如何解决我的设置未保存在wordpress主题选项页中
| 我正在尝试基于WordPress的Settings API创建主题选项页面。当我在浏览器中检查options.php页面时(例如http://mysite.com/wordpress/wp-admin/options.php),我看到coolorange_options的条目,但它为空。我在文本字段中添加了网址,宽度和高度后,发生了这种情况。 到目前为止,我已经编写了足够的代码来获取信息并将其存储到数据库中,但没有为任何目的检索它。我在代码顶部的php注释中引用了一个教程。考虑到我不太了解php或编程,这里一定有问题,我只是不知道什么。整个代码如下:<?php
// This options page mainly follows the WordPress Settings API Tutorial at
// http://ottodestruct.com/blog/2009/wordpress-settings-api-tutorial/
add_action(\'admin_menu\',\'theme_admin_add_page\');
add_action(\'admin_init\',\'theme_admin_init\');
function theme_admin_init() {
register_setting(\'coolorange_theme_options\',\'coolorange_options\',\'coolorange_options_validate\');
// what each parameter represents: add_settings_field($id,$title,$callback,$page,$section,$args);
add_settings_section(\'coolorange_logo_main\',\'Logo Section Settings\',\'logo_section_text\',\'coolorange\');
add_settings_field(\'upload_image_button\',\'<strong>Upload logo to the Media Folder</strong>\',\'file_upload_button\',\'coolorange\',\'coolorange_logo_main\'); // Upload Logo button
add_settings_field(\'logo_textfields\',\'<strong>Logo location</strong>\',\'file_location\',\'coolorange_logo_main\'); // logo url,width and height text fields
add_settings_field(\'restore_selectbox\',\'<strong>Restore original heading</strong>\',\'restore_dropdown\',\'coolorange_logo_main\');
}
function logo_section_text() {
echo \'<p>In this section,you can replace the standard blog title heading with a custom logo. The logo cannot be wider than <strong>960 pixels</strong>.</p>\';
}
function file_upload_button() {
$options = get_option(\'coolorange_theme_options\');
echo \'<input id=\"upload_image_button\" class=\"button-secondary\" type=\"button\" name=\"coolorange_theme_options[upload_image_button]\" value=\"Upload Logo\" />\';
}
function file_location() { //opens file_location function
$options = get_option(\'coolorange_theme_options\'); ?>

解决方法
我今天早些时候找到了这个问题的答案。根据教程,我需要确保将每个选项(输入字段,选择框选项等)的名称指定为name = \“ coolorange_options [some_text] \”。我在ID后面命名了some_text部分,例如name = \“ coolorange_options [image_url]。
在本教程中,我在http://ottopress.com/2009/wordpress-settings-api-tutorial/上遵循了较新的版本,每个名称都被php识别为数组。直到我将名称co_restore_selectbox [select_options]更改为coolorange_options [select_options]时,名称才出现在数组中。当我再次在浏览器中检查options.php时,coolorange_options下的条目显示单词SERIALIZED DATA,我认为这意味着该数组已写入options数据库。
