mySQL i php u DRW mxProblem je mozda prost ali ja ga ne mogu resiti...
Naime, kako da nateram mysql da sabira??!Iz php forme (tj.HTML) ubacujem dve varijable ili vise nebitno i one se pamte u bazu u tabeli tb_a(recimo) u tabeli imam 4 polja id;varA;varB i sumu( A+B) a tu je i problem to nikako nece da se desava sa mojim slucajem probao sam sa ovim ali mi neide ,da li postoji drugo resenje
Code:
<form action="" method="post" name="form1">
<p>
<input name="vred_a" type="text" id="vred_a">
</p>
<p>Unesi B </p>
<p>
<input name="vred_b" type="text" id="vred_b">
</p>
<?php
$vr_a = "FORM1.vred_a";
$vr_b = "FORM1.vred_b";
function Suma(){
$GLOBALS["vr_s"] = $GLOBALS["vr_a"]+ $GLOBALS["vr_b"];
}
Suma();
$_POST ['vr_s'];
?>
<p>
<input type="submit" name="Submit" value="Submit">
</p>
</form>
<form action="" method="post" name="form1">
<p>
<input name="vred_a" type="text" id="vred_a">
</p>
<p>Unesi B </p>
<p>
<input name="vred_b" type="text" id="vred_b">
</p>
<?php
$vr_a = "FORM1.vred_a";
$vr_b = "FORM1.vred_b";
function Suma(){
$GLOBALS["vr_s"] = $GLOBALS["vr_a"]+ $GLOBALS["vr_b"];
}
Suma();
$_POST ['vr_s'];
?>
<p>
<input type="submit" name="Submit" value="Submit">
</p>
</form>
Takodje sam probao sa query-jem iz dreamW tj Recordset >> Advanced pa tamo
SELECT vrednost_a + vrednost_b AS suma_i ....
Ali ni to ne pali izracunava samo prvi slog u tabeli tj. id=1?
