使用Ajax調用WordPress過濾器動作

Question

我使用的是用於WordPress的Give插件。他們有一個概念驗證插件，允許在結帳時添加費用https://github.com/WordImpress/Give-Snippet-Library/blob/master/form-customizations/basic-fees.php

這種方式按預期方式工作，並沒有問題，但我想要做的是使費用可選，以便捐助者可以選擇前端是否要增加這筆費用。

下面是創建新的捐贈大寫金額的部分代碼：

function give_basic_fees_add_fee($sanitized_amount) { 
    $fee_percentage = (int) give_get_option('basic_fee_percentage'); 
    $fee   = $sanitized_amount * ($fee_percentage/100); 
    $new_total  = $fee + $sanitized_amount; 
    return $new_total; 
} 
add_filter('give_donation_total', 'give_basic_fees_add_fee', 1, 1); 

我試圖做的是用Ajax調用它。我試過以下，這是行不通的：

JS：

//... 
//Use Ajax to see if user checked fee box before submitting 
//I've already confirmed this part of the script is loading in the footer. 
      function check_for_fees(){ 
       var checked; 
       if($('#gateway-fee').is(':checked')){ 
        checked=true; 
       } 
       else { 
        checked=false; 
       } 
       var data = { 
        'action': 'give_basic_fees_add_fee', 
        'checked': checked 
       } 
       $.post(ajaxurl, data, function(response) { 
        alert('Got this from the server: ' + response); 
       }); 
      } 

PHP：

add_action('wp_axaj_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); 
add_action('wp_axaj_nopriv_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); 
function give_basic_fees_add_fee($sanitized_amount) { 

    /*I just want to alert "Checked" so I know it's working, and create 
    additional conditional code depending on the value of "checked".*/ 
    $checked  = intval($_POST['checked']); 
    echo $checked; 

} 

Answer 1

您的代碼中存在拼寫錯誤，這應該是它不起作用的原因。

代替打字

add_action('wp_axaj_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); add_action('wp_axaj_nopriv_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); 

型：適合於Ajax調用

add_action('wp_ajax_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); 
add_action('wp_ajax_nopriv_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); 

WordPress默認前綴是wp_ajax，不wp_axaj。

嗨嘗試這可能會幫助你。

add_action('wp_axaj_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); 
add_action('wp_axaj_nopriv_give_basic_fees_add_fee', 'give_basic_fees_add_fee'); 
function give_basic_fees_add_fee() { 
    /*I just want to alert "Checked" so I know it's working, and create 
    additional conditional code depending on the value of "checked".*/ 
    $checked  = intval($_POST['checked']); 
    echo $checked; 
//<b>Add exit here otherwise it will give zero along with response.</b> 
exit; 
}
