Passing variables throuegh URL

abhilaash

Hello....

I was trying to pass a variable through an URL and retrive the variable data in the page mentioned in the URL. But I had a futile attempt.

CODE SNIPPET IS AS FOLLOWS:

$url = "results.php?start=".$nstart;
echo "<a href='$url'>Next</a>";

NOTE:
This hyperlink is placed on the page results.php and I want it get the variable on the page results.php through URL when I click the NEXT link or URL mentioned here.

Got it?

The purpose of this URL is retrieving data from Database and display the data based on a specific count in several pages and navigate using NEXT and PREV links(implemented thru a function).

CAN ANYBODY PLEASE GIVE ME A HELPING HAND?
THNX

Sure:

Remove the period '.' preceeding your var and the quote around it:

$url = "results.php?start=$nstart;
echo "<a href='$url'>Next</a>";

Instead of:
$url = "results.php?start=".$nstart;
echo "<a href='$url'>Next</a>";

HTH :-)

No, that'll just get you a parse error - the way it was looked fine.

But I take it it's not working. What's happening instead? Does $nstart have the value it's supposed to (i.e. does it appear in the URL properly)? Need the info.

I didn't get a parse error...I got a blank page with the html header.

Ya $nstart has got a value.

$nstart = $start + $record;
Where $start=0 and $record = 1 So $nstart bcomz 1;

After submitting the URL I get something like this on the address bar
http://localhost/../.../address/results.php?start=1

But I cant get the value of $start from the URL.

How are you trying to access $nstart on results.php? If register_globals is off then you will need to use $_GET['nstart']

I tried this way also..

$url = "results.php?start=$nstart";
echo "<a href='$url'>Next</a>";

In php.ini file register_globals is ON...
and trcaks_vars is also ON

I fail to get the value of start in other page.....I am trying to retrieve it using the variable $start which I hope will created automatically from the URL in the same way as GET variables are created. But $start is giving no value. It is not even set.

single quotes usualle make strings literal.. try this:

$url = "results.php?start=$nstart";
echo "<a href=\"$url\">Next</a>";

and i notice you refer to the variable $start and in the code you use $nstart .. just makin sure you have the correct variable name.
