Help with Advance Image upload & Resizing 1

WilliamMute007 · Sep 10, 2010

Hi All,

I have a script which basically uploades an image to folder (unique folder) each time.

I wanted to extend this script so that when it uploads the image, it should ALSO create a small thumbnail of it so I'll have the original and a small version. I want to store the two images in the same folder with the smaller one simply having "small" or something of that nature appended to the end of the original file name so I can distinguish the two.

The main script works perfectly but I have been having problems for over a day now with the resizing. Please see if you can help... Script below

Code:

<?
include('verify.php');


$title = $_POST['title'];
$text = $_POST['text'];
$categorie = $_POST['categorie'];
$categorie_name = $_POST['categorie_name'];
$author = $_POST['author'];

// Call for the name of categorie
$queryd = "SELECT * FROM $table_d WHERE id_cat=$categorie"; 
$resultd = mysql_query($queryd);
$mycat = @mysql_fetch_object($resultd);
$categorie_name = $mycat->categorie_name;

// LAST INCREMENTATION
$queryz = "SELECT last FROM $table_g"; 
$resultz = mysql_query($queryz);
$incr = @mysql_fetch_object($resultz);
$nrowss = $incr->last;

// NEW ID
$id= $nrowss+1;

umask(0000);
mkdir('../appreciateduploads/'.$id.'', 0777);
	// Folder blog + id of the new article
	$uploadDir = '../appreciateduploads/'.$id.'/';
	
	// Image file data
	$fileName = $_FILES['preview']['name'];
	$tmpName  = $_FILES['preview']['tmp_name'];

    // File extension extraction
	$ext = substr(strrchr($fileName, "."), 1);
	
	// File extension verification
	if ($ext != "jpg" ) { 
		echo ("Only jpg file are accepted (extension .jpg) Thanks !");
		exit;
		}

		
	// Generate random name
	$randName = md5(rand() * time());
	
	// Creation of path
    $filePath = $uploadDir . $fileName;
    $newfilename = $fileName;




list($width,$height)=getimagesize($tmpName, $filePath);
$newwidth=60;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);

$newwidth1=150; //This is where I set the width of the thumbnail
$newheight1=($height/$width)*$newwidth1;
$tmp1=imagecreatetruecolor($newwidth1,$newheight1);

imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,

 $width,$height);

imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1, 

$width,$height);


$filename = "../"$filePath"/". $_FILES['preview']['name'];
$filename1 = "../"$filePath"small". $_FILES['preview']['name'];


//$filename = "upload/". $_FILES['file']['name']; //This is where I decide where to store the original image.  Same size as the thumb
$filename1 = ($tmpName,$filePath ["small"]);
//imagejpeg($tmp,$filename,100);
imagejpeg($tmpName,$filename1,100);
		





    // UPLOAD IMAGE
	// If something wrong.... we stop ! or we upload.
    $result    = move_uploaded_file($tmpName, $filename1, $filePath);
	if (!$result) {
		echo "Error during upload... Please try again or request assistant.";
		exit;
	}







$date_post	=	date("Y-m-d H:i:s");

$insert = mysql_query("INSERT INTO $table_b 
                       (
					   title,
					   text,
					   preview,
					   categorie,

					   author,

if(!$insert) echo alert("Error during insert...");

$update = mysql_query("UPDATE $table_g SET last='$id'");

if(!$update) echo alert("Error during update...");

I appreciate your help in advance please.

Thank you

Code:

list($width,$height)=getimagesize($tmpName, $filePath);

getimagesize() takes only one argument. the $tmpName variable already holds the absolute path to the file.

these lines

Code:

$filename = "../"$filePath"/". $_FILES['preview']['name'];
$filename1 = "../"$filePath"small". $_FILES['preview']['name'];

do not work. you need to use the concatenator (dot) to join strings with variables.

Code:

$filename = "../" . $filePath . "/". $_FILES['preview']['name'];
$filename1 = "../" . $filePath . "small". $_FILES['preview']['name'];

this line does not work

Code:

imagejpeg($tmpName,$filename1,100);

because you are referencing a file uri in the first argument whereas you should be referencing the GD object. I suspect you want $tmp1.

Hi Justin,

Thanks for pointing those out. I implemented your suggestions now I get the following error:

"Warning: mkdir() [function.mkdir]: File exists in /home/fhlinux132/m/mmakers.co.uk/user/htdocs/Template/PHP_/CMS/works_add_process_new.php on line 27

Thanks Justin, I now get this error "There was an error with the upload"

The funny thing also is, I even reversed back to the original code without thumbnail, even that has stopped working too

Don't know what is going on.

WilliamMute007 · Sep 10, 2010

Please ignore my last comment as I spotted the obvious mistake on my side which was the cause. Now am getting an error

"File type is not supported"

Any hope of spotting the cause?

Thanks a bunch!

jpadie · Sep 10, 2010

ok

please add this line

Code:

$type = constant($type);

after the list() lines at lines 55 and 95

WilliamMute007 · Sep 10, 2010

Got this:

error in creating thumbnail

jpadie · Sep 10, 2010

ok. so this means that the uploaded file is not correct for some reason.

substitute this function to get some debug info

Code:

function makeThumbnail($image, $width){
	if (!is_file($image)) return false;
	$info = getimagesize($image);
	print_r($info);
	list($oldwidth, $oldheight, $type) = $info; 
	$suffix = strtolower(image_type_to_extension($type, false));
	$nH = ($width/$oldwidth) * $oldheight;
	
	//get image type and create some variable functions
	$cF = 'imagecreatefrom'.$suffix;
	$sF = 'image'.$suffix;
	$qM = $suffix == 'jpeg' ? 100 : 9;
	
	//instantiate image
	$img = $cF($image);
	
	//instantiate new image
	$nImg = imagecreatetruecolor($width, $height);
	//resize image
	imagecopyresampled($nImg, $img, 0,0,0,0,0,0,$oldWidth, $oldHeight);
	imagedestroy($img);
	$fN = sys_get_temp_dir() . DIRECTORY_SEPARATOR . uniqid('image_'. true) . '.' . $suffix;
	$result = $sF($img, $fN, $qM);
	imagedestroy($nImg);
	return $result ? $fN : false;
}

Here is the Debug info Sir!

you may be using an older version of the GD library that does not support non-integer widths.
i also note that i have misnamed a variable which will definitely have a negative effect

try changing the code as shown

Code:

[red]$height[/red] = [red]intval([/red]($width/$oldwidth) * $oldheight[red])[/red];

Thanks, I now have this error:

Array ( [0] => 1600 [1] => 1200 [2] => 2 [3] => width="1600" height="1200" [bits] => 8 [channels] => 3 [mime] => image/jpeg )

this line

Code:

$result = $sF($img, $fN, $qM);

should be

Code:

$result = $sF($[red]nI[/red]mg, $fN, $qM);

really sorry about this. sloppy work. too fast and too many balls in the air.
