Podem me mostrar alguma maneira de fazer upload de logo através do Pai

[leoamrl 0]

Estou trabalhando no desenvolvimento de um theme wordpress do zero e estou colocando uma página de "Theme Settings" nesse theme, para alterar coisas como a logo, links de ícones, copyright etc.

Para fazer o Painel segui esse tutorial: http://wpmidia.com.br/tutoriais/tutorial-wordpress-como-criar-abas-em-sua-theme-options-page

 

Preciso de um código HTML para colocar no Theme Settings em que eu possa fazer o upload de uma imagem, e armazenar no wordpress para que seja usada como logo.

 

Meu código está assim:

 

Arquivo adminsettings.php

<?php


add_action( 'init', 'wptester_admin_init' );
add_action( 'admin_menu', 'wptester_settings_page_init' );

function wptester_admin_init() {
	$settings = get_option( "wptester_theme_settings" );
	if ( empty( $settings ) ) {
		$settings = array(
			'wptester_intro' => 'Some intro text for the home page',
			'wptester_tag_class' => false,
			'wptester_ga' => false
		);
		add_option( "wptester_theme_settings", $settings, '', 'yes' );
	}	
}

function wptester_settings_page_init() {
	$theme_data = get_theme_data( TEMPLATEPATH . '/style.css' );
	$settings_page = add_theme_page( $theme_data['Name']. ' Theme Settings', $theme_data['Name']. ' Theme Settings', 'edit_theme_options', 'theme-settings', 'wptester_settings_page' );
	add_action( "load-{$settings_page}", 'wptester_load_settings_page' );
}

function wptester_load_settings_page() {
	if ( $_POST["wptester-settings-submit"] == 'Y' ) {
		check_admin_referer( "wptester-settings-page" );
		wptester_save_theme_settings();
		$url_parameters = isset($_GET['tab'])? 'updated=true&tab='.$_GET['tab'] : 'updated=true';
		wp_redirect(admin_url('themes.php?page=theme-settings&'.$url_parameters));
		exit;
	}
}

function wptester_save_theme_settings() {
	global $pagenow;
	$settings = get_option( "wptester_theme_settings" );
	
	if ( $pagenow == 'themes.php' && $_GET['page'] == 'theme-settings' ){ 
		if ( isset ( $_GET['tab'] ) )
	        $tab = $_GET['tab']; 
	    else
	        $tab = 'homepage'; 

	    switch ( $tab ){ 
	        case 'general' :
				$settings['wptester_tag_class']	  = $_POST['wptester_tag_class'];
			break; 
	        case 'footer' : 
				$settings['wptester_ga']  = $_POST['wptester_ga'];
			break;
			case 'homepage' : 
				$settings['wptester_intro']	  = $_POST['wptester_intro'];
			break;
	    }
	}
	
	if( !current_user_can( 'unfiltered_html' ) ){
		if ( $settings['wptester_ga']  )
			$settings['wptester_ga'] = stripslashes( esc_textarea( wp_filter_post_kses( $settings['wptester_ga'] ) ) );
		if ( $settings['wptester_intro'] )
			$settings['wptester_intro'] = stripslashes( esc_textarea( wp_filter_post_kses( $settings['wptester_intro'] ) ) );
	}

	$updated = update_option( "wptester_theme_settings", $settings );
}

function wptester_admin_tabs( $current = 'homepage' ) { 
    $tabs = array( 'homepage' => 'Home', 'general' => 'General', 'footer' => 'Footer' );
