Identifying Black Images
I would like to be able to identify completely black images in order that I can exclude them. I am thinking I could use gdlib but I cannot find a suitable function. If I can find the rgb of the image then I can exclude it.

First of all i've VDS Server so i can change any settings in PHP or Apache so all comments are welcomed... I am running a web site where users can upload images and its been online for 4 months and going well, but suddenly i discoverd that when uploading a picture that is about 1 MB 800x530 pixels or other which is 464 KB 1600x1200 pixels, then my script cant read their height and width then i get invalid dimensions and the image dont get resized at all and stays at their original width & height which breaks the page design! and this is when i was using: imagesx(); imagesy(); but i got the dimensions using "getimagesize()" and it was resized correctly but both images turned black! So where could be the fail! Please help me urgently because i think am losing users, i dono how come i didnt test big images b4 going live :( Here is the part where the fail & warnings come! if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) { $info = getimagesize($uploadfile); $width = $info[0]; $height = $info[1]; $type = $info[2]; $attr = $info[3]; $image = "$uploadfile"; $newimage = "$uploadfile"; $image_quality = 75; $addborder = 0; $max_height = 480; $max_width = 640; // Main code switch( $info['mime'] ){ case 'image/jpeg': $src_img = @imagecreatefromjpeg($image); break; case 'image/gif' : $src_img = @imagecreatefromgif($image); } $orig_x = $width; $orig_y = @imagesy($src_img); if($width > 640 ¦¦ $height > 480) { $new_y = $max_height; $new_x = $orig_x/($orig_y/$max_height); if ($new_x > $max_width) { $new_x = $max_width; $new_y = $orig_y/($orig_x/$max_width); } $dst_img = @imagecreatetruecolor($new_x,$new_y); @imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $new_x, $new_y, $orig_x, $orig_y); } else { $dst_img = @imagecreatetruecolor($width,$height); @imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $width, $height, $orig_x, $orig_y); } @imagejpeg($dst_img, $newimage, $image_quality); @imagedestroy($src_img); @imagedestroy($dst_img); $_SESSION["img"] = "$uploadfile"; $formVars["userfile"] = "$uploadfile"; $img = "$uploadfile"; if($width > 640 ¦¦ $height > 480) { $_SESSION["x"]="$new_x"; $_SESSION["y"]="$new_y"; } else { $_SESSION["x"]="$width"; $_SESSION["y"]="$height"; } }

Why Are My Images Coming Out As Black Jpegs?
I've written a script to create thumbnails of my images. Here is my code: list($width, $height) = getimagesize($filename); $new_height = 100; $new_width = ($new_height / $height) * $width; $image_p = imagecreate($new_width, $new_height); $image = imagecreatefromjpeg($filename); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height); imagejpeg($image_p "images/thumbs/1.jpg", 100); When I look at images/thumbs/1.jpg it's just a blank image. Anyone have any ideas why this would happen and how I can fix it?

The problem I have is stopping session hijacking.

Identifying An Image
Ive got a tracking system which tracks how many times a user clicks on an advert on my site. At the moment all the listings are set as one so when a user clicks on that advert it gets one click. However, one of the adverts is now going to contain two images advertising two separate companies. Ive set it up so the images and urls are different and they go to their own websites and in my tracking table i have just added an extra column called image and the number 1 goes in if image 1 is clicked on or 2 if image 2 is clicked on. However, to display this is the bit im not sure about. At the moment its displayed in a table like this: Advert Name Category Number of clicks Advert 1 Shopping 257 However, if advert 1 has two images, meaning two separate companies, how can I show this in the above table?

Identifying Search Engines

(especially google) would search engines ignore the keywords if they are inside javascript tags? how do i detect search engines? maybe i can just setup a special script that output's "search-engine-friendly" output.

Identifying Dynamic Form Fields
User goes to page which is a form that asks for some basic info regarding returning products for credit/exchange, and also asks for how many products are going to be returned. Upon submitting, a return authorization form is presented to them with the specified number of product fields. I now want to take the input from this form and email it to myself, as well as, display a confirmation page to the user. The problem I have is a can't say, for instance, echo "$field_name"; because field_name will get created dynamically after the user specifies how many products to return. For example, say the user says 5 products, this will generate a form with field names like: return_code0 inv_num0 qty0 product0 cre_exch0 stockout0 return_code1 inv_num1 qty1 product1 cre_exch1 stockout1 return_code2 inv_num2 qty2 product2 cre_exch2 stockout2 and so on.... These get created with a for() loop. Once this form is submitted, how can I address the field names? Code:

Identifying Non-Supported Characters In A TTF File With GD?
I've managed to get GD working (mostly anyway) on my site - and am utilising the "imagettftext" function. I am using this function to display individual characters on my website - with a nominated Font. However, sometimes the characters in my StringText are not supported by the particular font that I am using ... Directly from http://www.php.net/manual/en/function.imagettftext.php imagettftext - "If a character is used in the string which is not supported by the font, a hollow rectangle will replace the character." Can anyone suggest some code that would: 1) compare/look at the StringText supplied within the "imagettftext" function (in my case the StringText will comprise of a single character only) 2) where the supplied StringText (ie character) is NOT supported by the font, then I need for that character to be reported as not supported. ie. either; return a flag or skip the non-supported character entirely - rather than displaying the standard "hollow rectangle".

Identifying Opening Link For Database Query?
I've got a tricky problem i need to solve, i'm building a banner exchange type site in which there are already about 100 banners so i've had to code things around what already exists to a certain extent. Now each of the banners that go out on other sites have a link on the banner which pops open a window with details of the banner. this would be fine if all my banners were gifs and jpgs but there are also swf and dcr banners so i have no real control over the actual link on the banner. up until now each banner had a html page made for it so when you clicked on a banner it would open a page banner_1.html which had the details of that banner. for obvious reasons i'm going to replace all these redundant pages and put a htaccess redirect at their url to all redirect to a common page popup.php so all details will be dealt with in one file. ok this is fine but my problem is in this page popup.php i need to identify the link that just opened the window so that i can then get the info from the database to put on the page.. remember i can't use the url like so... bannerpage.php?thisbanner=1 but all existing links have unique addresses, is there a way to do this, i'm pretty sure there must be but i can't get my head around it?

Identifying User's Pick From Selection List
I have an application that uses PHP to access a MySQL table and extract rows which match the user's search entry. Data from the matching rows are loaded into an HTML selection list, and the user can scan the list and highlight a selected item. My question: In PHP, what is the syntax for identifying which row is highlighted? My goal is to pass the unique row ID of the selected item to a subsequent form where all the fields will be displayed for the user to edit. I already have the code that loads the selection list and the code that displays the fields. I just need to know how to determine the highlighted item. I have two PHP books, and both discuss loading the selection list, but there is no mention of what to do next.

Form, Type=file And Identifying By Isset()
Windows XP PHP 4.4.2 Apache 2.2 Register_Globals = Off Safe_Mode = On ----------------------- Hi All, I am having a problem getting a file browse input field to be recognized on the next page. Let me show you... page1.php Contains a web form with a file input to attach a file using a browse button. <form method='POST' action='page2.php' enctype='multipart/form-data'> <input name='uploadFile1' type='file' id=uploadFile1'> page2.php contains a validator to check the input and perform an action based on whether or not the browse input field has been populated. // IF THE POST CONTAINS A FILE UPLOAD, PROCESS SECTION 1 IF NOT PROCESS SECTION 2. if (isset($_POST['uploadFile1'])) { echo "File is attached so print this."; } if (!isset($_POST['uploadFile1'])) { echo "File is NOT attached so print this."; } If the user uses the browse button on the form page to populate the field with a file path to a file on his pc, then I expect to see the "File is attached message". However, regardless of whether someone does or does not browse a file, the message is always that they have NOT browsed a file and the variable "uploadFile1" is effectively left unpopulated. OUTPUT File is NOT attached so print this. Conversley, I thought I might be able to use the _FILES variable instead of _POST, but I get the exact opposite, that the browse field is populated all the time whether or not someone has browsed a file or left the browse field blank. if (isset($_FILES['uploadFile1'])) { echo "File is attached so print this."; } if (!isset($_FILES['uploadFile1'])) { OUTPUT File is attached so print this. So, I am missing something. Can someone give me some direction so that I can simply identify (with register_globals = Off) whether or not an input field (input type=file) has been populated or left blank? Is this even possible? What am I missing?

Black Hat Or Not? Linking Technique Using PHP
I had an idea that I wanted to see what people think of it. I'm optimizing a site that is already built w/ very generic file naming and directory structure. In other words, I don't have directories or file names that intentionally have keywords in them. For the most part, its just a lot of index.php and one-word names. So now I'm trying to figure out a way to get some keyword URL's in there w/o trashing my directory structure. Here's what I'm thinking: Let's say I have a link already in the page that goes to index.php. What if I changed the link to keyword_term.php, then I put the following code in keyword_term.php: <?php $no_spider = "TRUE"; include "index.php"; ?> index.php would then have this in the header: <?php if ($no_spider = "TRUE") { echo "<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">"; } ?> I know it seems like more work than its worth, but the idea is that in the long run, I can optimize multiple pages for different keywords, while requiring little maintanence if I decide to edit the original index.php. I'm also using the $no_spider variable to aviod being penalized for duplicate content. My intention is not to get index.php indexed multiple times, just to allow other pages to link to it using different file names.

Strange Black Lines
I've got an image resizing tool that I've adapted from one I've used before (which worked) and I'm having a few issues with it. The thumbnails generated are either squashed but look normalish OR the right size but with the black background from the imagecreatetruecolor function used. My code is: PHP Code: $im = @imagecreatefromjpeg($image); // Changes the image from a file path to an image resource. $type = @getimagesize($image); // Sets the image type. //$height = $type[0]; //$width = $type[1]; $height = imagesy($im); $width = imagesx($im); $imgw = 150; // Sets the width of the thumbnail $imgh = ($height / $width) * $imgw; //$imgh = round(($height / $width) * $imgw); $thumb = @imagecreatetruecolor($imgw,$imgh); // Creates blank thumbnail @imagecopyresampled($thumb, $im, 0, 0, 0, 0, $imgw, $imgh, $height, $width); // Copies main image into thumbnail. // Displays the resized image......................

Cropping Black Section
I am doing this sequence: $image_rsz = imagecreatetruecolor($width, $height); $image = imagecreatefromjpeg($UploadName); imagecopyresampled($image_rsz, $image, 0,0,0,0, $final_width, $final_height, $width_orig,$height_orig); and uploading the resized image. The resizing looks right, but the JPEG file has a black section appended to the right of the image that is the same height as the resized image, but about 2 1/2 times the width of the picture. Is there something that needs to be done to crop off this excess? The original image, prior to resizing, did not have this.

Identifying Different Unicode/utf-8 Types Inside A Text String
I am dealing with a script that reverses a string that is in hebrew, so I can display it properly when I write that string onto an image, however sometimes the string might be half hebrew half english, so I need a way to identify what language is in the string and only reverse the hebrew parts. in technical terms the hebrew text is encoded in utf-8, and the english text will be encoded in the normal encoding for english, (anscii, latin-swedish whatever, i dont know the name of that encoding) so the simple question is how do I identify different types of encoding within a string? that way I can break up the parts that i identify as being utf-8 and reverse only those (yes I am well aware of methods to display hebrew properly in php, but when writing to an image this is another story, only method i found so far is reversing the hebew text string)

GD Imagecopy Problems With Black Background
This function is part of a class, it basically creates a new image in the dimensions specified, and then copies in the image held in $this->image. The image that is copied in will never be bigger than the new image (that is taken care of in another function) but one or both of the dimensions could be less than the new image (if the ratio isn’t the same). It all works perfectly, it creates a new true colour image, fills it in white, but then when it runs the imagecopy function it seems to forget the fact that I set the background to white, and the image that results has a black border. For example if I wanted a 100x100 image, and I was copying a 100x50 image in, I would end up with a 100x100 image with the old image centred vertically and a 25px black stripe above and below, I want those stripes to be white. Any ideas? function crop($width = null, $height = null) { // get the current widths and heights $current_width= imagesx($this->image); $current_height= imagesy($this->image); $crop_top = floor(($current_width - $width) / 2); $crop_left = floor(($current_height - $height) / 2); // create a new image resource $temp= imagecreatetruecolor($width, $height); $white= imagecolorallocate($temp, 255, 255, 255); imagefill($temp, 0, 0, $white); // copy image into new resource imagecopy($temp, $this->image, 0, 0, $crop_top, $crop_left, $width, $height); // destroy original image imagedestroy($this->image); // copy new image $this->image = $temp; }

Imagecreate Output A Solid Black Image
I'm making thumbnails. I want to first scale down the image before I crop it even smaller. The code below only creates a solid black square. Actually, only $final_im creates an image that's solid black. If I used $im as the output file (if I use this instead: imagejpeg($im, "$new_name") ), it's fine (albeit a very low quality image that does not have the dimensions I desire). I figure the problem lies at the //create final thumbnail section of the code. But, again, everything looks right. I would try other functions like imagecopyresizedbicubic , or imagecopyresampled but my server is using an older GD version, and I cannot upgrade it (ISP's server). PHP Code:

PHP (GD) Created Transparent PNG: AlphaImageLoader Makes Black Parts Transparent Instead Of Transparent Color Set With PHP

It seems that the AlphaImageLoader works correctly on a PNG image that has been created with an image processor and then uploaded, but not with a PNG image created with PHP. It seems to ignore the transparent color set with PHP and instead to render the black color transparent. The image in question was created using this code: <?php $source = imagecreatefrompng("parrot_orig.png"); $transp = imagecolorallocate($source,255,0,0); imagecolortransparent($source,$transp); imagefilledrectangle($source,15,15,70,70,$transp); imagepng($source,"parrot_php.png"); ?> The HTML used on the page is this:

I am putting together an image gallery using open source code. I have a script to generate thumbnails but it is not ideal because the quality loss from the original images is high. Secondly, ideally i would like the portrait images to resize to the same size as landscape images but i am not sure how to achieve this.
