## Why am I Getting the \"Trying to Get Property of Non-Object\" Error in CodeIgniter?

Troubleshooting "Trying to Get Property of Non-Object" Error in CodeIgniter

In CodeIgniter, when attempting to update a form with retrieved data for a specific ID, it's possible to encounter the error "Trying to get property of non-object." This issue generally arises due to incorrect usage of object or array notation when accessing retrieved data.

To resolve this error, it's crucial to use the array notation, $product['property'], when accessing array elements. In your provided code excerpt, you're attempting to access array elements using object notation, $product->property, which is applicable for object attributes and methods only.

Here's a corrected version of your edit_product_view:

<?php echo form_input('prodname', set_value('prodname', $product['prodname'])); ?>

<?php echo form_dropdown('ptname_fk', $product_types, set_value('ptname_fk', $product['ptname_fk'])); ?>

By utilizing array notation, your form will correctly populate with the retrieved data for the selected product.
