spires Posted September 5, 2008 Share Posted September 5, 2008 Hi Guys I'm working on a image upload and resize script. So far I can upload jpg files, resize them and place the resized jpg file into a thumbnails folder. However, if I try to upload a PNG file, the image uploads but wont resize. Can anyone help? Example: http://reviews4mobilephones.com/test.php Code: <?PHP if (isset($_POST['submit'])){ if ($_FILES['image']['name']==''){ }else{ $random_digit=rand(00000000,99999999); $width = 200; // size of width $filedir = 'images/test/orig/'; // the directory for the original image $thumbdir = 'images/test/thumb/'; // the directory for the thumbnail image $largedir = 'images/test/large/'; // the directory for the large image $prefix = ''; // the prefix to be added to the original name $maxfile = '1000000'; // max file size $mode = octdec('0666'); // octdec -- Octal to decimal. // The mode parameter consists of three octal number components specifying access restrictions for the owner, // the user group in which the owner is in, and to everybody else in this order. e.g (666) $userfile_name = $_FILES['image']['name']; $userfile_tmp = $_FILES['image']['tmp_name']; $userfile_size = $_FILES['image']['size']; $userfile_type = $_FILES['image']['type']; $userfile_error = $_FILES['image']['error']; $imgsize = @getimagesize($userfile_tmp); // sticks in the image size into the array ($imgsize) $origwidth = $imgsize[0]; // = image width $origheight = $imgsize[1]; // = image height $ratio = ($origheight/$origwidth); // $height = ($width * $ratio); $flag = 0; if(strcmp($userfile_type, "image/jpeg")==0){ $type='jpg'; $flag = 1; }elseif (strcmp($userfile_type, "image/pjpeg")==0){ $type='jpg'; $flag = 1; } if(strcmp($userfile_type, "application/x-shockwave-flash")==0){ $new_img_name = $random_digit.".swf"; $type='swf'; $flag = 2; } if(strcmp($userfile_type, "image/gif")==0){ $new_img_name = $random_digit.".gif"; $type='gif'; $flag = 3; } if(strcmp($userfile_type, "image/png")==0){ $type='png'; $flag = 4; } $new_img_name = $random_digit.'.'.$type; if($type == 0){ $wrong_type = "<span class='pro_guide_text'>wrong file type.<br> You can upload .jpg, .png, .gif and .swf files only.</span>"; } // $prod_img = the image folder and the image and name $prod_img = $filedir.$new_img_name; $prod_img_thumb = $thumbdir.$new_img_name; //move_uploaded_file -- Moves an uploaded file to a new location. //move the uploaded file to the image folder with a tempory name. if(move_uploaded_file($userfile_tmp, $prod_img)){ $moved = "Thank You, Your File Has Been Uploaded"; } else{ $moved = "Sorry, Your File Failed To Upload"; } echo $prod_img; // chmod -- Changes file mode, // set the user interface for the image chmod ($prod_img, $mode); // getimagesize -- Get the size of an image // find the size of the original image $sizes = getimagesize($prod_img); $new_height = $height; $new_width = $width; // $new_width = abs($new_height/$aspect_ratio); // this code will only change the height, and make the width in ratio $destimg=ImageCreateTrueColor($new_width,$new_height) or die('Problem In Creating image'); $srcimg=ImageCreateFromJPEG($prod_img) or die('Problem In opening Source Image'); ImageCopyResized($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg)) or die('Problem In resizing'); ImageCopyResampled($destimg, $srcimg, 0, 0, 0, 0, $new_width, $new_height, $sizes[0], $sizes[1]) or die('Problem In resampling'); ImageJPEG($destimg, $prod_img_thumb,90) or die('Problem In saving'); imagedestroy($destimg); } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <title>Untitled Document</title> <script language="JavaScript" type="text/JavaScript"> <!-- function MM_jumpMenu(targ,selObj,restore){ //v3.0 eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'"); if (restore) selObj.selectedIndex=0; } function MM_openBrWindow(theURL,winName,features) { //v2.0 window.open(theURL,winName,features); } //--> </script> </head> <body> <form action="<?PHP $_SERVER['PHP_SELF']; ?>" method="post" name="form1" enctype="multipart/form-data"> <table width="480" border="0" cellspacing="1" cellpadding="0"> <tr> <td colspan="4"><br>Image: <input type="file" name="image"></td> </tr> <tr> <td colspan="4" height="30"> <input name="submit" type="submit" value="submit" /> </td> </tr> </table> </form> <?PHP /* echo ' <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="491" height="73"> <param name="movie" value="images/test/orig/53959737.swf"> <param name="quality" value="high"> <embed src="images/test/orig/53959737.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="491" height="73"></embed> </object><br><br>*/ ?> </body> </html> Link to comment https://forums.phpfreaks.com/topic/122881-png-files-help/ Share on other sites More sharing options...
thebadbad Posted September 5, 2008 Share Posted September 5, 2008 The functions imagecreatefromjpeg() and imagejpeg() are, as the names suggest, JPEG specific functions. Similar PNG functions are - yes, you guessed it - imagecreatefrompng() and imagepng() Link to comment https://forums.phpfreaks.com/topic/122881-png-files-help/#findComment-634769 Share on other sites More sharing options...
