hallo,
this was working well , submit is evaluating true, no errors, but
now data is not shown in databse table
?php
if($submit)
{
$dbh=mysql_connect (localhost, root) or die ('I cannot connect to
the database because: ' . mysql_error());
mysql_select_db (dollar1_allinfo);
mysql_query(INSERT INTO totalinfo (Username,Password) VALUES
('$loginusername','$loginpassword'));
}
?
what may be glitch

I suspect that your $submit is not set up, try the following echo
statements before the if statement:
echo --$submit--;
echo --$_POST[submit]--;

hallo ,
i have wriiten simple php script , below.
created databse dollar1_allinfo with table 'totalinfo'
but on clicking submit button ,

Re: [PHP-DB] query is not executing data is not entering in created database
hallo,
see below code. query is not executing and data is not shown in table of
database.after submit button hit.
how to evaluate $submit true. have Tried these statements before if statement
echo --$submit--;
echo --$_POST[submit]--;
echoSubmit = $submit ;
but still query is not executing.
?php
if($submit)
{
$dbh=mysql_connect (localhost, root) or die ('I cannot connect to
the database because: ' . mysql_error());
mysql_select_db (dollar1_allinfo);
mysql_query(INSERT INTO totalinfo (Username,Password) VALUES
('$loginusername','$loginpassword'))or die (mysql_error());
}
?
suggest changes in above code to execute query.
thank you.

The reason people told you to put the above code is for troubleshooting.
It's not going to fix your query. What do you actually see resulting
from the above code before and after you hit your submit button? My
crystal ball says you see this:
Submit =
Am I right?
?php
if($submit)
{
$dbh=mysql_connect (localhost, root) or die ('I cannot connect to
the database because: ' . mysql_error());
mysql_select_db (dollar1_allinfo);
mysql_query(INSERT INTO totalinfo (Username,Password) VALUES
('$loginusername','$loginpassword'))or die (mysql_error());
So if you see what I guessed above, then $submit is not set, so whatever
code you have here not going to execute. Do you know how an IF
conditional works? Do you know that if it evaluates to FALSE, then
nothing within the conditional block is executed? Your query is probably
fine, but the code is just never getting to it.
I could tell you to use $_GET['submit'] or $_REQUEST['submit'], but
would you know why or where to use it?

[PHP-DB] Undefined indicies
Slightly off topic, I apologise.
Total newbie. In many php DB tutorials I've seen, it's recommended to set
register_globals off, and error reporting to E_ALL.
When I looked at my system, register_globals was enabled and error reporting
was set to E_FATAL. I changed them to the suggested values (off and E_ALL),
and all hell broke loose. Clearly, I must not be very good at PHP yet. ;)
First question:
register_globals is a matter of security, so that's definitely valuable to
turn off. Is setting error reporting really useful if my aim is to become a
better PHP programmer?
I'm thinking along the lines of lint/splint, where this line of code in C:
printf(hello world\n);
generates a useless warning because I'm not using printf()'s return value.
I'm wondering whether it's useful for a scripting language, like PHP, to
warn me when I use code like:
if ( $_REQUEST['action'] == 'foo' )
do_something;
when I don't access the URL with a ?action=foobar type request.
Should I change error reporting back to E_FATAL or is being this
compulsive about warnings good for me (and my security)?
Second question:
If being compulsive is good for me, what's the best way of handling
something like above? From browsing php.net, I've thought of a few ways,
like a controlled suspension of compulsion:
if ( @ $_REQUEST['action'] == 'foo' )
do_something;
or, lord forbid:
if ( isset($_REQUEST['action']) $_REQUEST['action'] == 'foo' )
do_something;
and also variations on a theme:
if ( array_key_exists('action', $_REQUEST )
$action = $_REQUEST['action'];
if ( isset($action) )
do_something;
Personal preference must play into this, but I'm wondering what more
experienced PHP programmers do. My code is riddled with this kind of thing.
Thanks (and sorry for the long winded / slightly off-topic post!)
Pete

In many php DB tutorials I've seen, it's recommended to set register_globals off, and error reporting to E_ALL. Good recommendations. Setting the error reporting to E_ALL is for when you are developing your application. You'd want to turn off error reporting (and log them to a file, for example) when it goes live. When I looked at my system, register_globals was enabled and error reporting was set to E_FATAL. I changed them to the suggested values (off and E_ALL), and all hell broke loose. Clearly, I must not be very good at PHP yet. ;) First question: register_globals is a matter of security, so that's definitely valuable to turn off. In your case, being a new programmer, yeah it's better to have it off. Note that having register globals ON makes it easier for you to introduce security issues into your code, especially if you're new. You can program security with it ON or OFF, it just takes some experience. Is setting error reporting really useful if my aim is to become a better PHP programmer? It is in my opinion. It'll help you during development to debug your code. I'm wondering whether it's useful for a scripting language, like PHP, to warn me when I use code like: if ( $_REQUEST['action'] == 'foo' ) do_something; when I don't access the URL with a ?action=foobar type request. In that specific example it may not be helping a lot. That's because you know what's going on, though and you know why the value isn't defined. What if you're doing something like if($something) though. You're 100% sure $something is set to a known value so if it really wasn't (for whatever reason), without error reporting telling you it's undefined, you'd probably waste time troubleshooting something else. Just one example, but either way it's going to help. If being compulsive is good for me, what's the best way of handling something like above? From browsing php.net, I've thought of a few ways, like a controlled suspension of compulsion: if ( @ $_REQUEST['action'] == 'foo' ) do_something; or, lord forbid: if ( isset($_REQUEST['action']) $_REQUEST['action'] == 'foo' ) do_something; Why lord forbid? This is how you should do it. I mean, since you do know what the issue is here, you could use the first method if you're afraid of isset() or something. I do it the second way, but yeah, it's personal preference. -- ---John Holmes...

[PHP-DB] auto_increment
I have the auto_increment on one of my variables. During the past few days I have been doing testing on a live database and created several test records which I now have deleted from my table. Is there any way of setting the auto_increment value to match the last correct number? Ron -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ron You don't say what database application you're using, but if it's MySQL, you can change the auto increment value using: ALTER TABLE tablename AUTO_INCREMENT = 1 That being said, you actually don't have to do this (and often shouldn't, really). Having gaps in your auto increment sequence shouldn't be a problem. Larry -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
