Getting “Object of class WP_Post could not be converted to string” - when it is a string
提问by Matanya
I have the following code in my functions.php, which executes a script upon publish:
我的functions.php中有以下代码，它在发布时执行脚本：
function save_new_post($post_ID) {
$site_root = '/home/forexmag/public_html/directory2';
$post = get_post($post_ID);
$title = $post->post_title;
$breaking_news = false;
$categories = get_the_category($post_ID);
if (is_array($categories) && !empty($categories))
{
foreach ($categories as $cat_det)
{
//this is the id for the breaking (bad) news
if (5668 == $cat_det->cat_ID)
{
$breaking_news = true;
break;
}
}
}
$exec_code = "/usr/local/bin/php
$site_root
/crons/cron_notify.php '$title' $post_ID 2 " . intval($breaking_news);
exec(
$exec_code
);
} add_action('draft_to_publish', 'save_new_post', 10, 1);
When I publish a new post I keep getting the following error:
当我发布新帖子时，我不断收到以下错误：
Catchable fatal error: Object of class WP_Post could not be converted to string in /home/forexmag/public_html/wp-content/themes/forex_magnates/functions.php on line 712
This line is where I set the $exec_codevar. However, as you can see, and as I confirmed via var_dump, the $titlevariable is a string. What am I missing?
这一行是我设置$exec_codevar 的地方。但是，正如您所看到的，正如我通过 var_dump 确认的那样，该$title变量是一个字符串。我错过了什么？
EDIT: What's even weirder is that when I var_dump $exec_codeand kill the script, I get a perfect string:
编辑：更奇怪的是，当我 var_dump$exec_code并杀死脚本时，我得到了一个完美的字符串：
string(121) "/usr/local/bin/php /home/forexmag/public_html/directory2/crons/cron_notify.php '2011 Free Forex Report' 9934 2 0"

Got the correct answer on Wordpress Answers. Thought I should share it:
在 Wordpress Answers 上得到了正确答案。认为我应该分享它：
$post_IDis a WP_Postobject. Your exec code should effectively be using $post_ID->ID.
$post_ID是一个WP_Post对象。您的执行代码应该有效地使用$post_ID->ID.
function save_new_post($post_ID)
{
print_r($post_ID);
die();
Returns
退货
WP_Post Object ( [ID] => ...

Do notice that this depends on the hook you are using. E.g if you use publish_pageyou get an integer (This was actually the source of my confusion)
请注意，这取决于您使用的钩子。例如，如果你使用publish_page你会得到一个整数（这实际上是我困惑的根源）

I was getting the same error, however the solution to my problem in the end was
我遇到了同样的错误，但最终我的问题的解决方案是
<?php wp_reset_query(); ?>
This was because WP_Query was being used and was interrupting the rest of the queries further down the page.
这是因为正在使用 WP_Query 并且正在中断页面下方的其余查询。

I got that same error on my website one day but the code wasn't the problem. The problem lies in the database. What I did was go into my database and change the siteurl and home because there was gibberish inside it. I think my website was compromise so I change the database password. This website will help you to get rid of the catchable fatal error https://www.msgdigital.com/catchable-fatal-error-object-of-class-wp_error-could-not-be-converted-to-string/.
有一天我在我的网站上遇到了同样的错误，但代码不是问题。问题出在数据库上。我所做的是进入我的数据库并更改siteurl和home，因为里面有乱码。我认为我的网站受到了威胁，所以我更改了数据库密码。该网站将帮助您摆脱可捕获的致命错误https://www.msgdigital.com/catchable-fatal-error-object-of-class-wp_error-could-not-be-converted-to-string/。
