isset trouble

rockyracoon · 07-23-2002, 02:15 PM

I want the ECHO to remain, but it dissapears when I set $value2. Any ideas?

if (isset($value1)){
echo "please Stay!"
}

...and later on

if (isset($value2)){
echo "nope, sorry!"
}

A bit more code or explaining of what you want to achieve would be helpful..

The thing you can't get to work is it anything like this:

PHP Code:


			
<html>

<?php

  if(isset($value1))

      echo "Welcome to ";

?>

My place is so rocking.. And I'm



<?php

  if(isset($value2))

    echo " Sorry ";

?>

with ....

</html>

or is it anything like

PHP Code:


			
<html> 

<?php

if(isset($value1))

{

  echo "Welcome to ";

  unsset($args);

}

?>

My site is so rocking... An I'm 

<?php

if(isset($value2))

  echo " Sorry ";

?>

with...

</html>

Because the last one, will not have a $value2 in it, since you've unset every argument parsed to the page..

But as I started out with, a few more lines or explaining will sure help the understanding of why/how you are trying this..

Uh-oh.... i was wrong. heres the code:

if (isset($clicked) && $value == "1"){
mysql_query("INSERT INTO popfiller (desc) VALUES ('$desc')");
$cell1 = "yes";
}
if (isset($cell1)){
echo "this will dissapear";
}
echo "
----------------HTML HERE----------------
";
if (isset($clicked) && $value == "1"){
mysql_query("INSERT INTO popfiller (desc) VALUES ('$desc')");
$cell2 = "yes";
}
if (isset($cell2)){
echo "when this appears";
}

Why not have:

PHP Code:


			
<?php

echo "<html><body><!-- other settings -->";

if (isset($clicked) && $value == "1"){

mysql_query("INSERT INTO popfiller (desc) VALUES ('$desc')");

$cell1 = "yes";

}

if (isset($cell1)){

echo "this will dissapear";

}

echo "

Other html part of the page...

";

if (isset($clicked) && $value == "1"){

mysql_query("INSERT INTO popfiller (desc) VALUES ('$desc')");

$cell2 = "yes";

}

if (isset($cell2)){

echo "when this appears";

}

Since if you have the <html> in the ----HTML HERE--- it will send a header to the browser, instructing it to expect the rest of the page as HTML where the "this will.." part is expected as raw text.

Since we know, every thing send from the page, is as html, we might aswell instruct the viewer that this will be html, and avoid any possible error in that part.
