PHP - Image Rotate Losing Transparency

Hi,

There are 10 images in a folder called "Images".
All images are named like 1.jpg, 2.jpg, 3.gif, 4.png, and so on...

I am using these images on my website with this link: MyDomain.com/Images/1.jpg
Now what i want to do is change the image every minute.

from 1... to ...10 all images one by one, every minute...

Link should remain same, but it should give different image every time.
and if someone copies my link of image, it still gets changed every minute.

i hope to get some help, better with some example code...

Thanks!

Hey guy's i have a script i did a few months ago and now noticed that it is doing its job but keeps the old file ..so i got the image a few times but on a different angle...

 

how can i optimize this code to delete the old image when doing the rotation?

 

<?php
session_start();
include_once 'dbconnect.php';
if (!isset($_SESSION['userSession'])) {
	header("Location: index.php");
}

$degrees = -270;
$path = $_GET['Folder'];
$file =$_GET['Pic'];
$fileid =$_GET['id'];

$image = $path.'/'.$file;
$imageN = $path.'/New_'.$file;
//load the image
$source = imagecreatefromjpeg($image);

//rotate the image
$rotate = imagerotate($source, $degrees, 0);

$NewImg='New_'.$file ;

//set the Content type
//header('Content-type: image/jpeg');

//display the rotated image on the browser
//imagejpeg($rotate);
imagejpeg($rotate,$imageN,100);
//free the memory
imagedestroy($source);
imagedestroy($rotate);
$sql = "UPDATE Coupon_list SET product_image_thumb = '$NewImg' WHERE id = '$fileid'";

if (mysqli_query($DBcon, $sql)) {
   echo "Rotation ok";
echo('<script language="Javascript">opener.window.location.reload(false); window.close();</script>');

} else {
   echo "Error Rotating: " . mysqli_error($DBcon);
}
mysqli_close($DBcon);
?>

How to do that when you turn 360 degrees no longer come back? Only in this way was?

I am not sure If I am loosing my variable or if it is just getting cancelled out by the syntax.
The error I get is this:
Query string: "SELECT * FROM timeslip WHERE 1 and Initials=" ORDER BY "Date" ASC, "Cost" ASC
Failed with error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"SELECT * FROM timeslip WHERE 1 and Initials=" ORDER BY "Date" ASC, "Cost" ASC' at line 1

Initials should have the value of GEC at this moment

Here is my code:

   $Initials=$_POST['Initials'];  
   $qry_str.='and Initials="'.$Initials . '"';

   $qry_str.="and Date >= $start and Date <= $end "; 
}
if($_POST['order1'] && $_POST['order2'])
{
$order1=$_POST['order1'];
$order2=$_POST['order2'];
$qry=$_POST['qry'];
$qry_str=' "'.$qry.'" ORDER BY "'.$order1 . '" ASC, "'.$order2 . '" ASC ';

Alright I know scraping is frowned upon.. but its for a client...  Anyways.. The below is supposed to form an array $kw for output. But its breaking on line 27:
Code: [Select]
  foreach ($kw as $keyword => $pages) 
Ive concluded my array is being broken and then formed into an empty string, but I can't figure out where it wen't wrong.

I want to say the trouble comes from lines 20-23:
Code: [Select]
  foreach($data as $temp) {
    $kx = text_between('"','"',$temp);
    if (is_array($kx)) $kw[key($kx)] = current($kx);
  }


The full version..

Code: [Select]
<?php
function text_between($start,$end,$string) {
  $keyword = '';
  if ($start != '') {$temp = explode($start,$string,2);} else {$temp = array('',$string);}
  $temp = @explode($end,$temp[1],2);
  $temp2 = @explode($end,$temp[1],3);
  $pages = (int)@str_replace(',','',$temp2[1]); 
  if ($pages) $keyword[$temp[0]] = $pages;
  return $keyword;
}

function gsscrape($keyword) {
  $keyword=str_replace(" ","+",$keyword);
  $keyword=str_replace("%20","+",$keyword);
  global $kw;
  $data=file_get_contents('http://clients1.google.com/complete/search?hl=en&gl=us&q='.$keyword);
  
  $data=explode('[',$data,3);
  $data=explode('],[',$data[2]);
  foreach($data as $temp) {
    $kx = text_between('"','"',$temp);
    if (is_array($kx)) $kw[key($kx)] = current($kx);
  }
}
#simple to use, just use yourscriptname.php?keywords
echo $_SERVER['QUERY_STRING'];
if ($_SERVER['QUERY_STRING']!='') {
  gsscrape($_SERVER['QUERY_STRING']);
  foreach ($kw as $keyword => $pages) {
      gsscrape($keyword);
  }
}
#all results are in array $kw...
echo "<pre>";
print_r($kw);
echo "</pre>";
?>

I seem to be losing my array value when it comes to the "Game Time" section of my script. I am printing out the array a long the entire time and this is where I lose it and can't figure out why.

Maybe somebody knows a good way to do this... I have a simple query that seasonal categories - plus one special events header. then for each header I pull all the classes in that category. Right now it just pulls and orders by id. So, regardless of year, they come out in the same order: spring, winter, fall, special events. I'm trying to see if there's a way to make them show in order of relevance to the current time. right now, the "cat" table just has two fields: cat_id, cat_name.

In other words,
in autumn, I want them to order: Autumn, winter, summer, spring - then special events.
In summer, I want them to order: Summer, spring, autumn, winter - then special events.

any thoughts on how to do this? step one, order by relevence to current date. step two, special events is always last.

Code: [Select]
$query1 = "select * from tbl_cat ORDER by cat_id";
$result_cats = mysql_query($query1) or die(mysql_error());


while ($row = mysql_fetch_array($result_cats)) {

$query_selectall = "select *,workshop_date AS tester from tbl_workshops WHERE category={$row['cat_id']} and active_inactive = '1' ORDER by workshop_date";
$result_all = mysql_query($query_selectall) or die(mysql_error());
$catid = $row['cat_id'];

$catname = $row['cat_name'];
echo "<font face='georgia' size=5><b>".$catname." </b></font><br><div style='color:#fff;'>";

while ($c_row = mysql_fetch_array($result_all)){

// rest of code pulls items that match that specific category id.

}      

Alright, I've spent over a week trying to fix this now - And Im getting frustrated! I asked at other forums, I asked co-workers and I asked friends-of-friends, and nobody can explain what happens. Let's take a look at this first:

$name = mysql_real_escape_string($_POST['name']);
mysql_query(sprintf("UPDATE em_users SET name='%s' WHERE id='" . $in_user['id'] . "'", $name));

This will insert NO data on the Name field in the database. Obviously, I thought the $_POST variable wasn't passed correctly, but echo'ing it just before the query WILL show data. And as I said, I tried everything possible for the last week. Switching variables, adding static text on the $name variable instead of using the $_POST content (this does work). I used very very simple test data on the form, such as my name "Mark" or "test" and "hey". The query is correctly executed everytime.

The truely WEIRD thing is, if I ensure there is content in $name before executing the query it will work as expected everytime. Like this:

$name = mysql_real_escape_string($_POST['name']);
$name && mysql_query(sprintf("UPDATE em_users SET name='%s' WHERE id='" . $in_user['id'] . "'", $name));

Of course I could do this, but I want to know why my code does or doesn't work + it's a lot of work to do for something that worked fine a week ago. It has spread to a lot of forms on my website that $_POST variables aren't processed correctly - and it happened out of nowhere. Even on codes that havnt changed in months.

I really need help on fixing this! This project has been in development for nearly two years, and without a fix it's pretty much lost

Hi everyone - I am trying to figure out how I can allow my logged in users to leave a php page and go to an html page without losing them as "currently logged in" - I have a site that is mixed with html and php pages and this is what I am needing: i have a user, they are logged in and are visiting a php page. then they want to go to another page(only logged in users can access the php page) - so they click on the html page they want to go to, great! - but then they want to visit another page that is a php page and requires them to be logged in in order to access it. How can i accomplish this without having them log in yet again? is this possible? i am using sessions.

Hey there,

Pretty frustrated with this. It seems so simple, but I've been staring at it and toying with it for ages, so I figured I'd post here. I have a variable called "$isTaken" that seems to be losing its value in an essential step in my function. Take a look.

function subdomainTaken($inputtedSubdomain)
{
//Initialize $isTaken to 'true'
$isTaken = true;
echo "isTaken STARTS AS: <i>" . $isTaken . "</i><br />"; //FOR TESTING PURPOSES ONLY. VARIABLE HAS VALUE HERE

//Check subdomain in database
$subdomainDBQuery = mysql_query("SELECT * FROM `companies` WHERE company_subdomain = '$inputtedSubdomain'");
$foundResult = mysql_num_rows($subdomainDBQuery);

if ($foundResult > 0) {
$isTaken = true;
} else {
$isTaken = false;
}
return $isTaken;
}


By the time I get to the if statement, $isTaken has no value. I've echoed it to be sure. Any ideas?

Thanks,
Frank

I am working with a fellow who runs an eCommerce shop. The transaction resolution comes in on a querystring.   I do not yet know what web server software is being used, nor if any security appliance/software is installed.   One of the values in the querystring starts with the @ character.   We know the web server gets this as there entries in the web server's access log that shows thing value is present.   It is not available in PHP's $_GET array.   We are trying to get an idea of where this value, and it's key, is getting discarded.   Is there a known problem with (actual server software being used not yet known) web server software discarding a key/value if the value has the @ character in the querystring?    

I am trying to retain information from the $get variable after checking if a user, (Joomla code), is logged in but it is not working. (url: http://domain.com/script.php?file=data)

define( '_JEXEC', 1 );

define('JPATH_BASE', '/path/to/joomla/dir/');
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
$session =& JFactory::getSession();
$user =& JFactory::getUser();
// get username and name of user
$username = $user->get('username');
$name = $user->get('name');
if (empty($username)) {
    die('Not logged in');
}
   $file = $_GET['file'];
   echo &file;
   exit;
Any help appreciated.

Afternoon,

Not sure if i've been staring at the screen for too long or not, but have a log in script which saves the password as a session variable and I can pass that variable across my page like so:


<?php 
  session_start();
  //Print_r ($_SESSION);
  echo "Erm, I have reached page.php and the password is ".$_SESSION['password'];
?>


However, I want to make this secure, so I added a function to it which when you log in says if $_SESSION['password'] does not exist then send me away, like so:


<?php 
session_start();

function checklogin()
{
 session_start();
  if(!isset($_SESSION['password']))
{
       header("location: /index/");
       exit;
}
}

  checkLogin();
  Print_r ($_SESSION);
  echo "Erm, I have reached page.php and the password is ".$_SESSION['password'];
?>


However, using the function and a valid log-in it (as shown above) it chucks me out of the page even though $_SESSION['password'] exists?

Am I doing something really stupid here?

Thank you

So whether I am uploading an image through my iphone or sending that image to my computer and uploading it from the computer, it has the same effect. If I upload that image, it'll orient the image in landscape mode.

Having said that, I found a function that can fix the orient issue. The problem is I don't know the proper way to integrate it into the image upload script. I have tried several different ways but they all give me errors. Can you show me where exactly I should use this function?

// IMAGE ORIENTATION 
function getOrientedImage($imagePath) {

	$image = imagecreatefromstring(file_get_contents($imagePath));
	$exif = exif_read_data($imagePath);

	if(!empty($exif['Orientation'])) {
		switch($exif['Orientation']) {

			case 8:
				$image = imagerotate($image,90,0);
				swapHW();
			break;

			case 3:
				$image = imagerotate($image,180,0);
			break;

			case 6:
				$image = imagerotate($image,-90,0);
				swapHW();
			break;
		}
	}
	return $image;
}

// IMAGE UPLOAD SCRIPT

  if(is_uploaded_file($_FILES['fileToUpload']["tmp_name"])) {

    $resized_image = compressImage($source_file, $new_image, 50);
    $new_file_path = $target_dir . $resized_image;

    if(!is_dir($target_dir)){
      mkdir($target_dir, 0775, true);
    }

    $uploadOk      = 1;
    // Check if image file is a actual image or fake image
    $check = getimagesize($source_file);
    if($check !== false) {

Hello,   I have a secure login script that uses sessions to maintain a users logged in status. I regenerate the session ID on each page reload for added security. Sometimes, I will lose sessions, and I am hard time figuring out why. It seems to be when I have a slow internet connection. I am wondering what could be causing this?? I have a few ideas, do any of these seem plausible.   -A max execution error, returns a fatal error. -An ajax request get sent before the previous request returns, so the session ID's dont match an I am kicked out.   Any other ideas would be helpful.   Best,   James
