UPDATED on 17-Feb-2017
从WordPress 4.4开始,添加了update_term_meta()
和get_term_meta()
函数.这意味着现在我们不必再将数据保存在wp_options
表中,而是将它们存储在wp_termmeta
表中.
As of WordPress 4.4, update_term_meta()
and get_term_meta()
functions have been added. This means that now we don't have to save the data in wp_options
table anymore, rather they are now stored in wp_termmeta
table.
这是我更新的代码.
//Product Cat Create page
function wh_taxonomy_add_new_meta_field() {
?>
<div class="form-field">
<label for="wh_meta_title"><?php _e('Meta Title', 'wh'); ?></label>
<input type="text" name="wh_meta_title" id="wh_meta_title">
<p class="description"><?php _e('Enter a meta title, <= 60 character', 'wh'); ?></p>
</div>
<div class="form-field">
<label for="wh_meta_desc"><?php _e('Meta Description', 'wh'); ?></label>
<textarea name="wh_meta_desc" id="wh_meta_desc"></textarea>
<p class="description"><?php _e('Enter a meta description, <= 160 character', 'wh'); ?></p>
</div>
<?php
}
//Product Cat Edit page
function wh_taxonomy_edit_meta_field($term) {
//getting term ID
$term_id = $term->term_id;
// retrieve the existing value(s) for this meta field.
$wh_meta_title = get_term_meta($term_id, 'wh_meta_title', true);
$wh_meta_desc = get_term_meta($term_id, 'wh_meta_desc', true);
?>
<tr class="form-field">
<th scope="row" valign="top"><label for="wh_meta_title"><?php _e('Meta Title', 'wh'); ?></label></th>
<td>
<input type="text" name="wh_meta_title" id="wh_meta_title" value="<?php echo esc_attr($wh_meta_title) ? esc_attr($wh_meta_title) : ''; ?>">
<p class="description"><?php _e('Enter a meta title, <= 60 character', 'wh'); ?></p>
</td>
</tr>
<tr class="form-field">
<th scope="row" valign="top"><label for="wh_meta_desc"><?php _e('Meta Description', 'wh'); ?></label></th>
<td>
<textarea name="wh_meta_desc" id="wh_meta_desc"><?php echo esc_attr($wh_meta_desc) ? esc_attr($wh_meta_desc) : ''; ?></textarea>
<p class="description"><?php _e('Enter a meta description', 'wh'); ?></p>
</td>
</tr>
<?php
}
add_action('product_cat_add_form_fields', 'wh_taxonomy_add_new_meta_field', 10, 1);
add_action('product_cat_edit_form_fields', 'wh_taxonomy_edit_meta_field', 10, 1);
// Save extra taxonomy fields callback function.
function wh_save_taxonomy_custom_meta($term_id) {
$wh_meta_title = filter_input(INPUT_POST, 'wh_meta_title');
$wh_meta_desc = filter_input(INPUT_POST, 'wh_meta_desc');
update_term_meta($term_id, 'wh_meta_title', $wh_meta_title);
update_term_meta($term_id, 'wh_meta_desc', $wh_meta_desc);
}
add_action('edited_product_cat', 'wh_save_taxonomy_custom_meta', 10, 1);
add_action('create_product_cat', 'wh_save_taxonomy_custom_meta', 10, 1);
用法,以检索数据:
echo $productCatMetaTitle = get_term_meta($term_id, 'wh_meta_title', true);
echo $productCatMetaDesc = get_term_meta($term_id, 'wh_meta_desc', true);
这是代码
//Product Cat creation page
function text_domain_taxonomy_add_new_meta_field() {
?>
<div class="form-field">
<label for="term_meta[wh_meta_title]"><?php _e('Meta Title', 'text_domain'); ?></label>
<input type="text" name="term_meta[wh_meta_title]" id="term_meta[wh_meta_title]">
<p class="description"><?php _e('Enter a meta title, <= 60 character', 'text_domain'); ?></p>
</div>
<div class="form-field">
<label for="term_meta[wh_meta_desc]"><?php _e('Meta Description', 'text_domain'); ?></label>
<textarea name="term_meta[wh_meta_desc]" id="term_meta[wh_meta_desc]"></textarea>
<p class="description"><?php _e('Enter a meta description, <= 160 character', 'text_domain'); ?></p>
</div>
<?php
}
add_action('product_cat_add_form_fields', 'text_domain_taxonomy_add_new_meta_field', 10, 2);
//Product Cat Edit page
function text_domain_taxonomy_edit_meta_field($term) {
//getting term ID
$term_id = $term->term_id;
// retrieve the existing value(s) for this meta field. This returns an array
$term_meta = get_option("taxonomy_" . $term_id);
?>
<tr class="form-field">
<th scope="row" valign="top"><label for="term_meta[wh_meta_title]"><?php _e('Meta Title', 'text_domain'); ?></label></th>
<td>
<input type="text" name="term_meta[wh_meta_title]" id="term_meta[wh_meta_title]" value="<?php echo esc_attr($term_meta['wh_meta_title']) ? esc_attr($term_meta['wh_meta_title']) : ''; ?>">
<p class="description"><?php _e('Enter a meta title, <= 60 character', 'text_domain'); ?></p>
</td>
</tr>
<tr class="form-field">
<th scope="row" valign="top"><label for="term_meta[wh_meta_desc]"><?php _e('Meta Description', 'text_domain'); ?></label></th>
<td>
<textarea name="term_meta[wh_meta_desc]" id="term_meta[wh_meta_desc]"><?php echo esc_attr($term_meta['wh_meta_desc']) ? esc_attr($term_meta['wh_meta_title']) : ''; ?></textarea>
<p class="description"><?php _e('Enter a meta description', 'text_domain'); ?></p>
</td>
</tr>
<?php
}
add_action('product_cat_edit_form_fields', 'text_domain_taxonomy_edit_meta_field', 10, 2);
// Save extra taxonomy fields callback function.
function save_taxonomy_custom_meta($term_id) {
if (isset($_POST['term_meta'])) {
$term_meta = get_option("taxonomy_" . $term_id);
$cat_keys = array_keys($_POST['term_meta']);
foreach ($cat_keys as $key) {
if (isset($_POST['term_meta'][$key])) {
$term_meta[$key] = $_POST['term_meta'][$key];
}
}
// Save the option array.
update_option("taxonomy_" . $term_id, $term_meta);
}
}
add_action('edited_product_cat', 'save_taxonomy_custom_meta', 10, 2);
add_action('create_product_cat', 'save_taxonomy_custom_meta', 10, 2);
使用情况,以检索数据:
$metaArray = get_option('taxonomy_' . $term_id);
echo $productCatMetaTitle = $metaArray['wh_meta_title'];
echo $productCatMetaDesc = $metaArray['wh_meta_desc'];
此代码会出现在您活动的子主题(或主题)的function.php文件中,也可能会出现在任何插件文件中.
所有代码均已通过测试,并且功能齐全.
