navigation using php

[veena]

Hi,
I have a HTML form to input the values. On clicking the submit button, I would like to do the following things:
1. Validate the input data
2.upon validating on success, insert the data to postgresql database table
3. Take the control to a different page to show the user all the inputted information and continue further

Since validation should be done on the same file where I have the form . so in the form post I need to have
<FORM ACTION="<?=$_SERVER['PHP_SELF']?>" METHOD="POST" name="registration">

In this case how can I call a different page on successfully inserting the values to table??

Without doing this, I can't continue any further. Any help as early as possible will save me!!

OK after validating and inserting into the database simply put

header("location:new location here");

BTW make sure that you are not outputting anything to the browser before you use that snippet. That includes whitespace

This general logic should do the trick:

 

if ($_POST['process']) {

  if (validate_data()) {
    //  insert data into database

// redirect to another page
header("Location: wherever");
  }
  else {
    //redisplay form with values and error msg
    display_form($errorMsg);
  } 

}
else {

  //display form without error msg
  display_form("");

}


function validate_data()
{
  // validation functions here
{


function display_form($errMsg)
{
  print "
<FORM NAME=\"myForm\" METHOD=\"post\" ACTION=\"$_SERVER['PHP_SELF']\">
<INPUT NAME=\"process\" TYPE=\"hidden\" VALUE=\"1\">
";

  // other form fields here

  print "</FORM>";
  print $errMsg;
}
