[RESOLVED] Passing variables via a hyperlink

[snoopgreen]

Hello everyone

im hoping someone may be able to advise me how i would complete this task?

well the code i have is shown below:

While ($rec = mysql_fetch_array($result)) {
	echo("<tr>");
	echo("<td align=\"center\"><A HREF=\" LMoreProgInfo.php \">" . $rec["prog_title"] . "</A></td>");
	echo("<td><div align=\"center\">" . $rec["prog_ucas"] . "<br>\n</div></td>");
	echo("<td><div align=\"center\">" . $rec["prog_type"] . "<br>\n</div></td>");

What i want to do is to be able to pass the prog_title value clicked on to the LMoreProgInfo.php page
so that i can create SQL statements using that value to show more data about it?

Will i need to start a session at the top of page, then register the value somewhere and somehow pass that variable when the user clicks on the link?

any help on this problem would be greatly apprecaited
thanks in advance

If you want to pass the data in the url then the format in html is as follows

http://www.mydomain.com/page.php?var1=val1&var2=val2

You build that as a string and then insert it into your html href in the normal way. The target page then pulls the data out through the $_GET variable array

$var1 = $_GET['var1'];
$var2 = $_GET['var2'];

$var1 will now contain the val1 in the url.

thanks roger

could i just ask what you mean by

You build that as a string and then insert it into your html href in the normal way.

the code ive got in my HREF is shown below:

echo("<td align=\"center\"><A HREF=\" LMoreProgInfo.php?progTitle=prog_title \">" . $rec["prog_title"] . "</A></td>");

and the code i have on LMoreProgInfo.php is below:

<?php
$progTitle = $_GET['progTitle'];

echo("$progTitle");
?>

but this is just outputting $progTitle onto the screen

Im i on / around the right lines?
any more help would be great

thanks again

I see it's been answered while I was writing

[rincewind456]

    echo("<td align=\"center\"><a href=\" LMoreProgInfo.php?prog_title=\"". $rec["prog_title"] . "\">" . $rec["prog_title"] . "</a></td>"); 

will pass it as a $_GET variable

[Jack_McSlay]

I think it's because you told on the href to pass "prog_title", not your program title

echo "<td align=\"center\"><A HREF=\" LMoreProgInfo.php?progTitle={$rec['prog_title']} \">" . $rec["prog_title"] . "</A></td>"; 

(yes, the ()s are unnecessary for echo)
