How to populate check boxes from Mysql database? - php

Question

I want to retrieve data to check-box list when user selected an option from a drop-down list. So, the main categories are loaded in a drop-down list and subcategories are suppose to be loaded in a list of check-boxes. Right now, I sorted out to populate data to another drop-down list. here is my code:
JQuery Code:
<script type="text/javascript">
$(document).ready(function() {
$("#parent_cat").change(function() {
$(this).after('<div id="loader" style="position:inline;"><img src="device manager/img/loading.gif" alt="loading subcategory" /></div>');
$.get('user manager/loadsubcat.php?parent_cat=' + $(this).val(), function(data) {
$("#sub_cat").html(data);
$('#loader').slideUp(200, function() {
$(this).remove();
});
});
});
});
</script>
PHP Code:
<tr>
<?php
include('config.php');
$query_parent = mysql_query("SELECT * FROM tblclient") or die("Query failed: ".mysql_error());
?>
<form method="get">
<tr>
<td><label>Client</label></td>
<td>
<select name="parent_cat" id="parent_cat">
<option selected="selected" disabled="disabled">Select a Client</option>
<?php while($row = mysql_fetch_array($query_parent)): ?>
<option value="<?php echo $row['clientId']; ?>"><?php echo $row['clientName']; ?></option>
<?php endwhile; ?>
</select>
</td>
</tr>
<br/><br/>
<tr>
<td><label>Branch</label></td>
<td>
<select name="sub_cat" id="sub_cat" multiple>
<option selected="selected" disabled="disabled">Select a Branch</option>
</select>
</td>
</tr>
</form>
Loading subcategory list PHP Code:
<?php
include('config.php');
$parent_cat = $_GET['parent_cat'];
$query = mysql_query("SELECT B.*, C.* FROM tblbranch B INNER JOIN tblclientbranch CB on CB.branchId = B.branchId INNER JOIN tblclient C ON CB.clientId = C.clientId WHERE C.clientId = {$parent_cat}");
while($row = mysql_fetch_array($query)) {
echo "<option value='$row[branchId]'>$row[branchName]</option>";
}
?>
Does anyone know how to populate subcategories to a list of check-boxes?
Any solution would be great.
Thanks for reading my long code!

Answer 1

something like
<input type="checkbox" name="branch" value="$row[branchid]">$row[branchname]<br>
