PDO Inserting Data?

[glassfish]

This UPDATE script works:

$query = $pdo->prepare("UPDATE posts SET headline = ? WHERE id = ?");
    $query->bindValue("1", $_POST['headline']);
    $query->bindValue("2", "2");
    $query->execute();

Though, this INSERT script does not work:

$query = $pdo->prepare("INSERT INTO posts (headline, post) VALUES (?, ?)");
    $query->bindValue("1", $_POST['headline']);
    $query->bindValue("2", $_POST['post']);
    $query->execute();

Nothing gets added, when executing this script.

 

The connection:

<?php

$dsn = "mysql:dbname=phpblog;host=localhost";
$user = "root";
$password = "";
try{
    $pdo = new PDO($dsn, $user, $password);
}catch(PDOException $e){
    echo "Connection failed: " . $e->getMessage();
}

?>

Any suggestions why the INSERT script is not working?

Your insert doesn't reference the id column.  Is that column an auto-increment one?  Otherwise I think you need to specify all the columns when doing an insert.

i'm going to guess you don't have a column in your table named post and that the prepare() statement is failing with an error, assuming that emulated prepares are turned off, or the execute() statement is failing with an error, assuming that emulated prepared are not turned off (which unfortunately is the default.)

 

well written code is self-troubleshooting. it will tell you when, where, and why it is failing. to get your code to tell you when, where, and why it is failing, your code must have error checking logic in it.

 

you can either add conditional logic to test the result of each statement to find out if it is working or not or you can use exceptions. i recommend using exceptions for fatal problems.

Thanks for the responses.

 

I have had mispelled the column "post" into "posts" in MySQL.

 

After correcting the spelling mistake it is working now.
