Question

I am creating project in yii. I am having Poll table with the fields as-
-pollId
-pollQustion
-isActive
-publishDate

I want to check weather publishdate of poll is not greater than current date.
I am implementing as-

$CurrrentDate=new CDbExpression('NOW()');
if($record->publishDate < $CurrrentDate))
{
  some code......
}

But its not executing correctly. Code is executing even if publish date is greater than current date. So how to make this comparison in yii framework. please help me

Answer 1

PHP do not have a date format. When you compare $CurrentDate and $record->publishDate you compare strings. Well, for right compare you need to convert it to Unix’s timestamp

// here you set right date/time pattern 
// You need to explain CDateTimeParser for your pattern
// just easy use `strtotime` if you have 2012-12-12 12:12:12
$publishTimestamp = strtotime($record->publishDate);
// $publishTimestamp = CDateTimeParser::parse($record->publishDate, 'yyyy-MM-dd hh:mm:ss'); 
// if you need to use Hours and minutes just easy use `time()`
$currentDateTimestamp = time();
// $currentDateTimestamp = strtotime(date('Y-m-d H:i:s'));
// now we can compare
if ($publishTimestamp  < $currentDateTimestamp) {
   // do some 
}
