IF statement

stevekrazykats

What is wrong with this statement?

if{($profile_employstatus == 0) || ($profile_employstatus == $user->profile_employstatus)} && {($profile_tags == 0) || ($profile_tags == $user->profile_tags)} {?> code to execute }

Its obviously something pretty fundamental. Sorry for the noobness.

Yes, it is pretty fundamental since it is a syntax error. You probably wanted to write:

if (($profile_employstatus == 0 || $profile_employstatus == $user->profile_employstatus)
    && ($profile_tags == 0 || $profile_tags == $user->profile_tags)) {

That is very helpful, I can see my mistake. So now I have:

if (($profile_employstatus == $blank || $profile_employstatus == $user->profile_employstatus)
   && ($profile_tags == $blank || $profile_tags == $user->profile_tags))

which would work except that $profile_tags is a text string and $user->profile_tags is an array of text strings. I want to execute code if $profile_tags == ANY of the strings contained within the array $user->profile_tags.

If you can help me with that, I'd be a lot nearer where I want to be.

See the [man]in_array/man function.

Thanks, that is clearly the direction I need to go.

I'm trying:

if (($profile_employstatus == $blank || $profile_employstatus == $user->profile_employstatus)
   && ($profile_tags == $blank || (in_array($profile_tags,$user->profile_tags,TRUE))))

But it returns
warning: in_array(): Wrong datatype

So I expect I have to look into different types of arrays and maybe the SQL.

Okay I figured that one out, I just needed to update the database. I love learning this stuff even though I'll never use it again. I really have a geek inside me.

Last question:

Is there a way to echo all the contents of an array with one simple command?

stevekrazykats

I think I can manage with:

print_r(array_values($user->profile_tags));

My array $user->profile_tags is multi-dimensional. It might be created thus:

$user->profile_tags = array(array('Whisky', 0), array('Vodka', 0), array('Gin','Gin'))

For someone who only liked Gin. I need to search the array for 'Gin' but only the values, not the keys. Using in_array("Vodka", $user->profile_tags) will return TRUE here when I need it to return false.

I have tried this function:

<?
 // Function for looking for a value in a multi-dimensional array
function in_multi_array($value, $array)
{   

    foreach ($array as $key => $item)
    {       

        // Item is not an array
        if (!is_array($item))
        {
            // Is this item our value?
            if ($item == $value) return true;
        }

    // Item is an array
    else
    {
        // See if the array name matches our value
        //if ($key == $value) return true;

        // See if this array matches our value
        if (in_array($value, $item)) return true;

        // Search this array
        else if (in_multi_array($value, $item)) return true;
    }
}

// Couldn't find the value in array
return false;
}
?>

But for some reason it does not work at all.
