将Codeigniter 1.7.1升级到3.6

Question

I need upgrade my website codeigniter to V 3.6 from V 1.7.1 , but I don't know where I can find the version 1.7.2 because that isn't in the repository.

I use this user guide ( http://www.codeigniter.com/user_guide/installation/upgrading.html ) for upgrade but this is absolutely necessary to do all the steps 1.7.1 to 1.7.2, 1.7.2 to 2.0,... or can I do directly from version 1.7.1 to the last version 3.6 ?

Thanks!

Indeed, as cartalot said, you don't need to upgrade through each version, one by one. Just read all the instructions to upgrade between your version and the target one, and build a list of things to do, then you can execute that list on one go. Here are some of the things that I added to my list when upgrading from 1.7.2 to 3.1.3.

• Add return parent::__get($prop); to your _get magic methods (if you have them).

• Replace $this->validation->error_string with validation_errors()

• Replace in views $this->validation->field_name with set_value('field_name') and set_select() , etc.. And add the value to be used to pre-populate each field. But take in account that set_value() does not work if you don't run form_validation->run() first.

• When retrieving data: Replace $this->validation->field_name and $this->form_validation->field_name with $this->input->post('field_name')

• When setting data: Replace $this->form_validation->field_name with $this->form_validation->set_data($data);

• Take in account that set_data($other_data) overwrites the content of $_POST , so you need to merge $other_data and $_POST .

Good luck, and just power through it!.
