form_dropdown helper --> disabled option - Islam Sharaf - 02-13-2016

Hello,

I can't mark specific options as disabled because no way to do it.

Code:
<option value="1" disabled> ddddd</option>


I tried to add it in options array by add the disabled attribute beside the value eg. :

PHP Code:
$options = array( 'small" disabled' => ''small shirt"); 


Also i tried :

PHP Code:
$options = array( 'small" disabled = "disabled' => ''small shirt"); 


But the problem with html_entities it converts the double quote to the entity : &quote


form_dropdown([$name = ''[, $options = array()[, $selected = array()[, $extra = '']]]])

I'm looking forward to something like that:

form_dropdown([$name = ''[, $options = array()[, $selected = array()[, $extra = '', $disabled_options = array()]]]]])

If there is an extra option called $disabled_options = array() it would be great.

You can create your own MY_form_helper.php.
Put your form_dropdown() function inside this php file.
It will override the standard form_dropdown() function.

Create custom dropdown function inside the application/helpers/MY_helper.php, and autoload your new helper.

PHP Code:
function my_form_dropdown($data = '', $options = array(), $selected = array(), $disabled = array(), $hidden= array(), $extra = '')
{
    $defaults = array();

    if (is_array($data))
    {
        if (isset($data['selected']))
        {
            $selected = $data['selected'];
            unset($data['selected']); // select tags don't have a selected attribute
        }

        if (isset($data['options']))
        {
            $options = $data['options'];
            unset($data['options']); // select tags don't use an options attribute
        }

        if (isset($data['disabled']))
        {
            $disabled = $data['disabled'];
            unset($data['disabled']); // select tags don't use an disabled attribute
        }

        if (isset($data['hidden']))
        {
            $hidden = $data['hidden'];
            unset($data['hidden']); // select tags don't use an hidden attribute
        }
    }
    else
    {
        $defaults = array('name' => $data);
    }

    is_array($selected) OR $selected = array($selected);
    is_array($options) OR $options = array($options);
    is_array($disabled) OR $disabled = array($disabled);
    is_array($hidden) OR $hidden = array($hidden);

    // If no selected state was submitted we will attempt to set it automatically
    if (empty($selected))
    {
        if (is_array($data))
        {
            if (isset($data['name'], $_POST[$data['name']]))
            {
                $selected = array($_POST[$data['name']]);
            }
        }
        elseif (isset($_POST[$data]))
        {
            $selected = array($_POST[$data]);
        }
    }

    $extra = _attributes_to_string($extra);

    $multiple = (count($selected) > 1 && stripos($extra, 'multiple') === FALSE) ? ' multiple="multiple"' : '';

    $form = '<select '.rtrim(_parse_form_attributes($data, $defaults)).$extra.$multiple.">\n";

    foreach ($options as $key => $val)
    {
        $key = (string) $key;

        if (is_array($val))
        {
            if (empty($val))
            {
                continue;
            }

            $form .= '<optgroup label="'.$key."\">\n";

            foreach ($val as $optgroup_key => $optgroup_val)
            {
                $sel = in_array($optgroup_key, $selected) ? ' selected="selected"' : '';
                $dis = in_array($optgroup_key, $disabled) ? ' disabled' : '';
                $hid = in_array($optgroup_key, $hidden) ? ' hidden' : '';
                $form .= '<option value="'.html_escape($optgroup_key).'"'.$sel.$dis.$hid.'>'
                    .(string) $optgroup_val."</option>\n";
            }

            $form .= "</optgroup>\n";
        }
        else
        {
            $form .= '<option value="'.html_escape($key).'"'
                .(in_array($key, $selected) ? ' selected="selected"' : ''). (in_array($key, $disabled) ? ' disabled': ''). (in_array($key, $hidden) ? ' hidden': '').'>'
                .(string) $val."</option>\n";
        }
    }

    return $form."</select>\n";
} 

It is the same as the core form_dropdown() function but with two new arguments ([array] disabled) , ([array] hidden):

Usage:
PHP Code:
$data = ['name' => 'countries', class='form-control'];
$options = [
 '' => '-Select Country-',
 'burundi' => 'Burundi',
 'comoros' => 'Comoros',
 'congo' => 'D.R Congo'
];
 echo my_form_dropdown($data, $options, '', '', '');
