Problems when saving to the database with html?

Question

PHP

When creating a post, there is a function that turns the normal html record into a database example
, but when editing a post, it saves like this

<p><span style="font-family: Georgia,serif;"><em&gt

The functions are different sent through the form and ajax
one noticed that the creation of the post has a Wo_Markup function that converts the tags into a normal view How can I substitute it so that when editing it also has a normal
ajax view

if ($f == "update-post") {
    if (Wo_CheckSession($hash_id) === true) {
        if (empty($_POST['title']) || empty($_POST['postText']) || empty($_POST['category'])) {
            $error = $error_icon . $wo['lang']['please_check_details'];
        } else {
            if (strlen($_POST['title']) < 10) {
                $error = $error_icon . $wo['lang']['title_more_than10'];
            }
           
        
            if (!in_array($_POST['category'], array_keys($wo['feed_categories']))) {
                $error = 'erer';
            }
        }
        if (empty($error)) {
            $registration_data = array(
                'title' => $_POST['title'],
                'postText' => $_POST['postText'],
                'category' => $_POST['category'],
                                'tags' => $_POST['post_tags']

            );
            if (Wo_UpdateFeed($_GET['post_id'], $registration_data)) {
                if (isset($_FILES["postPhoto"])) {
                    $fileInfo           = array(
                        'file' => $_FILES["postPhoto"]["tmp_name"],
                        'name' => $_FILES['postPhoto']['name'],
                        'size' => $_FILES["postPhoto"]["size"],
                        'type' => $_FILES["postPhoto"]["type"],
                        'types' => 'jpeg,jpg,png,bmp,gif',
                        'crop' => array(
                            'width' => 600,
                            'height' => 380
                        )
                    );
                    $media              = Wo_ShareFile($fileInfo);
                    $mediaFilename      = $media['filename'];
                    $image              = array();
                    $image['user_id']      = $wo['user']['user_id'];
                    $image['postPhoto'] = $mediaFilename;
                    Wo_UpdateFeed($_GET['post_id'], $image);
                }
                $data = array(
                    'message' => 'asd',
                    'status' => 200,
                    'url' => Wo_SeoLink('index.php?link1=home')
                );
            }
        } else {
            $data = array(
                'status' => 500,
                'message' => $error
            );
        }
    }
    header("Content-type: application/json");
    echo json_encode($data);
    exit();
}

php

function Wo_UpdateFeed($id = 0, $update_data = array()) {
    global $sqlConnect, $wo;
    $update = array();
    if ($wo['loggedin'] == false) {
        return false;
    }
    if (empty($update_data)) {
        return false;
    }
    if (empty($id)) {
        return false;
    }

     
    $id = Wo_Secure($id);

    foreach ($update_data as $field => $data) {
        $update[] = '`' . $field . '` = \'' . Wo_Markup(Wo_Secure($data, 0, false)) . '\'';
    }
    $impload   = implode(', ', $update);
    $query_one = "UPDATE " . T_POSTS . " SET {$impload} WHERE `post_id` = {$id} ";
    $query     = mysqli_query($sqlConnect, $query_one);
    return $query;
}

Somewhere in your code you have htmlspecialchars or some similar escape function. Try to track at what point the text "spoils".

Copy its call to the place where you need it.
