Undefined variable: show_errors in

Daredevil · 16. Juni 2017

Hallo Liebe Community ,

ich habe ein Problem mit PHP hier der Code:

class database

{

var $connection = '';

var $db = array ();

var $result = '';

var $show_errors = null;

function database ($host, $name, $user, $pass)

{

$this->db['host'] = $host;

$this->db['name'] = $name;

$this->db['user'] = $user;

$this->db['pass'] = $pass;

$this->show_errors = $show_errors; /* diese Zeile macht die Probleme */

}

hier ist die Fehlermeldung :

Undefined variable: show_errors in

ich hoffe ihr könnt mir helfen

Die variable $show_errors ist nicht gesetzt.

Die kommt nicht in die Methode, und Du setzt sie auch nicht.

Woher kommt, oder soll denn der Wert kommen?

Wenn von außen, dann brauchst Du einen zusätzlichen Parameter wie zB

PHP

 function database ($host, $name, $user, $pass, $show_errors)

oder besser noch Du setzt den Wert über eine eigene Methode (einen "setter"):

PHP

class database
{
    var $connection = '';
    var $db = array();
    var $result = '';
    var $show_errors = null;

    function database($host, $name, $user, $pass)
    {
        $this->db['host'] = $host;
        $this->db['name'] = $name;
        $this->db['user'] = $user;
        $this->db['pass'] = $pass;
    }

    public function setShowErrors($bool)
    {
        $this->show_errors = (bool)$bool;
    }
}

Danke für die schnelle Rückantwort doch leider funktioniert es nicht.

cottton · 16. Juni 2017

Was funktioniert nicht?

Gibts ne Fehlermeldung?

Wie sieht der Code jetzt aus?

Daredevil · 16. Juni 2017

ich habe den 2 Code von dir übernommen und eingefügt doch leider ist es die selbe Fehlermeldung :

Undefined variable: show_errors in <b>G:\xampp\htdocs\surfzentrale\lib\database.class.php

cottton · 16. Juni 2017

Das kann nicht sein. Denn in meinem 2ten Bsp Code gibt the keine Nutzung der Varibale

Zeig doch nochmal den code. Ich meine, ich kann ja raten, aber das dauert dann länger :p

so dein Code funktioniert zwar doch da stimmt was nicht :

ich werde jetzt mal die Dateien Posten die zusammengehören und auch mit require_once eingebunden sind.
