($query_user) or die ("Error getting photo 1"); $row = mysql_fetch_array($results_user) or die ("Error getting the photo array"); $photouploaded = $row['photo']; ## HTML form echo ('<br /><div style="border: 1px solid black;padding:10px; background: yellow; color: #000000; font-size: 12px;"><b>Upload your main profile headshot here.</b></div><br />'); echo ("<form action=\"uploadphoto.php\" method=\"post\" enctype=\"multipart/form-data\" />"); echo ("<table class=\"sub_table\" width=\"500\" border=\"1\" align=\"center\" cellpadding=\"5\" cellspacing=\"0\">"); echo ("<tr>"); echo ("<td colspan=\"2\" class=\"edit\" align=\"left\"><img src=\"images/upload_headshot.jpg\"></td>"); echo ("</tr>"); echo ("<tr>"); echo ("<td align=\"center\"><b>Select a photo to upload</b></td><td align=\"center\"><input name=\"usersphoto\" type=\"file\" size=\"50\" /></td>"); echo ("</tr>"); echo ("<tr>"); echo ("<td colspan=\"2\" align=\"right\"><input type=\"submit\" name=\"submit\" value=\"Upload Photo\" /></td>"); echo ("</tr>"); echo ("</table>"); ## HTML form ## Deal with the submission if($_POST['submit']) { $filesize = $_FILES['usersphoto']['size']; $filetype = $_FILES['usersphoto']['type']; $filetemp = $_FILES['usersphoto']['tmp_name']; $filename = $_FILES['usersphoto']['name']; ## vars $maxheight = 500; $maxwidth = 500; $randomnumber = $var_loggedinuser. "-" .time(); ## Allowed file types $allowed_types = array('image/pjpeg','image/gif','image/png','image/jpeg'); if($filesize == 0) { stderr("Upload Failed","No file was uploaded."); include("includes/footer.php"); exit; } if(!in_array($filetype, $allowed_types)) { stderr("Upload Failed","The file you uploaded is not one of the allowed types only .gif and .jpg are allowed."); include("includes/footer.php"); exit; } $imagedimensions = getimagesize($filetemp); $width = $imagedimensions[0]; $height = $imagedimensions[1]; if($width > $maxwidth || $maxheight > 500) { stderr("Upload Failed","Images cannot be larger than $maxwidth x $maxheight, yours was ($width) width and ($height) height, please try again."); include("includes/footer.php"); exit; } ## Rename the file $renamedimage = $randomnumber.".".substr($_FILES["usersphoto"]["name"],strtolower(strlen($_FILES["usersphoto"]["name"]))-3,3); ## Call thumbanil function create_thumbnail($renamedimage); $uploaddirectory = "uploads/".$renamedimage; ## Upload code if(move_uploaded_file($filetemp, $uploaddirectory)) { ## insert the photo in the database $photoquery = mysql_query("UPDATE `users` SET `photo`='$renamedimage' WHERE `id`='$var_loggedinuserid'"); stderr("Upload Successful","Your image has been uploaded successfully."); include("includes/footer.php"); exit; } } ?>
function:
PHP Code:
## Create thumbnail function create_thumbnail($filetemp) { ## Get the original geometry and calculate scales list($width, $height) = getimagesize($filetemp); $xscale = $width/$toWidth; $yscale = $height/$toHeight; ## Recalculate new size with default ratio if ($yscale > $xscale){ $new_width = round($width * (1/$yscale)); $new_height = round($height * (1/$yscale)); } else { $new_width = round($width * (1/$xscale)); $new_height = round($height * (1/$xscale)); } ## Resize the original image $imageResized = imagecreatetruecolor($new_width, $new_height); $imageTmp = imagecreatefromjpeg($filetemp); imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height); return $imageResized; }
ahh darn i'm not sure what happened with the tags there i put them in [php] ones aswell, i have this so far:
PHP Code:
<?php
## See if it's a first time user
$query_user = "SELECT `photo` FROM `users` WHERE `id`='$var_loggedinuserid'";
$results_user = mysql_query($query_user) or die ("Error getting photo 1");
$row = mysql_fetch_array($results_user) or die ("Error getting the photo array");
$photouploaded = $row['photo'];
## HTML form
echo ('<div style="border: 1px solid black;padding:10px; background: yellow; color: #000000; font-size: 12px;"><b>Upload your main profile headshot here.</b></div><br />');
echo ("<form action=\"uploadphoto.php\" method=\"post\" enctype=\"multipart/form-data\" />");
echo ("<table class=\"sub_table\" width=\"500\" border=\"1\" align=\"center\" cellpadding=\"5\" cellspacing=\"0\">");
echo ("<tr>");
echo ("<td colspan=\"2\" class=\"edit\" align=\"left\"><img src=\"images/upload_headshot.jpg\"></td>");
echo ("</tr>");
echo ("<tr>");
echo ("<td align=\"center\"><b>Select a photo to upload</b></td><td align=\"center\"><input name=\"usersphoto\" type=\"file\" size=\"50\" /></td>");
echo ("</tr>");
echo ("<tr>");
echo ("<td colspan=\"2\" align=\"right\"><input type=\"submit\" name=\"submit\" value=\"Upload Photo\" /></td>");
echo ("</tr>");
echo ("</table>");
## HTML form
## Deal with the submission
if($_POST['submit']) {
stderr("Upload Failed","Images cannot be larger than $maxwidth x $maxheight, yours was ($width) width and ($height) height, please try again.");
include("includes/footer.php");
exit;
}
## Rename the file
$renamedimage = $randomnumber.".".substr($_FILES["usersphoto"]["name"],strtolower(strlen($_FILES["usersphoto"]["name"]))-3,3);
///////// Start the thumbnail generation//////////////
$n_width = 300; // Fix the width of the thumb nail images
$n_height = 300; // Fix the height of the thumb nail imaage
$tsrc="thumbs/$renamedimage"; // Path where thumb nail image will be stored
/////////////////////////////////////////////// Starting of GIF thumb nail creation///////////
if (@$userfile_type=="image/gif") {
$im=ImageCreateFromGIF($add);
$width=ImageSx($im); // Original picture width is stored
$height=ImageSy($im); // Original picture height is stored
$newimage=imagecreatetruecolor($n_width,$n_height);
imageCopyResized($newimage,$im,0,0,0,0,$n_width,$n_height,$width,$height);
if (function_exists("imagegif")) {
Header("Content-type: image/gif");
ImageGIF($newimage,$tsrc);
}
elseif (function_exists("imagejpeg")) {
Header("Content-type: image/jpeg");
ImageJPEG($newimage,$tsrc);
}
chmod("$tsrc",0777);
}
////////// end of gif file thumb nail creation//////////////
////////////// starting of JPG thumb nail creation//////////
if($userfile_type == "image/pjpeg"){
$im=ImageCreateFromJPEG($add);
$width=ImageSx($im); // Original picture width is stored
$height=ImageSy($im); // Original picture height is stored
$newimage=imagecreatetruecolor($n_width,$n_height);
imageCopyResized($newimage,$im,0,0,0,0,$n_width,$n_height,$width,$height);
ImageJpeg($newimage,$tsrc);
chmod("$tsrc",0777);
}
//////////////// End of JPG thumb nail creation //////////
#############################################
# Thumbnail
#############################################
include("includes/footer.php");
exit;
}
}
?>
i get the "upload successful" message but still no thumbnail created, can anyone see where i have went wrong at all?
if (@$userfile_type=="image/gif") {
...
if($userfile_type == "image/pjpeg"){
My guess is that your image type is actually 'image/jpeg' and you currently don't have any code that is being executed when it is.
Make sure you have code for each possible type you allow and echo the type of the uploaded file to make sure what it actually is.
