I thought of JavaScript also but it would have to be a “if $row[33] then

[PHP] checkbox unchecked
I have now tried to add many of the security hints on a web page and
come to a problem.
I am checking if the allowed fields match the sent fields.
From the database I get the information if a checkbox is checked or not:
?php if($DB_a ==y) {
$checked=checked;
} else {
$checked=;
}
?
input type=checkbox name=R_a value=y ?php echo $checked ?
If the user takes out the checkmark the value will become and the
field will not submitted which results in a missing field.
$allowed = array();
$allowed[]='form';
$allowed[]='R_a';
$allowed[]='R_b';
$sent = $array_keys($_POST);
if($allowed == $sent) {
... do some checking ...
} else {
echo Expected input fields do not match!;
}
break;
How can I force a n for not checked in the input field? or how can I
solve that?

Re: [PHP] checkbox unchecked
First of all, using y and n for boolean values (such as a checkbox) is
very sloppy. n is boolean True. A boolean value should evaluate correctly
in a boolean context. For that, you should use 1 and 0 for your values.
What I usually do is this:
input type=hidden name=foo value=0 /
input type=checkbox name=foo value=1 ?php echo $checked; ? /
Then when it gets submitted, foo will get the value of the form element that
was submitted last that has a value. That is, if the checkbox is checked
then foo will be 1, otherwise it will be 0. That gives you a nice, clean
boolean value you can rely on being present (mostly g).

Re: [PHP] checkbox unchecked
I did once, if I remember once, this strategy:
input type=hidden name=R_a value=n
input type=checkbox name=R_a value=y ?php echo $checked ?
If checked, you will have value y. Though, if unchecked, or it was
checked and visitor unchecked, the value should be n.

Re: [PHP] checkbox unchecked
Just to add my two cents -
I don't think it matters much what tokens you use to represent true
or false, since you're going to be explicitly checking them on the
server end anyway. I can't see much difference in principle between,
for example:
if ($_GET['foo'] == 'y')...
and
if ($_GET['foo'] == '1')...
or even
if ($_GET['foo'] == 'Oui')...
One should really not do be doing just
if ($_GET['foo'])
anyway. Checking that a specific value is passed, rather than just
some value that PHP evaluates to true or false, is one way to catch
possible form hacking. For general reference, there are a number of
php security howtos out there on how to sanitize user input, but I'll
leave finding them as an 'excercize for the reader' at the moment. I
suppose using 0/1 does have the advantage of 'doing the right thing'
if a if ($_GET['foo']) creeps into your code, though. As would
using 'Y'/''.
That being said, I've used 0/1 along with y/n in the past; it depends
on whether I'm thinking like a programmer or a human ;)

Not that you said otherwise, but if the programmer does not set the
value for a checkbox, html will provide values -- that may lead to
confusion for newer programmers.
See here:
http://webbytedd.com//checkbox/
If you will note, without specifically setting the value, html will
return on.
Also, I'm sure it's an oversight, but your code above should be:
?php if ($foo) echo('checked'); ?

[PHP] Checkbox Hidden Field to Delete Row
Ave,
I¹m stuck on a problem here.
I have a file manager kind of application and I¹m trying to add the
functionality to delete multiple files.
Basically, there¹s a bunch of rows generated dynamically. Each row has a
checkbox for ³Delete² option, and a hidden field which contains the name of
the File associated with the record. If a user checks a checkbox to delete
certain rows, it should be able to delete those rows from mySQL as well as
delete the files associated with that record.
I created both the checkboxes the hidden fields to be Arrays. I run a loop
to delete all rows (based on ID¹s) where the checkbox was Checked. It does
that part fine... The problem is linking the Filename array to the Checkbox
Array. It deletes the first two files uploaded no matter what rows are
checked. Basically, the Filename array is not associating with the Checkbox
array. So if a person checks the 3rd and 5th checkbox... The 3rd 5th row
is deleted from mySQL, but the 1st and 2nd file is deleted, not the 3rd
5th.
Following is my code to generate the checkboxes hidden fields...
td width=15span class=\style11\ input
type=checkbox name=thisID[] value=$myrow[ID]input type=hidden
name=\PF[]\ value=\imsafm/$showfilesuser/$myrow[filename]\input
type=hidden name=login value=$loginINPUT TYPE=hidden name=showfilesuser
value=$showfilesuser/td
Following is the code to delete the checked rows/files...
for($I=0;$Isizeof($thisID);$I++) {
$sql = DELETE FROM file WHERE ID='$thisID[$i]';
$result = mysql_query($sql) or die(Fatal Error: .mysql_error());
$thefile = $PF[$i];
unlink($thefile);
}
I have no clue what to do... It¹s just not working out.

Re: [PHP] Checkbox Hidden Field to Delete Row - SOLVED
Ave,
I spent 3 hours trying to find or develop a solution for this problem... And
believe it or not, within 3 minutes of sending the problem to the mailing
list, I actually generated a solution!! Ray, you’re spot on with what’s
actually happening, but this is what I did to resolve it...
Here’s my code to generate the Dynamic Row with Checkboxes:
td width=15span class=\style11\ input type=checkbox name=thisID[]
value=\$myrow[ID]#imsafm/$showfilesuser/$myrow[filename]\input
type=hidden name=login value=$loginINPUT TYPE=hidden name=showfilesuser
value=$showfilesuser/td
I completely eliminated the Hidden field... Instead, added the value of both
the Row ID the Filename to the checkbox, with a seperator “#”.
Here’s my code to delete the Row Corresponding File:
foreach($thisID AS $value) {
$pieces = explode(#, $value);
$sql = DELETE FROM file WHERE ID='$pieces[0]';
$result = mysql_query($sql) or die(Fatal Error: .mysql_error());
$thefile = $pieces[1];
unlink($thefile);
}
As you can see, I basically explode the Array on the “#” seperator, and
delete the Row File. Is working like a charm!!

Tad different, but that will definitely work as well. It's a long shot, but
just make sure that filenames don't have a # in them.

foreach ($_POST['chkmodels'] as $c)
{
echo(br value: . $c);
}
this is fine.
but what I want to clarify is that if I change my PHP echo statement
to:
echo(input type=checkbox name=chkmodels value= . $row['models_id'] .
. $row['models_type'] . br);
basically without the [] then it is still recognised as an array. But
when the array is passed back it is returned as a string separated by
commas. Then I should use the split() function to create an array.
IE:
$modelsArray = split('[,]', $chkmodels);
however when I try the second way (without the [])
like this:
if(isset($_POST['chkmodels']))
$selModels=$_POST['chkmodels'];
else
header(Location: ../freesample.php);
if(isset($selModels))
{
echo(selmodels: .$selModels);
$selModelsInd = split('[,]',$selModels);
echo(brInd modesl . $selModelsInd);
foreach ($selModelsInd as $c)
{
echo(br value: . $c);
}
}
I get the following results, when I select 2 checkboxes:
selmodels: 2
Ind modeslArray
value: 2
this is wrong and should output the following:
selmodels: 2
Ind modeslArray
value: 1
value: 2
as the values of the selected checkboxes are 1 and 2 and also there are
two that are selected.
Here is the OT part. how do I reference the checkboxes in javascript if
the chkmodels[] is used?
I have tried many things like:
myCheckboxArray = document.forms[0].elements[chkmodels[]];
and
myCheckboxArray = document.frmft[0].elements[chkmodels[]]; //where
frmft is the name of my form.
If someone could please advise me as to what I'm doing wrong or why the
information is not being outputted as expected, that would be really
helpful.
thanks in advance
Angelo

No, this is incorrect. You will see only the last value selected, returned
as a simple scalar. PHP doesn't do automatic array-ification of multiple
values -- that's why you need the [] in the name attribute.
Cheers!

If you leave off the [], then only the last checkbox value remains in $_POST['chkmodels']. It is not passed as a comma separated string. If you look at the query string, you'll see something like this: ?chkmodels=1chkmodels=2 which means PHP makes $_POST['chkmodels'] equal to 1 for the first variable, then sets the same $_POST['chkmodels'] equal to 2 for the second variable in the query string. End result is one value (not an array) remaining in $_POST['chkmodels']. -- ---John Holmes...

[PHP] checkbox: was it shown or not?
hi, if i understand well, a checkbox in a form is only send on to the next page when it is checked: so the next page will only see a value in $_POST['checkboxname'] if it is set: else it is not set.

Re: [PHP] Checkbox
Hello From a usability standpoint showing a checkbox that cannot be unchecked renders the checkbox obsolete. The consquence is not to show a checkbox at all. If you need an uncheckable checkbox because of licence aggreements or something like that. Or privacydeclaration type checkbox. Make it checkable but check on the server side if it is checked. If not render an error message to the client telling them why you can't process the form/data because the checkbox is unchecked. That way it is still up to the user to decide what he wants to do. Another alternative is to build a button that has to be pressed to continue which does the same as the checkbox. The important thing is: 1. Don't take away the users freedom of choice (checking / not checking) 2. Make the user feels he is in control (even though he isn't ;) ) 3. Only put up control elements that actually enable the user to take control Basically all three points are the same. I suggest to read up on usability issues. Just do a google on usability and software. Cause usability is one of the things most of the webprogrammers get wrong... It's not important what your intention is rather what the user intents to do! Please remember this is my opinion so take it or leave it. ;) Regards Stefan

Just so long as you check the data after it's submitted again and determine whether the value should have been allowed to change or not. If it wasn't allowed to change, then don't accept the value that was passed (because it may of changed regardless of what measures you take).

RE: [PHP] Checkbox
Just be wary that not all browsers will honor the readonly flag (Netscape 4 for example). In looking at this I found a tutorial at http://www.estek.net/estek/idocs/forms/_INPUT_DISABLED.html . I tested it in IE 6, NS 7.02 and Opera 7. None of these browsers prevented me from checking and unchecking the box. Only the DISABLED flag does. Readonly apparently prevents the user from altering the value of the input field. -Original Message- From: Tim Burden [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 26, 2003 11:25 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] Checkbox Just using the readonly flag in the input tag is the easiest method, I think. - Original Message - From: Reuben D.

There are form/form tags around input type=checkbox ... What are
they
supposed to do?
I think your problem lies there, because ids[] belong to this new form not
to the first one and then ids[] cannot be set.
Secondly, method='post' inside input does nothing.
Hope that helps.

Re: [PHP] Re: PHP checkbox/hidden field question
You are wrong, this is from HTML 4.01 specification:
value = /cdata/ cid:[EMAIL PROTECTED] [CA]
cid:[EMAIL PROTECTED]
This attribute specifies the initial value cid:[EMAIL PROTECTED] of
the control. It is optional except when the
type cid:[EMAIL PROTECTED] attribute has the value radio or
checkbox.
Upon submiting a form, only successfull checkboxes are submited,
so on the next page you only need this loop:
foreach($d_c_arr as $i) {
echo 'input type=hidden name=d_c_arr[] value='.
htmlspecialchars($i).'';
}
$d_c_arr contains only checked checkboxes.

cid:[EMAIL PROTECTED] of
the control. It is optional except when the
type cid:[EMAIL PROTECTED] attribute has the value
radio or checkbox.
Upon submiting a form, only successfull checkboxes are submited,
so on the next page you only need this loop:
foreach($d_c_arr as $i) {
echo 'input type=hidden name=d_c_arr[] value='.
htmlspecialchars($i).'';
}
$d_c_arr contains only checked checkboxes.

As you might know, checkboxes don't have the VALUE attribute. HTML
won't
even submit the VALUE attribute to the next page. You will only have an
array containing 0's and 1's, the results of the checkboxes. So, on the
next
page, you will have to lookup the values again.
Then print the hidden input's to the page in a for loop, while looping
trough $d_c_arr.

Re: [PHP] checkbox = POST = array??
I'm doing something very similar on a project I'm working on, except I'm
using radio buttons. I'm not quite sure what are using the ID for (for
style sheets or a data ID). If you are using it as a data ID, then you
can make it part of the topic[] array. So it would look like this:
input type='checkbox' name=topic['45'] value='a value'
Then to process the array, you would do something like this:
while (list($checkboxID,$checkboxValue) = each $topic) {
// Your process code
}
Each check box is then referenced by the two variables $checkboxID and
$checkboxValue. There are a number of ways ou can do this, really any
way you would process and array (i.e. foreach). I prefer this way
because I can give logical names to the array elements I am using.

Re: [PHP] Checkbox Initial Value based on record in db
It will only be checked if you put CHECKED in your HTML.
if($myrow['abb'] == 1) { echo checked ; }
Add that into your input element.

No, that wouldn't workto have a checkbox autochecked the HTML must be
similar to
input type=checkbox name=abb value=?php echo $myrow['abb']; ?
checked
So a sample coding might be
input type=checkbox name=abb value=?php echo $myrow['abb']; ? ?php
if ($myrow['abb']) { echo 'checked'; } ?

[PHP] checkbox doesn't pass?
I have a html form with some text (T1) and checkbox (C1) fields to pass
it to a php script.
Accessing text fields has no problem.
There is a problem when I use
$C1=$HTTP_POST_VARS['C1']
to take the value of C1 (ON)
If it is not checked, then it is not set at all. (??why??)
So I use :
if (!isset($C1)) { $C1=0 }
but still I get an warning that C1 is not set, on my screen.
That happens before the use of isset function.
How can I susspent this warning message?
What's wrong?

Makis,
why do you use $HTTP_POST_VARS? Do I miss something?
if you have a form and send it, the vars have the same names as in your
form, will say if your checkbox name=foo value=someval will be transmitted,
then in the following page there´s a var named $foo. and the value will be
someval
if the box is checked, otherwise there´s no (or NULL or FALSE ???) value in it.
I personally prefer put checkbox vars (if there are several) in an array
f.e. $foo[]
In the following page I just scan the array and if there´s a value in a field
thats fine.

RE: [PHP] checkbox doesn't pass?
You should use $HTTP_POST_VARS (or $_POST) all of the time. There's security risks in
using register_globals. It's not risky in all cases. But register_globals will allow
arbitrary variables to be added to into the name space of your script by simply
putting them on the uri. Code not expecting such input, and expecting variables not
to exist unless the script set them may behave unexpectedly.
The reason the variable is not set is that the checkbox isn't checked. You can test
the variable with isset(), or empty() before you use it so you don't get the warning.
To learn what your script it seeing when you submit the page, do a:
foreach ($HTTP_POST_VARS as $key = $value) {
echo Key: $key Value: $valuebr\n;
}
at the top of your action handler script, and watch the variables come in when you
check or not check the checkboxes. Once you understand that, then write the code to
handle the situation.

Unchecked checkboxes pass no values, that's how it works. It's either set or not. Default value for a checkbox is 'on' although you can change that. isset() will work fine. Regards, Philip -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] checkbox validation
Hi jacky,
put an empty square bracket after the variable name as follows:
input type=checkbox name=id[ ] value=$id
assuming that your above statement is in a loop we will have following
structure:
*
form
input type=checkbox name=id[ ] value=$id
input type=checkbox name=id[ ] value=$id
input type=checkbox name=id[ ] value=$id
etc...
submit button
/form
now when you submit the form, an array named id[ ] will be posted .
this array will contain the number of elements/checkbox which were checked
on.
so out of 25 checkboxes if you select only 5 checkboxes, then the size of
the array id[ ] will be only 5.
so with another loop you can retrieve all the values as follows:
***
$i=0;
while($isizeof($id):
$id[$i]==blah;
$i++;
endwhile;
***
sorry for the poor explanation but i hope this will serve your purpose. if
you have any queries with this feel free to contact me.
regards
keyur

One possibility:
Add a hidden field in the form and write all names of the checkboxes in
it, separated by a semicolon, for example.
-
form
$query="select id from foo";
$result=($query,$con);
while ($row = mysql_fetch_array($result))
{
input type="checkbox" name="$id" value="on"
$names_of_checkboxes.=$id.";";
}
input type="hidden" name="names_of_checkboxes" value="? echo
$names_of_checkboxes; ?"
submit button and stuffs here...
/form
---
Then, in the next page you just do following:
---
$checkboxes_names_array=explode(";",$names_of_checkboxes);
for($x=0;xcount($checkboxes_names_array);$x++)
{
if($$checkboxes_names_array[$x]=="on")
// box checked
