PHP - Chrome, Random Image

I have a very simple piece of code to create a grid based gallery. The thumbnails are loaded from a single directory and are name 1.jpg... 2.jpg... 3.jpg etc

At the moment the images appear to be loaded in randomly. I want them to load in numerically in terms of their filename. I know I may need to use 'sort' or 'natsort' but where in the code?

Thanks for any help you can give me

Code: [Select]
<?

$images = "Images/Bag Thumbs/"; # Location of small versions

$big    = "ruxxwomens.php?id="; # Location of big versions (assumed to be a subdir of above)

$cols   = 4; # Number of columns to display

if ($handle = opendir($images)) {
   while (false !== ($file = readdir($handle))) {
       if ($file != "." && $file != ".." && $file != rtrim($big,"/")) {
          $files[] = $file;
       }
   }
   closedir($handle);
}



$colCtr = 0;
echo '<table width="800" cellspacing="0" cellpadding="0" border="0"><tr>';
foreach($files as $file)
{
  if($colCtr %$cols == 0)

    echo '</tr><tr>';

  echo '<td align="center"><a href="' . $big . $file . '"><img src="' . $images . $file . '" cellspacing="0" cellpadding="0" border="0"></a></td>';

  $colCtr++;
}
echo '</table>' . "\r\n";

?>

My images generator comprises an array of image names extracted form an images table from a database using a select statement a random number generator, and a string that builds the correct pathname for the selected file. To select one of the images for display, i generate a random number between 1 and the length of the array. Though the generator is working, I noticed one of the random numbers is throwing up this error: Warning: getimagesize(images/): failed to open stream: No such file or directory in An inspection of the array reveals 2 array elements (representing my number of images) but one array element is NULL ( the first entry in the banner table   image_generator.php

require_once('connection.inc.php');
    $sql = 'SELECT `filename` FROM  banner';
    $result = $mysqli->query($sql, MYSQLI_STORE_RESULT) or die(mysqli_error());
    $row = $result->fetch_array(MYSQLI_ASSOC);//an array of image names
    $count = $result->num_rows;
    for ($i = 1; $i <= $count; ++$i) 
    {
       $row[$i] = $result->fetch_array(MYSQLI_ASSOC);
    }
    $i = rand(1, $count); //a random number generator,
       //The random number is used in the final line to build the correct pathname for the selected file.
       $selectedImage = "images/{$row[$i]['filename']}"; 
      if (file_exists($selectedImage) && is_readable($selectedImage)) 
      {
        $imageSize = getimagesize($selectedImage);
      }

var_dump($row)

array (size=1)
    'filename' => string 'ginsomin2.jpg' (length=13)
    null

RANDON IMAGE DISPLAY

require_once 'image_generator.php';
<div id="banner" class="wrapper clearfix">
      <img src="<?php echo $selectedImage; ?>" alt="banner">
   </div>

Kindly advice how i may proceed from here? Thanks.

As above,

I have a lottery style site that picks a random number between 1-8 but my users complain for some reason that this is not enough.

So i was told to look into using fopen and random.org to generate a random number.

Anyone have experience of this and perhaps a code snippet for me to look at and possibly use?

help will be appreciated.

Chrome is the browser I use, I have it set up so that the script detects safari and chrome as separate entities. When I browse to it, it shows:

You are using Windows XP with a Chrome Web Browserwith a Safari Web Browser

now I know stristr() is a case-insensitive version of strstr(), which will find the first form of a word in a string. The problem is that when I use it, the rest of the script doesn't work... it goes to the part as if nothing is there, and shows the text on the bottom. I can't figure out why. Can someone help me, is there a chrome/safari level of priority or am I just missing something?

I'm attempting to set up a script that will choose a "random" image from a directory and then place it in an article when it's posted. I currently have a php file that randomly assigns a picture on each refresh, however my employer wants the image to be static after posting. So I guess the short of my question is, what would be the best way to go about something like that or is it even doable with PhP.

Is there a Chrome tag like this IE one

<!--[if IE]>

<![endif]-->

<!--[if !IE]><!-->
       
 <!--<![endif]-->

I have use the above tag in my wordpress site, and the only browser it doesn't work in is Google Chrome.

Hey everyone,

I haven't been working with php long and that my be the root of the problem here but your help is very appreciated. Here is the problem:

I have created a login system for a website everything seems to be working great in Chrome and FF. However IE8 is giving some problems. It acts as if my $username and $password variables don't get set. However, I have tried using echo and they print out just fine. I have tried rearranging my code and checking  the variables with inset() ...nothing I try seems to work. Maybe I'm doing something wrong you guys can help with. Thanks. (Code below)


Code: [Select]
<?php
session_start();
 // Connect to database code here (left out for obvious reasons)
******
******



//get user name and password before we try and connect
$username = $_POST['username'];
$password = $_POST['password'];


//if username and password suck go back to login screen otherwise check against database.
if(!$username && !$password)
{

header( 'refresh: 2; url=login.html' );
die("username and password could not be verified");

}
else
{
    ////here is where i would check database =p
}
....... 

Hi, I'm not sure where the problem is here. Right now this site works fine in IE and FF, but then I try to load data from the database into the cart, it get's screwed up in Chroms and Safari.   FF loads

<img src="inventory_images/11.jpg" alt="Some item" id="11" class="cartImages" border="1">

While Chrome loads this

<img src="inventory_images/url(http://localhost/Online/inventory_images/11.jpg).jpg" alt="" id="url(http://localhost/Online/inventory_images/11.jpg)" class="cartImages" border="1">

From this

if(isset($_POST['miniCartRequest'])){
	include "/storescript/connect_to_mysql.php";	

	$cartOutput = "";
	$cartTotal = "";
	$product_name="";
	$price="";
	if(!isset($_SESSION['cart']) || count($_SESSION['cart'])<1){
		$cartOutput  = "<h2 align='center' style='color:white;'>Your cart is empty</h2>";
	}
	else {
		
	$i = 0;
		
		foreach($_SESSION['cart'] as $each_item){
			
			$item_id = $each_item['item_id'];
			$sql =  $mysqli->query("SELECT * FROM products WHERE id='$item_id' LIMIT 1");
			while($row = $sql->fetch_array()){
				$product_name = $row['product_name'];
				$price = $row['price'];
				$details = $row['details'];
				$size = $row['size'];
				
			}
			
			$pricetotal = $price*$each_item['quantity'];
			$cartTotal = $pricetotal + $cartTotal;
			
			setLocale(LC_ALL, 'en_GB.utf8', 'en_GB');
			$pricetotal = number_format($pricetotal, 2);
			$x = $i + 1;
		
                      $cartOutput .= "<img src='inventory_images/" . $item_id . ".jpg' alt='" . $product_name . "' id='" . $item_id . "' class='cartImages' border='1' />";
	
			$i++;
		}
		
		
	}
	echo $cartOutput;
}

Can I create an alternative line of code specificall for Chrome/safari to remove the excess characters?
And why exactly are they reading the files with the full source locations vs firefox reading only the local location? It's completely unable to read the $product_name aswell. A bit strange, I take it those browsers process the specific information differently?

Not sure where in the forum to put this one.  Has any noticed when you use pagination with Chrome 18, it tries to display a link to the next page and display what it thinks is the next page?  It really shows the last page and is confusing to viewers. Is it possible to have Chrome ignore pages?

Yesterday I had this problem - I created this website in wordpress www.porthopehealthcentre.com
It displayed correct in firefox but not ie. There was an extra closing </div> tag in my header php. When I deleted it, it displayed correct in ie but not firefox.
So I added the below tag to my header.php file. It now displays correct in all browsers except google chrome, latest version.

What can I do to fix this so it displays correct in google chrome - anybody?
Thanks in advance - I really appreciate it.
