I would like to include a CodeIgniter comment form in an existing php page. Currently I am including the comment form with
$_SERVER["REQUEST_URI"] = "comment/index2/".$page;
require_once($directoryLevelPrefix . "staff/codeigniter/index.php");
However, when codeigniter loads the view to display the results of the form I lose the content on my original php page which contained the form. I have tried adding a redirect after the form data is added to the database to redirect to my original php page e.g.
redirect($_POST['return'])
But I want to pass some variables, such as 'thank you for your comment', and this causes a headers already sent error.
Alternatives might be to use ajax, but I would like the whole page to refresh when the comment is submitted.
I had a similar need and I just loaded the CodeIgniter form in an iframe. This was to put a contact form on a WordPress page. I went with the iframe because my needs were limited to this one form and I felt it didn't require trying to integrate CodeIgniter and WordPress in any way.
One Pro of this method is that the form can be submitted and load a confirmation page, an error page, or even be a multi-page form and all that navigation takes place inside the iframe so you never leave the page that you are on while using the form. Another Pro is that the form is totally portable.
The Cons of course are anything you might not like about using iframes which could be many things based on your needs and preferences.
That is because CodeIgniter is a framework designed to handle displaying entire web pages. You can't just include it, as it tries to send new headers and everything.
Two solutions:
You may be able to load the codeigniter page as the main page, and just include your original php code like a view file. This depends on how your original php file is set up.
You could possibly use cURL to call the page from your own server, to get the html output as a string, then echo it to your current page. This isn't very efficient though.
As C. Scott Asbach mentioned, you could load the whole page in an iframe. Probably not a good idea though, as far as I'm aware iframes are deprecated and make for messy websites.
Probably best is to just try and avoid using CodeIgniter to display a subform in an existing page :-)

I'm taking an online course from a site that does not provide for asking questions about the content, so I am asking you.
This is one of the MUSTS for page titles:
"On a so-called single-page application — in which AJAX is used to bring in new content without refreshing or loading the entire web page — any time that the URL changes, the page title should be updated accordingly"
I always thought that if you used ajax to change part of a page the page itself would remain static. That is why would a URL change with an AJAX call. Are there any examples showing what this looks like?
AJAX requests don’t change the browser URL or history. To mimic the behaviour of traditional websites, single page apps will modify the URL and history and use the URL to change the view.
For more on changing the browser history, see Adding and modifying History entries.
Currently i have been using an iframe component to display a php page that i have written. the reason i used iframe rather than writing a joomla component in the first place was for 2 reasons, the information that is displayed in that page is from a remote mssql sever and the second was that i didnt really understand how to write one.
Now i have completed the creation of the php page that i display within the iframe, but now i need to be able to have it inherent within the joomla site, for both display reasons and security.
basically its a single page that displays information in a bunch of drop down boxes and then a submit button is clicked and it posts that information to another php page that again queries the mssql server and displays the results based on the post from the previous page.
query.php, posts some variables to results.php and is displayed in a table.
i have the functionality perfect, but i dont understand the documentation i have read so far. is there any simple component i can see the code of so that i can try and work out whats going on?
You might want to look at http://docs.joomla.org/J3.1:Developing_a_MVC_Component/Introduction and follow the process outlined.
My site is AJAX but it pulls content from .html files. Some of those files have been indexed without the #!, so they just function as a basic html site. I want to redirect users that land on the non ajax page to the #! version. I tried a redirect (without thinking about it) and it created an endless loop with the dynamic content.
If you look at the code, you will see that it uses js to place the static pages into a content wrapper.
I am equally having trouble with an seo issue, where google does not appear to be requesting the escaped_fragment version... that or I need some help. I thought that since it was pulling content from html files, I could just copy those pages and add name it _escaped_fragment_=page.html it is not working. I tried a redirect, but google fetch just showed the redirect request and not content.
It was a template that I purchased... I figured out how to modify the theme and content, but this is beyond me.

I decided to scrap the hashbang method. I have real pages, and I decided to let them be searched and indexed. I am waiting on a solution to pull only the body into the ajax content warapper; however, I was able to apply basic CSS to the pages without messing anything up when loaded into the main page via ajax.
I used
$("a").attr("href", function(i, href) (some js stuff to add a hash-- hostname +# href)
to add a hash to the clean urls that were internal from the main menu. This created a loop if added to the pages, so I used a clean url with an onclick redirect to the ajax version. "/" before the link.
onclick="window.location = '/#link.html';return false;"
I had a JS redirect that detected if there was a hash before the page link, and if not, added it; however, google did not like it! Sure the pages are not as nice. That said, I have content for non JS enabled browsers. As soon as I get the main.js modified so that it ignores head elements, I can dress them up even more. Each page has links that will get a user to the ajax version, including the home button "/#".
My website uses ajax.
I've got a user list page which list users in an ajax table (with paging and more information stuff...).
The url of this page is :
/user-list
User list is created by ajax. When the user click on one user, he is redirected to a page which url is : /member/memberName
So we can see here that ajax is used to generate content and not to manage navigation (with the # character).
I want to detect bot to index all pages.
So, in ajax I want to display an ajax table with paging and cool ajax effetcs (more info...) and when I detect a bot I want to display all users (without paging) with a link to the member page like this :
JohnBob...
Do you think I can be black listed with this technique ? If you think so, could you please provide an alternative solution by keeping these clean urls and without redeveloping the user-list (without ajax) ?
Google support a specification to make AJAX crawlable:
http://code.google.com/web/ajaxcrawling/docs/specification.html
I did an experiment and it works:
http://seo-website-designer.com/SEO-Ajax-Google-Solution
As this is a Google specification, you won't get penalised (unless you abuse it).
Saying that, only Google support it at the moment (AFAIK).
Also, I believe following the concept of Progressive Enhancement is a better approach. That is, create a working html website then make the JavaScript enhance it
Maybe use the urls with an onclick to trigger your AJAX scripting? Like
Some URL
I don't think Google would punish you for this, you primarily use JScript, but you do provide a fall back for their bot, so your site doesn't get any less accessible.
EDIT
Ok, I misunderstood. Then my guess would be you basically have two options:
1. Write a different part of your site where bots end up, or,
2. Rewrite your current site to for example always give a 'full' page, with an option to only get, say, the content div. Then you can get only the content with JavaScript, but bots will always get a nice page.
Hi Masters Of Web Development.
I have a not that simple question this time. I have got a simple external HTML page, that I want to include in my site. The HTML page contains a submit form or something like that, and I wish to send this data from the form, without to reload the whole page. So I decided to put HTML page inside iframe. But, some people said that this is older technology, google doesn't like iframes, etc. So I want to use something like AJAX or JQuery to load that external HTML page, and to send submit form without reloading the whole page with it. :)
Any suggestions on how to make this?
Thanks in advance :)
Do you really need Google to index that iframe form? If that's the only iframe you have throughout the site, it aint going to be a problem in terms of google indexing.
About using the Iframe, if you are not comfortable learning and building ajax-type form, you'll still be fine (like what Frankie commented). Just make sure the form works, usable and compatible with popular browsers.
You want to use the jQuery Forms Plugin. Its very straightforward and easy to turn any normal HTML form into an AJAX form.
