How to use foreach input[type=submit]?

Question

In my form there are multiple submit buttons and each submit button should redirect the page to same location but the content changes based on the session variable set. But writing isset(); for each submit button is difficult. So I am trying to write a loop where foreach input type submit the loop should write the isset(); function.

My form is like:

<form method="POST">
    <input type="submit" name="type1" value="type1" > <br/>
    <input type="submit" name="type2" value="type2" >
</form>

And I have tried to mix up JQUERY with PHP to achieve this, like:

<?php
  echo '<script>
  $("input:submit").each(function(){
  var inputName = $(this).attr("name");' ;
                    
  $inputName = print 'document.write(inputName);';
            
  if(isset($_POST[$inputName])){
    $_SESSION["value"] = $inputName;
    header('Location:somepage.php');
  } 
            
  echo '  });
        </script>';
        
?>

But this is not working.

Kindly help me to achieve the loop foreach input which has type as submit.

You can't write PHP in JavaScript. PHP runs on the server, JS runs on the client. — Barmar, Jun 14 '21 at 17:50
Does this answer your question? [How do I pass variables and data from PHP to JavaScript?](https://stackoverflow.com/questions/23740548/how-do-i-pass-variables-and-data-from-php-to-javascript) — Kinglish, Jun 14 '21 at 17:51
In the submit button you can put a `formaction` atttribute. It will then submit to that URL instead of the action of the form. — Barmar, Jun 14 '21 at 17:51
Your loop is redirecting to the same `somepage.php` for each submit button. I thought you said each button should redirect to a different location. — Barmar, Jun 14 '21 at 17:53
@Barmar, I tried achieving my aim mixing jquery and php. Now I am looking on how to achieve this using php only. But I am stuck!! — user16225210, Jun 14 '21 at 17:56
@Barmar, yes like the page redirect's to same page but the content changes based on the session variable set. Sorry for that!! — user16225210, Jun 14 '21 at 17:57
Why do you give them different names? Why not use the same name but a different value? — Barmar, Jun 14 '21 at 18:00
Only one submit button can be clicked and they all have a different value. Just use an array and get the value. — AbraCadaver, Jun 14 '21 at 18:04

Use an associative array that lists all the possible submit button names. Check for it and then set the session variable.

$redirects = ['type1', 'type2'];

foreach ($redirects as $name) {
    if (isset($_POST[$name])) {
        $_SESSION['value'] = $name;
        break;
    }
}

Yes, this would also work. But again here I have to type each and every type in the array, right? – user16225210 Jun 14 '21 at 18:18
Yes. You have to provide the list somewhere. You could use the same array when creating the buttons in the HTML. – Barmar Jun 14 '21 at 18:20

you can use php script only example :

   <?php
   if(isset($_POST['type'])){
      $a = $_POST['type'];
       foreach($a as $b){
       $c = preg_replace("/[^a-z0-9]+/i", "-", $b);
    }
    $type = rtrim($c, '-'); //output is type-num ex type-1
    $_SESSION["value"] = $type;
    if(isset($_SESSION['value'])){
      //  header('Location : page.php');
       }
    }
//cahnge 10 to how many input you need
echo'<form method="POST">';
for ($x = 0; $x <= 10; $x++) {
    $name = "type[$x]";
echo'<input type="submit" name="'.$name.'" value="'.$name.'" > <br/>';
}
echo'</form>';

He said he's already doing that, but it's difficult for many different names. – Barmar Jun 14 '21 at 18:01
I am trying to avoid this, like typing for each submit button. – user16225210 Jun 14 '21 at 18:07

Since only one submit button can be submitted, just use the same name for them all and whatever distinct value you want:

<form method="POST">
    <input type="submit" name="type" value="type1" > <br/>
    <input type="submit" name="type" value="type2" >
</form>

<?php
        
  if(isset($_POST["type"])){
    $_SESSION["value"] = $_POST["type"];
    header('Location:somepage.php');
  }

So $_SESSION["value"] will equal type1 or type2 based on the submit button value in this scenario.

This actually worked out!! – user16225210 Jun 14 '21 at 18:14
Thanks a lot. I thought that I would need a loop for this but never thought that a simple array would solve my problem. Thanks again!! – user16225210 Jun 14 '21 at 18:15

Why use an array? Only one submit button can be submitted at a time. – Barmar Jun 14 '21 at 18:21
@Barmar I see what you're saying. Edited... I was going down a more complex path at first and then didn't change direction. – AbraCadaver Jun 14 '21 at 21:20
been there, done that. – Barmar Jun 15 '21 at 00:48
