I have a added custom function to the system->libraries->Form_validation.php
public function serial_exist($str, $value)
{
list($table, $column) = explode('.', $value, 2);
$query = $this->CI->db->query("SELECT COUNT(*) AS count FROM $table WHERE $column = '$str'");
$row = $query->row();
if ($row->count > 0) {
$query = $this->CI->db->query("SELECT COUNT(*) AS count FROM v_redeem WHERE v_serial='$str'");
$row = $query->row();
if ($row->count > 0) {
/// used
return FALSE;
} else {
return TRUE;
}
} else {
//invalid serial
return FALSE;
}
}
The I call the function from the below.
$this->form_validation->set_rules('serial','serial','required|xss_clean|serial_exist[v_info.v_serial]');
This works just fine but my issue how can I get the to different MSG say'n either invalid or used serial?
Hope my question is clear.
Try to set a custom set_message.
like this---
$this->form_validation->set_message('serial_exist', 'Your custom Message.');

I Have made a function add_items. and I Want if the slug already exists in the database then the form_validation runs and shows the error message. and that's work fine if the slug exists. But the main problem is that if I want to insert the new Data in the database which obviously has a different slug then the data is not inserted.
public function add_items()
{
if($this->input->post()){
if($this->input->is_ajax_request()){
$title = $this->input->post('title');
$url_title = url_title($title);
$this->form_validation->set_rules($url_title,'callback_slug_exists');
if($this->form_validation->run() == FALSE)
{
echo "FAIL::Slug Already Exist::error";
return;
}
$item_price = $this->input->post('item_price');
$item_description = $this->input->post('item_description');
$insertData = array('item_title' =>$title,'item_url'=>$url_title,'item_price' =>$item_price,'item_description'=>$item_description,
'big_pic' =>$image_path."/".$image);
$result = $this->common_model->insert_record('store_items',$insertData);
if($result){
echo "OK::Record Inserted Successfully::success";
return;
}
else {
echo "FAIL::Record Insertion Failled::success";
return;
}
}
}
$this->show('admin/add_items.php');
}
Here are The function slug_exists()
function slug_exists($slug)
{
$this->common_model->slug_exists($slug);
}
This is in Model
function slug_exists($slug)
{
$this->db->where('item_url',$slug);
$query = $this->db->get('store_items');
if ($query->num_rows() > 0){
return true;
}
else{
return false;
}
}
This is the insert_record()
function insert_record($tbl, $data)
{
$this->db->insert($tbl, $data);
return $this->db->insert_id();
}
And this is DB Structure
try this:you can post data direct in an array. no need define it.
$insertArray=array(
item_title' =>$this->input->post('title'),
'item_url'=>$this->input->post('url_title'),
'item_price' =>$this->input->post('item_price'),
'item_description'=>$this->input->post('item_description'),
'big_pic' =>$image_path."/".$image);
$this->db->insert('store_items', $insertArray);
Try like this
function slug_exists($slug)
{
$this->db->where('item_url',$slug);
$query = $this->db->get('store_items');
if ($query->num_rows() > 0){
return false;
}
else{
return true;
}
}
If slug already exists then you need to fail the validation to get the error so return false on existing
Also, return the answer/result to a callback function
function slug_exists($slug)
{
return $this->common_model->slug_exists($slug);
}
Update
Controller
if($this->form_validation->run() == FALSE){
echo "FAIL::Slug Already Exist::error";
return;
}else{
$item_price = $this->input->post('item_price');
$item_description = $this->input->post('item_description');
$insertData = array('item_title' =>$title,'item_url'=>$url_title,'item_price' =>$item_price,'item_description'=>$item_description,
'big_pic' =>$image_path."/".$image);
$result = $this->common_model->insert_record('store_items',$insertData);
if($result){
echo "OK::Record Inserted Successfully::success";
return;
}
else {
echo "FAIL::Record Insertion Failled::success";
return;
}
}
I got a codeigniter custom_result_object with this:
$user = $this->CI->db->get_where('users', array('email' => $email), 1)->custom_row_object(0,'entities\User');
and everything looks fine. I can update values with my setters.
Before I'm going to save i check my values with:
die(print_r($user));
and the values are correct.
I put my object in my update method.
$this->CI->db->update('users', $user, "id = ".$user->getId());
But the db is not updating. Am I missing something?
Thx!
EDIT:
So by using CI native db-method i can use:
public function save($user)
{
if($user->getId() == NULL){
$this->CI->db->insert('users', $user);
}else{
$this->CI->db->update('users', $user, "id = ".$user->getId());
}
}
Edit 2:
After some more checking I can see that it's not setting variables that are protected. CI is able to get the object through getters and setters but not able to save back to DB?
public function saveData($tbl,$data,$update = false,$previewStr = false){
$set_str = "NO_QUOTES()";
if(isset($data[$set_str])){
foreach($data[$set_str] as $set_key => $set_value){
$this->db->set($set_key, $set_value, FALSE);
}
unset($data[$set_str]);
}
if(isset($update[$set_str])){
foreach($update[$set_str] as $whr_key => $whr_value){
$this->db->where($whr_key." ".$whr_value,NULL,false);
}
unset($update[$set_str]);
if(is_array($update) and count($update) <= 0){
$update = true;
}
}
if($update == false){
$this->db->insert($tbl, $data);
if($previewStr){
return $this->db->last_query();
}else{
return $this->db->insert_id();
}
}else{
$result = NULL;
if(!is_array($update)){
if(is_array($data) and count($data) > 0){
foreach($data as $field => $value){
$this->db->set($field, $value);
}
}
$result = $this->db->update($tbl);
}else{
$result = $this->db->update($tbl, $data,$update);
}
if($previewStr){
return $this->db->last_query();
}else{
return $result;
}
}
}
public function delData($tbl = false,$where = array()){
if($tbl !== false){
return $this->db->delete($tbl, $where);
}else{
return false;
}
}
public function simpleQuery($query,$return_array = false,$return_single = false)
{
$ac = $this->db->query($query);
if($return_array === false){
return $ac;
}else{
if($return_single === false){
return $ac->result_array();
}else{
return $ac->row_array();
}

}
Use above code in your model and you i am giving you how to update it use below code in your controller you can insert update and delete by above code
$result=$this->Products_model->saveData("customer",array("customer_name"=>$name),array("cust_id"));
I'm sending information from an html form into a php page where I am checking the information against a mysql database.
Right now there are 5 checkboxes plus other variables in the form*(searchbar, radiobuttons, etc)*.
Is there a way to write the conditions without having to have a specific if statement for each path? Otherwise I have to write each specific path, and thats a lot of typing :/
Right now it would look something like:
if($orderBy == "price")
{
if($searchBy == "begin")
{
if($_POST["gameType"] == "RTS")
{
$sql = "select * from gametbl where gme_title like '$title%' and where gme_type = 'RTS' ORDER BY gme_price DESC";
}
}
and for all the conditions, thats going to take way to long. Is there a better way of doing this?
This is essentially what I mean by doing a method chain. You can specify within each method what to do if a specific variable is fed into it. It would dynamically write a statement based on single values. This a series of guesses based on your only bit of code:
<?php
class SQLBuilder
{
protected $order;
protected $sql;
public $statement;
public function Select($columns = false)
{
$this->sql[] = "select";
if(is_array($columns))
$this->sql[] = implode(",",$columns);
else
$this->sql[] = ($columns != false)? $columns:"*";
return $this;
}
public function Where($array = false,$like = false)
{
if($array == false)
return $this;
if(in_array("where", $this->sql))
$this->sql[] = "and";
$this->sql[] = "where";
if(is_array($array)) {
foreach($array as $key => $value)
$where[] = ($like != false)? "`$key` like '%".$value."$'":"`$key` = '".$value."'";
if(isset($where))
$this->sql[] = implode("and",$where);
}
else
$this->sql[] = $array;
return $this;
}
public function From($table = 'gametbl')
{
$this->sql[] = "from";
$this->sql[] = "`$table`";
return $this;
}
public function OrderBy($value = false,$order = false)
{
if($value != false) {
// I am guessing this is order
$heiarchy = ($order == 'begin')? " DESC":" ASC";
if($value == 'price')
$order = "`gme_price`".$heiarchy;
}
if(isset($order))
$this->sql[] = "order by ".$order;
return $this;
}
public function Fetch($return_obj = false)
{
$this->statement = implode(" ",$this->sql);
return ($return_obj != false)? $this:$this->statement;
}
}
// I don't know what your form fields are called, these are just for instances
$_POST['gameType'] = 'RTS';
$_POST['gameTitle'] = 'whatever game';
$_POST['orderBy'] = 'price';
$_POST['list'] = 'begin';
// Create instance of builder
$SQLBuilder = new SQLBuilder();
// This will just accumulate the statement based on fed-in variables.
$sql = $SQLBuilder->Select()
->From()
->Where(array("gme_title"=>$_POST['gameTitle']),true)
->Where(array("gme_type"=>$_POST['gameType']))
->OrderBy($_POST['orderBy'],$_POST['list'])
->Fetch();
echo $sql;
?>
GIVES YOU:
select * from `gametbl` where `gme_title` like '%whatever game$' and where `gme_type` = 'RTS' order by `gme_price` DESC
I have 100 tables or can be more than that,I always need to fetch the record all the time in my application from various table.So writing functions for each and every query its not good coding standard.
$this->db->select();
$this->db->from("table1");
$query = $this->db->get();
return $query->result_array();
$this->db->select();
$this->db->from("table2");
$query = $this->db->get();
return $query->result_array();
$this->db->select();
$this->db->from("table1");
$this->db->where("id",10);
$query = $this->db->get();
return $query->result_array();
I want the good coding standard for this.
Write this code in controller.
$data = $this->common_model->getRecords("table_name", "*", array("field1" => $this->input->post('user_name')));
This will be your function in model (that is common_model).
public function getRecords($table, $fields = '', $condition = '', $order_by = '', $limit = '', $debug = 0) {
$str_sql = '';
if (is_array($fields)) { #$fields passed as array
$str_sql.=implode(",", $fields);
} elseif ($fields != "") { #$fields passed as string
$str_sql .= $fields;
} else {
$str_sql .= '*'; #$fields passed blank
}
$this->db->select($str_sql, FALSE);
if (is_array($condition)) { #$condition passed as array
if (count($condition) > 0) {
foreach ($condition as $field_name => $field_value) {
if ($field_name != '' && $field_value != '') {
$this->db->where($field_name, $field_value);
}
}
}
} else if ($condition != "") { #$condition passed as string
$this->db->where($condition);
}
if ($limit != "")
$this->db->limit($limit);#limit is not blank
if (is_array($order_by)) {
$this->db->order_by($order_by[0], $order_by[1]); #$order_by is not blank
} else if ($order_by != "") {
$this->db->order_by($order_by); #$order_by is not blank
}
$this->db->from($table); #getting record from table name passed
$query = $this->db->get();
if ($debug) {
die($this->db->last_query());
}
$error = $this->db->_error_message();
$error_number = $this->db->_error_number();
if ($error) {
$controller = $this->router->fetch_class();
$method = $this->router->fetch_method();
$error_details = array(
'error_name' => $error,
'error_number' => $error_number,
'model_name' => 'common_model',
'model_method_name' => 'getRecords',
'controller_name' => $controller,
'controller_method_name' => $method
);
$this->common_model->errorSendEmail($error_details);
redirect(base_url() . 'page-not-found');
}
return $query->result_array();
}
I used this code for fetching the record. you just need to pass the table name ,fields name ,the condition and limit.
your codes can actually be in 1 line
$query= $this->db->get('table1')->result_array();
$query= $this->db->get_where('table1', array('id'=>3,'name'=>'tom'))->result_array();
or if you really want a function
function getData($table){
$query=$this->db->get($table)->result_array();
return $query;
}
$data= getData('table1');
I have problem. In my function, return shows only first player from server. I wanted to show all players from server, but i cant get this working. Here is my code:
function players() {
require_once "inc/SampQueryAPI.php";
$query = new SampQueryAPI('uh1.ownserv.pl', 25052); // Zmień dane obok! //
if($query->isOnline())
{
$aInformation = $query->getInfo();
$aServerRules = $query->getRules();
$aPlayers = $query->getDetailedPlayers();
if(!is_array($aPlayers) || count($aPlayers) == 0)
{
return 'Brak graczy online';
}
else
{
foreach($aPlayers as $sValue)
{
$playerid = $sValue['playerid'];
$playername = htmlentities($sValue['nickname']);
$playerscore = $sValue['score'];
$playerping = $sValue['ping'];
return '<li>'.$playername.' (ID: '.$playerid.'), Punkty ('.$playerscore.'), Ping ('.$playerping.')</li>';
}
}
}
}
You're returning from within your loop.
Instead, you should concatenate the results for each iteration and then return that concatenated string outside the loop.
e.g.
$result = "";
foreach($aPlayers as $sValue) {
# add to $result...
}
return $result
function players() {
require_once "inc/SampQueryAPI.php";
$query = new SampQueryAPI('uh1.ownserv.pl', 25052); // Zmień dane obok! //
if($query->isOnline())
{
$aInformation = $query->getInfo();
$aServerRules = $query->getRules();
$aPlayers = $query->getDetailedPlayers();
if(!is_array($aPlayers) || count($aPlayers) == 0)
{
return 'Brak graczy online';
}
else
{
$ret = '';
foreach($aPlayers as $sValue)
{
$playerid = $sValue['playerid'];
$playername = htmlentities($sValue['nickname']);
$playerscore = $sValue['score'];
$playerping = $sValue['ping'];
$ret .= '<li>'.$playername.' (ID: '.$playerid.'), Punkty ('.$playerscore.'), Ping ('.$playerping.')</li>';
}
return $ret;
}
}
}
In a function you can only return ONE value.
Try creating a list of players and return the list when all records have been added to it.
In your case, list of players will result in an array of players
