Question

I am adding a checkbox to my form using:

$fieldset->addField($value, 'checkbox', array(
                    'label'     => $label,
                    'name'      => $value,
                    'checked' => false,
                    'onclick' => "",
                    'onchange' => "",
                    'value'  => $value,
                    'disabled' => false,
                    'tabindex' => 1
                ));

Then in my controller I am doing:

if (isset($this->post[$value]))
                {
                    $webCategory = $this->post[$value];
                    if ($webCategory != '') {
                        Mage::log("Syncing: " . $webCategory);
                    }
                }

$this->post is the Mage::app()->getRequest()->getPost() from the page. $value contains the id of the checkbox (all the data is dynamic so I have posted snippets).

The issue I have is that the checkbox values are always getting logged even when I don’t tick them. I always thought checkboxes weren’t posted unless they were ticked. Am I losing it or does Magento do something odd?

Answer 1

First check your browser: What data get POSTed? The network tab of your browser’s debugger (e.g. Firebug for Firefox) will tell you. Are the checkboxes data in there?

Second, check the HTML: Are the checkbox names defined multiple times? That might be the reason for them to show up in your POST data.
