I tried doing this, and it didnt work. Im goign to identify the $css in the else of an if else statement; so when its else, it willl turn the web page that color, but i cant figure out how to acomplish it.

$css = "<style type="text/css">
body {
background -color: #ffoocc;
}";

you need to escape the " in the css/html. example:

$css = "<style type="text/css">
body {
background -color: #ffoocc;
}";

should be

$css = "<style type=\"text/css\">
body {
background -color: #ffoocc;
}";

You could also use the heredoc syntax

$css =<<<CSS
<style type="text/css">
body {
background -color: #ffoocc;
}
CSS;

there can be NO whitespace in front of CSS;

ok cool that worked but it didnt execute that css code it just came up as $css and i tried it with " " and ' ' didnt make a defrence then i tried just putting $css in the else statement didnt work here is my hole coding

you can't use variables in string using single quotes. you have to use double quotes.
ex.

else {  print '<p> taco is greater </p> $css';}

should be

else {  print "<p> taco is greater </p> {$css}";}

or use concatenation (don't know how its spelled)

else {  print '<p> taco is greater </p> '.$css;}

tecknikly actually there is a space before and after the "-" i just messed up a bit ll didnt fix it though im preaty shure that santax errors arnt causing the problem

try this, i fixed the errors.

oh hmm the book i have now i cant tell if it sais space or not the font is a bit funky hmm i guess there isnt a space but i mean by the loks of this it seems like it could be bouth so idk

is $taco greater than $pizza? everything is correct now. view the source of the page and make sure everything is echoing properly.

also, i just noticed that you forgot your closing </style> .

if ( $pizza > $taco ) {
    echo '<p> pizza is greater </p>';
}
else {
    echo "<p> taco is greater </p> {$css}";
}

?>

hmm yeah it is um do you think it could have something to do with the doctype?

actually maybe. the doctype was typed wrong.

try this. i have no idea why its not working.

<?php

if ( isset( $_POST['submit'] ) ) {
    $pizza = $_POST['pizza'];
    $taco  = $_POST['taco'];
    $showCSS = false;
    if ( $pizza < $taco ) {
        $showCSS = true;
    }
}
else {
    die( 'Nothing submitted' );
}

?>

ohhhh i just figured it out the color was wrong for somreason that color dosent work but when i typed #e2edff if worked cheers mate thank you for all your help also what does the !important mean ?

!important makes sure that color will override any previous body color set earlier in the page. i don't think its need, but I added just to avoid some problems.

its actually ff00cc not ffoocc :)

that would help. i didn't notice those weren't numbers.

make sure you mark the thread as solved.

make sure you mark the thread as solved.

oh yeah i was just going to ask about that how do i do that again its been awhile sence i been here
