I am new to codeIgniter and Linux as well. When I tried to run http://localhost/CodeIgniter/hello/first_page it shows 404 Error: Page not found. My Controller class :
/*hello.php*/
class Hello extends CI_Controller
{
function __construct() {
parent::__construct();
}
function first_page()
{
$this->load->view('first_view');
}
}
And my first_view.php is :
<html>
<head>
<title>First CI Page</title>
</head>

NB: http://localhost/CodeIgniter shows the welcome message.And all files are executable(777)
Try this url.. You'll get it
http://localhost/CodeIgniter/index.php/hello/first_page
You have to include index.php

I am following https://help.twitter.com/en/using-twitter/embed-twitter-feed for embedding timeline in the angular page. Only button renders but not the actual timeline.
The index.html looks like:
<body style="margin:0">
<script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
<app-root></app-root>
</body>
app.component.html looks like below:
<a class="twitter-timeline"
href="https://twitter.com/TwitterDev/lists/national-parks?ref_src=twsrc%5Etfw">
A Twitter List by TwitterDev
</a>
Also tried things like app.component.ts:
ngOnInit(){
if ((<any>window).twttr.ready())
(<any>window).twttr.widgets.load();
}
But no luck
you need to load widgets.js script after twitter-timeline element is been render so if you place the script in index.html it is will load and the element hasn't render yet.
🌟 the best way around it is to create a script tag dynamically after the element is rendered.
twitter component
export class TwitterComponent {
#Input() user:string;
constructor(private renderer2: Renderer2,private el: ElementRef) {}
ngAfterViewInit() {
let scriptEl = document.createElement('script');
scriptEl.src = "https://platform.twitter.com/widgets.js"
this.renderer2.appendChild(this.el.nativeElement, scriptEl);
}
}
template
<a class="twitter-timeline" href="https://twitter.com/{{user}}">Tweets by {{user}}</a>
app componenet template
<app-twitter [user]="name"></app-twitter>
angular twitter widgets ⚡⚡
ngAfterViewInit() a lifecycle hook that is called after Angular has fully initialized a component's view.
Updated 🔥🔥
a simple soulution mention in this answer before by user named Bernardo Baumblatt
put the script link in the index.html
<script async src="https://platform.twitter.com/widgets.js" charset="utf-8">
</script>
load the twitter widgets when ngAfterViewInit method call
ngAfterViewInit() {
// #ts-ignore
twttr.widgets.load();
}
in any case the script has not loaded yet you will got an error like 🆘 twttr is not defined 👉 so download the widgets.js script and include it to your project by using import
main.ts
import './app/widgets.js'

I had a requirement of dynamically rendering timelines based on different twitter timelines.
I found a workaround by creating a variable in the constructor that stores the href based on the twitter username .
So for example if your link is "https://twitter.com/TwitterDev/lists/national-parks?ref_src=twsrc%5Etfw"
, you just put this in the constructor in a previously defined global variable , say "embedLink"
such as in your ts component:
#Component({
selector: 'app-tree-dashboard',
templateUrl: './tree-dashboard.component.html',
styleUrls: ['./tree-dashboard.component.css']
})
export class TreeDashboardComponent implements OnInit,AfterViewInit {
embedLink='';
constructor(private matIconRegistry: MatIconRegistry,
) {
this.embedLink= "https://twitter.com/TwitterDev/lists/national-parksref_src=twsrc%5Etfw"
}};
and then in your HTML :
<a class="twitter-timeline" href={{embedLink}}></a>
And lastly you only need to add the script in index.html which you have done already.
So you're good to go!
Below is my code. I'm creating blank website so I think it's should not be a problem. What I think is maybe the order of the script in index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Twitter</title>
<base href="/" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="icon" type="image/x-icon" href="favicon.ico" />
</head>
<body>
<app-root></app-root>
</body>
<script
async
src="https://platform.twitter.com/widgets.js"
charset="utf-8"
></script>
</html>
In my app.component.html
<a class="twitter-timeline"
href="https://twitter.com/TwitterDev/lists/national-parks?ref_src=twsrc%5Etfw">
A Twitter List by TwitterDev
</a>

I use hbs to render my pages with partials for navigation and footers.
router.get('/test', function (req, res) {
return res.render('test');
});
On one page I have template that uses mustache.js. This template doesn't work as it should as the {{}} seems to be picked up on the hbs render. Below is a basic example that illustrates the error. If I load this as a static page with express I get "Joe is a Web Developer", if I render it with hbs I get "is a".
Are there any work arounds that wont involve me changing how all my pages are rendered?
<!doctype html>
<html lang="en">
<head>
<title>Mustache.js Inline Method</title>
<script type="text/javascript" src="js/libs/mustache.js" ></script>
<script>
var view = {
name : "Joe",
occupation : "Web Developer"
};
function loadtemp(){
var output = Mustache.render("{{name}} is a {{occupation}}", view);
document.getElementById('person').innerHTML = output;
}
</script>
</head>
<body onload="loadtemp()" >
<p id="person"></p>
</body>
</html>
It was simple enough. I just had to escape the brackets with a \
So all it took was
\{{name}}
I'm new on Thymeleaf template engine, and I'm making an application with Spring Boot and Spring MVC. I'm working just with application.properties for the configuration.
I want to know how I can write only ONE layout but the contents in many files: for example content1.html, content2.html, etc. and use the layout that already have the header, the footer.
If it is possible, how can I send from the controller the content file that will be replaced in the layout?
You could do something like this. Let's say you create a page where all other content will be embedded - main.html. It will look something like this:
<!doctype html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3" xmlns="http://www.w3.org/1999/xhtml">
<div th:fragment="mainPage(page, fragment)">
<h4>Some header</h4>
<div th:include="${page} :: ${fragment}"></div>
<h4>Some footer</h4>
</div>
</html>
Then you want to create some page which will be embedded in your main.html page - some-page.html:
<!doctype html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3" xmlns="http://www.w3.org/1999/xhtml">
<div th:fragment="somePage">
<h1>${title}</h1>
</div>
</html>
The goal is to replace <div th:include="${page} :: ${fragment}"></div> within main.html with the content from some-page.html. In controller, that will look like this:
#Controller
public class DemoController {
#RequestMapping
public String somePage(Model model) {
// Note that you can easy pass parameters to your "somePage" fragment
model.addAttribute("title", "Woa this works!");
return "main :: mainPage(page='some-page', fragment='somePage')";
}
}
And there you go! Every time when you want to swap content in main.html, you just change page and fragment parameters within string in your controller.
I'm trying to run Twig (standalone, without Symfony 2) in a PHP project (Wamp) but it doesn't work : Twig shows the templates source code but does not execute the HTML. I don't find why. Here is my code :
index.php:
// DOCUMENT_ROOT (constant defined in a previous included file) : C:/Program Files/wamp/www/project
$sTwigPath = DOCUMENT_ROOT."/vendors/twig/lib/Twig/Autoloader.php";
if (file_exists($sTwigPath)) {
require($sTwigPath);
Twig_Autoloader::register();
$loader = new Twig_Loader_Filesystem(DOCUMENT_ROOT."/templates");
$tpl = new Twig_Environment($loader, array("cache"=>false));
try {
$oTemplate = $tpl->loadTemplate("home.html");
} catch (Twig_Error_Loader $e) {
error_log("Twig library not found", 0);
exit;
}
$aRender = array();
$aRender["myVar"] = "Wouah! myVar is displayed here!";
echo $oTemplate->render($aRender);
home.html :
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Home</title>
</head>
<body>
<h1>Home</h1>
{{myVar}}
</body>
</html>
I've no error (checked in PHP and apache logs).
in for example magento they have php seperated from phtml.
I also do the same thing.
But I can't figure one thing out, and that is:
When I have this php script:
class aclass extends main{
public function redirect(){
require_once($this->frontend_folder . $this->admin_folder . "beheer/edit_account.phtml");
}
public function nav_menu(){
return "<nav>some nav menu things in here</nav>";
}
and the "view" phtml script:
<!doctype html>
<html>
<head>
</head>
<body>
<div id="wrap">
<?php
echo $this->nav_menu();
?>
</div>
</html>
"$this" doesn't work, but how can I get this working?
you need to instantiate the class in the view.
<!doctype html>
<html>
<head>
</head>
<body>
<div id="wrap">
<?php
$c = new aclass; // instantiate the class
echo $c->nav_menu(); // run the function from the class
$c = null; // null the variable, maybe help garbage collection...
?>
</div>
</html>
this is not an optimal way to use it, but I hope the idea is clear.
EDIT: This is a simple solution, depending on your archetecture, you can do many things. In simpliest form, you should consider instantiating your class at the top of the view, then you can reference it by the handle you assign it to throughout the view.
