bkit po nag method call ka?wala ka namn constructor sa cal na method kuya.at pwd mo namn mapa.simple yan

Futility · Jul 15, 2017

I-echo mo na lang nang rekta yung $result ts.
Tsaka yung calculator(), method ba yan o class?

Isa pang trivial thing. Walang html tags sa umpisa pati closing.

ok na ts ung sa html file nalang,, dapat ung result kasama padin ng mga forms,, ang nangyayare kasi parang narerefresh tas ung sagot lang napiprint

Futility · Jul 15, 2017

Ganito kasi nangyayari kapag nagsusubmit ng forms sa PHP.

Diba merong action na attribute sa form.
Yung value ng attribute na yun ang pupuntahan ng browser mo, kasama yung mga data na sinubmit mo sa mga input tags.

Since isa lang yung output mo(echo), yun lang ang nadidisplay, which is yung sagot sa operation.

Pwede yan maging workaround sa problem mo po.
Hindi kasi maiiwasang magrefresh niyan kasi nagreredirect yan sa PHP file mo.

Silipin niyo po kung paano ang AJAX, medyo advanced lang siya, pero yan ang solusyon kung gusto mo po na hindi na ma-refresh ang whole page, yung part lang ng page.

Off topic lang din po, ikaw po yung ts dito sa thread.
TS = Thread Starter
