Why Am I Getting the \'Trying to Get Property of Non-Object\' Error in CodeIgniter?

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

When attempting to update a database record using CodeIgniter, you may encounter the "Trying to get property of non-object" error. This issue arises when attempting to access properties of an object that is not an instance of a class.

In the context of your edit_product_view, you are trying to populate a form using the $product object, which is retrieved based on the product ID selected. However, you are accessing its properties using object notation ($product->prodname).

Resolving the Issue: Object vs. Array Notation

CodeIgniter stores retrieved data as arrays, not objects. Therefore, you should use array notation to access individual elements of the $product array, which contains the values for your form fields.

Replace the following lines:

<code class="php"><?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)); ?></code>

with:

<code class="php"><?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'])); ?></code>

Additional Tips

• Ensure that your $product array contains the correct key-value pairs.
• If you still encounter the error, check that you have properly passed the $product variable to your view.
• Consider using print_r to inspect the contents of your $product array to verify that it contains the expected data.
