Use bound parameter multiple times
(5 answers)
Closed 3 years ago.
I now already create a table called' factory. In his table, there are two columns which is Fac_ID (Primary Key, Varchar) and Fac_Name (Varchar). Let say if I want to add a new factory. E.g F09, then the Fac_ID and Fac_Name also insert with F09.
I just only key in F09 at Fac_Name and after I click button 'add', it will save F09 at Fac_ID and Fac_Name. Below is my current PHP code
<?php
//including the database connection file
include_once("config.php");
if(isset($_POST['Submit'])) {
$Fac_Name = $_POST['Fac_Name'];
$Fac_ID = $_POST['Fac_Name'];
// checking empty fields
if(empty($Fac_ID)) {
if(empty($Fac_ID)) {
echo "<font color='red'>Name field is empty.</font>
<br/>";
}
//link to the previous page
echo "<br/><a href='javascript:self.history.back();'>Go
Back</a>";
} else {
// if all the fields are filled (not empty)
//insert data to database
$sql = "INSERT INTO users(Fac_Name, Fac_ID) VALUES(:Fac_Name, :Fac_Name)";
$query = $conn->prepare($sql);
$query->bindparam(':Fac_Name', $Fac_Name);
$query->bindparam(':Fac_Name', $Fac_ID);
$query->execute();
//display success message
echo "<font color='green'>Data added successfully.";
echo "<br/><a href='index.php'>View Result</a>";
}
}
?>

You cannot use the same bind parameter twice, so would suggest to do the following:
$sql = "INSERT INTO users(Fac_Name, Fac_ID) VALUES(:Fac_Name, :Fac_Id)";
$query = $conn->prepare($sql);
$query->bindparam(':Fac_Name', $Fac_Name);
$query->bindparam(':Fac_Id', $Fac_ID);
$query->execute();
It also makes more sense as the variable you put in is also called $Fac_ID.
