eval(), checkbox and isset()

[FAVIO007]

Hi...
I have a problem with that.
I am new in PHP.

I want to make a code with checkbox (dinammically), and I ask for isset() in this form.

I want to know if the checkbox was checke in the form.

Below is a code of the PHP.

Special thanks to all !!!

<?php
//Looking for
$qry_lookingfor = "SELECT lookingfor_ID";
$qry_lookingfor .= " FROM j_tlookingfor";
$rs_lookingfor=mysql_query($qry_lookingfor,$link_sql);
?>

<?php
while ($rw_lookingfor=mysql_fetch_object($rs_lookingfor))
{
$str='isset('.'$'.'chk_lookingfor'.$rw_lookingfor->lookingfor_ID.')';
if (isset($str)) echo 'pepe';
}
?>

this is how you can check if a checkbox has been checked:

<?php
if (IsSet($submit) {

if (IsSet($checkb) && $checkb == "yes") echo "the checkbox has been checked";
else echo "the checkbox has not been checked";

}
else {
?>
<form name="blabla" action="get" method="<?php echo $PHP_SELF;?>">
<input type="checkbox" name="checkb" value="yes">
<input type="submit" name="submit" value="Press me! press me!">
</form>
<?php
}
?>
