Problem with OpenCart and Pagination

[Bravat]

I had to create a custom search for OpenCart (with multiple drop down lists), and now i need to create a custom pagination. Code is working fine until i click next or page number, then I get errors (it is the same like when you go directly to search page without submitting search query (Undefined index: Rim in... and it list all the indexes)).

 

This is part of the drop down lists:

<form id="form1" name="form1" method="post" action="index.php?route=product/search"> 


            <input type="text" value="keyword" id="filter_keyword" name="keywords" onclick="this.value = '';" onkeydown="this.style.color = '000000'" style="color: #999;width:154px;">
  

            <?php
            $result = mysql_query("SELECT *
FROM product
GROUP BY Rim");
            ?>
            
  <select id="Rim" name="Rim"  selected="selected" style="width:158px;position:static;z-index:-1;">
  <option value="rim" selected="selected"><?php echo "Rim"; ?></option>

<?php

while ($row = mysql_fetch_array($result)) {
  echo "<option>" . $row['Rim']  . "</option>";
  echo "<br />";
  } ?>
  
       </select> 
.....
<input type="submit" name="Kreni"  value="Pretrazi" />

 

and this is  pagination part (where search is routed):

$per_page = 4;
   if(isset($_POST['Pretrazi'])){
   $start = $_POST['start'];}
       
    $result = mysql_query($query) or die("Couldn't execute query");
    $record_count = mysql_num_rows($result);
    
    $max_pages = $record_count / $per_page;
    
        		$start = 0;
    
    
    $query .= "LIMIT $start, $per_page";
    $result = mysql_query($query);
    
    echo "<p>You searched for: <br> "" . $rimp . " " . $dimenzijap . $sezona . " "</p><hr>";
if($result && mysql_num_rows($result) > 0)
{
    $i = 0;
    $max_columns = 4; ?><table class="tabela"><?php
    while($row = mysql_fetch_assoc($result))        
   {    $title = $row["Rim"];  
        $model = $row["model"];
        $dimenzija = $row["Dimenzija"];
        $ime = $row['name'];
        $cena = $row['price']; 
        $cena = number_format($cena, 2, ',', '.');
        $id = $row['product_id'];
                   
   if($i == 0)
          echo "<tr>";
          echo "<td>" ?><a href="index.php?route=product/product&product_id=<?php echo $id?>"><?php echo $model ?></a>
          <?php echo "<br>$dimenzija<br>$ime<br>"; ?>
          <span style="color: #900; font-weight: bold;"><?php echo $cena . "din"?> </span>
          <?php echo "</td>";
           if(++$i == $max_columns) 
       {
           echo "</tr>";
           $i=0;
       } }}
       if($i > 0)
{
   for($j=$i; $j<$max_columns;$j++) echo "<td> </td>";
   echo "</tr>";
}
?>
</table>
<?php 
$prev = $start - $per_page;
$next = $start + $per_page;

?>
<table width="100%" border="1">
<tr><td><?php 
if (!($start<=0)){
echo "<a href='index.php?route=product/search&start=$prev'>Prev </a>";
}
$page = 1;
for($x=0;$x<$record_count;$x=$x+$per_page){
 	echo " <a href='index.php?route=product/search&start=$x'> $page </a> ";
	$page++;
 }

  if (!($start>=$record_count - $per_page)){
echo "<a href='index.php?route=product/search&start=$next'> Next</a>";
}
?></td>
</tr>
</table>

What seems to be the problem?

One quick question. Why when i change method to GET it doesn't do anything (it basically stay on home page)

Your request method is POST. please check page count form your error.

 

Thanks
