GioG7 Posted February 8, 2011 Share Posted February 8, 2011 I'm using some code for an image gallery and everything works fine except the thumbnails created form the original images. Maybe someone can help me find out what I am doing wrong. I am sort of new to PHP so please bare with me please. Here is the code I am using... http://www.webmastertalkforums.com/php-tutorials/80-php-gallery.html Keep in mind I replaced every "http://forum.codecall.net/images/" with "pictures" to be able to move and upload the images locally. Here is what my code looks like... index.php include("../start_session.php"); // Let's start our class class album{ // Form for creating a new album function create_new_album_form(){ echo "<b>Create new album</b><br /><br />"; echo "<form action='index.php?act=new&do=create' method='post'>"; echo "Album name:<br /><input type='text' name='album_name' /><br /><input type='submit' value='Create' />"; echo "</form>"; } // Here we create a new album function create_new_album(){ // Albums new name $album_name = addslashes(htmlentities(htmlspecialchars($_REQUEST['album_name']))); // If there's nothing entered, display an error if($album_name == ""){ die("Please enter your album's name!"); } $sql = "SELECT * FROM album WHERE name='".mysql_real_escape_string($album_name)."'"; $query = mysql_query($sql); // Check is there any albums already named like this if(mysql_num_rows($query)>0){ // If this name is already in use, display an error die("This name is already in use! Please choose another name."); }else{ // If this name is not in use, add it to database $sql = "INSERT INTO album (name) VALUES ('".$album_name."')"; $query = mysql_query($sql); if(!$query){ die("Can not create a new album: <b><i>".mysql_error()."</i></b>"); }else{ $sql = "SELECT * FROM album WHERE name='".mysql_real_escape_string($album_name)."'"; $query = mysql_query($sql); if(!$query){ die(mysql_error()); }else{ $row = mysql_fetch_array($query); $album_id = $row['id']; } // If album was successfully created, display message echo "Album created! <a href='index.php?act=view&id=".$album_id."'>View</a>"; } } } // Form for uploading your file function upload_image_form(){ // Let's create a unique name for your image $date = date("YmdHis"); $micro = explode(".", microtime(true)); $uniname = $date."".$micro['1']; $album_id = addslashes(htmlentities(htmlspecialchars($_REQUEST['id']))); // If album's id is wrong, display an error if(!is_numeric($album_id)){ die("Wrong album ID!"); }else{ // Display file uploading form echo "Upload new image<br /><br />"; echo "<i>You can upload: JPG, GIF and PNG images.</i><br />"; echo "<form enctype='multipart/form-data' action='index.php?act=upload&do=add&id=".$album_id."' method='post'>"; echo "Select file: <br />"; echo "<input type='file' name='file' /><br />"; echo "<input type='hidden' name='new_name' value='".$uniname."' />"; echo "<input type='submit' value='Upload' />"; echo "</form>"; } } // This function uploads your image function upload_image(){ // Let's get all info that we need for uploading our image $file_name = $_FILES['file']['name']; $file_size = $_FILES['file']['size']; $file_type = $_FILES['file']['type']; $file_tmp = $_FILES['file']['tmp_name']; $max_size = "512000"; # You can change this number. at the moment max file size is 500kb # $file_ext_exp = explode(".", $file_name); $file_ext = $file_ext_exp['1']; $uni = addslashes(htmlentities(htmlspecialchars($_REQUEST['new_name']))); $new_name = $uni.".".$file_ext; $date = date("Y-m-d H:i:s"); $album_id = addslashes(htmlentities(htmlspecialchars($_REQUEST['id']))); // If a file wasn't selected, display an error if($file_name == ""){ die("Please select a picture!"); }else{ // Let's specify what image types we allow to upload $types = array("image/jpg", "image/jpeg", "image/gif" , "image/png"); // If an user uploads different type of image, display an error if(!in_array($file_type, $types)){ die("You can not upload this type of files! <a href='javascript:history.go(-1);'>Go back!</a>"); }else{ // If type is OK but image size is too big, display an error if($file_size>$max_size){ die("Your image is too big!

micmania1 Posted February 8, 2011 Share Posted February 8, 2011 Are you getting any error messages? Are you running on a shared server? Try creating a php page as so: <?php phpinfo(); ?> Check to see if you have GD extensions enabled. Quote Link to comment Share on other sites More sharing options...
GioG7 Posted February 8, 2011 Author Share Posted February 8, 2011 I don't get any errors when running the index.php. However when I access the thumb.php (...gallery/thumb.php?act=view&id=3) I get the following errors: Warning: getimagesize(pictures) [function.getimagesize]: failed to open stream: No such file or directory in /home/giog7/giovannyjimenez.com/NEWcheeburger/gallery/thumb.php on line 62 Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions in /home/giog7/giovannyjimenez.com/NEWcheeburger/gallery/thumb.php on line 66 Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /home/giog7/giovannyjimenez.com/NEWcheeburger/gallery/thumb.php on line 82 I am not sure if the server is shared or not and if gd extensions was something I had to manually install or enable myself I definitely don't have that.

BlueSkyIS Posted February 8, 2011 Share Posted February 8, 2011 $file needs to be the full path of the file on the server. Quote Link to comment Share on other sites More sharing options...
GioG7 Posted February 9, 2011 Author Share Posted February 9, 2011 On both files? And direct path of where you want to save the images and/or location of the images? I first though that's what I was supposed to do but it gave me a few errors. Quote Link to comment Share on other sites More sharing options...
