    RegExp for the 2nd question would look like this...

     

    #S[\d]{5}/[\d]{4}#

     

     

    Thanks for that and sorry for the old bump.

    If i would like to add a E to that, so both S18757/2002 and SE18757/2002 works, how would that look like?

    Well, i hope this is ending up in the right place, if not i'm sorry.

     

    First of, i'm still not that familiar with php as i hope to be.

    I have a a slight problem with a registration code that i need help with.

     

    First.

    if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", 
$email_address))
{
    $errors .= "\n Fel: Ogiltig E-mail adress";
}

if( empty($errors))

    This code works just fine. But i i want to remove the if( empty($errors)) line. How would the code look like then?

    I've tried several solution but non of them works.

     

    Second.

    I have to add a new code similar to the $email_address code named something like $med_nr, but the entering option would look something like this

    S18757/2002

    There's always a S in the beginning, 5 numbers then a / and then 4 numbers again.

     

    Any help with this is appreciated.

    Problems With Phpmyadmin And Importing

    in Applications

    Posted · Edited by jebediah

    Hi guys.

    Yes, the never ending story, and i cant solve it by my own.

    I want to import a database file on ~350mb. So i've change the necessary lines in the php.ini file.

     

    upload_max_filesize 400M

    post_max_size 400M

    max_execution_time 3000

    max_input_time 3000

     

    Well the upload seems to work fine now, but right after the upload to browser says "waiting for www.xxxxxxx.com" and after a couple minutes "6-7 min or so" i recive this message.

    Fatal error: Maximum execution time of 300 seconds exceeded in /dir/xxx/xxx/string_mb.lib.php on line 47

     

    Well, the line 47 in that file is

    return mb_substr($string, $start, $length);

     

    I'm out of ideas, and i don't think i have to mention that i'm new to phpmyadmin :)

    Ctrl+F5 hard refresh explanation and solution

    Sorry to bring up this old thread again, but i have same problem with another site.

    The site is only built with HTML.

     

    The problem.

    I have a div that i upload some picture to now and then and all new picture won't show up untill i press ctrl+f5.

    This only happens with Firefox and not IE. The thing is that i run my FF with default settings, so all other users with FF should have the same problem.

     

    What i've tried so far is

    <meta http-equiv="expires" content="wed, 09 aug 2000 08:21:57 gmt" />
<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="pragma" content="no-cache" />

     

    <img src="images/pic.jpg?34523576"/> [b]At all new picture[/b]

     

    And some that i found on the web

     

    <ifModule mod_headers.c>
# YEAR
<filesMatch "\.(ico|gif|jpg|jpeg|png|flv|pdf)$">
  Header set Cache-Control "max-age=29030400"
</filesMatch>
# WEEK
<filesMatch "\.(js|css|swf)$">
  Header set Cache-Control "max-age=604800"
</filesMatch>
# 45 MIN
<filesMatch "\.(html|htm|txt)$">
  Header set Cache-Control "max-age=2700"
</filesMatch>
</ifModule>

     

    # Turn on Expires and set default expires to 3 days
ExpiresActive On
ExpiresDefault A259200

# Set up caching on media files for 1 month
<filesMatch "\.(ico|gif|jpg|jpeg|png|flv|pdf|swf|mov|mp3|wmv|ppt)$">
  ExpiresDefault A2419200
  Header append Cache-Control "public"
</filesMatch>

# Set up 2 Hour caching on commonly updated files
<filesMatch "\.(xml|txt|html|js|css)$">
  ExpiresDefault A7200
  Header append Cache-Control "private, must-revalidate"
</filesMatch>

# Force no caching for dynamic files
<filesMatch "\.(php|cgi|pl|htm)$">
  ExpiresDefault A0
  Header set Cache-Control "no-store, no-cache, must-revalidate, max-age=0"
  Header set Pragma "no-cache"
</filesMatch>

     

    No one works. So is there any other solution?

     

    EDIT: Just notices that this question should be posted at HTML section? Mod, or should i start a new thread?

    Sweet, i really appreciate that you took the time to explain. Not often a newcomer get that kind of help :)

     

    For static files the web server (like Apache or IIS) should handle caching automatically.

     

    Any idea what the "default" time for this is, if any?

    Most of my problems is that images are not updated as soon as i've uploaded them.

    Lets say that i do some minor changes on a picture in the header, the new one wont appear untill i make a hard refresh.

    What i've noticed though is that if i wait like 24 hours or so "without a hard refresh", the new picture will appear automatically. So it has to be some kind of timespan somewhere?

     

     

    In my experience caching problems are almost always the result of the web server not handling caching for static files, like scripts and stylesheets, as you expect. Like they'll send Expires headers* that last a long time, or generate ETags** using limited information. Both of those can be fixed quite easily but you only need to do so if you discover a problem.

     

    It is not every day i change the .css file, but it happens some times :)

    When that day comes, is the code that i posted earlier a good choice then?

    Hi guys. First of, English is not my spoken language so have patience :)

     

    I've google it and done some reading regarding "hard refresh" but i cant find the information i'm looking for.

    Lets say that i visit a website that i've visit 6 month earlier, and what if they done some changes that require a so called hard refresh. How should people know that the site require a ctrl+5?

    I mean, i could be visit sites that looks different without my knowledge, that could been changed several month ago?

     

    How does it work? Is it manage automatically or is it up to the webmaster to implate some codes like

    <?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>

     

    I dont know much about site development and i try to learn as much as i can. Is there no better way to handle this.

     

    And my second question.

    Where should i paste codes like this to solve the cache problem? In the header.php?
