doogi · #1 (**permalink**) 06-10-03, 01:52 PM

Hi there

it's my first thread here so first i'd like to say hello to everyone

i have pictures with links to other sites on my page. After each reloading script shows 5 random pics with links.
I have 3 tables with 5 pics on my so 15 pics is used at one time. i have a 45 pics in a txt file which can be teken by script.
My problem is that i have 2 or even 3 same pics after each reloading. what can i do to have no doubled pics?
the scripts looks like below:
<?
$ile = 5;
$file = file("pics.txt");
echo "<table width=\"600\"><tr>";
for($i=0;$i<$ile;$i++)
{
srand((double)microtime()*1000000);
$link = $file[array_rand($file)];
$sp = explode("||", $link);
if($sp[0]<>"")
{
echo "<td align=middle><a
href=\"".$sp[2]."\"><img src=\"".$sp[0]."\" border=3></a> ".$sp[1]." </td>";
}
}
echo "</tr></table>";
?>

Help me pls

Hm...
First thing.

If you have to put PHP code, put it between [ PHP ] and [/ PHP ] (without spaces) so it will be color coded! see my code below!

PHP Code:


			
<?

    

    srand((double)microtime()*1000000);

    $ile = 5;

    $file_names = file("pics.txt");

    echo "<table width=\"600\"><tr>";

    

    $picked_file = array_rand($file_names,5); //Ask it to pick 5 random entries!

    foreach($picked_file as $file)

    {

        $link = $file_names[$file];

        $sp = explode("||", $link);

        if($sp[0]<>"")

        {

            echo "<td align=middle><a href=\"".$sp[2]."\"><img src=\"".$sp[0]."\" border=3></a><br>

            <font style=\"font-weight: bold; font-size: 11px; font-family: Tahoma\">".$sp[1]."<br></font></td>";

        }

    }

    echo "</tr></table>";



?>

See if the code solves your problem!

JD

PHP Code:


			
<?php



$ile  = 5;

// I used this line to test it

// $file = array(1,2,3,4,5,6,7,8,9,0);

$file = file('pics.txt');



echo '<table width="600"><tr>';

echo "\n";



srand((double)microtime()*1000000);

$link = array_rand($file, $ile);



for($i=0; $i<$ile; $i++)

{

    $sp = explode('||', $link[$i]);

    if($sp[0] <> '')

    {

        echo '<td align=middle>';

        echo "\n";



        echo '<a href="'.$sp[2].'"><img src="'.$sp[0].'" border=3></a><br>';

        echo "\n";



        echo '<font style="font-weight: bold; font-size: 11px; font-family: Tahoma">'.$sp[1].'<br></font>';

        echo "\n";



        echo '</td>';

        echo "\n";

    }

}



echo '</tr></table>';

echo "\n";



?>

I think that should work.

Edit: Ah, phpkid already replied

Thanks for your support guys

phpkid - it works fine but only in one table /in one table i don't have doubled images with links anymore/ but still i have same pictures in second or third table from time to time /i mean that pics for example 1.jpg is never doubled in one table but can be again in others tables in the same time.

Cagez - i filled my page with your script but it looks that script takes nothing from txt file, <a href=""> - no link taken and <img src="11" border=3> - number taken but extension .jpg not.
sample below:
<table width="600"><tr>
<td align=middle>
<a href=""><img src="11" border=3></a> 
 
</td>
<td align=middle>
<a href=""><img src="15" border=3></a> 
 
</td>
<td align=middle>
<a href=""><img src="20" border=3></a> 
 
</td>
<td align=middle>
<a href=""><img src="46" border=3></a> 
 
</td>
<td align=middle>
<a href=""><img src="48" border=3></a> 
 
</td>
</tr></table>

what to do now?

i hope that you understood what i mean, i'm asking beacuse sometimes i don't understand myself

regards

PHP Code:


			
<?php



$ile  = 3;

// I used this line to test it

// $file = array(1,2,3,4,5,6,7,8,9,0);

$file = file("pics.txt");



echo '<table width="600"><tr>';

echo "\n";



srand((double)microtime()*1000000);

$keys = array_rand($file, $ile);



for($i=0; $i<$ile; $i++)

{

    $sp = explode('||', $file[$keys[$i]]);

    if($sp[0] != '')

    {

        echo '<td align=middle>';

        echo "\n";



        echo '<a href="'.$sp[2].'"><img src="'.$sp[0].'" border=3></a><br>';

        echo "\n";



        echo '<font style="font-weight: bold; font-size: 11px; font-family: Tahoma">'.$sp[1].'<br></font>';

        echo "\n";



        echo '</td>';

        echo "\n";

    }

}



echo '</tr></table>';

echo "\n";



?>

Doh! I was using array_rand wrong

This should work now.

I would have a file called 'links.txt' that contains:

Code:

http://www.yoursite.com|/path/to/image.jpg|This is the alt info
http://www.yoursite.net|/path/to/image.jpg|This is the alt info

and a php file 'links.php' that contains this code:

PHP Code:


			
<?php



$file = file_get_contents("./links.txt");

$line = split("\n", $file);



foreach ($line as $l) {

    $text = split("\|", $l);

    print "<a href=\"$text[0]\"><img alt=\"$text[2]\" src=\"$text[1]\" border=\"0\"></a>";

}



?>

Thats all you need, apart from a layout to include 'links.php' into.

No, that would get each image out of the file, he only wants 5, and to get them randomly.

doogi · #9 (**permalink**) 06-11-03, 03:57 PM

same again

it shows pictures now but doubled again.
i'm not sure if i explained well what i mean, so again:

5 random pictures from pics.txt file

something else , other links and so on

5 random pictures from pics.txt file

something else , other links and so on

5 random pictures from pics.txt file

something else , other links and so on

that's like my page looks like and i want no picture doubled on a page

after every script i tried i always have some pictures doubled, not in one line but in one page
so i wonder if it's possible or only my wishes

So, for example, accross 3 pages you want random images on all of them without duplicated on any?

Hm, thats a little more difficult... You have to track which ones the user has seen and which s/he hasnt.
