Re: [PHP] iterate javascript verification
Hey guys,
Thanks for the input! This is pretty nice, and DOES work. I like the fact
that the fields have been into an iterative array. It's a very elegant
solution. However the problem with this approach is that if you load the
page directly it works. But if you call the page from the index.php page
you get an initial error on all fields as they are all quite naturally
empty when you first load the page.
Here's the index.php page. All it is is HTML, no php:
html xmlns=http://www.w3.org/1999/xhtml; xml:lang=en lang=en
head
meta http-equiv=Content-Type content=text/html; charset=utf-8 /
titleLDAP Request Form/title
body
centerh3LDAP Request Form/h3
form name=form_request method=post action=ldap.php
onsubmit=return validateForm()
label for=requestor_emailYour Email Address:/labelbr /
input type=text required id=requestor_email name=requestor_email
/br /br /
label for=num_formsHow Many Forms Do You Need:/labelbr /
input type=text required maxlength=2 size=5 id=num_forms
name=num_forms /br /br /
input type=submit name=submit value=Submit /
/form/center
/body
/html
And here is ldap.php as was suggested:
body
?php
if (isset($_POST['submit'])) {
$requestor_email = $_POST['requestor_email'];
$num_forms = $_POST['num_forms'];
}
echo centerYou will be creating $num_forms accounts
today./centerbr /;
for($counter = 1;$counter=$num_forms;$counter++) {
echo 'centerform name=ldap_accounts method=post
action=sendemail.php onsubmit=return validateForm()';
echo 'br /br /';
echo Enter user: $counterbr /br /;
echo label for=\first_name_.$counter.\First Name:/labelbr

echo input type=\text\ id=\first_name_.$counter.\

echo input type=\hidden\ id=\requestor_email\

echo input type=\submit\ name=\submit\ value=\Create Ticket\ /;
echo /form/center;
?
Why this happens when you call the ldap.php page from index.php but not
when you load the page directly beats me. But maybe someone can shed some
light on that?
Thanks!

Re: [PHP] iterate javascript verification
When you do validation of the form in the same script that shows the
form, the normal way to do this is
?php
if (isset($_POST['submit'])) {
//
// validation here
//
}
?
This won't work if you're getting to the page via another form, since
the $_POST['submit'] is set. There two ways of avoiding this:
1) use hidden fields in each form to indicate which form was submitted
2) use a different name for each form's submit button and use that in
the above code

[PHP] iterate javascript verification
Hello list,
I have a php script that creates a variable number of forms based on a
$_POST variable from a preceding page. It then takes the data input into
the form and neatly packages the result into an email sent to an email
address (eventually to be a ticketing system).
Almost everything on the page works great. The only thing I can't seem to
get working is how to verify that the fields in the form are not left empty
using javascript. The syntax I'm using seems like it should work, however
when I leave one or more of the fields empty, the email gets sent anyway
with the missing data.
Here's the app I was hoping someone might be able to suggest a successful
approach:

Re: [PHP] iterate javascript verification
You do realize that you shouldn't rely on Javascript to validate
values returned in a form? Also, if you use HTML5, you can use the
required attribute in the input tag and the browser won't let a
user submit a form with a required field not filled. Of course, you
should still validate within your PHP script, in case a user is using
a browser that doesn't understand HTML5.

Re: [PHP] iterate javascript verification
You can validate via JS if required, for example: (JS CODE):
if(element.value.length == 0){
// handle 0 length value
}
I do agree with Ken that you SHOULD NOT perform JS validation. It is
preferable to use php or the new HTML5 features. JS can be turned-off by
the user which will make JS validation impossible.

Re: [PHP] iterate javascript verification
I took your code and modified it to use HTML5 validation (and few
other changes). You can see the results at
http://my-testbed.com/test1/form_validation.phphttp://my-testbed.com/test1/form_validation.php
My code follows:
?php
$fields =
array('first_name','last_name','department','title','email','phone');
$num_forms = 1;
$tmp = array();
$errors = array();
if (isset($_POST['submit'])) {
$requestor_email = $_POST['requestor_email'];
$num_forms = $_POST['num_forms'];
for ($i = 1;$i = $num_forms; ++$i) {
foreach ($fields as $fld) {
if ($_POST[$fld][$i] == '') {
$errors[] = ucwords(str_replace('_','
',$fld)) . for account $i can not be blank;
}
}
}
}
if (!empty($errors)) {
$tmp[] = The following fields are in error:br;
$tmp[] = implode(br\n,$errors);
$tmp[] = br;
}
$tmp[] = div style='text-align:center'You will be creating
$num_forms accounts today./divbr;
$tmp[] = 'div style=text-align:centerform
name=ldap_accounts method=post action=';
$tmp[] = 'br /br /';
for($counter = 1;$counter=$num_forms;$counter++) {
$tmp[] = Enter user: $counterbr /;
$tmp[] = label for='first_name_$counter'First Name:/labelbr/;
$tmp[] = input type='text' required
id='first_name_$counter' name='first_name[$counter]'br /br /;
$tmp[] = label for='last_name_$counter'Last Name:/labelbr /;
$tmp[] = input type='text' required
id='last_name_$counter' name='last_name[$counter]' /br /br /;
$tmp[] = label for='department_$counter'Department:/labelbr/;
$tmp[] = input type='text' required
id='department_$counter.' name='department[$counter]' /br /br /;
$tmp[] = label for='title_$counter'Title:/labelbr /;
$tmp[] = input type='text' required id'title_.$counter'
name='title[$counter]' /br /br /;
$tmp[] = label for='email_.$counter'Email:/labelbr /;
$tmp[] = input type='email' required id='email_.$counter'
name='email[$counter]' /br /br /;
$tmp[] = label for='phone_$counter'Phone:/labelbr /;
$tmp[] = input type='text' required id='phone_$counter'
name='phone[$counter]' /br /br /;
}
$tmp[] = input type='hidden' id='num_forms' name='num_forms'
value='$num_forms' /br /br /;
$tmp[] = input type='hidden' id='requestor_email'
name='requestor_email' value='$requestor_email' /;
$tmp[] = input type='submit' name='submit' value='Create Ticket' /;
$tmp[] = /form/div;

You will notice that I moved the code for the form to above the HTML
section. I believe that very little PHP should be interspersed with
the HTML -- it makes for cleaner code. You can use single quotes
around form attributes so you don't have to escape the double quotes.
The names in the form are now arrays. This makes your life much
easier when extracting the values later in PHP.
When you check the page in a HTML5 aware brower, you will see how the
validation is done.

You can validate via JS if required, for example: (JS CODE):
if(element.value.length == 0){
// handle 0 length value
}
I do agree with Ken that you SHOULD NOT perform JS validation. It is
preferable to use php or the new HTML5 features. JS can be turned-off by
the user which will make JS validation impossible.

Hello list,
I have a php script that creates a variable number of forms based on a
$_POST variable from a preceding page. It then takes the data input into
the form and neatly packages the result into an email sent to an email
address (eventually to be a ticketing system).
Almost everything on the page works great. The only thing I can't seem to
get working is how to verify that the fields in the form are not left empty
using javascript. The syntax I'm using seems like it should work, however
when I leave one or more of the fields empty, the email gets sent anyway
with the missing data.
Here's the app I was hoping someone might be able to suggest a successful
approach:
html
head
titleLDAP Form/title
body
?php
if (isset($_POST['submit'])) {
$requestor_email = $_POST['requestor_email'];
$num_forms = $_POST['num_forms'];
}
echo centerYou will be creating $num_forms accounts
today./centerbr /;
for($counter = 1;$counter=$num_forms;$counter++) {
echo 'centerform name=ldap_accounts method=post
action=sendemail.php onsubmit=return validateForm()';
echo 'br /br /';
echo Enter user: $counterbr /;
echo label for=\first_name_.$counter.\First Name:/labelbr
/;
echo input type=\text\ id=\first_name_.$counter.\
