两个或更多ajax调用一个PHP文件

Question

我知道这已被问及我看了其他主题，但无法找到答案。

我有两个ajax调用，指向同一页面。一个删除语言选择，另一个删除教育体验。奇怪的是，在PHP页面上的最后一个查询工作（目前的语言）。编号： 为什么第一个查询不起作用？ （当试图删除教育EXP）

PHP

/*------------------------------------------ 
[NANY EDUCATION EXP DELETE] 
-------------------------------------------*/ 
if(isset($_POST['education_id']) && !empty($_POST['education_id'])){ 
    $education_id = $_POST['education_id']; 
    $stmt = $user_home->runQuery("DELETE FROM user_education WHERE education_id=:education_id"); 
    $stmt->execute(array(':education_id' => $education_id)); 
    $response_array['status'] = 'success'; 
}else{ 
    $response_array['status'] = 'error'; 

} 

/*------------------------------------------ 
[NANY LANGUAGE EXP DELETE] 
-------------------------------------------*/ 
if(isset($_POST['language_id']) && !empty($_POST['language_id'])){ 
    $language_id = $_POST['language_id']; 
    $stmt = $user_home->runQuery("DELETE FROM user_language WHERE language_id=:language_id"); 
    $stmt->execute(array(':language_id' => $language_id)); 
    $response_array['status'] = 'success'; 
}else{ 
    $response_array['status'] = 'error';

的问题是，无论是else条款设置$response_array['status'] = "error";。

他们删除教育时，第一个if区块成功，从教育表删除并设置$response_array['status'] = "success";。然后进入下一个if区块，该区块失败并覆盖$reponse_array['status']。使用elseif来组合它们。

if(!empty($_POST['education_id'])){ 
    /*------------------------------------------ 
    [NANY EDUCATION EXP DELETE] 
    -------------------------------------------*/ 
    $education_id = $_POST['education_id']; 
    $stmt = $user_home->runQuery("DELETE FROM user_education WHERE education_id=:education_id"); 
    $stmt->execute(array(':education_id' => $education_id)); 
    $response_array['status'] = 'success'; 
}elseif(!empty($_POST['language_id'])){ 
    /*------------------------------------------ 
    [NANY LANGUAGE EXP DELETE] 
    -------------------------------------------*/ 
    $language_id = $_POST['language_id']; 
    $stmt = $user_home->runQuery("DELETE FROM user_language WHERE language_id=:language_id"); 
    $stmt->execute(array(':language_id' => $language_id)); 
    $response_array['status'] = 'success'; 
}else{ 
    $response_array['status'] = 'error'; 
} 

BTW，你不需要无论它的设置首先要同时使用isset()和!empty()，因为empty()检查。
