So i'm having a bit of a problem with having my PHP run a command if multiple variables exist. I made a simple version for people to see what i'm trying to fix easier. Thanks in advance to anyone who can help :)
<?php
if ((isset($finalusername)) && if (isset($finalpassword)) && if (isset($finalemail)))
echo "This will save.";
?>
if (isset($finalusername, $finalpassword, $finalemail))
You don't need to place the multiple if in there.
if (isset($finalusername) && isset($finalpassword) && isset($finalemail)) {
// ...
}
In fact, I'd even do it like so...
if (isset($finalusername, $finalpassword, $finalemail)) {
// ...
}
If multiple parameters are supplied then isset() will return TRUE only if all of the parameters are set.
So you can do this way:
if (isset($finalusername, $finalpassword, $finalemail)) {
echo "This will save.";
}
So this might be a good solution for much more than some variables:
// INTI ARRAY
$arr_final = array(
'username' => !empty($finalusername) ? $finalusername : false,
'password' => !empty($finalpassword) ? $finalpassword : false,
'email' => !empty($finalemail) ? $finalemail : false,
'more_stuff' => !empty($morestuff) ? $morestuff : false,
);
$bol_isValid = true;
$arr_required = array('username','password');
foreach ($arr_final as $key => $value) {
if ( (in_array($key, $arr_required)) && ($value === false) ) {
$bol_isValid = false;
break;
}
}
Try with this:
if (isset($var1))
{
if (isset($var2))
{
// continue for each variables...
}
}
