Rookie Alert! Inserting data with php script question

[simpson_121919]

I have been trying to insert data into my database thru php script with no luck. I think its has to do with not being able access my database. My question is when I use MySQL command client and enter the password and get mysql> does that mean I can use that password to access my databases as long as  I point to the correct database with the mysqli_connect function. I dont think I fully understand how this works.  I have everything stored on my local computer and I use "localhost" in mysqli_connect function.

Honestly the best thing to start with is a little code. What do you have so far?

 

Here is a very very rough tutorial on how to do it..

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

mysql_query("INSERT INTO Persons (FirstName, LastName, Age)
VALUES ('Peter', 'Griffin', '35')");

mysql_query("INSERT INTO Persons (FirstName, LastName, Age)
VALUES ('Glenn', 'Quagmire', '33')");

mysql_close($con);
?>

Here is the code I have been using  -

 

<?php
  $first_name = $_POST['firstname'];
  $last_name = $_POST['lastname'];
  $when_it_happened = $_POST['whenithappened'];
  $how_long = $_POST['howlong'];
  $how_many = $_POST['howmany'];
  $alien_description = $_POST['aliendescription'];
  $what_they_did = $_POST['whattheydid'];
  $fang_spotted = $_POST['fangspotted'];
  $email = $_POST['email'];
  $other = $_POST['other'];

  $dbc = mysqli_connect('localhost', 'root', 'x', 'aliendatabase')
    or die('Error connecting to MySQL server.');

  $query = "INSERT INTO aliens_abduction (first_name, last_name, when_it_happened, how_long, " .
    "how_many, alien_description, what_they_did, fang_spotted, other, email) " .
    "VALUES ('$first_name', '$last_name', '$when_it_happened', '$how_long', '$how_many', " .
    "'$alien_description', '$what_they_did', '$fang_spotted', '$other', '$email')";

  $result = mysqli_query($dbc, $query)
    or die('Error querying database.');

  mysqli_close($dbc);

  echo 'Thanks for submitting the form.<br />';
  echo 'You were abducted ' . $when_it_happened;
  echo ' and were gone for ' . $how_long . '<br />';
  echo 'Number of aliens: ' . $how_many . '<br />';
  echo 'Describe them: ' . $alien_description . '<br />';
  echo 'The aliens did this: ' . $what_they_did . '<br />';
  echo 'Was Fang there? ' . $fang_spotted . '<br />';
  echo 'Other comments: ' . $other . '<br />';
  echo 'Your email address is ' . $email;
?>

 

I keep getting the die function read out 'Error querying database'

 

I'm wondering if Im using the right username. How do I check to make sure I have the right username.

Try this:  It doesn't fix anything, it only lets you know what the database thinks.

 

<?php
  $first_name = $_POST['firstname'];
  $last_name = $_POST['lastname'];
  $when_it_happened = $_POST['whenithappened'];
  $how_long = $_POST['howlong'];
  $how_many = $_POST['howmany'];
  $alien_description = $_POST['aliendescription'];
  $what_they_did = $_POST['whattheydid'];
  $fang_spotted = $_POST['fangspotted'];
  $email = $_POST['email'];
  $other = $_POST['other'];

  $dbc = mysqli_connect('localhost', 'root', 'x', 'aliendatabase')
    or die('Error connecting to MySQL server: <br />' . mysqli_connect_error());

  $query = "INSERT INTO aliens_abduction (first_name, last_name, when_it_happened, how_long, " .
    "how_many, alien_description, what_they_did, fang_spotted, other, email) " .
    "VALUES ('$first_name', '$last_name', '$when_it_happened', '$how_long', '$how_many', " .
    "'$alien_description', '$what_they_did', '$fang_spotted', '$other', '$email')";

  $result = mysqli_query($dbc, $query)
    or die('Error querying database: <br />' . mysqli_error($dbc));

mysqli_close($dbc);

  echo 'Thanks for submitting the form.<br />';
  echo 'You were abducted ' . $when_it_happened;
  echo ' and were gone for ' . $how_long . '<br />';
  echo 'Number of aliens: ' . $how_many . '<br />';
  echo 'Describe them: ' . $alien_description . '<br />';
  echo 'The aliens did this: ' . $what_they_did . '<br />';
  echo 'Was Fang there? ' . $fang_spotted . '<br />';
  echo 'Other comments: ' . $other . '<br />';
  echo 'Your email address is ' . $email;

?>
