Requesting NAME OF FORM by php -

संभव डुप्लिकेट:

मेरे पास कोई कैप्चा नहीं है और यह POST विधि द्वारा सबमिट कर रहा है। मैं स्पैमिंग के लिए डर रहा हूं। उपयोगकर्ता एजेक्स द्वारा अपना डेटाबेस स्पैम कर सकता है I मैं इसे स्पैमरों द्वारा कैसे सुरक्षित करूँगा.एनी विचार .. अग्रिम धन्यवाद ..

एक सरल अतिरिक्त क्षेत्र का उपयोग करें ।

जैसे कुछ पूछें: 2 + 3 =

और सत्यापित करें कि मान 5 का उपयोग करके PHP है।

इसकी एक बहुत सरल कैप्चा है, लेकिन इसकी तुलना में बेहतर है कुछ भी तो नहीं। आसानी से टूट सकता है।

I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do.
