in the documentation it says that you can have an array in the name field.
Code:
<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />but i dont get why u would do that. could someone explain?

I use an array in my forms to group data (for different database tables), like an user and settings:
Code:
<input type="text" name="user[name]" />
<input type="text" name="user[email]" />
<input type="text" name="user_settings[language]" />
<input type="text" name="user_settings[group]" />I can now access only the user data very easily trough:
Code:
$this->input->post('user'); // array('name', => 'value', 'email' => 'value')And the settings
Code:
$this->input->post('user_settings'); // array('language' => 'value', 'group' => 'value')an array in name field in a form? - El Forum - 04-11-2010
