Hello I am trying to build my first restful web service and im using the instruction from lorna jane mitchell blog.
If the req comes through this Url : http://localhost:8888/lorna/index.php/tree/getpath?node_id=75
i call the function getpath passing node_id
The function get path looks like this :
class NestedSet
{
public function getPath($id) {
$sql = "SELECT p." . $this->pk . ", p." . $this->name . " FROM ". $this->table . " n, " . $this->table . " p WHERE n.lft BETWEEN p.lft AND p.rgt AND n." . $this->pk ." = " . $id . " ORDER BY p.lft;";
$result = $this->db->query($sql);
if ($result->num_rows == 0) {
return $this->error(1, true);
}
$path = array();
$i = 0;
while ($row = $result->fetch_assoc()) {
$path[$i] = $row;
$i++;
}
return $path;
}
}
Now i want to pass this variable $path to the class JsonView that looks like this :
class JsonView extends ApiView {
public function render($path) {
header('Content-Type: application/json; charset=utf8');
echo json_encode($path);
return true;
}
}
class ApiView {
protected function addCount($data) {
if(!empty($data)) {
// do nothing, this is added earlier
} else {
$data['meta']['count'] = 0;
}
return $data;
}
}
Any Idea on how can I pass the variable $path or any other variable through this JsonView Class.
Thank you very much for your time :)
UPDATE This is the code for creating the nested class object
public function getAction($request) {
$data = $request->parameters;
if(isset($request->url_elements[2])) {
switch ($request->url_elements[2]) {
case 'getpath':
$id = $data['node_id'];
$nested = new NestedSet();
$nested->getPath($id);
$api = new JsonView();
$api->render($path);
break;
default:
# code...
break;
}
} else {
$nested = new NestedSet();
echo $nested->treeAsHtml();
}
}
Just create object of JsonView and then call the function render using that object.
$api = new JsonView;
$api->render($path);

I'm trying for a search function, I made a public function in a file called Topic, and I tried calling the method in the index.php, however it doesn't show anything, I think the problem lies with the while statement, but i'm not entirely sure.
Topic.php
class Topic{
public function searchPosts($postTags)
{
$conn = Db::getInstance();
$statementSearch = $conn->prepare("SELECT * FROM topics INNER JOIN posttopic ON topics.topicID=posttopic.topicID INNER JOIN posts ON posttopic.postID=posts.postID WHERE naam = :naam");
$statementSearch->bindValue(":naam", $postTags);
return $statementSearch->execute(array());
}
}
Index.php
spl_autoload_register(function ($class) {
include_once("classes/" . $class . ".php");
});
$_SESSION['KEYWORD'] = array();
$postArray = array();
//$allResults2 = array();
if (isset($_POST['Find'])) {
if (!empty($_POST['Find'])) {
$searchTopic = new Topic();
$postTags = $_POST['naam'];
$searchTopic->searchPosts($postTags);
while ($row = $statementSearch->fetch(PDO::FETCH_ASSOC)) {
$_SESSION['KEYWORD'][] = $row['postImageUrl'];
$postArray[] = $row['postID'];
}
}
if (count($_SESSION['KEYWORD']) === 0) {
$error = "Sorry no results!";
}
}
This is the html where it should be printed.
<?php
foreach (array_combine($_SESSION['KEYWORD'], $postArray) as $imageLink => $i) {
echo "<a href='./pin.php?postid=$i' ><img src='" . $imageLink . "'</a>";
}
?>
I do have a search form on a page which search records from a table in my database. I want to show how many results each query gives us. All this is written in codeigniter.
All my code on that page:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function index() {
$data['title'] = "Welcome | randomsite";
$data['html'] = "";
if($this->input->post()) {
$uq = $this->security->xss_clean($this->input->post('query'));
if(trim($uq) != "") {
$searchBy = $this->security->xss_clean($this->input->post('searchBy'));
$searchByJSON = json_encode(array(1 => "Email", 2 => "Username", 3 => "IP", 4 => "FullName", 5 => "Phone"), JSON_FORCE_OBJECT);
if(isset(json_decode($searchByJSON)->$searchBy)) {
$start = microtime(true);
$this->db->from('Databases');
$rs = $this->db->get()->result();
$end = microtime(true);
$data['html'] .= "Search completed in: " . ($end - $start) . " seconds.<p></p>";
foreach($rs as $row) {
$this->db->distinct();
$this->db->select('Username, Password, Email, FullName, IP, Phone, salt');
$this->db->from('Accounts');
$this->db->where(json_decode($searchByJSON)->$searchBy, $uq);
$this->db->where('DatabaseID', $row->ID);
$query = $this->db->get();
if($query->num_rows() > 0) {
if($searchBy == 5 && $query->row()->Phone == 0) {
break;
}
$resultsHTML = "";
foreach($query->result() as $qr) {
$resultsHTML .= "<div class='card-block-results' style='table-layout:fixed; word-wrap:break-word;'><table class='table table-hover' style='font-size:13px;'>";
foreach($qr as $key => $value) {
if(!empty($value)) {
if($key == "FullName") {
$key = "Full Name";
}
$resultsHTML .= "<tr><td>" . $key . ": " . $value . "</td></tr>";
}
}
$resultsHTML .= "</table></div>";
}
$data['html'] .= $row->Website . " has: <b style='color:lime;'>" . $query->num_rows() . "</b> result(s) found. This data was hacked on approximately " . $row->Date . ". <button class='btn btn-success btn-sm' style='margin-bottom:5px;' id='button" . $row->ID . "'>view results</button><div id='results" . $row->ID .

"</div></div><script type='text/javascript'>$('#button" . $row->ID . "').click(function() { $(this).hide(); $('#results" . $row->ID . "').show(); });</script><br>";
}
}
if($data['html'] == "Search completed in: " . ($end - $start) . " seconds.<p></p>") {
$data['html'] .= "No results found!<p></p>Are you searching in the right fields? Searching for an email in the phone number field will not work.<br>Make sure first and last names are correct. Example: Mike Tyson";
}
$data['html'] .= "<br><br><br>";
$this->db->from('Lookups');
$query = $this->db->get();
$new_lookup = $query->row()->Number + 1;
$qdata = array(
"Number" => $new_lookup
);
$this->db->update('Lookups', $qdata);
}
} else {
$data['html'] = '<div class="alert alert-danger">×Please enter something in your query before searching!</div>';
}
}
$this->load->view('welcome', $data);
}
}
So how can I add that into every time someone is searching? Like 'Query had x results.'
Like this:
I searched on many different sites about this but I couldn't find anything for my specific question.
you have already used it in your code,
$query->num_rows()
will give you the number of rows u get from the query.
i think this is abusing a framework like CI - i give you some insights in to this framework - if you are willing to learn, study this piece of code because
you nearly don't use any of his built in functionality
in my opinion you've to restructure your code to such an extent that you don't even recognize your previous attempt ;)
i'll try to give you a hunch - but in order to understand - you've to work with this code
put in your models folder the following models
Database Model

pS: maybe there are some typos because i just wrote it down
I have three functions that returns all parents for specific child with user_id with recursive query.
All these functions works good ..but the problem begins when I start use foreach loop to return multiple user parent names in function
merge_comments_data..
note : t_relation means = parent_id
class News extends front_end {
public $parents_names;
function merge_comments_data($related_comments) {
foreach ($related_comments as $comment) {
$full_name = $this->get_parents_names($comment['cn_visitor_id']);
}
echo "<pre>";
print_r($names);
echo "</pre>";
exit;
}
//// all these function to get full parent names by user id
function get_parents_names($user_id = 0) {
$this->user_parent_name($user_id);
echo $this->parents_names;
}
function user_parent_name($user_id = 0) {
// clear the variable at first
$result = $this->get_parents($user_id);
if (is_object($result)) {
$this->parents_names .= ' ' . $result->t_name . ' ';
if ($result->t_relation != 0) {
$this->user_parent_name($result->t_relation);
}
}
}
public function get_parents($user_id = 0) {
$result = $this->db->query("SELECT * FROM d_tree where t_id = '$user_id'");
if (is_object($result->row())) {
$result = $result->row();
} else {
$result = '';
}
return $result;
}
i create function called empty_fields but i can't figure out, to make it work..
<?php
function empty_fields($field_name)
{
if(!empty($order[$field_name]))
{
$output = "<li>Indigofera - " . $order[$field_name] . "Kg</li>";
} else { $output = null; }
return $output;
}
to display in html
<?php empty_fields('indigofera'); ?>
Change
if(!empty($order['$field_name'])){
to
if(!empty($order[$field_name])){
'$field_name' does not evaluate to anything and it will search for
key '$field_name' in the $orders array everytime, hence will not work.
Hope it works.
If you use $order as a global variable, use:
function empty_fields($field_name)
{
global $order;
$output = null;
if(!empty($order[$field_name]))
{
$output = "<li>Indigofera - " . $order[$field_name] . "Kg</li>";
}
return $output;
}
and use it:
<?php echo empty_fields('indigofera'); ?>
EDIT: the OOP way:
class Orders
{
private $order = null;
public function get_order()
{
$this->order = //....
}
public function empty_fields($field_name)
{
if(!isset($this->order) || empty($order[$field_name])) return;
return "<li>Indigofera - " . $order[$field_name] . "Kg</li>";
}
}
and use it:
<?php
$orders = new Orders();
$orders->get_order();
echo $orders->empty_fields("indigofera");
This question already has answers here:
Call to a member function on a non-object [duplicate]
(8 answers)
Closed 10 years ago.
The class below is my first attempt at writing my own OOP application. I've used procedural for a while and the OO techniques are not coming as easily as I'd hoped.
The class is designed to put together input elements for HTML forms, optionally using SQL table records. I'm starting with the select box and will add more when I get this much working.
So the problem is that I'm getting
"Call to a member function get_table() on a non-object" on the 'public function get_table()' line of the Class code below.
I'm not sure why this is happening. Help/tips would be GREATLY appreciated.
and now the code:
Application:
$_input = new html_form_input();
$_input->set_input_type('select');
$_input->set_table('stores');
$_input->set_fieldname_id('store_id');
$_input->set_fieldname_desc('store_name');
$_input->set_sql_order(' ORDER BY store_name ASC ');
$_input->set_select();

With your getters, instead of using $this->$var it should be $this->var, for example $this->table and not $this->$table.
In the following code, $table hasn't been initialised.
public function set_query_form_data()
{
global $dbx;
$debug = true;
$_debug_desc = "<span style='color:blue;'>function</span> <b>set_query_form_data</b>()";
if ($debug) { echo "<p>BEGIN $_debug_desc <blockquote>"; }
$table->get_table();
You probably intend it to be $this, i.e. "the object currently being used":
public function set_query_form_data()
{
global $dbx;
$debug = true;
$_debug_desc = "<span style='color:blue;'>function</span> <b>set_query_form_data</b>()";
if ($debug) { echo "<p>BEGIN $_debug_desc <blockquote>"; }
$this->get_table();
The problem is in your set_query_form_data method:
public function set_query_form_data() {
// $table is no object
$table->get_table();
// you should use this instead
$this->table
}
Note:
// Are you sure with this calls? Shouldn't it be $this->array_input_options ?
return $this->$array_input_options;
You're making use of variable functions/dereferencing, unintentionally. Example:
$foo = 'name';
echo $object->$foo; // same as echo $object->name
Object properties and methods do not need to be prefixed with $.
With the pointers from the other answers and some more RTM, I got the basic script working. In particular, I removed the "$" from property names and accessed the properties of $this instead of calling get_* methods.
Application:
$array_input_options = array(
'include_blank_option' => 1,
'disabled' => 0,
'multiple' => 0,
'size' => '',
'style' => '',
'id' => '',
'class' => '',
'javascript' => '',
);
