PHP - Maintaining Aspect Ratio With Thumbnail
Hey, I want to be able to have a 100x100 thumbnail of pictures I am uploading while cropping the image to maintain the ratio. Right now I am stretching the image and it looks bad but it works. Here is my code...
Quote $new_thumb = "$new_pic"; $sourcefile = "$target2$pic"; $picsize = getimagesize("$target2$pic"); $source_x = $picsize[0]; $source_y = $picsize[1]; $dest_x = 100; $dest_y = 100; $targetfile = "$thumbs$pic"; $pathtofile = pathinfo($sourcefile); $extension = $pathtofile['extension']; $jpegqual = 75; if($extension=='jpg' || $extension=='jpeg' || $extension=='JPG') { $source_id = imagecreatefromjpeg("$target2$pic"); $target_id = imagecreatetruecolor($dest_x, $dest_y); $target_pic = imagecopyresized($target_id,$source_id,0,0,0,0,$dest_x,$dest_y,$source_x,$source_y); imagejpeg($target_id,"$targetfile",$jpegqual); } if($extension=='gif') { $source_id = imagecreatefromgif("$target2$pic"); $target_id = imagecreatetruecolor($dest_x, $dest_y); $target_pic = imagecopyresized($target_id,$source_id,0,0,0,0,$dest_x,$dest_y,$source_x,$source_y); imagegif($target_id,"$targetfile",$jpegqual); } if($extension=='png') { $source_id = imagecreatefrompng("$target2$pic"); $target_id = imagecreatetruecolor($dest_x, $dest_y); $target_pic = imagecopyresized($target_id,$source_id,0,0,0,0,$dest_x,$dest_y,$source_x,$source_y); imagepng($target_id,"$targetfile",$jpegqual); } How could I change this to make the thumbnails maintain the aspect ratio but still be 100x100? Similar TutorialsIs there such a function which allows you pass the image url into a function, it then resizes the image keeping its aspect ratio so that people don't look fat or thin when the picture is in thumbnail form ? Can't see to do it in standard CSS so im wondering if php can some how do it =/ ? Hey, I know how to use the PHP GD functions but how would I resize an image > 1000 width to 1000 width and just resizing the height to w/e needed to keep aspect ratio if the image is set to 1000 width in pixels of course. I don't mess with images much so idk the whole ratio thing. hello again how to get ratio with result max 3 numbers such as 3.00 or 0.11 if im do $mynumbers = 1000 / 400; so reusult to be 1.00 ? and how to put full stop if it is more then 4 numbers result instead of 1000 to have 1.000 If I put into the database this string: Call the wife's son tomorrow How do I put it in to keep that apostrohe (wife's) and then when I retrieve it, also keep it without it displaying as wife/'s If I use stripslashes I think that just gets rid of the slash, but I want to KEEP the slash (but still protecting the database so it is not seen as a quote by the php code). I hope this is clear :-) I can't remember the math to do this, but I use MySQL to calculate an average: 5 = 100% 0 = 0% I want to make a bar that shows an average (like a bar graph) so lets say I get 2.5 as one of my returned results, that means the bar should only be 50% long of the maximum width. Using calculations, how can I get the number 50 (the max width is 100% of a table cell)? $count=0; $numb=50; foreach ($sepkeys as $dbkey) { for ($page=10;$page<=$numb;$page=$page + 10) { // the if block $count=$count+1; } } I am trying to maintain a separate a count for each key number in the above code. Eg: key- 574, it searches from pages 10-50 and increments the count by 1. The problem that I have is the count is continuous. After searching for the first key and moves on to the next key and them I need the count to start from the beginning rather than being continuous. Eg: key-874 : count = 22, in my case the next key 875 : the count is 23 I need to make it 1. I removed the if block and several lines because the code is too long. Can someone please suggest me a way how to do it Hi I am developing a e-commerce website. The user logs in and buy a product when he checkout the page will redirect to the payment gateway. After the payment is completed it will return back to my website. This is ok. But when it is returning back the session maintained in my website get lost. This happen only for the first time. If the user again logged in and checkout the process works good and the session is maintaining. Why does the session lost for first time. I used session_start() in all the pages.. I cannot find the solutions. Kindly help.. Regards P.Balakrishnan I am trying to create a very basic webpage (for local use) that will allow me to add records to a table that I can then come back to at a later date. Essentially, I want a mini spreadsheet in a HTML file. Is this possible? I know that I could do this using PHP, but I just want this for local use, so I do not want / need to upload it anywhere. Plus, I am not linking to any database, I am hoping just to have the table saved into the HTML file. I currently have a JS script that will add rows to my table (with predetermined information - not 100% what I am wanting), but once I close the window, that information is not saved. If anyone could at least point me in the right direction, that would be good (hopefully this all makes sense) Hi, I have managed to get the code below working with a few tweaks here and there. However, you can see that I have written a small function in the file name local.php to allow the user to select "English" or "German" in the link on the test.php page. This works fine but it will only work on that particular webpage. As soon as I move away from that page the locale will return back to "en_US"(English). Is there a way I could implement lets say an option dropdown and save the locale across the whole site. Just in case its relevant I have a MySQL DB available for use if thats appropriate. local.php <?php function english(){ $directory = dirname(__FILE__).'/locale'; $domain = 'messages'; $locale ="en_UK.utf8"; setlocale( LC_MESSAGES, $locale); bindtextdomain($domain, $directory); textdomain($domain); bind_textdomain_codeset($domain, 'UTF-8'); } function german(){ $directory = dirname(__FILE__).'/locale'; $domain = 'messages'; $locale ="de_DE.utf8"; setlocale( LC_MESSAGES, $locale); bindtextdomain($domain, $directory); textdomain($domain); bind_textdomain_codeset($domain, 'UTF-8'); } //Pagination and normal view switch if (isset($_GET['run'])) $linkchoice=$_GET['run']; else $linkchoice=''; switch($linkchoice){ case 'English' : english(); break; case 'German' : german(); break; default : english(); break; } ?> test.php <?php include("local.php"); ?> <html><head></head> <body> <?php echo "<p><a href='?run=English'>English</a> | <a href='?run=German'>German</a> </p>"; ?> <br /> <?php echo gettext("Welcome to My PHP Application"); echo "<br />"; // Or use the alias _() for gettext() echo _("Have a nice day"); ?> </body> </html> Many thanks in advance! This is a LINK to the page -> http://shoutkey.com/carriage I have a problem of separating MySQL concatenated info, yet still maintaining their relationship to other arrays in the same order. First off here is the MySQL code: Code: [Select] $query ="SELECT report,"; $query.="GROUP_CONCAT(DISTINCT docID) AS docIDs, "; $query.="GROUP_CONCAT(DISTINCT analyst) AS analysts, "; $query.="GROUP_CONCAT(DISTINCT region) AS regions, "; $query.="GROUP_CONCAT(DISTINCT country) AS countries, "; $query.="GROUP_CONCAT(DISTINCT topic) AS topics, "; $query.="GROUP_CONCAT(DISTINCT date) AS dates, "; $query.="GROUP_CONCAT(DISTINCT event) AS events, "; $query.="GROUP_CONCAT(DISTINCT link) AS links, "; $query.="GROUP_CONCAT(DISTINCT province) AS provinces "; $query.="FROM reports GROUP BY report ORDER BY dates DESC, docIDs DESC"; The most important thing is to get all attributes about each report. The thing is, each report can have as many records as it must, in order to store various types of information, like, if multiple analysts are working on the report, then each one saves their own record, but when retrieving these records MYSQL concatenates the records, to make it look to the analysts like this Report 1 --- Josh, Rebecca --- Philippines However, my problem is trying to display the reports by country... as you can see http://shoutkey.com/carriage. I have no idea about how to split up the countries, while maintaining their relationship to the $rows pulled from MySQL. I am gonna post the entire code, and let me know if anybody has any ideas. Code: [Select] $result = mysql_query($query); $numrows = mysql_affected_rows(); $current = false; while($row=mysql_fetch_assoc($result)) { $dates = $row['dates']; $analysts = $row['analysts']; $provinces = $row['provinces']; $topics = $row['topics']; $regions = $row['regions']; $countries = $row['countries']; $reports = $row['report']; $links = $row['links']; $events = $row['events']; if (!$current){ //first call echo "<h3><a href=\"#\">{$countries}</a></h3>"; //echo first call $current = $countries; echo "<div>" ;//open content div } elseif($current != $countries){ // country has changed echo "</div>"; //close previous content div echo "<h3><a href=\"#\">{$countries}</a></h3>"; //echo subsequent countries $current = $countries; echo "<div><p>" ;//open content div } echo $analysts." ----- ".$provinces." ----- ".$reports; echo "<br /><br />"; } echo "</div>"; ?> </div> Hi, I have successfully implemented a master details page with the results aligned in columns linking to a details page. I wish to maintain the recordID passed from the master details page and make the dynamic text, which reads Shade A tree that is capable of..... in the attached screen shot a link to another details page referencing the same recordID. The detailspage2.php would look the same as the screenshot except the Shade text and description below will be highlighted, which I can do, there will be a new image and a new image description. All other dynmaic elements on the page will remain the same. I tried to simply save as my detailspage.php to detailspage2.php and create a link to detailspage2.php. It linked to detailspage2.php but none of the record info showed up in their respective table cells. I have all the names desc's, images, etc setup in a table in my database. Please let me know what code and other info you need to help me out with this procedure. Thanks. Hi all, completely new at this and have got myself stuck! I am trying to display a thumbnail image by connecting to my database and retrieving the URL that points to the image. I know that the connection is working but I can't seem to get it to point to the image. Probably something really simple.

Regards, Nortski. hi guys, im trying to resize and save a thumbnail version of images uploaded to my site in a sub folder (thumbs). I've currently got: $image=imagecreatefromjpeg($filepath); list($width, $height) = getimagesize($filepath); $new_width = 200; $new_height= 150; $image_p=imagecreatetruecolor($new_width, $new_height); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height); // Save the image imagejpeg($image_p, '/thumbs'.$filepath); // Free up memory imagedestroy($image_p); but it appears to do nothing, but it also doesn't return any errors? could someone help me out please? thanks! Any one know a tutorial for an easy to use thumbnail script which I can use with pictures stored in mysql database. Is there any way to generate a small image of the 1st page of a pdf document without using a 3rd party like imagemagic. The site is hosted a register.com so I am thinking I am going to be limited to the basic php functions. I want to resize both width and height of the thumb pic this is the php code <?php $id_member=$_SESSION['rid']; if(!empty($foto1_name)) { $nama_file=$foto1_name; $anton->sekur_upload($nama_file); if($valid) { $abpath = "conf/i/"; @copy($foto1, $abpath."/".$foto1_name); $abang_dom=$abpath."/".$foto1_name; list($width, $height) = getimagesize($abang_dom); if($width>200) { make_thumb("$abpath/$foto1_name","conf/i/thumb/$foto1_name",200); } else { $tujuan="conf/i/thumb/".$foto1_name; rename($abang_dom, $tujuan); } } $foto_old_name=$foto1_name; $foto1_name=$id_member."_".$foto1_name; $foto1_name=strtolower($foto1_name); $foto1_name=str_replace(' ', '', $foto1_name); $asal1="conf/i/".$foto_old_name; $asal2="conf/i/thumb/".$foto_old_name; $tujuan1="conf/i/".$foto1_name; $tujuan2="conf/i/thumb/".$foto1_name; rename($asal1, $tujuan1); rename($asal2, $tujuan2); } I want to set the size to 100 x 100, which part of the code that I need to edit? Hi, I have this image gallery slideshow, below the image, it's the thumbnail pics. but the size of the thumbnail pics is random...I want to set the size to be the same for all thumbnail pics, since I'm not the one wrote the code so I'm just guessing that this is the php code for the gallery: Code: [Select] <?php for($i=1;$i<10;$i++) { if(!empty($foto[$i])) { if($i==1) { $foto_first=$foto[$i]; } echo "<img border=0 width=0px height=2px src='conf/i/".$foto[$i]."'>"; $dataku.="'".$foto[$i]."': { thumbnail: 'thumb/".$foto[$i]."'},"; } else { $i--; break; } } $dataku=substr($dataku,0,-1); ?> <link rel="stylesheet" href="css/slideshow.css"> <script src="js/mootools-1.3.1-core.js"></script> <script src="js/mootools-1.3.1.1-more.js"></script> <script src="js/slideshow.js"></script> <script src="js/slideshow.flash.js"></script> <script> window.addEvent('domready', function(){ var data = { <?php echo $dataku;?>}; new Slideshow.Flash('flash', data, { color: ['tomato'],duration: 1500, delay: 10000, height: 400, hu: 'conf/i/', width: 500}); }); </script> <div style="padding-bottom:350px;padding-right:100px"> <div id="flash" class="slideshow"> <img src="conf/i/<?php echo $foto_first; ?>" alt="1" height=100px><br> </div> </div> is this the part that I need to add "size" to it? $dataku.="'".$foto[$i]."': { thumbnail: 'thumb/".$foto[$i]."'},"; I'm totally newb at php, so I have no clue at all I would be needing different picture sizes on different pages on my site but saving different sizes of a single pic is space consuming. I've heard that it's possible to automatically adjust the size of the picture and found a script that ought to make that possible. Unfortunately, it did not work for me.

Quote All it takes is replacing the "src" parameter in the <img> tag with the URL for the PHP script, including the parameters "src" which contains the path to the original image file, and "color" to select the color for the font. The script also supports a "width" parameter to specify the width of your thumbnail image. Using that script to display the above image as a thumbnail by setting the "src" attribute to "makeThumb.php?src=slides/slide1.jpg", we get the resulting image shown on the right. Can anyone please help me with this script or something similar? Thanks in advance. ^_^ Edit: The problem is that the image is not showing. It appears as if it cannot locate the file source. I have a quick question about a script I wrote that searches all .jpg images in a directory (and it's sub-directories) and makes thumbnails of them. The problem I am having is that I am getting an internal server error after about 15 seconds. I have included my script, the class it requires, and my php.ini file that resides in the root of my site. I have searched for a couple of hours online and haven't been able to come up with an answer as to why I am getting that error. The thumbnail file...

I've read the sort, explode, scandir and array manuals - but every attempt fails. I've been reading for days.. and still nothing. I got the script from the net.. While researching how to make this work, I found someone else using the same script needing help on your forums... (http://www.phpfreaks.com/forums/index.php/topic,299137.0.html) I've changed mine a little to work with the directories, and added Javascript for displaying the clicked thumb, in place. The entire thing works like a charm, and displays the generated thumbs and so on - its just that when it comes out on the page, it's in a random order like 2.jpg, 3.jpg, 1.jpg. (It always seems to display the first photo last.) I'd like it to display 1.jpg, 2.jpg, 3.jpg so they appear in order on the page. This way I can group black and white photos from color photos in the same category, or show photos in the order they happened on a vacation for instance. Thanks in advance for any insight! <?php $columns = 5; $thmb_width = 120; $thmb_height = 80; function resizeImage($originalImage,$toWidth,$toHeight){ list($width, $height) = getimagesize($originalImage); $xscale=$width/$toWidth; $yscale=$height/$toHeight; if ($yscale>$xscale){ $new_width = round($width * (1/$yscale)); $new_height = round($height * (1/$yscale)); } else { $new_width = round($width * (1/$xscale)); $new_height = round($height * (1/$xscale)); } $imageResized = imagecreatetruecolor($new_width, $new_height); $imageTmp = imagecreatefromjpeg ($originalImage); imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height); return $imageResized; } function generateThumbnails(){ global $thmb_width,$thmb_height; if ($handle = opendir("/full/path/to/images/galleryname/")) { while ($file = readdir($handle)) { if (is_file($file)){ if (strpos($file,'_th.jpg')){ $isThumb = true; } else { $isThumb = false; } if (!$isThumb) { $dirName = substr($file,0,strpos($file,basename($file))); if (strlen($dirName) < 1) $dirName = '.'; $fileName = basename($file); $fileMain = substr($fileName,0,strrpos($fileName,'.')); $extName = substr($fileName,strrpos($fileName,'.'), strlen($fileName)-strrpos($fileName,'.')); if (($extName == '.jpg') || ($extName == '.jpeg')){ $thmbFile = $dirName.'/'.$fileMain.'_th.jpg'; if (!file_exists($thmbFile)){ imagejpeg(resizeImage($file,$thmb_width,$thmb_height) ,$thmbFile,80); }}}}}}} function getNormalImage($file){ $base = substr($file,0,strrpos($file,'_th.jpg')); if (file_exists($base.'.jpg')) return $base.'.jpg'; elseif (file_exists($base.'.jpeg')) return $base.'.jpeg'; else return ""; } function displayPhotos(){ global $columns; generateThumbnails(); $act = 0; $img_dir = 'images/galleryname/'; if ($handle = opendir($img_dir)) { while ($file = readdir($handle)) { if (strpos($file,'_th.jpg')){ ++$act; if ($act > $columns) { echo '<li><a onclick="return showPic(this)" href="'.getNormalImage($img_dir.$file).'"><img src="'.$img_dir.$file.'" alt="'.$file.'"/></a></li>'; }}}}} ?> <script type="text/javascript" language="javascript"> function showPic (whichpic) { if (document.getElementById) { document.getElementById('placeholder') .src = whichpic.href; if (whichpic.title) { document.getElementById('desc') .childNodes[0].nodeValue = whichpic.title; } else { document.getElementById('desc') .childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue; } return false; } else { return true; } }</script> <div class="galthumbs"><ul> <?php displayPhotos(); ?> </ul></div> <div class="galmain"><img id="placeholder" src="images/galleryname/1.jpg" alt="" /></div><p id="desc"> </p> |
