PHP - Help With String Manipulation

I am currently working on a website where users can go and upload images and select different types of filters for the images and then let the user see the result of the filter. This has all gone fine and the image filters are working, the only problem I am having is trying to add a function that allows the user to convert the image so that it looks like a Polaroid. I have seen sites that do similar things but cant work out how its done, wondering if someone could shed some light on the whole area?
thanks

Right, I have a 2 part question. At the moment, each user has an image stored for them which is linked to via a field in the database.

Now I'm showing the image by a simple <img /> tag and just including the result of the filename from a database query, which works perfectly fine but I want to take this a step or two further.

1) Firstly, is it possible to get variables of width, height etc for images that are stored on the server as a file? Much like this information can be accessed when a user uploads an image, is it possible to do it if I'm showing the image once it's uploaded and stored?

2) If I can get dimensions for the image, is it possible to SCALE it properly down to a suitable size? For example, the maximum image can be 50 x 50, but images that are smaller would be scaled up PROPORTIONALLY or if they were bigger they would be scaled down PROPORTIONALLY. For example, if an image is 100 x 200, I don't want it scaled down to 50 x 50, I want it so that it remains to scale and is scaled down to 25 x 50.

I am building an application that creates a label for a manufacturing company... it finds an appropriate font size for given text, and then draws it and displays the image as a bmp(it is required to be a bmp).  That is all fine and dandy and working correctly.  The problem is that the label must have a depth of 2 bits for it to work correctly on their machine...I am using the following code, but cannot get a bit depth lower than 24.  iMagick and GD are both available on the server.

Code: [Select]
$text = $_GET['text'];

if (isset($text)) {



$image = new Imagick();
$image->setResolution(71.5, 71.5);
$image->newImage(160, 40, new ImagickPixel('black'));

$draw = new ImagickDraw();
$draw->setFillColor('white');
$draw->setStrokeColor(new ImagickPixel('black'));
$draw->rectangle(0, 0, 159, 39);

$font_size = 25;
$font_name = 'arial.ttf';

do
{
$font_size--;
$bbox=imagettfbbox($font_size, 0, $font_name, stripcslashes($text));
$right_text = $bbox[2];
$left_text = $bbox[0];
$width_text = $right_text - $left_text;
$height_text = abs($bbox[7] - $bbox[1]);
}
while ($font_size>9 && ($height_text>40 || $width_text>160));

if ($height_text>40 || $width_text>160 || $font_size<10)
{
echo 'The text given will not fit on the label.<br />';
}
else
{
$draw->setFont($font_name);
$draw->setFontSize($font_size);
$draw->setFillColor('black');
$draw->setTextAntialias(false);
$draw->setGravity (Imagick::GRAVITY_CENTER);
$draw->annotation(0, 0, stripcslashes($text));

$image->drawImage($draw);
$image->blackthresholdImage( "#999999" );
$image->whitethresholdImage( "#999999" );

$image->setImageType(1);

$image->setImageFormat('bmp');

$image->writeImage("flavor_labels/".$text.".bmp");
echo '<img src="flavor_labels/'.$text.'.bmp" /><br /><p>Right click this image and click Save As or Save Image As.  <br />Enter in the desired label name and save it to the desired destination.</p>';

}

}

Hello,
I had this case:
Text is stored in mysql table in the means of html, i.e. it contains <p> ,<br /> .... I want to display it on a php page, I had 2 questions:

I want to display the first 400 characters, then the second 300 each on different <div> , so I need to save them each on different variable? and what about html tags?
Thanks

Hi have an array() in which I would like to manipulate certain elements:

Code: [Select]
Array
(
    [TESCO] => Array  (
            [Veg] => Array (
                    [Potatoe] => 12
                    [Cabbage] => 24
                    [Cucumber] => 56
                )
            [Meat] => Array (
                    [Chicken] => 54
                    [Beef] => 89
                )
        )

    [ASDA] => Array (
            [Veg] => Array (
                    [Potatoe] => 12
                    [Cabbage] => 24
                    [Cucumber] => 56
                )
            [Meat] => Array (
                    [Chicken] => 23
                    [Beef] => 90
                )
        )
)

How would I go about adding the price of my meat section together e.g. Chicken + Beef from ASDA = 113

Also how to add/remove elements from Meat/Veg?
Like adding Pork

Cheers

I am trying to find a workaround for people using bookmarks and executing them simultaneously forcing a script to run thousands of times in just a second. Is there a way I can implement a token or a short bit of javascript that would force the user to use the link vs bookmarked URL pages?

Sorry if I am being vague here but its really causing me issues having people doing this on my site.

Hi all,

I have heard stories that hackers/viruses or basically something that you don't want uploaded to a server through a website form have been able to type some sort of code in to a html form field to access information.

I know how to control the length of fields, how to validate that an email address is in the correct format etc. - but when it comes to having a textfield for the user to add up to 2000 characters of their own words, how can I protect from malicious code being inserted?

The textfield is located inside the user area but anyone can join, so anyone ultimately can enter code!

Thanks for the help. 

Hi. I have text files in the directory that contain rapidshare.com links. Now what I need to do is take them one by one and check links inside them one by one using rapidshare API.

Everything works fine apart from one thing.

It reads files and deletes the ones containing dead links but the problem is that it only deletes the file if ALL links are dead, but not when only one link is dead or some of them.

Code:

Code: [Select]
<?php
function rs_check($url){
if (!$url) return false;
$files_pattern= '/\/files\/([^\/]*)\//';
$filename_pattern= '/\/files\/.*\/(.*)/';
preg_match($files_pattern, $url, $matches_id);
preg_match($filename_pattern, $url, $matches_name);
$res= file_get_contents("http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub=checkfiles_v1&files={$matches_id[1]}&filenames={$matches_name[1]}");
list($fId,$fName,$fSize,$fServerId,$fStatus,$fShortHost,$fmd5) =explode(',',$res);
return ($fStatus==1 || $fStatus==2);
}   
$directory = "download/"; 
$linksfiles = glob("" . $directory . "*.txt"); 
foreach($linksfiles as $linkfile)
{
$lf = file_get_contents($linkfile);
$purefilename = str_replace($directory, "" , $linkfile); 
if($purefilename != "5100c00fdb545e12e8cb4f9c5f69ec21.txt"){
if(rs_check($lf) != 1){
unlink($directory . $purefilename);
echo("<br />");
}
} 
}
?>

In this Result I have 2 Rows in result to show, I mean I need to merge the data of First (0th) and Third(2nd) element because it display the
data of same item. So How it can done, I am working in that whole day but not get a solution fully.... I saw a near solution like :


<?php
 
$input = array(
 
                0 => array ( 'id' => 160, 'payment_period' => 'Monthly', 'plan_payment_type_id' => 171, 'payment_type_id' => 4), 
                1 => Array ( 'id' => 160, 'payment_period' => 'Monthly', 'plan_payment_type_id' => 172, 'payment_type_id' => 5), 
                2 => Array ( 'id' => 161, 'payment_period' => 'Weekly', 'plan_payment_type_id' => 173, 'payment_type_id' => 9), 
                );  

echo "<pre>"; 
print_r($input);
echo "</pre>";  
echo "****************************************************************************";
$output = array();
$id_array = array();
$i = 0;
foreach($input as $key=>$val) {
        if(array_key_exists($val['id'],$id_array)) {
                $pos = $id_array[$val['id']];
                $output[$pos]['payment_types'][] = array('plan_payment_type_id'=> $val['plan_payment_type_id'],'payment_type_id' => $val['payment_type_id']);
        } else {
                $output[$i] = array('id' => $val['id'],'payment_period' => $val['payment_period'],'payment_types' => array(array('plan_payment_type_id'=> $val['plan_payment_type_id'],'payment_type_id' => $val['payment_type_id'])));

                $i++;

Anes P.A 

Hi all, been a while since I've been on here.   I am in the process of designing a site similar to dating sites like plenty of fish, or ok cupid. The only spot I am running into trouble is with images.    If you are familiar with either of these sites, you will understand what I am looking for.    Basically, a user is able to upload one or more images via an uploader (Not sure if it's ajax or flash to be honest, but I would like to stick to PHP/Ajax).   While uploading, they have the ability to crop their images to specific sizes set by the site - for example, the image must be cropped to fit  a 400 px X 400 px area, so they have the ability to decide which part of a larger image is saved rather than just have the system crop it and perhaps not show what was intended.    After they finish and click upload, the image is saved to the server, as well as a thumbnail, which, without a refresh, is then added to their page along with their previous images if there were any. From that point, they have the option to delete images they don't like, set the main image for their profile and edit/add captions to the images, again, all without refreshing the page.    Would anyone happen to know of a script I could start with and change to suit my needs, but that would pretty much allow this kind of image uploading/manipulation? I've done google searches for hours now and have looked at a ton of scripts but not a single one I have found seems to be able to do any of these things. Most just have multiple file uploads with cropping ability, but not by the users themselves, just a predetermined dimension.    Any help pointing me in the right direction would be greatly appreciated.    Jax

Please help!
User enters Date (that is somewhere in future, few hours or maybe few years).
I need to store in MYSQL Date minus 6 hours keeping in mind daylight savings time.
I tried to convert date to unix timestamp and subtract 6*60*60. Works great, but does not take into consideration daylight savings time.

I have my data array which i converted to json by splitting the keys using for each loop.

The next thing i want to do is to unset the keys or entire inner objects of the json.

Keeping in mind the following conditions:

1.If all the keys in the objects are 0 then the entire object will be removed (easy part). 2.If a key in the object has any value other than 0 , the object should not be removed and the key with "0" value should also be there. 

i've tried splitting value and using conditions to check for 0 or null values but the problem with that is it removes all keys that have 0 values thus failing condition 2 for the code. 

       $vars = $data;
       $count = "";
       $finalArray = array();
       foreach ($vars as $keys => $values) {
         foreach ($values as $k => $v) {
           foreach ($v as $ke => $ve) {
                   if ($keys == "table6") {
                      $count = (array)$v;    
                      foreach ($count as $ck => $cv) {
                        if ($cv != "0")
                        {
                         $flag = true;
                         break;
                        }
                      }
             
             if($flag == false)
                  {
                    array_push($finalArray, $count);
                  }                         
           }
        }
     }
    print_r($finalArray);
    die();

I expeced the output to contain the objects with key value pairs that does not contain 0 value but everything prints here.

hi,

i actually got some code working to add an ID dynamically to a website i'm working on (it was a momentous occasion  ).

here's the code:
in the functions.php file:


$url = 'tanzaniatravel.za.com';
$page = $_SERVER['PHP_SELF'];
$page = str_replace("/","",$page);
$page = str_replace(".php","",$page);
$page = str_replace("$url", "", "$page");


i call the functions.php file into the index.php file, and add this as the opening body tag:

Code: [Select]
<body id="<?php echo $page; ?>">
this dynamically adds an ID named after whatever the actual page is named.

now, i make use of the following top navigation structu

Code: [Select]
<ul class="nav-top">
   <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a class="nav-top-lineheight" href="index.php" title="Tanzania Travel home">Home</a></li>
  <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a class="nav-top-lineheight" href="about.php" title="Why use TanzaniaTravel.Za.Com">Why us</a></li>
  <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a href="" title="">Overview and area map</a></li>
  <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a href="" title="">Tanzania National Park</a></li>
  <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a href="" title="">Tanzania Safari Lodges</a></li>
  <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a href="" title="">Tanzania Tour Itineraries</a></li>
  <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a href="" title="">Safari Dates &amp; Prices</a></li>
  <li <?php echo ($page == '' ? 'class="nav-top-current"' : ''); ?>><a href="" title="">Zanzibar Kilimanjaro</a></li>
  <li class="<?php echo ($page == '' ? 'nav-top-current' : ''); ?> nav-top-last-li"><a class="nav-top-lineheight" href="" title="">Contact Us</a></li>
</ul>

you'll see that i've left the $page variable empty. i want that variable to call in the current page's ID, so that only the current page's <li> is active. this, of course, will greatly assist with developing the CSS for the navigation.

i appreciate your help very much. thank you.

Hi,

I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads.  Here is uploadify.php as it currently looks:

Code: [Select]
<?php
session_name("MyLogin");
session_start();

$targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root

if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name'];

// Validate the file type
$fileTypes = array('m4a','mp3','flac','ogg'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);

if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}

echo $targetFolder;

?>
I added Code: [Select]
echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'.  For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'.  The folder for username exists, with correct permissions, and when I manually enter Code: [Select]
$targetFolder = '/songs/nick';all works fine.  Which strikes me as rather strange.  I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string.

Any help would be much appreciated.  It's the last issue with a website that was due to go live 2 days ago!

Thanks,

Nick
