I'm trying to get pagination working in my joompla component admin page (table of records from database).
I'm using the standard method found on the net, so in my view class I have:
function display($tmpl=NULL)
{
$this->tabela = $this->get('Items');
$this->pagination = $this->get('Pagination');
$this->state = $this->get('State');
...
and then in my default template for this view:
<tfoot>
<tr>
<td colspan="7" >
<?php echo $this->pagination->getListFooter(); ?>
</td>
</tr>
but the pagination is not showing up. In the place where it should occur I can only see this (in website's HTML):
<div class="pagination pagination-toolbar">
<input type="hidden" name="limitstart" value="0">
</div>
How can I get this pagination work?

I've finally made my app in angular 2. Everything is solved, except one thing. When I add item into my table or edited it, I can't see the change until I refresh page or click for example next page button (I have implemented pagination). I included:
<script src="node_modules/systemjs/dist/system-polyfills.js"></script>
<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
in this order. My method for adding item is very simple:
addDepartment(item){
this._departmentService.addDepartment(item)
.subscribe(departments => this.department = departments.json());
this.getAll();}
Whhen I add item, and put breakpoint on get method, It is called correctly and I get right information from my DB, but I don't know why view isn't refreshed then. Do you have any idea why is it happened? Thanks for suggestions!
EDIT: department is just department: Department, where Department is interface with properties (departmentNo, departmentName, departmentLocation). The view for adding item looks like:
<form [ngFormModel]="myForm"
(ngSubmit)="addDepartment(newItem); showAddView=false" [hidden]="!showAddView" align="center">
<div>
<label for="editAbrv">Department name:</label><br>
<input type="text" [(ngModel)]="newItem.departmentName" [ngFormControl]="myForm.controls['departmentName']" >
<div *ngIf="myForm.controls['departmentName'].hasError('required')" class="ui error message"><b style="color:red;">Name is required</b></div>
</div>
<br/>
<div>
<label for="editAbrv">Department Location:</label><br>
<input type="text" [(ngModel)]="newItem.departmentLocation" [ngFormControl]="myForm.controls['departmentLocation']" >
<div *ngIf="myForm.controls['departmentLocation'].hasError('required')" class="ui error message"><b style="color:red;">Location is required</b></div>
</div>
<br/>
<div>
<button type="submit" [disabled]="!myForm.valid" class="ui button">Add item</button>
<button><a href="javascript:void(0);" (click)="showHide($event)" >
Cancel
</a></button>
</div>
</form>
and my department table is:
<table align="center">
<thead>
<tr>
<td>#</td>
<td><strong>Department</strong></td>
<td><strong>Department Location</strong></td>
<td><strong>Edit</strong></td>
<td><strong>Delete</strong></td>
</tr>
</thead>
<tbody>
<tr *ngFor="#department of departments | searchString:filter.value ; #i = index">
<td>{{i + 1}}.</td>
<td> {{department.departmentName}}</td>
<td>{{department.departmentLocation}}</td>
<td>
<button class="btnEdit" (click)="showEdit(department)">Edit</button>
</td>
<td>
<button class="btnDelete" (click)="deleteDepartment(department)" >Delete</button>
</td>
</tr>
</tbody>
</table>
With this code, you don't wait for the response of the addDepartment request and execute the getAll request directly.
addDepartment(item){
this._departmentService.addDepartment(item)
.subscribe(departments => this.department = departments.json());
this.getAll();
}
You should move the call to getAll within the callback registered in subscribe. At this moment, the addDepartment is actually done and you can reload the list...
The code could be refactored like this (it's a guess since I haven't the content of addDepartment and getAll methods):
addDepartment(item){
this._departmentService.addDepartment(item)
.subscribe(addedDepartment => {
this.department = this.getAll();
});
}
This issue occurs because of the way you're using departmant and how change detection works. When you use *ngFor="#department of departments", angular change detection looks for a object reference on departments array. When you update/change one of the items in this array object reference to the array itself doesn't change, so angular doesn't run change detection.
You have few options:
1) change reference of the array by replacing it with new array with updated values
2) tell angular explicitly to run change detection (which I think is easier in your case):
constructor(private _cdRef: ChangeDetectorRef) {...}
addDepartment(item){
this._departmentService.addDepartment(item)
.subscribe(departments => this.department = departments.json());
this.getAll();
this._cdRef.markForCheck();
}
I previously had a custom form that users could fill out to place work orders, and once they hit submit, it would create a new ticket with all the information and add it to one of the RT queues.
We previously used Mason to do this, but now we've moved to WordPress and would like to redo this in a cleaner way using PHP.
I read through the API documentation and reviewed this thread along with many others posted on Stack Overflow. I know how to connect to RT and create new tickets via command line and cURL, but I can't seem to figure out how to do so using the web interface on submit. I would really appreciate if someone could give me some pointers on where to start.
Thanks
Edit:
Thank you for the response. Below is the form I've made which interacts with a our SQL database to pull some information and I need it to create a new ticket with all the information on submit. Should I create a new php file similar to [this][2] and include it as a form action?

Edit 2:
Thanks. Using the documentation and code from this repo I created a new file called new_ticket.php with the following content:
<?php
if($_POST['action'] == 'call_this') {
require_once 'RequestTracker.php';
$url = "www.test.com/rt/REST/1.0/";
$user = "user";
$pass = "password";
$rt = new RequestTracker($url, $user, $pass);
$content = array(
'Queue'=>'9',
'Requestor'=>'test#example.com',
'Subject'=>'Lorem Ipsum',
'Text'=>'dolor sit amet'
);
$response = $rt->createTicket($content);
print_r($response);
}
?>
I also made of copy of RequestTracker.php from the same Github repo.
In the file where the form is located, I added the following script and added create_ticket() as an action to the onclick property of submit button. But this doesn't seem to be working. I tried logging something to the console to see how far the code gets, the create_ticket() function is being called properly but anything that comes after $.ajax({ ... above will not appear to the console. I also tried putting some console logs in my new_ticket.php file but that doesn't log anything either, so what am I doing wrong?
<script>
function create_ticket() {
$.ajax({
url:"new_ticket.php", //the page containing php script
type: "POST", //request type
data:{action:'call_this'},
success:function(result){
alert(result);
}
});
}
</script>
PS: I'm using ajax because I need to run the PHP code onclick and this can't be done directly as it would in Javascript.
Probably the easiest approach is to look at the PHP examples in the REST documentation on the Request Tracker wiki. You don't mention the version of RT you are using, but the REST interface has been stable so this should work with most versions.
I'm looking to create a log in feature every time users go to various members only pages, which returns them to the original page after logging in. I've seen various answers to this question but none of them seem to include a check feature followed by a return to the original page. At the moment the code I have created doesn't seem to recognize that I have logged in and keeps returning me to the log in form. Any answers will be greatly appreciated. I realize I am using deprecated code but that is the only version my host provider's servers recognize.
Here's the code I am putting at the top of each members page
<?php
session_start();
if($_SESSION['login'] != "yes" )
{
header("Location: main_login.php");
exit();
}
?>
This then opens the main_login.php page
<table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form name="form1" method="post" action="checklogin.php">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td colspan="3"><strong>Member Login </strong></td>
</tr>
<tr>
<td width="78">Username</td>
<td width="6">:</td>
<td width="294"><input name="myusername" type="text" id="myusername"></td>
</tr>
<tr>
<td>Password</td>
<td>:</td>
<td><input name="mypassword" type="password" id="mypassword"></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td><input type="submit" name="Submit" value="Login"></td>
</tr>
</table>
</td>
</form>
</tr>
</table>
On clicking the login button the following code in checklogin.php checks the entries
<?php
$host='.....'; // Host name
$username='.....'; // Mysql username
$password='........'; // Mysql password
$db_name='....'; // Database name
$tbl_name='......'; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_start();
$_SESSION['myusername'];
$_SESSION['mypassword'];
header("location:entry_form_european_languages.php");
}
else {
echo "Wrong Username or Password";
}
?>
The last header location refers to the page I would like to return to, which seems to the repeat the process of opening up the login and check in files- as if to indicate that the return page doesn't recognize that the log in was successful.
I would need to add something that was relative to each page, but since I don't know where I am going wrong with the fixed page return, I can't move on to that stage of coding.
I did have an alternative header address which took it to the following page login_success.php which gave the impression that username entries had been accepted, but this doesn't allow me to return to the original page
<?php
session_start();
if(isset($_SESSION[$myusername])){
header("Location:entry_form_european_languages.php");
}
?>
<?php
include '........';//Formatting for the page
?>
<html>
<body>
Login Successful
</body>
</html>
Thanks in advance.
There are a few extra things I needed to add to make the session details work, as follows. This code needs to go ahead of any other code on the page including any html code that relates to character formatting. Although I have coded it out the error reporting line is handy for indicating which line is not being read by the php server, should you have continued problems.
<?php
//error_reporting(E_ALL); ini_set('display_errors', 'On');
session_start();
ob_start();
if(!isset($_SESSION['myusername'])){
header('Location:main_login.php');
}
else if (isset($_SESSION['myusername'])){
}
$myusername=$_SESSION['myusername'];
$Page_Title ='Members Profile';
?>
I've input:
<g:form role="search" class="navbar-form-custom" method="post"
controller="simple" action="addEntry">
<div class="form-group">
<input type="text" placeholder="Put your data HERE"
class="form-control" name="InputData" id="top-search">
</div>
</g:form>
And table:
<table class="table table-striped table-bordered table-hover " id="editable">
<thead>
<tr>
<th>Name</th>
<th>Created</th>
</tr>
</thead>
<tbody>
<g:render template="/shared/entry" var="entry"
collection="${entries}" />
</tbody>
</table>
Controller:
#Secured(['ROLE_USER', 'ROLE_ADMIN'])
class SimpleController {
def springSecurityService
def user
def index() {
user = springSecurityService.principal.username
def entries = Entry.findAllByCreatedBy(user)
[entries: entries]
}
def addEntry(){
def entries = Entry.findAllByCreatedBy(user)
render(entries: entries)
}
}
I just want to dynamically update the table with data from input string.
What is the best way?
Will be grateful for examples/solutions
You can update the table using AJAX with Grail's formRemote tag.
Input form
<g:formRemote
name="entryForm"
url="[controller: 'entry', action: 'add']"
update="entry">
<input type="text" name="name" placeholder="Your name" />
<input type="submit" value="Add" />
</g:formRemote>
HTML table
<table>
<thead>
<tr>
<th>Name</th>
<th>Created</th>
</tr>
</thead>
<tbody id="entry">
<g:render
template="/entry/entry"
var="entry"
collection="${entries}" />
</tbody>
</table>
Entry template
<tr>
<td>${entry.name}</td>
<td>${entry.dateCreated}</td>
</tr>
Controller
import org.springframework.transaction.annotation.Transactional
class EntryController {
def index() {
[entries: Entry.list(readOnly: true)]
}
#Transactional
def add(String name) {
def entry = new Entry(name: name).save()
render(template: '/entry/entry', collection: Entry.list(), var: 'entry')
}
}
How it works
When the add button is pressed the add controller method is called. The controller method creates the domain instance and renders the _entry.gsp template. But instead of refreshing the browser page, the template is rendered to an AJAX response. On the client side, the rendered template is inserted into the DOM inside of the tbody element with id entry, as defined in the formRemote tag by the update attribute.
Note that with this approach all of the entries are re-rendered, not just the new one. Rendering only the new one is a bit trickier.

Grails AJAX
Just to give you direction ( you are not showing any of your controller and js code.):
Create an action your controller ( the responsible controller) that will render the template /shared/entry by passing entries collection.
On submit of the form make ajax call to the action defined above, then replace the tbody html by the returned view fragment(template).
I have got webapp in spring 3 mvc. The case is that I have index page with url, when user click on them should be display another page with details of choosed information. Now the details page is shown but without any information (on index page is creating model with correct variable but not in details controller - in debug mode).
index controller method:
#RequestMapping(value="/{site}", method = RequestMethod.GET)
public String showDetails(#RequestParam(value = "site", required = true) String site, Model model){
Catalog product = catalogEndpoint.getByTitle(site);
model.addAttribute("product", product);
return "details";
}
index html:
<form action="#" th:object="${product}" method="post" th:action="#{/details}">
<table border="0" width="600" th:each="sb, poz : ${product}" >
<tr >
<td rowspan="3" width="20"><span th:text="${poz.count}"></span></td>
<td>
<a th:href="#{/details/(site=${sb.tytul})}" th:value="${site}"><span th:text="${sb.tytul}"></span></a>
</td>
</tr>
<tr >
<td><span th:text="${sb.adres}"></span></td>
</tr>
<tr>
<td>category:<b><span th:text="${sb.category.name}"></span></b></td>
</tr>
</table>
</form>
details controller method:
#RequestMapping(value = "details/{site}", method = RequestMethod.GET)
public String showHomePage(#PathVariable(value = "site") String site, Model model){
model.addAttribute("product");
return "details";
}
details html:
<form th:object="${product}" method="get" th:action="#{/details}">
<table border="1" width="600" >
<tr >
<td ><span th:text="${tytul}"></span></td>
<td>
<span th:text="${opis}"></span>
</td>
<td><span th:text="${adres}"></span></td>
</tr>
</table>
</form>
I don't have any ideas how to map the details site (I tried a lot of solution but nothing). Thanks for help.
With thymeleaf, using th:object, you need to reference the fields of that object with *{}
<form th:object="${product}" method="get" th:action="#{/details}">
<table border="1" width="600" >
<tr >
<td ><span th:text="*{tytul}"></span></td>
<td>
<span th:text="*{opis}"></span>
</td>
<td><span th:text="*{adres}"></span></td>
</tr>
</table>
</form>
assuming tytul, opis, and adres are fields of product. Unless it's a type, don't forget
Catalog product = catalogEndpoint.getByTitle(site);
model.addAttribute("product", product);
in your details controller method, otherwise you won't have a Catalog model attribute.
inside your details controller where are you setting product object in your model ?
model.addAttribute("product");
is just settingstring object "product", fetch the product object and set it in details controller like you have done in showDetails method
Change
model.addAttribute("product");
To
Catalog product = catalogEndpoint.getByTitle(site);
model.addAttribute("product", product);
in "showPage" method.
