  1. Hello all, I resolved the problem, FINALLY.. there were multiple errors. For starters the user name was not root.....The suggestions got me searching for the right parameters, and finally resolved my problem. YEAH. Thank you, Jaloney
  2. Hello, I changed root to drupal user as my config file for sql has this: [client] port=3306 user=drupaluser [mysql] [mysqladmin] user=root port=3306 So now I get this error: Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in C:\Users\Owner\Sites\acquia-drupal\CO241\my_script.php on line 11 Perplexed.

  3. Hello My instructor routinely gives assignments where the code doesn't work and we have to fend for ourselves to figure out what the issue is. My assignment is to enter this code and connect to Acquia Drupal database. i keep getting an error referring to link 1 where the database connect statement is given. The database doesn't have a password. I did enter the code in Phpmy admin before I tried to upload it to the Acqui-Drupal desktop to find the error in line one. This is the code. He doesn't use the same syntax as the book which makes learning harder. Any idea what is wrong with the database connect statement? I did try adding my user name and password in the connect mysqli_connect statement but it did not help. <?PHP //book page 268 $dbc=mysqli_connect("localhost","root",""); mysqli_select_db($dbc,"acquia_drupal"); $query="select name from role"; $r=mysqli_query($dbc,$query); while($row=mysqli_fetch_array($r)) { echo $row['name']."<br />"; } mysqli_close($dbc); ?>
  4. Larry, Thank you so much. The instructors code has character set in two places and it wouldn't work in PHP myadmin. I deleted these and I am good to go. Finally!
  5. Okay I found the SQL commands nestled in the middle of the file. I copied and pasted into my PHP Myadmin SQL command prompt and I get an error on line one. #1064 - 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 'CHARSET utf8' at line 1 I looked at the code and it is exactly the same as yours and the books. All of the other SQL commands for other chapters work fine. I was hoping your command files were different as My instructor tried to figure out why this same error is happening with the file he provided to the class.. which gives the same error. He gave up and I can't give up as I need to learn this stuff and I can't learn it without a way to do the searches with the database.
  6. It is actually Chapter 6. I have two of your books and in one of them it was in a different chapter. The forums database that is used for the Chapter SIX tutorials on Database design, and primary key's ect .. there is no sql commands to fill it with data if I create the database..
  7. There is one folder titled SQL commands in the downloads for this book and it is for an author's table..Where are the SQL commands for the Forums database in Chapter 5. All of the tutorials in that chapter are based on that database, so I would appreciate a link to the SQL file as I do not find it on downloads page.
  8. Hi In the downloads for Chapter this book, Chapter Five is missing. I need the Forums scripts. Thank you
  9. Hello, I am trying to follow along in the book. I am on page 135 number 2. "Insert One row of data into the users table WITHOUT naming the columns.Because I chose to use PHPmyadmin, I don't see how to do this. There is no example in the book. My instructor emailed me and said to use SQL Tab with Insert.. When I do this, I see the names of the columns in there.. Do I delete these? Not sure how to do this excersize with PHPmyadmin
  10. HARTLEYSAN OMG Thank you. How is it that after a while the more you look at your code, the less you see? I printed the code out, compared it with the text.. and did not see a thing! Any ideas on how to get around this? THANK YOU! THANK YOU! THANK YOU! My day is 100 percent better now. Jaloney
  11. I am having problems with the same script. This is the error that is making me get the error message on my form: I am blue in the face and getting so frustrated as I just can't see what the problem is. Notice: Undefined variable: POST in C:\Users\Owner\Sites\acquia-drupal\CO241\calculator.php on line 12 I keep getting the error on last line of IF statement && is_numeric($POST['efficiency']) ) { Any ideas appreciated. <?php # Script 3.5 - calculator.php $page_title = 'Trip Cost Calculator'; include ('includes/header.html'); // Check for form submission; if($_SERVER['REQUEST_METHOD'] == 'POST') { //Minimal form validation if (isset($_POST['distance'], $_POST['gallon_price'], $_POST['efficiency']) && is_numeric($_POST['distance']) && is_numeric($_POST['gallon_price']) && is_numeric($POST['efficiency']) ) { //Calculate the results: $gallons = $_POST['distance'] / $_POST['efficiency']; $dollars = $gallons * $_POST['gallon_price']; $hours = $_POST['distance']/ 65; //Print the results: echo '<h1>Total Estimated Costs</h1> <p>The total cost of driving ' . $_POST['distance'] .
