@rynald0s My gmail didn’t received any mail

If I downloaded and installed manually, it displayed error, Plugin could not be activated because it triggered a fatal error., when I activated it.

@sebastienserre Is your mean letting the code init not callback again by if condition?
If it is what I say, how does write the condition of if?

@bcworkz Thanks for your suggestion.
But it becomes to produce three posts after reload every times…

@weboccults Thank you very much!!
It work!!

Thanks for everybody answer!!!

I understand the reason about adding too much posts using init.
But I don’t know why do I add some checks at start of the function.
Dose it help us solve problem?
why?
and how to do specifically?
do you have try it?
Or do you have another suggestion for adding new post using hook or any way?

Thank for your answer, but this problem still wasn’t solve after I modified my code.
add_action('init', 'example_function');->add_action('plugins_loaded', 'example_function');

First time reloading, adding a new post.
Second time reloading, adding another 3 new posts.
Third time reloading, adding 4 new posts……

Thank you very very very much!

Thank for your advise, but I got error after I move my code.
The error:
Fatal error: Uncaught Error: Class 'Test_one' not found in D:\Appserv\Apache24\htdocs\php7.4\wordpress\wp-content\plugins\crawler\crawler.php:160 Stack trace: #0 D:\Appserv\Apache24\htdocs\php7.4\wordpress\wp-includes\shortcodes.php(356): Test->shortcode_value('', '', 'current_year') #1 [internal function]: do_shortcode_tag(Array) #2 D:\Appserv\Apache24\htdocs\php7.4\wordpress\wp-includes\shortcodes.php(228): preg_replace_callback('/\\[(\\[?)(curren...', 'do_shortcode_ta...', '\n<p>123456789</...') #3 D:\Appserv\Apache24\htdocs\php7.4\wordpress\wp-includes\class-wp-hook.php(303): do_shortcode('\n<p>123456789</...') #4 D:\Appserv\Apache24\htdocs\php7.4\wordpress\wp-includes\plugin.php(189): WP_Hook->apply_filters('\n<p>123456789</...', Array) #5 D:\Appserv\Apache24\htdocs\php7.4\wordpress\wp-includes\post-template.php(253): apply_filters('the_content', '<!-- wp:paragra...') #6 D:\Appserv\Apache24\htdocs\php7.4\wordpress\wp-content\themes\twentytwentyone_test\template-parts\content\content-single.php(23): the_content()

The code1 (moving tojs2php_register()):

function js2php_register(){
        require_once plugin_dir_url(__FILE__) . 'src/ming_crawler.php';
        add_action( 'wp_ajax_crawler_info', array($this, 'get_info') );
        add_action( 'wp_ajax_nopriv_crawler_info', array($this, 'get_info') );
        add_shortcode( 'current_year', array($this, 'salcodes_year') );
        
    }

OR

The code2 (moving to__construct()):

function __construct()
    {
       require_once plugin_dir_url(__FILE__) . 'src/ming_crawler.php';
    }

No matter which I move to code1 or code2, I got same error.
Could you help me, thanks

I got this error after moving the code withinjs2php_register()

I got this error after moving the code within a constructor function of Test

$test = new Test;
$test->js2php_register();

So….how do I fix this question?
Thank you

@bcworkz
1. I found $this->val can’t work in the function of add_action or add_shortcode in the same class.
Therefore, $my_crawler = new Test_one($infos); should change to $my_crawler = new Test_one(get_option('my_val'));

2. I get error Fatal error: Uncaught Error: Class ‘Test_one’ not found when I run my code.
The following is my_test1.php:

<?php
class Test_one{
    function a(){
        $this->a1='aaa';
    }
    function b(){
        echo 'a1:'.$this->a1;
    }
    function c(){
        $this->a();
        $this->b();
    }
}

3. my file directory:
The class of Test is in my_plugin_name.php

my_plugin_name—assets
| |
| —js
| |
| –app.js
|
—src
| |
| –my_test1.php
|
|
—my_plugin_name.php

@bcworkz No, I mean display value using PHP, not JS.
First, our discuss base on wordpress plugin, so we can display value on plugin page using php’s echo.
Second, the process is the following
html value –1–> JS get this value –2–> JS delivers this value using ajax–3–> php gets this value using wp_ajax_ –4–> displaying this value using php echo (This means php gets this value truly, and then I can handle this value or doing another testing)

Another word, I don’t know how to modify your code to the 4th step.

@bcworkz I know what you said, and thank for your explain.
but my main problem is how to display echo the vale on the frontend of admin or wp after ajax deliver it.

@bcworkz Thanks for your explain, but I more want to how to get value in php from ajax not only get value in $ajax.do.
Do you know how to get?
