pie title Module Installation Failure Causes
"Permission Issues" : 30
"Missing xoopsversion.php" : 20
"Database SQL Errors" : 20
"Corrupted Upload" : 15
"PHP Version Incompatibility" : 10
"Directory Already Exists" : 5

Symptome:

  • Upload schlägt mit “Permission denied” fehl
  • Modul-Ordner nicht erstellt
  • Kann nicht in modules-Verzeichnis schreiben

Fehlermeldungen:

Warning: move_uploaded_file(): Unable to move file
Permission denied (13)

Lösungen:

Terminal-Fenster
# Check current permissions
ls -ld /path/to/xoops/modules
ls -ld /path/to/xoops/uploads
# Fix module directory permissions
chmod 755 /path/to/xoops/modules
# Fix temporary upload directory
chmod 777 /path/to/xoops/uploads
chmod 777 /tmp # if needed
# Fix ownership (if running as different user)
chown -R www-data:www-data /path/to/xoops/modules
chown -R www-data:www-data /path/to/xoops/uploads

Symptome:

  • Modul erscheint in Liste, wird aber nicht aktiviert
  • Installation startet, stoppt dann
  • Keine Admin-Seite erstellt

Fehler in xoops_log:

Module xoopsversion.php not found

Lösungen:

Überprüfen Sie die Modul-Paketstruktur:

Terminal-Fenster
# Extract and check module contents
unzip module.zip
ls -la mymodule/
# Must contain:
# - xoopsversion.php
# - language/
# - sql/
# - admin/ (optional but recommended)

Gültige xoopsversion.php-Struktur:

<?php
$modversion['name'] = 'My Module';
$modversion['version'] = '1.0.0';
$modversion['description'] = 'Module description';
$modversion['author'] = 'Author Name';
$modversion['author_mail'] = 'author@example.com';
$modversion['author_website_url'] = 'https://example.com';
$modversion['credits'] = 'Credits';
$modversion['license'] = 'GPL 2.0 or later';
$modversion['official'] = 0;
$modversion['image'] = 'images/icon.png';
$modversion['dirname'] = basename(__DIR__);
$modversion['modpath'] = __DIR__;
// Core module info
$modversion['hasMain'] = 1;
$modversion['hasAdmin'] = 1;
$modversion['hasSearch'] = 0;
$modversion['hasNotification'] = 0;
// Database tables
$modversion['sqlfile']['mysql'] = 'sql/mysql.sql';
$modversion['tables'] = ['table_name'];

Symptome:

  • Upload erfolgreich, aber Datenbanktabellen nicht erstellt
  • Admin-Seite wird nicht geladen
  • “Table doesn’t exist” Fehler

Fehlermeldungen:

SQL Error: Table 'xoops_module_table' already exists
Syntax error in SQL statement

Lösungen:

Terminal-Fenster
# View the SQL file
cat modules/mymodule/sql/mysql.sql
# Check for syntax issues
# Verify:
# - All CREATE TABLE statements end with ;
# - Proper backticks for identifiers
# - Valid field types (INT, VARCHAR, TEXT, etc.)

Korrektes SQL-Format:

CREATE TABLE `xoops_module_table` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`name` VARCHAR(255) NOT NULL,
`description` TEXT,
`created` INT(11) NOT NULL,
`updated` INT(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
modules/mymodule/test_sql.php
<?php
require_once '../../mainfile.php';
$sql_file = __DIR__ . '/sql/mysql.sql';
$sql_content = file_get_contents($sql_file);
// Split statements
$statements = array_filter(array_map('trim', explode(';', $sql_content)));
foreach ($statements as $statement) {
if (empty($statement)) continue;
try {
$GLOBALS['xoopsDB']->query($statement);
echo "✓ Executed: " . substr($statement, 0, 50) . "...<br>";
} catch (Exception $e) {
echo "✗ Error: " . $e->getMessage() . "<br>";
echo "Statement: " . substr($statement, 0, 100) . "...<br>";
}
}
?>

Symptome:

  • Dateien teilweise hochgeladen
  • Zufällige .php-Dateien fehlen
  • Modul wird nach Installation instabil

Lösungen:

Terminal-Fenster
# Re-upload fresh copy
rm -rf /path/to/xoops/modules/mymodule
# Verify checksum if provided
md5sum -c mymodule.md5
# Verify archive integrity before extract
unzip -t mymodule.zip
# Extract to temp, verify, then move
unzip -d /tmp mymodule.zip
find /tmp/mymodule -name "*.php" | wc -l
# Should show expected number of files

Symptome:

  • Installation schlägt sofort fehl
  • Parse-Fehler in xoopsversion.php
  • “Unexpected token” Fehler

Fehlermeldungen:

Parse error: syntax error, unexpected 'fn' (T_FN)

Lösungen:

Terminal-Fenster
# Check XOOPS supported PHP version
grep -r "php_require" /path/to/xoops/
# Check module requirements
grep -i "php\|version" modules/mymodule/xoopsversion.php
# Check PHP version on server
php --version

Testen Sie die Modul-Kompatibilität:

<?php
// Create modules/mymodule/check_compat.php
$required_php = '7.4.0';
$current_php = PHP_VERSION;
echo "Required PHP: $required_php<br>";
echo "Current PHP: $current_php<br>";
if (version_compare(PHP_VERSION, $required_php, '<')) {
echo "✗ PHP version too old<br>";
} else {
echo "✓ PHP version compatible<br>";
}
// Check required extensions
$required_ext = ['mysqli', 'json', 'mb_string'];
foreach ($required_ext as $ext) {
echo extension_loaded($ext) ? "" : "";
echo " $ext<br>";
}
?>

Symptome:

  • Installation schlägt fehl, wenn Modul-Verzeichnis existiert
  • Kann Modul nicht neu installieren oder aktualisieren
  • “Directory exists” Fehler

Fehlermeldungen:

The specified directory already exists

Lösungen:

Terminal-Fenster
# Backup existing module
cp -r modules/mymodule modules/mymodule.backup
# Remove old installation completely
rm -rf modules/mymodule
# Clear any cache related to module
rm -rf xoops_data/caches/*
# Now retry installation through admin panel

Symptome:

  • Modul wird installiert, aber Admin-Seite fehlt
  • Admin-Panel zeigt Modul nicht
  • Kann auf Modul-Einstellungen nicht zugreifen

Lösungen:

<?php
// Create modules/mymodule/admin/index.php
<?php
/**
* Module Administration Index
*/
include_once XOOPS_ROOT_PATH . '/kernel/module.php';
if (!is_object($xoopsModule) || !is_object($xoopsUser) || !$xoopsUser->isAdmin($xoopsModule->mid())) {
exit("Access Denied");
}
// Include admin header
xoops_cp_header();
// Add admin content
echo "<h1>Module Administration</h1>";
echo "<p>Welcome to module administration</p>";
// Include admin footer
xoops_cp_footer();
?>

Symptome:

  • Modul zeigt Variablennamen statt Text
  • Admin-Seiten zeigen “[LANG_CONSTANT]“-Stil Text
  • Installation abgeschlossen, aber Interface kaputt

Lösungen:

Terminal-Fenster
# Verify language file structure
ls -la modules/mymodule/language/
# Should contain:
# english/ (at minimum)
# admin.php
# index.php
# modinfo.php

Erstelle Sprach-Datei:

modules/mymodule/language/english/index.php
<?php
<?php
define('_AM_MYMODULE_INSTALLED', 'Module installed successfully');
define('_AM_MYMODULE_UPDATED', 'Module updated successfully');
define('_AM_MYMODULE_ERROR', 'An error occurred');
?>

  1. Sichern Sie immer vor der Installation neuer Module
  2. Testen Sie lokal bevor Sie in Production deployen
  3. Überprüfen Sie die Modul-Struktur vor dem Upload
  4. Überprüfen Sie Berechtigungen unmittelbar nach dem Upload
  5. Überprüfen Sie die xoops_log-Tabelle auf Installationsfehler
  6. Behalten Sie Backups von funktionierenden Modul-Versionen
