doni49 Posted April 11, 2008 Share Posted April 11, 2008 Don't forget that the header command has to be sent before anything at all is sent to the browser. Link to comment https://forums.phpfreaks.com/topic/100569-redirecting-browser/#findComment-514361 Share on other sites More sharing options...
brad12345 Posted April 11, 2008 Author Share Posted April 11, 2008 Warning: Cannot modify header information - headers already sent by (output started at /home/it224/bradk/public_html/assignment1/newPatient.php:11) in Error coming back? also a note it is not just a php script, the php script is inside the html, should this effect it?

Yes--that error message is exactly what you get if you use the header cmd and have already sent anything to the browswer.

Northern Flame Posted April 11, 2008 Share Posted April 11, 2008 put this code on top of the html <?php if (isset($_POST['addPatient'])){ if(empty($petName) || empty($petSpecies) || empty($petBreed)) { header("Location: http://kate/~bradk/newPatient.php"); } //Adding patient into database $createQuery2 = "INSERT INTO tblPatientBK (petName, petSpecies, petBreed, petAge, petWeight, ownerID) VALUES ('$petName','$petSpecies','$petBreed','$petAge','$petWeight','$ownerID')"; $result = mysql_query($createQuery2); //preforming mysql $createQuery2 //displaying message to let user know the task has been carryed out and the patient has been added echo ("Thank you<p>Your new patient has been added successfully.<p>"); echo("<a href='index.php'><font color='blue'>Return to home page</font></a>"); } else ?> Link to comment https://forums.phpfreaks.com/topic/100569-redirecting-browser/#findComment-514373 Share on other sites More sharing options...
Cagecrawler Posted April 11, 2008 Share Posted April 11, 2008 You can use output buffering to stop the html being sent before the header. http://uk.php.net/manual/en/function.ob-start.php Link to comment https://forums.phpfreaks.com/topic/100569-redirecting-browser/#findComment-514379 Share on other sites More sharing options...
