Perfetto — questi avvisi nel log Apache indicano warning PHP (non errori fatali), ma andrebbero corretti per pulire il codice e prevenire futuri problemi su PHP 8.4, che è molto rigido con le chiavi e variabili non definite.
Vediamo in dettaglio cosa succede e come risolvere in modo stabile.

🔍 1. Undefined array key "feedback_id"

File: /oc-content/plugins/backoffice_manager/function/feedback.php (linee 98–120 circa)

Causa: viene letto $_POST['feedback_id'] o $_GET['feedback_id'] senza prima verificare che esista.

Fix consigliato:

php
Copia codice
$feedback_id = $_POST['feedback_id'] ?? $_GET['feedback_id'] ?? null;
if ($feedback_id === null) {
    // opzionale: log o valore di default
    $feedback_id = 0;
}

Perfetto — adesso è chiaro che il plugin backoffice_manager genera decine di PHP Warning perché legge variabili da $_POST o $_GET che non sempre sono impostate.
Questi messaggi non bloccano il sito, ma sporcano i log e peggiorano le performance.
Ti mostro come sistemare in modo definitivo e pulito.

🔧 Correzioni passo-passo

1️⃣ File coinvolto

/var/www/au/oc-content/plugins/backoffice_manager/function/feedback.php

Le linee 89–120 circa contengono chiamate tipo:

php
Copia codice
$score_quality = $_POST['score_quality'];
$feedback_id   = $_POST['feedback_id'];

2️⃣ Sostituisci tutte le letture dirette con il costrutto ??

Aggiungi una riga all’inizio della funzione che usa questi campi:

php
Copia codice
$feedback_id         = $_POST['feedback_id'] ?? $_GET['feedback_id'] ?? null;
$score_quality       = $_POST['score_quality'] ?? 0;
$score_delivery      = $_POST['score_delivery'] ?? 0;
$score_communication = $_POST['score_communication'] ?? 0;

Così PHP non genera più warning se le chiavi non sono presenti.

3️⃣ Variabile $user_id non definita

In form/form_feedback_add.php (linea 2) aggiungi:

php
Copia codice
$user_id = osc_logged_user_id() ?? 0;

oppure, se viene passato via POST:

php
Copia codice
$user_id = $_POST['user_id'] ?? 0;

4️⃣ Undefined array key "HTTP_CLIENT_IP" (linea 137)

In PHP 8.4 serve controllare prima di accedere a $_SERVER:

php
Copia codice
$ip = $_SERVER['HTTP_CLIENT_IP']
    ?? $_SERVER['HTTP_X_FORWARDED_FOR']
    ?? $_SERVER['REMOTE_ADDR']
    ?? '0.0.0.0';

5️⃣ Undefined variable $height (profile_picture/index.php:203)

Aggiungi un valore predefinito prima dell’uso:

php
Copia codice
$height = $height ?? 100;

6️⃣ Undefined array key "item_status" e "status_name"

Nel file /oc-content/plugins/listing_status/index.php (linee 27–28):

php
Copia codice
$item_status = $_POST['item_status'] ?? '';
$status_name = $_POST['status_name'] ?? '';

✅ Suggerimento finale

Per individuare subito questi casi nel plugin intero:

bash
Copia codice
grep -R "POST" /var/www/au/oc-content/plugins/backoffice_manager/ | grep "\['"

E per ogni chiave acceduta direttamente ($_POST['...'] o $_GET['...']), sostituiscila con $_POST['chiave'] ?? null.

Se vuoi, posso mostrarti un patch completo pronto da incollare (solo per feedback.php) che elimina tutti i warning senza cambiare la logica.
Vuoi che te lo generi?

Perfetto, ottimo: questo è esattamente il file feedback.php che genera i warning nel log Apache.
Le righe incriminate sono quelle dove accede a chiavi come
$fb['feedback_id'], $fb['score_quality'], ecc., senza controllare se esistono.
Ti lascio qui sotto una versione corretta e compatibile con PHP 8.4, pronta da sostituire integralmente al file originale.

🧹 Cosa risolve questa versione

• ✅ Elimina tutti i warning “Undefined array key feedback_id, score_quality, etc.”

• ✅ Previene “Trying to access array offset on null”

• ✅ Protegge $user_id e l’IP utente da chiavi mancanti

• ✅ Compatibile con PHP 8.4, senza modificare la logica originale

Vuoi che ti preparo anche il patch .diff pronto per patch -p1, così puoi applicarlo direttamente via SSH senza sostituire manualmente il file?

Ottimo, hai individuato tutti i warning principali. Te li riassumo in modo preciso e pratico, con le correzioni da applicare file per file.
Questi sono avvisi PHP 8.4 causati da chiavi o variabili non definite, quindi non bloccano ma sporcano i log e rallentano.

🧾 SITUAZIONE ATTUALE

🧰 CORREZIONI

1️⃣ /oc-content/plugins/listing_status/index.php

Sostituisci le linee 27–28 con:

php
Copia codice
$item_status = $_POST['item_status'] ?? '';
$status_name = $_POST['status_name'] ?? '';

2️⃣ /oc-content/themes/titit/item.php

In tutte le parti dove compare $item['b_company']
(come linee 51, 53, 206, 210), cambia in:

php
Copia codice
$b_company = $item['b_company'] ?? '';

oppure se viene usato direttamente dentro echo, usa:

php
Copia codice
echo $item['b_company'] ?? '';

3️⃣ /oc-content/plugins/profile_picture/index.php (linea 203)

Aggiungi prima di quella linea:

php
Copia codice
$height = $height ?? 100; // default height

oppure, se serve evitare effetto visivo, metti null:

php
Copia codice
$height = $height ?? null;

4️⃣ /oc-content/plugins/backoffice_manager/form/form_feedback_add.php

(Linee 106–117, riferite ai dati utente)

Aggiungi in cima al file o subito prima dell’uso di $user:

php
Copia codice
$user['s_name']      = $user['s_name']      ?? '';
$user['dt_reg_date'] = $user['dt_reg_date'] ?? '';
$user['s_country']   = $user['s_country']   ?? '';
$user['s_region']    = $user['s_region']    ?? '';
$user['s_city']      = $user['s_city']      ?? '';

🧩 IN BREVE

Vuoi che ti preparo un mini script bash che applica automaticamente tutte queste correzioni (backup + sed patch) nei file?
Così puoi eseguirlo su /var/www/au/ e risolvi in un colpo solo.

Perfetto — qui il problema è chiarissimo: gli Undefined array key "item_status" e "status_name" derivano proprio da questo file.
PHP 8.4 ora non consente più di accedere a chiavi non definite negli array senza l’operatore ??, quindi dobbiamo rendere il codice “safe”.

Ecco la versione corretta e compatibile con PHP 8.4, senza alterare la logica originale:

🧩 Cosa risolve questa versione

• ✅ Evita warning Undefined array key "item_status" e "status_name"

• ✅ Evita warning se getStatusByItemId() o getStatusName() ritornano null

• ✅ Usa osc_esc_html() per sicurezza XSS

• ✅ Mantiene piena compatibilità con PHP 8.4

Vuoi che ti prepari anche la versione .diff pronta da applicare via patch (per aggiornare direttamente senza sovrascrivere manualmente)?

Perfetto — questo è il file item.php del tema titit, quello che nei log generava:

pgsql
Copia codice
Undefined array key "b_company" in item.php on line 51, 53, 206, 210

Vediamo come correggerlo senza toccare la logica, ma rendendolo PHP 8.4-safe.

🔧 Problema

Le righe come queste:

php
Copia codice
$user = User::newInstance()->findByPrimaryKey(osc_user_id());
if ($user['b_company'] == '0') {
    ...
} else if ($user['b_company'] == '1') {
    ...
}

assumono che $user['b_company'] esista sempre, ma se $user è null o la chiave non esiste → warning.

✅ Correzione consigliata

Cerca i due blocchi nel file:

1️⃣ Prima sezione (intorno alle linee 200 ca):

Sostituisci:

php
Copia codice
$user = User::newInstance()->findByPrimaryKey(osc_user_id());
if ($user['b_company'] == '0') {
    echo __('Personal', 'titit');
} else if ($user['b_company'] == '1') {
    osc_run_hook('dealer_page_link', osc_item_user_id());
} else {
    echo __('Unregistered user', 'titit');
}

con:

php
Copia codice
$user = User::newInstance()->findByPrimaryKey(osc_user_id()) ?? [];
$b_company = $user['b_company'] ?? null;

if ($b_company === '0') {
    echo __('Personal', 'titit');
} elseif ($b_company === '1') {
    osc_run_hook('dealer_page_link', osc_item_user_id());
} else {
    echo __('Unregistered user', 'titit');
}

2️⃣ Seconda sezione (intorno a riga 600 ca, dentro <div id="c-seller">):

Sostituisci:

php
Copia codice
$user = User::newInstance()->findByPrimaryKey(osc_user_id());
if ($user['b_company'] == '0') {
    ...
} else if ($user['b_company'] == '1') {
    ...
} else {
    echo __('Unregistered user', 'titit');
}

con:

php
Copia codice
$user = User::newInstance()->findByPrimaryKey(osc_user_id()) ?? [];
$b_company = $user['b_company'] ?? null;

if ($b_company === '0') {
    echo '<a href="' . osc_user_public_profile_url(osc_item_user_id()) . '" title="' . __('Check profile of this user', 'titit') . '">';
    profile_picture_show(null, null, 53);
    echo '</a>';
} elseif ($b_company === '1') {
    echo '<a href="' . dd_dealer_public_profile_url(osc_item_user_id()) . '" title="' . __('Check profile of this user', 'titit') . '">';
    profile_picture_show(null, null, 53);
    echo '</a>';
} else {
    echo __('Unregistered user', 'titit');
}

🔒 Risultato

• Nessun warning “Undefined array key b_company”

• Stesso comportamento visivo e funzionale

• Compatibile con PHP 8.4 e future versioni

Vuoi che ti generi un piccolo patch .diff pronto da applicare via SSH (patch -p1 < fix-item.diff) per queste due sezioni?

Perfetto 👍
Ecco il file /oc-content/themes/titit/item.php completo, già corretto e reso PHP 8.4-safe, con tutte le variabili e chiavi di array controllate (b_company, user, ecc.).
Non cambia nulla nel comportamento o nel layout, ma elimina definitivamente i warning dai log Apache.

🧩 Modifiche principali

• Tutte le occorrenze di $user['b_company'] → protette con $user = … ?? []; $b_company = $user['b_company'] ?? null;

• Nessun warning se $user è null o non ha la chiave.

• Nessun cambiamento estetico o logico.

Vuoi che ti includa l’intero file completo con anche la parte finale del box venditore (quella che hai incollato dopo riga 600), tutta aggiornata e già formattata per copia-incolla pronta?
Posso fornirla completa fino a </html>.

Perfetto.
Qui sotto trovi il file completo item.php del tema titit, già corretto per PHP 8.4 — tutti gli accessi a chiavi di array (b_company, ecc.) e variabili ($height) sono stati messi in sicurezza, ma senza alterare alcun comportamento né visivo né funzionale del sito.

🔍 Cosa cambia

• Tutti i riferimenti a $user['b_company'] sono ora protetti da:

  php
  Copia codice
  $user = User::newInstance()->findByPrimaryKey(osc_user_id()) ?? [];
  $b_company = $user['b_company'] ?? null;
  

• Nessun “Undefined array key” nei log.

• Nessun effetto sul layout o sulle funzioni Osclass.
