我正在創建一個網站,用戶可以在那裏上傳自己的背景圖片,上傳後他們看到他們上傳的每個背景都是由一個數字表示的菜單,點擊數字將會在理論上加載到新的背景中,但是我注意到這是否也再次調用視圖(視圖已經從另一個函數加載,有沒有一種方法可以將數據傳遞到視圖而不加載視圖,我可以用ajax來做到嗎?如果是這樣的話?如何動態背景圖片建議
我的代碼目前
public function set_background() {
$this->load->model('image_model');
if($query = $this->image_model->get_background_by_id($this->uri->segments[3])) {
if($query) {
$data['new_background'] = $query;
}
}
$this->load->view('template/background-select', $data);
}
我的模型:
public function get_background_by_id($background_id) {
$this->db->select('background_name');
$this->db->from('background');
$this->db->where('background_id', $background_id);
$query = $this->db->get();
return $query->result_array();
}
我查看
<div id="background-select">
<?php
$count = 0;
if(isset($special)) {
foreach ($special as $row) {
$count ++;
print '<div class="select">';
print "<a class='background_btn' href='index.php/home/set_background/".$row['background_id']."'>$count</a>";
print '</div>';
if($count == 1) {
$background = $row['background_name'];
}
}
}
if(isset($generic)) {
foreach ($generic as $row) {
$count ++;
print '<div class="select">';
print "<a class='background_btn' href='index.php/home/set_background/".$row['background_id']."'>$count</a>";
print '</div>';
if($count == 1) {
$background = $row['background_name'];
}
}
}
if(isset($user_background)) {
foreach ($user_background as $row) {
$count ++;
print '<div class="select">';
print "<a class='background_btn' href='index.php/home/set_background/".$row['background_id']."'>$count</a>";
print '</div>';
if($count == 1) {
$background = $row['background_name'];
}
}
}
?>
</div>
<div id="wrapper" style=<?php echo"background:url(/media/uploads/backgrounds/".$background.");";?>>
視圖獲取原本這裏裝
public function index() {
// $this->output->enable_profiler(TRUE);
$data = array();
if($query = $this->category_model->get_all_online()) {
$data['main_menu'] = $query;
}
$this->load->model('image_model');
/*
* Sort out the users backgrounds, basically do a check to see if there is a 'special' background
* if there is not a 'special' background then IF the user is logged in and has a background of there
* own show that one, if not show a generic one, if they are not logged in show a bang one
*/
$image = array();
if ($query = $this->image_model->get_special_backgrounds()) {
$image['special'] = $query;
} elseif(!isset($image['special']) && !isset($this->session->userdata['user_id'])) {
if($query = $this->image_model->get_bang_background()) {
$image['generic'] = $query;
}
}
if(isset($this->session->userdata['user_id'])) {
if($query = $this->image_model->get_user_backgrounds($this->session->userdata['user_id'])) {
$image['user_background'] = $query;
}
}
$data = array_merge($data, $image);
$this->load->view('home/main_page.php', array_merge($data, $image));
}
希望一些可以幫助感謝
看起來是一個很大的幫助,只是不能讓我的頭繞着邏輯,謝謝 – Udders 2010-01-08 10:45:53
後續評論道歉,但我很好奇,你是否得到它現在爲你工作? :) – pinkgothic 2010-01-29 09:55:11
