help: losing uri segment when failing form validation

[eluser]WanWizard[/eluser]
[quote author="pabloheim" date="1278797691"]in the form, the url in the action attribute the same asthe controller

Code:

<?php echo form_open('controller/edit');?>

as you can see, it doesnt contain the id. im putting it in a hidden input :

Code:

<?=form_hidden('id_item',$id_item)?> //comes from the $data['id_item'] in the controller

then manage all in the model to insert new information[/quote]
So it's quite logical that after you submit the form the id is no part of the URI, since you didn't include it.

You have to retrieve it from the posted form. I recommend not to use $this->input->post(), but to validate it properly using the form validation library, and after validation use set_value() to access the ID variable.
