I wanted to pass some values to the view.
The $result may be 0 or 1 or '' and I tried to use this below code:
public function whatwedo($result='')
{
$result = array();
$result['status'] = $result;
$this->load->view('admin/whatwedo',$result);
}
public function add_whatwedo()
{
//$this->load->library('form_validation');
$this->form_validation->set_rules('text-input','Title','required');
if($this->form_validation->run() != true)
{
$result = 0;
$this->whatwedo($result);
}
else
{
$this->load->model('admin_model');
$result = $this->admin_model->ins_whatwedo($this->input->post());
//print_r($result);exit();
$this->whatwedo($result);
}
}
And in the view:
<?php
print_r($status);
?>
But, the $status is Array ( )
The problem is this line:
$result = array();
Because now the $result variable is an empty array so when you create the index status on result you assign it an empty array.
To fix you can do something like:
public function whatwedo($input = '')
{
$result['status'] = $input;
$this->load->view('admin/whatwedo', $result);
}
or even...
public function whatwedo($input = '')
{
$this->load->view('admin/whatwedo', ["status" => $input]);
}

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 trying to load a website url from a textfile, then unset this string from an array and pick a random website from the array.
But once I try to access the array from my function the array would return NULL, does someone know where my mistake is located at?
My current code looks like the following:
<?php
$activeFile = 'activeSite.txt';
$sites = array(
'http://wwww.google.com',
'http://www.ebay.com',
'http://www.icloud.com',
'http://www.hackforums.net',
'http://www.randomsite.com'
);
function getActiveSite($file)
{
$activeSite = file_get_contents($file, true);
return $activeSite;
}
function unsetActiveSite($activeSite)
{
if(($key = array_search($activeSite, $sites)) !== false)
{
unset($sites[$key]);
return true;
}
else
{
return false;
}
}
function updateActiveSite($activeFile)
{
$activeWebsite = getActiveSite($activeFile);
if(!empty($activeWebsite))
{
$unsetActive = unsetActiveSite($activeWebsite);
if($unsetActive == true)
{
$randomSite = $sites[array_rand($sites)];
return $randomSite;
}
else
{
echo 'Could not unset the active website.';
}
}
else
{
echo $activeWebsite . ' did not contain any active website.';
}
}
$result = updateActiveSite($activeFile);
echo $result;
?>
$sites is not avaliable in unsetActiveSite function you need to create a function called "getSites" which return the $sites array and use it in unsetActiveSite
function getSites(){
$sites = [
'http://wwww.google.com',
'http://www.ebay.com',
'http://www.icloud.com',
'http://www.hackforums.net',
'http://www.randomsite.com'
];
return $sites;
}
function unsetActiveSite($activeSite)
{
$sites = getSites();
if(($key = array_search($activeSite, $sites)) !== false)
{
unset($sites[$key]);
return true;
}
else
{
return false;
}
}
I want to include like clause in the case of last_name.This is my controller code used for search box.I want to compare form value last_name with db value family_name.
public function filtered_volunteer_details()
{
$user_data = $this->session->userdata("logged_user");
$tab_result = array();
if (is_array($user_data) && $user_data["user_role"] == "staff")
{
if ($this->input->method() == "post")
{
$condition = array();
$data = $this->input->post();
if(isset($data["membership_number"]) && $data["membership_number"]!= "")
{
$condition["membership_number"]=trim($data["membership_number"]);
}
if(isset($data["last_name"]) && $data["last_name"]!= "")
{
$condition["family_name "]=trim($data["last_name"]);
}
$this->load->model(array(
"Users"));
$result = $this->Users->get_volunteers("*",$condition);
$volunteer_tbl_list=array();
foreach($result as $volunteer_results)
{
$volunteer_tbl_list[] = $this->load->view("staff/manage_volunteer/volunteer_list_tbl_row", $volunteer_results, TRUE);
}
echo json_encode(array(
"status" => "success",
"volunteer_tbl_list" => $volunteer_tbl_list));
return;
}
}
echo json_encode(array(
"error" => "true",
"msg" => "Invalid Access."));
return;
}
This is my model code
public function get_volunteers($fields = "*",$condition=array())
{
$condition["staff"]="N";
$this->db->select($fields);
$query = $this->db->get_where(self::$tbl_name, $condition);
//var_dump($this->db->last_query());
return( $query->result() );
}
Try adding a $this->db->like() to the query in get_volunteers(). documentation
public function get_volunteers($fields = "*",$condition=array())
{
$condition["staff"]="N";
$this->db->select($fields);
$this->db->like($condition);
$this->db->from(self::$tbl_name);
return( $query->result() );
}
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');
Codeigniter when i submit more than one option of form_multiselect(), Only just the last one that saved on database.
in my view :
<label>Trimestres :</label>
<div class="controls" >
<?php $options = array(
'trim1' => ' Premier trimestre (Janv,Fév,Mars)',
'trim2' => ' Deuxiéme trimestre (Avril,Mai,Juin)',
'trim3' => ' Troisiéme trimestre (Juill,Aout,Sept)',
'trim4' => ' Quatriéme trimestre (Oct,Nov,Déc)',
);
echo form_multiselect('trimestres', $options , $this->input->post('trimestres') ? $this->input->post('trimestres') : $participant_sport->trimestres, 'id="trim"'); ?>
</div>
</div>
in my controller :
public function inscriresport ($id = NULL)
{
// Fetch a participant or set a new one
if ($id) {
$this->data['participant_sport'] = $this->participantsport_m->get($id);
count($this->data['participant_sport']) || $this->data['errors'][] = 'participant non trouvé';
}
else {
$this->data['participant_sport'] = $this->participantsport_m->get_new();
}
// Process the form
$this->participantsport_m->array_from_post(array('matricule', 'nom', 'prenom', 'beneficiaire', 'sexe', 'telephone', 'date_naissance', 'date_inscription_sport', 'trimestres' ,'sport_montant_paye', 'sport_debut_periode', 'sport_fin_periode'));
$this->participantsport_m->save($data, $id);
redirect('admin/agent/profile/3608');
}
// Load the view
$this->data['subview'] = 'admin/agent/inscriresport';
$this->load->view('admin/_layout_main', $this->data);
}
The function array_from_post() is defined on application\core\MY_Model.php :
public function array_from_post($fields){
$data = array();
foreach ($fields as $field) {
$data[$field] = $this->input->post($field);
}
return $data;
}
in my model :
public function get_new()
{
$participant_sport = new stdClass();
$participant_sport->matricule = '';
$participant_sport->nom = '';
$participant_sport->prenom = '';
$participant_sport->beneficiaire = '';
$participant_sport->sexe = '';
$participant_sport->telephone = '';
$participant_sport->date_naissance = '';
$participant_sport->date_inscription_sport = '';
$participant_sport->trimestres = '';
$participant_sport->sport_montant_paye = '';
$participant_sport->sport_debut_periode = '';
$participant_sport->sport_fin_periode = '';
return $participant_sport;
}
Any help Please? i think that must be an array but i don't know how to do it?
i thing that i must do something like that :
foreach($_POST["strategylist[]"] as $s) {
# do the insert here, but use $s instead of $_POST["strategylist[]"]
$result=mysql_query("INSERT INTO sslink (study_id, strategyname) " .
"VALUES ('$id','" . join(",",$s) . "')")
or die("Insert Error: ".mysql_error());
}
to insert more than one option selected in one row but i don't know how to do it in codeigniter
the get() function :
public function get($id = NULL, $single = FALSE){
if ($id != NULL) {
$filter = $this->_primary_filter;
$id = $filter($id);
$this->db->where($this->_primary_key, $id);
$method = 'row';
}
elseif($single == TRUE) {
$method = 'row';
}
else {
$method = 'result';
}
if (!count($this->db->ar_orderby)) {
$this->db->order_by($this->_order_by);
}
return $this->db->get($this->_table_name)->$method();
}
If select name (in HTML tag) is trimestres it will always remember last selection. Use trimestres[] as a name to get array with all selected values`
<select name="trimestres[]" multiple …
By the way:
I don't know how array_from_post() works but it has to change trimestres[] values to one string to save all of them in one column. It is hard to search/add/delete one value if all values are in one string. It is "SQL Antipattern". You could do another table in database for trimestres - one value in one row.
Edit:
It will change all arrays into string with elements connected by ,. Not tested.
public function array_from_post($fields){
$data = array();
foreach ($fields as $field) {
// print_r($this->input->post($field));
if( is_array( $this->input->post($field) ) ) {
$data[$field] = join(",", $this->input->post($field));
} else {
$data[$field] = $this->input->post($field);
}
// print_r($data[$field]);
}
return $data;
}
Edit:
Not tested.
public function inscriresport ($id = NULL)
{
// Fetch a participant or set a new one
if ($id) {
$this->data['participant_sport'] = $this->participantsport_m->get($id);
count($this->data['participant_sport']) || $this->data['errors'][] = 'participant non trouvé';
// explode to array
// print_r($this->data['participant_sport']->trimestres); // test before explode
// $this->data['participant_sport']['trimestres'] = explode(",", $this->data['participant_sport']['trimestres']);
$this->data['participant_sport']->trimestres = explode(",", $this->data['participant_sport']->trimestres);
// print_r($this->data['participant_sport']->trimestres); // test after explode
} else {
$this->data['participant_sport'] = $this->participantsport_m->get_new();
}
// rest of code
}
There is a easy way to solve this problem that I found today.
you have to serialize the $_POST['trimestres'] array just after array_form_post .
the this array will save to database as a serialize string.
public function inscriresport ($id = NULL)
{
// Fetch a participant or set a new one
if ($id) {
$this->data['participant_sport'] = $this->participantsport_m->get($id);
count($this->data['participant_sport']) || $this->data['errors'][] = 'participant non trouvé';
}
else {
$this->data['participant_sport'] = $this->participantsport_m->get_new();
}
// Process the form
$this->participantsport_m->array_from_post(array('matricule', 'nom', 'prenom', 'beneficiaire', 'sexe', 'telephone', 'date_naissance', 'date_inscription_sport', 'trimestres' ,'sport_montant_paye', 'sport_debut_periode', 'sport_fin_periode'));
$data['trimestres'] = serialize($_POST['trimestres']);
$this->participantsport_m->save($data, $id);
redirect('admin/agent/profile/3608');
}
// Load the view
$this->data['subview'] = 'admin/agent/inscriresport';
$this->load->view('admin/_layout_main', $this->data);
}
When you just need this data back form database just use php unserialize() function .
Hope it will help to do this easily ....
-thanks
