well @#$%^&*(.

I have the hardest time spotting my own errors.... I'm writing some CSS that depends on PHP. This is the php created css... <?php if (isset($_POST['submitted'])){ //variables from form $bars2 = $_POST['stages']; $first2 = $_POST['first']; $last2 = $_POST['last']; //Separate the rgb values $fv = explode(",","$first"); $lv = explode(",","$last"); //Do some math to figure out the step value $n = ($bars - 1); $j1 = (($lv["0"] - $fv["0"])/$n); $j2 = (($lv["1"] - $fv["1"])/$n); $j3 = (($lv["2"] - $fv["2"])/$n); //Variables and math. $step = ($bars2 - 2); $l = "0"; $w = (100 / $bars2); $r = $fv["0"]; $g = $fv["1"]; $b = $fv["2"]; // gerneral div CSS echo "div { position: absolute; top: 20px; height: 600px; }"; //First bar echo "#start { position: absolute; left: $l%; width: $w%; background-color: rgb($first2); }"; //Middle Bars while ($step != 0){ $r += $j1; $g += $j2; $b += $j3; $l += $w; $r2 = round($r); $g2 = round($g); $b2 = round($b); echo "#$step { position: absolute; left: $l%; width: $w%; background-color: rgb($r2,$g2,$b2); }"; $step -= 1; } $l += $w; //Last bar echo "#end { position: absolute; left: $l%; width: $w%; background-color: rgb($last2); }"; } ?> and this is the php that defines the div elements.. if (isset($_POST['submitted'])) { //variables from form $bars = $_POST['stages']; //Display necessary div tags $div = ($bars - 2); echo '<div id="start"></div>'; while ($div != 0){ echo "<div id='$div'></div>"; $div -= 1; } echo '<div id="end"></div>'; and here is the link of where I'm testing it... http://easlnx01.eas.muohio.edu/~meadecm/tvtest.php Something is not letting the middle bar divs print, and I can't find the error. My loop seems to work because it adds the correct amount of space in the center. Please don't hack me X.X

the program accepts: $p% but not in single quotes ' ', I had to use " "

Neither seems to work. the source code just prints like this: div { position: absolute; top: 20px; height: 600px; width: ".$w."% }

So say I have the variable $p = 10 , and I wanted to use it in css, so I'd need "10%". I've tried echoing it various ways, but nothing reads through the source code. $p% ($p)% '$p'% .... I'm not sure how to type this up. used like this: echo "div { width: $p%; }";

adding quotations worked!

to clear out some of the junk code... // Function to create a uniquely named 20+ color select menu function Selectors ($a){ echo '<select name="$a">'; echo '<option value="127,255,212">Aquamarine</option>'; echo '<option value="0,0,0">Black</option>'; echo '<option value="0,0,255">Blue</option>'; echo '<option value="220,20,60">Crimson</option>'; echo '<option value="0,255,255">Cyan</option>'; echo '<option value="148,0,211">Dark Violet</option>'; echo '<option value="255,20,147">Deep Pink</option>'; echo '<option value="255,215,0">Gold</option>'; echo '<option value="255,0,255">Magenta</option>'; echo '<option value="25,25,112">Midnight Blue</option>'; echo '<option value="255,165,0">Orange</option>'; echo '<option value="128,0,128">Purple</option>'; echo '<option value="255,0,0">Red</option>'; echo '<option value="65,105,255">Royal Blue</option>'; echo '<option value="192,192,192">Silver</option>'; echo '<option value="135,206,235">Sky Blue</option>'; echo '<option value="0,255,127">Spring Green</option>'; echo '<option value="64,224,208">Turquoise</option>'; echo '<option value="238,130,238">Violet</option>'; echo '<option value="255,255,0">Yellow</option>'; echo '</select>'; } // Variables to use when calling the previous function $f = "first"; $l = "last"; //begin html form echo '<form action="tvtest.php" method="POST">'; //Hidden input... echo '<input type="hidden" name="windowWidth" id="windowWidth" />'; echo '<input type="hidden" name="windowHeight" id="windowHeight" />'; // Input table echo '<table>'; echo '<tr>'; echo '<td><label>First Color:</lable></td>'; echo '<td>'; Selectors($f); echo '</td>'; echo '</tr>'; echo '<tr>'; echo '<td><label>Second Color:</lable></td>'; echo '<td>'; Selectors($l); echo '</td>'; echo '</tr>'; echo '<tr>'; echo '<td><label>Number of Stages: </label></td>'; echo '<td><input type="text" name="stages" /></td>'; echo '</tr>'; echo '<tr>'; echo '<td colspan="2">'; echo '<input type="submit" name="submitted" value="Show Pattern" /></td>'; echo '</tr>'; echo '</table>'; echo '</form>'; //End html form and then if (isset($_POST['submitted'])) { $bars = $_POST['stages']; $first = $_POST['first']; $last = $_POST['last']; echo "You entered $bars stage(s). "; echo "Your first color is $first. Your last color is $last.";

When I try to echo the values selected in my select boxes ( $first and $last ) nothing shows up.... I'm wondering if my user created function isn't naming them like I'd like... <html xmlns="http://www/w3c.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Catherine: TV Test</title> <script type="text/javascript"> function load() { var wH = window.innerHeight; var wW = window.innerWidth; document.getElementById('windowWidth').setAttribute('value',wW); document.getElementById('windowHeight').setAttribute('value',wH); } </script> <style type="text/css"> #main { position: relative; height: 100%; margin-left: 20px; margin-right: 20px; } table { position: relative; top: 20px; margin-left: auto; margin-right: auto; text-align: center; } <?php echo '#leftbar { position: absolute; top: 20px; left: 0px; width: 50%; height: 600px; background-color: rgb(0,0,255); }'; ?> </style> </head> <body onload="load()"> <div id="main"> <?php if (isset($_POST['submitted'])) { $bars = $_POST['stages']; $first = $_POST['first']; $last = $_POST['last']; echo "You entered $bars stage(s).

Your last color is $last."; //Gradient display code: // echo '<div id="leftbar"></div>'; } else { /* The two following tags MUST included in a form that YOU design within * this section of PHP code. */ // Function to create a uniquely named 20+ color select menu function Selectors ($a){ echo '<select name="$a">'; echo '<option value="127,255,212">Aquamarine</option>'; echo '<option value="0,0,0">Black</option>'; echo '<option value="0,0,255">Blue</option>'; echo '<option value="220,20,60">Crimson</option>'; echo '<option value="0,255,255">Cyan</option>'; echo '<option value="148,0,211">Dark Violet</option>'; echo '<option value="255,20,147">Deep Pink</option>'; echo '<option value="255,215,0">Gold</option>'; echo '<option value="255,0,255">Magenta</option>'; echo '<option value="25,25,112">Midnight Blue</option>'; echo '<option value="255,165,0">Orange</option>'; echo '<option value="128,0,128">Purple</option>'; echo '<option value="255,0,0">Red</option>'; echo '<option value="65,105,255">Royal Blue</option>'; echo '<option value="192,192,192">Silver</option>'; echo '<option value="135,206,235">Sky Blue</option>'; echo '<option value="0,255,127">Spring Green</option>'; echo '<option value="64,224,208">Turquoise</option>'; echo '<option value="238,130,238">Violet</option>'; echo '<option value="255,255,0">Yellow</option>'; echo '</select>'; } // Variables to use when calling the previous function $f = "first"; $l = "last"; //begin html form echo '<form action="tvtest.php" method="POST">'; //Hidden input... echo '<input type="hidden" name="windowWidth" id="windowWidth" />'; echo '<input type="hidden" name="windowHeight" id="windowHeight" />'; // Input table echo '<table>'; echo '<tr>'; echo '<td><label>First Color:</lable></td>'; echo '<td>'; Selectors($f); echo '</td>'; echo '</tr>'; echo '<tr>'; echo '<td><label>Second Color:</lable></td>'; echo '<td>'; Selectors($l); echo '</td>'; echo '</tr>'; echo '<tr>'; echo '<td><label>Number of Stages: </label></td>'; echo '<td><input type="text" name="stages" /></td>'; echo '</tr>'; echo '<tr>'; echo '<td colspan="2">'; echo '<input type="submit" name="submitted" value="Show Pattern" /></td>'; echo '</tr>'; echo '</table>'; echo '</form>'; //End html form } ?> </div> </body> </html>

OI! It was adding an ^M to the users file, now it works.. kind of

It's formated like... me&123 cat&meow I already changed the "$" in my php to a "&" that was a dumb mistake but it didn't fix anything.

It's just a learning tool, it's not functional.

I know there has to be a better way to do this. My usernames and passwords are stored in a text file. This is what I'm doing now, and all it does is return the error statement. This is the php from after the log in page. <?php $user = $_POST["username"]; $password = $_POST["password"]; $un = "no"; $pw = "no"; $fh = fopen("users.txt","r"); while (!feof($fh)) { $line = fgets($fh); $data = explode("$",$line); if ($data["0"] == $user){ $un = "yes"; } if ($data["1"] == $password){ $pw = "yes"; } } if (($un === "yes") && ($pw === "yes")){ echo "<h4> Hello <em>$user</em>!\n<br />"; }else { echo "<h3>Your username and/or password is incorrect.</h3>\n<br />"; echo "<a href='login.html'>Return to the login page.</a>\n<br />"; } fclose($fh); ?>

ohhh that worked!!

Here's all of it, maybe the error is somewhere else. I added a check that would print the $fw variable, and everything prints as it should, but my webpage is here and not working well http://easlnx01.eas.muohio.edu/~meadecm/project02.php <?php //Returns the first word of a paragraph function getFirstWord($p,$x) { $str = $p[$x]; $word = explode(" ",$str); return $word[0]; } // Opens the constitution text file, writes to a variable, explodes. $data = file_get_contents('constitution.txt'); $paragraphs = explode("&",$data); // Formats the Preamble. echo "<p><em>$paragraphs[0]</em></p>"; // Runs through some if statements to determine the tags to use on remander. $n = 1; do { $fw = getFirstWord($paragraphs,$n); if ($fw == 'Article'){ echo "<h2>$paragraphs[$n]</h2>"; } elseif ($fw == 'Section'){ echo "<h3>$paragraphs[$n]</h3>"; } elseif ($fw == 'Amendment'){ echo "<h3>$paragraphs[$n]</h3>"; } else{ echo "<p>$paragraphs[$n]</p>"; } $n += 1; echo "\$fw=$fw\n"; } while (count($paragraphs) >= $n) ?>

Thank you, that's pretty much what I did... sorryididntknowaboutthis
