[英]passing arrays from the view to the controller cakephp
Here is a part of my view(a javascript method that is executed on a button click): 这是我的观点的一部分(单击按钮即可执行的javascript方法):
function assign()
{
var links_list1 = [];
var links1 = document.getElementById('moderatorUsers').getElementsByTagName('a');
for(var a in links1) {
if(typeof links1[a] == undefined) continue;
links_list1.push(links1[a].innerHTML);} var str1 =links_list1.toString();
var moderators = str1.split(',');
var links_list2 = [];
var links2 = document.getElementById('editorUsers').getElementsByTagName('a');
for(var a in links2) {
if(typeof links2[a] == undefined) continue;
links_list2.push(links2[a].innerHTML);} var str2 =links_list2.toString();
var editors = str2.split(',');
var links_list3 = [];
var links3 = document.getElementById('jEditorUsers').getElementsByTagName('a');
for(var a in links3) {
if(typeof links3[a] == undefined) continue;
links_list3.push(links3[a].innerHTML);} var str3 =links_list3.toString();
var jEditors = str3.split(',');
}
Here is the controller method i need to call using the 3 arrays from the javascript(moderators, editors,jEditors): 这是我需要使用javascript中的3个数组(控制器,编辑器,jEditors)调用的控制器方法:
function insertPos($moderators,$editors,$jEditors){
$account = new Account();
$account->insertPos($moderators,$editors,$jEditors);
}
I need to know how to execute the controller method insertPos($moderators,$editors,$jEditors) using the 3 arrays in the javascript method... 我需要知道如何使用javascript方法中的3个数组执行控制器方法insertPos($ moderators,$ editors,$ jEditors)...
I used this to send the arrays in the javascript like you told me: 我用它像您告诉我的那样在javascript中发送数组:
$.post('http://localhost/cakephp/Accounts/insertPos', {
data: {
'moderators': moderators,
'editors': editors,
'jEditors': jEditors
}
});
and in the controller i try to access my arrays like this: 在控制器中,我尝试像这样访问我的数组:
public function insertPos() {
if (!empty($this->request->data)){
print_r($this->request->data);
$moderators = $this->request->data['moderators'];
$editors = $this->request->data['editors'];
$jEditors = $this->request->data['jEditors'];
$account = new Account();
$account->assignPos($moderators,$editors,$jEditors);
}
}
the part inside the if(!empty($this->request->data))
is never executed so that means the arrays have not been sent to the controller.... where is the problem? if(!empty($this->request->data))
内部的部分永远不会执行,这意味着尚未将数组发送到控制器。...问题出在哪里?
thank you.... 谢谢....
It looks like you're trying to access a controller class directly. 看来您正在尝试直接访问控制器类。 This is not how CakePHP works. 这不是CakePHP的工作方式。 You have to go through the dispatch process. 您必须完成调度过程。 Please read: http://book.cakephp.org/2.0/en/getting-started/a-typical-cakephp-request.html 请阅读: http : //book.cakephp.org/2.0/en/getting-started/a-typical-cakephp-request.html
That said, the way you would POST to a CakePHP url is thusly: 也就是说,发布到CakePHP网址的方式是这样的:
// POST to the AccountsController's insertPos method
$.post('/accounts/insertPos');
To pass data, pass it in the data
option as specified with jQuery, prefixed with 'data', like data[moderators]
so it ends up in Cake's data variable. 要传递数据,请将其传递到jQuery指定的data
选项中,并以'data'开头,例如data[moderators]
这样它就以Cake的data变量结尾。
$.post('/accounts/insertPos', {
data: {
'data[moderators]': moderators,
'data[editors]': editors,
'data[jEditors]': jEditors
}
});
The data will now end up in $this->request->data
in Cake. 数据现在将以Cake中的$this->request->data
结尾。
Looking at your insertPost()
method, though, you are passing them simply as parameters, so instead you would write your ajax like so 但是,看着您的insertPost()
方法,您只是将它们作为参数传递,因此您应该像这样编写ajax
// POST is unnecessary here, since you aren't POSTing data
$.get('/accounts/insertPos/'+moderators+'/'+editors+'/'+jEditors);
You will probably need to stringify
your JavaScript arrays and use json_decode
in your inserPos
method to convert them to PHP objects, since you can't just pass arrays from JavaScript to PHP. 您可能需要对JavaScript数组进行stringify
处理,并在inserPos
方法中使用json_decode
将其转换为PHP对象,因为您不能仅将数组从JavaScript传递给PHP。
don't use array notation in data parameter; 不要在data参数中使用数组符号; just use keys like this: 只需使用如下键:
$.post('/accounts/insertPos', {
data: {
'moderators': moderators,
'editors': editors,
'jEditors': jEditors
}
});
and in your controller access it as $this->request->data[key]
not $this->request->data->data[key]
并在您的控制器中将其作为$this->request->data[key]
访问,而不是$this->request->data->data[key]
in the view replace your assign function with the following: 在视图中,将您的assign函数替换为以下内容:
var moderators, editors, jEditors;
function assign()
{
var links_list1 = [];
var links1 = document.getElementById('moderatorUsers').getElementsByTagName('a');
for(var a in links1) {
if(typeof links1[a] == undefined) continue;
links_list1.push(links1[a].innerHTML);} var str1 =links_list1.toString();
moderators = str1.split(',');
var links_list2 = [];
var links2 = document.getElementById('editorUsers').getElementsByTagName('a');
for(var a in links2) {
if(typeof links2[a] == undefined) continue;
links_list2.push(links2[a].innerHTML);} var str2 =links_list2.toString();
editors = str2.split(',');
var links_list3 = [];
var links3 = document.getElementById('jEditorUsers').getElementsByTagName('a');
for(var a in links3) {
if(typeof links3[a] == undefined) continue;
links_list3.push(links3[a].innerHTML);} var str3 =links_list3.toString();
jEditors = str3.split(',');
}
Good luck 祝好运
