自定义帖子类型ID问题-查询其他帖子类型时 [英] Custom Post Type ID Issue - When Querying Other Post Types
本文介绍了自定义帖子类型ID问题-查询其他帖子类型时的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个非常复杂的问题要解决，这使我感到困惑不已。
I have quite a complex problem to solve which has baffled me for the last day or so.
基本上，我有两个自定义帖子类型会话和食谱。这些在WordPress的后端中可以很好地显示。
Basically, I have two custom post types 'Sessions' and 'Recipes'. These are showing fine in the backend of WordPress.
在会话中附加了几个元框，简介视频，会话视频，目标，健身级别和精选食谱。
Attached to the session are several meta boxes, 'Introduction Video', 'Session video', 'Goals', 'Fitness Level' and 'Featured Recipes'.
精选食谱元框很特殊，因为在其中查询WordPress数据库以获取食谱自定义中的所有帖子帖子类型，然后使用这些值来填充选择框。
The 'Featured Recipes' meta box is special, as in it queries the WordPress database to get all posts within the 'recipe' custom post type and then use these values to populate a select box.
现在，如所附的屏幕截图所示，配方自定义帖子类型的选择框正在拉通过正确的项目和ID，它还会保存数据并拉回正确的选择，并将其与会话帖子类型的正确帖子ID关联。
Now as you can see from the screen shot attached, the select box for the recipe custom post type is pulling through the correct items and ID's, and it also saves the data and pulls back the correct selection and associates it with the correct post ID for the 'session' post type. Great!
问题出在帖子中的其他字段上，他们似乎使用第一个配方ID作为获取每个字段数据的值，而不是而不是会话自定义帖子类型ID。
The problem arises with the other fields within the post, they seem to be using the first recipe ID as the value for pulling through the data for each field, rather than the 'session' custom post type ID.
现在，我可以通过基于特定查询参数编写各种while循环来使其工作，但这会带来另一个问题。数据保存在正确的位置，但是它使用第一个会话 cpt ID来提取所有帖子的数据。
Now I can get this to work by writing various while loops based on specific query arguments but that creates another issue. The data is saved in the correct place but it uses the first 'session' cpt ID to pull back the data for all posts.
现在，我相信这是值得一旦创建了配方元框，就可以将其删除，只要您从functions.php文件中删除此功能及其相关功能，一切就可以正常进行。
Now, I believe it is something to do with the 'recipe' meta box creation, as as soon as you remove this function and it's related functions from the functions.php file, everything works as it should.
我想我应该使用for循环而不是while循环，我现在要尝试一下。
I think I should be using for loops instead of while loops, I'm going to try this now.
希望您中的某些PHP专家能够指出我朝着正确的方向。我已经包含了我的functions.php文件和管理员的屏幕截图。
Hopefully some of you PHP gurus out there will be able to point me in the right direction. I've included both my functions.php file and a screen shot from the admin. Cheers.

I 当然可以使用此功能了，但它并不太正确，因为它要经过相同的标题。
I'm certainly getting closer with this function but it's not quite right as it's pulling through the same title.
function tfp_recipes_html($post) {
// Nonce field for some validation
wp_nonce_field( plugin_basename( __FILE__ ), 'session' );
$recipeArgs = array(
'post_type' => 'recipe'
);
$recipeQuery = get_posts($recipeArgs);
$recipeName = get_post_meta( $post->ID, 'recipe_name', true );
$recipeTitle[] = get_query_var('name');
echo $recipeTitle;
?>
<select name="recipe_names" id="recipes">
<option value="null">Select a Featured Recipe</option>
<?php foreach ( $recipeQuery as $recipe ) : setup_postdata($recipeQuery); ?>
<option id="<?php echo $recipe->ID; ?>" value="<?php echo $recipeTitle; ?>" <?php if($recipeName == $recipeTitle) echo "selected='selected'";?>><?php echo $recipeName; ?></option>
<?php endforeach; ?>
</select>

推荐答案
确定，我使用以下函数解决了我的问题。
OK Guys, I solved my issue using the following function.
function tfp_recipes_html($post) {
// Nonce field for some validation
wp_nonce_field( plugin_basename( __FILE__ ), 'session' );
global $post;
$recipeArgs = array(
'post_type' => 'recipe'
);
$recipes = get_posts($recipeArgs);
$recipeName = get_post_meta( $post->ID, 'recipe_name', true );
?>
<select name="recipe_names" id="recipes">
<option value="null">Select a Featured Recipe</option>
<?php foreach ( $recipes as $recipe ) : setup_postdata($recipe); ?>
<option id="<?php echo $recipe->ID; ?>" value="<?php $recipeTitle = $recipe->post_title; echo $recipeTitle; ?>" <?php if($recipeName == $recipeTitle) echo "selected='selected'";?>><?php echo $recipeTitle; ?></option>
<?php endforeach; ?>
</select>
<?php }
尽管现在我在保存另一个自定义元框时遇到了另一个问题。添加元框的函数是：
Though now I'm having another issue saving another custom metabox. The function to add the metabox is:
function tfp_tips_html($post) {
// Nonce field for some validation
wp_nonce_field( plugin_basename( __FILE__ ), 'session' );
global $post;
echo $post->ID;
$tipArgs = array(
'post_type' => 'tip'
);
$tips = get_posts($tipArgs);
$tipData = get_post_meta( $post->ID, $tipID, true );
foreach ( $tips as $tip ) : setup_postdata($tip);
$tipID = 'tip_' . $tip->ID; ?>
<label for="<?php echo $tipID; ?>">
<input type="checkbox" name="<?php echo $tipID; ?>" id="<?php echo $tipID; ?>" value="1" <?php if ($tipData == 1) echo "checked='checked'"; ?> />
<?php $tipTitle = $tip->post_title; echo $tipTitle; ?>
</label>
<br />
<?php endforeach;
}
与配方功能类似，只不过这会添加每个具有特定ID的复选框。现在保存它的函数是：
Similar to the recipe function except this adds checkboxes each with a specific ID. Now the function to save it is:
function tfp_save_tips($post_id) {
if ( !current_user_can( 'edit_post', $post_id ) ) { return false; }
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
return $post_id;
}
if ( ! wp_verify_nonce( $_POST['custom_post_type'], plugin_basename(__FILE__) ) ) return;
global $tipID;
add_post_meta($post->ID, $tipID, $_POST[$tipID], true) or update_post_meta($post->ID, $tipID, $_POST[$tipID]);
}
问题是它没有保存数据，而是要进入空白页。
The problem is it's not saving the data, and is going to a blank page.
好的，我已经保存了数据，因为以及您返回该帖子时已正确选中的复选框。唯一的问题是它被张贴到空白页上，这是不好的。需要刷新编辑器。
OK, I have the data saving, as well as the checkboxes being checked correctly when you go back to the post. The only issue is it's posting to a blank page, which is no good. Needs to refresh the editor.
现在使用的函数是：
function tfp_save_tips($post_id) {
if ( !current_user_can( 'edit_post', $post_id ) ) { return false; }
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
return $post_id;
}
if ( ! wp_verify_nonce( $_POST['session'], plugin_basename(__FILE__) ) ) return;
$tipArgs = array(
'post_type' => 'tip'
);
$tips = get_posts($tipArgs);
foreach ( $tips as $tip ) : setup_postdata($tip);
$tipID = 'tip_' . $tip->ID;
endforeach;
add_post_meta($post_id, $tipID, $_POST[$tipID], true) or update_post_meta($post_id, $tipID, $_POST[$tipID]);
}
