[PHP] Re: Using Logical OR operator in IF statement???
Hi Brad,
This worked for me:
?
if ((substr($sString, 0, (strlen($sString)-1) == -)) || (substr($sString,
0, 1) == -)) {
echo you can't have a dash at the beginning or end of your string.;
}
?
.. but I'd tend to go for a regex as a solution to what you're after,
which involves less code:
?
if (preg_match(/^-|-$/s, $string)) {
echo You cannot have a \-\ character at the beginning or end of your
string.;
} else {
echo Whatever;
}
?
Just my thoughts...

Hello,
Ok, this works:
if (substr($sString,(strlen($sString)-1)!=-)) {
print You can't have a dash at the end of your string.;
}
and this works:
if (substr($sString,0,1)!=-) {
print You can't have a dash at the beginning of your string.;
}
But, this doesn't work for any case:
if ((substr($sString,(strlen($sString)-1)!=-)) or
(substr($sString,0,1)!=-)) {
print you can't have a dash at the beginning or end of your string.;
}
What could be wrong? I've used a logical OR operator in the middle of an
IF
statement like this before, but for some reason, this just isn't working.
Anyone got any ideas? I suppose I can just evaluate this with two
different
IF statements, but it seems like I shoud be able to do it in one and
reduce
duplicate code. Thanks very much in advance.

[PHP] Re: parsing a string

something like this might work:

John A. Grant [EMAIL PROTECTED] wrote in message
[EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
I'm reading some HTML text from a file and echoing it to
stdout. The HTML text contains IMG but I would rather
have the server do the work of looking up the image size.
I know how to lookup the image size with getimagesize().
My problem is in coming up with a good format for embedding
a reference to the image in the text and then writing the code
to parse it.
So instead of this:
here is some text img src=bird.gif width=100 height=20
alt=this is a bird and here is more text and another
image img src=plane.gif width=123 height=23
alt=this is a plane and more text
I would like to have something like this:
here is some text [bird.gif,this is a bird] and here
is more text and another image [plane.gif, this is a plane]
and more text
Crossing line boundaries is not an issue - each text string
is complete. I need to be able to dump out the string until I
see a reference to an image, then extract the name and alt text,
handle it (by emitting IMG) and continue to echo text from
the string until I encounter another image reference.
My problem is in coming up with a syntax for this and then
to write the code to extract the information.
In the above example, I'm using the syntax:
[filename,text]
but it's conceivable that the HTML text might also contain
[some plain text not related to images]
so I thought about some of these:
{filename,alt text} - not good, text might contain {plain text]
@filename, alt text@
img(filename,alt text)
Using the same @ delimiter at each end might make it easier
to use explode() to split the text. But perhaps img(filename,text)
is more elegant, but it might need more skills than I have in using
regex to recognize it and extract it. Also I need to figure out how
to extract and echo the plain text around it.
Any ideas are appreciated. Thanks.

Re: [PHP] local time v.s. server time
Hi Joe,
GMT isn't affected by daylight savings (altough in the UK we are using
British Summer Time at the moment, which is GMT +1), so that's the constant
you can work from if you're not experiencing daylight savings schemes where
you are. I have written out an example for you below.
We get the Y-m-d H:i:s format of time using gmdate() (which Mysql likes).
We convert that lot to a timestamp. The function I've created takes two
arguments: whether to add or take time from the timestamp that is generated,
and the offset in hours. So, to emulate what Mysql's now() function does,
you can do something like this
?
$now = GenerateOffset(-, 6); // takes off 6 hours.
$query = @mysql_query(INSERT INTO table (datetime) VALUES ('$now'),
$connection);
?
And you should get correct datetime formats for your timezone into your
table (providing you have put your correct offset from GMT).
?
function GenerateOffset($plusminus, $offset) {
$datetime = gmdate(Y-m-d H:i:s);
list($date, $time) = explode( , $datetime);
list($year, $month, $day) = explode(-, $date);
list($hour, $minute, $second) = explode(:, $time);
$timestamp = mktime($hour, $minute, $second, $month, $year, $day);
if ($plusminus == +) {
$newtime = $timestamp + (3600 * $offset);
} else {
$newtime = $timestamp - (3600 * $offset);
}
$newdate = date(Y-m-d H:i:s, $newtime);
return $newdate;
}
?
Hope this helps.

convince them to set the timezone to my location, thus throwing everyone
else on the same server out of whack...
I can use the putenv() function though for use in PHP and then when saving
the date and time into mySQL actually use the PHP date and time functions

Where would I find the TZ codes to use for my area?

[PHP] Help with linux / apache / php
Hi all, I'll apologise right away - this is more or less completely off topic, though it is remotely connected with PHP (so that's my excuse). At the moment, the company I work for is hosted on a co-located server. We have one main domain and many sub domains. Here's how they are (roughly set up): www.mainsite.com www.sub1.mainsite.com www.sub2.mainsite.com www.sub3.mainsite.com www.subn.mainsite.com The document trees are like this: /home/mainsite/www // main dir /home/mainsite/www/sub1 //sub 1 /home/mainsite/www/sub2 // sub2 (etc) We have just (in the last month or so) leased a cobalt raq all for our own use. Great. However, the sites using this box are setup and maintained using a web interface that comes as default with the box. when setting up sites (subs or otherwise), it adds sites (and you have to specify users for those sites) with directory trees like this: /home/sites/site1/web /home/sites/site2/web (etc) Obviously, this causes problems (like for the php scripts that are running on the current setup, where files are included / required as a part of the main directory, and out of the document root (/home/mainsite/includes might be an example)). So, I'd like to learn how to use linux (bearing in mind that I have very limited experience of unix based systems). I can perform the very basic commands, but would like to learn how to use / mainpulate the box through shell access rather than over a web interface (which ultimately, I'm assuming, will give me more flexibility - for example, I'd rather know how to install the latest version of php onto the server following the installation instructions than to attempt to do it through another medium). I've bought a couple of books and hope to delve into them in the course of the weekend and the next few weeks to come. I'm assuming that one of the first steps would be to install linux on my home machine and get a feel for it (currently I'm running windows ouch). So, here come the questions. Where can I find the latest version of linux? I have had a brief look at freshmeat.net and linux.com, but didn't find any download sections (I didn't look too hard, for reasons soon to be explained). If I install linux, can I still use windows as a secondary OS (perhaps running over the top of linux?) If I can run windows as well as linux, am I best formatting my main drive, installing linux, then windows? Is the httpdconf file one of the main files i need to confifure for sites, or are there many others (I've read a little about setting users up in vi and will read more on that, but are there mounds of files that you need to configure when setting up a new virtual site?) I'm sorry about asking what's probably obvious to most of you, but that's part of my reasoning behind asking on here - most of you will probably be familiar with this stuff. Another reason for asking here is that I don't know of any other relevant alt groups. I'm sure these questions have been asked many times before, but it really has been one of those weeks, and I'm about fit to drop dead of exhaustion (not your problem, I know, but the sympathy vote might work ;)) - I've had a quick look through the archives and other sources, but the mounds of text that surround the basic questions I'm asking are (in my dazed state) making me even more dizzy. Lastly, thanks for reading. Any advice any of you can give, or any basic pointers you might have, are greatly appreciated. Please cc any replies.

Or

This matches p (or P), followed by any character string that
DOESN'T include a , then the trailing .
Preg functions are faster, though. And, if you're interested in
little speed tweaks, use single quotes - ' - rather than double
quotes - - here. With double quotes, PHP searches the quoted string
for variables or escape characters to replace.

[PHP] Re: Types of table....
Hello Steve,
well, you should have the table set, at the very least, something like this:
UserId - INT, Primary Key, Auto increment
RealFName - varchar(20)
RealLName
UserName - Varchar (20)
PassWord - Varchar (12)
The length of the fields is optional, and you should perform checks on the
username and password to confirm that they don't contain irregular
characters that might give you problems in the future.
I'd do something like this (on signup):
if (!preg_match(/^[[:alnum:]_]+$/, $username)) {
//error
}
-That'd check if the username contained alphanumeric characters and the
underscore (_) character. I'd take out the underscore for the password.
Having the first and last name in separate columns will allow you to perform
more informal greets to the user when you use this - Hello $RealFName, how
are you?
Look up column types in the MySQL manual at mysql.com for more detailed info
;)

How are you executing the script? Does it come by and run 'php

it? I've found that works well... just put that as the first line, and
it behaves as a shell script (after you make it executable, of course)

Do I have to write the php scripts differently to how I would if they

Re: [PHP] include and include-virtual
Christian, Those are SSI calls (Server Side Includes, for use with .shtml files). Try: include(/path/to/filename); require(/path/to/filename); I've never used these, but in PHP4 there are also: include_once(/path/to/filename); and require_once(/path/to/filename); (double check that I have gotten those function names right). If you REALLY need to use something like exec cgi, I guess you could create an shtml file with the command in, then include() or require() the shtml file. James.

Re: [PHP] Uploading files
Hello Diego,
You need to use copy()
If the form input is like this: file: input name=userfile type=file
input type=submit
Then PHP will assign a few variables automatically to the file, which
include:
$file_name - actual name of the file (pic.jpg)
$file_size - size in bytes of the file
$file_type - MIME type of the file.
This:
input type=hidden name=MAX_FILE_SIZE value=1000Send this
Will only let you upload a file of less than 1kb if you program around that
(1024 bytes in a Kb). Setting to 102400 would give you a max upload size of
100 Kb.
So, simply:
?
if ($file_size $MAX_FILE_SIZE) {
@copy($file, /path/to/dir/ . $file_name)
or die (Something's up.);
} else {
echo Sorry. Your file was bigger than the allowed size of .
round(($MAX_FILE_SIZE / 1024), 2) .Kb. Please go back and try again.;
}
?
You can of course test whether the file being uploaded is a type you want,
like image/jpeg from the $file_type.
Hope this helps.
James.

Re: [PHP] coding for 'no match found'

Subject: [PHP] coding for 'no match found'
This is a simple yet fundamental programming question I am
hoping somebody will
have the patience to explain...
I have a mysql database with the email field as the key.
Before inserting an
new record to it I want to check if there is already a record
with that e-mail.
This I can do fine. But this script needs to also handle
delete requests,
which I can also do fine, but I need to code for the instance
that there is a
delete request for an e-mail record that does not exist. How
can I figure out
if after my 'while' loop is finished checking the database it
has not found a
match (so i can inform the requester as such)?
Here's the code I have so far...
$email_check_query = SELECT email FROM
$tablename WHERE email = '$email';
$email_check_result = mysql_query($email_check_query);
while($email_query_data =
mysql_fetch_array($email_check_result)) {
$db_email = $email_query_data[email];
//if match, it's an update or delete
if ($email==$db_email) {
if ($op==delete) {
$action=del;
echo delete
requestbr;
}
else {
$action = upd;
echo update
requestbr;
}
}
} //end while loop

Re: [PHP] mysql_trouble (check fast!)
Hi Fredrik,
Always check whether or not the required variables are there BEFORE querying
the database. And make sure that the negatives are dealt with first.
That's my opinion. I'd probably also check whether the original username /
password is in the database before proceeding. Probably more work on the
db's part than needed, but still. Gotta make sure everything's correct:
?
if (!is_set($new_password)) {
echo You haven't assigned a new password. Please go back.;
} else {
$sql_check = SELECT id FROM users WHERE username = '$username' AND
password = '$password';
$result_check = @mysql_query($sql_check, $connection)
or die (some graceful error);
if (mysql_num_rows($result_check) == 0) {
echo The username and original password you entered did not match
anything in the database. Please go back and try again.;
} else {
$sql_update = UPDATE users SET
password = '$new_password'
WHERE username = '$username';
$result_update = @mysql_query($sql_update, $connection)
or die(Another graceful error.);
echo Your new password has been saved.;
}
}
?

[PHP] MySQL select rand() with weighting?
Hi Guys, Does anyone know how to select one field randomnly from a MySQL table against a weighting column in the same row the field is selected from? For example, SELECT id, url, image FROM table ORDER BY rand() LIMIT 1. And have a column like weighting where values between 1 and 100 are held - The larger values making it more likely that they're going to get pulled out. So say I have three rows in the table, one weighing 100, the others weighing 50, the one weighhing 100 stands a better chance of being selected randomnly? I know I've not explained this too well, but hopefully *someone* will know what I'm rambling on about ;) Thanks as always, James. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] String delimeters, arg!
Hi Nick,
to delete a cookie, simply use set_cookie(cookie_name); without appending
any values.
Possible solutions for the \t and \n :
For \n to br, use:
$string = nl2br($string);
Not sure whether or not there a similar function for \t, though you could
perhaps use some method to replace \t with nbsp; * 4. I'm not sure
something like:
$string = ereg_replace(\t, nbsp;nbsp;nbsp;nbsp;, $string);
would be too clever, just in case someone typed \t rather than ereg_replace
/ preg_replace recognising it as a Tab.
It's getting too late to do any serious thinking. :)

Hello PHP'ers
I am having a problem with string delimiters. For some reason no matter what
I do I can not get them to process correctly!!
For example,
?
$area_entered = yes;
$date_entered = no;
echo $area_entered\t\t\t$date_enteredbr;
?
That outputs:
yes no
What am I doing wrong?! Is there something I need to set in the php.ini
file? I would like to be able to type \n instead of br repeatidly!
Also, when working with cookies, if I have a cookie that is set by,
if (!isset($cookies)) {
//Set Cookies
$cookie_user = setcookie (username, $row[user], time()+86400, /,
localhost);
$cookie_pass = setcookie (password, $row[pass], time()+86400, /,
localhost);
$cookie_step = setcookie (step, 1, time()+86400, /, localhost);
$cookies_set = setcookie (cookies, y, time()+86400, /, localhost);
}
Is there a way to unset the cookie? Perhaps by,
$cookie_set = setcookie (cookies,);
?
Thanks for your time,

Re: [PHP] simple querying mysql in a WML card problem :(
Hi Sandeep,
The br tag looks like this in wml: br/
Have you escaped the doublequotes correctly in your double quoted echo 's?
Make sure that the database doesn't contain ampersands, or dollar signs, or
some of the foreign lettering (like é), as they are illegal characters in
wml (well, the dollar sign is used for variables, like PHP, but WML can't
accept them as part of a string as PHP does).
Ways to work around:
$string = ereg_replace(, , $string);
or
$string = ereg_replace(, amp;, $string);
To get a dollar, use two dollars:
$string = ereg_replace($, $$, $string);
That's about as much I can suggest, without actually playing with the script
myself And I am too tired for that. :)

Re: [PHP] Incrementing dates
Hiya Martin.
You'd probably be better working around a database solution to your needs,
but I am a bit drunk (and probably can't sensibly attempt to answer your
question properly), but it got me thinking, so I decided to have a play with
date incrementations. If anyone has any comments on this, I'd like to hear
them (there's probably a simpler way around what I have done). Here's the
URL:
http://www.yorkshire-zone.co.uk/date_increment.php
And here's the code that powers it:
HTML
BODY
?
$date = date(2001-04-28);
list($year, $month, $day) = explode(-, $date);
$actual_date = mktime(0,0,0,$month,$day,$year);
$days_to_add = 7;
$x = 1;
while($x = $days_to_add) {
$make_date = getdate($actual_date);
echo Day $x: $make_date[mday] $make_date[month],
$make_date[year]BRBR;
$actual_date = $actual_date + (3600 * 24);
$x++;
}

[PHP] SQL Select Unique() ?
Hi Guys, Is there a method of extracting rows from a MySQL table Uniquely (as in only once) ?. For example, when a user performs a search, using two words, it may return the same row twice if the search is spread over two or more SQL "selections". An example: If hypothetical row 129 is a Public House, but the public house doubles up as a restaurant, a search like this might return the same result twice. Here is our hypothetical pub: id = 129 name = The Blue Bell Inn category = Public House description = The Blue Bell Inn is a hypothetical pub, in the heart of rural England. Why not visit, have a drink and perhaps even dine in our fine Restaurant area. The user might perform the search, searching by "category" OR by "description". So if they typed "Public House / Restaurant" as the query, the following would occur: $sql = "SELECT * FROM table WHERE category LIKE 'Public House / Restaurant' OR description LIKE 'Public House / Restaurant'"; Surely that would bring the same row back twice. Is there any way of selecting from the table just once, without having to restrict the search facility to something like: "SELECT * FROM table WHERE category LIKE '%$searchtext%'"; as opposed to having the "OR" in as well?

[PHP] Problems with string replacement
Hello all,
Well, I'm having problems again. This time with string replacement. I'd
like people to be able to write notes on one of the site's I'm helping with,
and would like them to be able to use Bold, Italic, Underline and a href
tags. I tried using striptags(); but that would strip anything within
double quotes too. So I've gotten around it by converting the message
string to htmlspecialchars and then using ereg_replace around the tags I'd
like to allow, ie:
$message = ereg_replace("lt;ugt;","u", $message);
Where I'm struggling is with the a href tags, though. I've been using this:
$message = eregi_replace("(lt;a
href=quot;)(http://[^[:space:]]{1,})(quot;gt;)(.*)(lt;\/agt;)", "a
href=\"\\2\" target=\"_blank\"\\4/a", $message);
which would change a string containing:
a href="http://www.php.net"PHP!/a
to:
a href="http://www.php.net" target="_blank"PHP!/a
Great. But, there's a problem. If someone uses:
a href="http://www.php.net" target="_blank"PHP!/aa
href="http://www.php.net" target="_blank"PHP Again!/a
it returns:
a href="http://www.php.net" target="_blank"PHP!/agt;lt;a
href=quot;http://www.php.netquot;PHP AGAIN!/a
Ouch!
Anyone got any ideas where it's going wrong?
Also, for the html that isn't allowed, it'd be nice to have some sort of
cleanup, so that something like this:
blahBLAH/blah
Would be returned as BLAH. But not essential :)
Thanks in advance,
James.

True, but then it doesn't:
-Open the link in a new window
it does:
-remove all content between "and".
Of course, I could replace quote marks with htmlspecialchars/entities or
using manual string replacement, but then it'd render all tags using quote
marks invalid.
See the problem? ;)

[PHP] Maximum queries from a database?
Hi all, I'm a little concerned as to how many times some of the scripts I've been working on are querying a database: Some are making up to 4 or 5 queries each. Should this give me any cause for concern? I've only ever been unable to connect to the database once (other than through script error), and that's when I was using a persistent connection. So, I guess my question is, is there a recommended maximum number of queries I should be working around? (MySQL).

Re: [PHP] How to delete session variables
I thought that session variables (unless set to cookie as well) WERE destroyed at the end of a session? As in when the user closes the browser? Hrms. Maybe not. Anyway, don't know about when the window is closed, but you could have a log-out page that uses session_destroy(); James. I would like the session variable to be deleted when the user closes their browser. Any ideas on how this is done.

[PHP] Simple REGEX?
Hi guys, I'd like to restrict the characters a client is inputting to a database. I already have a system that'll exclude certain characters.

[PHP] Finding the? in $REQUEST_URI?page=blah
I really wouldn't ask this if I wasn't completely exausted, but the last
thing I feel like doing just now is reading up on this when someone can
probably answer it in a matter of seconds.
OK, I've an error handling page. Basically, I want to split (that might
even be one of the functions I'll have to use) this sort of url:
error.php?/pages/login.php?username=name
into:
/pages/login.php
I'm using :
header("location: error.php?page=$REQUEST_URI");
When echoing the request_uri back on the error page, it omits the error.php?
bit, so I get:
login.php?username=name
The reason I want to do this is so that I can use a re-login form that will
submit to the page the user has badly logged into, so if they logged in to
main.php, the request_uri would be something like:
/pages/main.php?username=name
Which I'd want to rebuild on the error page, into a form, like:
form method="post" action=? echo "$REQUEST_URI"; /* Minus the suffix the
page may include */ ?"
Username: input type="text" name="username"r
etc/form
Can anyone help?
Thankees :)

Re: [PHP] splitting up contents of a test box
If each of the scrolling lines is separated by something regular, like a carriage return, or a line break, tab (etc), you could use explode(); and have the values returned as an array. James.

[PHP] returning multiple variables from a function?
Hrms. Got a small problem.
I'm now using functions on a regular basis, but I've come to another
sticking point with them: returning multiple variables from the function...
Here's a really quick example (nothing to do with what I intend to use the
functions for):
function CUP ($connection,$username,$password) {
if (($username) ($password)) {
$sql = "SELECT username, password FROM table
WHERE username = '$username' AND password = '$password'";
$result = etc etc
$num = mysql_numrows($result);
if ($num != 0) {
$valid = "yes";
}
return $valid;
}
$correct_user = CUP ($connection,$username,$password);
Now, if the user is correct, I'd get a return of
$correct_user = "yes";
What if I wanted to "return" more than one variable from the function? And
how would I assign it a name? Like the actual variable, or is that just not
possible?
I've tried
return $var1,$var2;
But got an error.
As always, tia :)

Re: [PHP] Getting MIME-type of file
Oops, I forgot to mention the most important part...
I need to get the MIME-type (or something that can identify the
file-extension) from a file ALREADY on the server, not posted through a
form.
I.e. How do I get the MIME-type of "tobias.zip" in my folder?
I already know how to get the MIME-type from a form...
Thanks for the nice snippets though. They might come in handy in the
future.
Just knocked this together. It doesn't confirm whether or not the files are
actually valid MIME types (like .zip). For instance, you could upload a
text files, rename it to .zip and it will list it (if you change the
following $required_types variable I've put in here:
__
html
head
titleLooking MIME types?/title
/head
body
Here is a listing of the directory I want to be looking in and all of the
files in it. If the files are listed below, they're the ones I want to
know.
ul
?
$directory = "/path/to/directory/";
$dir = opendir($directory);
/* Change to the types you want */
$required_types = array(".gif",".jpg");
while($MIMEfile = readdir($dir)) {
$extension = strrchr($MIMEfile,'.');
if(($MIMEfile != ".") ($MIMEfile != "..")
(in_array($extension,$required_types))) {
$filetype = filetype($MIMEfile);
echo "li$MIMEfile";
}
}
?
/ul
/body
/html
Note that this probably isn't the best way to go about things, but I've had
a quick root through the file() functions, and could find nothing (though I
didn't look too hard) quick and easy.
Have fun.

Re: [PHP] radiobutton

So, on a form with a Radio button asking which you prefer, the one that
they've voted for before is the default button to be checked.

The browser will prompt them to identify before it allows files from a protected directory to be included. James, are you sure about this? Afaik, no user authentication applies to PHP include() calls. This would require PHP to integrate much closer with Apache than I think it does (and makes sense). Hi Ben, I'm not positive, (btw, what does Afaik mean?), but I'd assume any request to files that are inside a directory that has an htaccess file would be ignored by anything until the username and password have been included (I've used a PHP include on files before, which refer to files such as jpegs and gifs that reside in a protected directory, and I've run into the problem of having to authenticate before the images are displayed). There's a good chance I'm wrong, but I'll be sure to double check tomorrow morning. On another note, I seem to have problems with opendir() and readdir() (which one of the two I'm not sure). A simple script I've written will list all files in a directory I specify on one server, yet the same script (with the document root changed accordingly) will return nothing with the other. Both servers are running the same version of PHP (4.02). It's probably something simple I've missed, though I'm sure that the CHMOD settings are the same, and I'm getting no script errors. Any ideas?

[PHP] Querying MySQL using 'AND' / 'OR'
Hi Guys, Quick question.. I've managed to write a function (thanks to help from people earlier in the week) which queries an admin table. There are currently four fields in the table; id, username, password, and 'site', where the 'site' means a subdirectory of my site that the particular admin user is allowed acces to change things in Now, each 'site' user is allowed access to only their site, but, being the owner of all the 'sites', my field contains the word "all." So, I used this to determine whether the user (when logged in) is firstly an administrator, and secondly what area of the site they're responsible for: $sql = "SELECT * FROM table WHERE username = '$username' AND password = '$password' AND site = 'theirsite' OR site = 'all'"; Now, as you can probably see, the table is querying whether the table has a row with fields: username, password, site OR Just a row with the field containing "all." So, without writing some if statements, is there any way of rewriting that $sql check so that it checks whether the user is an admin of either the individual subdirectory, or all of the sites? Like username: foo password: bar site: all or username: foo password: bar site: subdirectory .

[PHP] Outputting specific HTML for table tag.
Hey all. well, here's (probably) an easy question from me again (surprise
surprise).
Here goes: I'm putting together a photo gallery for some friends of mine
who own a nightclub, and who want to update photos themselves. I know
there are scripts available to do the job, but I'd like to have a go at my
own.
Most of the stuff I can handle, but I just need to know what code I might
use for returning table cells correctly. Let's say, for example, there are
5 photos that need returning to one of the photo pages, and I have the
photos in rows of three; Obviously, there'd be an empty table cell. And
I'm not sure exactly how I get the results back into rows correctly
anyway... Bullet points and whole table rows are fine, but table cells?
Hrms.
Anyway, here's how I might've started writing the code, if I hadn't realised
I should ask for help first ;) :
?
// Connection code
$table = "table border=\"0\" /* Yadda Yadda */ ";
while($row = mysql_fetch_array($result)) {
$row = $photo['photo'];
$table .= "trtd$photo/td"
$table .= "td$photo/td/tr";
}
$table .= "/table";
// End Crap programming.
?
So. Any takers? :)

Ah, so you can constantiate (right word?) the query?

[PHP] Two little questions
OK, this will be laughably easy for you guys.
I want to write a function (until now, I have been heavily repeating code,
but it's time to trim everything down.)
The function basically needs to check that username and password have been
entered, and then check them against mysql data. All I am unsure of is the
format for the function... is it like this:
function CUP (
if ((!$alias) || (!$password)) {
header("Location: login.php");
exit;
}
);
And reference it later with CUP(); ? Don't worry about the MySQL side of
things, I just need to know how to lay out the function. Oh and if I can
put anything I want in the function.
Also, if I wanted to perform a search of a column in a mysql table for
"places", would the Syntax be something like this:
$sql = " SELECT * FROM table_name
WHERE place = LIKE \"$searched_word\" ";
?
Thanks in Advance,
James.

[PHP] Searching a MySQL database?
Can anyone tell me what I would use to query a MySQL database in a search? If the search field, was for example, a variable like "town", would the results page use something like this? : $sql = " SELECT * FROM table_name WHERE towns = \"$town\" "; I remember seeing someone post something like this: $sql = " SELECT * FROM table_name WHERE towns LIKE \"$town\" "; so if the search word is not EXACTLY like a row in the database, it may return results to partial words.

[PHP] Another q, this time eregi_replace
I'd like to be able to trim out some html tags, but only certain ones. I've
used eregi_replace before and have some replacements running on some
scripts...
Some of the help pages and user notes on the quick reference functions have
given me good examples of how to go about it. One thing I'm interested in,
though, is the syntax that's used to determine what the link URL is and the
link name... I think I saw it as:
//0 for the URL and then //1 for the link. Like this (poor code, I
dunno whether I've even got the right delimiters):
eregi_replace("/a href=\"//0\"///1///a/\","//1",$string);
I'd like to strip out everything but the link name, so if someone inputs:
a href="http://www.php.net"PHP!/a
It replaces it with:
PHP!
Thanks, again. I seem to be asking a lot of questions today, hehe ;)
James.

Re: [PHP] Searching a MySQL database?
You've basically got it... the advantage of LIKE is that you can add wildcards to specify what can be different... towns = '$town' ...and... towns LIKE '$town' ...are essentially the same without the % wildcard character. Thus, towns = '$town' ...is much different than... towns LIKE '%$town%' How different are they? I'm not even sure what a wildcard is?

Re: [PHP] Searching a MySQL database?
Here are some queries of the above table with their results bases='Ft. Worth' returns record 1 bases LIKE '%Worth%' returns record 1 bases LIKE '%Ft.%' returns 1 2 bases LIKE '%' returns all records (in this case, 1 2) See? That makes perfect sense.
