Re: [PHP] Easy question - delete strings from the beginning of space...
to get rid of potential double spaces after the explode, you could do:
foreach ($words as $word) {
if (!empty($word)) {
$first = $word;
break;
}
}
echo $first;
This will always return the first word.

Hi,
I am working on a page the displays the output of a query in a table and

The label is called Notes and the corresponding field in the database

So I wrote the following script where I think I am saying if memberNotes
returns any value then print the output of $notes in the table cell
where it is called, but nothing happens and the output of $notes is not
displayed regardless whether memberNotes has any output.
?php If ($memberNotes =='1') {
What is $memberNotes supposed to contain? If it is supposed to contain notes
on members then surely it can't be '1' all the time?
I think you probably want:

Thanks for responding! Yes the memberNotes database field only

the entire field and label when their was no relevent data.
I made the change you suggested, but the field label does not show up
when memberNotes contains data. As follows is the current script. Is
what what you suggested?
?php If ($memberNotes) {
$notes = div align=\/left\/font
size=\/-1\/bNotes:/b/font/div;
} else {
$notes = div align=\/left\/font
size=\/-1\/b/b/font/div;
}
?
What are those forward slashes (/) doing in $notes? Try getting rid of them,
they don't look very HTML to me :)
Also try echo($notes) OUTSIDE of a table construct to see what it contains.

I used echo($notes) at the bottom of the page and the output of $notes
prints reardless of whether or not the db field $memberNotes contains
any data. It seems to me that $notes is always acting as if $memberNotes
always contains data. Is their some way to invoke $notes only if
$memberNotes returns any data?

RE: [PHP] Easy Question -- Show/ Hide text based on output of query
Thanks for all your help, but I figured out what I did wrong
I was calling the memberNotes field using
echo $get_detail-Fields(memberNotes)
so when I replaced $memberNotes in the script with
$get_detail-Fields(memberNotes) it worked like a charm
If ($get_detail-Fields(memberNotes)) {
$notes = div align=leftfont
size=-1bNotes:/b/font/div;
} else {
$notes = ;
}
Dumb error on my part.
Thank you very much for your patience,

RE: [PHP] Easy Question
When you write a php script to access a database,edit records, etc., is the entire thing 1 giant PHP page or a bunch of different ones? A giant one If it can be written both ways, which is the better way to do it? Depends how big is your 'giant'. It is all about your coding style, but it is advisable not getting over 500 lines - saves you a lot of developing time. However, too many (7, 10, more) includes will become noticeable. Not all is said by this, there are so many reasons why use this or that, but generally it is up to your own coding style.

I tend to write based on function:
userland.php
adminland.php
whatever ...
then include() the bits where the $vars indicate:
if ($do_detail)
include('detail.php');
And, of course, underneath is the common thingys:
require(class.html.php);
require(class.forms.php);
require(libsql.php);

Re: [PHP] Easy Question
My Database functions are all wrapped up in an easy to use class. The
methods look something like this:
$db = new DB;
$q = SELECT * FROM ATable;
$db-query($q);
while ($db-next_record()) {
$db-p(SomethingOrOther);
}
For the PHP script itself, the content management system I wrote up uses
case statements in a single file engine and multple includes.
for example:
switch($func) {
case(news):
include(/news/news.inc);
break;
}
and news.inc may contain:
switch($task) {
case(add):
include(/news/news.add.inc);
break;
case(del):
include(/news/news.del.inc);
break;
default:
include(/news/news.view.inc);
}
and then each would contain the actual code. It worked really well for a
couple of reasons. For starts all the includes started as requires for
testing purposes. If I edited several files but maybe didn't test them all,
it'll will kick out any parse errors or warnings -- also useful since I've
got another person working with me. Then when the site went live, I changed
them to includes (well actually had to change a bunch of them part way
through when I ran out of memory *s*).
Also the code is very modular. I know what each file does and so does my
partner who isn't a php programmer but may need to edit the HTML portions a
little. Each file is clearly named as its its funciton so he knows where to
look if there is a problem with a pages appearance.

RE: [PHP] Easy question...grabbing variables...
If you want to pass more than one variable via GET, you need to use an ampersand () character for the variables after the first one (still using a question mark for the first). So in your case, you can have this: http://wwbl.hyrum.net/send_email.php?to=4from=25 Then within your send_email.php script, you can access $from which will have the value 25 upon entry to your script.

if they all test true in the first place, the () are kinda obsolete. :)
