<li class="treeview">     <a href="#"><i class="fa fa-tachometer"></i> <span>dashboard</span></a>     <ul class="treeview-menu">         <li style="padding-left: 5px;">             <a href="#"><i class="active fa fa-search"></i> <span>searches</span> <i class="fa fa-angle-left pull-right"></i></a>             <ul class="treeview-menu">                 <div id="checkbox-container">                     <li style="padding-left: 10px;">                         <input type="checkbox" id="selectall" onclick='selectall(this.checked)'/>                         <span style="color: #fff;">select all</span>                     </li>                     <?php foreach ($query $search_row) { ?>                         <?php foreach($checksearch $s) { ?>                             <?php                                  $box = 0;                                 if($search_row->searchid == $s->idsearch){                                     $box = 1;                                 }                             ?>                             <form method="post" id="the-dash">                                 <li style="padding-left: 10px;">                                     <input type="checkbox" id="searches" class="searchid" onclick="getsearchid()" value="<?php echo $search_row->searchid; ?>" name="searchname"  <?php echo ($box == 1 ? 'checked' : ''); ?>>                                      <span id="searchname" style="color: #fff; "><?php echo $search_row->searchname; ?> <?php echo '<br>'; ?><span>                                 </li>                             </form>                         <?php } ?>                     <?php } ?>                 </div>             </ul>         </li>     </ul> </li> 

try this

in controller, store id in array

$idsearchs = array(); foreach($checksearch $s) {     $idsearchs[] = $s->idsearch; } 

in view

<?php foreach ($query $search_row) {     $box = in_array($search_row->searchid, $idsearchs) ? 1 : 0; ?>     <li style="padding-left: 10px;">         <form method="post" id="the-dash">             <input type="checkbox" id="searches" class="searchid" onclick="getsearchid()" value="<?php echo $search_row->searchid; ?>" name="searchname"  <?php echo ($box == 1) ? 'checked="checked"' : ''; ?>>              <span id="searchname" style="color: #fff; "><?php echo $search_row->searchname; ?> <?php echo '<br>'; ?><span>         </form>     </li> <?php } ?> 

you have done foreach $query , in side foreach $checksearch, there getting duplicate checkbox.
