    watermark on all images in a folder

    in PHP Coding Help

    Posted

    I want to add a water mark to all images within a particular folder and then save them in another location?? is this a simple thing to do ?

     

    Just alter this line: 

    imagejpeg($image);

    to 

    // $newdir is the new folder where you want to save watermarked images -- relative to where the script is (and make sure it ends in a trailing slash)
$newdir = "../../new_folder/";

// JPEG quality is from 0-100 -- 90-95% will give you approximately your original filesize for the watermarked image
$quality = 90; 

// Save the file to disk
imagejpeg($image, "{$newdir}{$_GET[path]}", $quality);

     

    Make sure you place the script in the folder where your images are. Then call watermark.php?path=image.jpg

    The watermarked image will be saved in the folder that $newdir points to.

     

    You'll have to manually call each file through this script to get it watermarked.

    [SOLVED] Ping Multiple sites with script

    in PHP Coding Help

    Posted

    If you just need to hit some sites in order to keep it from inactivity, just do this:

     

    <?php
$a = file_get_contents("http://yoursite1.com");
echo "Site#1 is " . strlen($a) . " bytes long.<BR><BR>";

$b = file_get_contents("http://yoursite2.com");
echo "Site#2 is " . strlen($b) . " bytes long.<BR><BR>";
?>

     

    You get the point on how to do this for multiple websites...

    [SOLVED] Header CSS Location Help

    in PHP Coding Help

    Posted

    I believe you're saying you're putting the link to the CSS file in each page of your site. And some of these pages reside in a different folder, so the path to the CSS is wrong.

     

    If so, your URL just needs to be spruced up a little. From the root of your domain, trace the path. If CSS is a directory under the root directory, your code would be:

    <link href="/css/default.css" rel="stylesheet" type="text/css">

     

    Notice the slash beginning the URL. That will make all the difference.

    Help with Remote Files

    <?php
echo webcopy("http://calvarybucyrus.org/CBC-50.jpg", "./");

function webcopy($source, $destdir) {
$filename = $destdir . basename($source);
$a = file_put_contents($filename, file_get_contents($source));
if ($a > 0) {return "{$a} bytes written to {$filename} from {$source}";}
else {return "We had a problem with this query.";}
}
?>

     

    This will preserve the original filename and is more similar to your code.

    Help with Remote Files

    in PHP Coding Help

    If you're using PHP5 and fopen wrappers enabled, try this:

     

    <?php
$url = "http://calvarybucyrus.org/CBC-50.jpg";
$filename = "./savedfile.jpg";
$a = file_put_contents($filename, file_get_contents($url));
if ($a > 0) {echo "{$a} bytes written to {$filename} from {$url}";}
?>

     

    You could turn it into a function easily. It simply fetches a remote image and saves it locally.

    watermark on all images in a folder

    in PHP Coding Help

    Posted

    This is interesting concept I want to look into. Does it put a water-mark on all image perminantly or just whenever loaded into php script ?

     

    No. It dynamically adds the watermark. The image it outputs isn't saved to disk. If you want it to, you'd need to modify the source code, which is fairly easy.

    [SOLVED] session login :(((

    in PHP Coding Help

    Posted

    Something else to think about...

     

    You can set the length of the session by using a persistent session. This length is from the end of the last logged-in request.

    This will effectively log them off after xx minutes of inactivity.

    Note that the length before expiry is user-side. It's up to their browser to comply with the length of the cookie.

     

    <?php
$length = 3600; // length in seconds of session --> 3600 seconds = 1 hour
session_set_cookie_params($length, "/", ".yourdomain.com");
session_start();   //Start session

// Your PHP code here
?>

     

    Be sure to replace yourdomain.com with your domain name.

    watermark on all images in a folder

    in PHP Coding Help

    Posted 

     $dr=preg_replace('/modify\.php.+/', '', $_SERVER['PHP_SELF']);
$filename=str_replace($dr, './', $_SERVER['PATH_INFO']);

     

    Here's the problem: It's not getting a filename properly.

     

    If you absolutely don't want users downloading the file without the watermark, the images need to go in a folder that is not web-accessible.

    Then you need to format how the script will get a filename. You might use a query string from a hard-coded path.

     

    Example:

    Images in this folder: /images

    $directory = "/images/";
$filename = "{$directory}{$_SERVER[QUERY_STRING]}";

     

    Image file: /images/test.jpg

    HTML code: http://yoursite.com/path/modify.php?test.jpg

    (Of course, you'd want to rename modify.php to something like image.php)

    code to check if HTML source has changed.

    becuase I am using php 4 I get an error if url.txt doesnt exist.

     

    I get:

    Filesize of URL: 2478

     

    Md5 of URL: 3c3cdd8df4c3c0314def598ace9af0a0

     

    Fatal error:  Call to undefined function:  file_put_contents() in /

    .... on line 6

     

    Why do u think when I create the file and then copy and paste the pages source code in there it returns what I previously posted and they dont match.  When it gets written to url.txt(when url.txt doesnt exist) -- when u view it what shows up?

     

    I have PHP5. File_put_contents must be a PHP5 command.

    Your problems are probably related to line breaks when you copy the code. If you forget just one of them (there may be extras at the end of the file), it won't match.

     

    But I see you got it working! That's great.

    getting last update time of mysql table

    in PHP Coding Help

    Posted

    Your code needs to look something like this:

    $result = mysql_query("SHOW TABLE STATUS FROM table_name;");
while($array = mysql_fetch_array($result)) {
print_r($array); // Will print information about each table stored in database
}

     

    $result returns a resource. You need to use one of the mysql php functions to use it.

     

    BTW, I'm using InnoDB for my tables, and unfortunately it doesn't record a last update time.

    http://www.getid3.org/ will retrieve all the ID3 information.

    Put this script in the root folder of the extracted download.

     

    <PRE>
<?php
$filename = "/path_to_mp3_file.mp3";

require_once('getid3\getid3.php');
$getID3 = new getID3;
$fileinfo = $getID3->analyze($filename);

echo "Bitrate: {$fileinfo[bitrate]} <HR>";

print_r($fileinfo);
?>

    Put this on the new page.

    As for the blank entries, replace the code below:

     

    // Output your records for this page
echo "<table>\n";
for ($s = $start_key; $s <= $end_key; $s++)
{
if (file_exists("news/" . $list[$s])) {
  // Do your output however you like
  $newsData = file("news/" . $list[$s]);
  $newsTitle  = $newsData[0];
  $submitDate = $newsData[1];	
  unset ($newsData['0']);
  unset ($newsData['1']);

  $newsContent = "";
  foreach ($newsData as $value) 
  {
    $newsContent .= $value;
  }

  echo "<tr><th align='left'>$newsTitle</th><th align='right'>$submitDate</th></tr>";
  echo "<tr><td colspan='2'><br>".$newsContent."<br/><br><hr size='1'/><br></td></tr>";
}
}
echo "</table>\n";

    For some strange reason, the file generated from the fisrt block of code, can't be read by the mp3 player (Windows Media Player), and the second block of code, returns the following error messages. WHY IS THIS? - I couldn't find any lines without semi-colons, they all have one as far as I can see.

     

    Warning: filesize() [function.filesize]: stat failed for upload/PhilCollins-AnotherDayInParadise in C:\Documents and Settings\Dale Piper\Desktop\Xampp\htdocs\Copy of Preview.php on line 4

     

    Warning: fopen(upload/PhilCollins-AnotherDayInParadise) [function.fopen]: failed to open stream: No such file or directory in C:\Documents and Settings\Dale Piper\Desktop\Xampp\htdocs\Copy of Preview.php on line 8

     

    Warning: fread(): supplied argument is not a valid stream resource in C:\Documents and Settings\Dale Piper\Desktop\Xampp\htdocs\Copy of Preview.php on line 9

     

    Warning: fread(): supplied argument is not a valid stream resource in C:\Documents and Settings\Dale Piper\Desktop\Xampp\htdocs\Copy of Preview.php on line 10

     

    Warning: fclose(): supplied argument is not a valid stream resource in C:\Documents and Settings\Dale Piper\Desktop\Xampp\htdocs\Copy of Preview.php on line 12

     

    Maybe you forgot the mp3 extension on the filename???

    Looks like obsidian code works... :)

    But there is some issues..

    Now I have 7 news in my page.. and when I go to page 2 it shows the last 2 posted.. and after that it shows several lines (the lines that seperates the news)..

     

    And is it possible to make pagination appear on the bottom of the news.. in the center?

     

    Thanks in advance :)

     

    Just put the // Print Pagination section under the article display and put

    echo "<center>";
// Print pagination section goes here
echo "</center>";
