[PHP] Algorithm: Limiting Large Numbers of Pages to 10 visible
Hi,
I need an algorithm for paging. If I have 100 pages of results, I only
want to show
Prev 1 2 3 4 5 6 7 8 9 10 Next
Where I limit the number to 10 results of pages, but I cannot figure it out
for the life of me.
for ($i = $page; $i = ($page+10); $i++) {
if ($i != $page) {
echo a href=\$PHP_SELF?catid=$catidpage=$i\$i/a ;
} else {
echo $i ;
}
}
echo a href=\$PHP_SELF?catid=$catidpage=$i\/a ;
echo a href=\$PHP_SELF?catid=$catidpage=$num_pages\End/a ;
}
But what I need to do is not show pages that aren't there, and I'm
hardwiring it to show
10 whether they exist or not.
I've got to believe that there's a really slick way of doing this. I've
searched the usual
places (weberdev.com, devshed.com, zend.com) but there's no really good
keywords,
and when you search on 'paging you get too many results to be useful
Thanks in advance,
Lara

Re: [PHP] HTTP_POST_VARS: Data there, but can't get to it
My bad for typing it in from memory. I'd retyped it in a few times, so I
thought i had it perfect. Here's the exact code:
print_r ($HTTP_POSTVARS); // yeilds the array that I pasted down below
if ($flag==process)
{
$whatdo = $HTTP_POSTVARS['whatdo'];
print_r($what_do); // blank
.

$whatdox = $whatdo[$x];
print $whatdox; // blank

Hi,
I'm having some difficulties accessing HTTP_POST_VARS
The original form has a table where each row has a set of 3 radio
buttons name=whatdo?php print $x?[] where $x is the row counter.
(I'm using PHP to pull info into a table, then the user manipulates
the info, and it places the info into 2 other tables depending upon what
the choice is for the 3 radio buttons).
So, on submit, it reloads the page, and I pull in all of the areas. All
work except the radio buttons.
I've tried:
$submitted_vars = $HTTP_POST_VARS;
$whatdo = $submitted_vars[whatdo];
---
and
$whatdo = $HTTP_POST_VARS[whatdo];
--
but when I do a print_r($whatdo)
it's blank
When I do a
print_r($HTTP_POST_VARS)
I get
Array ( [whatdo] = Array ( [0] = load [1] = delete), [other
stuff])
What am I doing wrong :-) How do I access this data? It's so
frustrating
since all the rest of the postvars are working, and I can see that the
data's there in the HTTP_POST_VARSI just can't get to it. (pun not
intended)
Thanks,
Lara

Re: [PHP] HTTP_POST_VARS: Data there, but can't get to it
Just an addendum, I changed it from radio buttons to a pop up menu
p
select name=whatdo[] id=whatdo
option value=load selectedLoad/option
option value=deleteDelete/option
option value=changeChange Category/option
/select
/p
Again, if I print_r (HTTP_POST_VARS), I can see the Array ( [whatdo] =
Array ( [0] = load [1] = delete), [other
stuff])
but I cannot access it. I'm doing the same exact syntax for the image
name=image[] which works perfectly.
I can find nothing on this in the documentation or any of the other
wonderful books websites out there.
Please, what am I doing wrong in trying to access the HTTP_POST_VARS?
Thanks,
Lara

Re: [PHP] Having trouble with PHP exec function calling CGI program
Hi, Tony, I'm a middlebie, and I have the same problem. From the archives, I found the following suggestions from Richard Lynch: Does it work perfectly from the command line if you su to nobody (or whomever PHP runs as) before you execute it? Is it world executable? Does it access resources such as PGP key-rings that nobody can/cannot access? Are you sure you have the path correct? In my case, the answer is yes to all of the above (except for su'ing to nobody since I can't do that on this client's server). I've also discovered that it's usually a path/permission problem unless the server was built in 'safe mode' in which case, no script can be called. I added in `date`; to see if I could execute anything nothing happened, so I fear this. Now all I need to do is read up on suid in the PHP manual.Thankfully, this is just a tool for the client, and not something the world will see. Any other suggestions?

[PHP] How to unsubscribe
I hope you all enjoy this as much as I did. Lara Subject: How to unsubscribe from the list. :) You see, all of those to unsubscribe, do this. instructions at the bottom of the emails sent through this list are wrong. We only put those there to confuse everyone so that they will never leave the list. Since you've obviously got more intelligence than to follow instructions from the list owner ... here are the *REAL* instructions on how to unsubscribe: 1) Go to A HREF=http://www.dictionary.com/;www.dictionary.com/A and look up the word unsubscribe. 2) There is a hidden link right above the third word in the definition.click it. 3) That link will take you to Langley (US Security System). 4) Enter the launch code 345897349 to send a missile to 42 degrees north latitude, 98 degrees east longitude. 5) Right before the missile lands, there will be a flash on your screen with directions on how to build a model airplane. 6) Print those instructions and build the plane. 7) Take the plane to the roof of your building and fly it. 8) It will land on the sidewalk on a loose slab of concrete. Pick up the concrete and put it in the nearest trash can. 9) Dig in the dirt under the concrete and there will be a red button. If you push the button, you will unsubscribe yourself from this list. - Lara J. Fabans Lodestone Software, Inc [EMAIL PROTECTED]
[PHP] ereg parse error problem
Hi, friends,
I'm receiving a parse error on the if (ereg... )
lines of this code. I looked at the online manual and modeled my two
ereg's after it.
When I kept getting parse errors, I decided to copy the original from the
manual into
my code, and it too received a parse error.
Can someone please help me resolve this?
Thank you,
Lara

[PHP] Was: ereg parse error problem Now: RegEx Plea for Help
Thank you, Phil, for fixing that. Obviously this snippet is trying to be a
smaller test case for a much
larger problem. It looks like I'm pulling *all* of the img and a href
from the $string and I don't
want that at all. I just want one of them.
So, my return is:
image source:http://www.123posters.com/images/m-mase01.jpg; alt=Mase
Necklace/a img src=http://www.qksrv.net/image-297915-361662;
height=1 width=1 border=0
href: http://www.qksrv.net/click-297915-361662; target=_top img
src=http://www.123posters.com/images/m-mase01.jpg; alt=Mase
Necklace/a img src=http://www.qksrv.net/image-297915-361662;
height=1 width=1 border=0
I mistakenly though it would stop at the second quot;, but it's going all
the way to the end. Is there any way to tell it to
find one instance instead of the globalizing like it's doing?
I'm going to play around with a few more things, but after staring at the
code for 4 hours, my brain is fried.
Thanks,
Lara
