[PHP-DB] Erratic isset()
Hi Can anyone shed some light on this problem? The DB update only happens when I change the if(isset($submit)) to read if(!isset($submit)). Yes, I am using PHP 4.0.6 but have also tried with PHP 4.2.2, same problem. Code snippet: //HTML body ?php if(isset($Sumbit)): /* Connecting, selecting database */ $link = mysql_connect(192.168.0.100, sff_user, sff98) or die(Could not connect); print Connected successfully.br; mysql_select_db(sff) or die(Could not select database); $doit1 = INSERT INTO members VALUES(NULL,'$first_name','$last_name','$addr1', '$addr2','$postnummer','$postort','$land','$tel','$mob','$email','$memb_date ','$comments'); mysql_query($doit1); //put the data in members table printf (bDatabase updated./b Enter a new member?); /* Closing connection */ mysql_close($link); endif; ? //print HTML form etc...

[PHP-DB] transactions and persitent connections
I'm a little confused/worried about database transactions, persistent connections and PHP. I am worried that if I use persistent connections it might be possible for more than one PHP script to be inside the same transaction at the same time. For example: 1- page1.php is a script that opens a persistent connection to a DB and starts a transaction. 2- User 1 goes to page1.php 3- User 2 goes to page1.php My questions: 1- is it possible that user 2 will be using the same connection as user 1? So if user 1's transaction fails so will user 2's? 2- If user 1's hits the stop button on his browser, what happens to his transaction? I assume it is stopped. But what about the connection? If user 2 gets the same connection, will his transaction fail? Thanks, Jc -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] How to pass multiple checkbox values thru form??
I'm working on the same problem but I need to read the code, not write
it:, here are a few links and my code if you might help me in return:
http://www.experts-exchange.com/Web/Web_Languages/PHP/Q_20117420.html
my code:
mysql_db(); # connects to mysql
for($i = 0; $i sizeof($check); $i++) {
# echo $i;
# echo 'p';
# $data = $check[$i];
$sql = (SELECT * FROM kodak_user_pictures WHERE ID = '$check[$i]');
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
# $row = mysql_fetch_array($db_data);
$db_ID = $row[ID];
$db_picture_name = $row[picture_name];
echo $db_ID;
echo 'p';
echo $db_picture_name;
echo 'p';
echo $ID;
echo 'p';
echo $picture_name;
echo 'p';
echo $result;
}
so many echoes because I'm trying to figure out what works and what
doesn't.

Subject: [PHP-DB] How to pass multiple checkbox values thru form??
hii
i have one form in which i print records from mysql database. while
displyaing those records i display one checkbox with each record. i want
the
user should select the checkbox corresponding to the record which s/he
wants
to delete.
i display those records after running one query. hence each time no.of
records are diff. so its difficult to hard code names for check boxes.
for
name attribute in input type=checkbox tag, i define one array. having
same
name as the key field in the table. and value for which is also set
dynamically.
FORM NAME = act_qmd_subj_frm METHOD = POST ACTION =
confirm_delete.php
while ($row = mysql_fetch_array($result))
{
..
echo tr;
//call function to display the contents of $row in table
print_entry($row,subj_id,subj_name,subj_desc);
print td valign=top align=centerinput type=checkbox
name=\subj_id[]\ value=\.$row[subj_id].\ Yes, delete entry
#.$row[subj_id]./td\n;
...
}
INPUT TYPE=submit NAME=del_but VALUE=Delete nbsp nbsp
INPUT TYPE=submit NAME=modify_but VALUE=Modify nbsp nbsp
INPUT TYPE=reset NAME=clear_but VALUE=Clear nbsp nbsp
/FORM
when i submit the form to confirm_delete.php i run one code there to
print
the array subj_id[] which is supposed to contain values of the
checkboxes
which are selected to delete or to modify. but the array subj_id[]
contains
no value at all. echo count($subj_id) gives 0.
is there any other way to pass multiple checkbox values from the form???
i got the above trick from the book MySQL/PHP Database Applications
(By,
Jay Grrenspan and Brad Bulger) in one script they have passed checkbox
value
thru array by this way, and its working fine.
can anyone PLS figure out what wrong im doing???
thnx and regds,
smita.

[PHP-DB] ereg_replace
Could somebody explain to me how the ereg_replace function works? For as for as I understand it replaces strings by a different string (as explained on the php site) but what I don't understand is how the following line creates real links: $Content = ereg_replace([[:alpha:]]+://[^[:space:]]+[[:alnum:]/], a href=\\\0\ target=\_blank\\\0/a, $Content); How does this work? Where is the alpha, space, alnum and \\0 stuff come from? The main reason why I ask this is because I want to search in a string for strings like [QUOTE] and/or [/QUOTE] and replace these with html tags but for some reason it starts doing realy weird stuff :-) Cheers Prodoc -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If user 2 No, the script won't have any idea the stop button has been pressed. It should have executed and completed its transaction regardless of what the user does. Perhaps you are thinking that user 1 visits the page and begins a transaction, and then visits it again to complete the transaction? That doesn't work. You have no guarantee that user 1 will get the same connection both times. (That is, don't try to spread a transaction out over multiple visits by a user.) gets the same connection, will his transaction fail?

[PHP-DB] RE: [PHP] RE: [PHP-DB] RE: [PHP] why do i get this error please tell me?
Then check the MySQL manual using the URL I posted! PHP doesn't care about the hundred or so reserved MySQL words. MySQL does. Perhaps you're confusing the two. Please check what I said: PHP != MySQL The documentation for each is separate. PHP has convenience functions for talking to a MySQL database. It does not parse or check your SQL statements for correctness - it just passes them along and lets the MySQL library do its work. PHP does this for a great number of products: cURL, GD functions, various ODBC interfaces, etc. It's up to you to read the support docs for those products to use them fully. The docs for PHP don't need to be cluttered with deep and detailed explanations of every supported interface, not would I expect them to. -Original Message- From: victor [mailto:[EMAIL PROTECTED]] I meant besides the UPDATE or SELECT or any filed that those words might interfere with... - Victor www.argilent.com -Original Message- From: Mark Charette [mailto:[EMAIL PROTECTED]] hem.

My problem is in displaying this text field. The text that will be entered will be formatted, e.g. 1. Step 1 2. Step 2 3.

That does mean it's possible for a transaction to be started by one script and then either committed or rolled back by the next if they share a connection. That's exactly what I meant and feared.

If user 2 No, the script won't have any idea the stop button has been pressed. It should have executed and completed its transaction regardless of what the user does. Really? I don't exactly know how PHP script execute but I though that is that the user goes to a page that starts a script and then closes the browser that causes the script to end prematurely. Am I wrong? Does the script go from start to finish even though the connection to the browser has been severed. I.e. The script will run complete even if there is output to the browser as the script is running? If the script goes from start to finish regardless of what the user does that would be nice. That way I am sure a transaction will go from start to finish, and if I make sure to either commit or rollback the transaction at the end of the script then I don't have to worry. Maybe the safest thing to do is not use persistent connections at all? Or in your opinion is there a safe way to use persistent connections and transactions?
