What I am trying to achieve is count the total number of vehicles in the "vehicles" db table and pass it to views (I have recently moved over to MVC so still learning so please be kind and keep it simple for me please) I have a folder in views called "vehicletracker" , within this folder I have 2 files "index.php" and "widget.php".........The "widget.php" file is an "include" within "index php". The problem I am having is passing data from the controller to the view, I keep getting an "Undefined index: total" error and wonder if someone can help and show me where I am going wrong. This is my Model
<?php class Widget { private $db; public function __construct(){ $this->db = new Database; } public function countVehicles(){ $this->db->query("SELECT * FROM vehicles"); return $this->db->rowCount(); } } This is my controller
<?php class Widgets extends Controller{ public function __construct(){ $this->widgetModel = $this->model('Widget'); public function widget (){ $data['total'] = $this->widgetModel->countVehicles(); $this->view('vehicletracker/widget', $data); } } And my view

Thanks in advance... S Hi there,
I'm new to all this so I've been following instructions from various sites and books. So far I have installed Apache, PHP and mysql, however when I browse to localhost/test.php (created to view phpinfo() through the browser) i can't see mysql or mysqli only the mysqlnd.
Here is an overview of software I've installed, OS and things I've added so far;
OS ver Windows7 Professional 32-bit VM This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=314265.0 I have a form that submits a record and saves it to the database, I've got that working already, I'm trying to figure out if there is a cleaner way to delete a record with a button that gets a value from the unique key, in this case 'id' here is how the delete button looks like: // get info from table $query = "SELECT id, Title, Message FROM table_name"; $result = mysql_query($query); //displaying all data while($row = mysql_fetch_assoc($result)) { echo" <div class='status'><h3>{$row['Title']} <br></h3>" . " <h5>{$row['Message']} <br><br></h5>"; $id = $row['id']; //trying to get unique key from database //delete button echo "</div> <form action='delete.php' method='post' /> <input type='hidden' name='delete' value='yes' /> <input type='hidden' name='id' value='$id' /> <input type='submit' value='remove' /></form>"; } As you can see, i'm trying to give $id a unique value but for some reason i'm not getting it. The delete.php code looks like this: if (isset($_POST['delete']))// check if delete was clicked { $query = "DELETE FROM table_name WHERE id='$id'"; echo "$id Deleted successfully"; } elseif(!mysql_query($query, $db_server)) { echo "DELETE failed: $query<br />" . myql_error() . "<br /><br />"; } mysql_close(); I'm new to php and still learning so, if you think there are other ways to do this, please let me know, the button won't do anything to the data. Thanks in advance Hi all: I have been going nuts trying to get this to work. I have gone through many attempts based on internet searches and examples that simply do not work. I have files stored in my MySQL db. The files cna be of any type and are being displayed in a listed report. The files are hyperlinked and clickable, but here is the issue: When I click on a file in: http://development.products-and-services.ca/cms/test.php I get: http://development.products-and-services.ca/cms/test2.php?content=DHall_CV_webdev_eng.pdf as a blank page result. The objective is to get a file download alert or to see the file in the browser. Any ideas? Hello to all, I have problem figuring out how to properly display data fetched from MySQL database in a HTML table. In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table. The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'
Can someone help me on this, I guess the problem lies in the while loop? <thead> <tr> <th data-column-id="id" data-type="numeric">ID</th> <th data-column-id="email">Subscriber's Email</th> <th data-column-id="validity">Validity</th> <th data-column-id="valid_from">Valid From</th> <th data-column-id="valid_to">Valid To</th> </tr> </thead> Here is part of the PHP code:
<?php while($row = $stmt->fetch(PDO::FETCH_ASSOC)) { echo ' <tr> <td>'.$row["id"].'</td> '; while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) { echo ' <td>'.$row1["email"].'</td> '; } if($row["validity"] == 1) { echo '<td>'.$row["validity"].' month</td>'; }else{ echo '<td>'.$row["validity"].' months</td>'; } echo ' <td>'.$row["valid_from"].'</td> <td>'.$row["valid_to"].'</td> </tr>'; } ?>
Thank you. This could be PHP or MySql so putting it in PHP forum for now... I have code below (last code listed) which processes a dynamically created Form which could have anywhere from 0 to 6 fields. So I clean all fields whether they were posted or not and then I update the mySQL table. The problem with this code below is that if, say, $cextra was not posted (i.e. it wasnt on the dynamically created form), then this code would enter a blank into the table for $cextra (i.e. if there was already a value in the table for $cextra, it gets overwritten, which is bad). What is the best way to handle this? I'm thinking i have to break my SQL query into a bunch of if/else statements like this... Code: [Select] $sql = "UPDATE cluesanswers SET "; if (isset($_POST['ctext'])){ echo "ctext='$ctext',"; } else { //do nothing } and so on 5 more times.... That seems horribly hackish/inefficient. Is there a better way? Code: [Select] if (isset($_POST['hidden']) && $_POST['hidden'] == "edit") { $cimage=trim(mysql_prep($_POST['cimage'])); $ctext=trim(mysql_prep($_POST['ctext'])); $cextra=trim(mysql_prep($_POST['cextra'])); $atext=trim(mysql_prep($_POST['atext'])); $aextra=trim(mysql_prep($_POST['aextra'])); $aimage=trim(mysql_prep($_POST['aimage'])); //update the answer edits $sql = "UPDATE cluesanswers SET ctext='$ctext', cextra='$cextra', cimage='$cimage', atext='$atext', aextra='$aextra', aimage='$aimage'"; $result = mysql_query($sql, $connection); if (!$result) { die("Database query failed: " . mysql_error()); } else { } hi guys, im new to this forum I'm new also to php, I need help from you guys: I want to display personal information from a certain person (the data is on the mysql database) using his name as a link: example: (index.php) names 1. Bill Gates 2. Mr. nice Guy i want to click Bill Gates (output.php) Name: Bill Gates Country:xxxx Age: xx etc. How can i make this or how to learn this? Hi I am trying to select and order data/numbers from a colum in a mysql data base however i run the code and it returns no value just a blank page no errors or any thing so i think the code is working right but then it returns no result? Please help thanks Here is the code: <?php $host= "XXXXXX"; $mysql_user = "XXXXXX"; $mysql_password = "XXXXXX"; $mysql_database = "XXXXXXX"; $connection = mysql_connect("$host","$mysql_user","$mysql_password") or die ("Unable to connect to MySQL server."); mysql_select_db($mysql_database) or die ("Unable to select requested database."); $row = mysql_fetch_assoc( mysql_query( "SELECT XP FROM Game ORDER BY number DESC LIMIT 1" ) ); $number = mysql_result(mysql_query("SELECT XP FROM Game ORDER BY number DESC LIMIT 1"), 0); echo "The the highest XP is $number"; ?> I have a form on our website that a user can fill out for custom product. I want the form data to be 1) stored into a mysql database AND after storing said data, 2) email the same data to our sales department. 1) The form data DOES get stored into mysql database (except for the first two fields, for some weird reason) 2) I added a "mail" section to the php file that stores the data into the database, but it is not working correctly. I have stripped the email portion down to sending just one of the fields in the "message" to make it easier for troubleshooting I have included here, both the form section of the html file, and the formdata.php file that processes the data for your analysis. I am relatively new to php so there are going to be some issues with security, but I can work on those after I get the store & email process to work correctly. Please review my code and see if anyone can be of assistance. I looked through the forums and couldn't find another issue that was the same as mine. If I just overlooked, please tell me the thread post #.

Currently its sorted by ID. But I want to add option that admin can sort data (click on up/down link or whatever). Its about forum script and all forums have categories. Forum and categories are in same table. Forum "parent" is ID of category. So i have following sorting: Cat1 [ID1] ->Forum1 [ID2] [PARENT1] ->Forum2 [ID3] [PARENT1] Cat2 [ID4] ->Forum3 [ID5] [PARENT2] ->Forum4 [ID6] [PARENT2] I need to add additional field "sort". On click admin can UPDATE sorting by increasing/decreasing number. But problem is categories and forum are in same table. If I want to move up FORUM1 (ID2) with (for example) "sort" number 2 I must decrease number (-1) and that forum will be with same sort number as category above. Also if I want to move Category up/down it also must move all forums from that category (but that is not big problem). What is best way to solve this? So i pull some records out of a mysql table and i want to display them in 5 even columns. I'm not entirely sure how to do the math & logic to accomplish this. The pull is simple $qry = "SELECT DIST_PART_NUM FROM $tablename"; $sql = mysql_query($qry) or die(mysql_error()); while($res = mysql_fetch_assoc($sql)) { // CREATE 5 even columns here. } so let's say i just retrieved 5,000 part numbers, i'd like to display then in a table of 5 columns with 1000 records per column. This is easy math, but i need the script to automatically figure out the #'s. Also the tricky part is that i dont want to display the part numbers like so 11111 22222 33333 44444 55555 66666 77777 88888 99999 00000 but rather 11111 44444 77777 22222 55555 88888 33333 66666 99999 00000 the remainder if there is one can go in the last column or whatever is easier. I'd tried googling this, but it's not easy to phrase what i'm looking for. Thanks for the help. PS: I'm not looking to copy and paste code, if possible please explain your way so that i can learn the logic. Hi guys, I have an array: array ( [apple]=> red, [orange] => orange, [banana] => yellow ) That I want to insert into the apidata table, the PDO connection is good so I guess my code is wrong: $mykeys = implode(', ', array_keys($newarr)); $myplaceholders[] = '(' . implode (", ", array_fill(0, count($newarr), '?')) . ')'; $values = array_values($newarr); $res = $db->prepare("INSERT INTO apidata (item, value) VALUES $myplaceholders") ; $res->execute([$mykeys, $values]); The apidata table has three fields id (auto_increment) item and value, where am I going wrong?
