Image Resource Mixup…

[thure]

Hi there,

 

I'm basically trying to crop and resize images received from $_FILES in a form. The errors I've been getting this entire evening have been these:

 

Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /home/willshow/public_html/queermcgill/admincaledit2.php on line 108

 

Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/willshow/public_html/queermcgill/admincaledit2.php on line 109

 

The two lines it's referring to are the two commands at the end of this source code:

//POSTERLINK
if(isset($_FILES['fposterlink'])){
$curwidth=1;
$curheight=1;
$posterlink="";
$uploaddir = '/uploaddir/eventimg/';
$ext=strtolower(file_extension($_FILES['fposterlink']['name']));
$uploadtemppath = $_FILES['fposterlink']['tmp_name'];
$posterlink = $uploaddir.$keyid."posterlink.".$ext;

$cursize=getimagesize($uploadtemppath);
$curwidth =$cursize[0];
$curheight=$cursize[1];

$imgrsc=imagecreate(174,261);
$tmprsc=imagecreate(1,1);

$cropx = 0;
$cropy = 0;
$cropw=$curwidth;
$croph=$curheight;
$ratio=(2/3);

if(($curwidth/$curheight)!=$ratio){
if($curwidth > $ratio*$curheight){//too wide
$cropx = ($curwidth-($ratio*$curheight))/2;
$cropyw = $ratio*$curheight;
}
if($curwidth < $ratio*$curheight){//too tall
$cropy = ($curheight-($curwidth/$ratio))/2;
$croph = $curwidth/$ratio;
}
}//end IF not within ratio

switch($ext){
case "jpg":
$tmprsc=imagecreatefromjpeg($uploadtemppath);
break;
case "jpeg":
$tmprsc=imagecreatefromjpeg($uploadtemppath);
break;
case "gif":
$tmprsc=imagecreatefromgif($uploadtemppath);
break;
case "png":
$tmprsc=imagecreatefrompng($uploadtemppath);
break;
}

imagecopyresampled('$imgrsc','$tmprsc',0,0,$cropx,$cropy,174,261,$cropw,$croph);
imagejpeg($imgsrc,$posterlink,80);

}//end check for POSTERLINK upload
//END POSTERLINK

 

Am I missing something? I tried my best before posting on a forum – I almost never hit a dead end like this, but now I'm utterly clueless.

 

Thanks very much and best wishes,

do not place $imgsrc in quotes in imagecopyresampled

Okay, that was dumb on my part - I've just fixed it.

 

I get this error now:

 

Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/willshow/public_html/queermcgill/admincaledit2.php on line 108

 

which is great because it's one less!

 

here is the new source code which produces the error:

if(isset($_FILES['fposterlink'])){
$curwidth=1;
$curheight=1;
$posterlink="";
$uploaddir = '/uploaddir/eventimg/';
$ext=strtolower(file_extension($_FILES['fposterlink']['name']));
$uploadtemppath = $_FILES['fposterlink']['tmp_name'];
$posterlink = $uploaddir.$keyid."posterlink.".$ext;

$cursize=getimagesize($uploadtemppath);
$curwidth =$cursize[0];
$curheight=$cursize[1];

$imgrsc=imagecreate(174,261);
$tmprsc=imagecreate(1,1);

$cropx = 0;
$cropy = 0;
$cropw=$curwidth;
$croph=$curheight;
$ratio=(2/3);

if(($curwidth/$curheight)!=$ratio){
if($curwidth > $ratio*$curheight){//too wide
$cropx = ($curwidth-($ratio*$curheight))/2;
$cropyw = $ratio*$curheight;
}
if($curwidth < $ratio*$curheight){//too tall
$cropy = ($curheight-($curwidth/$ratio))/2;
$croph = $curwidth/$ratio;
}
}//end IF not within ratio

switch($ext){
case "jpg":
$tmprsc=imagecreatefromjpeg($uploadtemppath);
break;
case "jpeg":
$tmprsc=imagecreatefromjpeg($uploadtemppath);
break;
case "gif":
$tmprsc=imagecreatefromgif($uploadtemppath);
break;
case "png":
$tmprsc=imagecreatefrompng($uploadtemppath);
break;
}

imagecopyresampled($imgrsc,$tmprsc,0,0,$cropx,$cropy,174,261,$cropw,$croph);
imagejpeg($imgsrc,$posterlink,80);

}

 

does imagecopyresampled not modify the resource $imgrsc, which is already existing?

[thure]

oh jeez, clerical error!

 

I misspelled $imgrsc $imgsrc because I'm so used to typing 'src.'

 

problem solved! thanks so much!
