I am programing a specialized review database and one of the items I want to capture is the DATE when the person was at the place they are reviewing. I am planning to add a series of pick lists for "Month", "Day", and "YEAR" but I would like to be able to convert this mm-dd-yyyy data into a MYSQL date format.
The reason this is important is for searching so that I can allow my members to search for reviews for "latest visit first" or "All reviews from visits in the past year" where the Timenow()-$visitdate type of code could be used...
So, can someone help me understand how I can convert Month-Day-Year values to a MYSQL friendly date format that I can use for this?
Would it be possible for me to add dates with some of this information missing (say a user knows they are reviewing something from June of 2005)?
I found the following as a reference but this is just a little complicated for an amateur like myself:
http://www.databasejournal.com/featu...0897_2172731_1
So, if I use php to create a text string as (perhaps as follows)
// $yyyy = year as input
// $mm = month as input
// $dd = day as input
$date_of_visit .= $yyyy;
if ($mm)$date_of_visit .= '-' . $mm;
if ($mm AND $dd)$date_of_visit .= '-' . $dd;
Then, can I use the following to save this date into my database?
INSERT INTO review_table(date) VALUES($date_of_visit)
Now, if I do this, will this allow me to use this data to perform calculations and such using the TIMENOW date? Do I need to force my users to have the Month and Day (I can advise users to just use Jan or 1st if unknown)...
Thanks for any help!
Sorry, I realized I got this in the wrong forum....
I am still trying to figure this out and found the gmmktime function as follows:
http://www.w3schools.com/php/func_date_gmmktime.asp
gmmktime(hour,minute,second,month,day,year,is_dst)
... so in my example, would this work?
$date_of_visit = gmmktime(0,0,0,$mm,$dd,$yyyy);
