mySQL查询执行但不插入数据

I am trying to insert data into mySQL query from PHP code. The code executes without any error but does not insert the data into the database. What could be wrong? Thanks in advance.

    <?php 
    include 'dbc.php';
    $sql="INSERT INTO `realtorl_leads`.`data` (`LeadFirstName`, `LeadLastName`, `LeadEmail`, `LeadEmail2`, `LeadPhone`, `LeadCity`, `LeadAddress`, `LeadPostcode`, `LeadUserId`, `LeadLeadStatusId`, `LeadMonth`, `LeadAreas`, `LeadMinPrice`, `LeadMaxPrice`, `LeadMinBedrooms`, `LeadMaxBedrooms`, `LeadMinBathrooms`, `LeadMaxBathrooms`, `LeadMinYear`, `LeadNextFollowup_mm`, `LeadNextFollowup_dd`, `LeadNextFollowup`) VALUES ('Fahad', 'Uddin', 'fahad.fu@gmail,com', 'fahad@ff.com', '3242342', 'karachi', '3234asdasd.karachi', '74600', '222', '32432', '23', '232', '232', '23', '232', '323', '323', '232', '23232', '3232', '232', '23232')";
    ?>

EDIT:

I have the following code now, the executed code just shows a new line and text saying it does not work. Please guide.

<?php 
include 'dbc.php';
$LeadFirstName = $_POST['LeadFirstName'];
$LeadFirstName = $_POST['LeadFirstName'];
$LeadEmail =$_POST['LeadEmail'];
$LeadEmail2 =$_POST['LeadEmail2'];
$LeadPhone =$_POST['LeadPhone'];
$LeadCity =$_POST['LeadCity'];
$LeadAddress =$_POST['LeadAddress'];
$LeadPostcode =$_POST['LeadPostcode'];
$LeadUserId =$_POST['LeadUserId'];
$LeadLeadStatusId =$_POST['LeadLeadStatusId'];
$LeadMonth =$_POST['LeadMonth'];
$LeadAreas =$_POST['LeadAreas'];
$LeadMinPrice =$_POST['LeadMinPrice'];
$LeadMaxPrice =$_POST['LeadMaxPrice'];
$LeadMinBedrooms =$_POST['LeadMinBedrooms'];
$LeadMaxBedrooms =$_POST['LeadMaxBedrooms'];
$LeadMinBathrooms =$_POST['LeadMinBathrooms'];
$LeadMaxBathrooms =$_POST['LeadMaxBathrooms'];
$LeadMinYear =$_POST['LeadMinYear'];
$LeadNextFollowup_mm =$_POST['LeadNextFollowup_mm'];
$LeadNextFollowup_dd =$_POST['LeadNextFollowup_dd'];
$LeadNextFollowup =$_POST['LeadNextFollowup'];
$sql="INSERT INTO 'realtorl_leads'.`data (`LeadFirstName`, `LeadLastName`, `LeadEmail`, `LeadEmail2`, `LeadPhone`, `LeadCity`, `LeadAddress`, `LeadPostcode`, `LeadUserId`, `LeadLeadStatusId`, `LeadMonth`, `LeadAreas`, `LeadMinPrice`, `LeadMaxPrice`, `LeadMinBedrooms`, `LeadMaxBedrooms`, `LeadMinBathrooms`, `LeadMaxBathrooms`, `LeadMinYear`, `LeadNextFollowup_mm`, `LeadNextFollowup_dd`, `LeadNextFollowup`) VALUES ($LeadFirstName, $LeadLastName, $LeadEmail, $LeadEmail2, $LeadPhone, $LeadCity, $LeadAddress, $LeadPostcode, $LeadUserId, $LeadLeadStatusId, $LeadMonth, $LeadAreas, $LeadMinPrice, $LeadMaxPrice, $LeadMinBedrooms, $LeadMaxBedrooms, $LeadNextFollowup_mm, $LeadNextFollowup_dd, $LeadNextFollowup)";
$result = mysql_query($sql);
echo($result."<br>");
if (mysql_affected_rows($result)){
  echo("worked");
}else {
  echo("does not work");
}
?>

you will need to execute the query

include 'dbc.php';
$sql="INSERT INTO `realtorl_leads`.`data` (`LeadFirstName`, `LeadLastName`, `LeadEmail`, `LeadEmail2`, `LeadPhone`, `LeadCity`, `LeadAddress`, `LeadPostcode`, `LeadUserId`, `LeadLeadStatusId`, `LeadMonth`, `LeadAreas`, `LeadMinPrice`, `LeadMaxPrice`, `LeadMinBedrooms`, `LeadMaxBedrooms`, `LeadMinBathrooms`, `LeadMaxBathrooms`, `LeadMinYear`, `LeadNextFollowup_mm`, `LeadNextFollowup_dd`, `LeadNextFollowup`) VALUES ('Fahad', 'Uddin', 'fahad.fu@gmail,com', 'fahad@ff.com', '3242342', 'karachi', '3234asdasd.karachi', '74600', '222', '32432', '23', '232', '232', '23', '232', '323', '323', '232', '23232', '3232', '232', '23232')";
mysqli_query($con, $sql);
?>

Your code has a part missing, try:

include 'dbc.php';
$sql="INSERT INTO `realtorl_leads`.`data` (`LeadFirstName`, `LeadLastName`, `LeadEmail`, `LeadEmail2`, `LeadPhone`, `LeadCity`, `LeadAddress`, `LeadPostcode`, `LeadUserId`, `LeadLeadStatusId`, `LeadMonth`, `LeadAreas`, `LeadMinPrice`, `LeadMaxPrice`, `LeadMinBedrooms`, `LeadMaxBedrooms`, `LeadMinBathrooms`, `LeadMaxBathrooms`, `LeadMinYear`, `LeadNextFollowup_mm`, `LeadNextFollowup_dd`, `LeadNextFollowup`) VALUES ('Fahad', 'Uddin', 'fahad.fu@gmail,com', 'fahad@ff.com', '3242342', 'karachi', '3234asdasd.karachi', '74600', '222', '32432', '23', '232', '232', '23', '232', '323', '323', '232', '23232', '3232', '232', '23232')";
$result = mysql_query($sql);

use $result to check whether your command is executing successfully, to do this try:

if (mysql_num_rows($result)){
  //echo successfull execution message
}else {

  //echo error message, it could be "information is not added"
}

though mysql is depreciated but it still works for me.
