php mysql中意外的布尔值

Question

I know for a fact that the content of inputbox that I'm submitting exists in table1, yet this query:

$check = mysqli_query($con, "SELECT name FROM table1 WHERE name=$_POST[inputbox]");

var_dump($check);

is giving me a bool(false)

What am I doing wrong?

Answer 1

Maybe try:

$check = mysqli_query($con, "SELECT name FROM table1 WHERE name='".$_POST[inputbox]."'");
