我正在尝试查询数据库并返回一个数字以存储在名为 node--course.html.twig
的树枝模板中因此,我首先在类 FormaRegis.php
中编写函数 completionCheck()<?php
namespace Drupal\docebo_login;
use Drupal\docebo_login\FormaEntity;
class FormaRegis extends FormaEntity {
public $ID;
public function setID($ID) {
$this->ID = $ID;
}
public function getID() {
return $this->ID;
}
public function __construct() {
parent::__construct();
}
public function rowBase() {
if (parent::accessCheck()) {
$sql = "SELECT * FROM learning_courseuser
WHERE idUser = " . $_SESSION['public_area_idst'] .
" AND idCourse = " . $this->ID. " ";
return $sql;
} else {
return "";
}
}
public function completionCheck() {
$check = false;
if (parent::accessCheck()) {
$sql = "SELECT count(*) FROM learning_courseuser
WHERE DATE_FORMAT(CURDATE(),'%d/%m/%Y') = DATE_FORMAT(date_complete,'%d/%m/%Y')
AND idUser = " . $_SESSION['public_area_idst'];
return $sql;
}
else {
return "";
}
}
}
在一个名为 FormaEntity.php 的页面中,我编写了此函数
public function getCCresult() {
if ($this->completionCheck() == "") {
\Drupal\Core\Database\Database::setActiveConnection();
return false;
}
$result = $this->connection->query($this->completionCheck())->fetch();
\Drupal\Core\Database\Database::setActiveConnection();
if ($result > 5 ) {
$check = "fail";
}
else {
$check = "pass";
}
return $check;
}
然后在 FormaNotification.php 中,我编写了函数 completionCheck()
<?php
namespace Drupal\docebo_login;
use Drupal\docebo_login\FormaEntity;
class FormaNotification extends FormaEntity {
public function __construct() {
parent::__construct();
}
public function getResult() {
return parent::accessCheck();
}
public function completionCheck() {
return parent::getCCresult();
}
}
然后,最后,在我的.theme文件中,添加了函数 mytheme_preprocess_node_course(&$ variables)
function mytheme_preprocess_node_course (&$variables) {
$noti = new FormaNotification();
if ($noti->completionCheck() == "fail") {
$variables['creditCheck'] = "yes";
}
else {
$variables['creditCheck'] = "no";
}
}
但是当我访问使用该节点的任何页面--course.html.twig并使用 {{kint(creditCheck)}} ,它表示该变量为NULL。我不确定自己在做什么错。如果有人能指出我正确的方向,那就太好了。
