匹配数组值与嵌套while循环内的输入字段

Question

It's a really silly problem.i don't know how i get this but i get. i have a array and i wants to match array values with checkbox which came from while loop.So how is it possible.

                  //Array that i want to match with checkbox
                  $filter = explode(',', $getproduct->specification_filter);
                  <table class="table" style="background-color: white;">
                      <tbody>
                        <?php
                          while($fch = $allfilter->fetch_array()){
                        ?>
                        <tr>
                          <th><?=$fch[2]?></th>
                          <?php 
                          $sqlbv="SELECT * FROM product_filter where idd='$fch[4]'";
                          $resultbv=$conn->query($sqlbv);
                          while($rowbv = $resultbv->fetch_array()){
                        ?>
                          <td>
                            <label class="ckbox ckbox-danger">
                                <input type="checkbox" value="<?=$rowbv[0]?>" name="pfilter[]">
                                <span>&nbsp;&nbsp;<?=$rowbv[3]?></span>
                              </label>
                          </td>
                          <?php } ?>
                        </tr>
                        <?php } ?>
                      </tbody>
                    </table>

Now i wants to check Checkbox field if $filterarrays value match with checkbox value. So how can i do that ?

Answer 1

since your $filter is an array use in_array

 <input type="checkbox" value="<?=$rowbv[0]?>" <?=  in_array($rowbv[0], $filter)? 'checked':''  ?> name="pfilter[]">

for more details see in_array.
