Hi all ,
I have a code below :
function goToPageSelect($selectname,$totalItems){
$_logger = new Log4jLogger();
$_logger->logdebug("starting ..goToPageSelect()");
$_logger->logdebug("starting ..goToPageSelect()", $totalItems);
$selecthtml = "Go to Page:<select name=\"$selectname\"
class=\"inputfield\" onchange=\"javascript:gotoPage()\">";
for ($index=0;$index<$totalItems;$index++){
$value = $value + 1;
$selecthtml .= "<option value=\"$value\">$value</option>";
}
$selecthtml .= "</select>";
return $selecthtml;
}
It will produce the html tag as shown below:
<script language="JavaScript">
function gotoPage(){
var urlpath = "../listflag.php?start=&pageID="+3;
document.forms['listfrm'].method = 'post';
document.forms['listfrm'].action = urlpath;
document.forms['listfrm'].submit;
}
</script>
<form name="listfrm">
Go to Page:<select name="pageid" class="inputfield"
onchange="javascript:gotoPage()">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</form>
I tried using onchange in the select tag,but it did not work. It go to
the javascript but the form is not submitted .
Anyideas why?

In gotoPage() you're not referencing the value of pageid
(document.forms['listfrm'].pageid.value). More of a JavaScript question,
are you a member of a JavaScript list?

Hi Ryan,
I use Log4jPhp to log any debug value.
I think it is better than using echo or print method.
Thanks

a debugger would be needed to single step through the code,
although how much help a debugger will be if someone doesn't
understand php's OO principles [very well] is questionable,
generally one has to have a good idea of what the code is meant to
be doing in order to make head/tails of the debuggers output.
maybe we can help in explaining what your script does?

Personally, i think the best one is Zend debugger. It's integrated on
the Zend IDE, and let you debug remotely, from a server. The problem
aside, is that is paid and closed source, neverthless is the best IMHO.
You may give it a try: www.zend.com/products/zend_studio

:) Your name just came to mind when I thought of OO
as I saw a few of your threads before bitching (no
disrespect meant) about PHP5's OO, and future
compatability

Well, the script runs without a problem, so he can see
what the output is and what it is accomplishing, I
guess he just needs to hit the books a bit harder.
I learnt (brushed up) OO/class programming via an
online PHP site, they had some really good articles,
but just cant remember the site name :(

Trust me, it would take longer for me to write down
the whole thing than actually show the guy's mum and
make her understand!
Writing descriptions for a script is always a PITA.
Cheers!

Hi
Can anyone help with this ? its checking the $_POST and seeing if any of the
items begin with answer_,
if the do it should remove it from the beginning and place it into
$value_new.. does not seem to work though...
foreach($_POST as $qid => $value) {
$findme = 'answer_';
if(stripos($value, $findme)) {
$value_new = ltrim($value);
print "$value_new<br>";
}
}

stripos should be strops and would look for a numeric value, not what
you want. You want strstr I believe
foreach($_POST as $qid => $value) {
$findme = 'answer_';
if(strstr($value, $findme)) {
$value_new = ltrim($value);
print "$value_new<br>";

Afternoon all
I need some help here with a problem on dynamic radio buttons.
I have a script that calls a database for a list of questions. The questions
are returned and each question needs to have 5
radio buttons assigned to it. The radio buttons are a score of 1 - 5 (1
being bad, 5 being good)
For example
1 . How would you rate your vacation? 1 2 3 4 5 <--- those are the radio
buttons.
2. How would you rate your dining at the resort? 1 2 3 4 5
Ok so I have all the questions being returned, I was thinking when creating
the radio buttons as follows
<input name="<?php echo $row_get_question_list['id']?>" type="radio"
value="1" />
<input name="<?php echo $row_get_question_list['id']?>" type="radio"
value="2" />
<input name="<?php echo $row_get_question_list['id']?>" type="radio"
value="3" />
<input name="<?php echo $row_get_question_list['id']?>" type="radio"
value="4" />
<input name="<?php echo $row_get_question_list['id']?>" type="radio"
value="5" />
The input name for each radio group is the questions id from the database.
If there are 50 questions you would have 50 radio button answers submitted.
How are you going to identify the radio buttons being submitted as they are
dynamic? and also I would need to be stored in the
session data as they might want to go back / forward a page.
So basically I need to go through each $_GET item, identify it as a radio
submission and put it into an array.
Has anyone done anything similar before / or can point me in the right
direction??
Kind regards
Chris
You won't get all the radio buttons sumbitted.
You will have only the checked buttons.
So for every question's ID you will have the radio button that was checked.
Just do some testing.
Try echoing the $_POST array after you submit the form.
var_dump($_POST);

Sorry, I have to respectfully disagree.
I was converting all indexes to string indexes, and simply using
"zend_hash_update" to re-constitute the objects and they simply did not
work. When I scanned indexes strings to test for purely numeric content,
and when true, used "zend_hash_index_update" instead, it worked.
This behavior appears different in 5.1.X from 4.x, I can't explain it
100%, but I know that this change fixed the problem I was seeing.

a quick test on 5.1.1 shows this not to be the case
(at least at the userland level):
# php -v
PHP 5.1.1 (cli) (built: Jan 18 2006 17:41:38)
Copyright (c) 1997-2005 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2005 Zend Technologies
# php -r '$r = array();$r[0] = "test";var_dump($r[0],$r["0"]);$r["0"] =
"test2";var_dump($r[0],$r["0"]);'
string(4) "test"
string(4) "test"
string(5) "test2"
string(5) "test2"
seems the perceived problem is being caused by something else?

Hi folks,
well, I have a really dumb question:
I have the following script at http://www.tisys.org/misc/test.php:
<?php
echo $_GET['license'];
?>
Now I call it like this:
http://www.tisys.org/misc/test.php?
license=0701770160811371731660412452242420381052542100071831272071031621
17160180165221170166096217228128
And in fact, it echos the whole, long GET-string!
Now i have the following script a tttp://www.tisys.org/misc/
ol_license.php:
<?php
if ($_GET['license'] ==
"07017701608113717316604124522424203810525421000718312720710316211716018
0165221170166096217228128")
{
echo '1';
} else {
echo '0';
}
?>
I launch it like:
http://www.tisys.org/misc/ol_license.php?
license=0701770160811371731660412452242420381052542100071831272071031621
17160180165221170166096217228128
And it returns a 1, which means: The strings match. Now I call it like
http://www.tisys.org/misc/ol_license.php?
license=1701770160811371731660412452242420381052542100071831272071031621
17160180165221170166096217228128
that is, I have changed the first number of my GET-String from a 0 to
a 1 and indeed, the script returns 0, meaning: The scripts don't
match. *HOWEVER*, no I call the script like:
http://www.tisys.org/misc/test.php?
license=0701770160811371731660412452242420381052542100071831272071031621
17160180165221170166096217228129
that is, I have changed the last number of the GET-String from an 8
to a 9, and interestingly, it returns 1 this time, which means the
strings do match, which, however, they don't.
My guess is that PHP only sees / compares the strings up to a certain
position. Is this possible? And if so, is there any way around this,
so that my whole string is seen?
Greetings and thanks in advance,
Nils

Maybe it's interpreting something as a number somewhere. Did you try
using === instead of == for your comparisons?
Regards, Adam Zey.
PS: Why is your license key so insanely long, and why doesn't it use
alphanumeric characters to reduce the length?

Hi,
This is not really a problem, more like a slightly OT
question.
Recently I have been testing some "CMS/carts/BB
boards" and other related software, sometimes at the
end of the page the software outputs the time it took
to generate the page and the number of database calls.
I have seen some scripts give the number of database
calls in the hundreds (from 100 - 400) just to
generate one single damn page.
Isnt that just too much?
Or am I blowing smoke and MySql can handle that
without a sweat on a shared hosting environment? (with
say....100 page requests per minute?)
Thanks!

It's usually a sign of poor programming and/or purist OOP programming.
When I say purist OOP programming some idiot retrieves X topic IDs from
the database in 1 query, then proceeds to execute X queries in the
constructor of the object to build the actual topic objects, then each
of these stupid constructors then proceed to build their children
objects (replies) which they do by doing a single query that returns Y
children IDs, and then it loops over these and builds the objects via
the constructor which again makes another Y queries, and of course those
stupid objects go and create their children. I saw one really retarded
implementation of this kind of system where an excess of 20000 queries
were issued to the database -- on a homepage nonetheless :/ I think it
was a testament to MySQLs speed that it performed within a reasonable
timeframe (under 3 seconds). Either way, such an application will never
be scalable such that the database server resides on a different
computer than the webserver (even over a LAN).

MySQL can probably handle it. But try not to do programming like that
yourself. Stuff like that gives PHP a bad name.

Rob.

That IS retarded, I wonder why someone would want to
do that.

MySql is a workhorse... def one of my top 3 DBs (I
came into LAMP from Java/Oracle)
I see you have seen some of the apps I was talking
about, even though I have not mentioned any names to
offend anyone.
I was curious about this because I am working on a
project (with other team players) and we have a way of
building something with either lots more (complicated)
code and fewer database calls or less code and
multiple tables.
If we take the second option (multiple tables) I am
talking about maybe 15 database calls per page, and
the site will get around (i guess) 300-750 requests
for a page a minute at is peak.
The good thing is it will be running on a dedicated
server, sharing with around 5 of our other sites... no
exceptionally great traffic other than mentioned above
on the other sites either, plus most of the other
sites are plain html sites.

I wouldnt be going to those extremes, was thinking of
around 5-15 queries per page.
Think we'll have a problem?
Thanks!
