Two things jump out.
1. TWEET_CREATEDAT is that suppose to be TWEET_CREATEDATE ??
2. two variables are accessed from the $row array, but the third is referenced from the $rowqry
array. This begs the question: Which is it? $row or $rowqry ?
Try this
$tweettable .= preg_replace(

I've encountered issue with checking $_POST['submit']
if(isset($_POST['submit'])) {}
If the form consists of checkbox/radio and text field, some of my forms can
be submitted by just press [ENTER] at the end of one of the text field. In
this case, the $_POST['submit'] is set even the submit button was not
clicked.
However, in some of my forms, $_POST['submit'] will not be set if I submit
the form by pressing [ENTER] in one of the text field.
So, if the later case
Re: [PHP] Re: Best way to test for form submission?
I've heard stories like this before, but never encountered it myself.
I forgot to mention that it is a good idea to give your submit buttons a
value attribute. Regardless of how the form is submitted, you should then
have a value for ['submit'].
Reminding the user that they must do anything other than the simplest things
is usually not a good approach. There will inevitably be users who do not
see/follow your reminder and use the enter button. Give the submit button a
value.

I don't know why or in what condition that pressing [ENTER] will not submit
the whole form include the $_POST['submit'].

You should encode the url before printing as usual way

Try putting all of that inside of a headers_sent(){} block. If nothing
is displayed, it means that you've already sent something to the
browser, so the headers have already been sent and the extra ones you
are sending do nothing. This sort of thing is shown in your error log
also.
If you still get the tif displayed as text, then are you sure that the
tif is valid?

RE: [PHP] Re: Best way to test for form submission?
To test a form I usually send the form contents to a php file that contains
the following;
foreach($_POST as $nm = $val) echo _POST[.$nm.] [.$val.]br;
foreach($_GET as $nm = $val) echo _GET[.$nm.] [.$val.]br;
Checkboxes and radio buttons only send their value if the control is
checked.
You can have multiple submit buttons (type=submit) on a form, but you
should assign them different name parameters to recognize which one is
clicked (any one of them will cause the form to be submitted, but the only
one that will establish a $_POST entry named submit is the submit control
that is named submit (name=submit).
Pressing enter is not sensed by most controls.
Most browsers will look at the field the cursor is positioned on when enter
is pressed, and if it is not one of the controls that response to an enter,
it scans the DOM (list of controls), and will apply the enter to the first
control that responds to an enter, most common is the type=submit control.
If a select control is between the text box and the submit button (in the
DOM list) the current entry for the select list will be selected and the
form will not be submitted unless the list includes a
onChange=this.form.submit(); javascript entry.
Be careful designing forms that are dependent on some of these behaviors,
like positioning a submit button to the right of a text box to intentionally
receive the enter, because different browsers will probably behave
differently.
Hope this helps a bit.

Just to throw it into the mix:
if(!empty($_POST)) for a general test of whether any form was posted.
There are more methods, I always use:
if($_SERVER[REQUEST_METHOD] == POST) {
do_something();

Balasubramanyam A knowledge.wea...@gmail.com wrote in message news:893c34ce0908270424n2d81596dq8529f13818dc9...@mail.gmail.com... Hello, I've written a simple application, where users need to login to access the features of the application. I want to develop login system such that, if user is already logged in, the application should not allow the users to login with the same login credentials. How do I accomplish this? Regards, Balu Personally, I have a table for sessions - each time a user logs in, their session is stored in the table, along with the session_id generated by session_start(), the userID, the time the session was last active, and an active flag. I use these fields to keep track of the users activity. If at any point the active flag is changed to inactive, the user's session is destroyed, and they are required to log in again. What you would do in your case, to only allow the user to be logged in at one location at any given time would be to automatically change the flag to 'inactive' on all the sessions in the table, associated with that users ID. Thus, if there is an active session elsewhere, when a new session is started, all other sessions associated with that ID will be kicked out. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] starting session with AJAX
Ok, so I've got an authentication/login form that is powered by ajax. The
user logs in, is authenticated, and the last step is to start a session and
save the necessary information in the $_SESSION vars.
For some reason, it appears (and almost of makes sense) that the session
that is started via the AJAX is lost once the ajax is complete.
AJAX calls the php, passing username and password
Php executes all the necessary authentication, etc etc
If, login is valid, it calls mySessionStart() (see below)
Checks to make sure the session has been started using isLoggedIn() (below),
which returns true
AJAX closes, receiving a successfully logged in message.
AJAX turns around and makes a second call, calling isLoggedIn() again, and
the session is gone
What I'm *guessing* is that because the PHP is not running on the active
page, but in the background the session is not being set for the active
page. Is there a way to pass the session back to the browser?

Debugging code has been removed for readability:
**
function mySessionStart($persist, $sessionID, $sessionKey, $debug=0){

// if persist, set cookie

function isLoggedIn($debug = 0){

RE: [PHP] user permissions
In this mechanism, does a role differ significantly from a group? I have to admin a CRM system that has both roles /and/ groups, and it always seems a bit excessive. But maybe there's some benefit to roles, as such, that I'm not seeing. Thanks, Ben [JP] As described, a role appears to act essentially the same as a group - a predefined set of permissions that can be assigned to multiple users (as opposed to a set of permissions unique to the user). Correct me if there's a better way, but I think individual permissions can be set similarly - except skip the role/group step and associate the binary permission string directly with the user. Thinking outloud: In your case where you're dealing with both individual permissions as well as groups, you could do both of the above, but have the individual permissions override the group. You'd have to figure out a third bit though, to act as a no change bit. Ie: 0 = deny, 1 = allow, 2 = NC. But, that wouldn't allow you to convert and store the bit string in decimal. So if group1 had a permission string of 1010, and user Joe was a member of group1, but you wanted to take away the first bit's permission, and grant the second bit, you could assign him the individual permission string of 0122 (deny, allow, NC, NC), resulting in his permissions being 0110. You'd check it by checking the individual permissions first, and if the bit (or digit in this case) were 2, then you would move on to checking the group permissions. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] What is the best way to process live data?
For those of you that remember (not likely but anyway) I am working on some code that splits CLF records and feeds them into a database. What I need to do now is automate it. So what I have is a program (urlsnarf) that redirects its output (simple cmd file.txt) to a file. The script currently processes this output line by line and does the SQL foo - i.e. script.php /the/file.txt Should I: 1) do away with redirecting the output from urlsnarf to a file and have the script run the process and have some kind of handle on it; foreach kinda thing? 2) keep outputting the info to a persistent file, reading any new appends and periodically cull this file. Seems like a waste of I/O if #1 is possible. 3) other options? Any help/push in the right direction is appreciated.
