PHP - Imagecreatefromjpeg - Need Some Info
Hi guys
I need some info Am doing an upload page for pictures, that crops images to two different sizes which works fine with small images. However some larger images it doesn't work (locally it works but not on the my server provider). I can upload the file (3481 * 2346 at 300 dpi) no problem but it actually never executes the imagecreatefromjpeg($myUploadedFile). Is there any issues with large file. I've been doing some recherches but can't seem to find any answer. The obvious idea is to have people upload photos without asking them to resize them. Thanks Similar TutorialsAfter working with the sample imagecreatefromjpeg provided in the PHP manual, I successfully got a result (after clearing my cache) from Quoteimagecreatefromjpeg($im, $file); I've gotten a good education after navigating this function over the past week, and loaded it with ECHO messages to give me insight. Everything was going fine. And then, this ONE test image came along. Apparently, the image (which is as good aj peg as I can find) FAILS the if(!im) test. When I used echo $im; i discovered that when images pass through the function, they receive a "Resource" name. Images that FAIL are NOT named. This image gets a Resource name, yet FAILS. Is there a problem with my logic? A problem with the image? What would cause this? How can I verify? i hasve the following code: $filename = "Rainbow-code-1_blck.jpg"; if (file_exists(sfConfig::get('sf_upload_dir') . '/rainbowcode/images/profilepics/'.$filename)) { echo "file found"; $source = imagecreatefromjpeg($filename); } but i get the following warning: Warning: imagecreatefromjpeg(Rainbow-code-1_blck.jpg): failed to open stream: No such file or directory in /home/helloises/traffic_2/phoenix/plugins/rainbowCodePlugin/lib/model/RcProfileTable.php on line 168 i dont understand my file does exist...it goes in to the if cos the echo executes please help i am new to this and have no idea how to fix this thank you Hi,
before posting this problem, I already tried googling and tried those possible solutions that could help but still failed.
I am having a problem with that PHP function
imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error:based from what i found in google, some say, use
ini_set("gd.jpeg_ignore_warning", 1);
failed.
some say, use
init_set("memory_limit", -1)
still failed
I am sure that I am passing .jpg image, how come i keep on getting that error ?
any suggestions of what to do?
Edited by sasori, 23 October 2014 - 08:12 AM. Hey guys, The script I use to generate images, more or less, works almost flawlessly. However, I keep experiencing a problem at random in my script when it comes time to call a JPEG or PNG file from an external server. A lot of the time it will work fine, but many other times it comes back with the error: imagecreatefromjpeg() [function.imagecreatefromjpeg]: Cannot read image data Which causes the script to fail. Right now the images it say it cannot read are these: http://tiles.xbox.com/tiles/UT/EF/1mdsb2JgbA9ECgQLGwMfWSkgL2ljb24vMC84MDAwIAABAAAAAPkqMU4=.jpg http://tiles.xbox.com/tiles/Au/lM/1Wdsb2JgbA9ECgUAGwEfL1hTL2ljb24vMC84MDAwIAABAAAAAPpj6R0=.jpg http://tiles.xbox.com/tiles/6q/kv/1Gdsb2JgbA9ECgUAGwEfL1hSL2ljb24vMC84MDAwIAABAAAAAPsAqfU=.jpg http://tiles.xbox.com/tiles/tQ/UG/1Gdsb2JgbA9ECgUAGwEfV1gmL2ljb24vMC84MDAwIAABAAAAAPspBao=.jpg http://tiles.xbox.com/tiles/qp/Fx/0Wdsb2JgbA9ECgQNGwEfVitXL2ljb24vMC84MDAwIAABAAAAAP5ekbU=.jpg and as you can see, they work fine. So what's going on here? Is Microsoft somehow blocking the attempt? I can view the images fine in the browser, but sometimes it just won't work in the script. But like I said, it's not everytime. The line the errors comes up on are these: $lastxboxgames = imagecreatefromjpeg($lastxboxgames); $lastxboxgames1 = imagecreatefromjpeg($lastxboxgames1); $lastxboxgames2 = imagecreatefromjpeg($lastxboxgames2); $lastxboxgames3 = imagecreatefromjpeg($lastxboxgames3); $lastxboxgames4 = imagecreatefromjpeg($lastxboxgames4); I also have the script to echo the variables back to me when while it's running, so those urls up there came exactly from the script, so it's not that its getting the wrong URL, it just decides that the image isn't good enough. The script, generates my signature image below, and when any of the images that come from the xbox server return an error, they all do, including the avatar image in the top left which is a PNG. Any help is appreciated! I Can't resize large images with imagecreatefromjpeg() I can load small 38kb images fine, when they get up 780+- or 1.3 mb +- (with a width of 2500px * x) I get the below error I also can upload the same pics in another file with out resizing(using imagecreatefromjpeg()) them and the script works fine. my max file upload size with xampp is 128mb / php5 Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg, libjpeg: recoverable error: Corrupt JPEG data: 191 extraneous bytes before marker 0xd9 in C:\xampp\htdocs\ed\phpsol\ch08\work\includes\create_thumb.inc.php on line 35 Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: 'C:\xampp\tmp\php9596.tmp' is not a valid JPEG file in C:\xampp\htdocs\ed\phpsol\ch08\work\includes\create_thumb.inc.php on line 35 I'm basicly using a switch switch($type) { case 1: $source = @ imagecreatefromgif($original); if (!$source) { $result = 'Cannot process GIF files. Please use JPEG or PNG.'; } break; case 2: $source = imagecreatefromjpeg($original); <---- LINE 35 where $original is $original = $_FILES['image']['tmp_name']; break; Hey guys, It's been awhile since I've coded in PHP and I can not for the life of me remember how to do this. Say I have http://www.example.com/search.php?name=joe&size=small What the PHP code to grab the ?name=joe&size=small part? thanks Very simple question. I have a table with courses and a table with students registered for those courses. I have a page where I can change the course name. What I want to do is, when changing the course name in the course table, I want all students in the students table who are already registered for that course to have that course name updated as well in the student table. I'm currently using a field cid to update the courses in the course table however, the student table doesn't have a cid field rather a cname ( course name) which I want to use to update the fields in the student table. Is it possible to use Code: [Select] <a href=\"editcourse.php?cid=" for more than one field of info? i.e transfer the cid + cname and so you can use $_GET[cid]"; and $_GET[cname]"; ? Something like this maybe ( dont know how the code will go) "editcourse.php?cid=&cname=" ? Do I have the right idea for how to go about this? Hi all, Ive latly coded a option for my website which allowes users to send money.

Thanks. hello guys i heard there is a way that you can make something like a database on a text editor and when ever u want to change the info you just open a text editor and change the information How is this called? where can i find a tutorial? any tips? thanks you very much let's say I have 100,000 users on my forum i want to cache there PROFILE INFO (About me) in .php files which is easy/etc but would that be more space than 100k rows in a db table, or 100k .php files? just wondering, prob a stupid question but atm I cache some lottery info and some other stuff, but that's only 1 .php it would be dumb to cache info and have 100k .php's for each user ID right? or maybe story it all in 1 .php? would be a HUGE Filesize? rather just keep the data in MYSQL right? Hi. I have built a form on a page call join.php On this form I pass a variable in this manner; $url = "thankyou.php?val_id=".$validation.""; header("Location: {$url}"); So on the next page (which is the thankyou for registering page I want this page on load to find the user from the $validation and then email the user. I have done this many times but for some reason this time the output is "No database selected!" There really is though. Also I can see in the browser window the code I have passed so its not like that is not working! Here is the code, can anyone see my error because I just have no idea whats up! <?php include(thedatabase.php'); session_start(); $val_id = $_GET['val_id']; $FullRec__query=sprintf("SELECT * FROM users WHERE val_id= %s", $val_id); $FullRec = mysql_query($FullRec__query) or die(mysql_error()); $userInfo = mysql_fetch_array($FullRec); $user = $userInfo['username']; mail($userInfo['email'],"Validation Link From Us","Dear ".$userInfo['username'].",\n\nThank you for signing up to www.thesite.co.uk.

Right now my app just gives the first score and then when I take the test again it just refreshes and gives the new score. I want it to play the new score under the old score.

But now im bit stuck to send it to multiple users. All my visitors unique IDs are being stored into a file called unique.csv all in 1 column under each other. But what im currently trying to do is to recall the info from the csv and make a contact list to broadcast the message to.
The csv file looks like:
27823116700
m59317461002 ok im back quicker than i thought.... i got my drop box sorted and i got it reloading the page. so it all works correctly. but how do i get the page to display information regarding the film i have selected in the drop box.? i have no code for this at the mo. also i would like the drop box to display the selected item at top of box when it refreshes code for drop box: Code: [Select] <FORM> <?php $result = mysql_query( "SELECT * FROM movie_info ORDER BY title ASC ") ; echo "<select name= Film onChange='submit()' >film name</option>"; while ($nt=mysql_fetch_array($result)){ ?> <?php echo "<option value='$nt[id]'>$nt[title] </option>"; } ?> </select> </FORM> any help would be great For some odd reason, my MySQL array is not returning any data. I echo'd the query and it is correct, I looked at the database and that row is in there, but when I print_r the array, nothing. Here is the code. $infoquery = "SELECT * FROM '$endotype' WHERE ID = '$typeid' ORDER BY ID DESC LIMIT 1"; $info = mysql_query($infoquery); echo $infoquery; $infoout = mysql_fetch_array($info); print_r($infoout); Its a very simple query and its driving me nuts. In my script, users login with their Username & Password. However, I'd like to be able to echo the email address used on their account.
I've tried adding the email to the session I'm not having much luck... Here's a piece of the login code(untouched);
$username = $_POST['name'];
$passwd = $_POST['passwd'];
$query = "SELECT name,passwd FROM users WHERE CONCAT('0x', hex(passwd)) = '{$salt}'";
$result = mysql_query($query);
$login_ok = false;
if(mysql_num_rows($result) > 0) {
$login_ok = true;
}
if($login_ok)
{
$row = mysql_fetch_array($result, MYSQL_NUM);
$_SESSION['user'] = $row;
I've also tried messing around with this piece below in a few different ways but still nothing.
<?php echo htmlentities($_SESSION['user']['email'], ENT_QUOTES, 'UTF-8'); ?>Any help is greatly appreciated.. |
