I have a website layout divided into the multiple partial files. One of them is a view which seats in the sidebar. There is a link in it (Facebook Connect), when I press it, it call a specific function, when it's completed without any errors, i received a blank page.
How to program it, so after processing a function inside another Controller, it will stay at the same url ?
Here is a visual. Imagine that I'am on this url http://localhost/web/blog. Here, on that page, i have a sidebar loaded with a link in it, which once it's pressed it will process a function. The url of this link in the sidebar is http://localhost/web/member/facebook_login.
After it's done, it should stay on the same url http://localhost/web/blog instead of /web/member/facebook_login.
Is it possible to do it without using a redirect() function ? So it will stay on the same page whenever you are, if your url is /web/home or web/about-us etc. ?
Thanks in advance guys
Why using the HTTP referrer is a bad idea, i just explained in my comment.
The url of this link in the sidebar is http://localhost/web/member/facebook_login
Then you should put the URL of the current page into that link, as a parameter:
http://localhost/web/member/facebook_login?go_back_url={url_of_the_current_page}
Then, after successful login, you can use the value of the parameter go_back_url to redirect back to the address it contains.
Found it!
Instead of using redirect('somecontroller/somefunction/someslug') you can use user_agent library.
redirect($this->agent->referrer());
Along by loading the user_agent library to make it possible $this->load->library('user_agent');

Here is the problem, I have a WP site that changes the display depending on the presence or not of a parameter in the URL.
If no parameter the whole post shows normally.
If the user has the parameter in the URL the post will be split into many sections (break lines are used as separators) and each time he clicks next the page will load and the URL will change to "/2" for the second element of the post for example. This is what I have for the moment and it works.
With parameter in the URL I want the users to have a slide that only loads the content without the page loading but I can't find a way to do this in WP.
Is it possible with jQuery? For example, load all the content first and show the appropriate section after each click? How would you go about it?
I'm not asking for a code but the logic that you'll use to tackle this issue if you were in my shoes.
Thank you in advance for your suggestions.
How can I use php to echo a page instead of linking to existing html page with hyperlink?
One example would be
<html>
<body>
click on this link to go back
</body>
</html>
Now, I don't want this link above to be a link to html page but to echo a page with php code when user clicks on click on this link to go back(to generate a page). This way, nobody can access a page after they logout.
Can php do this?
If someone logged out of your website or application I assume you will have a check whether or not this person is allowed to view the content.
Your question itself is very unclear to me. But it sound a bit if you want to do client-side coding (don't follow a link when it's clicked) with PHP which is not possible since PHP is a server side language. You will need Javascript to change the behavior of a link (for example, make an AJAX request which returns the content of another page).
Create a function, what the function should do is it should get triggered on a button click event and the code inside the function must send an curl request to the url you want and get back the html from it and echo it on your page
For answering the second part of your question!. you want no one to access the data without logging in so maintain $_SERVER['']; and sessions for users and validate if the user is inside a genuine session then show him content else no
I have different pages and scripts on my website. I want to show 1 URL in the adressbar for all the pages.
I have pages like:
www.example.com/index.php
www.example.com/map1/index.php
www.example.com/map1/map2/index.php
www.example.com/map1/map2/map3/index.php
I want that all these URLS should be shown like:
www.example.com
I have expirimented with my .htaccess script, but I cant get this working.
Can anybody help me with this problem? How can I show all the URL`s on my page like "www.example.com".
You could make www.example.com/index.php (which would be the default for www.example.com) be the only page that actually gets loaded fully, with all the others simply providing content to be loaded via ajax.
You could also make www.example.com/index.php contain only an iFrame or a frameset, such that clicks to other locations would only be to the nested frame, leaving the address bar always at www.example.com
You could also try taking "map1" and "map2" etc out of the URL and use them instead as post variables, or $_SESSION variables, or what have you.
Hide the Target URL of a Link in Status Bar
There are some instances where you have redirect the user through one page to get them to another page. There is a way to do this stealthily - without letting the user know that there was a redirect. Yes - it sounds evil - but it don't have to be. Say you have a click tracking software - you have to track each click the users make. To do that you need a redirecting page what will track the clicks. Hopefully, the following illustration will make things clearer...
Current Page->Page with the click counter->Destination Page
You don't want the user to see that you are passing through the middle page. Usually, the URL will flash in the address bar for just a second(or less) - so we don't have to worry about that. We just have to prevent the URL from appearing in the status bar when the user hovers over the link.
There are three methods to do this...
Change the status text
Hijack and stop the click event and redirect
page.
Make an Ajax call on click event.
Changing Status Text
This is the old method. This uses the window.status property to show a different URL to the user. Simple and easy method - but it rarely works now a days. This method has been abused by malicious sites a lot - so most browsers have disable this option. In Firefox, you can find that option at Tools -> Preferences -> Content -> Enable Javascript(click on the 'Advanced' Button) -> Change status bar text. If that's checked, you can use window.status to change the status bar text. But its disabled by default.
But if you still want to use this method(not recommended), this is how to do it...
<a href="click_counter.php?redirect_to=http://www.google.com/"
onmouseover="window.status='http://www.google.com/';return true;"
onmouseout="window.status='';">Go To Google</a>
Hijacking Click Event
In this method, when the user clicks on the link, the script captures the click event and stops it. This will prevent the browser from opening up the target page. Then we use location.href to go to the new page. Sample code below...
HTML Code
Go To Google
Javascript Code
<script type="text/javascript">
function init() {
document.getElementById("google-link").onclick=function(e) {
e=e||window.event;
stopEvent(e);
location.href="click_counter.php?redirect_to=http://www.google.com/";
return false;
}
}
window.onload=init;
</script>
Ajax Method
This is for all you web 2.0 fans. Ajax method simply makes a call to the counter server side script on the click event. This is perhaps the best method of all - as the counter URL doesn't appear at all. Needless to say, the server side script used here will be different from the one used in the other methods - there is no redirection here. The code is very simple as well...
HTML Code
Go To Google
**Javascript Code**
<script type="text/javascript">
function init() {
document.getElementById("google-link").onclick=function(e) {
jx("counter.php?url="+escape("http://www.google.com/")); //Use your favorite ajax library here.
}
}
window.onload=init;
</script>
I am new to the Yii framework and I would like to know the difference between $this->render() and $this->redirect().
Both can be used to retrieve a given page.
It looks like they do quite different things:
->redirect($url, ...)
redirect does a HTTP page redirect. Does not directly render a page.
->render($view, ...)
render outputs the named view. Does not terminate the current PHP request.
After the redirect, the browser will request another page that will have its own render() call. With a redirect, you will see the url change in your address bar and a different page. Unless of course you are redirecting to the page that you were already on.
->render('$view',...)
this is better used when you want to render same page beacause it's store action means it's cant change browser url.
->redirect('$relative_url',..)
this is better to use for show different page because it's change url as well as action.
I am working on a social network website similar to facebook. But, I am facing a rather confusing stage in the programming.
I am done with the register/login/logout pages/scripts, and you can view profiles with the www.mywebsite.com/profile.php.
Now, I want to do what facebook does and allow users to click links while on their profile page (info, notes, photos) but never actually leave www.mywebsite.com/profile.php — just the appropriate content is printed to the screen.
How is this done? I am not asking anyone to code this for me, just point me in the right direction!
You can use Ajax for this purpose.
Put the content that you want to replace in a div and using ajax replace that div and only send that content.
Are you trying to do something like this?
http://www.99points.info/2010/05/how-to-create-dynamic-content-loading-using-ajax-jquery/
That will have to be done via Javascript and Ajax.
A javascript function will fire when the link is clicked. An ajax request is sent to the corresponding php script which sends back a response to your javascript function. You then parse this response and place it on the screen.
If you go that way, have a fallback option that does not rely on javascript as well in case a user has JS turned off.
You Can use this reference...
function showdiv(id)
{
if(id)
{
var selected_offer="yourpagename.php"
HTML_AJAX.replace('divname',selected_offer);
}
}
call showdiv on onChange() function of your link..
For this, you need the technique known as Ajax, which is short for asynchronous JavaScript and XML. The basic idea is that when the user does something - in your case clicks on a link or button - instead of loading a page, a script runs that calls on a server side script to send back some data. This is sometime XML, but you can get other types of data back as well. The asynchronous part is that the user and the page can go on doing other things while waiting on your script to return the data you asked for.
There's a good book for beginners in Ajax that I read myself: Head First Ajax. Looks like you can pick up a used copy for about $10. It's a nice intro, has a quirky style that appeals to some, and the authors do whatever they can to keep your attention. Hardcore programmers probably won't like this one, but I sense you're a little newer to the game and this may be a good read. Otherwise, Google "learning Ajax" and there are a bajillion resources.
Good luck!
To respond to your comment, you can set up a "router" script that takes input and runs a specific function in response. This "router" function looks at the $_GET[] superglobal for a parameter like "action" and then calls a corresponding function. If not action parameter is sent over, the router calls a default function.
Now for a little more detail. Your page script would have 3 basic parts: The router, the various action functions, and the page template function. The router just calls the appropriate function from the action functions and passes the output into the template function. Here are a few examples.
The user arrives on the page, index.php. No action is specified, so the router finds $_GET['action'] == '' and it calls default_action(). This returns a welcome message, status, whatever, and the router passes this output to the function that displays your page, output included.
Now the user clicks a link/button for updates and arrives at index.php?action=update. $_GET['action'] == 'update', so the router calls update_action(). The output goes on to the template function for display.
Does this help you envision how you might accomplish this?
