如何在编辑类别管理 wordpress 中添加元数据框?
How to add a metabox in edit category admin wordpress?
我正在尝试,但如果我成功使用 add_meta_box()
我有以下代码:
function myplugin2_add_meta_box() {
$screens = array( 'category', 'page' );
foreach ( $screens as $screen ) {
add_meta_box(
'cat',
__( 'Scroll infinito', 'myplugin2_textdomain' ),
'myplugin2_meta_box_callback',
$screen,
'side'
);
}
}
add_action( 'add_meta_boxes', 'myplugin2_add_meta_box', 2 );
function myplugin2_meta_box_callback(){
global $post;
$custom = get_post_custom($post->ID);
?>
<label>Activar</label>
<?php
}
您可以试试这个代码。希望,努力吧。
<?php
function wp_category_fields($term) {
$short_description = get_term_meta($term->term_id, 'short_description', true);
$color_code = get_term_meta($term->term_id, 'color_code', true);
?>
<tr class="form-field">
<th valign="top" scope="row"><label for="term_fields[short_description]"><?php _e('Short description'); ?></label></th>
<td>
<textarea class="large-text" cols="50" rows="5" id="term_fields[short_description]" name="term_fields[short_description]"><?php echo esc_textarea($short_description); ?></textarea><br/>
<span class="description"><?php _e('Please enter short description'); ?></span>
</td>
</tr>
<tr class="form-field">
<th valign="top" scope="row"><label for="term_fields[color_code]"><?php _e('Color code'); ?></label></th>
<td>
<input type="text" size="40" value="<?php echo esc_attr($color_code); ?>" id="term_fields[color_code]" name="term_fields[color_code]"><br/>
<span class="description"><?php _e('Please enter color hex code'); ?></span>
</td>
</tr>

// Add the fields, using our callback function
