Hi All,
I am having trouble populating a pulldownbox with records from a table
in mySQL database.
I have a table with personnel records.
One of the fields is partner which holds a numeric value pointing to
the id of another record.
I am trying to get the value of the currently selected person's
partner.
for example:
id=1 name=John partner=2
id=2 name=Jane partner=1
With the code I use I do get the pulldownbox filled but it doesn't
display the name right partner info in the box.
$query="SELECT id, firstname, lastname, rank FROM myMembers WHERE id
<> $id ORDER BY lastname";
$result = mysql_query ($query);
echo "<select name=partner class=formFields id=partner
value=''>Partner</option>";
while($nt=mysql_fetch_array($result)){//Array or records stored in $nt
echo "<option value=$nt[id]>$nt[rank] $nt[firstname] $nt[lastname]</
option>";
/* Option values are added by looping through the array */
}
echo "<option value=$partner>$nt[rank] $nt[firstname] $nt[lastname]</
option>";
echo "</select>";// Closing of list box
?>
Can anyone help me here?
Regards
Marco

General observation, html attributes, such as the select name, option
values etc should be enclosed in quotes at the html level, such as one of
the following:
echo "<option value='$some_var_name'>some text</value>";
echo "<option value=\"$some_var_name\">some text</value>";
echo '<option value="$some_var_name">some text</value>';

Hmm
I thought:
echo "<option value='$partner'>{$nt['rank']} {$nt['firstname']}
{$nt['lastname']}</option>";
But I'm failing to find an appropriate page in the manual for a
definitive answer.

I don't think the formatting is the problem.
The problem is that the values are not set in the pulldownbox.
It does populate the box with the names but the value from the database
for the current record is not displayed.

Not to quibble about such a matter but you don't necessarily need
quotes around attributes (I prefer quotes as any syntax highlighting
editor will show the values up).
http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.2
In certain cases, authors may specify the value of an attribute
without any quotation marks. The attribute value may only contain
letters (a-z and A-Z), digits (0-9), hyphens (ASCII decimal 45),
periods (ASCII decimal 46), underscores (ASCII decimal 95), and colons
(ASCII decimal 58). We recommend using quotation marks even when it is
possible to eliminate them.

Yup, you're right - I was concentrating on the braces and forgot the quotes.
Mea culpa.

I believe that's why he said SHOULD, and not MUST.

Since constants are not evaluated within strings, the quotes on array
keys and curly braces are not needed.
(from http://www.php.net/manual/en/language.types.array.php )
// The following is okay, as it's inside a string. Constants are not
looked for
// within strings, so no E_NOTICE occurs here
print "Hello $arr[fruit]"; // Hello apple
The OP's original syntax is valid.
echo "<option value=$nt[id]>$nt[rank] $nt[firstname]
$nt[lastname]</option>";
The formatting of the "<option ..." line is not the problem.
I'd put print_r($nt) within the while loop and look at the query results.

sorry Jerry you lost me.
The form I am using this on is an profile edit page.
The user should get all his profile data and be able to change it and
save it.
That is why I need the value from the database along with the names
loaded in the listbox.

Chuck,
you are right. All the values get loaded in the listbox.
However the box itself stays empty. That shouldnt be.
There should be the name of the partner of the user in there.
Because it is represented by a numeric value, I think it gives a
problem.

When you View Source of the page what do you see where the lists are
supposed to be (there could be php error messages hiding there).

I always get tripped up by that one as it's common (for me) to output
the select tag followed by a php loop to create options. This puts the
error message within the select block and the browser does not display it.

Did you try my print_r suggestion - and look at the page source for it's
output - or error messages - hidden in the select block?

Marco, that comment wasn't directed at you.
Your first problem is - are you getting the correct data from the
database? If not, you need to do that first - which is a MySQL
question, not a PHP one (and should be asked in comp.databases.mysql).
If you are getting the correct information back from the database,
what's wrong with the partner name?

Chuck,

I do get the right data from the database.
The listbox gets filled correctly.
It is just that the name which is currently set as partner doesn't
show in the box.
I tried to fix that with:
echo "<option value='$partner'>{$nt['rank']} {$nt['firstname']}
{$nt['lastname']}</option>";
Problem is that I cannot do it at first I have to wait until the do
while loop for filling the listbox
has run.

Tony,
I changed my code and now it does load the names and give me the
current partner in the field.
<?php
$query="SELECT id, firstname, lastname, rank FROM myMembers WHERE id
<> $id ORDER BY lastname";
$result = mysql_query ($query);
echo "<select name=partner class=formFields id=partner
value=''>Partner</option>";
while($nt=mysql_fetch_array($result)){//Array or records stored in $nt
echo "<option id=$id selected>{$nt['rank']} {$nt['firstname']}
{$nt['lastname']}</option>";
//echo "<option value=$nt[id]>{$nt['rank']} {$nt['firstname']}
{$nt['lastname']} </option>";
/* Option values are added by looping through the array */
}
echo "<option value='$partner'>{$nt['rank']} {$nt['firstname']}
{$nt['lastname']}</option>";
echo "</select>";// Closing of list box
?>
Only problem is that I can't seem to update the field anymore.
Marco

This is none of my business, but in my experience writing long lines
of cryptic code is inherently bad. First off, if you get one
character wrong it doesn't work and then there you are. Secondly, the
next guy to pick up your code is going to have to decrypt it all.
Thirdly, if you use several lines of code it's easier to relate an
error message to the offending code, and if you should be so lucky as
to be using an interactive debugger it'll step through each line and
you can actually see what's going on. jmo.

Inset this in your while loop:
// Substitue your variable names
$f='';
if($rowAff['c_id']==$row['ch_id']) {$f="selected=\"selected\"";}
echo "<option $f
value=\"{$rowAff['c_id']}\">{$rowAff['church']}</option>\n";}
$f makes the current choice show in the option box. If I understood the
problem correctly.

The third one is not equivalent to the former two; the outer single quotes
prevent variable expansion. It would have to be
echo '<option value="' . $some_var_name . '">some text</value>';
Another possibility are HereDoc strings:
echo <<<HTML
<option value="{$some_var_name}">some text</value>
HTML;
Do not forget htmlspecialchars($some_var_name) in any case!

Mark the last sentence which is essentially what Denis said, and consider
that XML-based document types *require* the quotes (for well-formedness).
