Sorry if I am asking the wrong Q for this forum. I want to use the GET method to pass 2 fields to a 2nd PHP script using HTML anchor,
via a query string, but I don't know how enter the fields to get them "evaluated". THe 2nd program keeps outputing the variable name and not the data in the variable.
Thanks for any help
Maureen

I'm not quite sure I follow you. Can you be more specific, perhaps show us some of your code or describe the process again?

When you pass variables via GET to a PHP script, those variables are available within PHP in the $_GET array.

For example, the URL for this topic ends in the query string: ?TOPIC_ID=5400

If this were a PHP script, you could access the value 5400 via $_GET['TOPIC_ID'].

There's lots of documentation in the PHP manual about this; in fact, it's in all the beginner tutorials.

Take care,

Yes, thank you for the reply. I am accessing the information using
$_GET[dataname] but the problem is that I did not pass this using
HTML's form I directly coded that data into the URL of the anchor tag. <a href=http:// bla bla bla?date=$date&time=$time>
When this link is pressed I go to the url of the new program and
i am able to get $_GET[date] but it is equal to "$date" rather then the value of $date which would be 2003/10/17. So it might be an HTML question and not appropriate for this site.

Hi Maureen,
<a href="http:// bla bla bla?date=$date&time=$time">
Is the correct syntax.

When you access this in PHP you should be quoting the array indice $_GET["date"] or $_GET['date'] .. the problem with not quoting the indice is PHP first assumes this is a defined constant and does not consider this a string unless no defined constant could be found! PHP would issue an error under error_reporting = E_ALL. I am not sure if there is a defined constant named 'date' but if there is this may be why you are having difficulty.

Also I'm not sure if I understand what you're getting at:
<a href="http:// bla bla bla?date=$date&time=$time#name">
                                    \----------------------/\----/
                                     url embedded html anchor
                                     arguments

Perhaps a snippet of code will help us to better understand what is going on.

I added an x to the variable names so that there will be no
conflict with any reserved words called date and time.

The variables are set to a date and time before being passed:
<?
    $datex = $_POST[programDate];
        $timex = $_POST[programTime];
  ?>
and I printed them out in pgm 1 to make sure they contained what I wanted
This is the anchor link in program 1:

<p><a href='show_addProgramAsana.php?datex=$datex&timex= $timex'>Identify Asanas</a></p>

Now this is the code in the 2nd pgm where I try to access the info:

<?

    print "$_GET[datex] = date and $_GET[timex] = time";
    include("yogaconnect.inc");
?>
 this is what is output:
$datex = date and $timex = time

Looking at your HTML, it seems that you're trying to use PHP variables while not within <?php and ?> delimiter tags.


Take care,

You are right nikolai, perhaps there is no way to really do this.
I put <? ?> around my variables, but now I get:
= date and = time
so I'll just rethink this and add a form with a hidden field.
Thanks

For the sake of understandability and adhearing to programming standards you should still quote your indices!

In a developement environment its extremely helpful to have error_reporting set to E_ALL, it helps catch many blunders. It tells you when a variable is not defined (When you may want one defined!). It also helps to tighten up the flow of a script since everything is defined very strict and explicitly there is less room for security exploitations. So that being said I strongly encourage you to move in that direction. Its troubleshooting & security benefits outweigh its nuisances.

$datex = $_POST['programDate'];
$timex = $_POST['programTime'];

This is acceptable because it is contained inside of quotes, e.g. the indices are treated like strings first and not constants:
print "$_GET[datex] = date and $_GET[timex] = time";

I would still prefer to do this instead:
print "{$_GET['datex']} = date and {$_GET['timex']} = time";

Also there is no predefined constant named date.

It can be done!

<p><a href='show_addProgramAsana.php?datex=<?php echo $_POST['programDate'];?>&timex=<?php echo $_POST['programTime']; ?>'>Identify Asanas</a></p>

Thanks for the E_ALL advice and the solution. It worked like a charm.
