I am using PHP/MySql

I am building an html table at runtime and populating it using values from my db. I want these to be links.

How can I pass the link label to another page for processing.

let's say we have the following table:

  COMMERCE    | INDUSTRY

  AGRICULTURE | LAW

that's a table with 2 rows and 2 columns populated with values from database(i.e COMMERCE, INDUSTRY etc). I have made these table values links to a certain document which should process using the value clicked by user.

Lets say a user clicks on COMMERCE link, I want the value COMMERCE to be passed to the document. When a user clicks on INDUSTRY, I want the value INDUSTRY passed to the document being launched.

Ok.

So when you are generating the table, you can use ...

echo "<a href=\"handler.php?link=$db_field_you_want_goes_here\">$db_field_you_want_goes_here</a>";



The handler.php file has

if (isset($_GET["link"]))
 {
// The value of $_GET["link"] reflects the chosen value.
 }

If you are using an earlier version of PHP (one without the super globals), then you may find that $link is already available and can be used as

if (isset($link))
 {
// The value of $link reflects the chosen value.
 }

Regards,

Richard.

P.S. I thought I'd already replied to this! Obviously not!

Is handler.php a predefined script or user-defined script?

Where should I place the target page, Should I replace handler.php with my own page.

If you have a page that you want to use as the handler then use that. If you page is called index.php, then ...

echo "<a href=\"index.php?link=$db_field_you_want_goes_here\">$db_field_you_want_goes_here</a>";

In index.php, you need to test on $_GET["link"] to see if it is set (isset()) and what its value is.

You can then handle the value sent to you.
