I have this problem to solve.
I gonna make an email campaign to my clients with some affiliate promotions.
The email will have some direct links to the promotions that goes through a php script in my site. (ex: http://mysite.com/promo.php?promoId=x)
In this script I will manage my database queries and cookie.
In cases that I detect through the cookie that this user has not made any click in the last x days I would like to present him with two html pages: my main website page and the external site referring to the promo.
How can I do this? I currently use header( "Location: $promo_url" ) to redirect to the promo url... but in same cases stated before I would need two urls to open.
Thanks in advance for all your answers

You can either use frames (ugh), an iframe within the main page to display the second page (somewhat less ugh), or use popup windows (truly ugh, and probably not possible due to everyone having popup blockers these days).
You could have the script output JavaScript with window.open instead.
<script type="text/javascript">
window.open("link1"); // open link1 in a separate window
window.location.href = "link2"; // point this window to link2
</script>
If you can, however, it would be much better to explicitly show the user a link to the second location somewhere on the page instead of forcefully opening another window / tab for them.
Show them your site, and in your site have a hidden a link tag, which will link to the affiliate site with the attribute _blank. Using jQuery, once the DOM is ready trigger a click event to the hidden link tag.
E.x.
HTML
<a id="affiliateLink" href="http://www.affiliatesite.com/asdad" target="_blank" style="display:none;">Visit Affiliate</a>
JavaScript
$(document).ready(function(){
$('#affiliateLink').trigger('click');
});
There's really no good way to do what you want without using iframes (ugh) or popups (double ugh). The other answers are how to use those techniques, but a possible 'better' solution would be to display a banner on your page when you detect the user hasn't been to your site in a while. The banner could say something along the lines of Click here for information about our awesome promotion, and it'd be easy to make it stand out. That way, you're not forcing popups (which no one will ever see), and while iframes aren't terrible from a user perspective, they don't really scream "modern web design".

What has been known for a while, is that a "fast navigation" works easily for http://example.com/#1 --> http://example.com/#2.
However, there is a new technique out there. It enables fast navigation between http://example.com/1 --> http://example.com/2.
EXAMPLE: http://rageslide.com/
As you can see in the example, the navigation between http://rageslide.com/1 and http://rageslide.com/2 etc. via swiping apparantly DOES NOT FORCE THE ENTIRE SITE TO RELOAD.
I'd like to do the same for my site, but I have no idea how to do this. All pages served by my site are dynamic (via PHP and MYSQL).
I have this idea:
Cache the generated output of a page (http://example.com/2) for 60 seconds.
When the user is on http://example.com/1 preload (http://example.com/2) via Javascript.
The user navigates from http://example.com/1 to http://example.com/2. Since the content is preloaded and cached, the content will be served to the user instantly.
Different idea:
Somehow, http://example.com/1 is being interpreted as http://example.com/content.php#1 through a .htaccess. But I have no idea if this is possible or not.
Will this work? Or what would be the best way to solve this problem?
No, the url you see there is not used to load another page. There are AJAX requests in the javascript code contained in the website, that load the new content to display and update the URL bar.
You can read more about it in this article and in the following questions asked in the past:
Modify the URL without reloading the page
Updating address bar with new URL without hash or reloading the page
i can think of two possible thing you can try out.
first is simply use iframes to load the next and previous page of each page, and when someone swipes to the next page load the next page to a new iframe or a div with ajax or any other html element for that matter.
the other is to use the rel attribute, here is an explanation about it.
hope this helps you out
you can get pretty close without scripting anything or degrading the site by letting the browser cache the expected navigation point resources
for caching images, put dummies at the end of the body
<img .... height="0" width="0">
and for pages
<link rel=”prefetch” href=”url” /> there is also a rel attribute for next and previous for slide viewer type pages
Note: the url can be a javascript resource
Note2: the transition may be slightly less clean than dynamically populating from javascript especially on larger complex pages, but will still work with noscript or javascript turned off, so maybe a good fallback
I'm trying to code a seo friendly ajax portfolio right now. My goal is to provide javascript effects to users and normal html to bots/users without js.
Files:
index.php (starting point of my program)
aboutme.php (contains html code for "about me")
contact.php (contains html code for "contact")
The idea:
User visits index.php and clicks on "About me" -> loading animation appears -> aboutme.php gets loaded with ajax -> history.pushstate rewrites the url to aboutme.php.
-> When the user shares the current website url on fb/twitter/g+ the bots will get the correct title, body etc., as it is the normal html page without any javascript.
But my problem is: If other users open that page, they see directly the content. But I want to show them a loading animation first until the data got loaded with ajax (similar as they click on a link).
How can I achieve such an approach? Thank you very much!
Best way to do this, create a javascript file. Write the link tag into "head" part. This will make the javascript file downloaded before content. Javascript shows the animation, but at the same time browser will be downloading the content already in the background. On "document ready" event, stop animation.
This will let bots to access the content directly. Because javascript won't work for them.
To make your ajax content crawlable see https://developers.google.com/webmasters/ajax-crawling/, Bing supports this as well. Or use the HTML5 pushState, see http://www.seomoz.org/blog/create-crawlable-link-friendly-ajax-websites-using-pushstate, https://github.com/blog/760-the-tree-slider etc.
I've always thought this is more effort than its worth(generally), but to answer your question:
index.php, aboutme.php, contect.php should deliver full html.
certain links should have js event handlers intercept the click, and instead of loading aboutme.php, they load aboutme-content-only.php in the background. then update the dom and push state etc...
this way the site can easily degrade for those users who are first time visitors, as well as those whose browsers dont support push state or javascript.
I think that it is not a problem at all, keep your href of links as usual, then using JavaScript or jQuery change the default behavior of clicking link to load the linked contents with ajax.
my question is about this website - http://www.bits-apogee.org/2011/
whenever you click on the link in the side navigation bar, the middle part of the website is dynamically loaded. Also, the url also changes, everything else remains unchanged. how is this done?
is this some query plugin?
I totally agree with #JMCCreative. It looks like it's an actual refresh. You should look at the following post on StackOverflow.
Modify the URL without reloading the page
The site is using Hashes (#) in the URL to denote the new content being loaded.
This is useful for people bookmarking dynamically loaded content (normally hashes load to specific areas on a page, named anchors or ID's for new browsers), because they don't trigger the page to refresh...
http://www.highrankings.com/urls-with-hashtags-307 there are drawback (SEO) concerns to this... however you will notice more and more sites doing it so i would assume the SEO robots will get better.
There are 2 possibilities:
You can use the HTML5 capabilities to change the url (history pushState), however this feature isn't available in all browsers yet. For more information, look at this SO post: Is there a way to change the browser's address bar without refreshing the page? .
You can use a hashtag (#) part as fall back for browsers who don't have above feature yet.
If you use jQuery, you can use the handy plug-in jQuery Address. This will take care of both above cases.
They're not using a plugin. They're doing an ajax request to a URL like this:
http://www.bits-apogee.org/2011/getcontent/?even=Rachel+Armstrong
and dumping the overview in the container.
The circle of this type of process is usually like this:
listen for link clicks
on click, prevent default on event.
user window.history.pushState to update url
some other code - hears new history
generates a url to get the content.
ajax load the url
dump the data into a container
2 Libraries I have used, both are easier than the above, as they rely on loading a regular html page via AJAX instead the example site you point to, which used a JSON format to get the data.
Pjax - update peices of the page, by pulling that HTML node from a different URL.
Ajaxify - easiest solution, you could do that effect on an HTML site in 10 minutes.
Basically I want to replicate the page changing effect found here, at http://timvandamme.com/
But instead of using #values I want to use PHP includes, mainly because I want the site to be as uber-seo-friendly as possible... but still have this nice effect.
So is there a way of doing this? I have a main index file which includes other php files in the centre using the usual 'GET' method, so my pages look like: "index.php?page=about"
In my jQuery code I want to have a declaration where if I click the navigation, the content scrolls up, then once the relevant PHP file has loaded, have the content scroll back down and show the new page content (whilst also of navigated to the new page in the address bar, so if the user clicks the back button in their browser, they return to the previous page).
I know how to code the scrolling bits, it's just literally the ajax loading includes / page navigation parts I'm struggling to work out :\
Any help would be MUCH appreciated! Thanks in advance.
Use standard links in your navigation. In your onClick function, use event.preventDefault() to prevent the pages from redirecting your actual users (but they still appear as normal links to search engines).
Foo
<script>$("a").click(function(event){
event.preventDefault();
navigate($(this).attr('href'));
});</script>
Use the onClick function of the links to change the page's content with AJAX (just like it appears on the site you linked), but additionally set up each "page" (using error documents, mod_rewrite or something) to display its content, but allow navigation in this same way. By doing so, you will have the same functionality with the search-friendliness you desire.
To add to the others, some search engines understand this problem and offer site map utilities. You can check out google's site map solutions here:
http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=156184
The site map will allow you to explicitly inform google about certain uri's (like http://timvandamme.com/#about).
We all have come across web pages which take some time to show the content the user is waiting for and in the mean time display ads on the page.
I'm not talking about the pages that show full-page ad with 'skip this ad' button.
A typical example of what I'm referring to is: I visit a free plugin site. Click on the plugin I want to download it opens a new page which has the link to the plugin zip file. But the link does not appear immediately. When the page is loaded it is full of ads with other misleading (:P) download links. The actual link I'm interested in appears after say some 5 seconds, squeezed between two ads.
How can this be done for a PHP based website? Will a simple sleep() or usleep() do?
No.
When you issue a sleep() or a usleep() in a server side language (PHP) the sleep occurs on the server side, typically before output is sent to the user.
You would need to implement the functionality you desire using Javascript and the setTimeout() function.
You can have the link in a div and hide it initially and start a Javascript timer to show it.
Something similar to what you are looking for.
Something is hidden
<div id="hid" style="visibility: hidden">TADA!</div>
here
<script type="text/javascript">
function showIt() {
document.getElementById("hid").style.visibility = "visible";
}
setTimeout("showIt()", 1000); // after 1 sec
</script>
Source
With a setTimeout() in javascript to make a <div> containing the link visible after some amount of time.
