主题面板中的WordPress logo上传选项 _WordPress主题

大家好，我面临一个问题，在我的wordpress主题面板添加logo选项，我使用这个代码

function logo_display() { ?> < input type="file" name="logo" /> < ?php echo get_option('logo'); ?> < ?php } function handle_logo_upload() { if(!empty($_FILES["demo-file"]["tmp_name"])) { $urls = wp_handle_upload($_FILES["logo"], array('test_form' => FALSE)); $temp = $urls["url"]; return $temp; } return $option; } function display_theme_panel_fields() { add_settings_section("section", "All Settings", null, "theme-options"); add_settings_field("logo", "Logo", "logo_display", "theme-options", "section"); register_setting("section", "logo", "handle_logo_upload"); } add_action("admin_init", "display_theme_panel_fields");

问题是它的不保存logo，也不显示在管理以及。我已经尝试了10次不同的方法，但这段代码不工作。请查看这个代码并尝试一下。
#1你忘记在“handle_logo_upload”函数中添加else条件。尝试以下代码:

function logo_display() { ?> < input type="hidden" name="ologo" value="http://www.srcmini.com/< ?php echo get_option('logo'); ?> " readonly /> < input type="file" name="logo" id="imgupload" style="display: none; " /> < a id="OpenImgUpload" class="button button-primary"> Image Upload< /a> < ?php echo get_option('logo'); ?> < ?php } function handle_logo_upload() { if(isset($_FILES["logo"]) & & !empty($_FILES['logo']['name'])) { $urls = wp_handle_upload($_FILES["logo"], array('test_form' => FALSE)); $temp = $urls["url"]; return $temp; } elseif(isset($_FILES["logo"]) & & empty($_FILES['logo']['name'])){ $urls = $_POST["ologo"]; return $urls; } return $option; } function display_theme_panel_fields() { add_settings_section("section", "All Settings", null, "theme-options"); add_settings_field("logo", "Logo", "logo_display", "theme-options", "section"); register_setting("section", "logo", "handle_logo_upload"); } add_action("admin_init", "display_theme_panel_fields");

#2你应该试试这个。希望这对你有帮助。
