I was trying insert values simultaneously into MySql database using mysqli_multi_query but record insertion failed…
Below is my php code with db
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE)
{
$sql= "INSERT into inverterlog (`id`,`timestamp`,`irradiance`,`ambienttemp`,`photovoltaictemp`,`pv1voltage`,`pv2voltage`,`pv3voltage`,`pv1current`,`pv2current`,`pv3current`,`pv1power`,`pv2power`,`pv3power`,`pv1energy`,`pv2energy`,`pv3energy`,`gridvoltagegv1`,`gridvoltagegv2`,`gridvoltagegv3`,`gridcurrentgc1`,`gridcurrentgc2`,`gridcurrentgc3`,`gridpowergp1`,`gridpowergp2`,`gridpowergp3`,`sumofapparentpower`,`gridpowertotal`,`gridenergyge1`,`gridenergyge2`,`gridenergyge3`,`socounter`,`gridcurrentdcgc1`,`gridcurrentdcgc2`,`gridcurrentdcgc3`,`gridresidualcurrent`,`gridfrequencymean`,`dcbusupper`,`dcbuslower`,`temppower`,`tempaux`,`tempctrl`,`temppower1`,`temppowerboost`,`apparentpowerap1`,`apparentpowerap2`,`apparentpowerap3`,`sovalue`,`reactivepowerrp1`,`reactivepowerrp2`,`reactivepowerrp3`,`opmode`,`latestevent`,`pla`,`reactivepowermode`,`overexcitedunderexcited`,`reactivepowerabs`,`inverter`)

$sql.= "INSERT into data (`id`,`timestamp`,`gridpowertotal`,`inverter`) values ('','$newDate','$emapData[26]','$inverter')";
//we// are using mysql_query function. it returns a resource on true else False on error
$result = mysqli_multi_query( $con,$sql);
if(! $result )
{

</script>";
}
}
}
fclose($file);
}
//throws a message if data successfully imported to mysql database from excel file
echo "<script type=\"text/javascript\">

window.location = \"four.php\"
/</script>";
//close of connection
mysqli_close($con);
}
}
