在使用Codeigniter之后,我仍然无法弄清楚这3个功能之间的区别.通过调用类自动调用所有函数？
class Upload extends Controller {
function Upload()
{
parent::Controller();
echo 'test';
}
function __construct()
{
parent::Controller();
echo 'test';
}
function index()
{
echo 'test';
}
}
为什么不重定向在这里工作.我正在调用未定义的函数redirect().
class Login extends CI_Controller {
function index() {
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
$this->load->view('login_view');
}
function authenticate() {
$this->load->model('user_model');
$query = $this->user_model->authenticate();
if($query) {
$data = array(
'username' => $this->input->post('username'),
'is_logged_in' => true
);
$this->session->set_userdata($data);
redirect('/site/news_feed');
}
else {
$this->index();
}
}
}
不知道发帖规则,但我会告诉你,出了大门,这是一个重复的问题这一个,但我问这是否是"最佳实践"的方式来做到这一点？
我正在尝试创建一个别名,它将获取所有"已修改"的文件,并对它们运行php语法检查...
function gitphpcheck () {
filearray=()
git diff --name-status | while read line; do
if [[ $line =~ ^M ]]
then
filename="`echo $line | awk '{ print $2 }'`"
echo "$filename" # correct output
filearray+=($filename)
fi
done
echo "--------------FILES"
echo ${filearray[@]}
# will do php check here, but echo of array is blank
}
是否有可用的Codeigniter库
Elliot Haughin的这个库应该包含登录部分,但我不太确定导入配置文件数据.
有人有这方面的信息吗？
好的,这是我的愚蠢问题.我在这里学习和...我一直在看这个,我不明白.我有一个数组,其中包含一些通过对象提供的值.像这样:
function blogObj(name,date,user_entry){
this.names = name;
this.dates = date;
this.blog_entry = user_entry;
this.propsComb = this.names + this.dates + this.blog_entry;
}
var blogRun = [
new blogObj("name ", "something ", "something "),
new blogObj("name ", "something ", "something "),
new blogObj("name ", "something ", "something "),
new blogObj("name ", "something ", "something "),
new blogObj("name ", "something ", "something "),
];
var i=0;
var mssgs = "";
现在当我用这个doc.write来测试这样的循环时:
function hmm(){
while(i < blogRun.length){
mssgs = blogRun[i].propsComb + '<br/>';
document.write(mssgs);
i++;
} …我有一个页面可以快速登录检查并访问一些Web服务以获取一些JSON数据.它返回的数据如下所示:
{ 'RESPONSE' : 'INVALID','CAMPAIGNID' : '0','MORELINK' : '' }
我用来获取这些数据并尝试根据信息弹出模态窗口的代码是:
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "Login.asmx/Logon",
data: strData,
dataType: "json",
success: function (response) {
$('#divResp').html(response.d);
$(response.d).each(function(index,item){
alert(item.campaignid);
});
if (res.indexOf('invalid') >= 0){
//invalid account information UNP
foo = "You entered an invalid account number or password";
showDialog('screenActivate.asp',test_imgName);
}
if (res.indexOf('none') >=0) {
//do not deliver splash screen
foo = "No splash screen for YOU!";
}
if (res.indexOf('error') >=0) {
//general error
foo = "You entered an error"; …我想要一些关于如何使用JQuery在文档正文中插入新元素的人的帮助.
我恢复了身体:
var a = $(editorFrame).contents().find('body').html();
然后,我需要验证身体是否有元素<p></p>,不管它,我必须在第一个之后放置这个元素<DIV>.这是我的身体
<body>
<div id="testeFooter" class="footer-element">
<table id="footerDiv" class="mceItemTable" width="100%">
<tbody>
<tr>
<td id="footerContent">
<b>Digite aqui o seu Rodapé</b>
</td>
</tr>
</tbody>
</table>
</div>
<div id="testeHeader" class="header-element">
<table id="headerDiv" class="mceItemTable" width="100%">
<tbody>
<tr>
<td id="headerContent">
<b>Digite aqui o seu cabeçalho</b>
</td>
</tr>
</tbody>
</table>
</div>
<p>ESSSE MODELO TESTE</p>
</body>
我只需要知道如何在第一个身体之后放置一个新元素.
谢谢你们可以帮助我!
来自更高级别的语言,我试图通过学习c来改变自己.我正在尝试理解指针和内存分配(我之前从未考虑过的事情).
我正在尝试的代码
#include <stdio.h>
int main()
{
int array[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52 };
printf("\nShuffling...\n\n");
shuffle(array, sizeof(array)/sizeof(int));
int i;
for(i = 0; i < sizeof(array)/sizeof(int); i++)
{
printf("%d\n", array[i]);
} …这是我正在尝试运行的功能......
(defn mongean [cards times]
(let [_cards (transient cards)]
(loop [i 0 c (get cards i) _count (count cards) _current (/ _count 2)]
(assoc! _cards _current c)
(if ((rem i 2) = 0)
(def _newcur (- _current (inc i)))
(def _newcur (+ _current (inc i))))
(if (<= i _count)
(recur (inc i) (get cards i) _count _newcur )))
(persistent! _cards)))
这导致了这个例外......
Exception in thread "main" java.lang.ClassCastException: clojure.lang.PersistentHashSet$TransientHashSet cannot be cast to clojure.lang.ITransientAssociative
作为对clojure的新手,我也很感激对我上述方法的任何建设性批评.目标是获取List,并返回重新排序的列表.
