Php header location redirect not working

Question

No idea why this is not working  Here is the code   if   isset   POST  cancel      amp  amp     POST  cancel       cancel          header  Location  page1 php        echo   POST  cancel        Instead of redirecting the page  this output s cancel to the webpage  It skipped over the redirect  Why  How can I fix this  page1 php is a real page located in the same folder as the current page  The above code is the very first lines of the php file  Nothing before it  Nothing  Not even whitespace

Make Sure that you don t leave a space before  lt  php when you start  lt  php tag at the top of the page

Use  obstart or try to use Java Script  put your obstart    into your top of the page  if   isset   POST  cancel      amp  amp     POST  cancel       cancel          header  Location  page1 php        exit          If you use Javascript Use  window location href  window location href example    if   isset   POST  cancel      amp  amp     POST  cancel       cancel                  echo   lt script type  text javascript  gt window location href    page1 php   lt  script gt           exit

Pekka answered my question in the comments  He didn t post an answer  so I am now  Use the exit   method after the header redirect  For some reason the rest of the code of the page continues to execute after the header   method redirect  When the rest of the code executes  the echo statement is outputted to the page  And you can t redirect using the header function after you output to the page  To avoid rest of the code from executing  use exit    Thanks Pekka   UPDATE  When using the web browser Internet Explorer  I have noticed that   POST  cancel   is not reliable  I am not exactly sure why this is  but I suspect IE posts additional variables on a form submit  specifically the variable  cancel  is posted  I solved this by using a variable name other than  cancel   The combination of using exit   and a unique variable name is working for me

I have experienced that kind of issue before and now I m not using header  Location  pageExample php    anymore  instead I m using javascript s document location   Change your   header  Location  page1 php      To something like this   echo   lt script type  text javascript  gt  document location    page1 php    lt  script gt      And what is the purpose of echo   POST  cancel    by the way   just delete that line if what you want is just the redirection  I ve been using that  lt script gt  every time and it doesn t fail me   -

This is likely a problem generated by the headers being already sent   Why  This occurs if you have echoed anything before deciding to redirect  If so  then the initial  default  headers have been sent and the new headers cannot replace something that s already in the output buffer getting ready to be sent to the browser   Sometimes it s not even necessary to have echoed something yourself    if an error is being outputted to the browser it s also considered content so the headers must be sent before the error information  if one of your files is encoded in one format  let s say ISO-8859-1  and another is encoded in another  let s say UTF-8 with BOM  the incompatibility between the two encodings may result in a few characters being outputted    Let s check  To test if this is the case you have to enable error reporting  error reporting E ALL   and set the errors to be displayed ini set  display errors   TRUE   after which you will likely see a warning referring to the headers being already sent   Let s fix  Fixing this kinds of errors    writing your redirect logic somewhere in the code before anything is outputted  using output buffers to trap any outgoing info and only release it at some point when you know all redirect attempts have been run  Using a proper MVC framework they already solve it    More  MVC solves it both functionally by ensuring that the logic is in the controller and the controller triggers the display rendering of a view only at the end of the controllers  This means you can decide to do a redirect somewhere within the action but not withing the view

Be very careful with whitespace and other stuff that may affect the  output  already done  I certainly know this but still suffered from the same problem  My whole  Admin php -file had some spaces after the closing php-tag    down the bottom on the last row     Easily discovered by adding     error reporting E ALL        which told me which line of code that generated the output

I had similar problem     solved by adding ob start    and  ob end flush          lt  php  ob start      require  engine vishnuHTML class php   require  engine admin login class php     html new vishnuHTML       isset   SESSION   session start           blah bla Code                               lt  div gt   lt  div gt   lt  php      ob end flush      gt    Think of ob start   as saying  Start remembering everything that would normally be outputted  but don t quite do anything with it yet    ob end clean   or ob flush    which either stops saving things and discards whatever was saved  or stops saving and outputs it all at once  respectively
