$Proj1 now contains a comma-separated list of the values passed to
$s_Industry, which was filled by the CCGetParam() above. The above code
block is equivalent to (and would be better coded as):
if (count($s_Industry) 0 AND is_array($s_Industry)) {
$Proj1 = '.implode(',', $s_Industry).';
}
which may look somewhat familiar to you!
//Parsing next array
if (count($s_LocationState) 0 AND
is_array($s_LocationState))
{
foreach ($s_LocationState as $key = $value) {
if ($Proj2 != ) $Proj2 = $Proj2.,;
$Proj2 = $Proj2.'.$value.';
}
}
//Parsing file array
if (count($s_TaxTerm) 0 AND is_array($s_TaxTerm)) {
foreach ($s_TaxTerm as $key = $value) {
if ($Proj3 != ) $Proj3 = $Proj3.,;
$Proj3 = $Proj3.'.$value.';
}
}
These two blocks are similar for the other two parameters, $s_LocationState
and $s_TaxTerm
Here is what will be the death of me :)
First the where condition below is being appended to
anoher file in my main sql statement (don't ask:))
CC keeps their code in various sections and files.
Anyway , if you remember yesterday, it was determined
that I needed the where condition to be dynamically
created based on the user input.
Obviously the code below does nothing of that sort.
Obviously it does, using the lists of values built above.
So as a start, I'm trying to figure out what I can do
with this section here (since this is really what
needs to be changed, I think) to make it all right.
if ($Proj1)
$VendorJobs-ds-SQL.= AND (`VendorJobs`.Industry IN (.$Proj1.));
Plug the value for $Proj1 built above into this, and again you have
something that may look very familiar to you. It's the very same IN clause
I was urging you to use yesterday! ;)
if ($Proj2)
$VendorJobs-ds-SQL.= AND
(`VendorJobs`.LocationState IN (.$Proj2.));
if ($Proj3)
$VendorJobs-ds-SQL.= AND (VendorJobs.TaxTerm IN (.$Proj3.));
echo SQL:. $VendorJobs-ds-SQL.br;
So you now have a dynamically built portion of SQL, in $VendorJobs-ds-SQL,
that has a clause like AND x IN ('a','b','c') for each input field that
has any values set. According to your specs, this could be anywhere up to
six separate clauses. This seems to be exactly what you wanted, so your
code looks good to go.
To help you understand exactly what's going on here, or in any script or
program you're struggling to interpret, I would recommend two time-honoured
techniques:
(i) Dry running: get out your genuine old-fashioned pen and paper, pretend
you're the PHP interpreter processing this program, and write down the value
of each variable as you work through the code. Yes, it can be quite
long-winded and tedious, but you really get a tremendous feel for exactly
what's going on. The number of times I've done this and cursed myself as
I've watched a value going out of range, or not getting set at all, I
couldn't begin to count.
(ii) As a variation of the above, put *lots* of debugging echos in your
script: echo the value of every variable frequently and redundantly -- it
can help sometimes just to have the reassurance that a value really hasn't
changed, even though you know it absolutely shouldn't!! Again, if you're
struggling with how a script operates this can help you see how values are
built up, and can often show you exactly where a wrong value gets calculated
(and how, and maybe even why). It's especially important to echo your final
complete SQL statement just before it's executed, so that if it produces an
error message you've got the actual relevant SQL right in front of you.
Hope this helps.
Cheers!

Just to confirm,
This is what I'm going to start with:
Yeah, I'd say you've pretty much got it, except...
//base sql statement
$sql = select * from jobs where record_deleted = 'NO' ;
if (isset($_POST['states'])){
Your SQL is going to need some sort of conjunction here, as your WHERE phrase already
has an initial condition in it. I'm guessing you'll want an AND, so:
$sql .= 'AND ';
//check to see if the states is an array
// multiple items or just one
if (is_array($_POST['state']))
You've switched from $_POST['states'] to $_POST['state'] -- fix whichever is wrong ;)
$sql .= state='.implode(' OR state=',
$_POST['state']).';
Given the conditions you want your WHERE phrase to test, you're going to need more
parentheses to force the ORs to be evaluated before the ANDs; this is where the IN
syntax, IMO, is more readable. So you want either:
$sql .= (state='.implode(' OR state=',$_POST['state']).');
or:
$sql .= state IN ('.implode(',',$_POST['state']).');
}else{
//$_POST['state'] is not an array
$sql .= state = '.$_POST['state'].' ;
}//end if
if (isset($_POST['job'])){
if (isset($_POST['state'])){ $sql .= AND ; }
And throughout this second block you've used a cut'n'paste of the first block without
altering ['state'] to ['job'] -- just the sort of oversight that can give you the
raving heebie-jeebies somewhere down the line if you fail to fix it! ;)
//add in the AND if the state is set
//check to see if the states is an array
//multiple items or just one
if (is_array($_POST['state']))
$sql .= state='.implode(' OR state=',
$_POST['state']).';
$sql .= );
}else{
$_POST['job'] is not an array
$sql .= job = '.$_POST['job'].' ;
}
//end if
Given the moderate complexity of this code, I'd strongly recommend echo-ing out $sql
immediately before it's used whilst you're in testing mode. When your query fails,
you'll already be one step ahead in working out what the problem is.
Cheers!

Re: [PHP-DB] MultSelect ListBox hell!
Well don't hate me for coming back here. I am shamed
and embarassed enough.
And while I appreciate all the great code and feedback
received , I've run into a glitch.
(oi) Because I'm using CodeCharge, it's not easy to
just insert custom code anywhere. That is one of
those code generators. I suppose if I had more hands
on php coding the way could be found.
So here is what I have:
//Here is defines the field variable and uses
//CodeCharge function to grab the variable
$s_Industry = CCGetParam(s_Industry, );
$s_LocationState = CCGetParam(s_LocationState, );
$s_TaxTerm = CCGetParam(s_TaxTerm, );
//Here is the parsing of the array. I'm not sure
what the $proj variable is for. I gather it's a
holder for the array values
if (count($s_Industry) 0 AND is_array($s_Industry))
{
foreach ($s_Industry as $key = $value) {
if ($Proj1 != ) $Proj1 = $Proj1.,;
$Proj1 = $Proj1.'.$value.';
}
}
//Parsing next array
if (count($s_LocationState) 0 AND
is_array($s_LocationState))
{
foreach ($s_LocationState as $key = $value) {
if ($Proj2 != ) $Proj2 = $Proj2.,;
$Proj2 = $Proj2.'.$value.';
}
}
//Parsing file array
if (count($s_TaxTerm) 0 AND is_array($s_TaxTerm))
{
foreach ($s_TaxTerm as $key = $value) {
if ($Proj3 != ) $Proj3 = $Proj3.,;
$Proj3 = $Proj3.'.$value.';
}
}
Here is what will be the death of me :)

if ($Proj3)
$VendorJobs-ds-SQL.= AND (VendorJobs.TaxTerm IN
(.$Proj3.));
echo SQL:. $VendorJobs-ds-SQL.br;
As a crash course on this issue, search form has 6
fields, user may enter 1 or up to all 6 values, but
the results should be refined as more values are
added. In other words AND is correct conditional ,
but has to allow for user to choose how many values
they want to put in.
Anyway , don't throw me off the list yet! I am reading
on PHP, but I have gone pretty far on this project and
prefer to finish it without diverting back/

You need LocationState to be, in your example, Alabama OR California. Also, I would write that
SQL phrase LocationState = 'Alabama' OR LocationState='California' .

Correct, I've added that AND, and so now it will
match
jobs by state.
But without choosing state, no job return.
So I'm figuring i'll have to add another series of
OR's . Trying to figure that out now.

I am in the process of building a search form
for
the
database. The entire thing consists of 3 multi
selects and 2 text boxes with a contains. Oh
and
I've only rigged 2 of the multi selects for the
time
being.
So the way the multiselects should work that
the
user
can choose one or the other or both, but the
more
criteria provided back to the query , the more
refined
the return.
Here is the code and my tale of woe
follows:($projects
is a just a holder / variable)
function BindEvents()
{
global $VendorJobs;
$VendorJobs-ds-CCSEvents[BeforeExecuteSelect]
= VendorJobs_ds_BeforeExecuteSelect;
}
//End BindEvents Method
//VendorJobs_ds_BeforeExecuteSelect @2-A4F75E44
function VendorJobs_ds_BeforeExecuteSelect()
{
$VendorJobs_ds_BeforeExecuteSelect = true;
//End VendorJobs_ds_BeforeExecuteSelect
global $VendorJobs;
$s_Industry = CCGetParam(s_Industry, );
if (count($s_Industry) 0 AND
is_array($s_Industry))
{
foreach ($s_Industry as $key = $value) {
if ($Projects != ) $Projects = $Projects.,;
$Projects = $Projects.'.$value.';
}
}
if ($Projects)
$VendorJobs-ds-SQL.= AND
(`VendorJobs`.Industry
IN
(.$Projects.));
$s_LocationState =
CCGetParam(s_LocationState,
);
if (count($s_LocationState) 0 AND
is_array($s_LocationState)) {
foreach ($s_LocationState as $key = $value) {
if ($Projects != ) $Projects = $Projects.,;
$Projects = $Projects.'.$value.';
}
}
if ($Projects)
$VendorJobs-ds-SQL.= AND
(`VendorJobs`.LocationState IN
(.$Projects.));
echo SQL:. $VendorJobs-ds-SQL.br;
return $VendorJobs_ds_BeforeExecuteSelect;
If you notice in the the SQL the AND, I've
changed
them back and forth to OR and a combo of AND in
the
first and OR in the second.
If I have OR in both, then each multi works on
it's
own, no refined / results. If I have AND in
both,
then they come together but if I try to add
more
values (like a multi select should allow) I get
a
no
records return.
So something like this using in both AND:
I choose from Industry : Accounting and Finance
From LocationState: I choose Alabama
great it gives back to me all accounting and
finance
records Alabama
But if I add in LocationState, Alabama and
California
then a no records is returned.
Anyway, if anyone has some pointers or ideas
I'd
greatly appreciate.

RE: [PHP-DB] MultSelect ListBox hell!
Bastien,
Sorry , I hit the send button to fast on the last
response. Is the second series of statements for the
jobs field ? It looks like it is but you copied and
pasted I think from the first set (states) ...or maybe
Im wrong, the whole thing , needs to be created for
each element.

This check isn't really necessary in PHP, since $_POST['state'] will *always* be an

PHP has the very nice implode function to make this much easier:

This check isn't really necessary in PHP, since $_POST['state']
will *always* be an array if the form field has NAME='state[]',
even if only 1 is selected.
But remember that the form comes from the client. Just because you create
the form with state[], that doesn't mean I'm going to send it that way. ;)
If it was changed, it could cause an error that might expose file structure
or whatever. So the check is a good thing to ensure nothing was changed.

Yeah, true -- I have a very bad tendency to forget about security considerations like
that until someone reminds me (often a posting on this list does it ;). Just because
I have a well-defined set of well-behaved users...!!

Everything inside the if(is_array()). Ummm, that should probably still be a

version, so:
if (is_array($_POST['state']))
$sql .= state='.implode(' OR state=', $_POST['state']).';

Just to confirm,
This is what I'm going to start with:
//base sql statement
$sql = select * from jobs where record_deleted = 'NO'
;
if (isset($_POST['states'])){
//check to see if the states is an array
// multiple items or just one
if (is_array($_POST['state']))
$sql .= state='.implode(' OR state=',

}else{
//$_POST['state'] is not an array

$sql .= );
}else{
