siteurl WordPress come cambiarla?

[GrG]

Ho un problema:

dovrei mettere due siti wordpress su server divers, ma con un db unico:

funziona tutto perfettamente, ma ho un problema: wordpress si prende l'url del sito attraverso il db mysql.

senza andare a modificare uno per uno i file che lo usano come posso farli recuperare qulla variabile dal config.php?

[andrea.paiola]

ma devono avere in comune le tabelle sul db? mi pare strano

[NikyAT1]

Amministraione -> Opzioni.
Non mi sembra così difficile. Forse non ho capito...

Si, ma non vi posso dire il motivo perchè vi mettereste a ridere;

X Niky

No, non è quello


Cerco di spiegare + velocemente:

Allora, wordpress ha l'url del sito inserito nel db; Tutti gli url delle pagine vengono creati con $siteurl/pagina

Io devo collegare due blog allo stesso db, stesse tabelle; I due blog logicamente hanno link diverso quindi la variabile non può essere una e devo ovviare a questo

A questo punto la cosa più semplice penso sia beccare dove WP prende quella variabile (in che pagina .php) e modificarlo per fargliela recuperare da un file (in quel modo metto un file in ognuno dei due siti e risolvo)

Il problema principale è che non conosco il php...

A logica dovrebbe essere in un file tipo classes.php che poi viene incluso dagli altri, ecco quindi le pagine partendo da zero
