Question

I have a misunderstanding regarding some dynamic row inserts in a MySQL table.

All I want to do is based on the EAV Model:

• I have a products table which contains products
• A attributes table which contains attributes (name) for products (group based – related to category)
• And a product_attribute which contains the value of the attribute

And the user must create this attributes to be associated with a product, and I’m thinking to insert <input> elements with jQuery’s append.

But how to track inserts and how to append them to have a specific name : <input name=''>.

The result should do the following:

<form action='attribute_insert.php' method='post'>
<input name='field1' />
<input name='field2' />
<input name='field3' />
....
<input name='field20' />
</form>

and after processing in attribute_insert.php to insert like this :

('1', '12', 'manufacturer');
('2', '12', 'freq');
('3', '12', 'memory');
('4', '12', 'ram');
....
('20', '12', 'blablabla');

How can I do this … using foreach to scan the $_POST[] or there is a clever method?

Answer 1

Why not name them field[], then you don’t have to worry about the number. In PHP you can just do a for loop over $_POST['field'], since it will return an array of the fields 😉
