Mam skript, ktery uploadne obrazek + udela se thumbnail.
Uploadne, ale thumbnail se neudela. Chyba: nvalid image dimensions in..+supplied argument is not a valid Image resource radky 63-66 Funkce na vytvoreni thumbnailu pouzivam uz dlouho a fungoval. Nyni se skript nachazi v jinem adresari, ale cestu jsem uz upravil. struktura ../../../../uploads/articles/obrazky_zde.jpg ../../../../uploads/articles/thumbs/thumbs_zde.jpg ../ <?php include("../../../includy/dbz.php"); include("../../../includy/main_funkce.php"); include("../../../includy/config.php"); $error=''; $subfolder =''; // neco/ switch($_POST['from']){ case "gallery": define('_ARTICLE_ATTACH_DIR','../../../../uploads/articles/'); break; case "products": define('_ARTICLE_ATTACH_DIR','../../../../uploads/products/'); break; default: define('_ARTICLE_ATTACH_DIR','../../../../uploads/articles/'); break; } session_start(); //header('Content-Type: text/plain; charset=utf-8'); $funcNum = $_GET['CKEditorFuncNum'] ; $data=UploadImageFile(); $url = str_replace("../../../../","../",$data['file']); $message = $data['warning']; echo "<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction($funcNum, '".$url."', '".$message."');</script>"; function makeThumbz( $pathToImages, $pathToThumbs, $thumbWidth ){ if (!is_dir($pathToThumbs)) { mkdir($pathToThumbs); } //$aa=split("/", $pathToImages); //$poceta=count($aa); //$fname =$aa[$poceta-1]; $fname=basename($pathToImages); $type=strtolower(str_replace(".","",substr($pathToImages,-4))); if ($type=="jpeg" or $type=="jpg"){ $img=imagecreatefromjpeg($pathToImages); } if ($type=="png"){ $img=imagecreatefrompng($pathToImages); } if ($type=="gif"){ $img=imagecreatefromgif($pathToImages); } $width = imagesx( $img ); $height = imagesy( $img ); // calculate thumbnail size $new_width = $thumbWidth; $new_height = floor( $height * ( $thumbWidth / $width ) ); // create a new temporary image $tmp_img = imagecreatetruecolor( $new_width, $new_height ); // copy and resize old image into new image imagecopyresized( $tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height ); $changed_name=str_replace(".","_.",$fname); $final_name=$pathToThumbs.$changed_name; if ($type=="jpeg" or $type=="jpg"){ imagejpeg( $tmp_img, $final_name); } if ($type=="png"){ imagepng( $tmp_img, $final_name); } if ($type=="gif"){ imagegif( $tmp_img, $final_name); } $pix['location']= $pathToImages; $pix['thumb_location']=$pathToThumbs.$fname; return $pix; } function UploadImageFile() { $data['file']=''; $data['warning']=''; if ( strncasecmp($_FILES["upload"]["type"], "image/", 6) == 0 ) { if ($_FILES["upload"]["error"] > 0) { $warning = "Return Code: " . $_FILES["upload"]["error"] ; } else { $file_name = $_FILES["upload"]["name"]; $nname= strtolower(str_replace(" ","_",$file_name)); $new_name = rand(1, 100) . $nname; $move_to_file = _ARTICLE_ATTACH_DIR . $new_name; if (file_exists($move_to_file)) { $warning = $file_name .
