플러그인 클래스 파일에서 Ajax URL 호출 :
function __construct() { add_shortcode("user_registration_form", array($this, "shortcode")); } public function hook(){ add_action( "wp_ajax_get_product_serial_callback", "get_product_serial_callback" ); add_action( "wp_ajax_nopriv_get_product_serial_callback", "get_product_serial_callback" ); } public function product_serial_ajax() { ?> <script type="text/javascript"> jQuery(document).ready(function(){ alert("Hello World!"); jQuery.ajax({ type: "GET", url: "<?php echo admin_url("admin-ajax.php"); ?>", //url: ajaxurl, dataType : "JSON", data : {action: "get_product_serial_callback"}, //cache: false, success: function(data){ alert("Eureka")"; } }); }); </script><?php } function csv_to_array($filename="", $delimiter=",") { //if(!file_exists($filename) || !is_readable($filename)) //return FALSE; $header = NULL; $data = array(); if (($handle = fopen($filename, "r")) !== FALSE) { while (($row = fgetcsv($handle, 1024, $delimiter)) !== FALSE) { if(!$header) $header = $row; else $data[] = array_combine($header, $row); } fclose($handle); } return $data; } function get_product_serial_callback(){ $upload_dir = wp_upload_dir(); $csvFile = $upload_dir["baseurl"]."/Eragon-Serial.csv"; $csv = $this->csv_to_array($csvFile); //read csv foreach ($csv as $serialnum){ $serial_num_array[] = $serialnum["product_serial"]; } $json_array = json_encode($serial_num_array); echo $json_array; die(); } function shortcode() { $this->product_serial_ajax();//fetch product serial number }
하지만 ajaxurl가 정의되지 않은 경우 아래 URL의 형식
http://example.com/wp-admin/admin-ajax.php?action=get_product_serial_callback
이 도 도움이되지 않았습니다. .
get_product_serial_callback 함수를 호출하여 JSON 값을 가져오고
?
설명
Answer
_construct () 함수에 코드를 입력하고 작업 이름을 get_product_serial_callback으로 변경 :-
add_action( "wp_ajax_get_product_serial_callback", array($this,"get_product_serial_callback") ); add_action( "wp_ajax_nopriv_get_product_serial_callback", array($this,"get_product_serial_callback" ));

플러그인 클래스 파일 :

개별 JS 파일
function load_product(){ jQuery.ajax({ type: "GET", url: ajaxurl, dataType : "JSON", data : {action: "get_product_serial"}, //cache: false, success: function(data){ alert("Eureka"); } }); }
PS : 내 테마의 header.php에 다음을 입력하면 효과가있었습니다.
<script type="text/javascript"> var ajaxurl = "<?php echo admin_url("admin-ajax.php"); ?>"; </script>
array($this, 'get_product_serial_callback')이어야합니다.ajaxurl is not defined
