理想情況下，您希望避免將視頻網址硬編碼到模板文件中。這樣做的「WordPress方式」是爲您的頁面添加一個自定義元框，並將視頻URL添加到該元框，並讓它動態更新您的模板文件。這裏是你如何做到這一點的一個例子。
該代碼可以進入你的孩子爲主題的functions.php文件：
/**
* Calls the class on the post edit screen.
*/
function call_someClass() {
new someClass();
}
if (is_admin()) {
add_action('load-post.php', 'call_someClass');
add_action('load-post-new.php', 'call_someClass');
}
/**
* The Class.
*/
class someClass {
/**
* Hook into the appropriate actions when the class is constructed.
*/
public function __construct() {
add_action('add_meta_boxes', array($this, 'add_meta_box'));
add_action('save_post', array($this, 'save'));
}
/**
* Adds the meta box container.
*/
public function add_meta_box($post_type) {
// Limit meta box to certain post types.
$post_types = array('post', 'page');
if (in_array($post_type, $post_types)) {
add_meta_box(
'some_meta_box_name',
__('Some Meta Box Headline', 'textdomain'),
array($this, 'render_meta_box_content'),
$post_type,
'advanced',
'high'
);
}
}
/**
* Save the meta when the post is saved.
*
* @param int $post_id The ID of the post being saved.
*/
public function save($post_id) {
/*
* We need to verify this came from the our screen and with proper authorization,
* because save_post can be triggered at other times.
*/
// Check if our nonce is set.
if (! isset($_POST['myplugin_inner_custom_box_nonce'])) {
return $post_id;
}
$nonce = $_POST['myplugin_inner_custom_box_nonce'];
// Verify that the nonce is valid.
if (! wp_verify_nonce($nonce, 'myplugin_inner_custom_box')) {
return $post_id;
}
/*
* If this is an autosave, our form has not been submitted,
* so we don't want to do anything.
*/
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return $post_id;
}
// Check the user's permissions.
if ('page' == $_POST['post_type']) {
if (! current_user_can('edit_page', $post_id)) {
return $post_id;
}
} else {
if (! current_user_can('edit_post', $post_id)) {
return $post_id;
}
}
/* OK, it's safe for us to save the data now. */
// Sanitize the user input.
$mydata = sanitize_text_field($_POST['myplugin_new_field']);
// Update the meta field.
update_post_meta($post_id, '_my_meta_value_key', $mydata);
}
/**
* Render Meta Box content.
*
* @param WP_Post $post The post object.
*/
public function render_meta_box_content($post) {
// Add an nonce field so we can check for it later.
wp_nonce_field('myplugin_inner_custom_box', 'myplugin_inner_custom_box_nonce');
// Use get_post_meta to retrieve an existing value from the database.
$value = get_post_meta($post->ID, '_my_meta_value_key', true);
// Display the form, using the current value.
?>
<label for="myplugin_new_field">
<?php _e('Description for this field', 'textdomain'); ?>
</label>
<input type="text" id="myplugin_new_field" name="myplugin_new_field" value="<?php echo esc_attr($value); ?>" size="25" />
<?php
}
}

一旦代碼被加入，你會在你的頁面的後臺發現一個新的元框：
現在在您的模板文件
template-parts/content-home.php中，您可以將代碼修改爲fol低點：
<div class="vimeo-div">
<iframe src="<?php echo get_post_meta($post->ID, '_my_meta_value_key', true) ?>" width="830" height="467" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
</div>
這將允許您只需在需要更改的後端更改後端URL。
您可以將元框值和標題更改爲您需要的任何套件。
也許只是不硬編碼嗎？在FrontPage的編輯器中添加一個字段，並從該輸入中獲取值/ url。在你的主題中迴應這個問題？ – Stender
感謝您的輸入Stender，似乎可行，其他投入也歡迎。 @Stender Wil看看這是否可能。保持更新 –
