CodeIgniter表单验证Greater_than_equal_to无法正常工作

Question

I have this code

$this->form_validation->set_rules('MinimumSalary', 'Minimum Salary', 'trim|required|min_length[1]|max_length[20]|numeric|greater_than_equal_to[0]');
$this->form_validation->set_rules('MaximumSalary', 'Maximum Salary', 'trim|required|min_length[1]|max_length[20]|numeric|greater_than_equal_to[MinimumSalary]');

and yet it always throws up an error when I enter MinimumSalary = 100 and MaximumSalary = 200, The Maximum Salary field must contain a number greater than or equal to Minimum Salary

Answer 1

尝试这个

'trim|required|min_length[1]|max_length[20]|numeric|greater_than_equal_to['.$this->input->post('MinimumSalary').']');
