php - Passing selected date value to a query -


this question has answer here:

i found similar questions here of solutions don't work me. have form 'jquery ui date picker' , want search results on given date. tried changing date formats doesn't return result.

search form-

<div class="form-group row">     <label for="duration" class="col-sm-4 col-form-label">     <input type="checkbox" name="search2" value="checkbox" id="duration" class="search2"> duration</label>     <div class="col-sm-4">     <input type="date" class="form-control input-sm data2" name="data1" id="startdate" placeholder="start date" disabled="disabled">     </div>     <div class="col-sm-4">     <input type="date" class="form-control input-sm data2" name="data2" id="enddate" placeholder="end date" disabled="disabled">     </div>     </div>

search query-

    $sql = "select * reservation      inner join package on reservation.tid = package.tid      inner join reservation_type on reservation.type = reservation_type.id     inner join customer on reservation.cid = customer.cid        inner join reservation_status on reservation.status = reservation_status.id          " ;     if(isset($_post['search2'])){ $start_date = date('y-m-d', strtotime($_post['data1'])); $sql .= " start_date = $start_date and" ; }     if(isset($_post['search2'])){ $end_date = date('y-m-d', strtotime($_post['data2'])); $sql .= " end_date = $end_date and" ; }     if(isset($_post['search'])){ $rid = mysqli_real_escape_string($db, $_post['data']); $sql .= " rid = $rid and" ; }        if(isset($_post['search3'])){ $cid = mysqli_real_escape_string($db, $_post['data3']); $sql .= " reservation.cid = $cid and" ; }     if(isset($_post['search5'])){ $tid = mysqli_real_escape_string($db, $_post['data5']); $sql .= " reservation.tid = $tid and" ; }     if(isset($_post['search6'])){ $type = mysqli_real_escape_string($db, $_post['data6']); $sql .= " reservation.type = $type and" ; }     if(isset($_post['search4'])){ $status = mysqli_real_escape_string($db, $_post['data4']); $sql .= " status = $status and" ; }          $sql = rtrim($sql, "and") ;       $result = mysqli_query($db, $sql)or die("error: ".mysqli_error($db));      $num_rows = mysqli_num_rows($result);      if($num_rows >0){      while ($row = mysqli_fetch_assoc($result)) {     ?> <tr align="center"> <td><?php echo $row["start_date"]; ?></td> <td><?php echo $row["end_date"]; ?></td>

checkbox selection-

$(".search2").on('click', function() { if($(this).is(':checked')){     $(".data2").prop('disabled',false); } else {     $(".data2").prop('disabled',true); } })

jqueryui-

$( function() {                             var dateformat = "yy-mm-dd",                               startdate = $( "#startdate" )                                 .datepicker({defaultdate: "+1w",changemonth: true, numberofmonths: 1})                                 .on( "change", function() {enddate.datepicker( "option", "mindate", getdate( ) );}),                               enddate = $( "#enddate" )                                 .datepicker({defaultdate: "+1w",changemonth: true,numberofmonths: 1})                                 .on( "change", function() {startdate.datepicker( "option", "maxdate", getdate( ) );});                              function getdate( element ) {                               var date;                               try {                                 date = $.datepicker.parsedate( dateformat, element.value );                               } catch( error ) {                                 date = null;                               }                               return date;                             }                           } );                  $('#startdate').datepicker({dateformat: 'yy-mm-dd'});                 $('#enddate').datepicker({dateformat: 'yy-mm-dd'});

query works fine other ckeckings (as image below); search result 1

but not date, search result 2

i student , new coding. appreciated! thank you.

in query, put single quotes values : eg :

$sql .= " start_date = '$start_date' and" ;
