[[SOLVED] users logged in]

 

If you use a sessions table, you update the session time in the database everytime a user loads a page. You then log them out if a session update time is a certain amount of time greater than the session start time. Everytime it updates it checks...etc. So it will be as accurate as you can get within a few minutes time.

Sessions table in your MySQL database. That is all. Over & out. :-P

[Meta Refresh not working in IE7]

Why not just use the header function?

<?php

header("location: main.php");

?>

[Using ISSET to set POST Variable to part of Where Statement]

 or die mysql_error());

 

seeing any lopsided parentheses in there?  i do.

 

Good catch.

[Using ISSET to set POST Variable to part of Where Statement]

<?php

$folder_info = mysql_query("SELECT * FROM foldersmain WHERE $folder_column = '$folder_value'") or die mysql_error());

?>

 

Remove the single quotes around the column variable. Try that. Otherwise...is that all the code on the page generating the error?

[mkdir stopped functioning when i changed hosts]

Folder permissions for starters? Lotta times when you upload files it will default to 644/755...in which case, you won't be able to write to the folder you're in.

[[SOLVED] delimiting timestamp queries to show only date, no time]

Hmmmglad you got it. Although if that didn't work..means your "timestamp" isn't really a timestamp. :-) It must be formatted or stored as an actual DATE.

[[SOLVED] delimiting timestamp queries to show only date, no time]

If stored as a timestamp...you don't need to do a whole lot. In fact, works much nicer when it is a timestamp...

 

 

<?php

  $formatstamp = date("M d, Y",$info[time]);

  echo $formatstamp;

?>

 

That's it.

[Persistent form data?]

Be much easier if you processed the form on the same page. You can include the code that does it, if the $_POST array has been set. *SHRUGS*

Things you can do to improve

 

1. Layout/design - Use CSS

2. Take an OOP approach to your script.

[URL ReWrite - MonsterGamez.net]

If you are on a *nix based server that supports POSIX 1003.2 regular-expressions...

 

# Rewrite <subdomain>.example.com/<path> to example.com/<subdomain>/<path>
#
# Skip rewrite if no hostname or if subdomain is www
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\. [NC]
# Extract (required) subdomain (%1), and first path element (%3), discard port number if present (%2)
RewriteCond %{HTTP_HOST}<>%{REQUEST_URI} ^([^.]+)\.example\.com(:80)?<>/([^/]*) [NC]
# Rewrite only when subdomain not equal to first path element (prevents mod_rewrite recursion)
RewriteCond %1<>%3 !^(.*)<>\1$ [NC]
# Rewrite to /subdomain/path
RewriteRule ^(.*) /%1/$1 [L] 

[Persistent form data?]

Neither....

 

<?php

  echo'
  <form method="post action="'.$_SERVER['PHP_SELF'].'">
    <table>
       <tr><td><input type="text name="nombre" value="'.$_POST['nombre'].'"></td></tr>
       <tr><td><input type="submit name="submit value="doit!"></td></tr>
    </table>
  </form>';

?>

   

[[SOLVED] Stuggling Newbie]

If you don't have the server setup to parse PHP in HTML pages...then you need to rename the file extension to .php.

[echo-ing code]

If you want the HTML to be parsed as HTML...

 

<?php

echo '<a href="mypage.htm">My Page</a>';

?>

[echo-ing code]

If you want the html code to display as HTML....and not have it parse as HTML...

 

<?php

$string = '<a href="mypage.htm">My Page</a>";
$newstr = htmlentities($string);

echo $newstr;

?>

 

 

[echo-ing code]

Not sure what you're asking. Do you want to echo out actual code? Is that what you're asking?

 

[URL ReWrite - MonsterGamez.net]

Yes, I saw the subdomains. Reread my post. You can use something like the Apache mod_rewrite

[URL ReWrite - MonsterGamez.net]

Nevermind...re-read. Using subdomains.

 

You can use mod_rewrite if you're on an Apache server.

[[SOLVED] Can I open an image this way?]

Before trying to display your image, you need to debug your code/php to make sure you're pulling the value correctly from the database. You also need to make sure you're specifying the correct image path.

 

<?php

  $query = $db->query("SELECT * FROM usrinfo WHERE id = '$id'");
  $usrinfo = $db->fetch_array($query);

  echo'<img src="images/'.$usrinfo[uid].'jpg" alt="image info" />';

?>

 

[If you answer, you're PHP MASTER]

So its better to have few tables that have a lot of records, then a lot of tables and a few records?

 

Yes.

[If you answer, you're PHP MASTER]

Millions of Tables? Or millions of records? If we're talking tables...I would not recommend MySQL.

If the host/server configuration allows for run-time loading, you can upload the loader to an "ixed" folder.
