On this event go to this url , else go here

问题

I am trying to write an if statment in php but I am not sure how to redirect the user to another url on a condition. What I am trying to do is :

 if $member = $notmember
 go here index.php?option=com_jumi&view=application&fileid=6&Itemid=174
else
go here index.php?option=com_jumi&view=application&fileid=6&Itemid=124

I am not sure how to redirect to another url though ?.

回答1:

You could use header. Something like this:

if ($member == $notmember)
   header("Location: index.php?option=com_jumi&view=application&fileid=6&Itemid=174");
else
   header("Location: index.php?option=com_jumi&view=application&fileid=6&Itemid=124");

If after the else, you have more code, you should use exit() in order to prevent of your code to keep executing.

Have a look at the PHP official website. And especially take notice to the following:

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP.

You can use header():

<?php
if ($member == $notmember) {
   header("Location: http://xx.com");
   exit;
} else {
   header("Location: http://yy.com");
   exit;
}
?>

Don't forget exit, otherwise the rest of you php script will be executed.

For more information about the header function see: http://php.net/manual/en/function.header.php

回答3:

if( $member == $notmember) // use TWO equals signs, otherwise you're just assigning
    header("Location: index.php.......");
else
    header("Location: index.php.......");
exit; // stop script execution

回答4:

<?php if ($member == $notmember) {?>
<script type="text/javascript">window.location = "index.php?option=com_jumi&view=application&fileid=6&Itemid=174"</script>
<?php } else {?>
<script type="text/javascript">window.location = "index.php?option=com_jumi&view=application&fileid=6&Itemid=124"</script>
<?php } ?>

this is php w/ js solution

回答5:

you can use this too:

if ($member == $notmember)
  echo "<script>window.location = 'index.php?option=com_jumi&view=application&fileid=6&Itemid=124";
else
  echo "<script>window.location = 'index.php?option=com_jumi&view=application&fileid=6&Itemid=124'</script>";
