前端顯示
預設情況下，外掛使用以下過濾器： the_content() 和 the_excerpt()。
使用過濾鉤 OVERRIDE HTML DISPLAY: gklpa_the_postavatar
gklpa_the_postavatar 鉤子接受兩個參數：
$post_avatar_text - 原始 HTML 顯示。
$post_avatar - 帖子頭像數據，以數組格式提供。其密鑰為：
avatar_url：圖像的 URL
show_image_dim：如果為 1，則顯示圖像尺寸；如果為 0，則隱藏圖像尺寸
image_height：圖像高度的整數值或如果關閉圖像尺寸，則為 null
image_width：圖像寬度的整數值或如果關閉圖像尺寸，則為 null
post_id：當前帖子 ID
post_title：圖像屬性的帖子標題
image_name：圖像文件名
示例：如果未選擇頭像，則顯示預設圖像
此示例使用由站點管理員定義的 HTML/CSS 設置。
add_filter( 'gklpa_the_postavatar', 'prefix_show_default_image', 10, 2 );
function prefix_show_default_image( $post_avatar_html, $post_avatar_array ){
global $post, $gklpa_plugin_settings;
// 顯示預設圖像；
if( is_null( $post_avatar_array ) ){
if( !empty( $gklpa_plugin_settings['css_class'] ) {
$css = 'class="' . $gkl_plugin_settings['css_class']. '"';
}
$post_avatar_html = $gklpa_plugin_settings['html_before' ] . '<img '. $css . ' src="http://wplatest.dev/images/default-image.jpg" alt="' . esc_attr(strip_tags($post->post_title) ) . '" />'. $gklpa_plugin_settings['html_after'];
}
return $post_avatar_html;
}

Advanced Customization
For Front End Display
By default, the plugin hooks into the following filters: the_content() and the_excerpt().
OVERRIDE HTML DISPLAY USING FILTER HOOK: gklpa_the_postavatar
The gklpa_the_postavatar filter takes two parameters:
$post_avatar_text – Original HTML display
$post_avatar – Post Avatar data in array format. The keys are:
avatar_url: The URL to the image
show_image_dim: 1 indicates to show image dimensions, 0 to hide them
image_height: integer value of image height or null if image dimensions is turned off
image_width: integer value of image width or null if image dimensions is turned off
post_id: ID of current post
post_title: Post title for the image attribute
image_name: Image file name
Example: Display a default image if no avatar is selected
This example makes use of the HTML/CSS settings defined by the site admin.
add_filter( 'gklpa_the_postavatar', 'prefix_show_default_image', 10, 2 );
function prefix_show_default_image( $post_avatar_html, $post_avatar_array ){
global $post, $gklpa_plugin_settings;
// Display default image;
if( is_null( $post_avatar_array ) ){
if( !empty( $gklpa_plugin_settings['css_class'] ) {
$css = 'class="' . $gkl_plugin_settings['css_class']. '"';
}
$post_avatar_html = $gklpa_plugin_settings['html_before' ] . '
'. $gklpa_plugin_settings['html_after'];
}
return $post_avatar_html;
}
OVERRIDE HTML DISPLAY WITH CUSTOM CONTENT HOOK
If you want to change the HTML completely or override the option to display avatars automatically, use the remove_filter() like so:
remove_filter(‘the_content’, ‘gkl_postavatar_filter’, 99 );
remove_filter(‘the_excerpt’, ‘gkl_postavatar_filter’, 99 );
You can then define your own the_content filter function that makes use of the gkl_postavatar() or gkl_get_postavatar() functions
You will need to use the function gkl_get_postavatar() which takes the post object and returns the array of post avatar information.
$post_avatar_array – Post Avatar data in array format. The keys are:
avatar_url: The URL to the image
show_image_dim: 1 indicates to show image dimensions, 0 to hide them
image_height: integer value of image height or null if image dimensions is turned off
image_width: integer value of image width or null if image dimensions is turned off
post_id: ID of current post
post_title: Post title for the image attribute
image_name: Image file name
Example:
add_filter( 'the_content', 'my_custom_post_avatar' );
function my_custom_post_avatar( $content ){
global $post;
$current_avatar = gkl_get_postavatar( $post );
$html_before = '';
$html_after = '';
// Display default image
if( is_null( $current_avatar ) ) {
$image_url = 'http://wplatest.dev/images/default-image.jpg';
$alt_text = esc_attr(strip_tags($post->post_title) );
} else {
$image_url = $current_avatar['avatar_url'];
$alt_text = $current_avatar['post_title'];
}
$post_avatar_html = $html_before . ''. $html_after;
return $post_avatar_html;
}
OVERRIDE HTML DISPLAY WITH template tag gkl_postavatar
If you want the post avatar to appear outside of the content, e.g. with the entry’s meta information, make use of the gkl_postavatar() template tag.
It takes four paramters:
class: CSS class to use in the `` tag.
before: HTML to appear before the image.
after: HTML to appear after the image.
do_what: Use `echo` to display the post avatar, `return` to pass it to a variable. Defaults to `echo`.
Example: In a template file:
Or you can make your own template tag function like in the example for “Override HTML display with custom content hook”, except you call the function directly in your template instead of hooking into the_content().
For Administration Screens
Add Post Avatar to Pages and Custom Post Types
Use the filter hook gklpa_allowed_post_types to add further post types that you want the Post Avatar selection to appear on.
It takes an array of post type slugs as a parameter.
add_filter( 'gklpa_allowed_post_types', 'prefix_my_custom_post_types' );
function prefix_my_custom_post_types( $current_post_types ){
$current_post_types = array( 'post', 'page', 'review', 'event' );
return $current_post_types;
}
Enable Image Selection for Folder Outside of WordPress Installation
By default, Post Avatar looks for your images folder in relation to your WordPress installation. If you want to move your folder elsewhere, use these pair of filter hooks: gklpa_image_url and gklpa_image_dir. They take a single parameter: Image folder url and absolute path to the image folder, respectively.
add_filter( 'gklpa_image_url', 'prefix_change_folder_url' );
function prefix_change_folder_url( $current_url ){
return esc_url( 'http://mysite.com/images/' );
}
add_filter( 'gklpa_image_dir', 'prefix_change_folder_dir' );
function prefix_change_folder_dir ){
return '/user/public_html/images/';
}
