my db has multiple tables with an online form that captures data to go into one or more of these tables.

i have total success with a single table db - from user entered data to mysql db record - perfecct.

now i am testing the new multi-table db using just two of the tables, and i know the variables are set correctly because i use an 'echo' statement to print them on a confirmation page.

yet, there are no records in the db.

i've got the varibles written first as:

$fieldname1 = $_POST['fieldname1'];

then, I do the;

if (isset($_POST['submit'])) {
mysql_connect("mysql.ips.com","dbuser","dbpassword");
mysql_select_db("dbname");

then, i've got the insert query written in this sequence:

$query="insert into tablename1 (field1, field2, field3)";
$query.="VALUES ('$field1','$field2','$field3');
$query="insert into tablename2 (field4, field5, field6)";
$query.="VALUES ('$field4','$field5','$field6')";

---------------------

-----------------
note that the db has been set up with all the necessary tables (12) but i am testing it in steps.

The previously mentioned 'successful' test was with a test db that had only one table.

So I think there is some clever little mysql something that has to play here, and hoping there is a clever somebody here that can steer me in the right direction!

Many thanks!

yamy

I guess we can assume that your code looks like this
Code: 
...
$query="insert into tablename1 (field1, field2, field3)";
$query.="VALUES ('$field1','$field2','$field3');

[COLOR=red]mysql_query( $query );[/color]
...
$query="insert into tablename2 (field4, field5, field6)";
$query.="VALUES ('$field4','$field5','$field6')";

[COLOR=red]mysql_query( $query );[/color]
...

well, no, it does NOT look like that!

your red-letter insertions are what i don't have.
are they to separate the insert calls?

are the ... required also, or just shorthand for 'more like this'?

thanks

The
Code: 
mysql_query($query);
statement actually sends the query to the database. Without that, $query is just a php variable with some value that happens to look like an SQL query.

My elipses ( ... ) mean whatever other code you have in your script, etc.

Take a look at the PHP Manual to learn how to use MySQL with PHP.

This particular PHP function is at

From there you should be able to follow links to the whole set of functions used with MySQL.

The function I posted executes the query. Which is essential of course. It seems like the one-table script would have needed a call to this function also. Did your one-table scritp work without that?

Hi Rac2,
ok i think you might have nailed the problem on the head.
my working model uses:

$result=mysql_query($query)
followed by
if ($result) echo "some stuff";
else "echo some other stuff";

so, to follow your point, it seems I need to have my if ($result).... OR, your $mysql_query

and I think that each INSERT INTO table1 command must resolve before INSERT INTO table2.

do you agree?

thanks

Probably. Just remember, computers do one thing at a time in the order in which you give them programmed intstructions. They neither know nor care what you intend to do.

So yes take of business on table 1. Then move on to table 2.

I can get an entry into the first table.(company)

i managed to get one entry into the second table (contact), one time - and then it stopped working when i itried to add a second field in the second table,

must be another of those dreaded 'typos'.

a well, this code does not print the echo statements following the closing else }

all help welcomed.

}
mysql_query($query);

$firstName = $_POST['firstName'];

if (isset($_POST['firstName'])) {
require("./en/includes/mysql_connect_pb.php");
$query="insert into contact (firstName)";
$query.=" VALUES('$firstName')";

mysql_query($query);
} else {

echo "here is what you sent to the database -<br />company Name - $CompanyName; first name - $firstName; last name - $lastName";
}

require("./en/includes/mysql_connect_pb.php");
$query="insert into company (companyName)";
$query.=" VALUES('$companyName')";


$result=mysql_query($query);
if ($result) echo "added one record successfully.";
else echo "error";
}
?>
<?php

$firstName = $_POST['firstName'];

if (isset($_POST['firstName'])) {
require("./en/includes/mysql_connect_pb.php");
$query="insert into contact (firstName)";

:) this is realy the wrong place, you better switch to php forum

but to your problem
a) you may be getting error when requiring the same include file twice while output of error messages is supressed and you do not know the reason of not inserting data into db - use it in one general place (at the begining of doc?) or use require_once() function
b) you could better debug your code while using the get method first
c) for debuging purposes you can add an else part to the if(s) where you are checking for input variable(s)

...

<joke>z) get some php book</joke>
