how to use php date in mysql query

[Tinus]

Hi

I need to run a query based on a php date variable.

$add2days=strtotime(date("Ymd",$MyToday). "+2 day");
echo".....date(add2days)=".date('Y-m-d',$add2days)
 
$query2 = "SELECT `daydate` FROM publicholiday WHERE `daydate`=`date('Y-m-d',$add2days)`";
$aresult = $dbLink->query($query2);  
    //$resultrow = $aresult->fetch_row();
    //echo"sunday holiday row is".$resultrow[0];
    if($aresult)
     {.... }
 
 

if($aresult) is false when it should actually be true for the date I am sending

Thanks for the help!!

how do you know, that it *should* be true? actually, your query should either return noting or cause an error.

PS. the MySQL DATE() function expects only one parameter.

Hi

well, I have a mysql table in which all public holidays are stored.
A date is entered into an html form. Then my php tests if this day is a holiday.
In this specific section; it looks if the public holiday is on a sunday. If it is monday will be a holiday .

What I am actually asking is if the following will return a result or will it return an error, or empty result.

$query2 = "SELECT `daydate` FROM publicholiday WHERE `daydate`=`date('Y-m-d',$add2days)`"; 
$aresult = $dbLink->query($query2);   
 
 

The date is in the mysql table so if done correctly it should return a result.

that’s the part (in bold), that's not done correctly. thus you *should* get an error.

$query2 = "SELECT `daydate` FROM publicholiday WHERE `daydate`=`date('Y-m-d',$add2days)`";

Ok,thanks

How should I do it then ?

echo $_POST["inputdate"];
$indate=$_POST["inputdate"];
echo " indate is".$indate;
if (isset($_POST["inputdate"])){ 
$MyToday=date("Ymd");
$MyToday=strtotime($indate);}
else{
$MyToday=$today;}
 
if((date("D",$MyToday))=='Fri') 
   {
       $add2days=strtotime(date("Ymd",$MyToday). "+2 day");
    echo".....date(add2days)=".date('Y-m-d',$add2days);
   $query2 = "SELECT daydate FROM publicholiday WHERE daydate=date('Y-m-d',$add2days)";
   //(SELECT DATE_FORMAT( (SELECT DATE_ADD(`$Mytoday`,INTERVAL 2 DAY ) ) ,'%Y-%m-%d'))";
    $aresult = $dbLink->query($query2);  
    //$resultrow = $aresult->fetch_row();
    //echo"sunday holiday row is".$resultrow[0];
    if($aresult)
     { //Vrydag en vakansiedag val op sondag
       echo "public holiday on sunday so monday will be holiday";
       //doen f,s,s,m
       exec("C:/aptana/xampp-win32-1.7.3/xampp/htdocs/sas_prog >sas_prog.out");
       exec("Psexec.exe -i -d  sas.exe");   
        }

How should I do it then ?

for a start, by not putting PHP functions inside a string. (this only works in some special cases)

this would make way more sense:

$query2 = "SELECT `daydate` FROM `publicholiday` WHERE `daydate` = " . date('Y-m-d',$add2days);
