    I am using the wp user frontend plugin and I have added some meta_box fields in it which I copied from the theme functions page. the fields look good but I have problem saving them (posting and inserting).

    This is what I have copied:

    global $meta_box, $post;
    $prefix = 'foodpress_';
    
    $meta_box = array(
        'id' => 'meta-box',
        'title' => 'Recipe Info',
        'page' => 'post',
        'context' => 'normal',
        'priority' => 'high',
        'fields' => array(
            array(
                'name' => 'Number of servings',
                'desc' => 'Enter the number of servings (eg. "4")',
                'id' => $prefix . 'servings',
                'type' => 'text',
                'std' => ''
            ),
            array(
                'name' => 'Cooking time',
                'desc' => 'Enter the cooking time (eg. "45 minutes")',
                'id' => $prefix . 'cooking_time',
                'type' => 'text',
                'std' => ''
            ),
            array(
                'name' => 'Ingredients',
                'desc' => 'Enter all the ingredients (eg. "8 ounces dried soba noodles"). <strong>IMPORTANT:</strong> Seperate the ingredients with a single line break',
                'id' => $prefix . 'ingredients',
                'type' => 'textarea',
                'std' => ''
            )
        )
    );  
    
        // Use nonce for verification
        echo '<input type="hidden" name="mytheme_meta_box_nonce" value="', wp_create_nonce(basename(__FILE__)), '" />';
    
        echo '<table class="form-table">';
    
        foreach ($meta_box['fields'] as $field) {
            // get current post meta data
            $meta = get_post_meta($post->ID, $field['id'], true);
    
            echo '<tr>',
                    '<th style="width:20%"><label for="', $field['id'], '"><strong>', $field['name'], ':</strong></label></th>',
                    '<td>';
            switch ($field['type']) {
                case 'text':
                    echo '<input type="text" name="', $field['id'], '" id="', $field['id'], '" value="', $meta ? $meta : $field['std'], '" size="30" style="width:97%" />',
                        '<br /><small>', $field['desc'],'</small>';
                    break;
                case 'textarea':
                    echo '<textarea name="', $field['id'], '" id="', $field['id'], '" cols="60" rows="4" style="width:97%">', $meta ? $meta : $field['std'], '</textarea>',
                        '<br />', $field['desc'];
                    break;
                case 'select':
                    echo '<select name="', $field['id'], '" id="', $field['id'], '">';
                    foreach ($field['options'] as $option) {
                        echo '<option', $meta == $option ? ' selected="selected"' : '', '>', $option, '</option>';
                    }
                    echo '</select>';
                    break;
                case 'radio':
                    foreach ($field['options'] as $option) {
                        echo '<input type="radio" name="', $field['id'], '" value="', $option['value'], '"', $meta == $option['value'] ? ' checked="checked"' : '', ' />', $option['name'];
                    }
                    break;
                case 'checkbox':
                    echo '<input type="checkbox" name="', $field['id'], '" id="', $field['id'], '"', $meta ? ' checked="checked"' : '', ' />';
                    break;
            }
            echo    '<td>',
                '</tr>';
        }
    
        echo '</table>';

    and this are the functions that add the metaboxes in the admin panel for posting:
