Dropdown Menu Selection to Populate Form - php

Question

Hi all,
I am trying to populate a form from MySQL using a dropdown menu to select the row I want displayed.
The dropdown is displaying the items I need. But what I want to do is select one of the items in the dropdown, which will fill in the form with the items I need for editing.
Here is the code I have so far, including the form. Any help you guys can give would be really appreciated.
The Select:
<div class="panel panel-primary">
<div class="panel-heading"> Manage Tours</div>
<div class="panel-body">
<form role="form" method="post" action="">
<label for="singleSelect">Choose Tour to Edit</label>
<select class="form-control" name="tour_select">
<?php
$result = mysqli_query($mysqli,"SELECT tour_name FROM tours order by id");
while($row = mysqli_fetch_array($result))
echo "<option value='" . $row['tour_name'] . "'>" . $row['tour_name'] . "</option>";
?>
</select>
This works fine.
The form, which also works fine with a simple select query:
<div class="form-group">
<label>Tour Name</label>
<input class="form-control" name="tour_name" value="<?php echo $row['tour_name']; ?>" />
</div>
<div class="form-group">
<label>Destination</label>
<textarea class="form-control" name="tour_to" rows="4"><?php echo $row['tour_to']; ?></textarea>
</div>
<div class="form-group">
<label>Collection</label>
<textarea class="form-control" name="tour_from" rows="4"><?php echo $row['tour_from']; ?></textarea>
</div>
<div class="form-group">
<label>Date</label>
<input class="form-control" name="tour_date" value="<?php echo $row['tour_date']; ?>" />
</div>
<div class="form-group">
<label>Pickup Time</label>
<input class="form-control" name="tour_time" value="<?php echo $row['tour_time']; ?>" />
</div>
<div class="form-group">
<label>Itinerary</label>
<textarea class="tinymce" id="tinymce" name="tour_details" rows="12" ><?php echo $row['tour_details']; ?></textarea>
</div>
<button type="submit" name="Submit" class="btn btn-primary">Save Changes</button>
</form>
But, when I select an option from the dropdown, I need the form to be populated with the data from that database table row. I hope I am making sense.
I have searched for days on Google but found nothing.
I have changed the form from a dropdown to an html table with a Delete button.
Here is the code with table:
<?php
if (isset($_GET['id'])) {
if (isset($_POST['Delete'])) {
$remove = $mysqli->prepare("DELETE FROM `tours` WHERE `id` = $id");
$id = $_POST['id'];
$remove->bind_param('ssssss', $id);
if(!$remove->execute() === true) {
echo $mysqli->error;
}
}
}
$sql = "SELECT * FROM tours";
$result = $mysqli->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
?>
<tbody>
<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['tour_name']; ?></td>
<td><?php echo $row['tour_to']; ?></td>
<td><?php echo $row['tour_from']; ?></td>
<td><?php echo $row['tour_date']; ?></td>
<td><?php echo $row['tour_time']; ?></td>
<td><input type="submit" name="Delete" value="Delete" onclick="" /></td>
</tr>
</tbody>
<?php
}
?>
</table>
</form>
I appreciate any help.

Answer 1

Say you want to preselect a particular tour with $tour_id = 5. You can then modify your code to:
echo "<option value='" . $row['tour_name'] . "'" . ($row['id'] == $tour_id ? " selected" : "") . ">" . $row['tour_name'] . "</option>";

Answer 2

I have found the solution should anyone need it in future.
<?php
if (isset($_POST['Delete'])){
$checkbox = $_POST['checkbox'];
$count = count($checkbox);
for($i=0;$i<$count;$i++){
if(!empty($checkbox[$i])){ /* CHECK IF CHECKBOX IS CLICKED OR NOT */
$id = mysqli_real_escape_string($mysqli,$checkbox[$i]); /* ESCAPE STRINGS */
mysqli_query($mysqli,"DELETE FROM tours WHERE id = '$id'"); /* EXECUTE QUERY AND USE ' ' (apostrophe) IN YOUR VARIABLE */
} /* END OF IF NOT EMPTY CHECKBOX */
} /* END OF FOR LOOP */
} /* END OF ISSET DELETE */
$sql = "SELECT * FROM tours";
$result = $mysqli->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$id = mysqli_real_escape_string($mysqli, $row['id']);
?>
<tbody>
<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['tour_name']; ?></td>
<td><?php echo $row['tour_to']; ?></td>
<td><?php echo $row['tour_from']; ?></td>
<td><?php echo $row['tour_date']; ?></td>
<td><?php echo $row['tour_time']; ?></td>
<?php echo "<td><input type='checkbox' name='checkbox[]' value='$id'></td>"; ?>
</tr>
</tbody>
<?php
}
?>
Thanks all for the help. Really appreciate it.
