LX Adjust Field

Released 3 years ago , Last update 3 years ago

An easy way to create "adjust fields" in your forms - numeric values that can be adjusted (increased and decreased) dynamically using plus and minus buttons.

LX Adjust Field is an adjustable numeric value that uses familiar UI from games and application (plus / minus buttons). It can be assigned a pool of points and other restrictions.

Example Code

Requires: jQuery.

How to use it:

  1. Link to the form_helper.js file.
  2. Add the MYformhelper.php file to your CodeIgniter helpers folder.
  3. Load the form helper class as you would normally using this line:

    $this->load->helper('form');

  4. After that, you can add the adjust field by using the line echo form_adjust($name, $starting_value, $is_numeric, $point_increment, $value_increment, $min, $max ); The only required values are the $name and $starting_value.

  5. If you wish to display a "Point pool" you must add a label with id pointsleft, and if you wish said point pool to be submitted, you may also add a hidden input with id pointsleft in your markup. Example:

    and

Parameters:

  • $name => The name and id attributes of the input containing the value
  • $starting_value => The value from where the counting starts. You can also set a character as a $starting value, just make sure the next property is set to true.
  • $is_numeric => If true, the values will increase and decrease as numbers, else they will adjust as characters. Default value is true.
  • $point_increment => This sets how many points will be substracted/added from/to the point pool on each click. Default value is 1.
  • $value_increment => This input sets the amount of points added/substracted to the field value on each click. Default value is 1.

  • $min => No matter how much you click the "minus" button, the value will not go below this value. Default value is -1000. Can also be a character.

  • $max => Same thing... Default value is 1000 and can also be a character.
