尝试从数据库中取回复选框状态并将其显示在表单上

I am in the process of creating a simple web application to track visitors to a church. I have created the form that is used to add visitors to the database and am using several check boxes for yes/no answers as per below which works perfectly and enters either yes or no to the db depending on the status of the checkbox.

<input type="hidden" value="no" name="relationship">
<input type="checkbox" value ="yes" name="relationship">

Now, here is where I'm having an issue. I have been asked to add in the ability for the administrator to be able to update the records using a similar form layout. I have managed to get the text boxes to pull the existing from the database by using code like below.

First Name: <input type="text" name="first_name" id="first_name" value="<?php echo $visitor_data['first_name'], ' '; ?>">

However, how can I do the same for a checkbox? I have searched here and can not find anything about it. Greatly appreciate your time.

    You just have to check the value and set your checkbox to checked:

    <input type="checkbox" value="yes" name="relationship" <?php if ($visitor_data['checkbox'] == "yes"){ echo 'checked="checked"'} ?>/>
