CodeIgniter select_value in form_dropdown

I have a drop down box in my form, and when I click the submit button, the form passes the check, and if an error occurs, return the entire value. This work will be expected for my dropdown meu, I have a set_value value in the drop-down list, but it does not work :(

Here is my code

<?php echo form_dropdown('gender', $gender, set_value('gender')); ?>

What am I doing wrong or missing?

This worked well:

<?php
$selected = ($this->input->post('gender')) ? $this->input->post('gender') : 'M';  
$gender = array("M" => "Male", "F" => "Female");
echo form_dropdown('gender', $gender, $selected);
?>

Remove set_value('gender')

How in:

<?php echo form_dropdown('gender', $gender, 'male'); ?>

As Trung mentioned, you can pass an array as the third parameter for multiple selections.

Note that the given value returns the index of the options array ('M' or 'F'), and not the displayed value ('Male' or 'Female'). For lists containing more parameters that are used by two gender groups, I use the primary key of the database table containing the parameters to ensure uniqueness.

Although I’m curious when they first ask me to add “Other” to the list of options for gender ....
