如何在修复中添加功能 - 在 model php 文件中的特定 ID 中更新数据库表中的单元格

Question

I make a remake of an extension so I stuck in the last work that I must to do. I created a twig for admin which displays a list that take data from a table in the database. In each row of the list I created a button that I want to fix specific cell of the table. So each line has its own id.

See the image from page list:

I made the controller file but I stuck in model file that must do the rest work.

In the following code I have to change something so that by pressing the repair button it reads the specific id.

public function repairSaveCarts($link_id=" ") {
        $this->db->query("SELECT * FROM " . DB_PREFIX . "save_cart WHERE link_id = '" . (int)$link_id . "'");

        $db_id = $this->db->getLastId();
            $end_url = base64_encode(serialize($db_id));
            $url = $this->config->get('config_url').$end_url;
            
            $this->db->query("UPDATE " . DB_PREFIX . "save_cart SET shorturl = '" . $this->db->escape($url) . "' WHERE link_id = '" . (int)$db_id . "'");
    }

I thing that the change must be done in $db_id = $this->db->getLastId();line but I'm not sure. Someone that can help please.

I make it work. I had a small syntax error in request->get | post request->get | post at controller and for this reason the model didn't get the correct id from button.

public function repairSaveCarts($link_id) {
        
        $end_url = base64_encode(serialize((int)$link_id));
        
        $url = $this->config->get('config_url').$end_url;
        
        $this->db->query("UPDATE " . DB_PREFIX . "save_cart SET shorturl = '" . $this->db->escape($url) . "', date_added = NOW() WHERE link_id = '" . (int)$link_id . "'");
        
    
        
        return $query->row;
    }

One thing I notice with serialize is that when the model got the id from the controller it received it as a spring value and not as an int value. The result was to give as example for

id 10 ---> serialize value= s:2:"10";

To fix this i add in model the (int) value after serialize and now give me the correct results

id 10 ---> serialize value= i:10; .

The only problem now is that when the module save to database from frond-end page give me the full URL site:

https://www.example.com/aToxMDs=

but when in admin side the functionRepair save to database give me only:

aToxMDs=

The line $url = $this->config->get('config_url').$end_url; seems that doesn't work.

What i must edit to add the store url before the $end_url ???

Here's a revised version of the function for your model class:

public function repairSaveCarts($link_id, $base) {
    $end_url = base64_encode(serialize($link_id));
    $url = $base.$end_url;
        
    $this->db->query("UPDATE " . DB_PREFIX . "save_cart SET shorturl = '" . $this->db->escape($url) . "' WHERE link_id = '" . (int)$link_id . "'");
}

You should also cater for HTTPS not just HTTP, so add the following to the controller to get the site Url and pass that value to the 'repair' function. This should be done just before the existing call to the model function:

// check if the request was made over HTTPS or not
if ($this->request->server['HTTPS']) {
    $server = $this->config->get('config_ssl');
} else {
    $server = $this->config->get('config_url');
}

$this->whateveryourmodelnameis->repairSaveCarts($link_id, $server);

And finally i make it. I replace this:

public function repairSaveCarts($link_id, $base) {
    $end_url = base64_encode(serialize($link_id));
    $url = $base.$end_url;
        
    $this->db->query("UPDATE " . DB_PREFIX . "save_cart SET shorturl = '" . $this->db->escape($url) . "' WHERE link_id = '" . (int)$link_id . "'");
}

with this on model file:

public function repairSaveCarts($link_id) {
    $end_url = base64_encode(serialize((int)$link_id));
    if ($this->request->server['HTTPS']) {
    $url = HTTPS_CATALOG . $end_url;
    } else {
    $url = HTTP_CATALOG . $end_url;
    }
        
    $this->db->query("UPDATE " . DB_PREFIX . "save_cart SET shorturl = '" . $this->db->escape($url) . "', date_added = NOW() WHERE link_id = '" . (int)$link_id . "'");
}

Thank you Daniel for your help.
