如果所有内容都以表格填写，请转到PHP中的新页面

Question

I have a problem, I want to make form and I want to check it with php script if it's filled. I found a solution, but Is there any other way(more 'professional') to make it. Here is my code now:

$x = 0;
    if(empty($name)){
    $nameKL = "No name";
    } else {
    $x = $x + 1;
    }

    if(empty($price)){
    $priceKL = "No price";
    } else {
    $x = $x + 1;
    }

    if($x == 2){
    header('Location: nextpage');
    }

So the Idea is: If checked variable is not empty I give x=x+1 , If its empty I return error. I have two fields in form, so If x==2 everything is okay. else errors are echo'ed in html form. So is there any smarter way to do this? I can't think out any on my own...

PS. It's only part of my code, and I need help only with this logical part

Answer 1

Make an array of elements.

<input type="text" name="formadata['fname']" />
<input type="text" name="formadata['lname']" />
<input type="text" name="formadata['age']" />

in PHP you can loop all elements

$inputs = $_POST['formdata'];
$errors = array(
              'fname' => 'First name message',
              'lname' => 'Last name message',
              'age' => 'Age message',
          );
foreach($inputs as $input) {
    if(empty($input)) return $errors[$input];
}

So this way you can manage to check whether input is empty or not in PHP

Answer 2

Using Ternary Operation. Please check below simple code.

$x = 0;
$nameKL = empty($name) ? "No name" : $name;
$priceKL = empty($price) ? "No price" : $price;


if($nameKL && $priceKL){
header('Location: nextpage');
}

Answer 3

$nameKL = empty($name) ? "No name" : $name;
$priceKL = empty($price) ? "No price" : $price;


if(empty($name) && empty($price)) {
    header('Location: nextpage');
}

Answer 4

Well, I found the solution on my own. I set up a variable that has a true value at the beginning and then:

$validate = true;

if(empty($name)){
$nameKL = "no name";
$validate = false;
}

if(empty($price)){
$priceKL = "no price";
$validate = false;
}


if($validate == true){
header('Location page.php');
}
