HTML/PHP - default input value

Question

I have a post php form and a set of inputs:

1. Your Name
2. Your Last Name
3. My Name

Every input looks the same, only the names change

Answer 1

You could use my tiny library ValueResolver in this case, for example:

$default = ValueResolver::resolve(get_option('your_name'), '<whatever your default value is>');

and don't forget to use namespace use LapaLabs\ValueResolver\Resolver\ValueResolver;

There are also ability to typecasting, for example if your variable's value should be integer, so use this:

$id = ValueResolver::toInteger('6 apples', 1); // returns 6
$id = ValueResolver::toInteger('There are no apples', 1); // returns 1 (used default value)

Check the docs for more examples

Answer 2

you can change the get_option() function to be something like

function get_option($name) {
   $defaults = array(
      'fist_name' => 'Mike',
      'fist_name' => 'Wordpressor',
      'my_name' => 'Dunno'
   );
   // get the value from the $defaults array
   $val = $defaults[$name];

   // but if the same value has already been posted - replace the default one
   if (isset($_POST[$name])) {
      $val = $_POST[$name];
   }
   return $val;
}

Answer 3

Set some variable at start with the post variables.

like

$name_val = "";
if(isset($_POST["your_name"])
{
    $name_val = $_POST["your_name"];
}

<input type="text" name="your_name" value="<?= $name_val?>">

Answer 4

Since value is the default, just add a condition around your get_option-function, maybe something like this:

<input type="text" name="your_name" value="<?php $var = get_option('your_name'); if ($var == '') $var = 'your_default'; echo $var; ?>" />
