Good morning, as I can do to leave the radiobutton selected according to the database, I have a table in the database with the categories being listed in a foreach on the radiobutton, until then beauty, works to insert, but when editing I need a radiobutton to be selected according to the id that is in the products table related to the id field of the table of categories, and in that part I am not able to do, my code below:

<?php
        foreach($listar_categorias as $categoria):
        if($categoria['id'] == $campos['categoria']){ $check = 'checked';}
?>
        <input type="radio" name ="cat_select" value="<?php $categoria['id']; ?>" checked="<?php echo $check; ?>" required="require" /><p><?php echo $categoria['nome']; ?></p>
<?php   
        endforeach;
?>

how the last option of the bank as in the radiobuttons is selected.

php foreach radiobutton

The problem is that the variable $check not being cleaned before checking. That way all items after what should actually be selected will also be with checked="checked". Like property name is equal, the latter with the property checked="checked" will always be marked.

The solution is to clean the variable check:

<?php
    foreach($listar_categorias as $categoria):
        $check = '';
        if($categoria['id'] == $campos['categoria']){
            $check = 'checked="checked"';
        }
?>
    <input type="radio" name ="cat_select" value="<?php $categoria['id']; ?>" <?php echo $check; ?> required="require" /><p><?php echo $categoria['nome']; ?></p>
<?php   
    endforeach;
?>

Notice that I switched the contents of the variable $check of checked for checked="checked", because if the item should not be marked, nor need to declare the property checked.
