Hi experts,

I have an alphabetized table containing a lot of data to which I would like to add page numbers to (pagination). Here is the code as it stands:

<?php

     echo"<table border=\"0\"><tr>";
     foreach (range('A', 'Z') as $letter) {
        echo"<td><a href=\"rates.php?value=$letter\">$letter</a></td>";
     }    
     echo"</tr></table>";

      echo "<html><body><table>\n\n"; $f = fopen("rate.csv", "r");
      do{        

      if(strtoupper(substr($line[0],0,1)) == $_GET[value]){
          echo "<tr width=500>";        
          echo "<td width=200>" . $line[0]. "</td>";
          echo "<td width=100>" . $line[1]. "</td>";
          echo "<td width=100>" . $line[2]. "</td>";
          echo "<td width=100>" . $line[3]. "</td>";
          echo "<tr>";

        }
      }

      while (($line = fgetcsv($f)) !== false);
     
      fclose($f);

echo "\n</table></body></html>";

?>

Thanks

Well............ It's alive ! This is what I've done, the code needs a little adjustments but tell us if this is what you want:

<?php

     // THE ALPHABET
     echo"<table border=\"0\"><tr>";
     foreach (range('A', 'Z') as $letter) {
        echo"<td><a href=\"rates.php?value=$letter\">$letter</a></td>";
     }    
     echo"</tr></table>";

    // for counting
    $f = fopen("rate.csv", "r"); 
    
    // counter
    $i = 0;
    while($line = fgetcsv($f)){
        $array[$i][0] = $line[0];
        $array[$i][1] = $line[1];
        $array[$i][2] = $line[2];
        $array[$i][3] = $line[3];
        $i++;
    }
    
    // substract the head line from csv
    //$rows = $i - 1;
    $ipp = 2; // items per page
    
    fclose($f); 
    
    echo"<table>";
    
    if(!empty($_GET[value])){
    
        // remove the description line
        array_shift($array);
    
        $j = 0;
        foreach($array as $key => $value){
            // let's get the new array with only a specific letter
            if(strtoupper(substr($array[$key][0],0,1)) == $_GET[value]){
                $country[$j][0] = $array[$key][0];
                $country[$j][1] = $array[$key][1];
                $country[$j][2] = $array[$key][2];
                $country[$j][3] = $array[$key][3];
                $j++;            
            }
        }
        
        // j is the number of rows
        // pages
        $pages = ceil($j / $ipp);
        

        echo"<tr><td colspan='5'>";
        echo"number of pages for letter $_GET[value] is $pages<br />page: ";
        
            for($i = 1;$i<=$pages;$i++){
                echo"<a href=\"rates.php?value=$_GET[value]&amp;page=$i\">$i</a> | ";
            }
        echo"</td></tr>";  
        
        // get the current page
        if(empty($_GET[page]) || !isset($_GET[page])) $page = 1;
        else $page = $_GET[page];	
        
        $startitem = ($page - 1)*$ipp;
        $enditem = $startitem + $ipp;
        
        echo"$startitem to $enditem";
        
            // output the pages from array
            for($i = $startitem;$i<$enditem;$i++){
                  echo "<tr width=500>";        
                  echo "<td width=200>" . $country[$i][0]. "</td>";
                  echo "<td width=100>" . $country[$i][1]. "</td>";
                  echo "<td width=100>" . $country[$i][2]. "</td>";
                  echo "<td width=100>" . $country[$i][3]. "</td>";
                  echo "<tr>";             
                //echo"<a href=\"rates.php?value=$_GET[value]&amp;page=$i\">$i</a> | ";
            }        
        
    
    }
    else{
        foreach($array as $key => $value){
              echo "<tr width=500>";        
              echo "<td width=200>" . $array[$key][0]. "</td>";
              echo "<td width=100>" . $array[$key][1]. "</td>";
              echo "<td width=100>" . $array[$key][2]. "</td>";
              echo "<td width=100>" . $array[$key][3]. "</td>";
              echo "<tr>"; 
              }
    }
    
    echo"</table>";    
    

?>

$ipp = 2; // items per page

Thanks Roads, I will check it out in the morning and let you know. One other thing, the very first line in the .csv file is actually the headings for the columns in the table - any way that first line could be omitted altogether? It shows under D as the first heading is Destination. I can just add a <tr> with the headings instead. Thanks!
