Why isnt it working

[darkness]

ive got part of a form
<textarea name="hwkset[0]" cols=35 rows=3></textarea>

im testing out parts as i add them to check they work before i go onto the next.

if($action == "insert" && $password == $pass) {

if ( isset($hwkset[0])) {
?>
There is hwk in the first 1
<?
}
else {
?>
There is no data there
<?
}
exit;
}

ive got that to check there is information in the field before it gets entered into the database, but wether there is something typed in or not the page says

"There is hwk in the first 1"

wot have a missed out or done wrong??

Because $hwkset[0] is set whenever the form is processed. If nothing is typed, it is an empty string.

Try: if ($hwkset[0] == "")

To treat string containing only spaces (i.e. " ") as an empty string, use: if (trim($hwkset[0]) == "")

Just to add to Vedrans point. TThe isset function only checks whether a variable exists.

As vedran pointed out whenever your run te script the first thing you do is declare the variable. So thats why it's always returning the same value.

Another way to check if there is anything ina field is to use the empty function e.g if(empty($variable_name))

this is more reliable as you are atually checking whats in the variable rather than just seeing if it has been set.

Any other questions just ask
