Hi,
Please use code tags for readability.
To keep input values in your form do:
In controller:
Code:
# Set all rules - ALSO on the input fields that are not required;
# You _must_ do this to save input data:
$this->form_validation->set_rules('input_field_name', 'Error message', ''); # leave third param empty if input field is not mandatory
# Then do check
if ($this->form_validation->run() == FALSE)
{
# open the form again (load view)
}
else
{
# do something else...
}In your view file:
Code:
$notes = array(
'name' => 'notes',
'value' => set_value('notes'), # This set_value will preserve your input in case form has errors...
'style' => 'width:90%',
);
echo form_textarea($notes);Cheers,
Smilie

Thanks smilie
I did $this->form_validation->set_rules(...); //this validation_errors() could display error message,
but lost current input?
