Yasoymama Posted August 8, 2012 Share Posted August 8, 2012 I have the same problem, but I can't make it work! I have little knowledge about PHP, so any help would be great for me...

Christian F. Posted August 8, 2012 Share Posted August 8, 2012 First of all I recommend reading up on OOP in PHP 5, as what you have there is a PHP 4 style class. I've taken the liberty of cleaning up the PHP 4 syntax sugar for you, and translating it into PHP 5 style. <?php class imageobject { private $handle; private $type = "png"; private $height = 0; private $width = 0; private $string; // for img height/width tags private $square; private $filesize; // CF: Was missing. // output message public $message; // previous file // var $previous; // CF: Commented out as it was not used. // current private $directory; private $filename; //output private $resample = false; private $quality = "80"; private $output = OUTPUT; // alternatives are png8 or png private $transparent; // only if output=png8 // textobject // var $previewobject; // CF: Commented out as it was not used. // option // var $savefile = true; // CF: Commented out as it was not used. // private $newobj; //constructor public function __construct ($directory, $filename, $width = 0, $height = 0, $color = "FFFFFF") { $this->directory = $directory; $this->filename = $filename; if ($filename == "" && $width > 0 && $height > 0) { $new = $this->createImage ($width, $height); $col = ImageColorAllocate ($new, hexdec (substr ($color, 0, 2)), hexdec (substr ($color, 2, 2)), hexdec (substr ($color, 4, 2))); ImageFilledRectangle ($new, 0, 0, $width, $height, $col); $this->newobj = $this->createUnique ($new); } elseif (file_exists ($directory . $filename)) { $this->filesize = ceil (filesize ($directory . $filename) / 1024); $size = GetImageSize ($directory . $filename); if ($size) $this->handle = $this->getHandle ($directory . $filename, $size[2]); $this->width = $size[0]; $this->height = $size[1]; $this->string = $size[3]; $this->square = $size[0] * $size[1]; if ($this->handle) $this->message = $GLOBALS["message_supported"]; else $this->message = $GLOBALS["message_not_supported"]; } } // constructor // private methods private function getHandle ($name, &$type) { switch ($type) { case 1: $im = imagecreatefromgif ($name); $this->type = "gif"; break; case 2: $im = imagecreatefromjpeg ($name); break; case 3: $im = imagecreatefrompng ($name); $this->type = "png"; break; } return $im; } private function saveAlpha (&$handle) { ImageAlphaBlending ($handle, true); imagesavealpha ($handle, false); imagesavealpha ($handle, true); } private function getHexColor ($xpos, $ypos) { $color = imagecolorat ($this->handle, $xpos, $ypos); $colorrgb = imagecolorsforindex ($this->handle, $color); if ($colorrgb["red"] > 0) $hred = dechex ($colorrgb["red"]); else $hred = "00"; if (strlen ($hred) < 2) $hred = "0" . $hred; if ($colorrgb["green"] > 0) $hgreen = dechex ($colorrgb["green"]); else $hgreen = "00"; if (strlen ($hgreen) < 2) $hgreen = "0" . $hgreen; if ($colorrgb["blue"] > 0) $hblue = dechex ($colorrgb["blue"]); else $hblue = "00"; if (strlen ($hblue) < 2) $hblue = "0" . $hblue; return strtoupper ($hred . $hgreen . $hblue); } private function uniqueName () { $add = ""; $fileparts = split ("\.", $this->filename); $nonchr = array ("__", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"); $desc = str_replace ($nonchr, "", $fileparts[0]); $name = $desc .

Christian F. Posted August 9, 2012 Share Posted August 9, 2012 3.5 hours on an international forum is not a whole lot of time, especially considering that people using this forum come from all over the world. Give it at least 2 days before bumping, as that should give everyone enough time to read, think and respond. That said: The "errors" you've listed are not errors, their notices. Had they been errors, the script would have failed at the first. You should still work to fix them, seeing as they can lead to problems later on. Most of all, because having notices like this is a sign of sloppy coding. If you don't know what the message "undefined variable" means, then I recommend a search for it on the net. It's a fairly straight forward message, with a very logical cause. Quote Link to comment Share on other sites More sharing options...
maxudaskin Posted August 9, 2012 Share Posted August 9, 2012 Since I'm short on time, I'll help you with one of the errors. Take the lead after this, go through your code, and ask yourself where it could go wrong. Notice: Undefined variable: img_dir in xxx/index.php on line 7 7| if (!$img_dir) $img_dir = IMG_DIR; $img_dir was never instantiated. Your code says, "if $img_dir is not true, set it to IMG_DIR." Because $img_dir never existed, the server is says, "Hey! I'm supposed to check this variable, $img_dir, but it doesn't exist." To fix it, ask if it's empty, or isset. if(empty($img_dir) $img_dir = IMG_DIR; You can shorten it into a variable declaration, if you'd like. $img_dir = empty($img_dir) ? IMG_DIR : $img_dir; That last one says, $img_dir equals, if $img_dir is empty, IMG_DIR, otherwise, $img_dir Quote Link to comment Share on other sites More sharing options...

I'm trying to run on my web this application made in PHP: http://allayers.com/mycanvas/ It would be perfect for my site, with some modifications, but as I know there are problems when running under PHP5, although it is supposed to be fixed in the last version. The download page of last version is http://truecolor.allayers.com/, if anyone could make it work on PHP 5... Quote Link to comment Share on other sites More sharing options...
Yasoymama Posted August 10, 2012 Author Share Posted August 10, 2012 The files I included before belong to this application... if anyone can take a look at them... do you think it is possible to make it work or should I forget about it?

PFMaBiSmAd Posted August 11, 2012 Share Posted August 11, 2012 make it work Since you haven't specifically stated exactly what the script is doing that leads you to believe it doesn't work, no one here can help you based on the information you have supplied. If you want specific help with a program, you must supply the specific symptoms or errors that you need help with. You started this thread by adding your post to an existing thread, where you implied that you were getting the same error as in the title - "Cannot re-assign $this". But there is no indication at all that you were getting that error. The list of undefined variable notices 'could' prevent a script from working if that script was trying to use header() statements, sessions, or cookies... But again, nothing you have supplied indicates what is or is not working. We are not here to rewrite poorly written 3rd party scripts for people who want to use them, and since this is a 3rd party script, moving this thread to the appropriate forum section...

Yasoymama Posted August 13, 2012 Author Share Posted August 13, 2012 I am not a PHP expert, so I don't exactly know what the problem with these scripts. I configure the file config. inc. php, and that is suppossed to be the the only one to be customized. The rest of the script are files that don't have to be moddified. When I enter to my index.php page, and I try to load background (the first thing you have to do), the page reloads but no image loads. So the the application stops in that point. This is mycanvas home page: http://allayers.com/mycanvas/ And this is mine one: http://www.yasoymama.com/mycanvas/ As you can see, something is wrong, and I can't solve the problem Quote Link to comment Share on other sites More sharing options...
