Can you please post the updated code? From what I can tell about the code you've posted, you don't have $limit defined.
-
Are you echoing the variable?
-
You'll need to have a table that has each individual sessions in it, and the script will need to update the database every time a user goes to another page with the page name and the time.
-
Put:
if(isset($_POST['send']))
in place of if($_GET['send'])
-
Try using htmlentities() also.
-
"Edit" -> "Go to". I think.
Or, use another notepad.
Google Programmer's Notepad 2
or
Notepad++

<?php header("Content-type: text/css"); ?> /* Rest of your CSS stuff goes here*/ body { background-color: <?php echo $bgcolor; ?> }Save it as something.php and you can call it from another file. That way, you can put variables into external stylesheets.
<html> <head> <link href="something.php" rel="stylesheet" type="text/css" /> </head> </html>
-
Oh right so you can add PHP/Variable into stylesheets?
Thats excellent! Thanks I can add a lot of customisation using that method!
Thanks
Only stylesheets that are embedded in .php files. NOT external stylesheets.
-
Or you could just embed stylesheets into PHP documents
Ex:
<html> <head> <title>Style</title> <style type="text/css"> body { background-color: <?php echo $bgcolor; ?> } </style> </head> <body> Hi </body> </html> -
Of course. Make sure you have different stylesheets for PHP to pick. After all, you can't put variables into stylesheets.
-
No problem. If you get stuck on any part of your code, post the relevant part of the code, and we'll be glad to help.
-
I believed you answered your own question. Let a user submit the color of the page into a database (a simple script should work that part out). Then, whenever that page loads, do a query on the database, and do a simple if/else statement to select the right stylesheet.
-
Use these two functions on all of your variables ($_POST and $_GET):
addslashes() and htmlentities()
If you expect a variable to be a number, use the function is_numeric()
If the script throws an error when a variable is empty, use the function empty()
-
Yes. Thanks.
-
Oh, I should've added that it's for localhost. Sorry about that.

Does anyone know of a good, reliable mail client that works with WAMP? I only need a client that can send e-mails (don't need to receive them - need it for websites that I design to send out activation e-mails). Thanks.
-
If it is solved then that's a neat trick.
It's Jan 6th, 2008 and I'm 58.
But I could have become 58 today or I might become 59 tomorrow.
So all you know is that I was born sometime between Jan 7th 1949 and Jan 6th 1950
Yes, I'm aware of that fact. Just knowing how old someone is doesn't give you the exact birthdate.
-
In your original code, I don't see an else statement anywhere. I see an elseif statement, though.
-
<?php $webarray = array("http://www.site1.com", "http://www.site2.com", "http://www.site3.com", "http://www.site4.com" ); $rand = rand(0,sizeof($webarray)); header( 'Location: '.$webarray[$rand]) ; ?> -
Ok, thank you both of you. I believe I got it.

The mysql manual contains an AGE calculation example -
http://dev.mysql.com/doc/refman/5.0/en/date-calculations.html
Thanks for the link.
Depending on php version and operating system, a UNIX timestamp cannot be used for ages because it cannot represent dates before 1970.
Hm, then what would be a better way to store date of births?
Well with the WHERE clause, what column are you using?
The logic is: select users from the users table where the user's age is greater than (or equal to) time() minus $age1 and less than (or equal to) time() minus $age2. Right?
That wouldn't be it because I have date of births stored in the database, not ages.
-
Hm... I'm not very familiar with doing math inside queries... will it be something like this? (Assuming that "dob" is the field name and
$age1
and
$age2
are the submitted ages)
<?php $query = 'SELECT * FROM users WHERE ' . time() . ' - dob > ' . $age1 . ' AND ' . time() . ' - dob < ' . $age2; ?>
-
So that means I'll have to first SELECT every record from the database and check each record using your method?
-
First of all, I've scoured Google, but they only gave me how to calculate age by given birth. I need the opposite.
So, here's the thing. I have a pretty simple site that has the basic user database, and a search engine. When a user registers, their date of birth (that they have provided) is converted into a UNIX timestamp and is stored in the database. Now, the search engine is designed so that a user can give a range of ages to search for (ex: can find all users between the ages of 18 to 30). Since I have users' date of birth stored in the database, not their ages, how will I design the script to work?
Will converting the given ages to UNIX timestamps first, then using MySQL's "<" and ">" operators to search the database work? Or is there a different way?

Uh oh. Try looking at the file list now in the account that you gave us. Better fix somethings. (I just typed in "><script>" (without quotes)
