All is in the title. why I only get the first line of my table and not all the fields.
Function :
class Services_Label extends Services_Abstract
{
public function getlibelle()
{
$sRequest = 'SELECT NAME FROM menu WHERE id_application = 2';
$this->executeQueries($sRequest);
$aResult = $this->getOneResult();
$this->freeStatement();
return $aResult;
}
}
function application :
$oMessage = new Services_Label();
$toto = $oMessage->getlibelle();
var_dump($toto);
answer :
string(15) "Prise en charge"
table :
Going by the name of the getOneResult(), your resultset is probably being limited to one result.
Can you post the whole function to confirm?
I have no idea from your question what your table columns are called, but if you want all of the columns use SELECT *
class Services_Label extends Services_Abstract
{
public function getlibelle()
{
$sRequest = 'SELECT * FROM menu WHERE id_application = 2';
$this->executeQueries($sRequest);
$aResult = $this->getOneResult();
$this->freeStatement();
return $aResult;
}
}
It is most often better to actually name only the columns you actually want returned so you would do that like this
class Services_Label extends Services_Abstract
{
public function getlibelle()
{
$sRequest = 'SELECT NAME,COL2,COL3 FROM menu WHERE id_application = 2';
$this->executeQueries($sRequest);
$aResult = $this->getOneResult();
$this->freeStatement();
return $aResult;
}
}
this is the function getoneresult()
public function getOneResult()
{
$row = $this->getNextRow(OCI_BOTH | OCI_RETURN_NULLS);
if (is_array($row)) {
return $row[0];
} else {
return false;
}
}
You need to collect the rows using a while loop. So change your function 'getOneResult' to something like this.
public function getResults()
{
$array = array();
while ($row = $this->getNextRow(OCI_BOTH | OCI_RETURN_NULLS)) {
$array[] = $row;
}
return $array;
}

This is my query counting rows in tblapplication
public function countallrecord() {
$query = $this->db->get('tblapplication');
return $query->num_rows();
}
and this is the function to get all the data
public function getdata() {
$query = $this->db->get('tblapplication');
return $query->result();
}
Is there any way I can make this code on one function
I'm trying to pass it here:
public function Countandviewallrecord() {
// returns both rows and count
}
Just return it as an array. Include the results and count in their respective indices:
public function get_records()
{
$result = $this->db->get('tblapplication');
$data['results'] = $result->result();
$data['count'] = $result->num_rows;
return $data;
}
When accessing the model method in your controller, the usual:
$data = $this->model_name->get_records();
echo $data['count']; // whatever number this is
if($data['count'] > 0) {
foreach($data['results'] as $row) {
echo $row->column_name; // etc blah blah ..
}
}
this Countandviewallrecord will display data as well count total records
public function Countandviewallrecord(){
$TotalRecords= $this->countallrecord();
$totalData= $this->getdata();
}
So i have this class for loading data from my MySQL database :
class Db {
protected static $connection;
public function connect() {
if(!isset(static::$connection)) {
$config = parse_ini_file('config.ini');
static::$connection = new mysqli('localhost',$config['username'],$config['password'],$config['dbname']);
}
if(static::$connection === false) {
return false;
}
return static::$connection;
}
public function query($query) {
return $this->connect()->query($query);
}
public function select($query) {
$rows = array();
$result = $this->query($query);
if($result === false) {
return false;
}
while ($row = $result->fetch_assoc()) {
$rows[] = $row;
}
return $rows;
}
public function error() {
return $this->connect()->error;
}
public function quote($value) {
return "'" . $this->connect()->real_escape_string($value) . "'";
}
}
I use that class like this :
$db = new Db();
$rows = $db -> select("SELECT name, shortlink FROM `test` WHERE id=3");
It gives me an array with the data.
The problem is that i want to pull out specific data, for example the shortlink field.
How do i do that? I have tried echo $rows['shortlink'], but that gives me the following error :
Undefined index: shortlink
So how do I print specific data?
Your returned $rows columns is an array of associative arrays, to pull out shortlink data returned from the query you have to do something like this:
foreach($rows as $row) {
echo $row['shortlink'];
}
I know it has already been asked, but I'm not able to solve this. Below is my control module
public function ahome()
{
$this->load->model('model');
$data['user'] = $this->model->selall('user');
$this->load->view('ahome', $data);
if ($this->input->post('del'))
{
$did = $this->input->post('chk');
// print_r($did);
for ($i = 0; $i < count($did); $i++)
{
$multi = $did[$i];
print_r($multi);
$this->model->delall("user", $multi);
// redirect("control/ahome");
}
}
}
and this is my model module
public function delall($tb,$wh)
{
$this->db->query("delete from $tb where uid in('$wh')");
}
now problem is that it's only delete single row not multiple rows
In your query string, try removing the quotes around the $wh variable.
public function delall($tb,$wh)
{
$this->db->query("delete from $tb where uid in ($wh)");
}
That should get it to work; however, you should be using CodeIgniter's query bindings. Something like this:
public function delall($tb,$wh)
{
$this->db->query("delete from $tb where uid in (?)", array($wh));
}
Refer to this answer for more details.
Try this,
controller,
public function ahome()
{
$this->load->model('model');
$data['user'] = $this->model->selall('user');
$this->load->view('ahome', $data);
if ($this->input->post('del'))
{
$did = $this->input->post('chk');
// print_r($did);
foreach ($did as $d_id)
{
$this->model->delall("user", $d_id);
// redirect("control/ahome");
}
}
}
Model:
public function delall($tb,$wh)
{
$this->db->where('id',$wh);
$this->db->delete($tb);
return true;
}
I want to retrieve data from a table in database and display the result in an array in the form below.
array("1"=>"Value 1", "2"=>"value2")
Here is the function I tried using but I get error when I try to display the array. Please I need help on this. I'm new to OO Php.
<?php
class query {
public function listfields (){
$result = $this->mysqli->query("SELECT id, name FROM fields", MYSQLI_USE_RESULT);
while($row=$result->fetch_assoc()){
$this->fields[$row["id"]] = $row["name"];
}
$result->free();
}
public function fields(){
return $this->fields;
}
}
$list = new query;
$list->listfields();
$field1 = $list->fields();
echo $field1;
?>
Instead of your function fields, you will need a property fields, which you can access.
Furthermore i suggest using getters and setters instead of a public property, im sure you will find out how.
This will return the Data in form array("1"=>"Value 1", "2"=>"value2").
class query {
public $fields;
public function fillfields ()
{
$result = $this->mysqli->query("SELECT id, name FROM fields", MYSQLI_USE_RESULT);
while($row=$result->fetch_assoc()){
$this->fields[] = $row["name"];
}
$result->free();
}
$list = new query;
$list->fillfields();
$field1 = $list->fields[1];
echo $field1;
Try This.
<?php
class query {
public function listfields (){
$fields = array();
$rowcnt =1;
$result = $this->mysqli->query("SELECT id, name FROM fields", MYSQLI_USE_RESULT);
while($row=$result->fetch_assoc()){
$this->fields[$row["id"]] = $row["name"];
//$this->fields[$rowcnt] = $row["name"]; // if you want different indexing.
$rowcnt++;
}
$result->free();
}
public function fields(){
return $this->fields;
}
}
$list = new query();
$list->listfields();
$field1 = $list->fields();
var_dump($field1);
?>
I can do this when selecting a single row fine but cant quite get my head around doing this for multiple rows of data.
For the single row I simply instantiate a new object that does a number of operations behind the scenes that bascially produces a row from the database as our object.
Example:
$object = new Classname($param);
foreach($object->row as $key=>$value) {
echo $key.":".$value."\n";
}
//output
id:1
firstname:steve
lastname:took
etc...
Any clever people here able to point me in the right direction please?
NOTE: just want to be able to create an object for each row rather than the one object with nested arrays
EDIT: sorry $object->row is a member of the class that stores selected row from the database
If I got you the answer is pretty simple mysql_fetch_object
Example:
while ($row = mysql_fetch_object($result)) {
echo $row->user_id;
echo $row->fullname;
}
Why don't you consider to use an ORM (Object Relational Mapper), like Doctrine or Propel?
I prefer Doctrine: http://www.doctrine-project.org/
Enjoy! :)
Here is an example
class users extends db {
public $users_id = 0;
public $users_group = 0;
public $users_firstname = 0;
public $users_lastname = 0;
public function open($id) {
if (is_numeric($id)) {
$sql = "SELECT * FROM users WHERE users_id = '$id'";
$res = parent::DB_SELECT($sql);
if (mysql_num_rows($res) <> 1) {
return 0;
}
} else {
$sql = "SELECT * FROM users " . $id;
$res = parent::DB_SELECT($sql);
if (mysql_num_rows($res) <= 0) {
return 0;
}
}
$data = array();
while ($row = mysql_fetch_array($res)) {
$this->users_id = $row['users_id'];
$this->users_group = $row['users_group'];
$this->users_firstname = $row['users_firstname'];
$this->users_lastname = $row['users_lastname'];
$data[] = (array) $this;
}
return $data;
}
public function setUsersId($users_id) { $this->users_id = addslashes($users_id); }
public function getUsersId() { return stripslashes($this->users_id); }
public function setUsersGroup($users_group) { $this->users_group = addslashes($users_group); }
public function getUsersGroup() { return stripslashes($this->users_group); }
public function setUsersFirstname($users_firstname) { $this->users_firstname = addslashes($users_firstname); }
public function getUsersFirstname() { return stripslashes($this->users_firstname); }
public function setUsersLastname($users_lastname) { $this->users_lastname = addslashes($users_lastname); }
public function getUsersLastname() { return stripslashes($this->users_lastname); }
}
You could use MySQLi.
// Connect
$db = new mysqli('host', 'user', 'password', 'db');
// Query
$users = $db->query('SELECT * from users');
// Loop
while($user = $users->fetch_object()) {
echo $users->field;
}
// Close
$users->close();
$db->close();
