Please show a little more code, as it looks to me as though this should work

Specifically: how do we know what is in $c? how do you know the array_search

Re: [PHP] JPEG info needed
I *have* tried, Richard. It is not returning the state of the file. Files that Irfanview recognizes are prograssive, your example code does not. Looking at C code in gd-2.0.33/gd_jpeg.c downloaded from http://www.boutell.com/gd/ there is a comment: /* REMOVED by TBB 2/12/01. This field of the structure is documented as private, and sure enough it's gone in the latest libjpeg, replaced by something else. Unfortunately there is still no right way to find out if the file was progressive or not; just declare your intent before you write one by calling gdImageInterlace(im, 1) yourself. After all, we're not really supposed to rework JPEGs and write them out again anyway. Lossy compression, remember? */ The docs at http://www.boutell.com/gd/manual2.0.33.html#gdImageInterlace say gdImageInterlace is used to determine whether an image should be stored in a linear fashion, in which lines will appear on the display from first to last, or in an interlaced fashion, in which the image will fade in over several passes. By default, images are not interlaced. (When writing JPEG images, interlacing implies generating progressive JPEG files, which are represented as a series of scans of increasing quality. Noninterlaced gd images result in regular [sequential] JPEG data streams.) A nonzero value for the interlace argument turns on interlace; a zero value turns it off. Note that interlace has no effect on other functions, and has no meaning unless you save the image in PNG or JPEG format; the gd and xbm formats do not support interlace. When a PNG is loaded with gdImageCreateFromPng or a JPEG is loaded with gdImageCreateFromJpeg, interlace will be set according to the setting in the PNG or JPEG file. -- To me that means the code authors cannot determine what the state of the file is, and are not returning a state they cannot determine. Gerry On 1/25/07, Richard Lynch [EMAIL PROTECTED] wrote: Re-read the docs more carefully. The second arg is optional, and it returns the PRIOR state of the interlaced-ness (or progressive-ness for a JPEG). Standard computer-science function trick to return prior state when altering state, and to simply return state if the second arg is not passed in. So if you do not pass in a second arg, you should be getting the state of the JPEG. Try it.

Re: [PHP] Preventing double-clicks
Jay,
I use a technique to prevent hitting the back button and
resubmitting data. I use a 2-script process, one with the form and
submit button (I set a session var here), and a second form (the
action script). The action script makes sure the session variable is
set, processes the info, then clears the session var. If the session
var is not set, an error is displayed.

If the process sees the unique data and a timestamp sometime within the

is so important. The first data returned is the correct data.
My confusion is in this (as I have mentioned in the past couple of

Kevin, You can do it with a Unix timestamp, but that would just confuse the issue. Have you considered using two fields instead of one?

However, if you aren't, then getting MySQL to dump a file becomes very problematic with respect to getting the right permissions to accomplish the task. So, I found a way around it. I am sure that others have thought of this before me, so I'm not claiming credit and I am sure that this solution is obvious to some -- but, it's just that I searched literally hundreds of posts and spent considerable time without finding an answer. The following is the result of my tinkering. So here goes: First, on your site create a file called my_image.png Second, give it 777 permissions. Third, in your code after opening the dB, grab the image from MySQL: $dbQuery = SELECT image; $dbQuery .= FROM $your_table ; $dbQuery .= WHERE image_Id = $pageNum; $result = mysql_query($dbQuery) or die(Error: .mysql_error()); Forth, drop the image into a variable: $fileContent = @mysql_result($result, 0, image); Fifth, create an image from a string (a great function here): $original=imagecreatefromstring($fileContent); Sixth, save the image. imagepng($original, my_image.png); And Bingo, the image is now the my_image.png file.

Query the backend database and generate a page listing all the staff members in table format that has name, title, phone and office address. Staff name should be a link. Clicking the link should query the database again and use the information retrieved (e.g. projects, educations, etc.) to generate a page for each staff member. A staff list page can be generated pretty easily. Now my question is how to keep the staffID (although it is not shown on the staff list page, but is queried along with name, title, etc.) so that when a staff name is clicked, his/her staffID will then be used to query the DB for personal information. Anybody have any handy working examples to give me some hints? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Floating numbers truncating to two digits without rounding
sprintf creates a string ready for you to manipulate. So does number_format. Pick whatever is best for your purpose. See http://uk2.php.net/manual/en/function.sprintf.php and http://uk2.php.net/manual/en/function.number-format.php for more info.

Problem is in the way Apache/PHP see stuff. If i include /somefile.htm in html, it means somefile.htm wich is at site root dir. In PHP it looks like it means somefile.htm at SERVER root dir.

[PHP] \|/ $PHP_SELF
Does $PHP_SELF always get's the path of the document it resides in even if the
document is an include?
I'm trying to set one of those breadcrumb path navigation scripts and I don't want to
copy the
script to every directory, I just want to include it in my header.inc.
As a result I only get the home directory link that way.
I tryed using a variable like $string=$PHP_SELF; then in the script I replaced the
line:
$str=$PHP_SELF; with $str=$string; , but it turn out as an empty variable.
Here is the original unaltered php:
$site = http://.$HTTP_HOST./;;
//$site = http://site.com;;
$str=$PHP_SELF;
ereg(^(.+)/.+\\..+$, $str, $part);
$str = $part[1];
$str = substr($str, 1);
$label = array(home=Home,
anunciate=Anunciate,
encuentreMedico=Encuentre un Medico,
anunciateHospital=Anunciate Hospital,
anunciateMedico=Anunciate Medico,
article=Article,
encuentreHospital=Encuentre un Hospital);
if (ereg('/', $str)){
$arr = split(/, $str);
$num = count($arr);
for($i=0; $i $num; ++$i){
echo( a
href=\. $site . $arr[$i] ./\.$label[$arr[$i]]./a);
$site = $site . $arr[$i] ./;
}
}elseif (ereg([a-zA-Z_]{1,}$,$str)){
$arr = $str;
echo( a
href=\http://.$HTTP_HOST./.$arr./\;.$label[$arr]./a);
}else{
echo();
}

[PHP] Results of survey I asked
Earlier, I asked some questions about what you use in developing PHP applications. First, the questions, and then the answers: Questions 1. Code libraries used: a) Metabase (for database abstraction) b) PHPLib c) PEAR d) BinaryCloud e) other 2. What code editor do you use? 3. How many are using templates, and if so, are you using a template framework: a) PHPLib b) Smarty c) other? Answers (number of respondents in brackets) 1. adodb (1) BinaryCloud (1) A mixture of PEAR's database abstraction, PHPLIB's template class and my own libraries and classes (1) 2. UltraEdit (1), DreamWeaver 4 (2), AceHTML4 Pro from visicom.com (1), Homesite (2), vim (1), FrontPage (1), PHPCoder http://www.phpide.de (2), emacs (1), TextPad (1), ConTEXT (1), EditPlus (1) 3. Smarty (1) Summary: not a huge statistical sample, but interestingly there were hardly any duplicate responses. Also, it seems using published templates and code libraries is not that popular, i.e. most people are writing their own code from scratch. Gerry
[PHP] Feasibility of using XML, PHP for a database-driven web application
Hello, I've been doing some research to assess the feasibility of using PHP and XML for a web-based database-driven application. From what I've read, it seems that presently the costs of using XML outweigh the benefits. Here are the costs I see: 1. XML standards are still maturing 2. XSLT is complex and difficult to understand 3. Their is minimal support for XML in relational databases, and none for MySQL 4. PHP's XML tools are still in their infancy 5. The processing time to go from SQL to XML to HTML via XSLT is often high. The benefits? 1. Greater abstraction between data, logic and presentation which can be easier to design, develop and maintain. Your thoughts?

[PHP] What tools do you use to develop PHP?
Hi, I'm putting together a PHP development framework for our small group. We have worked on a couple of small apps, so now it's time to do things a little more methodically, i.e. make life easier for everyone. :) So, I scanned the web and found quite a few options for code libraries, and a few for PHP code editors. I'm interested to know what tools / libraries people prefer - 1. Code libraries: a) Metabase (for database abstraction) b) PHPLib c) PEAR d) BinaryCloud e) other 2. What code editor do you use? 3. Source code control. CVS appears to be the only real option here.

[PHP] Compiler advice please!
Hi this is probably of the scope of the list since it is a c++ question. (sorry) I'm trying to learn a few things about c++ and I'm using gcc on my Linux box. The problem I encountered is with the floating point manipulation classes or functions like fixed and showpoint, I get a compile error saying they are not declared. I triyed the gcc.gnu site but I could not find a support maillist like this one. After endless fruitless searches on the web I decided to give you a shot since you have answered many of my PHP questions and I know some of you do a lot more than just PHP related development. Could someone point me in the right direction please, maybe a site or mailgroup where I could ask about this? Thanks in advance and sorry for the inconvenience!

[PHP] Calling a function that resides elsewhere
I hope you understand:
It is too long to include here so I'll give you an idea.
file.B

?php
$all_cats = "1, 2, 3";
function html_options($output,
$values = NULL,
$selected = NOT_NULL,
$first_option_output = false)
}
return($html_output);
}
echo"select name=\"cat\" size=\"1\"";
//-cats
$cats = explode(',',$all_cats);
//--values
$cats_vals = explode(',',$all_cats);
print html_options($cats, $cats_vals, $selected, "--Select one--");
echo"/SELECT";
?
file.A code:
?php
$connect to db;
$get result;
$cat = $row["cat"];
$selected = "$cat";
---
include ("file.B");
---
done
?
From here on I get the menu with --select one-- option first then 1, 2,
3, but it ignores the fact the I told it $selected = "$cat". I figure it
has to do with including the function file instead of having the
function inside of "A". How can I call file.B from different files and
have it accept the variable $selected from such files?
Thaks in advance:

[PHP] PHP+MySQL SEARCH
I got this from a book but given the fact that it would only search for
one type of information I modified it and it works great, but I wanted
to know what you think about it if anything. Could an array be maid to

$query1 = "SELECT * FROM FISH where ID LIKE '%$search_text%'
OR name LIKE '%$search_text%' OR Category LIKE '%$search_text%' OR Color
LIKE '%$search_text%' OR Size LIKE '%$search_text%'";

[PHP] File_exists function question.
Hello everyone:
I'm trying to build a table with the last row being a check function for
an image, where it checks if the item image exists in the image
directory and either echos "no image" or places a small icon of
something (I guess you could say Ebay style).
The problem is that the fuction checks for an image matching the first
row item id and then it copies the same result to the remaning item
rows weather they have images or not. I read that I could use the
clearstatcache() to clear the cache and start again but there must be
something wrong with the way I persive the use of this.
this is the code:
$fn = "directory/images/$id.gif";
if (!file_exists($fn)) {
echo "no image";
} else {
echo"img src=\"$siteurl/images/camara.gif\"";
clearstatcache();
}
Could anyone that sees what's wrong with this drop me a line?
Thanks in advance:

bucket = good
weight = 100kg
Colors = green, blue, red
and here is my php:
while ($row = mysql_fetch_array($sql_result)) {
echo"trtd";
echo $row["paint"];
echo"/tdtd";
echo $row["bucket"];
echo"/tdtd";
echo"form action=\"http://www.\" method=\"POST\"";
$Color = $row["Color"];
if ($Color == $Color) {
$option .= "OPTION value=\"$Color\" selected$Color/OPTION";
} else {
$option .= "OPTION value=\"$Color\"$Color/OPTION";
}
echo"select name=\"Colors\"";
echo "$option";
echo"/select";
as you can see I end up with a select menu with this "green, blue, red"
as the only option.
is there a way I can tell php3 to break it down at "," so I can actually
have a drop down menu
Thanks ahead:

Can't the
index.php script pull content from any number of different directories?,
eg:
index.php?page=Yarns/stuff
index.php?page=Rovings/stuff

Well the thing is that there is probably a few ways to do this and I
thought of the way you just presented to me. I can see a redirect to
page=Yarns/stuff. What is stuff by the way? Where do I find this script?
My way of doing this (novice way), is I made my index.php and added
variables to call the header, navigation, content and footer. The
content is loaded with a variable like include "content.html"; not much
to it but at this point is useless if I have to do this inside every
directory (eg. Yarns/index.php3) add all the variables and also place a
content.html in every directory. I can see I'm doing it all wrong now.
All I need is to be able to learn how to load everything from a script
and how to call the script with a URL to the directory.
eg. ? if (Yarns/)
{
include "header,nav, fetch content,footer";
else "?";
}
?
a href="http://mysite.com/Yarns/" Yarns/a
Right! I can see this would not work, because I'm missing some things.
Don't worry if you got it wrong, I don't know if you did! I wish it
where this simple anyway.
