Question

i want to know how can i pass a parameter (Get) to my model to search in my database and return the results?

I make a Research function for all the products in my database

Here’s my code :

Controller :

function recherche2($search){
    $this->load->model('ordiDepotModele');
    $resultat = $this->ordiDepotModele->rechercher($search);
    $i=0;
    foreach ($resultat->result() as $row){
        $item = array();
        $item['num'] = $row->idProduit;
        $item['nomProduit'] =  $row->nomProduit;
        $item['prix'] =  $row->prixVente;   
        $listeitems[$i] = $item;
        $i++;
    }
    $data['item'] = $listeitems;
 }

Model:

function rechercher($search){
    $query = $this->db->query("SELECT * FROM produit WHERE nomProduit LIKE '%".$search."%'");

    return $query;
}

View:

 if(isset($item)){
    for($i = 0; $i<count($item);$i++){?>    
        <div class = "res_item">
            <div class = "res_img">
                <img src = "<?php echo $image; ?>/computer2.png"/>
            </div>
            <div class = "res_info">
                <div class "res_num">
                    <label class = "titre_prod">
                        Numéro : 
                    </label>
                    <span class = "info_prod"> <?php echo $item[$i]['num']?> </span>
                </div>
                <div class "res_name">
                    <label class = "titre_prod">
                        Nom : 
                    </label>
                    <span class = "info_prod"> <?php echo $item[$i]['nomProduit']?> </span>
                </div>
                <div class "res_prix">
                    <label class = "titre_prod">
                        Prix : 
                    </label>
                    <span class = "info_prod"> <?php echo $item[$i]['prix']?> $ </span>
                </div>
                <div class "res_cat">
                    <label class = "titre_prod">
                        Catégorie : 
                    </label>
                    <span class = "info_prod"> Test </span>
                </div>  
            </div>
        </div>  
 <?php 
     } 
 }
 else 
     echo 'Aucun résultat obtenu';      

Thanks to all

You need to enable querystrings in your application/config/config.php

$config['enable_query_strings'] = TRUE;

BUT you dont need it at this point. you should just pass it as a URL segment.

function recherche2($keyword) {
    $this->load->model('ordiDepotModele');
    $resultat = $this->ordiDepotModele->rechercher($keyword);
    $data['nom'] = $keyword;
...

ALSO I think your problem is that you pass the value to your model like this:

 $resultat = $this->ordiDepotModele->rechercher($data['nom']);

which gets the “nom” value out of the array as a single value.. (assuming you have only one search box)

then in your alert you do this:

function rechercher($data){
     echo "<script>alert('".$data['nom']."');</script>";

Which is reading a value out of an associative array, but at this point $data is not an array, its a local variable which contains a string.
You could view it if you did

 echo $data;

// EDIT
sorry I cant really post formatted code in a comment.
try this:

public function test() {
    echo '['.$this->input->get('search').']';
    echo '<form method="GET">';
    echo '<input type="input" name="search" /><input type="submit" />';
    echo '</form>';
}
