I hate arrays. :D
Here's a small snippet showing how it works, I hope:
foreach ($DPRpriority as $item = $value) {
echo li .$item.: .$value['name']. selected:
.$value['selected']. /li\n;
}
Question 1: when did we have to add [] to a input name to turn it into
an array?
input type=checkbox name=DPRlocationdetails[] value=Unknown
According to phpinfo() it still comes out as
$_POST['DPRlocationdetails'] without [].
Are the [] necessary?
--
Question 2:
I was looking at some code in the Manual, where someone used isset and
is_array.
How necessary is if(isset($_POST['DPRlocationdetails']))
and then to use: if(is_array($_POST['DPRlocationdetails']))
That seems like over kill?
--
Question 3:
My code works, perfectly. In this case, I decided to attack some
check-boxes first. The resulting function will work for select
multiple too..
Does anyone see me doing something wrong in my code below?
My questions are:
Is this the only way to pass Unknown, Family Home or Apartment
into the function?
Is this correct?
if ($_POST['DPRlocationdetails'] == Unknown)
Somebody once told me I had to do it this way?
if (Unknown == $_POST['DPRlocationdetails'])
John
snip---
form action=foo.php id=DPRform method=postinput value=Update
type=submit
input type=checkbox name=DPRlocationdetails[] value=Unknown ?php
filter_value($_POST['DPRlocationdetails'],Unknown); ? Unknown
input type=checkbox name=DPRlocationdetails[] value=Family Home
?php filter_value($_POST['DPRlocationdetails'],Family Home); ?
Family Home
input type=checkbox name=DPRlocationdetails[] value=Apartment
?php filter_value($_POST['DPRlocationdetails'],Apartment); ? Apartment
/form
?php
function filter_value($tofilter,$tofind) {
foreach($tofilter as $value){
if ($value == $tofind) echo checked;
}
}
?
The [] are necessary if there are going to be multiple occurrences of an
input with the same name, hence the [] to allow your php script to
extract all of the occurrences.
Using isset and is_array comes in handy to help you handle the incoming
var properly. If it IS set, you then have to check if there is only one
value (hence a string) or if there are multiple values (an array).
#3 - no idea what you are asking.

As a look on qa.php.net or the box on the top right of php.net tells we
have RC2 for both out, you can also see in the repo that the release is
being prepared:
http://git.php.net/?p=php-src.git;a=blobdiff;f=NEWS;h=d3a3e9fa0f344d9b736ea17ce408df6b02e8b561;hp=c4262020de69b7a93b8fcf4923e85194756435a7;hb=0183c29cb3921926855ed6f5e7cea7851fb8a5a1;hpb=904d2202eaecb7c300c36f37ebc5503513220c09
Please test the RCs and provide test feedback. Thanks.

We had 5.4.12 RC2 last week, due to recent SOAP fixes we had to pull in,
and will have 5.4.12 GA this week.

What am I doing wrong? input type=button name=button2 id=button2 value=Print Mode onclick=formSubmit() I really wanted to use a button to pass a different condition than a input type=submit Use a different value or name on the input type=submit/ button. Don't use JavaScript to trigger the form like that. Its not necessary and will bite you in the ass if ypu get a visitor who browses without JavaScript, which can include security aware users, blind users, etc Thanks, Ash http://www.ashleysheridan.co.uk -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Try $_POST['button2'] Best regards. Steven $_POST['button2'] does not exist. I'm using radio to get aorund it for now. A button would have been cleaner. You were given the answer, did you not try it? Starting with the code in your original post: 1) Change the type to submit. 2) Remove the onclick. 3) Job done! -Stuart -- Sent from my leaf blower -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Do I need to put it in another textarea and declare it hidden? Here is a quote: If the element is mutable, its value should be editable by the user. User agents must not allow users to insert LF (U+000A) or CR (U+000D) characters into the element's value.

Re: [PHP] parsing select multiple=multiple

I hate arrays. :D
Here's a small snippet showing how it works, I hope:
foreach ($DPRpriority as $item = $value) {
echo li .$item.: .$value['name']. selected:
.$value['selected']. /li\n;
}
Question 1: when did we have to add [] to a input name to turn it into an
array?
input type=checkbox name=DPRlocationdetails[] value=Unknown
According to phpinfo() it still comes out as $_POST['DPRlocationdetails']
without [].
Are the [] necessary?
[] are necessary when you want to return multiple values for a form
field, or collection of form fields such as checkbox. AFAIK, this has
always been the case with PHP. See
https://gist.github.com/tamouse/5002728

Question 2:
I was looking at some code in the Manual, where someone used isset and
is_array.
How necessary is if(isset($_POST['DPRlocationdetails']))
and then to use: if(is_array($_POST['DPRlocationdetails']))
That seems like over kill?
It's more defensive, in the case where someone may be by-passing your
form to send things in.

Question 3:
My code works, perfectly.
Then there must be no questions. :)
In this case, I decided to attack some check-boxes
first. The resulting function will work for select multiple too..
Does anyone see me doing something wrong in my code below?
My questions are:
Is this the only way to pass Unknown, Family Home or Apartment into
the function?
Is this correct?
if ($_POST['DPRlocationdetails'] == Unknown)
Somebody once told me I had to do it this way?
if (Unknown == $_POST['DPRlocationdetails'])
In this scenario, these are equivalent. There is no preference of one
over the other.
I *have* heard claims that something like this is preferrable, though:
if (FALSE === $variable)
But I think that may have been due to some misunderstanding of
precedences in the following sort of scenario:
if (FALSE === ($result = some_function())
where if done this way:
if ($result = some_function() === FALSE)
was giving them bad results.
