PHP - Creating A Unique Image Name

Hello,   I have a website called http://flappycreator.com/ where users can upload multiple images to create their own version of Flappy Bird.  As a result of this I created a PHP page that takes a GET param to create a preview image of their game to display in various locations on the website.   Here is an example: http://flappycreator...d=5305a9ad9dc30 http://flappycreator...d=5305a9ad9dc30 http://flappycreator...d=5305a9ad9dc30   My issue is, I have given my users the ability to upload PNGs or JPGs and trying to figure out reliable code to display the preview has become a huge hassle.  In the example above the Pac-Man character shows a white background but when you play the game, it is actually transparent.  In other situations I am getting extremely bad color distortion.  The code I have provided is my final attempt after a ton of trial-and-error and the PNG imagealphablending() and imagesavealpha() commands have shown me the best results, however I don't know what they do.   Please help!  Thanks.

Hi,

I need help in my code. I have written a CAPTCHA code, but it is not appearing when I test run in my website. My code is below, could anyone highlight to me my error? Any problems to those that were highlighted in red? Thanks

<?php
  session_start();

  // Set some important CAPTCHA constants
  define('CAPTCHA_NUMCHARS', 6);  // number of characters in pass-phrase
  define('CAPTCHA_WIDTH', 100);   // width of image
  define('CAPTCHA_HEIGHT', 25);   // height of image

  // Generate the random pass-phrase
  $pass_phrase = "";
  for ($i = 0; $i < CAPTCHA_NUMCHARS; $i++) {
    $pass_phrase .= chr(rand(97, 122)); //chr(), convert a number to its ASCII character equivalent
  }

  // Store the encrypted pass-phrase in a session variable
  $_SESSION['pass_phrase'] = SHA($pass_phrase);

  // Create the image
  $img = imagecreatetruecolor(CAPTCHA_WIDTH, CAPTCHA_HEIGHT);

  // Set a white background with black text and gray graphics
  $bg_color = imagecolorallocate($img, 255, 255, 255);     // white
  $text_color = imagecolorallocate($img, 0, 0, 0);         // black
  $graphic_color = imagecolorallocate($img, 64, 64, 64);   // dark gray

  // Fill the background
  imagefilledrectangle($img, 0, 0, CAPTCHA_WIDTH, CAPTCHA_HEIGHT, $bg_color);

  // Draw some random lines
  for ($i = 0; $i < 5; $i++) {
    imageline($img, 0, rand() % CAPTCHA_HEIGHT, CAPTCHA_WIDTH, rand() % CAPTCHA_HEIGHT, $graphic_color);
  }

  // Sprinkle in some random dots
  for ($i = 0; $i < 50; $i++) {
    imagesetpixel($img, rand() % CAPTCHA_WIDTH, rand() % CAPTCHA_HEIGHT, $graphic_color);
  }

  // Draw the pass-phrase string
  imagettftext($img, 18, 0, 5, CAPTCHA_HEIGHT - 5, $text_color, 'Courier New Bold.ttf', $pass_phrase);

  // Output the image as a PNG using a header
  header("Content-type: image/png");
  imagepng($img);

  // Clean up
  imagedestroy($img);
?>

Been just trying to test out some basic code that utilizes gd.  In Chrome i receive a blank page.  In firefox I get "The image "image.php" cannot be displayed because it contains errors".  There is no whitespace before or after the php tags, which seems to cause this error sometimes. 
 
$image = imagecreate(200,20);
$background = imagecolorallocate($image, 0, 0, 0);
$foreground = imagecolorallocate($image,255,255,255);
imagestring($image, 5, 5, 1, "Test", $foreground);
header("Content-type: image/jpeg");
$imagejpeg($image);

I am just following a tutorial, and at this point in the tutorial i should get at least some garbled text, if not an image.

I looked at other common causes.  gd2 is un-commented in php.ini.

phpinfo shows:
GD Support   enabled
GD Version   bundled (2.0.34 compatible)
FreeType Support   enabled
FreeType Linkage   with freetype
FreeType Version   2.4.3

I have not found any other solutions to try, or maybe I have made an error is checking these solutions.  Any advice with be great!  Thank you for your time.

Hi there

I've been working with some code to display a single
record on page. This all works fine and I'm able to pull what I
want from the database. My problems is trying to use that
data and turning it into something else like a link.

I have a field in the database called image url which
contains rows of image urls.

So here is the problem area of the code:

Code: [Select]
<?php
//////Displaying Data/////////////
$id=$_GET['id']; // Collecting data from query string
if(!is_numeric($id)){ // Checking data it is a number or not
echo "Data Error";
exit;
}

$fetch=mysql_query("select * from productfeeds where ProductID=$id ");
$row=mysql_fetch_object($fetch);
echo mysql_error();
echo "<table>";
echo "
<tr><td><b>ProductID</b></td><td>$row->ProductID</td></tr>
<tr><td><b>ProductName</b></td><td>$row->ProductName</td></tr>
<tr><td><b>ProductPrice</b></td><td>$row->ProductPrice</td></tr>

//problem area for me
<tr><td><b>Image</b></td><td>$row->ImageURL</td></tr>
echo "</table>";
I'm trying to edit this part of the code:

<tr><td><b>Image</b></td><td>$row->ImageURL</td></tr>

I've tried this:

<tr><td><b>Image</b></td><td><a href='{$row['URL']}'> <img src='{$row['ImageURL']}'></a>

and

<tr><td><b>Image</b></td><td><a href='$row['URL']'> <img src='$row['ImageURL']'></a>  //removed brackets

but I'm just getting errors. Can you guys help please?

Thank you very much.

Hello Forums,
So basically I am trying to place text over an image.
It works but the max text size is 5 which is way too small for my needs!
What can I do to increase the size of the text? 
If anyone can help it would be much appreciated.
 
Here is my code:
Code: [Select]
<?php
  $title = $_REQUEST['title'] ;   
$my_img = imagecreatefrompng ( "Template.png" );
$text_color = imagecolorallocate( $my_img, 0, 0, 0 );
imagestring( $my_img, 5, 30, 25, "$title",
  $text_colour );
header( "Content-type: image/png" );
imagepng( $my_img );
imagecolordeallocate( $text_color );
imagedestroy( $my_img );
 ?>

Hi group,

  I need to create a string to be used by base64_encode to build an SVG file. The source for the string is an image I built in memory. Code: [Select]
$img = imagecreatetruecolor( 50,50 );
Other stuff, draw circles, test, ect.
I currently write it out to disk with: Code: [Select]
imagepng( $img, "$Name.png" );

Then read it back in and process it to create an SVG file.

I would like to avoid writing it to disk, so how can I create a string for base64_encode from an in memory image??

Thanks for your time.

Greetings,

What I'm trying to do is have users upload their event information into a database which would include a flyer.  I don't want the image file to go into the database (other than the filename) rather I'd like it to be dropped into a directory.  In the same script I'd like to dynamically generate a thumbnail.  I have the two scripts and separately they work fine, but I can't get them to work together.

I'm guessing the conflict because the thumbnail script is using $_POST and the mysql script is using $_SESSION.  If so how can I modify them to both use $_SESSION?

The thumbnail script is goes from line 1 - 146 and the mysql portion is the rest.

The results of processing this look something like this.

QUERY TEXT:
INSERT INTO td_events (eventgenre_sel, eventname, eventvenue, eventdate, eventgenre, eventprice, eventpromoter, eventflyer) VALUES ('12', 'spooky times', 'Ironwood Stage & Grill', '2010-12-17 22:36:00', 'DNB', '5000', 'me', '174366-1.jpg')

PLease help me PHP friends to correct my codes.

Need a bit of help with some php and a few kind members helped me in the past.

My code is:
$query = "SELECT names FROM table WHERE type='$type'";
$result = mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_array($result)) { 
foreach(unserialize($row['names']) as $key => $value){ 
echo $value . '<br />'; 
} 
}

Basically, a field on my table is called names. The information in this field is serialized (so many names are together in a single field, for a single row).

I want to be able to search the whole table (where type='$type' - so many rows) for all names and then show unique names only.

My code above unserializes the names from each field and then lists them, but doesn't deal with any duplicates (which I need removing).

I have looked at functions like "unique_array()", and have tried using it in different places but it isn't doing the job.

Any help appreciated.

Hey everyone. I have been working on a cart for my site and I've reached an impasse. I coded up the cart, the add to cart, the delete from cart and the subtract from cart. Problem is I now see a need to put an image for everything that is added to the cart. I think i have devised a way to do it with frames, the left frame being the cart and the main frame is purely for the images. I am having trouble getting the code right between the two pages to work. I need a picture on the right of every item added to the cart. Here is the url for the cart: http://www.theblack44s.com/Merchant%20pages/index3.php

I know this kind of thing can get extensive and I don't mean to take up any more of your time than necessary so if there are any suggestions or ideas of where I can find this information to learn it that would be just as good. Hey thanks for your time!

I have a foreach parsing as
foreach ($posttags as $tag) {
$test = $tag->name;
$pattern = "/something/";
if(preg_match($pattern, $test)) {
$test2 = "$test is $test";
echo $test2;
}
}


I selected those containing a given word, but I do not know how to remove duplicates to have uniqueness. I was unable to use array_unique, as I am within a foreach loop.

Hey guys. I need to know how to get a time that is constant. What I want to achieve:
I need to make a clock on my website showing only one time (HH:MM:SS), wherever the page is requested from.
And I need to use this "time" in calculations, like finding the time difference between two time values stored in my MYSQL Databases.
I hope that I am clear with my question.
Thanks for any help in advance! 

ok so i have an array which has duplicate values in it.

i used array_unique() to remove duplicate values.

the array had values 1,2,2,3.

after the following code:


$unique = array_unique($suggest);
$size = count($unique);
for ($x=0;$x<=$size;$x++)
{

     echo $unique[$x];
echo "<br>";
}



it prints out 1,2 and then gives an error, "Notice: Undefined offset: 2 in E:\wamp\www\Copy of pro2\Classes.php on line 1074" and then finally 3.

any ideas  how i can solve this.

im assuming that array_unique() assigns the index 0,1,3 of the duplicate value array to unique array at the same indexs 0,1,3. since the index 2 of duplicate array is a duplicate value it is ommited but the unique array does not have an array at index 2.

Hey everyone!

My upcoming site will host, potentiallly thousands of photographs, and i was wondering how to go about having a unique ip hit counter for EACH image.

Obviously i dont want people refreshing the page to gain hits, therefore the hit counter will need to be dependent on the IP address.
I have used google and found a few hit counters however i need to know how to make this practical as it seems like it will require a lot of databases!


Thanks in advanced, Jimmy.
