[SOLVED] mysqli error...

[wondernate]

I am doing a tutorial from a book and I can't get it to work.  I have proofread the code over and over.  I am getting an error when trying to use the second function named emailChecker.    The first is just my DB connection and I blocked out the info for security...

 

 

Here is the error:

 

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VALUES ('[email protected]')' at line 2

 

 

Here is the code

 

Here is my PHP code that has the SQL in it.  Anyone see a prob?

 

<?php

 

//Function to connect to the database and test the connection

function doDB() {

global $mysqli;

 

// Establish a connection to the database

$mysqli = new mysqli("xxxxx", "xxxxx","xxxx","xxxxx");

 

// if connection fails, stop script execution

if (mysqli_connect_errno()){

printf("DATABASE CONNECTION FAILED: ", mysqli_connect_error());

 

}

 

}

 

function emailChecker ($email) {

global $mysqli, $check_res;

 

//check that email is not already in list

$check_sql = "SELECT id FROM subscribers WHERE email = '".$email."'";

$check_res = mysqli_query($mysqli, $check_sql)

or die(mysqli_error($mysqli));

}

 

?>

The query that is failing is probably an INSERT query, not the one that you posted (unless $email contains some SQL in it.)

Here is the code that is executing the function...  I put in an echo test and the email is in POST.  I tested the header function.  I tested the connection.  The problem seems to hit when I get to using the emailChecker function...

 

//trying to subscribe, validate email address

if ($_POST["email"] == "") {

header("Location: manage.php");

exit;

} else {

//connect to database

doDB();

 

//check that email is in list

emailChecker($_POST["email"]);

 

//get number of results and do action

  if (mysqli_num_rows($check_res) < 1) {

  // free result

  mysqli_free_result($check_res);

 

  //add record

  $add_sql = "INSERT INTO subscribers (email

VALUES ('".$_POST["email"]."')";

  $add_res = mysqli_query($mysqli, $add_sql)

  or die(mysqli_error($mysqli));

  $display_block = "<p>Thanks for Signing Up!</p>";

 

  //close connection to mysql

  mysqli_close($mysqli);

  } else {

  //print failure message

  $display_block = "<p> You are already subscribed!</p>";

  }

  }

}

How do you mark something as solved?
