Magento – Change product price on selection of custom option (checkbox)

custom-optionsmagento-1.9priceproduct-list

I have displayed Magento products on my site's homepage. Some products have some custom options of checkbox type. I have displayed those custom options under the product image. But I do not have any idea how to change particular product price after checking or unchecking that custom option checkbox.

Here is the code which I have used to display custom options:

$options = Mage::getModel('catalog/product_option')->getProductOptionCollection($emq_product);

//for showing custom options
foreach($options as $o) {
    //echo $o->getTitle();
    $emq_type = $o->getType();
    if ($emq_type=="checkbox") {
        foreach($o->getValues() as $v) {
            echo $v->getTitle();
            echo "<input  id='".$emq_prod_id."' type='checkbox' class='emq_chk' price='". number_format($v->getPrice())."'/>";
        }                           
    }
}

You need to give a price to the option, get a look at the screenshot

I don't know if recommending an extension counts as a valid answer (for a question with a bounty) but someone claims here that he wrote an extension that does exactly what you need. Extension can be downloaded from here. I haven't tested it but, as soon as I do, I will post and update. I only looked through the code and there is a lot of it. I lost interest after 2 files. I hope it works for you.

[EDIT]
I've got my interest back. I tested the extension on ce-1.7.0.2 and it (almost) works.
If you use it with developer mode on you will get some errors. Here is what you need to change to make it work.
in /app/code/local/Magebuzz/Customoption/controllers/Adminhtml/CustomoptionController.php on line 28 there is this:

$model->setData('value['.$option_id.']',$value[0]['option_type_id']);

This shows an 'undefined index' warning. To avoid it, wrap it in an if statement.

if (isset($value[0])){
    $model->setData('value['.$option_id.']',$value[0]['option_type_id']);
}

In /app/code/local/Magebuzz/Customoption/Block/Adminhtml/Customoption/Edit/Tab/Form.php on line 129 there is this:

foreach ($values as $value) {
    $valuesArr[$value['option_type_id']]=$value['title'];
}

$values may be null so change the code to this:

if (is_array($values)){
    foreach ($values as $value) {
        $valuesArr[$value['option_type_id']]=$value['title'];
    }
}

Now it should work.
Now some review.

PRO. Works perfectly for dropdown and radio custom options
Neurtal. Kind of works for multiple select and checkbox custom options. You can select only one value for the available values.
Inconvenient but I can overlook it. in order to set the default values you have to click on an other menu item in the backend and look for your product in the list.
Con. It doesn't work for text, textarea, date, datetime, time, file custom options. But with a little work it can be changed to work correctly for all types (maybe except file).

Magento – Custom Options Price Value

You need absolute pricing - if you search the Magentocommerce forums you will find it. We use an embedded extension which includes it but it is part of a complete pricing solution so wouldn't work for you.
