Comment remplir <select> dropdown de db avec php

Question

Je travaille dans OpenCart et j'essaie de créer une liste déroulante dynamique dans mon formulaire. Je ne peux pas l'obtenir à partir de la base de données. Je continue à obtenir cette erreur:

Warning: Illegal string offset 'firstname' in /var/www/html/Acendia-bit-bucket/vK23o003xdkxLp2-09zxkjekzcDt/controller/campaigns/campaign.php on line 507

Vraiment, je veux juste une liste déroulante qui affiche le prenom et nom de tout le monde dans ce tableau.

Modèle:

public function getCustomers() { 


$query = $this->db->query("SELECT customer_id, firstname, lastname FROM " . DB_PREFIX . "customer"); 


return $query->result_array(); 
//return $query->row; 

}

Controller: (fonctions du contrôleur)

protected function getForm() { 

    $data['heading_title'] = $this->language->get('heading_title'); 
    $data['text_form'] = !isset($this->request->get['event_id']) ? $this->language->get('text_add') : $this->language->get('text_edit');

    $getCustomers = $this->model_campaigns_campaign->getCustomers(); 

    foreach ($getCustomers as $customers) {

Vue:

<div class="col-sm-5 col-sm-push-1 form-group required> 
        <label class="col-sm-2 control-label" for="input-campaign-owner"><?php echo $entry_owner; ?></label> 
       <select name="customer-list" id="customer-list" > 
        <?php 
       foreach ($customer_list as $list){ 
       echo "<option value=''>$list['customer_firstname']</option>"; 
       } 
       ?> 

        </select> 
       </div> 

Answer 1

Je pense qu'il devrait être $query->rows; dans le modèle et il vous suffit $data['customers'] = $this->model_campaigns_campaign->getCustomers(); dans le contrôleur, puis afficher en vue:

<div class="col-sm-5 col-sm-push-1 form-group required"> 
    <label class="col-sm-2 control-label" for="input-campaign-owner"><?php echo $entry_owner; ?></label> 
    <select name="customer-list" id="customer-list"> 
    <?php foreach ($customers as $customer) { ?> 
     <option value="<?php echo $customer['customer_id']; ?>"><?php echo $customer['firstname'] . ' ' . $customer['lastname']; ?></option> 
    <?php } ?> 
    </select> 
</div> 

Answer 2

Je crois que le problème se trouve dans votre citant dans l'écho. En outre, il y a <?php et ?> étiquettes dans votre déclaration d'écho qui ne sont pas nécessaires. Essayez ce qui suit, en prenant acte des modifications apportées à votre déclaration d'écho:

<select name="customer-list" id="customer-list" > 
<?php 
foreach ($customer_list as $list){ 
    echo "<option value=''> 
    $list['customer_firstname'] 
    </option>"; 
} 
?> 

En outre, return $query->row; devrait probablement être return $query->result_array(); dans votre modèle.
