最初我不在moodle form
中使用cancel
按钮。我的表格看起来像:
require_once("{$CFG->libdir}/formslib.php");
class quest_form extends moodleform {
function definition() {
global $DB;
$mform =&$this->_form;
$mform->addElement('header','displayinfo', 'Add Question');
// add question.
$mform->addElement('editor', 'title', 'Question');
$mform->addRule('title', null, 'required', null, 'client');
$mform->setType('title', PARAM_RAW);
// add answer.
$mform->addElement('editor', 'answer', 'Answer');
$mform->addRule('answer', null, 'required', null, 'client');
$mform->setType('answer', PARAM_RAW);
$mform->addElement('hidden', 'blockid');
$mform->setType('blockid', PARAM_RAW);
$mform->addElement('hidden', 'courseid');
$mform->setType('courseid', PARAM_RAW);
$this->add_action_buttons(false, 'submit');
}
现在我想在我的表单中使用cancel
按钮,所以我替换了行
$this->add_action_buttons(false, 'submit');
带有
$this->add_action_buttons(true, 'submit');
成功显示cancel
按钮,但同时单击cancel
按钮the form gets submitted
(即使表单字段中没有数据(。
我该如何解决此问题?我还错过了什么吗??
请帮帮我…

取决于Russell England的答案。我试着如下:
$qform = new quest_form ();
if ($qform ->is_cancelled()){
redirect("view.php?id={$cid}");
}else{
$qform = new pool_form("pool_action.php?id={$cid}&qpid={$questplace->id}&qtype={$qtype}");
}
$qform ->display();
但是cancel button
仍然提交表单。
您需要检查调用php文件中的表单是否已取消。例如:
$form = new quest_form();
if ($form->is_cancelled()) {
// Display a message or redirect somewhere.
redirect(new moodle_url('/foldername/cancelquesturl.php'));
} else if ($data = $form->get_data()) {
// Do something with the data.
}
