Hi Shaun

thanks for your reply,
What i was after is a way of representing the data, given that you dont know
what columns will be displayed and how many rows etc?
/snip
One way to do it is to load the data into arrays. I generally use mysql_fetch_array()
to access recordsets. This delivers both an Indexed and associative array of values.
You can modify this behaviour with the last argument. Assuming you want to preserve
the keys (which will be the column headings in the sql result), in mysql_fetch_array()
you would use the constant MYSQL_ASSOC. You could do something like this:-
?php
// Assume you have a db connection
if (($result = mysql_query($sql_from_textarea))===0) {
// Drop out gracefully
}
// Check we have some rows
if (mysql_num_rows($result)) {
// We have some rows so load up an array with your recordset
// Start a counter
$counter=0;
// Step thru the recordset
while($data = mysql_fetch_array($result,MYSQL_ASSOC)) {
// loop through the current row, listing keys and values
while (list($k,$v)=each($data)) {
// create a new array member of the form
// $myarray[index][key]=value
$myarray[$counter][$k]=$v;
}
// increment the index counter
$counter++;
}
// Now we have an array which looks like the data so we can // display it
(you could do the keys bit up above as well
// actually)
// get the keys from the first element - safe cos we know
// we have at least one row
$keys = array_keys($myarray[0]);
// Now a standard loop through to first display the keys
// as headings then the data
$html = tabletr;
// Create a row of headings
for ($i=0;$icount($keys);$i++) {
$html .= tdb.$keys[$i]./b/td;
}
// Now loop through the rest of the data
while (list(,$v)=each($myarray)) {
$html .= tr;
// Send keys array pointer back to the start
reset($keys);
while(list(,$b)=each($keys)) {
$html.= td.$v[$b]./td;
}
$html .= /tr;
}
$html .= /table;
echo $html;
} else {
// Drop out gracefully
}
?
Does that all make sense ? Basically, you grab the recordset into an array whose
dimensions you can loop through. Then you grab the keys from an array element to give
you the columns. Then you loop through, using the keys as your guide for when to
change to a new row.
There may well be a more elegant way to do it but this would be where I would start !!
snip
I would only be looking to do 'selects' so how can i ensure that this is the
only type of query run?
/snip
Make sure the user you run the script as, only has select permissions on the db you
are using.
Once again, hope this helps ;-)

I would be very interested to see an example of how it would be possible to enter a query into a text area and the results of the query displayed on the next page, similar to PHP admin I guess, are they any examples out there? Issue the query with mysql_query() and check for an error. If there's an error, display mysql_error() or do your own error handling. From there, you'll count the number of fields returned by mysql_num_fields(). Loop through with mysql_field_name() to create your header row. The header text will match whatever the name of the column was. Then loop through mysql_fetch_row() to get all of the rows returned from the query. You already know how many fields there are, so just loop through the result of mysql_fetch_row() that many times and put each element in it's own td tag. That's pretty much it. ---John W. Holmes...

Hi,
I am trying to get PHP mail() to do the following:
1) Grab email addresses from a database and put in the
BCC of the email. (hidding their email address)
2) Grab first names from a database and put in the
body of the email.
Below is a script I am using, does not do any queries
to any database because I am not sure how to do it in
the function. I have tried but have failed so thought
I'd ask here. Can anyone help? Here is the code I am
using...
?php
$myname = Me Myself;
$myemail = [EMAIL PROTECTED];
$contactname = Mister Contact;
$contactemail = [EMAIL PROTECTED];
$message = hello from .$contactname.;
$subject = A email;

$headers .= X-MSMail-Priority: High\r\n;
$headers .= X-Mailer: Just My Server;
mail($contactemail, $subject, $message, $headers);

Maybe I need a different function? If so could someone

Rather than using isset() you may need to use
session_is_registered(). This is specifically for checking the
existence of a session variable. I would do something like
?php
// need this on all pages where you want to work with // the session
var
session_start();
// Check for the existence of the session var and create
// it if it doesn't exist
if (!session_is_registered(ses_username)) {
session_register(ses_username);
}
// Are we getting a form var thru ? if so pop it into the session var
if (isset($frm_username)) {
$ses_username = $frm_username;
}
// then in your scripts you can do
do_my_amazing_function($ses_username);
?
As long as you have session_start() at the beginning of each script,
$ses_username is now available across scripts.
snip
$value=$_HTTP_SESSION_VARS['your_variable_name']; //get the value
}else{
$_HTTP_SESSION_VARS['your_variable_name']=new value;
}
/snip
Hope that helps.

Re: [PHP-DB] dynamic forms

It depends on which one I choose from the drop down menu, that clicking submit it displays the right table.. now, I need to have a form on the page that would let me insert new records. Of course I don't want to make a form for each table, so I would like to change the entries and values of the insert form in relation to the table I choose from the drop down form above mentioned. Of course the id and created are NULL because they should get filled automatically. thanks for your help. mas Mas, We recently did something very similar to this for a client. One approach that you could take is to parse the results from describe table_name (that statement is for Mysql but similar things can usually be done for other database engines) for the table selected in the List control. This really is fairly straight forward. You have isolated the table name that you are interested in... Great Execute a database query to get the field description for the table. Decide what action you wish to take for each field. For example, radio buttons for an enum field, hidden for a primary key and created by.

[PHP-DB] PHP mail fetching email address(es) from database question!
Hi,
Fristly, thanks Jen for your information earlier. I
have managed to fetch email addresses from a database
to be sent out via email fine. But I have a few
problems which are listed below.
1) I can't get from to work at all. :( When the
emails are generated it goes out as nobody @ domain.
I have tried putting $HEADERS .= email but it fails
badly. Any idea why? (the emails go out fine with
the message to all people in the database)
2) I have not managed to find out how to put their
first name at the top of the message. e.g. to bob,
... I have thought of a few ways, have not tried it
yet. But would be in the mysql function before it
closes and could be legnthy.. I'd prefer to have it
like a single line and further down have the message.
At the pressent time I type a message in a form from
the browser with the subject. Even if I had from on
that form also to input is fine but I can't get it to
work. :(
The code is below. Quite easily achieved in the end.
All help is mostly appreicated.
Thanks in advance.
Jerry
