You can check whether the request method is 'post'. If so, take the posted data into an array. Then scan the array for keys that begin with 'mechanic_'. For the detected such keys make the corresponding validation rules and register them. After that you can call if $this->form_validation->run() { ... } else { ... }

No, you should do this.

so i could be wrong but i think it could be something like this - say if you are doing it in a form validation array,
and somehow you get the id in there - which keep in mind could be in a hidden form field
PHP Code:
array(
$fieldname = 'mechanic_' . $theid ;
'field' => $fieldname,
'label' => 'Mechanic',
'rules' => 'trim|required|max_length[100]'
),
also keep in mind that you can do form validation in separate methods - so for example you could check that the ID is valid before validating the mechanic field, etc

Use foreach to check the indexes of all post data.
Controller:
PHP Code:
function validate()
{
$rules = array();
foreach($this->input->post() as $name => $value)
{
if(strpos($name, 'mechanic_') !== false)
{
$rules[] = array(
'field' => $name,
'label' => [some label],
'rules' => [some rules]
);
}
}
// set_rules can accept multi-dimensional array
$this->form_validation->set_rules($rules);
}
Views:
<?php echo form_error('mechanic_134') ?>
<select name="mechanic_134" id="mechanic-134" class="form-control selectpicker">
