How to get checkboxes remained checked after being checked in another device - php

Question

I am facing some issues trying to get checkboxes to stay checked in another device, I am able to get check boxes stay checked within the browser, so after the browser refreshed, the checkboxes remained checked, so is there any idea how i can do this?
so here is my code, firstly i included the dcConnect.php to connect to the database then i retrieve the data from the database to be displayed on a website
<?php
include_once("dcConnect.php");
$dcData = "SELECT dcID, dcServerName, dcServerAge, dcServerGender, dcServerMarital FROM dcUsers";
$result = $link->query($dcData);
if($result->num_rows >0){
echo"<table><tr><th></th><th>ID</th><th>Name</th><th>Age Group</th><th>Gender</th><th>Marital Status</th></tr>";
while($row = $result->fetch_assoc()){
echo"<tr><td><input type='checkbox' id='". $row["dcID"] ."' name='". $row["dcID"] ."' value='off' ></input></td><td>". $row["dcID"] ."</td><td>". $row["dcServerName"] ."</td><td>". $row["dcServerAge"] ."</td><td>". $row["dcServerGender"] ."</td><td>". $row["dcServerMarital"] ."</td></tr>";
}
echo "</table>";
}else{
echo"no results";
}
$link->close();
?>
Here is my website where the check boxes can stay checked after refreshed but not in another device

Answer 1

It looks like currently you are using cookies to save the state of the checkboxes. Cookies are stored on the clientside (i.e. the user's computer) and not the server side, which is why you are not seeing the checkbox state preserved across devices.
In order to save and retrieve the checkbox state in the database, you will need to add an additional column to your database table. Following your pattern above, this would probably be a boolean column named something lke 'dcChecked'.
Then when you are printing your inputs, you would want to do something like this:
<input type="checkbox" <?php if($row['dcChecked']) { print 'checked' } ?></input>
(This is simplified for clarity, you'll still want to include your other attributes for ID, name, etc)

<?php
include_once("dcConnect.php");
$dcData = "SELECT dcID, dcServerName, dcServerAge, dcServerGender, dcServerMarital, dcChecked FROM dcUsers";
$result = $link->query($dcData);
?>
<?php if($result->num_rows > 0): ?>
<table>
<tr>
<th></th><th>ID</th>
<th>Name</th>
<th>Age Group</th>
<th>Gender</th>
<th>Marital Status</th>
</tr>
<?php foreach($rows as $row): ?>
<tr>
<td><input type='checkbox' id="<?php print $row["dcID"]; ?> " name="<?php print $row["dcID"]?>" value='off' <?php if($row["dcChecked"]): ?>checked<?php endif;?>></input></td>
<td><?php print $row["dcID"]; ?></td>
<td><?php print $row["dcServerName"]; ?></td>
<td><?php print $row["dcServerAge"]; ?></td>
<td><?php print $row["dcServerGender"]; ?></td>
<td><?php print $row["dcServerMarital"]; ?></td>
</tr>
<?php endforeach; ?>
</table>
<?php else: ?>
No results
<?php endif; ?>
Here's what the syntax would look like in context. I also refactored this a bit to make it a bit more readable.
