[PHP] Stopping bad entries in PHP form
I have a PHP form that allows end users to request a sample of the products we sell. Unfortunately, a person/people have found it and are sending in bad requests. We sell only within the US, and so I've set up the form so that they must choose one of the 50 States. But we keep getting requests with countries in the city field, i.e. "Moscow Russia". Is there a way that I can scan for country names, etc. in the text fields and stop a request from going through if it finds one of those "banned" words? I've searched for a solution but haven't been able to find it. If this is not enough info, please let me know. Also, I only know enough PHP just to be dangerous, so please be kind. =;) Thanks, Frank -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Possible Server Infection?
Hi all, I was wondering if someone might know about a problem I'm having on my server. It appears that I've been infected by a rogue PHP script(?). Something has gone through my server and placed .htaccess files in every directory that didn't have one with contents that look like this: Options -MultiViews ErrorDocument 404 //graphics/cc/52.php The path is different for each file and corresponds to the directory that it's in. The php document name is a different number for each file I've found. Does this sound familiar to anyone? What would be the purpose of placing files like these in the directories? As far as I know, there isn't a file called "52.php" anywhere on my site, so this doesn't make any sense to me. I realize that this is a very general question, but I'm hoping that someone has seen or heard of this type of thing before and can help me eliminate the problem. I'm using A2 Hosting and they don't know why this happened. Thanks, Frank -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Multiple MySQL Queries
This may be more of a MySQL question than PHP, but I'm hoping someone
can point me in the right direction. I have working code (below) that
pulls data from a particular category in our db. I'd like to be able
to pull data from multiple categories in the same db and place them on
the same page.
I've been working on this for the last 4 days with no luck. Some
pages say that you can't do multiple MySQL queries while others say
there is a workaround but I haven't found it. Does anyone know how to
do this?
Thanks,
Frank
// in header

catalog WHERE categories='" . $cat1 . "' ORDER BY itemid",$db);

18367C4 $97.37 A18367C4 --- $82.55
I got the headers to work with this code:
...
foreach ( $cats AS $cat ) {
echo 'Item ID';
echo 'Description';
echo '(Click for more info)';
echo 'Price Each';

(I don't need to show the category #'s in the header fields) but I

[PHP] Better Formatting Options?
Is there a more efficient way to write the following?
itemid='ABC1'",$db);
printf("List: %s\n", money_format('$%i',
mysql_result($result,0,"priceList"))); ?>
I have many products per page and this code pulls the list price and
formats it. It works fine, but I'd like to know if I can shorten it.
I've looked at number_format over money_format and it's a little
shorter, but not by much. Are there better options than printf and
mysql_result for my use?

Re: [PHP] Multiple MySQL Queries
I've run up against something else here that I can't find an answer
for. This line of the script:
$cats = array('01100-01200-01300-06403' => 'Starter Units',
'01100-02201-01300-06403' => 'Add-On Units', '01100-99222-11341-18451'
=> 'Extra Shelves');
is supposed to pull all items from each category and gives each table
a heading. Unfortunately, if a product in the db has more than one
category assigned to it, it will not show up in the generated table.
So, if an Extra Shelf has a second category, the categories are stored
as 01100-99222-11341-18451``07108-05253-12341-01451 and if it has 3
categories assigned to it, they're stored like
01100
-99222-11341-18451``07108-05253-12341-01451``07108-01254-39341-01451,
and so on.
Is there a way that I can tell the array to find all products whose
categories either equal exactly the category I'm giving it or if it
_contains_ that particular category? I've tried using the * wildcard
but that didn't work. I've also tried WHERE categories CONTAINS
'$cat' but that didn't work either.
Any insight into this would be greatly appreciated. If I can't find
a fix for this problem, this whole script is useless to me, as most of
our products have multiple categories and so it will only display a
portion of the products that it should, if any at all.

[PHP] Displaying 2 digit minutes/seconds
Hi all,
I'm using this code to display the current time for our location on
our website:
$theMinute = $theTimeIs['minutes']; // make minutes
under 10 show two digits
$theSecond = $theTimeIs['seconds'];
if($theHour > 12){
$theHour = $theHour - 12;
$dn = "PM";
} else {
$dn = "AM";
}
echo "$theHour:$theMinute:$theSecond $dn";
?>
It works great except for one small detail. If the time is 3:04:02,
it is displayed as 3:4:2 which, of course, is very odd looking. So I
corrected it as follows:
12){
$theHour = $theHour - 12;
$dn = "PM";
} else {
$dn = "AM";
}
echo "$theHour:$theMinute:$theSecond $dn";
?>
It works, but is there a better way to do it?

[PHP] PHP Shopping Cart Recommendation
I'd like to get everyone's opinion on a good PHP shopping cart. We need something that will handle a lot of similar items and can be geared for an industrial site selling products from different manufacturers. It needs to be PCI compliant and able to handle at least 5 sub-category levels. I'd also prefer to have it _not_ display the items until after you've drilled down to the final sub- category. The cart needs to be rock solid and should look professional. We're not looking for wizz-bang, look-at-me fancy. We're selling commercial items here, not women's shoes.

I have an itemID field that contains item #'s that include dashes, forward slashes, etc, and I want people to be able to search for an item # even if they don't enter the punctuation exactly. Here's an example: let's say there is an itemID of 4D-2448-7PS but someone omits the dashes and searches on 4D24487PS. Is it possible in PHP to have the find be successful, even if the search criteria doesn't exactly match what's stored in the field? If this is possible, I'd appreciate it if someone could just point me in the right direction so I can read up on it.

Re: [PHP] Searching on AlphaNumeric Content Only
Thanks to everyone who has responded. After reading everyone's response, I think I have a very simple way to solve my "problem". Using my original example, if someone wants to find item # 4D-2448-7PS, no matter what they type in, I'll take the input, strip out all non-alphanumeric characters to make it 4D24487PS, add the wildcard character between each of the remaining characters like so, 4*D*2*4*4*8*7*P*S, and then do the search. Still being new at this, it seems to be the simplest approach, or is my thinking flawed? This also keeps me from having to add another field in the db to search on. BTW, this solution needs to work with any db, even ASCII files, so it has to happen in PHP.

[PHP] Include Files in HTML
In my readings, I've run across examples showing include files being called from within the tags, and other examples showing them called within . I've always put them in the header section myself, but I was wondering if one is better than the other, or is it just personal preference?

[PHP] RIGHT Function?
Hi all,
I could use some help. I've scoured both the MySQL and PHP sites
that I know of and can't find an answer to this.
I have a price field that sometimes contains entries like this:
250,(min)
5.32
How can I pull just the price ($5.32 in this example) from this field
to display on a web page? Is there a RIGHT function in PHP? When I
search the PHP site, I'm being told there isn't one.
Here's the code I've been using:
WHERE itemid='WR-1240'",$db);
printf('List: $%s', number_format(mysql_result($result,
0,"priceList"),2));
printf('Your Price: $%s', number_format(mysql_result($result,
0,"unitprice"),2)); ?>
Thanks,
Frank

Re: [PHP] RIGHT Function?
I think I've solved a problem that I had posted back in September. Here's a recap: == I need to grab a dollar amount from a text field in a MySQL db that can contain more information than just the price. Here are 4 examples of what could be in that field: 48,(min) 2.66 24,(min) 10.50 4,(min) 104.82 98.56 If there is more info in that field than just the price (as in the first 3 examples), the price is always on the 2nd line. == The following code works with the tests I've given it so far, but I just want to double check before I go live with it: ... if ($position = strpos($item['unitprice'], ')') ) $price = "$" . number_format(substr($item['unitprice'], $position + 1),2); else $price = "$" . number_format($item['unitprice'],2); ... Legend: $item['unitprice'] is coming from a MySQL statement I'm grabbing the position of the right parentheses and adding 1 to it. Then the substr grabs everything from that point to the end of the string, correct? If there isn't a ")" in the field, then the else statement should be performed. Can anyone see any errors in my code? Would there be a better way to write this?

Re: [PHP] RIGHT Function?
Hi Jim, $parts = explode(PHP_EOL, $item['unitprice']); $price = '$'.(( count($parts) > 1 ) ? $parts[0] : $parts[(count($parts)-1)]); Thanks for the code! After reading up on PHP_EOL and explode, I now understand what you've done. However, can you tell me why you like this better? Is it because it is cleaner without the if/else statements, or is there more to it than that?

Re: [PHP] RIGHT Function?
Jim,
$parts = explode(PHP_EOL, $item['unitprice']);
$price = '$'.(( count($parts) > 1 ) ? $parts[0] :
$parts[(count($parts)-1)]);
For some reason, I couldn't get explode to work with PHP_EOL.
$parts[0] would return the entire field, so apparently it wasn't
"exploding". So I tried exploding on the ')' instead, which worked,
but the return character that's after the ')' was included in the
output, i.e.:
$
6.56
so I added 'trim' which took care of that. I also had to use
'number_format' again, since there are exact dollar amounts like 413.
Here's what ended up working for me:
$parts = explode(')', $item['unitprice']);
$price = '$'.number_format(trim((( count($parts) > 1 ) ?
$parts[(count($parts)-1)] : $parts[0])),2);
Any idea why PHP_EOL didn't work? If I could get it to work, I could
remove the trim function and 2 of those parentheses, which would look
a lot nicer.
Thanks again,
Frank

You basic problem with the PHP_EOL is that when echo'ed out, it
represents a \n character.
The value you are working with might be \n\r or just \r
I read the links you sent, plus some others. It took me awhile, but
I get it now. If the "return character" that was entered into that
field is not the same as what PHP_EOL is looking for, it won't work.
$parts = preg_split('|[\n\r]+|', $item['unitprice']);
preg_split works perfectly! Very similar to Perl's split function.
Here's what I have now:
$parts = preg_split('|\s+|', $item['unitprice']);
$price = '$'.number_format((count($parts) > 1) ?
$parts[(count($parts)-1)] : $parts[0],2);
Clean and concise. Thanks a million, Jim! I really appreciate your
helpful responses.
Thanks again,

[PHP] Blocking URL hacking attemps
I'm using a script called BlackHole that uses PHP and a "hidden" directory to catch bad bots and block them by their IP address from the site [http://perishablepress.com/blackhole-bad-bots/]. It's working very well, but I'd like to expand on the idea. When looking at our access logs, I see someone "adding code" to our URL's in hopes to, apparently, hack into our site. If our URL is like this: http://www.example.com/pages/bolts.php they are adding to it like this: http://www.example.com/pages/bolts.php/wp-content/themes/functions/thumb.php.cache/external_e19f4bb51bc2262e07d23b79b916c12c.php or http://www.example.com/pages/bolts.php/cart.php or http://www.example.com/pages/bolts.php/wp-content/themes/functions/thumb.phptimthumb.php or http://www.example.com/pages/bolts.php/bratislava/stare-mesto Is there a way that I can trap the "extra" info in the URL's and pass it to the BlackHole script to ban these attempts as well? I'm thinking I'll need to compare the entered URL with $_SERVER["PHP_SELF"] and if there's extra info, like another "*.php", after the page name, then ban the IP. I realize that's a rather simplistic explanation and there may be a better way to accomplish this. If anyone has any examples they can share, I'd really appreciate.

[PHP] Array Symbol Suggestion
I'd like to make a suggestion for a change, or possibly an addition, to the PHP language. I'm learning PHP and have been very excited with what it can do in relation to HTML. But when I got to the part about arrays, I was disappointed to see that they are designated with a $ the same as other variables. I was learning Perl before I switched, and it uses the @ sign to designate an array. That makes it a lot simpler to see at a glance what is an array and what isn't - at least for beginners like me. Has there been any talk of adopting the @ sign for arrays in PHP? Or is that symbol used for something else that I haven't read about yet? What is the proper channel for making suggestions like this?

Re: [PHP] Array Symbol Suggestion
Thanks for all the responses to my suggestion. I realize this would be a major change, so that's why I also mentioned it as an addition to the language. I'm sure it's just what you're used to, but still being new to all this, it just makes sense (to me anyway) to have different symbols for different variable types: $scalar @array #hash Since the @ sign is already reserved, maybe there's another symbol that would work better? I don't know. These are just ideas that I came up with while reading and I thought I'd throw it out there to see what others thought. I like the idea of a naming convention, so that's what I'll do in my scripts. I also appreciate the heads up on is_string(), is_array(), and var_dump().

Sometimes when you ask a stupid question you end up getting a brilliant answer. I had no idea about any of this until I received your response, which got me digging. I found out that I could create a custom php.ini file for my site, and within hours of doing this, I had errors logged that I didn't even know I had and was able to fix them. I've since created a cron triggered script which e-mails me any errors on my site. So thanks, Stuart, for posting your response. So far it's caught a coding mistake (by me) and a "no product found in MySQL" error (because of a discontinued item). I don't mean to sound dramatic, but this changes everything for me. It's great to know that I'll be notified of any little (or big!) problem without having to manually hunt it down.
