$a = 0;

if (!empty($_POST['text1'])) {
$a++;
}
if (!empty($_POST['text2'])) {
$a++;
}
if (!empty($_POST['text3'])) {
$a++;
}
if (!empty($_POST['text4'])) {
$a++;
}
if (!empty($_POST['text5'])) {
$a++;
}
if (!empty($_POST['text6'])) {
$a++;
}

echo $a;


Is a simple way to figure out the number of not empty fields. Short of that, you could loop over the entire form to find the not empty fields.

hi
this way is correct, but if i have 60 item in $_POST i most write Sixty Times of "if (){}" condition
Is there another way?
If I am using a loop in the name must be different in digits
but I have either a different name
for example 'name' 'last name' 'email' ...

You've just changed your requirements ;)

Bernie's loop suggestion works fine if the name fields were sequentially numbered, like the ones you stated in your opening post. You could increment the number part of "text1", "text2", "text3" too.

To answer the revised query, you could check differently named form fields like this : http://stackoverflow.com/questions/3190464/php-check-if-any-posted-vars-are-empty-form-all-fields-required

I forgot to include the empty count - something like;

// Required field names
$required = array('login', 'password', 'confirm', 'name', 'phone', 'email');

// Loop over field names, make sure each one exists and is not empty
$error = false;
$a = 0;
foreach($required as $field) {
if (empty($_POST[$field])) {
$error = true;
$a++;
}
}

if ($error) {
echo "All fields are required.\n";
echo "$a fields are empty.";
} else {
echo "Proceed...";
}

Untested - on iphone.

You always use HTML arrays and access the values as an array like this:
