我是新手CodeIgniter,我一直在尝试实现表单提交功能,但每当我按"提交"表单页面时,只需刷新并且数据库不会更新!似乎$this->form_validation->run()总是返回假,但我不知道为什么.
所述控制器的功能如下:
public function write_prof_review($prof_id)
{
$this->load->model('Queries');
// form stuff here
$this->load->helper('form');
$this->load->library('form_validation');
$data['prof_id'] = $prof_id;
if($this->form_validation->run() == FALSE){
$this->load->view('create_prof_review', $data);
}
else {
$this->Queries->submit_prof_review($prof_id, $this->USERID);
$this->load->view('form_submitted');
}
}
这里是功能submit_prof_review()的模型:
function submit_prof_review($prof_id, $user_id)
{
$data = array(
'course_code' => $this->input->post('course_code'),
'easiness' => $this->input->post('easiness'),
'helpfulness' => $this->input->post('helpfulness'),
'clarity' => $this->input->post('clarity'),
'comment' => $this->input->post('comment')
);
$average = round((($data['easiness'] + $data['helpfulness'] + $data['clarity'])/3),2);
date_default_timezone_set('Asia/Hong_Kong');
$date = date('m/d/Y h:i:s a', time());
$data['average'] = $average;
$data['date'] = …我设置了名为"drawEverything()"的函数来运行onload,但是该函数没有运行,我在Firebug中得到一个错误,说"drawEverything未定义"？事情是,我确实定义了它!
我搜索了这个问题,大部分时间都是由于某种语法错误,但我看了一遍,却找不到任何语法错误.
我的代码如下:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Test</title>
<link rel=stylesheet href="style.css" type="text/css">
</head>
<script type="text/javascript">
var new_x = 110;
var new_y = 150;
function drawEverything(){
var temp_x = new_x;
var temp_y = new_y;
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
for (int i = 0; i < 5; i++){
ctx.beginPath();
ctx.arc(temp_x,temp_y,20,0,2*Math.PI);
ctx.stroke();
if ((i < 3) || (i == 4)){
temp_x += 40;
}
else if (i == 3){
temp_y += 20;
temp_x -= …
