PHP显示器

Question

我在MVC中与forloop做斗争。我想从输入文本中传递数据，其中的数据相当于1，2，3，4，5，6，7.-that来自数据库。

我将其传递给控制器，并使用名称为$_POST的text1方法获取数据。这是我的控制器代码

    {
        $template = $this->loadView('view_display');
        if(isset($_POST['check'])):
            $text1= $_POST['text1'];
            $text1= explode(',', $text1);
            foreach($text1 as $text1):
            $rem = $this->Faculty_model->testFunction($this->security_plugin->cleanInput($text1));
            $template->set(['stud' => $rem, 'username' => $this->session_helper->get('username'), 'security'=> $this->security_plugin, 'url' => $this->url_helper]);
            endforeach;
        endif;
        $this->security_plugin->CSRFToken();
        $template->render();

这是我的模型

    {
        $sql="select * from table where id=:text1";
        $bind = array(
            ':text1' => $text1
        );
        $data = $this->db->fetchAll($sql, $bind);
        return $data;
    }

这就是我的观点

<?php if(!empty($stud)): ?>
<?php foreach($stud as $stud): ?>
<?php echo $security->SanitizeString($stud->ID); ?>
<?php echo $security->SanitizeString($stud->NAME); ?>
<?php echo $security->SanitizeString($stud->AGE); ?>

问题是它将只显示text1文本框中的最后一个数字。我搞不懂。

任何帮助都很感谢:)

1.您需要在$rem之前将foreach()定义为数组，然后进行值的赋值。

2.将$template->set()代码放在foreach()之外

$template = $this->loadView('view_display');
if(isset($_POST['check'])):
    $text1= $_POST['text1'];
    $text1= explode(',', $text1);
    $rem = [];
    foreach($text1 as $text1):
    $rem[] = $this->Faculty_model->testFunction($this->security_plugin->cleanInput($text1));
    endforeach;
    $template->set(['stud' => $rem, 'username' => $this->session_helper->get('username'), 'security'=> $this->security_plugin, 'url' => $this->url_helper]);
endif;

$this->security_plugin->CSRFToken();
$template->render();
