I have a FORM that should send the user ID to PHP, but PHP receives null.

HTML: (the <?=$individuo["ID"] is returning id correctly)

<form name="alterar" action="alterar.php" method="POST">
    input type="text" name="id" value=<?=$individuo["ID"]?>>
    <input type="submit" name="Editar" value="editar"> 
</form>

PHP:

 <?php 

        var_dump($_POST["ID"]);
    ?>
php

Forgot to put the echo and uses single quotes.

Put your code like this:

<form name="alterar" action="alterar.php" method="POST">
    <input type="text" name="id" value="<?php echo $individuo['ID'] ?>">
    <input type="submit" name="Editar" value="editar"> 
</form>

Hello,

Even the $_POST indices are Case Sensitives, i.e., the right name would be "ID"

<form name="alterar" action="alterar.php" method="POST">
<input type="text" name="ID" value=<?=$individuo["ID"]?>>
<input type="submit" name="Editar" value="editar"> 
</form>

Or Change php this way:

<?php 

    var_dump($_POST["id"]);
?>

  • I’m impressed with, no matter how long you program, the problem will always be something silly like this. You saved my night, thank you very much.
