[RESOLVED]Multiple IF's

[dandono]

hi, how can i have several IF statements in a statement. if you know vb then it may make more sence as:

If var1 = "something" then
     If var2 = "somethingelse" then
          Do_Something
     End If
End If

does that help? this is like the best i can explain which either makes me stupid or not that good at thinking.
thanks, dandono

if ($var1 == $var2 && $var2 == $var3) {

}

&& = And
|| = Or

That what your after?

If you want it similar to the code you have, i think you can just do:

if($var1 == "hi"){
    if($var2 == "all"){
        // stuff
    }
    // other stuff if you want
}

thanks. i have not been able to figure that one out for the time i have "known" php.

[neicedover1982]

you could also use if/elseif/else statements.

[dandono]

so i could do

If (var1 == "blah")
{
echo "blah";
}elseif(var2 == "blah2")
{
echo "blah2";
} 

[neicedover1982]

Yes, the best format is as follows.

If (var1 == "blah") { 
    echo "blah"; 
} elseif (var2 == "blah2") { 
    echo "blah2";
} else {
    echo "blah3";
} 

You can put as many elseif's as you want, I would suggest you also use the "else" at the end as a "catch all" incase the if statements dont catch whats being passed, kind of like error checking.

I use it and have it post the info its looking at so if I ever see it, I know whats going on.

[dandono]

ok thanks. this will help in a new login script for my website.

[dandono]

i got an error on this line of code:

} 
elseif($admin == "daniel") 
{ 

Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in D:\main\index.php on line 22
i dont know what is wrong. if it helps i can post the whole code but it is 99 lines of code but most of it is html

[dandono]

sorry i fixed it. the problem was that i was echoing a string and it was started with the " type thing and closed with the ' type thing. my brain is a bit slow today and i cant remember what they are called

[PlaGuE]

double "quotes" single 'quotes'

[dandono]

oh yeah

[visualAd]

Try to use single quotes rather than double quotes, unless you want embedded variables and/or escape sequences such as \n in the string.

[dandono]

i normaly use single quotes because if you do something like

echo "<img src="someimg.jpg">"; 

then it thinks the string ends at "src=" and then makes an error but if you did

echo '<img src="someimg.jpg">'; 

then it would work fine.
