When I enter names and click on one of the search buttons, I don't get sane results.

PJ: Okay, if you enter Johnson in the last name text box and click the Search Last Name button, the demo will provide you with a record that has Johnson as the last name. Likewise, if you enter John in the first name text-box and click the Search First Name button, the demo will provide you with a record that has John as the first name. Both of those work -- so, where's the confusion? Apparently you want to enter Johnson in the last name text box and John in the first name text box and then click something to find that specific name right? Well, the demo is not set-up that way -- there is no Click here and I'll find the specific person who has this first and last name. The demo is set up to search for first OR last name OR email address. It also provides a way to sort the records such that one can sequentially step any sort made on first-name/last-name; or last-name/first-name; or email address. It only does what it says it does. Did you review the instructions at the bottom? Cheers, tedd Tedd, nice looking contact demo thingy.. but PJ has a point. ;-) It would make the app perhaps more intuitive if one could just type text in any of the 3 fields and then spit out results that match all of the comparisons that are not blank by clicking one button. .. not to take away from what you have done, but perhaps a future evolution of the demo. Donovan Exactly. I expected to get all instances of Johnson or of John but I got only 1 and I saw that there were others, so that didn't seem right. And, if I may point out, the instructions are not available if js is not enabled O:-) so that leaves only intuition to decipher things especially if you only want to do a search. BTW - I seem to have solved the problem of filtering the inputs. Was rather simple: just use one form for each search. And to avoid using @ for the error of $_POST['select'] one just has to declare one just has to declare $_POST['submit'] = ; at top of script. :-) (I'm learning, I'm learning) - now I have to check it all out. -- unheralded genius: A clean desk is the sign of a dull mind. - Phil Jourdan --- p...@ptahhotep.com http://www.ptahhotep.com http://www.chiccantine.com/andypantry.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Anyway, I have my setup working using $_POST which gives me an array of the inputs plus the submit string all in a one-dimensional array. Great. Now I'm playing with how to set things up to eliminate extraneous inputs which will be made, will, will not. So, filtering becomes rather important and complicated. I thought switch would work, but it doesn't look promising. I can clear the 'submit' string by declaring $_POST['submit'] = ; at top of page; which seems strange?? But I can't figure out how to eliminate or avoid extraneous inputs. In other words, If I have input in the Search Title field and input in any one or all of the other search options, clicking on Search Title the returned array includes all options I'm not sure how to filter that. :-\ Is there some way to set the other inputs to null when choosing the search?

Re: [PHP] checkboxes
Excellent response. You should always be expecting certain data. So if no checkboxes are checked, your code should realize that since it was expecting the data and none was submitted. The lazy way is much easier to code, but it is actually fairly efficient. You are only hitting the database twice, once of the delete and once for the bulk insert. On a fixed record length table, the lazy way may actually be quicker.

[PHP] checkboxes
I have a form where I am dynamically building a bunch of checkbox
inputs. Then when submitted, I need to update the db. Problem is, of
course, if the checkbox is unchecked then the $_POST doesn't have the
value in the array. How can I get the value from $_POST even though
it's unchecked?
For example, here would be the generated form:
input type=checkbox name=cars[2] value=1Car 1
input type=checkbox name=cars[3] value=1Car 2
input type=checkbox name=cars[4] value=1Car 3
input type=checkbox name=cars[5] value=1Car 4
Then in the update I loop through:
foreach($_POST[cars] as $id=$value){
//update vehicles set value to yes or no
}
But, if the unchecked values aren't in $_POST, how do I know to update them???
Thanks!

value in the array. How can I get the value from $_POST even though
it's unchecked?
For example, here would be the generated form:
input type=checkbox name=cars[2] value=1Car 1
input type=checkbox name=cars[3] value=1Car 2
input type=checkbox name=cars[4] value=1Car 3
input type=checkbox name=cars[5] value=1Car 4
Then in the update I loop through:
foreach($_POST[cars] as $id=$value){
//update vehicles set value to yes or no
}
This is a good example on how *not* to trust data via form data
posted. I'm assuming you have some sort of one to many relation
going on:
table lot {
id int,
lot varchar(255) -- Lot 1
}
table vehicles {
id int,
name varchar(255) -- Car 1, Car 2, etc...
}
table lotvehicle {
lot_id int,
vehicle_id int,
}
The form value of cars[X] where X being the id of vehicle and the
value of 1 being it is selected (although with the form definition
you just want to know if if cars[X] is defined.).
So we have a form that will eventually need to knnow what values
should be selected. Potentially data alreadly exists that may have
the same records. There are two options (or perhaps more) to
approach this:
Decide as we go approach and clean up:
1) Grap the 'vehicles' currently assoicated with the 'lot'
2) if 'vehicle' is currently selected do nothing
3) if 'vehicle' is a new item we should add 'vehicle' as long as it
is a valid 'vehicle;
4) repeat 2 and 3 until we looked at all the data
5) figure out which ones should be deleted and delete them.
Forget everything, we'll add what is valid (the lazy way):
1) delete every associated record to the 'lot'
2) for each 'vehicle' add 'vehicle' as long as it is a valid
'vehicle'

Curt.

Re: [PHP] Checkboxes From Intersection Redux
Hopefully I understand your question correctly.
You have this SQL:
$media_query = 'SELECT media_id,media_name FROM media GROUP BY media_name';
And
For every media_id which is associated with $cartoon in the table
media_art, check the box; for all others leave them unchecked.
The problem is, the SQL you have is not returning every media_id
(because you're grouping on media_name). I wonder if you truly need to
group on media_name. I would assume that media_name is unique in the
media table. If it is not, then you need to rethink your table
structure. If you group on media_name and there are duplicate
media_names, you can have data like this:
media_id media_name
4Name1
16 Name1
Grouping by media_name as in your query above will produce a line like:
media_idmedia_name
4 Name1
You then output this to check boxes and use those to set the relation to
art and media. But what's the difference between media_id 4 and
media_id 16? In this case, if the database always returns the group by
this way, you would never set the media_id 16. If there is a distinct
difference between media_names with different ids, then I think you
probably need to make some changes.
That being said, if you do not need to group by media_name, then you can
simply do something like this:
select media.media_id, media.media_name, media_art.art_id, from media
left join media_art on media_art.media_id=media.media_id and
media_art.art_id=$cartoon['art_id']
Which would return a table like this if $cartoon['art_id']=15:
media_idmedia_name art_id
4 Name1 NULL
8 Name2 15
12 Name3 NULL
16 Name4 15
17 Name5 NULL
18 Name6 NULL
You could then test the output of art_id:
$checkbox_media[] = input type='checkbox' name='media_types[]'
value='{$media_rows['media_id']}'
.(rows['art_id']==$cartoon['art_id']?
checked:)./{$media_rows['media_name']} ;

Hi,

I am now making a form to edit db entries made in the previous form. I

checkboxes for all available media. For the chosen record ($cartoon,

media_id, display that media_id's media_name as a checked box.

To find out the art_id of the chosen record, the user is selecting
from a dropdown box in the form. I'm doing queries like this to make a
publisher dropdown in a similar vein:
$query = SELECT * FROM art WHERE art.art_id = '$cartoon';
$publisher_query = 'SELECT * FROM publisher';

if ($pub['publisher_id'] == $rows['publisher_id']){
$publisher_dropdown .= ' selected ';
}
$publisher_dropdown .= '' . htmlentities($pub['publisher_name']);
}
$publisher_dropdown .= '/select';

I now need to formulate how to make the checkboxes similarly. The
original setup to make the checkboxes was :

Those which were checked were inserted into media_art thusly:
media_id art_id

[PHP] Checkboxes
Hi all, I am wondering what would be the best way to handle checkboxes. I am making a site that will display several items in a 20-items-per-page format and each item will have a checkbox next to it for the user to select them. Now, what I need to do is to record the items selected by the user when clicking the Next button into a MySQL table. Should I name all the checkboxes the same, using the item IDs as values and then use an array to see which ones where selected or maybe another thing?

Re: [PHP] Checkboxes
You could name them as:
input type=checkbox name=choice[] value=1
input type=checkbox name=choice[] value=2
etc...
Then $_POST['choice'] will be an array of the boxes chosen.
$list = implode(',',$_POST['choice']);
will give you a comma separated list of all items chosen.

What you could do is this:
$query = SELECT field_name FROM table
$result = mysql( $dbname, $query );
while( $dataRow = mysql_fetch_assoc( $result )) {
echo 'input type=checkbox
name=checkboxes[]
value=' . $dataRow['field_name'] . '';
}
On submission, all your checboxes will be here:
$_POST['checkboxes']
and you can iterate through that to see what fields/checkboxes
were set. No fuss, no muss and no billion if( isset( $checkbox )).

Re: [PHP] Checkboxes
The following is completely untested but might yield the results you want.
It assigns a value to the skill array, prints the post var, and then (I
hope) advances the array pointer to the next array element:
Good luck, hugh
if (count($_POST['skill'])0)
{
for ($i=0;$icount($_POST['skill']);$i++)
{
echo input type=checkbox name=skill[($i+1)]
value=$i.$_POST['skill'].br\n;
next($_POST['skill']); // should advance the pointer to the
next element in the array
}
}

Subject: [PHP] Checkboxes
Hi
I am trying to get results form checkboxes on a form. Each checkbox is
given a value of the id of an item in a table. What I want to do is find
out what is selected and from there get the id so I can create a sql
insert
statement for each selected item.
I can get the item selected but not a value.
I am using:
PHP:
if (count($_POST['skill'])0) {
for ($i=0;$icount($_POST['skill']);$i++){
echo li$fskill[$i]\n;
}
}
inside a form
input type=checkbox name=skill[] value=1
input type=checkbox name=skill[] value=2
input type=checkbox name=skill[] value=3
I get a number of bullets representing the items I check but no value!
Thanks,
Stephen

What is $fskill? Did you forget to update your code?
echo li{$_POST['skill'][$i]}/li\n;

[PHP] checkboxes
Hello;
I want to do that:
I have two checkboxes:
if first one is checked assign the value as a;
if first one is checked assign the value as s;
if both of them checked assign th value as as
and insert the result db;
the html code:
...
tr
tdinput type=checkbox name=val value=a / AAA/td
/tr
tr
tdinput type=checkbox name=val value=s / SSS/td
/tr
...
and the PHP code:
$eval='';
if(isset($val)){
if(isset($val[0]) isset($val[1])) $eval=as;
if(isset($val[0]) !isset($val[1])) $eval=a;
if(!isset($val[0]) isset($val[1])) $eval=s;
$sql=insert into maillist (ID, postmeth) values ('$id_no','$eval');
$result=mysql_query($sql);
if(!$result) echo(ERROR);
}
I can't understand what is wrong;

Hi,
1) like Bastian already pointed out, you need to name your checkboxes
val[] in order to have PHP recognize them being an array.
2) You cannot use isset($val[0]) and isset($val[1]). If any checkbox is
clicked, $val[0] will always be set. If only one is clicked (regardless
which one) index 0 will be set and index 1 unset.
Instead, you should
if(is_array($val)){
if (in_array('a', $val) in_array('s', $val)) $eval='as';
elseif (in_array('a', $val))$eval='a';
elseif (in_array('s', $val))$eval='s';
However this would give you the very same result, but much more elegant:
$eval = join('', $val);
And it will automatically handle all further additions when $val[] might
have more possible values except 'a' and 's'.

[PHP] checkboxes and selection lists
Hi, as a beginner I find the way you declare variables through HTML-forms quite
straightforward. But the reverse, to put the same variables back into a form field is
not so obvious for selection lists and checkboxes. Would for instance this be the best
way:
SELECT CLASS=select NAME=qual
OPTION VALUE=A ?=if($qual=='A'){return 'SELECTED'}?A/OPTION
OPTION VALUE=B ?=if($qual=='B'){return 'SELECTED'}?B/OPTION
OPTION VALUE=C ?=if($qual=='C'){return 'SELECTED'}?C/OPTION
/SELECT
or would there be something more elegant?

For something like this, instead of doing all the HTML, I would set up
and array, and then loop through the array to output the HTML...
SELECT CLASS=select NAME=qual
?php
for ( $i = 0; $qual_array[$i]; $i++ ) {
if ( $_POST['qual'] == $qual_array[$i] ) {
echo ( OPTION VALUE=\ . $qual_array[$i] . \ SELECTED .
$qual_array[$i] . /OPTION\n );
} else {
echo ( OPTION VALUE=\ . $qual_array[$i] . \ . $qual_array[$i]
. /OPTION\n );
}
}
?

Re: [PHP] checkboxes and selection lists
If you have hundred thousand elements for example if you rob up for some
country select within tierce code-
I thinks doing like the following is better
echo select
optiona
optionb
...
optionzz
option selected$value
/option
/select ;
And I don't care if it could have 2 same value in the select case...
And if there aren't many value, I think the following sounds better:
echo
SELECT CLASS=select NAME=qual
OPTION .($qual==A? SELECTED:).A
OPTION .($qual==B? SELECTED:).B
OPTION .($qual==C? SELECTED:). C/OPTION
/SELECT ;

I use the following function for my check boxes in forms in PHP.
Putting your form element creation into functions or even classes makes life
so much easier when you have to validate / change code.
you'll be glad you did it

Subject: [PHP] checkboxes and selection lists
Hi, as a beginner I find the way you declare variables through HTML-forms
quite straightforward. But the reverse, to put the same variables back into
a form field is not so obvious for selection lists and checkboxes.

[PHP] checkboxes / form elements
Hello. I have a form that I would like to use checkboxes. these checkboxes are created dynamically. I've been told that if I want to manipulate each one then I should use 'name=checkbox[]' and make an array out of it. okay, fine. but how do i access them in my PHP script? I know I have to use the $_POST[] array, but this creates a multidiminsional array, yes? do i access it like $_POST[checkbox[1]]?? or $_POST[checkbox][1]?? any info is appreciated. thanks, blue -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The latter. But note, if a box isn't checked, it's not going to be
sent, so won't be in the array.
form
input type=checkbox name=StateID[] value=32 / NV
input type=checkbox name=StateID[] value=33 checked / NH
input type=checkbox name=StateID[] value=34 checked / NJ
/form
In this case $_POST['checkbox'][0] would be 33 and ...[1] would be 34.
Sometimes it's handy to identify the key upfront:
form
input type=checkbox name=StateID[32] value=608 / NV
input type=checkbox name=StateID[33] value=2 / NH
input type=checkbox name=StateID[34] value=40 checked / NJ
/form
That would yield $_POST['checkbox']['34'] = 40.
A nice way to handle incomming checkboxes is this:
while ( list($Key, $Val) = each($checkbox) ) {
# do what you need to do...
# for example, show what was sent...
echo br /$Key = $Val\n;
}
Enjoy,

Just one thing, as someone noted a week ago or so, you can't use the []
syntax *and* javascript. If you also need to process your checks from
jscript side you shall resort to some older method and have your
variables called like
input type=checkbox name=StateID_32 value=608 / NV
input type=checkbox name=StateID_33 value=608 / NV
then process it with variable variable names (the $$ syntax).

confirmation email sent to the user I manage to get the text areas to
display
in the email. How would I get the results of the checkboxes to to
display as well?
Here is a page I wrote to explore form processing. It has a simple form
on it that includes each type of form element (except file upload) and
displays back all input. It can also be used as a form target and it
will tell you what form elements were submitted.
It was written some time ago and I haven't updated it for the latest
version of PHP so it will most likely require register_globals to be on.

RE: [PHP] CheckBoxes....
Don't name the checkboxes all the same, instead:
Option1 input type=checkbox name=ck0br
Option2 input type=checkbox name=ck1br
Option3 input type=checkbox name=ck2br
Then handle it with
function getCheckboxResults($prefix=FALSE)
{
global $_POST ;
$results = NULL ; // needed for 'return' in case no items (v4.1.x)
if(is_string($prefix)){
For($i=0;$i=count($_POST);$i++){
if(isset($_POST[$prefix.$i])) $results[] = $i ;
}
} else { return -1 ; } // throw exception in script
return $results ;
}
$selectedCKItems = getCheckboxResults('ck');
if(!$selectedCKItems) makeError('Please select at least one item.');
If a checkbox is not selected, the CGI will drop it (as in, not pass on the
name/value pair - meaning the name is not there - which is why you test for
it's existance).
I didn't test that example. But if it works, the function might be a nice
addition to your (and mine) library :)
you might use it like to:
$prefix = 'ck';
Forech($arrLabels AS $i=$label)
printf('%s input type=checkbox name=%s%dbr\n',$label,$prefix,$i);
Then put this member functions in a class deinition and register instatiated
objects with a session to use them across pages. $arrLabels would be a
property of the class. 'ck' would be the value of another property. Maybe
your foreach statement was in a member function.
OK, I'll shut up now :)

Re: [PHP] CheckBoxes....
As far as I know, you can't name different checkboxes with the same name (seems odd to me to do this anyway) When you submit a form to a php page, the php page will have a variable for each input item in your form So if you have checkbox items named, a, b, c, and d, and submit a form with a and c checked, then the values of $a and $c will be on, and $b and $d will have no values It's sometimes good to use the isset() function on checkbox items In this case, isset($a) would return 1 and isset($b) would return 0 Hope that helps Jeff At 10:07 PM 3/2/2002 -0700, Ben Turner wrote: Don't checkboxes, if you name them all the same name, produce a comma delimited string in php of the values selected??? such as for 15 checkboxes with numeric values would produce a string such as ,,,1314,,,18 when the form was submited??

Re: [PHP] CheckBoxes....
Ben, Hmm I don't really understand you question, but when I had check boxes in a form, you have to name them all the same but the value all different For example: input type=checkbox name=name[1] value=value1 input type=checkbox name=name[2] value=value2 input type=checkbox name=name[3] value=value3 input type=checkbox name=name[4] value=value4 Now as far as the PHP script I think you need to use the implode(); function -GENESiS DESiGNS -Sean Kennedy -http://wwwgdesignsvcncom -- PHP General Mailing List (http://wwwphpnet/) To unsubscribe, visit: http://wwwphpnet/unsubphp

The form i am filling with the checkboxes has several checkbox options that someone can select subscription types. The sub types are all generated from a result set so that the form can grow or shrink by what is in the database and not by what is on the html code Trying to accomplish this with hand off maintenace.

[PHP] CheckBoxes and Arrays
have you tried : Input Type=\CheckBox\ Name=\ChkBox[]\ Value=\$row-ID\ -- (°-Nayco, //\[EMAIL PROTECTED] v_/_ http://nayco.free.fr Ryan Stephens [EMAIL PROTECTED] a écrit dans le message : [EMAIL PROTECTED] Im trying to output a list of options, each with a checkbox named ChkBox and with a value of the ID number from the database. This is no prob. The thing is, i want to be able to select some of those checkboxes (any number, in combination) and delete the information from the database that is associated with the ID for that CheckBox. Example of input tag: -- echo TDInput Type=\CheckBox\ Name=\ChkBox\ Value=\$row-ID\\n; --- Now i thought that if i selected say items 1, 2, 3 from the list (and there IDs are 1, 2, 3) then When i submit the form a comma delimited string would be created (an array even not sure what it is). How would i loop through this list and break it apart so i can delete each record from the database that was selected.

Name each checkbox ChkBox[] ... the brackets are the key.
When the form is submitted, you'll have an array called $ChkBox that will
contain the data only from the checked checkboxes. You can loop over that
array pretty simply.
for( $i = 0; $i sizeof( $ChkBox ); $i++ ){
print( $ChkBox[$i] . was checkedbr );
// Delete the row from the database, etc ...

[PHP] checkboxes part II
Hi all, maybe this example will show you what is the problem. Try to unselect some of the checkboxes and you will see that there is some magic in here. I want to have per id if the selectbox is selected or not. The test.html will be generated from mysql when test.php is working fine. I'm getting mad of this...

I would recommend generating these checkbox / text input field combos within
a loop and assign to separate arrays with the same key so you can match them
up when processing later. Like this:
$num_inputs = 5; // if you want 5 sets of checkboxes and text inputs.
for ( $i = 0; $i $num_inputs; $i++ )
{
echo "input type=checkbox name=checklist[$i]Cb $i input type=text
name=text[$i]\n";
}

Re: [PHP] checkboxes into MySQL
it took me a while to find this out, too. If you have say, 5 checkboxes, name them like so: input type="checkbox" name="musicians[]" value="monk" input type="checkbox" name="musicians[]" value="trane" input type="checkbox" name="musicians[]" value="miles" input type="checkbox" name="musicians[]" value="dizzy" input type="checkbox" name="musicians[]" value="bird" when submitted, in the script processing the form, check the array $musicians[]. The checked selections will be included as elements. So if trane and bird were checked, you will have a 2-element array in $musicians[]. $musicians[0] == "trane" $musicians[1] == "bird" HTH.
