if $(action) { doesnt work

Hello,

For lots of you this might be a simple question, but i lost sweat and
tears searching for the answer.
I want to show some newsrecords from a database. But when i click on a
link with action="all" all the records have to show. Problem is that
when i dont give action in my tag it says variable action is not
declared. Strange is that i start my IF with if ($action) {

I give you code under this, if someone could help me i would be very
gratefull.

<?php
if ($action) // als er een actie ondergaan wordt
{ if ($action=="all")
{
$SQL_statement="SELECT * FROM nieuws ORDER BY news_id DESC";
$resultset=mysql_query($SQL_statement);
while ($data=mysql_fetch_array($resultset))
{
echo "<strong>".$data['news_date']."</strong><br/>";
echo $data['news_main']."<br/><hr/>";
}
} else
{
$SQL_statement="SELECT * FROM nieuws ORDER BY news_id DESC";
$resultset=mysql_query($SQL_statement);
while ($data=mysql_fetch_array($resultset))
{
echo "<strong>".$data['news_date']."</strong><br/>";
echo $data['news_main']."<br/><hr/>";
}
}
} else {

$SQL_statement="SELECT * FROM nieuws ORDER BY news_id DESC";
$resultset=mysql_query($SQL_statement);
while ($data=mysql_fetch_array($resultset))
{
echo "<strong>".$data['news_date']."</strong><br/>";
echo $data['news_main']."<br/><hr/>";

}
}
mysql_close();
?>

Hi,

Try wrapping the variable $action with the isset() function. Like
so...

if(isset($action)

Regards,

Kieran.

Tnx Kieran, it worked with the isset function but now he doesnt do the
trick when the action is given )-; , i ll keep on searching, maybe i
have to $get the action variable?
