Question

我正在从数据库字段创建一个表单，所以我拉出所有记录并循环并在php中的foreach循环中添加表单元素。问题是，当我提交表单时，元素未发布，我得到的唯一回报是提交按钮： -

stdClass Object
(
    [submitbutton] => Submit
)

这是我创建元素的方式，这些都在屏幕上正确显示和完成，它只是在我提交时不发布，但是如果我在foreach循环中没有它们，则元素会发布，但我需要创建他们动态地从数据库，任何想法？

foreach($records as $log){
    $inc++;

    if($log->type == 0){ 

        $mform->addElement('html', '<p>'.$log->leadin.'</p>');

        $attributes = array();
        $distractors = explode(',', $log->distractors);
        $radioarray=array();
        $count = 0;

        foreach($distractors as $dis){
            $count++;
            $radioarray[] =& $mform->createElement('radio', 'radio', '', $dis, $count, array());
        }

        $mform->addGroup($radioarray, 'radioar'.$inc, '', array(' '), false);
    }
    else if($log->type == 1){

        $mform->addElement('html', '<div>'.$log->leadin.'</div>');

        $distractors = explode(',', $log->distractors);
        $count = 0;

        foreach($distractors as $dis){
            $count++;
            $mform->addElement('checkbox', 'check'.$count, $dis);
        }
    }}

以下是上述代码输出的图像，所有显示和功能都正确。

使用此代码，也可以在此表单中添加提交按钮

<form autocomplete="off" action="blocks/training_plan/student/survey.php" method="post" accept-charset="utf-8" id="mform1" class="mform">
    <?php
        foreach($records as $log){
        $inc++;

        if($log->type == 0){ 

            $mform->addElement('html', '<p>'.$log->leadin.'</p>');

            $attributes = array();
            $distractors = explode(',', $log->distractors);
            $radioarray=array();
            $count = 0;

            foreach($distractors as $dis){
                $count++;
                $radioarray[] =& $mform->createElement('radio', 'radio', '', $dis, $count, array());
            }

            $mform->addGroup($radioarray, 'radioar'.$inc, '', array(' '), false);
        }
        else if($log->type == 1){

            $mform->addElement('html', '<div>'.$log->leadin.'</div>');

            $distractors = explode(',', $log->distractors);
            $count = 0;

            foreach($distractors as $dis){
                $count++;
                $mform->addElement('checkbox', 'check'.$count, $dis);
            }
        }}
    ?>
</form>

解决了！我发现首次加载页面时我在URL中传递的额外参数以及首次创建表单时还需要在提交表单时存在，因此url上的额外参数搜索数据库记录，以及何时我提交了表单，页面被重新加载，所有函数再次被调用并失败，因为缺少参数并且找不到记录。希望这有助于其他人。
