Question

The following code is returning a syntax error in the second elseif statement:

if(($Rec["gradyear"] = $mydate[year] && $mydate[month] IN ("January","February","March","April","June","July")) || ($Rec["gradyear"] = $mydate[year] -1 && $mydate[month] IN ("August","September","October","November","December"))) {
    $bgcolor="#00FF00";
} elseif(($Rec["gradyear"] = $mydate[year] -1 && $mydate[month] IN ("January","February","March","April","June","July")) || ($Rec["gradyear"] = $mydate[year] -2 && $mydate[month] IN ("August","September","October","November","December")))  {
    $bgcolor="#FFFF00";
} elseif(($Rec["gradyear"] = $mydate[year] -2 && $mydate[month] IN ("January","February","March","April","June","July")) || ($Rec["gradyear"] = $mydate[year] -3 && $mydate[month] IN ("August","September","October","November","December"))) { 
    $bgcolor="#FF0000"; $fontcolor="#FFFFFF";
}

For the life of me, I cannot locate it. Any help will be greatly appreciated.

Also, I apologize in advance if I'm not including enough information. This is my first time posting here, so please be gentle. :)

Answer 1

In is not valid.

Use in_array in php.

For example:

in_array($mydate[month] ,
array("January","February","March","April","June","July")
);
