根据选中的复选框存储数组元素？

Question

I've got this problem that I can't solve. Partly because I can't explain it with the right terms. I'm new to this so sorry for this clumsy question.

Below you can see an overview of my goal. I am displaying my check boxes in a for loop.

Here I am getting the all values in an array, but I want store the array elements based on the check box checked.

<?php 
    $j=0;
    $arr = Array();
foreach($collection as $data) {  
    $mageid=$data['mageproductid'];
    $products = Mage::getModel('catalog/product')->load($mageid);
    $productMediaConfig = Mage::getModel('catalog/product_media_config');       
    $checkeven=0;
        $arr[$j]=$products->getId();
        //echo $arr[$j];
    $j++;
} ?>

My checkbox code:

 <form id="check_all" action="" method="POST" name="check" >
<input type="checkbox" class="multid[]" id="<?php echo $products->getId();?>"  value="checked" />  </form>

What do I have to do in order to get checked values in my array? Did I do anything wrong?

Answer 1

After submiting the form you can get an array of checked products with $_POST['multid']
