  • PHP mysql_fetch does not return values

    - by Petr
    Hi, Being quite new with PHP, I cannot find any solution why this does not work. The query is OK and the resource is returned. But I dunno why fetch_assoc does not print values. Thanks $query=sprintf("SELECT ID,NAME FROM USERS WHERE PASS='%s' AND NAME='%s'",mysql_real_escape_string($p),mysql_real_escape_string($n)); $result=mysql_query($query); if ($result) { while ($row = mysql_fetch_assoc($result)) { echo $row['ID']; echo $row['NAME']; } } }

  • Height of a webpage for snapshots in PHP

    - by gAMBOOKa
    We have an application that takes snapshots of certain web pages. It's quite tightly integrated into the code, so we're not ready to incorporate another library. But we don't have a way of being able to calculate the web page height, so we end up taking snaps of 8000px height. Which is now proving troublesome when inserted into PDFs. Is there a way to find the height of the webpage in PHP?

  • Tracking image views - PHP

    - by RS7
    I'd like for my app to be able to tell if an image hasn't been viewed in the last 30 days and remove it (along with data in the DB associated with it). I know you can have PHP read and output the image dynamically but I've heard its quite taxing on the system. Is there a way to for me to track these hits even when the image is viewed directly? (would htaccess be able to do this?) Thanks in advance.

  • PHP Redirect after execution of code

    - by UmYeah

If I do the following, will my email be sent reliably? Is a redirect what I really want to do? Random code to send email... header('Location: http://www.othersite.com/' + $_SERVER["REQUEST_URI"]);
