[Plugin: OptionTree] Feature request – subheader / value/unit-selector

Hey, if anyone is interested, I made a couple of changes to the code to get a value-unit datatype – that is turning a value-unit pair into an array when being saved into the options table and adding a form element to display and change the value-unit pair. Maybe there’s a better way to do it, but it works for me…

a) new form element ‘valueunit’ as new file ‘valueunit.php’ in [plugin_root]/functions/admin/

This file is displaying a simple combined element of input and select box. The two elements are then saved as variables with the valueunit-key and the respective suffix “_value” and “_unit”.

<?php if (!defined('OT_VERSION')) exit('No direct script access allowed');
/**
 * Input Option
 *
**/

function option_tree_valueunit( $value, $settings, $int )
{
?>
  <div class="option option-valueunit">
    <h3><?php echo htmlspecialchars_decode( $value->item_title ); ?></h3>
    <div class="section">
      <div class="element">
        <input type="text" name="<?php echo $value->item_id; ?>_value" id="<?php echo $value->item_id; ?>_value" value="<?php if ( isset($settings[$value->item_id]) ) { echo htmlspecialchars( stripslashes( $settings[$value->item_id[0]] ), ENT_QUOTES); } ?>" />

         <div class="select_wrapper">
            <select name="<?php echo $value->item_id; ?>_unit" class="select unit">
                <?php
                echo '<option value="">-- Choose One --</option>';
            	$units = array(
                    'px' => 'px',
                    '%'  => '%',
                    'em' => 'em',
                    'pt' => 'pt'
		);

		foreach ( $units as $unit )
                {
            	    $selected = '';
  	            if ( $settings[$value->item_id[1]] == trim( $unit ) )
  	                 { $selected = ' selected="selected"'; }

		          echo '<option'.$selected.'>'.trim( $unit ).'</option>';
       			} 

		?>
          </select>
        </div>

	  </div>
      <div class="description">
        <?php echo htmlspecialchars_decode( $value->item_desc ); ?>
      </div>
    </div>
  </div>
<?php
}

b) changes made to [plugin_root]/functions/functions_load.php ->
include the new form part. This is to load the new form part in the options panel.

include( 'admin/valueunit.php' );

at the appropriate position.

c) changes made to [plugin_root]/admin/settings.php ->
display the new option-type in the select box in the settings form.
Added a new array element in the types-array after ca. line 113.

'valueunit' => 'ValueUnit',

d) changes made to [plugin_root]/classes/class.admin.php -> function option_tree_array_save. Added an else-if condition checking for the new option type “valueunit” and then taking the value-unit pair sent and write it into an array using the single original key after ca. line 491.

else if ($value->item_type == "valueunit" ) {
      	$key = trim( $value->item_id );
        $tempkeys = array('_value', '_unit');

        foreach ($tempkeys as $tempkey) {
			$value[]=$_REQUEST[$key.$tempkey];
		}	

		$new_settings[$key] = $value
      	}

Looks promising, I’ll look over the code now and include it in the new update today if everything is working correctly. Thanks for your contribution.

It’s been added and the code was updated slightly. I’ll push it to the live server later today with the other updates.
