我将图像上传到“images”目录，并将一些信息上传到codeigniter中的数据库。但是当我在完成表单后点击提交按钮时，它什么也没做。它只是刷新。如果有人可以请查看此代码，并告诉我为什么它不起作用。先感谢您。 这是我的控制器代码：
<?php public function create()
{
if (!isset($_POST['submit']))
{
$title['title'] = 'Add News';
$this->load->view('templates/navbar', $title);
$this->load->view('News/create');
}
else
{
// image1
$ImageName = $_FILES['image']['name'];
$imageSize= $_FILES['image']['size'];
$imageSource = $_FILES['image']['tmp_name'];
move_uploaded_file($_FILES['image']['tmp_name'], "images/$ImageName");
$this->create_thumb($ImageName);
$this->compress($ImageName, $imageSize, "images/$ImageName");
// image2
if ($this->input->post('image2')){
$ImageName2 = $_FILES['image2']['name'];
$imageSize2= $_FILES['image2']['size'];
$imageSource2 = $_FILES['image2']['tmp_name'];
$this->compress($ImageName2, $imageSize2, $imageSource2);
}
// image3
if ($this->input->post('image3')){
$ImageName3 = $_FILES['image3']['name'];
$imageSize3= $_FILES['image3']['size'];
$imageSource3 = $_FILES['image3']['tmp_name'];
$this->compress($ImageName3, $imageSize3, $imageSource3);
}
// image4
if ($this->input->post('image4')){
$ImageName4 = $_FILES['image4']['name'];
$imageSize4= $_FILES['image4']['size'];
$imageSource4 = $_FILES['image4']['tmp_name'];
$this->compress($ImageName4, $imageSize4, $imageSource4);
}
$this->news_model->set_news();
$this->load->view('News/success');
}
}
?>

答案 0 :(得分：0)
如果您要发布提交，则必须在视图文件中使用<input />代替<button />。
但如果发布了一些内容，还有更好的方法可以检查：
if (!isset($_POST['submit']))
{
// do something if NOT posted
}
else
{
// do something if posted
}
更改为：
if ($this->input->post())
{
// do something if posted
}
else
{
// do something if NOT!! posted
}
