set_value()

set_value($field[, $default = ''[, $html_escape = TRUE]])

Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function. The second (optional) parameter allows you to set a default value for the form. The third (optional) parameter allows you to turn off HTML escaping of the value, in case you need to use this function in combination with i.e. form_input() and avoid double-escaping.

Example:

<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />

The above form will show “0” when loaded for the first time.
