php - Display each color separate with values -


i having trouble in printing values database.

item table

item | color | material | dimensions | category | quantity - 01    33      05           111         12         1000.00 - 02    33      07           125         18         200.00 - 03    33      11           156         18         254.00 - 04    56      15           25          66         113.00 - 05    66      05           11          33         521.00

i trying print values in table(for each color print material dimension category) output be:

color - > 33 material | dimension | category  | quantity 05          111          12          1000.00 07          125          18          200.00 11          156          18          254.00  color - > 56 material | dimension | category  | quantity 15          25           66          113.00  color - > 66 material | dimension | category  | quantity 05          11           33          521.00

i using query

$query = "select a.itemnb, b.colorname, c.materialname, d.categoryname, sum(a.quantity) quantity  dbo_items join dbo_color b on a.color=b.colorid join dbo_material c on a.material=c.material join dbo_category on a.category=d.categoryid group b.colorname, c.materialname, d.categoryname, ";

i using pdo. 

$q=$conn->query($query);

now can fetch values in table, not want make. 

<table class="table table-bordered table-striped">   <thead>     <tr class="bg-primary">       <td data-field="color">color</td>       <td data-field="material">material</td>       <td data-field="dim">dimensions</td>       <td data-field="quantity">quantity</td>     </tr>   </thead>   <tbody>     <?php while ($r = $m->fetch()){?>      <tr>       <td><?=$r['colorname']?></td>       <td><?=$r['materialname']?></td>       <td><?=$r['categoryname']?></td>       <td><?=$r['quantity ']?></td>    <?php } ?>   </tbody> </table>

i want print first color , material related color. having trouble there, or advice appreciated?

first remove colorname field group by clause in query , add column order by means add order colorname in query.

and change html , php code following:

<table class="table table-bordered table-striped">   <thead>     <tr class="bg-primary">       <td data-field="color">color</td>       <td data-field="material">material</td>       <td data-field="dim">dimensions</td>       <td data-field="quantity">quantity</td>     </tr>   </thead>   <tbody>     <?php    $tempcolor = '';   while ($r = $m->fetch()){   if($tempcolor != $r['colorname']) {    ?>    <tr><td colspan="4">color name: <?=$r['colorname']?></td></tr>   <?php $tempcolor = $r['colorname'];   } else {    ?>      <tr>       <td><?=$r['colorname']?></td>       <td><?=$r['materialname']?></td>       <td><?=$r['categoryname']?></td>       <td><?=$r['quantity ']?></td>    <?php }    }     ?>   </tbody> </table>
