Image gallery photo count.

[benson]

Hello,

I have this code

<?php
//begin code


echo "<div align=\"center\">";
echo "<table border=\"0\" cellspacing=\"1\" width=\"100%\">";
$dir = "upload/";

$num_columns=2;            // number of columns

// Open a known directory, and proceed to read its contents

echo "<table border=0 cellpadding=3 cellspacing=0><tr>";

if (is_dir($dir))
 {
    if ($dh = opendir($dir))
 	{
        $i = 0;
        while ($file = readdir($dh))
	 	{
            $strFile = $dir."/".$file;


    if(!is_dir($strFile))
	 {
        $i++;
        echo "<td valign=top>";
        echo "<a href=\"$strFile\" ><img src=\"$strFile\" alt=\"Druk voor plaatje\" border=0 width=\"200\"></a>";
        echo "</td>";            
        if(is_int($i/$num_columns))
		 {
            echo "</tr><tr>";
        		}
    	}
    	}
    closedir($dh);
	}
 }

echo "</tr></table>";
//end code
?>

This code puts ALL the images on the page.
i Want it to show 10 or 20 images per page and links to the other ones.
I searched the forums but everything was with Databases..

Help is needed,
Benson

i have used a similar script on www.cougarimage.com before..

however, it is much easier if you use a database.

but my script does it as you want... so here's the script I used... not 100% mine, but it works.

<?

$incldir="thumbs/";
$pagenum=$QUERY_STRING;

if ( $pagenum == NULL ) {  

  $pagenum=1;
}


$realpage=$pagenum - 1;
$linecount=0;

$d2 = dir($incldir);

while($entry=$d2->read()) {
    if ( $entry != "." && $entry != ".." && $entry != ".total" ) {
       $linecount++;
    }
}
$pagecount=$realpage * 10 + 1;
$endcount=$pagecount + 10;

$totalpages=floor($linecount / 10);
$rtotalpages=$linecount % 10;

if ( $rtotalpages >= 1 ) {
   $totalpages++;
}
//line 30
$currcount=1;

$d2 = dir($incldir);

while($entry=$d2->read()) {
    if ( $entry != "." && $entry != ".." ) {
      if ( $currcount < $endcount && $currcount >= $pagecount )






{
    echo "<a href=\"upload/${entry}\"><img src=\"thumbs/${entry}\" border=0></a>&nbsp;&nbsp;";
    }
    $currcount++;

}
}
echo "<br><Br>";
$back=$pagenum - 1;
$next=$pagenum + 1;

if ( $back < "1" ) {
  echo "&nbsp;&nbsp;";
} else {
  echo "<A href=\"".$PHP_SELF."?$back\">&lt;&lt;</a>";
  echo "&nbsp;";
}

$totalpagecount=1;

while ( $totalpagecount <= $totalpages ) {
   if ( $totalpagecount == $pagenum ) {
      echo "<b>$totalpagecount</b>&nbsp;";
   } else {
      echo "<a href=\"".$PHP_SELF."?$totalpagecount\">$totalpagecount</a>&nbsp;";
   }
   $totalpagecount++;
}


if ( $next > $totalpages ) { 
  echo "&nbsp;&nbsp;";
} else {
  echo "<A href=\"".$PHP_SELF."?$next\">&gt;&gt;</a>";
}

?>

I found the script somewhere (credit to whomever made it 😉 ) and I added a few things here and there.. and fixed a few bugs in it. works great now... however, with this it is important that you do not put the pictures in a table.

if you havea ny problems with the $PHP_SELF, just change it to yourpage.php instead.

also, i used a variation of this script to insert my images on cougarimage.com into a database and it made everything alot easier... so that's my suggestion to you if you know database's

good luck

Hello,
Ain't it possible to convert your code to a code were i can use tables in ??
My reason to not use databases is that i find the code difficult to understand..
But if necesary i will switch to database.

Thanx for your code...

it's possible, not really too hard.

you need a few counters in the while statement and you set one up to how many images you want across.

but ti's the same coding as for database's really, after you have pulled the info anyway.

MySQL is very easy to understand if you have knowledge of PHP, i have learned alot of both in about 6 months now.
