PHP - Uploaded Images - Database Or Files?
Is it better to store uploaded images as 'content' in the database? (like he http://www.techsupportforum.com/forums/f49/tutorial-upload-files-to-database-176804.html).. Or just as a regular file which is referenced in the database..?
Similar TutorialsAt the moment I have been uploading files to my server using <input type='files'> and binary encrytion. I would like to have more controll over the files tmp_name. is there a way to assing it befor hand? Hi All, I'm trying to validate file types and keep seeing an error. I only allow .gif, .jpg or .png. However, if I upload any of those file types, I get an error message.... If I echo out $filetypeCheck, I get image/png, which is corrent... Code: [Select] $filetypeCheck = $_FILES["file"]["type"]; if( ($filetypeCheck != "image/gif") || ($filetypeCheck != "image/jpeg") || ($filetypeCheck != "image/png") ) { $val_error[] = 'File Type Error! (.gif, .jpg and .png only)'; } Whats going on here? Hello I am using the code:
<?php hi everyone i am currently making my website with an uploadform. The upload function is working, but now i am trying to make the site remember the last 5 uploads. The filenames should appear in an array: $aotf[0] $aotf[1] $aotf[2] $aotf[3] $aotf[4] and since all files that can be/are uploaded are images, i want them to be drawed next to each other, each 128x128. THAT is working, but the fetch for images doesn't. When an image is uploaded, i execute this code: $readhandle=fopen("uploaddb.log","r"); $aotf=fread($handle,filesize("uploaddb.log")); fclose($readhandle); $writehandle=fopen("uploaddb.log","w"); fwrite($writehandle,"$aotf\r\n" . "uploadform/gebruikers/" . $naam); fclose($writehandle); then,there is some html code, and then there is this code: $aotf=explode("/n",$aotf); for($i = count($aotf) - 5; $i <= count($aotf); $i++) { echo ' <img src="'. $aotf[$i] . '" width="128" height="128"> '; } when i open the page, all img src's are empty. The writing works, and the folder of the image is 7777 chmod and the images draw on the screen, but not as the last uploaded. Does anyone know how to make this work? maybe even without a fwrite? Thank you, masterens EDIT: i cannot use mysql i am trying to create a small script that will let you

Hi, I have a question. Can I actually use windows hosting on .php files, or .php files are only suitable to linux domain? Currently I am practicing some php files in the windows domain and I have received a message stated 'no database selected'. However I have definitely created the database, are there any other reasons which may cause this problem? Thanks <?php echo '<select name="race" id="race"> <option value="">--Please select one--</option>'; $dbc = mysql_connect(111', '111', '111', '111') or die(mysql_error()); $query = ("SELECT * FROM race ORDER BY race_id ASC"); $sql = mysql_query($query, $dbc) or die(mysql_error()); while($data = mysql_fetch_array($sql)) { echo'<option value="'.$data['race_id'].'">'.$data['race_name'].'</option>'; } echo '</select><br/>'; mysql_close($dbc); ?> Hi Basically I've built a CMS where by my clients can upload a number of images. On the success page I want to display the images they uploaded by file name. The issue is the number of images can vary. They may upload 2 or 10 or 50 etc. So far I've come up with this: Code: [Select] // number of files $UN = 3; //I've set this to 3 for now, but this is passed from the upload page! // server directories and directory names $dir = '../properties'; $images = glob($dir.'/*.{jpg}', GLOB_BRACE); //formats to look for $num_of_files = $UN; //number of images to display from number of uploaded files foreach($images as $image) { $num_of_files--; $newest_mtime = 0; $image = 'BROKEN'; if ($handle = @opendir($dir)) { while (false !== ($file = readdir($handle))) { if (($file != '.') && ($file != '..')) { $mtime = filemtime("$dir/$file"); if ($mtime > $newest_mtime) { $newest_mtime = $mtime; $image = "$file"; } } } } if($num_of_files > -1) //this made me laugh when I wrote it echo $trimmed = ltrim($image, "../properties").'<br />'; //display images else break; } Without this piece of code: Code: [Select] $newest_mtime = 0; $image = 'BROKEN'; if ($handle = @opendir($dir)) { while (false !== ($file = readdir($handle))) { if (($file != '.') && ($file != '..')) { $mtime = filemtime("$dir/$file"); if ($mtime > $newest_mtime) { $newest_mtime = $mtime; $image = "$file"; } } } } It shows the first 3 files alphabetically. I want to view the last number of images added. With the above code it simply shows the last image added 3 times! So I need to get the time each image was added and then order by the newest added and limit to the number of images uploaded. Any suggestions please? Kindest regards Glynn Hi all, Im trying to move files that im uploading from my main domain to a sub domain. I think I can achieve this using passthru? Im having issues with this, can any one point me in the right direction please? Thanks, Phil Hi, I have limited experience of using PHP, but having done some searching around it would seem that it is possible to convert audio files that are uploaded through a web page to mp3 using ffmpeg. The audio files would be uploaded using the Uploadify script to subfolders that are named according to the user's login. I would need the PHP script to be able to process all audio files that are either not in MP3 format, or are in MP3 format but greater than 192kbps, deleting the original file after the conversion. Am I right in thinking that this could be achieved using PHP, and if so, can anyone get me started with some code, or a link to a webpage with some code? Also, I am currently using Hostpapa for hosting my website, and I understand that they don't include ffmpeg, and also don't allow ssh. I read on one website that I could still install a compiled version of ffmpeg on a shared server, but I am not sure if this means that it would work on Hostpapa, or whether I would need to change my host to get ffmpeg working. Any advice on any of this would be welcome! Thanks, Nick show list of files uploaded by current session user to the database. I want to show different users when they log in to the website...they can see a list of old files that they have uploaded. can anyone tell me the code/script to this.....please, ty Hi everyone!! I have looked into how the upload script works and this is what i have: Code: [Select] <?php if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000)) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />"; if (file_exists("upload/" . $_FILES["file"]["name"])) { echo $_FILES["file"]["name"] . " already exists. "; } else { move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; } } } else { echo "Invalid file"; } ?> Which is un-tested at the moment, but let's just say for talking sake it worked 100% what elements of this script would i be looking at to display the files uploaded on to another page, in my case my homepage? ive found as to yet, that the uploads have to be stored on a file somewhere on my server, which i've set up. But i thought it would be just as easy to have a field in my table named upload and display it within the table next to the other results? instead i just get whatever the file name is named.jpg. Any help in looking towards the answer? many thanks in advance guys! Hi everyone, I am after a scrpit/function that will get information of an uploaded image, resize it, then display the manipulated image. in my "upload" script, there will be a size limit and a file extension/type limit to: 600 x 200px / jpg, gif, jpeg... this is to keep the script i'm after more simple. As using vector images i'm told is such a complicated problem for me at this time. So... to get the size info/dimensions its like this: Code: [Select] <?php list($width, $height, $type, $attr) = getimagesize("image_name.jpg"); echo "Image width " .$width; echo "<BR>"; echo "Image height " .$height; echo "<BR>"; echo "Image type " .$type; echo "<BR>"; echo "Attribute " .$attr; ?> and..... resize something like this: Code: [Select] function get_image_sizes($sourceImageFilePath, $maxResizeWidth, $maxResizeHeight) { // Get width and height of original image $size = getimagesize($sourceImageFilePath); if($size === FALSE) return FALSE; // Error $origWidth = $size[0]; $origHeight = $size[1]; // Change dimensions to fit maximum width and height $resizedWidth = $origWidth; $resizedHeight = $origHeight; if($resizedWidth > $maxResizeWidth) { $aspectRatio = $maxResizeWidth / $resizedWidth; $resizedWidth = round($aspectRatio * $resizedWidth); $resizedHeight = round($aspectRatio * $resizedHeight); } if($resizedHeight > $maxResizeHeight) { $aspectRatio = $maxResizeHeight / $resizedHeight; $resizedWidth = round($aspectRatio * $resizedWidth); $resizedHeight = round($aspectRatio * $resizedHeight); } // Return an array with the original and resized dimensions return array($origWidth, $origHeight, $resizedWidth, $resizedHeight); } // Get dimensions $sizes = get_image_sizes($sourceImageFilePath, $maxResizeWidth, $maxResizeHeight); $origWidth = $sizes[0]; $origHeight = $sizes[1]; $resizedWidth = $sizes[2]; $resizedHeight = $sizes[3]; // Create the resized image $imageOutput = imagecreatetruecolor($resizedWidth, $resizedHeight); if($imageOutput === FALSE) return FALSE; // Error condition // Load the source image $imageSource = imagecreatefromjpeg($sourceImageFilePath); if($imageSource === FALSE) return FALSE; // Error condition $result = imagecopyresampled($imageOutput, $imageSource, 0, 0, 0, 0, $resizedWidth, $resizedHeight, $origWidth, $origHeight); if($result === FALSE) return false; // Error condition // Write out the JPEG file with the highest quality value $result = imagejpeg($imageOutput, $outputPath, 100); if($result === FALSE) return false; // Error condition And.... display is this: Code: [Select] <?php $database="***"; mysql_connect ("***", "***", "***"); @mysql_select_db($database) or die( "Unable to select database"); $result = mysql_query( "SELECT company_name, location, postcode, basicpackage_description, premiumuser_description, upload FROM Companies" ) or die("SELECT Error: ".mysql_error()); $num_rows = mysql_num_rows($result); print "\n\n\nThere are $num_rows records.<P>"; echo "<table><tr><th>Comppany Name</th><th>Location</th><th>Postcode</th><th>Basic Members</th><th>Upgraded Users</th><th>Company Logo</th></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td></tr>";// store the records into $row array and loop through while ( $row = mysql_fetch_array( $result, MYSQL_ASSOC ) ) { // Print out the contents of the entry echo "<tr><td>{$row['company_name']}</td>"; echo "<td>{$row['location']}</td>"; echo "<td>{$row['postcode']}</td>"; echo "<td>{$row['basicpackage_description']}</td>"; echo "<td>{$row['premiumuser_description']}</td>"; echo "<td><img src=\"http://www.removalspace.com/images/COMPANIES{$row['upload']}\" alt=\"logo\" /></td></tr>";} echo "</table>"; ?> How will all these fit together in one script? any help i'd love it! many thanks in advance Hi Everyone, I've been studying the topics at this site and others on ways to count uploaded images; and what I've tried hasn't worked. I have seen this question posed and answered many times and most of the answers are something akin to this: Code: [Select] $count = count($_FILES['userfile'] ['name']); echo "the number of photos is ".$count; The explanation usually states that "count($_FILES['userfile'])" will simply count the number of elements in the array and return 5. But including ['name'] will return the number of files (images) uploaded. I will allow up to five photos to be uploaded (less is OK too) and want to count them in order to iterate through the proper number of loops to filter and process the photos. I've tested both of the above and get 5 (elements) when I count the ['userfile']; but get 0 (zero) when I test "['userfile'] ['name']". Here's the html code: Code: [Select] <!-- html here to input form data --> <label></label><input type="hidden" name="MAX_FILE_SIZE" value="500000000" /><br /> <label for="userfile">Upload photo 1</label> <input type="file" name="userfile1" id="userfile1" /><br /> <label for="userfile">Upload photo 2</label> <input type="file" name="userfile2" id="userfile2" /><br /> <label for="userfile">Upload photo 3</label> <input type="file" name="userfile3" id="userfile3" /><br /> <label for="userfile">Upload photo 4</label> <input type="file" name="userfile4" id="userfile4" /><br /> <label for="userfile">Upload photo 5</label> <input type="file" name="userfile5" id="userfile5" /><br /><br /> <label></label><input type="submit" name="userfile" value="Send Ad" /> </form> I've been testing the uploads with two files (jpg) and have tried to come up with an alternative that can iterate through the file arrays and determine how many photos I have. The code I've been testing is as follows: Code: [Select] $num = 1; $count = 0; while ($num <=5) { foreach ($_FILES['userfile'.$num] as $upload){ if ($upload ['error'] != 4){ } $count ++; } $num++; } echo "the number of photos is ".$count; I'm using "['error'] !=4" because some times people won't have 5 photos to upload. The result I get is 25 or 5 (files) x 5 (elements) for a total of 25. Does anyone know the proper way of doing this? Thanks for you input!

Hi all I haven't used php for a while now and I'm really stuck on some code I wrote and now I can't work how to change it. I have this function to upload images and create thumbnails. The thumbnails can be either landscape or portrait and I want them to have the same height. At the moment the portrait thumbnails height is equal to the landscape thumbnail width. The dimensions of the thumbnails are the same but the portrait images are portrait. How can I size the thumbnails so they all have the same height. Thanks in advance for any help or advice on this.

"thumbs/"; $photo_id_arr = array(); $photo_ext_arr = array(); $photo_id_ext_arr = array(); // if(isset($_FILES['images'])){ $image_uploaded = $_FILES['images']; for($i=0; $i<=count($_FILES['images']['name']);$i++){ if(!empty($image_uploaded['name'][$i])){ if(array_key_exists($image_uploaded['type'][$i], $photo_types)){ $file_temp = mysql_prep($image_uploaded['name'][$i]); // $query = "INSERT INTO photos (filename) VALUES ('{$file_temp}')"; $result = mysql_query($query); confirm_query($result); if($result){ $photo_id = mysql_insert_id(); array_push($photo_id_arr, $photo_id); } // $filetype = $image_uploaded['type'][$i]; $ext = $photo_types[$filetype]; array_push($photo_ext_arr, $ext); $dbfile_name = $photo_id . $ext; // $query = "UPDATE photos SET filename = '{$dbfile_name}' WHERE photo_id = '{$photo_id}'"; $result = mysql_query($query); confirm_query($result); // // $stored_image = $image_Dir . $dbfile_name; $stored_thumb = $image_thumb_Dir . $dbfile_name; move_uploaded_file($image_uploaded['tmp_name'][$i], $stored_image ); // $src_image = imagecreatefromjpeg($stored_image); // $src_width = imagesx($src_image); $src_height = imagesy($src_image); $new_width = 900; $new_height = 900; // if($src_width > $src_height){ $img_w = $new_width; $img_h = $src_height*($new_height/$src_width); } if($src_width < $src_height){ $img_w = $src_width*($new_width/$src_height); $img_h = $new_height; } if($src_width == $src_height){ $img_w = $new_width; $img_h = $new_height; } // $mainImg = imagecreatetruecolor($img_w, $img_h); imagecopyresampled($mainImg, $src_image,0,0,0,0,$img_w, $img_h, $src_width, $src_height); imagejpeg($mainImg, $stored_image, 100); imagedestroy($src_image); imagedestroy($mainImg); //*************************** // // // //*************************** $src_image = imagecreatefromjpeg($stored_image); // $src_width = imagesx($src_image); $src_height = imagesy($src_image); $new_width = 85; $new_height = 85; // if($src_width > $src_height){ $thumb_w = $new_width; $thumb_h = $src_height*($new_height/$src_width); } if($src_width < $src_height){ $thumb_w = $src_width*($new_width/$src_height); $thumb_h = $new_height; } if($src_width == $src_height){ $thumb_w = $new_width; $thumb_h = $new_height; } // $thumb = imagecreatetruecolor($thumb_w, $thumb_h); imagecopyresampled($thumb, $src_image,0,0,0,0,$thumb_w, $thumb_h, $src_width, $src_height); imagejpeg($thumb, $stored_thumb, 100); imagedestroy($src_image); imagedestroy($thumb); }else{ //echo "File format not supported."; } } } array_push($photo_id_ext_arr, $photo_id_arr); array_push($photo_id_ext_arr, $photo_ext_arr); return $photo_id_ext_arr; } } Right now users log in and upload an image to the website. I want every image that is uploaded to be watermarked with a particular logo. Is this possible? Any hints or tips will be appreciated. Thank you. |
