Im new to the forums here but was just wondering if there is any chance of being able to look at the code? im looking for something similar to this but all the examples i have found online are for only displaying 1 random image at time...

Cheers Ezy

<?php
	$arr=array();
	for($i=0;$i<7;$i++){
		$arr[$i]="./img/images/".$i.".jpg"; //assigning the image location to the array $arr.
	}
	$random=rand(0,6); //generating a random number
	echo "<img src=".$arr[$random].">";
//printing the image
?>

Thats it :)

[somedude3488]

i think ezykiwi wanted to display more than one image. your code only displays one random image.

[nav33n]

if thats the case, why not generate one more random number ?

<?php
	$arr=array();
	for($i=0;$i<7;$i++){
		$arr[$i]="./img/images/".$i.".jpg";
	}
	$random=rand(0,6);
	$random_1=rand(0,6);
		echo "<img src=".$arr[$random].">";
		echo "<img src=".$arr[$random_1].">";
?>

This will do.. Don't you think ?

[ezykiwi]

that looks like it could do the trick with abit of working... basically....

i want there to be a folder of images... the names of those images could be anything at all.... number letters.. mixtures... there will be no logical order to them..... i just need the code to randomly pick say 10 images... out of that folder... no image being displayed twice etc...

if there isnt enough ... say there is 4 images.. it will just display 4

if there is no images... maybe just a statement showing there is no images to display at this time...

Hi, I am fairly new to web design and am trying to do exactly what you helped the other person on this post do, is there any way I could also get ahold of that code? I would be very grateful. Thanx.

Hi,

I am new to Php. Iam unable to write a php code for random images on a webpage that displays new image each time it is refreshed. Im having images in a folder in my college FTP. Can any one post a code for me in Php ? Coz im unable to make the changes to my php file....

[angelic_devil]

plz post the script so that we understand what u did

[somedude3488]

This is something I just typed up. Not the same as the one I get to the other poster, but close.

It will read a folder and get the images. Then randomize them and display in a paginated form.

<?php

session_start();

$thispage = 'image.php';
$imageDir = 'icons/';
$perPage = 10; //total images to display per page
$perRow = 2; //total images per row

if ( isset( $_GET['reset'] ) ) {
	unset( $_SESSION['chunks'] );
}

if ( !isset( $_SESSION['chunks'] ) ) {
	if ( is_dir( $imageDir ) ) {
		if ( $dir = opendir( $imageDir ) ) {
			while ( ( $file = readdir( $dir ) ) !== false ) {
				if ( $file !== '.' && $file !== '..' ) {
					$images[] = $file;
				}
			}
			closedir( $dir );
		}
		else {
			die("Unable to read directory - {$imageDir}");
		}
	}
	shuffle( $images );
	$_SESSION['chunks'] = array_chunk( $images,$perPage );
}

$page = 1;
if ( isset( $_GET['page'] ) && $_GET['page'] > 0 ) {
	$page = (int) $_GET['page'];
}

$chunk =& $_SESSION['chunks'];
$total = count( $chunk );
if ( isset( $chunk[$page-1] ) ) {
	$images = $chunk[$page-1];
	$html = "<table cellspacing=\"0\" cellpadding=\"3\">\n\t<tr>\n";
	$i = 0;
	foreach( $images as $image ) {
		if ( $i == $perRow ) {
			$html .= "\t</tr>\n\t<tr>\n";
			$i = 0;
		}
		$html .= "\t\t<td><img src=\"{$imageDir}{$image}\" /></td>\n";
		$i++;
	}
	$html .= "\t<tr>\n";
	if ( $total > 1 ) {
		$nav = '';
		if ( $page > 1 ) {
			$nav .= "<a href=\"{$thispage}?page=1\">[FIRST]</a><a href=\"{$thispage}?page=" . ( $page - 1 ) . "\">[PREV]</a>";
		}
		$i = 1;
		while( $i < $total + 1 ) {
			$nav .= "<a href=\"{$thispage}?page={$i}\">[{$i}]</a>";
			$i++;
		}
		if ( $page < $total ) {
			$nav .= "<a href=\"{$thispage}?page=" . ( $page + 1 ) . "\">[NEXT]</a><a href=\"{$thispage}?page={$total}\">[LAST]</a>";
		}
		$html .= "\t<tr>\n\t\t<td colspan=\"{$perRow}\">{$nav}</td>\n\t</tr>\n";
	}
	$html .= "</table><br /><br /><a href=\"{$thispage}?reset=true\">Shuffle Images</a>";
	echo $html;
}

?>

Hi..kkeith29
How can we make the image click able ?
wrt line 48 in your code

$html .= "\t\t<td><img src=\"{$imageDir}{$image}\" /></td>\n";

I tried

$html .= "\t\t<td><a href="MYSITE.com/?v={$image}"<img src=\"{$imageDir}{$image}\" /></td>\n";

But I got error..
can you please help me to make the images displayed clickable in this format
mysite.com/?v={$image}

Thanks :D

[somedude3488]

Replace

$html .= "\t\t<td><img src=\"{$imageDir}{$image}\" /></td>\n";

with

$html .= "\t\t<td><a href=\"http://www.mysite.com/?v={$image}\"><img src=\"{$imageDir}{$image}\" /></a></td>\n";

Thanks :)

Can I put this in an asp.net page?

I'm not sure where to put this php code.. ? Sorry

[sajjadhira]

Use simple function.

function RandImg($dir)
{
$images = glob($dir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

$randomImage = $images[array_rand($images)];
return $randomImage;
}

$the_image = RandImg('images/tips/');
echo $the_image;

[Gi]

is it possible to add alt text to each image randomly choosed from a single txt file where it has multiple texts line per line?

[cereal]

@Gi

What do you mean by multiple texts line per line? Can you share an example? Also, it would be a lot better if you start your own new thread.
