I'm used to seeing PHP code for uploading files which resembles:

Unfortunately, the condition $_FILES['userfile']['size'] is never satisfied.
Can anyone help me determine that my file is properly reaching the HTTP

Try var_dump()ing $_POST and $_FILES and see what you get.

If the problem statement isn't clear, all fault is mine :)


its not clear to me - but I'll take a guess and say that the relevant
content encoding headers were not set therefore php doesn't not recognise
the incoming post as a file upload.

// generating the relevant header via php
header('Content-Type: multipart/form-data')

// or specifying the enctype in a form tag declaraction:
<form action="" method="post" enctype="multipart/form-data">

it maybe that the header is not named 'Content-Type' - I was just guessing.

I have done very little SUM queries with time, can you
give me a quick example or any site where i can find a
few sample queries?

This is basic MySQL so you should RTFM, and generally should be asking
on a MySQL list :)

SELECT SUM( UNIX_TIMESTAMP( logout_time ) - UNIX_TIMESTAMP( login_time )
) AS seconds FROM some_table WHERE user_id = 1;

If you have MySQL >= 4.1.1 then you should probably use the TIMEDIFF()
function.

Cheers,
Rob.

Hehehe, true... 
Dont really like the MySql manual...its so much more
complicated compared to the php manual. And dont
really fancy joining a high traffic list like the
mysql one just for a simple q like the above when
there are so many experts here like you who take a
moment to help guys like me out. I usually dont ask
such basic q's anyway, although I admit the defination
of a "basic q" is very different to many ppl here...

Hi there,

I am somehow lost when it comes to regex. I am trying to remove ! and ?
characters from a string. Could somebody please help me to get a working
regex running for that?

I tried: $str = preg_replace('/\!\?\./', ' ', $str);



How about $str = preg_replace('/(\!|\?)+/', $str);
**NEVER** use regular expressions for simple search/replace operations!!! They are MUCH slower than a simple string replace, and should be avoided if at all possible. What you are doing is a very simple string replace, and you should not use regular expressions for that.
I am assuming you want to remove the ! and ? and not replace them with a space. In this case: 

$str = str_replace(array("!". "?"), "", $str);

Or if you did want to replace them with a space:


$str = str_replace(array("!". "?"), " ", $str);
This is especially important if you're doing the string replace in a loop, but even if you aren't, it is very bad style to use regular expressions for such a simple replacement.

I am using this pager class and I cannot seem to get the syntax right for 
adding the search string, area and service types to the url.

http://www.firepages.com.au/php_pagination_class.htm


Here is the full query...

SELECT * from contacts WHERE sname LIKE \'%%\' AND area LIKE \'%%\'AND 
p_service LIKE \'%%\' AND s_service LIKE \'%%\' AND t_service LIKE \'%%\' 
ORDER BY sname LIMIT 0 , 10


The search is a combination of surname, area and the three services it was 
suggested something like this would work

echo $pager->get_prev('<a href="{LINK_HREF}&area='$area '&sname='$sname" 
etc.

but I cannot get the syntax right and because the values are not 'resent' to 
browser the paged va;ue on pages 2, 3 4 etc are lost.

This has nothing to do with PHP, this is a javascript matter. You PHP script merely prints out the javascript code.

PHP is a server-side language. It cannot directly influence anything on the client-side. That is why you need to have your PHP script output a client-side scripting language such as JavaScript. You are still only executing PHP code on the server.

All that PHP can do is generate the text for the page that goes to the browser. It is the browser that does any displaying, and it is browser end tools you need to use to get a pop-up window.

With all due respect to my learned colleagues, my answer to your question is yes, you can accomplish your goal using just PHP.
I assume that you understand that PHP is not a client-side language and therefore cannot, by itself, produce a real-time, operating-system-generated pop-up dialog box in the same way that JavaScript can.
However, PHP can download a page with input fields disabled that includes a div styled to look like a dialog box with a couple of submit buttons labeled YES & NO. Submitting YES will request the same page from PHP but without the dialog div and with user interface fields enabled; NO will request the same page but without the dialog div and with UI fields disabled.
From the user's point of view, the main difference between doing this with PHP and doing it with JavaScript is that the PHP solution will take at least a few seconds for the round-trip to the server whereas JavaScript's response to a confirm() dialog will seem instantaneous.

Paul

I don't see a way to avoid the foreach loop, but...


            if(stristr($q,$injection))


rather than stristr() it's  faster (MARGINALLY!) to use stripos()
and test for a boolean false return value because your not interested in
the returned string (so why make php bother with grabbing and returning it)


            {
                //Do Something to remove injection and log it


if you get here I would suggest logging it and then stopping further processing
rather than trying to clean up the attempt to perform an sql injection.

Would it not a much safer and WAY faster method simply be to use mysql_escape_string()? What are you doing that allows users to give raw SQL to the server that you need to deny certain things? It seems like you're on very dangerous ground, letting users throw arbitrary SQL at your script.

I saw a post one day by Richard Lynch using the following interesting
approach:

<?php

    if( ereg( implode( '|', $dirtyWord ), $q ) )
    {
        //Do Something to remove injection and log it
    }

?>

This may ultimately be faster because it makes fewer function calls thus
bypassing function call overhead incurred for each word. And it's
probably even faster with PCRE.

Cheers,
Rob.

Hi all,

I wrote a php script that creates options for select boxes. What this
script does is selects tomorrows date.  However I have tested the code
when the day is the last day of the month and the script blows up.
Instead of displaying June it displays January and repeats the months
12 times I think.  I didn't count I just noiced thart that the months
of the year were repeated multiple times.

I think my problem is with the mktime function.  I don't think it
likes $i+1 too well.  I also want to be sure that this code takes care
of all date contitions like leap year, end of the year and any other
condition that would give a wrong date.

So here is my code:

<select name="month">
<?php
foreach(range(1,12) as $i)
{
        if (date('t') == date('j'))
        {
                echo "<option value=$i+1 selected=\"true\">" . date('F',
mktime(12,0,0,$i+1,1)) . "</option>\n";
        }
        if (date('n') == $i)
        {
                echo "<option value=$i selected=\"true\">" . date('F',
mktime(12,0,0,$i,1)) . "</option>\n";
        }
        else
        {
                echo "<option value=$i>" . date('F', mktime(12,0,0,$i,1)) . " 
</option>\n";
        }

Here is a one-line way to find the month and day of tomorrow:

<?php
list($tomorrow_month, $tomorrow_day) = split(':', date('m:d', time()+86400));

Hi,

I have been having problems that I am being classed as spam server if I use
the mail() function to send out mail to people who are using my system
(notifications etc). How can I avoid this? Anyone with experience?

Best regards,
Peter Lauri
