PHP - Oo Php Plus Oo Mysqli
Hello everyone,
For two weeks now, I'm trying to get this database connection in my query. Can someone give me a solution and tell me what I've done wrong? Am I overlooking something? <?php class Mysql{ public function connect(){ $mysqli = new mysqli('localhost','root','','login'); } } class Query extends Mysql{ public function runQuery(){ $this->result = parent::connect()->query("select bla bla from bla bla"); } } $query = new Query; $query->runQuery(); ?> Similar TutorialsWhen running the following code i get the error: Call to undefined method mysqli::errno() the code: $conn = new mysqli(HOST, USER, PASSWORD, DATABASE); if ($conn->errno() !== 0) { $msg = $conn->error(); throw new connErrorException($msg, 'Connect'); } I am fairly new to classes but as i understand it this should be correct. I am using mysql 5.1 so mysqli is on by default. I have even checked the php ini and everything looks fine there in respect to this. Any advice?
The below code produces a dropdown and when a selection is made and submitted produces ---------------------------------------------------------------------------
<!DOCTYPE><html><head>
<title>lookup menu</title>

<body><center><b>

I am using mysqli, OO, to connect to MySQL. I have only today started looking at this and am used to: Code: [Select] <?php $con = mysql_connect();//etc mysql_close($connection); ?> Am I right that with mysqli (OO) that I don't need to set a connection variable wither when connecting or closing?? Code: [Select] <?php mysqli::connect();//etc mysqli::close(); ?> What about with multiple databases, does mysqli keep track for me, as I am used to this: Code: [Select] <?php $con1 = mysql_connect();//db1 $con2 = mysql_connect();//db2 ?> //etc Ok I am trying to use mysqli instead of the usual mysql. Mysql would be outdated. With mysqli, sgl-injection is impossible if you use the "?" in those codes. I would normally use a function but I've made a simple script to find the error. I use $parameters and $sql because these are the data I need to give as parameters to the function, so I used it here too but without the function actually. Code: [Select] ini_set('display_errors',1); // 1 == aan , 0 == uit error_reporting(E_ALL | E_STRICT); # sql debug define('DEBUG_MODE',true); // true == aan, false == uit $userid = 11; $lang = 1; $newLink = "testing123"; $db_host = "localhost"; $db_gebruiker = "root"; $db_wachtwoord = ''; $db_naam = "projecteasywebsite"; $sql= "INSERT tbl_link(userid,linkcat,linksubid,linklang,linkactive,linktitle) VALUES(?, ?, ?, ?, ?, ?)"; $parameters = '"iiisis", $userid, 1, 0, $lang, 1, $newLink'; echo $parameters; $mysqli = new mysqli($db_host, $db_gebruiker, $db_wachtwoord, $db_naam); $stmt = $mysqli->prepare($sql); $stmt->bind_param($parameters); $stmt->execute(); echo "<br><br>". mysqli_connect_errno(); echo "<br><br>". mysqli_report(MYSQLI_REPORT_ERROR); $stmt->close(); $mysqli->close(); I got Wrong parameter count for mysqli_stmt::bind_param() So naturally a problem when we execute : Warning: mysqli_stmt::execute() [mysqli-stmt.execute]: (HY000/2031): No data supplied for parameters in prepared statement ($stmt->execute() Is someone using mysqli too ? hello , I'm starting to use mysqli and i have few questions. is there a guide for mysqli? and how do i use this functions at mysqli ? mysql_num_rows mysql_query mysql_fetch_assoc mysql_fetch_array thanks , Mor. I dont know whether the statement is correct.....i just tried it.....and it didn't work. $stmt->bind_param('ssiiiss',$_POST['name'],$_POST['email'],$_POST['d'],$_POST['m'],$_POST['y'],$_POST['add'],$_POST['phone']); here my first two values are strings and next 2 tiny int's next is int and last 2 again strings. Hi, The following code is what I want in that it creates a menu and I can select and display a table row.
I still need to use that selection to update the "lastused". I really appreciate your help. <!DOCTYPE><html><head><title>email menu</title></head> <body><center> <form name="form" method="post" action=""> <?php $con=mysqli_connect("localhost","root","cookie","homedb"); //============== check connection if(mysqli_errno($con)) {echo "Can't Connect to mySQL:".mysqli_connect_error();} else {echo "Connected to mySQL</br>";} //This creates the drop down box echo "<select name= 'target'>"; echo '<option value="">'.'--- Select email account ---'.'</option>'; $query = mysqli_query($con,"SELECT target FROM emailtbl"); $query_display = mysqli_query($con,"SELECT * FROM emailtbl"); while($row=mysqli_fetch_array($query)) {echo "<option value='". $row['target']."'>".$row['target'] .'</option>';} echo '</select>'; ?> <input type="submit" name="submit" value="Submit"/><!-- update "lastused" using selected "target"--> </form></body></html> <!DOCTYPE><html><head><title>email menu</title></head> <body><center> <?php $con=mysqli_connect("localhost","root","cookie","homedb"); if(mysqli_errno($con)) {echo "Can't Connect to mySQL:".mysqli_connect_error();} if(isset($_POST['target'])) { $name = $_POST['target']; $fetch="SELECT target,username,password,emailused,lastused, purpose, saved FROM emailtbl WHERE target = '".$name."'"; $result = mysqli_query($con,$fetch); if(!$result) {echo "Error:".(mysqli_error($con));} $lastused = "CURDATE()"; // update "lastused" using selected "target" //display the table echo '<table border="1">'.'<tr>'.'<td bgcolor="#ccffff align="center">'.

Edited by Tom8001, 30 November 2014 - 12:43 PM. Dear Sir/Madame I am making a website where user can insert data and wait for the admin to approve/reject the form. Now i am stuck with the update status where an admin can submit with a click pending to approval or reject with comments. I am new to PHP programming. Can somebody help me with the issue. Part 1 is inserting the data and part two is fetching the data but i am unable to solve the status approve/reject and comment at the same time on the view.php? page. Kindly help. Thank you.

Hi everyone, I wanted to some investigating before I label this as a bug, but from what I can see I'm not getting expected results. It appears as if mysqli_stmt_result_metadata does not return the proper object. It should be of mysqli_result type, but yet when I run mysqli_num_rows against it, I get 0, always. If I do a direct mysqli_query and take the resultset back, I can call mysqli_num_rows and it returns the proper value. Example #1(doesn't work): if($this->statement = mysqli_prepare($this->databaseConnection, "SELECT 1 FROM DIGIUSERS WHERE UNAME = ?")) { mysqli_stmt_bind_param($this->statement, 's', $username); mysqli_stmt_execute($this->statement); $this->errorQuery(); $result = mysqli_stmt_result_metadata($this->statement); //Ooops, the username is already taken! exit with status of -7 if(mysql_num_rows($result) > 0) { mysqli_rollback($this->databaseConnection); exit("<STATUS>-7</STATUS></USER>"); } mysqli_stmt_close($this->statement); } Example #2 (works but i cant bind variables): $result = mysqli_query($this->databaseConnection, "SELECT 1 FROM DIGIUSERS WHERE UNAME = $username"); $this->errorQuery(); //Ooops, the username is already taken! exit with status of -7 if(mysqli_num_rows($result) > 0) { mysqli_rollback($this->databaseConnection); exit("<STATUS>-7</STATUS></USER>"); } I have variable binding working just fine elsewhere on the site so I know it's not that. The only thing I can think of is that mysqli_stmt_result_metadata is not returning the proper object. For now i will use #2 but, very begrudgingly.... The following code is supposed to submit everything in the database on a table, Currently its doing the first row in the database. Not sure whats wrong.. function getNews(){ $query = $this->con->query("SELECT * FROM `". $this->prefix ."news`"); while ($result = $query->fetch_assoc()) { if($result['serveradded'] == 1){ $queryy = $this->con->query("SELECT * FROM `". $this->prefix ."news` WHERE serveradded=1"); while ($resultt = $queryy->fetch_assoc()) { return "<tr><td>The Advertisement ". ucfirst($resultt['name']) ." was created</td><td>". $resultt['date'] ."</td></tr>"; } } elseif($result['servupdate'] == 1){ $queryyy = $this->con->query("SELECT * FROM `". $this->prefix ."news` WHERE servupdate=1"); while ($resulttt = $queryyy->fetch_assoc()) { return "<tr><td>". $result['type'] ." ". ucfirst($resulttt['name']) ." was Updated by ". ucfirst($resulttt['updatedby']) ." </td><td>". $resulttt['date'] ." </td></tr>"; } } elseif($result['newuser'] == 1){ $queryyyy = $this->con->query("SELECT * FROM `". $this->prefix ."news` WHERE newuser=1"); while ($resultttt = $queryyyy->fetch_assoc()) { return "<tr><td>Account Created: ". ucfirst($resultttt['name']) ." was created</td><td>". $resultttt['date'] ."</td></tr>"; } } } } I have converted my mysql to mysqli and am working on converting some functions. My question - Can I not just convert the mysql to mysqli? This is the full code: Code: [Select] class zipcode_class { var $last_error = ""; // last error message set by this class var $last_time = 0; // last function execution time (debug info) var $units = _UNIT_MILES; // miles or kilometers var $decimals = 2; // decimal places for returned distance function get_zip_point($zip) { // This function pulls just the lattitude and longitude from the // database for a given zip code. $sql = "SELECT lat, lon from zip_code WHERE zip_code='$zip'"; $r = $mysqli->query($sql); if (!$r) { $this->last_error = mysql_error(); return false; } else { $row = mysql_fetch_array($r); mysql_free_result($r); return $row; } } function calculate_mileage($lat1, $lat2, $lon1, $lon2) { // used internally, this function actually performs that calculation to // determine the mileage between 2 points defined by lattitude and // longitude coordinates. This calculation is based on the code found // at http://www.cryptnet.net/fsp/zipdy/ // Convert lattitude/longitude (degrees) to radians for calculations $lat1 = deg2rad($lat1); $lon1 = deg2rad($lon1); $lat2 = deg2rad($lat2); $lon2 = deg2rad($lon2); // Find the deltas $delta_lat = $lat2 - $lat1; $delta_lon = $lon2 - $lon1; // Find the Great Circle distance $temp = pow(sin($delta_lat/2.0),2) + cos($lat1) * cos($lat2) * pow(sin($delta_lon/2.0),2); $distance = 3956 * 2 * atan2(sqrt($temp),sqrt(1-$temp)); return $distance; } function get_zips_in_range($zip, $range, $sort=1, $include_base) { // returns an array of the zip codes within $range of $zip.

I am brand new to the forum and I would like to ask a question regarding mysqli. I am not certain why the following code works: Code: [Select] ... $sqlCmd = "select * from usrdata"; $rs = $mysqli->query($sqlCmd); ... and the following code gives me a 500 internal error: Code: [Select] ... $sqlCmd = "select * from usrdata"; $result= dbQuery($sqlCmd); ... function dbQuery($sqlCmd){ $rt = array(); $rs = $mysqli->query($sqlCmd); while($row = $rs->fetch_assoc ()){ $rt[] = $row; } return 'records: ' . json_encode($rt); } The error occurs on the mysqli->query. Thanks for any help. Cheers! hi What is the correct way to do a function like: Code: [Select] public function check_($db, $skills) { $arr_tags = array('16', '17', '36', '546'); $z = implode(', ', array_fill(0, count($arr_tags), '?')); $str = implode('', array_fill(0, count($arr_tags),'s')); $par = "'" . implode("','", $arr_tags) . "'"; $c_arr_tags = count($arr_tag); $sql = $db -> prepare(" SELECT offer_id_offer FROM offer_has_tags WHERE tags_id_tags IN ($z) GROUP BY offer_id_offer HAVING COUNT(*) = ? "); $sql -> bind_param("$srt.'i'", $par, $c_arr_tags); $sql -> execute(); $sql -> bind_result($id_offer); return $id_offer; } At the moment i got: Number of elements in type definition string doesn't match number of bind variables I have some code I used to have in mysql and now im trying to convert to mysqli and I cant seem to find out what the problem is.

here is the error im getting:

I was pointed in this direction by a friend so firstly, hello
I'm having some teething problems (basically can't get my head around it) and wondered if anyone would be able to have a look at a script for me (beer money may be provided)
I'm currently using a php script which grabs information from a API with curl (JSON format). I'm limited to a number of requests an hour so my plan was to read the file, insert the data into a mysql table so that I could re-read over and over again with no limitations. Then use a script to run every few hours to grab the data.
The script I created works however it's a bit buggy with regards to what it does if information is already in the table. If there isn't a previous entry then it inserts everything fine.
The JSON data is a multi depth array, and deals with images as well as data so for me, it's rather complex.
What I want the script to do is this. Each item is a property (letting agent website)
Check to see if the property exists in the database and the JSON. If there is no record in the database, then insert in. If there is a record in the database, update that record. If there is a property in the database which isn't in the JSON file, then delete it from the database.
This is basically the same plan for each sub array (pictures, floorplans, etc) however the images are copied from the url given (hosted on amazon) to my own host in order to speed up loading times, etc.
i've added a copy of the code but obviously its going to be stupidly hard to understand.
Is there any way this could be split into different functions to try and sort it out? haha

Edited by Jam0r, 08 December 2014 - 10:51 AM. Hi,
I'm trying to write a better PHP code to create and manage my website.
I would like to start a MVC approach with PHP, using OOP. So I can manage the updates in a better way. For example, to begin my project, I would try with the shipping cost of our products, using a Class without merge the PHP and HTML code.
Something like this:
$shippingcost=new ShippingCost(); $shippingcost->state="Italy"; $shippingcost->get(); // here I have an array with cost, discount, time ecc.And If I need it in JSON, I write:
$shippingcost->get("JSON"); // here I have the JSON with cost, discount, time ecc.
I wrote the Class in this way:
class ShippingCost
{
public $state;
private $arrayReturned;
public function __construct() {
$this->stato="Italy"; // the default state
}
public function __destruct() {
}
public function get($format="array") {
$this->arrayReturned=array(
"cost" => 3.99,
"costDiscounted" => 7.99,
"discount" => "50%"
);
if (strtolower($formato)=="json") {
$this->arrayReturned=json_encode($this->arrayReturned);
}
return $this->arrayReturned;
}
}
It works well, but I need to get the values from a MySQL db. How can pass the MySQL connection to the Class? I'm not able to do this.
Thanks in advance and have a great 2015.
Rob.
