Retaining checked status of checkboxes in a form

[FeralReason]

(HTML Form, using PHP) I have a form that, in the event of a user error, I want displayed again with the values just entered. I have solved this for the text boxes but, no matter what I try I have not been able retain the checked status of the checkboxes. Does anyone know how to do this ?

This should belong in the PHP forum, but here's my idea.

 

You create an associative array of values for those checkboxes.

 

Say you have this:

<input type="checkbox" name="foods[]" value="rice" /> Rice
<input type="checkbox" name="foods[]" value="ramen" /> Ramen
<input type="checkbox" name="foods[]" value="chicken" /> Chicken
<input type="checkbox" name="foods[]" value="pizza" /> Pizza

 

Then have this array (assuming you submitted the form in post method)

$food_values = array();
$foods = $_POST['foods'];
foreach ($foods as $value) {
     $food_values[] = $value;
}

 

That would set $food_values to have all the values of the checkboxes that are checked. I guess you can have another array that contains a list of all checkboxes. If you have them in the DB, query the DB, but you get the point right?

To set a checkbox as checked use the attribute checked="checked" on the input.

<input type="checkbox" checked="checked" />
