good day;
please spare some of your precious time with me,
i'm really having a hard time to analyze this.

my problem is how to evaluate two dates if it is not the same date.
the first date is the actualdate

$actualTime = date ('d M Y @ H:i:s', $time+28800);

the second date is from database "SELECT `date` FROM `medicalrecords` where date=`$actualTime`" therefore if query_row == 1,the condition would be true.
but my query seems not working.
note that datatype of medicalrecords.date is varchar.

sorry if I sound stupid to you im new in php.

$secs_add = 28000;
 list($year,$month) = explode("-",date('Y-n', time() + $secs_add));
 $r = mysql_query("SELECT ... FROM ... WHERE MONTH(`date`) = $month AND YEAR(`date`) = $year"); 
 ...

however, this assumes your mysql date format is readable, e.g. 2012-01-18...

The only formats that I can think of that should be used are the above: yyyy-mm-dd and unix timestamp (integer), or even yyyymmdd. You can easily reformat unix timestamp s and yearmonthday integers to the standard yyyy-mm-dd.

but im having this is my mind..

$crow = mysql_num_rows($r);
if ($crow == 1) {
echo 'cant add records with same date';
}

I have a question sir, what is that MONTH and YEAR in your WHERE condition?

ayayay sorry sir i was giving u the wrong information, the format of date in mysql is 20 Jan 2012
is there also a DAY function sir?

because my goal is to prevent the user for a day to enter a record if 4 of values is already existing in the specified fields (one of this is the date field)

This date format IMO should not be used as the recordset cannot be ordered and date functions such as DAY and MONTH will not work with it. Yes there is also a day function. If you are using mysql you really should try reading the online manual.

problem solve: thank you sir ardav i wish i could send u a beer..
heres what I did..

$comTime = date ('d M Y', $time+28800);
$queryeval = "SELECT `admissionId` FROM `medicalrecords` WHERE `studentsId`='$patient' AND                                           `diagnosisId`='$diagnosis' AND `date` LIKE '$comTime%'"; 
$queryeval_run = mysql_query($queryeval);
$num_rows = mysql_num_rows($queryeval_run);
							
if ($num_rows == 1) {
$comTime = date ('d M Y', $time+28800);
echo '<br><strong><font color="red" size="1px">'.$row_rsStudentsId['studentsLastName'].", ".$row_rsStudentsId['studentsFirstName']." ". '<br>is already checkup today<br>with the same diagnostic</font></strong>';	
}

sir I have a question again, is there a except function in where condition?
