Hi all am am trying to reduce duplicated elements in a php page. How can I create a function that will pass the different values in the array.

Thanks in advance

       for ($i=$index-$x+1; $i<=$index; $i++)
           {
               echo "<div class='partner_description' id='partner_description_" .$partners_id[$i]. "'>";
                echo "<p>".$description_value[$i]. "</p>";
                echo "<div class='url'>";
                echo "<a href='http://".$url_value[$i]."' target='blank'>".$url_value[$i]." </a></div>";
                echo "</div>";
            }

Hi Pritaeas The echo statments are from the db but where the value differ is in the duplicatation side is passing data for loop($i=$index-$x+1; $i<=$index; $i++)

This is the first call to the for loop

   for ($i=$index-4; $i<=$index; $i++)
       {
          echo "<div class='partner_description' id='partner_description_" .$partners_id[$i]. "'>";
          echo "<p>".$description_value[$i]. "</p>";
          echo "<div class='url'>";
          echo "<a href='http://".$url_value[$i]."' target='blank'>".$url_value[$i]." </a></div>";
          echo "</div>";
       }

and this is the second use of the for loop

for ($i=$index-$x+1; $i<=$index; $i++)
           {
               echo "<div class='partner_description' id='partner_description_" .$partners_id[$i]. "'>";
                echo "<p>".$description_value[$i]. "</p>";
                echo "<div class='url'>";
                echo "<a href='http://".$url_value[$i]."' target='blank'>".$url_value[$i]." </a></div>";
                echo "</div>";
            }

As you can see the two are identical except for the for
loop syntax for ($i=$index-$x+1; $i<=$index; $i++)

I am looking to get away from the repetive use of code.

Thanks in advance

Oh, just put that code in a function, and turn the variables into parameters:

function partnerDescription($partner, $description, $url)
{
    $result = "<div class='partner_description' id='partner_description_{$partner}'>";
    $result .= "<p>{$description}</p>";
    $result .= "<div class='url'>";
    $result .= "<a href='http://{$url}' target='blank'>{$url}</a></div>";
    $result .= "</div>";
    return $result;
}

Call it inside the loop like this:

echo partnerDescription($partners_id[$i], $description_value[$i], $url_value[$i]);

Hi Pritaeas thanks for thew great solution it was very much appreiciated. Just one other question on functions based on the following validation method:

If I were to collect the following data via request and pass this through a function would I need to declare this as a global variable? or change this if (!isset($_REQUEST['partner_name']) to if (!isset(partner_name)

Thanks in advance

D

if (isset($_REQUEST['partner_name']))
             $partner_name_error=($_REQUEST['partner_name'])


<?php
    function partnererror($partner_error)
        {
           if (isset($partner_error) && isset($_REQUEST['submit']))
              {
                 if (!isset($_REQUEST['partner_name']) ||  empty($_REQUEST['partner_name']))
                          {
                              $partner_error = "Please enter a partner name";
                              echo "<span class='mandatory'>".$partner_error."</span>";
                           }
              }
       }
 ?>
