Are you doing a session_start() on all of the other pages?
attached mail follows:
It is in an include file which is included in all the files.
the first line in the file is session_start();
maybe it should be in each file rather than an include what do you think?

Thanks for your pointers Richard, you've given me plenty of ideas for when things go wrong as I continue to explore PHP and PDF.
As it turns out, my problem was a typo copied faithfully from 'Programming PHP'. For anyone else trying the example (Hello world in PDF, on p 234), make sure you use "application/x-pdf" in the Content-Type header, not "application/pdf" as printed in the book.
If this really is a typo, could someone let me know and maybe I'll register it with O'Reilly if they don't already know about it.
Typos happen in all books, especially technical books. Apart from this small error (?), the book is great and has really filled out the holes in my PHP knowledge.

Well, I wrote that, and it is not a typo. Your browser is simply misconfigured. If you install Adobe's Acrobat Reader, which these days is the de-facto standard PDF browser plugin, it will register itself as application/pdf. Same for every other PDF viewer on every platform I have ever tried.
So, if you want people to be able to view your page, you better use application/pdf and not application/x-pdf and fix your browser config while you are at it.

First off, I have to LMAO at "that would suck". So unexpected but humorus.
But seriously, this is why I suggest it be a config file option. Not a new way of doing things, to break old code. But something toggle-able.
Or, I'm sure the PHP parser could be made smarter to look for common 'assigments' that are supposed to be 'conditions'.
For example I seriously doubt that NOBODY EVER means to do
if ($x = 5) { }
That CLEARLY is supposed to be using a == and not =
And I'm sure there are other such obvious cases that the parser could check for somehow.
Just a suggestion. Thass all.

It depends on your form. If you have a "contact the admins" form, then they can find out your email. Or say you are running an AA help group and you provide a way for people to email each other through the web. Someone can type in a message and then your PHP script send out a message to each of the members, but the message is from your web site, not the person, so their identities are hidden, for privacy reasons. Now if I put in a contaminated Subject, I can get CC:d on EVERY email that the script sends out at that time. I can find out everyone's email address. How are you protecting the privacy of your users? > Since they *SENT* the email, that does not seem like much of an issue to > me.
It's not the content they would be after, it would be finding out the email addresses of the recipients.

It would just work each time they filled out the form.

But most forms do let people choose their own subject. And I don't have to upload the code anywhere, just provide a full http:// address to your form processing page. I can spoof HTTP_REFERRER if you are checking for that. Now if your authenticating or using a session, it may be harder.

Many ways to fix it, once you are aware of it.

But if you use mail($to,$subject,$message,$headers), then PHP should ONLY allow a SUBJECT: header to be set in the $subject parameter. Same thing for $to. It's not PHP stopping us from doing stupid things, it's PHP doing what it says it's going to do, only letting the value of $subject set the Subject: header and that's it.
This is something that 99% of the people out there aren't going to think about. Look at all the problems already with cross-site scripting. It's an easy fix, yes, once you know about it, but I think it could be better handled at the PHP core level.
Is there ever a need to let someone set additional headers in the Subject part of mail()? Why allow people the change to do it and have unwanted consequences when it's easily fixed for everyone?

I think you could do this with just two pages. Set the action of the form on
the first page to be the URL of the second page. Make the form displayed on
the second page dependent on the value passed from the first page -- the
value being the selection made from the drop down menu. Let the form(s) on
the second page do all the database submission.

Hi there, here is my problem
I'm using php to generate a dynamic pdf document and when ready send it with email. Since it takes few minutes to generate I start a new process with popen that makes the pdf like this
popen("./pdf.php \"".$outputarray."\" > /dev/null &", "r");
pdf.php then generates it and everything is ok but this new process takes so much cpu that the site is halted for these few minutes. My question... is there a way to set pdf.php-process to a lower priority? I've searched everywere and couldn't find it.
Please reply in email since I will miss it otherwise

What a mailing list! I very much appreciate the timely and constructive help. From all your responses, I was able to put together a solution for uploading files to a server that worked. Here it is.
I created a file called getfiles.php in which I put the form that the user uses to upload his file: (I've left the text and formatting out of this post)
<form enctype="multipart/form-data" name="frmUploadFile" action="storefile.php" method="post"> <input type="file" name="fileUpload" size="20"> <input type="submit" value="Upload this file" name="cmdSubmit"> </form> Richard, "size" is the size of the text box into which the selected file goes. I created another file called storefile.php that moves the uploaded file from the default temp directory to the assigned directory:
<?php // In PHP earlier then 4.1.0, $HTTP_POST_FILES should be used instead of $_FILES. if (is_uploaded_file($HTTP_POST_FILES['fileUpload']['tmp_name'])) { move_uploaded_file($HTTP_POST_FILES['fileUpload']['tmp_name'], "/home/sites/home/users/demodocs/web/ProjDocs/" . $HTTP_POST_FILES['fileUpload']['name']); } else { echo "Possible file upload attack. Filename: " . $HTTP_POST_FILES['fileUpload']['name']; } ?>
Note 1: The php manual, http://www.php.net/manual/en/features.file-upload.php, is confusing to us newbies in that it is not clear that there should be a variable file name in the path definition. Note 2: There must be a dot '.' before the '$' in the file name. I had omitted the dot, and accordingly got parsing error messages. Both of the above files are put in the web site root, /home/sites/home/users/demo/web
When I point my browser to getfiles.php the form appears and I can browse for files from my hard drive. When I upload the file, it goes to the default tmp directory and is then moved to ../demodocs/web/ProjDocs Note: I got permission denied errors until I fixed chmod for the /ProjDocs directory. Neither 755, 666, 766 nor 622 worked. What works is 777.
I'm using PHP 4.0.6 on a Cobalt RaQ4 with Apache 1.3.20

Hello Jason, It might work but I can not for the life of me figure out how to use it to get the data. Below is what I have so far but don't know where to go from there If I search for a word that is in $row_1 I what it return every line that it is in and there will usually be more than one. This is a virtusertable table for sendmail that I am searching. I need to retrieve data change data and delete data with this script. So far all I have done is separate the data so I can do something with it. I don't know maybe I am going at this all wrong if somebody has a better idea please let me know
function bs_file($filename) {
$fp = fopen($filename, "r");
if (!($fp)) {
return 0;
}
while (!feof($fp)) {
$temp .= fread($fp, 4096);
}
$arr = explode("\n", $temp);
return $arr;
}
$filename="./etc/virtusertable"; $file=bs_file($filename); for($i = 0; $i < count($file); $i++){ $value = $file[$i]; $arra = explode(" ", $value); <-this is searching on a tab $row_0 = $arra[0]; $row_1 = $arra[1]; $multi=array($row_0,$row_1); echo "$multi[0] $multi[1]<br>"; }

Hi, i have a problem with sessions. I use the trans_sid ('couse i don't like cookies) and everything worked fine... but when i insert ob_start("ob_gzhandler") to my script, to compress the output, the URLs don't get rewrited. Has anyone a suggestion for this prob? I have the entire of the output in a variable to rewrite something in it via regex, maybe someone has a regex for rewriting local links with the session-tag.

Hi all. I’m making a few dynamic menus that grab information from a MySQL DB. What I don’t know is how to print only one line of each. I don’t want a Drop Down List displaying 4 times the same line if the information is repeated in 4 rows in the same table. What I’m using is something like: $query = “SELECT * FROM tbl_name”; $result = mysql_quiery($query) or die(mysql_error()); $num_rows = mysql_num_rows($result);
<select name="select_name">
<option SELECTED>Select Something</option>
for ($i=0; $i<$num_rows: $i++)
{
$row = mysql_fetch_array($result);
print ("<option value=\"".$row[some]."\">".$row[some_else]."</option>");
}
</select>
This works just fine now that I don’t have 2 or more rows with the
“some_else” repeated. Is there a WHERE or something like that which I
can use for this?
Thanks in advancem

Well your problem is you're not doing ANY comparisons. Your if statements are assigning values. Not comparing...to compare you need to use == , not just =. With your current statements, each if statement will always be true, just the value of $a changes at each if.
<? $a="null"; if ($a=="dwa") { // one sign = so it is OK echo "OK"; } if ($a==true) { echo "OK"; } if ($a==false) { echo "OK"; //but it is not written!!!!!!! } ?>
Is what you need. Also for me boolean checks in my opinion are much simplier if you use 1-0 for the comparison (but use what you need, I don't know your entire code).
Sincerely,
Craig Vincent

Try the "SELECT DISTINCT" syntax in MySQL
From the MySQL manual: "The options [for the SELECT statement] DISTINCT, DISTINCTROW and ALL specify whether duplicate rows should be returned. The default is (ALL), all matching rows are returned. DISTINCT and DISTINCTROW are synonyms and specify that duplicate rows in the result set should be removed."
$query = "SELECT DISTINCT * FROM tbl_name";

Hello all,
I've just set out to build a PHP-based mail system that will be able to send HTML e-mails to a variety of mail clients. So far, I'm having moderate success: I can get Yahoo! and Hotmail to see the HTML, but not Netscape Mail or Outlook Express.
I was wondering, is there anything special I should be putting in my mail() call to achieve broad compatibility? I'm already sending a header that includes:
MIME-Version: 1.0\r\n Content-type: text/html; charset=iso-8859-1\r\n
Also, does anyone know of a list of mail client compatiblity levels with HTML e-mail?
Thanks, Alex Kirk

I am just getting started with functions, and have checked the manual and Core PHP Programming but I'm still missing something.
I have two functions in the same PHP file
BTW "$SEARCHDATE" is in this format YYYYMMDD such as 20020720 for July 20th, 2002
function set_search_info ($SEARCHDATE) { global $SEARCHYEAR ; global $SEARCHMONTH ; global $SEARCHDAY ; $SEARCHYEAR = substr("$SEARCHDATE", 0,4); $SEARCHMONTH = substr("$SEARCHDATE", -4,-2); $SEARCHDAY = substr("$SEARCHDATE", -2); }
function get_yesterday_info ($YESTERDAY) {
global $YESTERDAYHUMAN ; global $YESTERDAYLINK ; global $PREVIOUSCOMMENT ; global $LINKBACK ;
$YESTERDAYHUMAN = strftime("%B %d %Y",mktime(0,0,0,$SEARCHMONTH,$SEARCHDAY-1,$SEARCHYEAR));
$YESTERDAYLINK = "<< <a href=\"$SCRIPT?$YESTERDAY\">$YESTERDAYHUMAN</a>";
$PREVIOUSCOMMENT = Exec("/usr/bin/rdjpgcom images/$YESTERDAY.jpg");
$LINKBACK = "yes" ; }
But $YESTERDAYHUMAN keeps getting set to: November 29 1999 even though $SEARCHYEAR and $SEARCHMONTH and $SEARCHDAY are set properly outside of get_yesterday_info
