i found that data without validate rules wont repopulate
is that right?
if so how can to prevent this, add rules for every field?
that's what confused me

That is correct. The form validation library only loads variables that are mentioned in the rules definition.
So you'll have to add a rule (even a simple one, like 'trim' to remove whitespace) to each field.

another question
how to validate the field array
just like as
<input type="text" name="field" /
<input type="text" name="field" /
<input type="text" name="field" /

I don't think that works as an array. Only one field will be returned. If you want an array, you need to name the fields "field[]". Now, if you need to validate the array, you'll just need to write your own validation callback function on "field" which will pass in the array.
Good luck with your project.

Hello, this is my first post here. I'm dealing with the same problem (repopulating form fields), but it doesn't work with some fields even if I set validation rules. Here is a chunk of my controller and view code.
Controller action "signup":
Code:
$this->form_validation->set_rules('username', 'User name',
'trim|required|min_length[3]|max_length[20]|alpha_dash|xss_clean');
$this->form_validation->set_rules('email', 'Email',
'trim|required|valid_email');
$this->form_validation->set_rules('password', 'Password',
'trim|required|min_length[6]|max_length[20]|md5');
$this->form_validation->set_rules('password2', 'Repeat password',
'trim|required|matches[password]');
$this->form_validation->set_rules('first_name', 'Name',
'trim|max_length[50]|alpha|htmlentities|xss_clean');
$this->form_validation->set_rules('last_name', 'Surname',
'trim|max_length[50]|alpha|htmlentities|xss_clean');I've set up validation rules for all the form fields.
View: signup_view
Code:
<?php echo form_open('user/signup'); ?>
<div class="form_required_field_label">User name</div>
<?php echo form_error('username'); ?>
<input type="text" name="username" value="<?php echo set_value('username'); ?>" size="30" />
<div class="form_required_field_label">Email</div>
<?php echo form_error('email'); ?>
<input type="text" name="email" value="<?php echo set_value('email'); ?>" size="60" />
<div class="form_required_field_label">Password</div>
<?php echo form_error('password'); ?>
<input type="password" name="password" size="30" />
<div class="form_required_field_label">Repeat password</div>
<?php echo form_error('password2'); ?>
<input type="password" name="password2" size="30" />
<div class="form_required_field_label">Name</div>
<?php echo form_error('first_name'); ?>
<input type="text" name="first_name" value="<?php set_value('first_name'); ?>" size="60" />
<div class="form_optional_field_label">Surname</div>
<?php echo form_error('last_name'); ?>
<input type="text" name="last_name" value="<?php set_value('last_name'); ?>" size="60" />
<div><input type="submit" value="Send" /></div>
</form>I want fields username, email, first_name and last_name to be repopulated, but if I insert non valid data, only the username and email fields are repopulated; first_name and last_name do not. Did I make some obscene error?
Thank you very much,
Gica

here it is, compare these two lines
Code:
value="<?php echo set_value('username'); ?>Code:
value="<?php set_value('first_name'); ?>"second one is missing the word 'echo', if you add that it should work

Thank you! I apologize, perhaps I was sleeping when I wrote and reread those few lines.
Thank you again,
