    awesome...thanks
  2. helpmehelpmehelpme
    okay, it looks like they all work except for the background color and the link color.
  3. helpmehelpmehelpme
    i have this example, but im not sure how to do it for the background color and the others, if (isset($_COOKIE['font_color'])) { print "\t\tcolor: #" . htmlentities($_COOKIE['font_color']) . ";\n"; } else { print "\t\tcolor: #000;"; }
  4. helpmehelpmehelpme
    it still doesn't work, but could you do an if statement. like if the user selects whatever color from the drop down list, change the styles color or something like that
  5. helpmehelpmehelpme
    no errors this time, but it's still not changing the styles on the page. The background is white, it should change when the user selects a color and goes to file3
  6. helpmehelpmehelpme
    like this? <style type="text/css"> <!-- These are the styles the session should configure --> a:link {color:#<? $_COOKIE['link_color']; ?>} //Use the variable in the style a:hover {color:#<? $_COOKIE['link_hover_color']; ?>} body {background-color:#<? $_COOKIE['background_color']; ?>} h1 {color:#<? $_COOKIE['header_color']; ?> text-align:center;} </style> it still doesnt change the styles on the page....im confused
  7. helpmehelpmehelpme
    sorry, file 2 returned that but when you click click here to see it in action which goes to file3, it says Notice: Undefined index: background_color in C:\xampp\htdocs\xampp\PHP\file3.php on line 10 Notice: Undefined index: link_color in C:\xampp\htdocs\xampp\PHP\file3.php on line 11 Notice: Undefined index: link_hover_color in C:\xampp\htdocs\xampp\PHP\file3.php on line 12 Notice: Undefined index: header_color in C:\xampp\htdocs\xampp\PHP\file3.php on line 13 Welcome to YOUR pretty website Click here to go back and start over! and the original styles are displayed
  8. helpmehelpmehelpme
    I tried that instead of it applying the changes to the styles, it prints returns \body: #c00\a:link: #00f Your settings have been updated. Click here to continue. on the page. I don't know, there must be an error somewhere heres the updated code file1.php <?php //Handle the form if it has been submitted: if (isset($_POST['background_color'], $_POST['link_color'], $_POST['link_hover_color'], $_POST['header_color'])){ //send the cookies: setcookie('background_color', $_POST['background_color'], time()+10000000); setcookie('link_color', $_POST['link_color'], time()+10000000); setcookie('link_hover_color', $_POST['link_hover_color'], time()+10000000); setcookie('header_color', $_POST['header_color'], time()+10000000); //Message to be printed later: $msg = '<p>Your settings have been entered!

    I'm trying to write a script that allows the user to select their personal settings for the site. They can pick the color of their background, link color, link hover color and the header color. the first file is supposed to use the defaults, blue for the links, orange for the link hover color red for the background and blue for the header. the second file is supposed to configure the cookie variables to store the values entered by the user and the third file i'm supposed to modify the internal stylesheet to utilize the values stored in the session variables. I tried to set each of the values in file two but i think i messed it up. I dont know how to modify the stylesheet to accept and change to the values of the cookies...Please help here are the files file1.php <?php //Handle the form if it has been submitted: if (isset($_POST['background_color'], $_POST['link_color'], $_POST['link_hover_color'], $_POST['header_color'])){ //send the cookies: setcookie('background_color', $_POST['background_color'], time()+10000000); setcookie('link_color', $_POST['link_color'], time()+10000000); setcookie('link_hover_color', $_POST['link_hover_color'], time()+10000000); setcookie('header_color', $_POST['header_color'], time()=10000000); //Message to be printed later: $msg = '<p>Your settings have been entered!

  12. helpmehelpmehelpme
    now it prints out the users age, but it won't increment by 3s
  13. helpmehelpmehelpme
    okay, now it prints out $age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age$age infinitely
  14. helpmehelpmehelpme
    right, but i keep getting error messages $age Notice: Use of undefined constant i - assumed 'i' in C:\xampp\htdocs\xampp\PHP\test1.php on line 38 $age Notice: Use of undefined constant i - assumed 'i' in C:\xampp\htdocs\xampp\PHP\test1.php on line 38 $age Notice: Use of undefined constant i - assumed 'i' in C:\xampp\htdocs\xampp\PHP\test1.php on line 38 $age Notice: Use of undefined constant i - assumed 'i' in C:\xampp\htdocs\xampp\PHP\test1.php on line 38 $age Notice: Use of undefined constant i - assumed 'i' in C:\xampp\htdocs\xampp\PHP\test1.php on line 38 $age
  15. helpmehelpmehelpme
    I have this script that asks the user their name and email address and age and stuff and it checks to see what their age is and outputs a message depending on what age bracket they belong to. I am trying to make a for loop that uses the value the user submitted for their age and output the range of numbers from the users age to 1000 by 3s, i know how the basic for loop works, but i don't know how to do one where you are using a variable for i. if that makes sense.

  20. helpmehelpmehelpme

  21. helpmehelpmehelpme
    i need one where the user can enter the names themselves and have it cycle through and print out the initials of all the names the user has entered...
  22. helpmehelpmehelpme
    If you had a function that calculated the average of a fixed quantity of numbers, what type of scope issues would you anticipate?
  23. helpmehelpmehelpme
    can you do like a loop or something that would let the user enter like 5 other names and have it print out all of the initials?
  24. helpmehelpmehelpme
    oh duh, i was thinking you had to do the $_POST up in the function somewhere...thanks for your help..
  25. helpmehelpmehelpme
    okay, I have index.php <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Functions!</title> </head> <body> <p>Please enter your first and last name so I can give you your initials.</p> <form action="functions.php" method="post"> <p>First Name: <input type="text" name="first_name" size="20" /></p> <p>Last Name: <input type="text" name="last_name" size="20" /></p> <input type="submit" name="submit" value="Get My Initials" /> </form> </body> </html> and function.php <?php function first_and_last($first_name, $last_name ) { return $first_name[0] . '. ' . $last_name[0] . '.'; } ?> if i'm posting $first_name and $last_name from the index.php page to the functions.php page where would I put the $_POST? or how would i write it into the code
