You may want to to try a different approach using heredoc as it is less prone to quoting errors, here's a complete example to loop a mysqli query using heredoc.
<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="select * from booked where datefrom between '$from' and '$to' or dateto>='$from' and dateto='$to'";
if ($result=mysqli_query($con,$sql))
{
while ($row=mysqli_fetch_row($result))
{
echo <<< LOL
<div class="col-lg-4 col-md-4 col-sm-12">
<div class="newsBox">
<div class="thumbnail">
<figure><img src="reservation/img/rooms/{$row['img']}" width="230" height="150"></figure>
<div class="caption maxheight2">
<div class="box_inner">
<div class="box">
<a class="title"><strong>{$row['name']}</strong></p>
<b>{$row['description']}</b>
<p>{$row['price']}</p>
</div>
<a class="btn btn-default" href="info_pay.php?roomnumber={$row['room_number']}&roomtype={$row['name']}&from={$_POST['from']}&adult={$_POST['adult']}&child={$_POST['child']}&to={$_POST['to']}&roomprice={$row['price']}"><span class="glyphicon glyphicon-plus">Select this Room</span></a>
</div>
</div>
</div>
</div>
</div>
LOL;
// Free result set
mysqli_free_result($result);
}
}
//close mysqli connection
mysqli_close($con);
?>
