PHP Database search display - php

Question

To give you an understanding of what I'm working on. I'm working on a project where on my school campus you can navigate around. For example a room can be called J2626 or J2617 etc... The thing is that when a user Is using my website I only want it to type in the exact name of the room to be able to display anything. Right now it doesn't work like I want it to.
For example: if you only type in J in the search field, it will display all rooms that start with J.
Here is my code right now:
<?php
$fileName = dirname(dirname(__FILE__)) . "../../db/bth_nav.sqlite";
if (isset($_GET['page'])) {
$argument = $_GET['page'];
$argument = "%" . $argument . "%";
$db = new PDO("sqlite:$fileName");
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
$stmt = $db->prepare('SELECT * FROM bth_nav WHERE name LIKE (:nameOwner) OR owner LIKE (:nameOwner);');
$stmt->execute(array($argument));
$res = $stmt->fetchAll(PDO::FETCH_ASSOC);
if (empty($res)) {
header("Location: " . "http://" . $_SERVER['index.php']);
}
?>
<div class = "formObjectSearch">
<?php foreach ($res as $val) { ?>
<div class = "infoTab">
<h2><?= $val['name']; ?></h2>
<p>Guidance: <?= $val['info']; ?></p>
<p>Whos sitting here?: <?= $val['owner']; ?>
</div>
<img class = "buildingImage" src = "img/<?= $val['image']; ?>"
<?php
}
}
?>
</div>
I've tried making diffrent if statements but with no success. So what I need help with is that I only want the user to be able to search for a correct room name and not be able to only search for J and display everything.
Update
Here is my index.php:
I used this link, because Code sample didn't want to work: index.php code
Here is my building.php:
Samer here: building.php code
And the the new search.php with help:
Same here: search.php code
I get these errors right now:
Notice: Undefined index: index.php in /path/incl/files/search.php on line 19
Warning: Cannot modify header information - headers already sent by (output started at /path/incl/header.php:7) in /path/incl/files/search.php on line 19
My header.php code:
Same here: header.php code
My config.php code:
Same here: config.php code
My footer.php code:

If i understanded you correctly and if you want to search for all rooms with starting letter J, you need to change your arguments.
Explanation:
'%J%' - searches for selected field, where is J letter.
'%J' - searches for selected field, where J is the last letter.
'J%' - searches for selected field, where J is the first letter.
Try to change your argument like that:
$argument = $argument . "%";
UPDATE
Fixing your if statement:
if (empty($res) OR $res == null) {
header('Location: http://'.$_SERVER['index.php']);
}
else {
echo '<div class = "formObjectSearch">';
foreach ($res as $val) {
echo '<div class = "infoTab">';
echo '<h2>'.$val["name"].'</h2>';
echo '<p>Guidance:'.$val["info"].'</p>';
echo '<p>Whos sitting here?:'.$val["owner"].'</p>';
echo '</div>';
echo '<img class="buildingImage" src="img/'.$val['image'].'" />';
}
echo '</div>';
}
OR
You can try to replace empty, with:
if ($res->rowCount() > 0) {
// if founded
} else {
// header('Location: http://'.$_SERVER['index.php']);
}
