try:

    header(&#39;Location: &#39; . $_SERVER[&#39;HTTP_REFERER&#39;]);

Note that this may not work with secure pages (HTTPS) and it&#39;s a pretty bad idea overall as the header can be hijacked, sending the user to some other destination. The header may not even be sent by the browser.

Ideally, you will want to either:

* Append the return address to the request as a query variable (eg. ?back=/list)
* Define a return page in your code (ie. all successful form submissions redirect to the listing page)
* Provide the user the option of where they want to go next (eg. Save and continue editing or just Save)

Its so simple just use this 

    header(&quot;location:javascript://history.go(-1)&quot;);

Its working fine for me

Just a little addition:
I believe it&#39;s a common and known thing to add `exit;` after the header function in case we don&#39;t want the rest of the code to load or execute...

    header(&#39;Location: &#39; . $_SERVER[&#39;HTTP_REFERER&#39;]);
    exit;

You have to save that location somehow.

Say it&#39;s a POST form, just put the current location in a hidden field and then use it in the `header()` Location.

Just try this in Javascript:

     $previous = &quot;javascript:history.go(-1)&quot;;

Or you can try it in PHP:

    if(isset($_SERVER[&#39;HTTP_REFERER&#39;])) {
        $previous = $_SERVER[&#39;HTTP_REFERER&#39;];
    }

Storing previous url in a session variable is bad, because the user might right click on multiple pages and then come back and save.

unless you save the previous url in the session variable to a hidden field in the form and after save header( &quot;Location: save URL of calling page&quot; );

I know this question focuses specifically on headers, but in case anyone would like to do it inside a button, this would suffice.

    &lt;button type=&quot;button&quot; class=&quot;btn btn-default&quot; onclick=&quot;javascript:history.go(-1)&quot;&gt;Back&lt;/button&gt;

I have a profile in my pom.xml which should be always active unless it is explicitely deactivated (-P !firstProfile).
I solved this by using the activeByDefault flag:

    &lt;profiles&gt;
      &lt;profile&gt;
        &lt;id&gt;firstProfile&lt;/id&gt;
        &lt;activation&gt;
          &lt;activeByDefault&gt;true&lt;/activeByDefault&gt;
        &lt;/activation&gt;
        ...
      &lt;/profile&gt;
    &lt;/profiles&gt;

Now in the same pom.xml I have a second profile defined this should only be active if the profile is really activated (-P secondProfile).
So the default behaviour is: firstProfile active, secondProfile inactive.
At some other point I would like to activated the second profile in addition to the first profile.
Now the problem is that if I do that with &quot;-P secondProfile&quot; the firstProfile unfortunately gets deactivated.
The Maven documentation states this:

&gt; ... 
&gt; This profile will automatically be
&gt; active for all builds unless another
&gt; profile in the same POM is activated
&gt; using one of the previously described
&gt; methods. All profiles that are active
&gt; by default are automatically
&gt; deactivated when a profile in the POM
&gt; is activated on the command line or
&gt; through its activation config. 
&gt; ...

Is there somehow a possibility how to keep the firstProfile always active (without having to declare it in the settings.xml)?

How to keep Maven profiles which are activeByDefault active even if another profile gets activated?

My registration form, which is a form for the Users model, takes a string value for company. However, I have just made a change such that users belongs_to companies. Therefore, I need to pass an object of Company to the Users model. 

I want to use the string value from the form to obtain the an object of Company:

    @user.company = Company.find_by_name(params[:company])

I believe the above works, however the form is passing the :company (which is string) into the model when I call:

    @user = User.new(params[:user])

Therefore, I want to know (and cannot find how) to remove the :company param before passing it to the User model.

I imagine this is pretty simple, but can&#39;t figure it out. I&#39;m trying to make a few pages - one which will contain results selected from my mysql db&#39;s table for today, this week, and this month. The dates are entered when the record is created with `date(&#39;Y-m-d H:i:s&#39;);`. Here&#39;s what I have so far:

day  where date&gt;(date-(60*60*24))

     &quot;SELECT * FROM jokes WHERE date&gt;(date-(60*60*24)) ORDER BY score DESC&quot;

week  where date&gt;(date-(60*60*24*7))

     &quot;SELECT * FROM jokes WHERE date&gt;(date-(60*60*24*7)) ORDER BY score DESC&quot;

month (30 days)   where date&gt;(date-(60*60*24*30))

     &quot;SELECT * FROM jokes WHERE date&gt;(date-(60*60*24*30)) ORDER BY score DESC&quot;


Any ideas would be much appreciated. Thanks!

I&#39;m using the dompdf plugin for codeigniter: [http://codeigniter.com/wiki/PDF_generation_using_dompdf/][1]

to generate pdfs from a form. This works on localhost, but on the live server I get this in the error log:

    Directory index forbidden by Options directive: /var/www/vhosts/domain.co.uk/httpdocs/mm/userdata/account1/invoices/


Any idea what this means? I&#39;ve searched for answers, and found a few that suggest editing the httpd.conf, however I don&#39;t have access to this.

I&#39;ve also tried adding a blank index.html file to the root and document directory (as also suggested elsewhere, but to no avail).

Any help greatly appreciated.

Thanks!

I want to do a conditional in PHP for the different versions of Internet Explorer along the lines of:

`if($browser == ie6){ //do this} elseif($browser == ie7) { //dothis } elseif...`

I have seen many variations on similar code, but looking for something super simple that is very easy to code to do some simple if and else and do different things.

Thanks

EDIT: I need this to show some different messages to users so CSS conditionals etc are no good.

I&#39;m trying to find a method to redirect my request from a filter to the login page but I don&#39;t know how to redirect from servlet. I&#39;ve searched but what I find is `sendRedirect()` method. I can&#39;t find this method on my response object in the filter. What&#39;s the cause? How can I solve this?

Is it possible to set up a basic HTML page to redirect to another page on load?


Redirect from an HTML page

What is the best way to do a redirect in an &lt;code&gt;ActionFilterAttribute&lt;/code&gt;.  I have an &lt;code&gt;ActionFilterAttribute&lt;/code&gt; called &lt;code&gt;IsAuthenticatedAttributeFilter&lt;/code&gt; and that checked the value of a session variable.  If the variable is false, I want the application to redirect to the login page.  I would prefer to redirect using the route name &lt;code&gt;SystemLogin&lt;/code&gt; however any redirect method at this point would be fine.

Redirect From Action Filter Attribute

The following `attempt_login` method is called using Ajax after a login form is submitted.

    class AccessController &lt; ApplicationController
      [...]
      def attempt_login
        authorized_user = User.authenticate(params[:username], params[:password])
        
        if authorized_user
          session[:user_id] = authorized_user.id
          session[:username] = authorized_user.username
          flash[:notice] = &quot;Hello #{authorized_user.name}.&quot;
          redirect_to(:controller =&gt; &#39;jobs&#39;, :action =&gt; &#39;index&#39;)
        else
          [...]
        end
      end
    end

The problem is that `redirect_to` doesn&#39;t work.

How would you solve this ?

All the questions I&#39;ve found are related for a successful login with the helper
`after_sign_in_path_for(resource)`

I have a login form in the index of the site, and when the login fails it redirects to &quot;users/sign_in&quot;

But how can I redirect to my &quot;site#index&quot; when the login fails?

Devise redirect after login fail

I use an async task to upload an image and get some results.

While uploading the image I see a progress dialog, written in onPreExecute() method like this:
    
        protected void onPreExecute() { 
             uploadingDialog = new ProgressDialog(MyActivity.this); 
             uploadingDialog.setMessage(&quot;uploading&quot;); 
             uploadingDialog.setCancelable(true);
             uploadingDialog.show();
        }

Ok when I press the back button, obviously the dialog disappears because of the setCancelable(true).

But (obviously) the async task doesn&#39;t stop.

So how can I fix this? I want to cancel both dialog and async task when I press the back button. Any ideas?

Android: Cancel Async Task

When the BACK button is pressed on the phone, I want to prevent a specific activity from returning to its previous one.

Specifically, I have login and sign up screens, both start a new activity called `HomeScreen` when successful login/signup occurs. Once HomeScreen is started, I want to prevent the users from being able to return to the login or sign up screens by pressing the BACK key. 

I tried using `Intent.FLAG_ACTIVITY_NO_HISTORY`, but since the application has Facebook integration, when the &#39;Login with Facebook&#39; is used, Facebook should return to the initial login screen, therefore I should keep a history of these activities.

I thought of overriding the behaviour of the BACK button on `HomeScreen` to directly finish an application when the button is pressed and I used

    @Override
	public void onBackPressed() {
		finish();
	}

but that also does not work.


How to prevent going back to the previous activity?

I am developing an application that when the button is pressed, it opens a dialog with OK and Cancel buttons.

It works fine.

When the user presses the back button, I am handling this as follows

    public boolean onKeyDown(int keyCode, KeyEvent event) 
    {
        if ((keyCode == KeyEvent.KEYCODE_BACK)) 
    	{
    	
    	}
     return super.onKeyDown(keyCode, event);
    }

But the above method is not called. How can I handle this?

How to handle Back button with in the dialog?

I am trying to prevent an AlertDialog box from closing when pressing the back button in Android. I have followed both of the popular methods [in this thread][1], and with System.out.println I can see that in both cases the code executes. However, the back button *still* closes the dialog box.

What could I be doing wrong? Ultimately I&#39;m trying to prevent the back button closing a dialog box - it is a disclaimer that is displayed the first time the app is run and I don&#39;t want the user to have any option but to press the &quot;Accept&quot; button in order for the app to continue.

Prevent back button from closing a dialog box

In normal text editors [with all due respect to Vim] there is a shortcut &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Z&lt;/kbd&gt; when you have done something nasty and want to return to the previous version of the text. Like BACK button in Word. I wonder how can you achieve this behaviour in Vim.
