Question

if(isset($_POST["request"])){
$email = $_POST['email'];
$p_name = $_POST['p_name'];
$noc = $_POST['noc'];
$year = $_POST['year'];
$get_email = "select email from book where email = '$email' ";
$run_email = mysqli_query($con,$get_email);
$check = mysqli_num_rows($run_email);
if($check==1){
echo "<script>alert('You Have Already Booked') </script>";
exit();
}
$get_name = "SELECT capacity from party where type_party='$p_name' ";
$run_name = mysqli_query($con,$get_name);
$checkk = $run_name > '$noc';
if(checkk){
echo "<script>alert('Out Of Bound') </script>";
exit();

How to Compare capacity from party table with that the value of $noc??
Please help me out. Thank You!

Answer 1

You have missed the $ in last condition.
<?php
$email = $_POST['email'];
$p_name = $_POST['p_name'];
$noc = $_POST['noc'];
$year = $_POST['year'];
$get_email = "select email from book where email = '$email' ";
$run_email = mysqli_query($con,$get_email);
$check = mysqli_num_rows($run_email);
if($check==1){
echo "<script>alert('You Have Already Booked') </script>";
exit();
}
$get_name = "SELECT capacity from party where type_party='$p_name' ";
$run_name = mysqli_query($con,$get_name);
$checkname = mysqli_num_rows($run_name );
//$checkk = $run_name > '$noc';
if($checkname > $noc){
echo "<script>alert('Out Of Bound') </script>";
exit();
}
?>

Just change you code like below.
$get_name = "SELECT capacity from party where type_party='$p_name' ";
$run_name = mysqli_query($con,$get_name);
$row_cnt = mysqli_num_rows($run_name);
$rows = mysqli_fetch_assoc($run_name );
// please use any one condition which meet your requirement.
$checkk = $run_name > $noc;
// or
$checkk = $rows['capacity'] > $noc;
// if it's not working try below
$checkk = $rows[0]['capacity'] > $noc;
if($checkk){
echo "<script>alert('Out Of Bound') </script>";
exit();
}
I get the number of results found from the query using "mysqli_num_rows" and then compare with $noc for proper result. Or else use the second condition to compare $noc with "$run_name['capacity']".
