Thanks for responding Sam! So I’m currently trying to update the field with text input from a key and value input text box when a submit button is being pressed in an admin menu page. The field I’m trying to update is a text area. Here is the code:
<form action="" method="POST">
<input type="text" name="key" id="key">
<input type="text" name="value" id="value">
<input type="submit" name="Submit" value="send" >
</form>
<?php
if(isset($_POST['Submit']))
{
$key = $_POST["key"];
$value = $_POST["value"];
$array = array($key,array($value));
$out = json_encode($array);
update_field('field_key',$out);
}
?>
