Im having trouble transferring data from this code after using PHP_SELF. I try to pass the parameters via the header but I just cant get it to work. If anyone knows, could u just provide a few tips please.
Thanks in advance
Kind regards

if ($submit) {
header("location: phd_student_addrecord2.php?student=$student&sponsor=$sponsor");

}

else
{
echo "
<HEAD>
<TITLE>Add a student record</TITLE>
</HEAD>

<BODY>
<h1>Add a new student record </h1>

<tr> 
  <td valign=top width=\"118\"><strong>Student</strong></td>
  <td valign=top width=\"505\"> 
    <input type=\"text\" name=\"student\" value=\"$student\" size=30>
  </td>
</tr>




<tr> 
  <td valign=top width=\"118\"><strong>Sponsor</strong></td>
  <td valign=top width=\"505\"> 
    <INPUT type=\"text\" name=\"sponsor\" value=\"$sponsor\" size=70>
  </td>
</tr>




<tr> 
  <td width=\"118\"> 
    <input type=\"submit\" name=\"submit\" value=\"submit\">
  </td>
</tr>

</table>
</FORM></body>";
}

what exactly is the problem? are you printing anything else before your header call? you might try using this for your form action as well:

print ("<FORM NAME='distSel' METHOD=POST ACTION='".basename($PHP_SELF)."'>\n");

the basename function is recommended in the docs.

When sending form values back to the same page, you can just set the form ACTION="" (i.e. leave it black) This is a feature of HTML.

Perhaps this helps, but maybe I'm misunderstanding what you're trying to do. Dont know what the header location bit is all about.

Sorry, i didn't make my question clear, I tried to simplify the code to make it easier to read. My problem is that when transferring data from this code (full source below) after using $PHP_SELF I try and use default.php?a=$a&b=$b&c=$c but it doesn't work.
Any hints?

Kind regards,

maybe I'm just a bit dull this morning, but I'm not sure I'm getting your problem. Are you trying to just use a link from one page to call the page you have shown the source code for? Then the problem is that it is not processing the header request? if so, I think it is because you are not giving the $submit variable a value as you pass it in the link. make sure you pass a value for submit and see if that works.

Sorry, im not good at explaining it. the page I provided source for is called php_students_addrecord1.php.

I'm using the header request to pass the values which were entered in the form to php_students_addrecord2.php (i havent provided source for this page).

The reason 'PHP_SELF' is used is so I can check the values provided for some of the 'Form' entries were input. I think this is a good way to do it but im not sure.

The problem is - I can't get it to make up a header request. For instance, i need to constuct a link something like:

php_students_addrecord2.php?student=$student&supervisor=$supervisor

I'm not sure why I cant get it to pass these parameters properly. I need to pass these variables so that the next page 'php_students_addrecord2.php' can enter them in a database.

Not sure what you mean by make sure I pass a value for submit. Why is this necessary?

Thanks again in advance
Kind regards

hmmm. OK, let mesee if I get this straight:

1) server prepares and serves php_students_addrecord1.php

2) user inputs values

3) user hits submit button

4) action on form of php_students_addrecord1.php is PHP_SELF so server again serves up php_students_addrecord1.php, now with some values attached (via POST)

5) php_students_addrecord1.php notes values have been submitted and should redirect (via header) to php_students_addrecord2.php

6) php_students_addrecord2.php gets served up but values aren't there

is this correct? wait, I just reread your post, you are saying #5 isn't happening. If so, I assume this is because your if ($submit) statment isn't not evaluating to TRUE and therefore not being processed. This then means that $submit has no value, which raises the question of how php_students_addrecord1.php is being submitted and what the value of $submit is upon its submission. From your provided code, it appears correct. Hmmm....

have I got the gist? Are we getting anywhere?
