but when run file in wordpress admin shows internal server error admin.php?page=visitor_stat/stats-operations.php /blog/wp-admin , doesn't load ajax page

i tried several time , can't find solution. think issue may have correct solution. can me solve issue.

clearly, ajax function url : post not working. in advance solve problem

wordpress environment

first of all, in order achieve task, it's recommended register enqueue jquery script push request server. these operations hooked in wp_enqueue_scripts action hook. in same hook should put wp_localize_script it's used include arbitrary javascript. way there js object available in front end. object carries on correct url used jquery handle.

please take to:

1. wp_register_script(); function
2. wp_enqueue_scripts hook
3. wp_enqueue_script(); function
4. wp_localize_script(); function

add these functions plugin file.

add_action( 'wp_enqueue_scripts', 'so_enqueue_scripts' ); function so_enqueue_scripts(){   wp_register_script( 'ajaxhandle', get_template_directory_uri() . 'path script file', array(), false, true );   wp_enqueue_script( 'ajaxhandle' );   wp_localize_script( 'ajaxhandle', 'ajax_object', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) ); } 

file: jquery.ajax.js

this file makes ajax call.

jquery(document).ready( function($){   //some event trigger ajax call, can push whatever data server, passing "data" object in ajax call   $.ajax({     url: ajax_object.ajaxurl, // object instantiated in wp_localize_script function     type: 'post',     action: 'myaction' // function in functions.php triggered     data:{        name: 'john',       age: '38'     },     success: function( data ){       //do result server       console.log( data );     }   }); }); 

finally on plugin file there should function triggered ajax call. remember suffixes:

1. wp_ajax ( allow function registered users or admin panel operations )
2. wp_ajax_nopriv ( allow function no privilege users )

these suffixes plus action compose name of action:

wp_ajax_myaction or wp_ajax_nopriv_myaction

add_action( 'wp_ajax_myaction', 'so_wp_ajax_function' ); add_action( 'wp_ajax_nopriv_myaction' 'so_wp_ajax_function' ); function so_wp_ajax_function(){   //do whatever want data posted   //to send response have echo result!   echo $_post['name'];   echo $_post['age'];   wp_die(); // ajax call must die avoid trailing 0 in response } 

hope helps!

let me know if not clear.
