Lo script php di seguito elabora dati, campi di testo, due caricamenti di file. Lo script ha due istruzioni sql, in firefox 33.1, questo script funziona interamente. Script non funziona in Safari per Windows 5.1.7 o IE 11. In particolare, è la seconda istruzione SQL che non è in esecuzione in entrambi i Saf o IECause comuni dei problemi lato server durante l'utilizzo di safari e IE
$sql="UPDATE listings SET listing_img='$listing_img' WHERE id=$this->id"'
Questa affermazione tira $ this-> id da al di fuori della classe, quindi chiedendosi se questo potrebbe essere il problema?
Safari 5.1.7 restituisce true per il caso UPLOAD_ERR_NO_FILE: (line207), tuttavia non è vero, il file è stato caricato.
È possibile? Perché un browser dovrebbe avere qualche relazione con qualcosa sul lato server?
devo cercare nel file js per i problemi qui o potrebbe essere il bug qui nel file php altrettanto bene
Esistono cause più comuni di safari e la compatibilità di IE per PHP in questo momento?
Conosco un sacco di domande, una sceneggiatura ridicolmente lunga, non le migliori domande ma sono perso qui. qual è il prossimo passo logico per risolvere questo problema?

I browser non si interfacciano direttamente con il server. Stai usando ajax o qualcosa del genere? – Ohgodwhy
Sto usando ajax! – rhill45
puoi descrivere in modo più dettagliato "Script non funziona in Safari o IE"? cioè messaggi di errore del server, codice HTTP, quanto tempo è stata eseguita la richiesta prima di ottenere quel risultato nei casi riusciti e non riusciti (vedere gli strumenti dev di browser network inspector) ecc ... – Calimero
