How to receive HTML form name in php after submiting HTML form

Question

I have this code in HTML:

 <input type ="text" name="<?php echo $id_global;?>"</input>

Then after submitting the form, I am trying something like this, but it's not working:

$id_s = $_POST['$id_global'];

You can't do this because when you submit your form, the name will be something you don't know. It's $_POST something. You can do print_r($_POST); to find it — Hearner

You need to remove the quotes,

try $id_s=$_POST[$id_global];

Then we will need more context around your code, because that is the only error we can see right now.

@zeeshansarfraz does this $id_global variable still contain a value after you have posted?

Try with double quotes php will not consider variable between single quotes and try with this also :

<?php 
    $id_global = 'field_name';
?>
<form action="/Stackoverflow/index.php" name="testForm" method="POST">
    <input type ="text" name="<?php echo $id_global;?>" />
</form>

<?php 
if($_POST){
    echo '<pre>';
    print_r($_POST[$id_global]);
}
?>

Edit the action as per your need
