To post a hidden text value in an HTML form, you can use an input element with a type of “hidden”. Here’s an example:
<form action="submit.php" method="post"> <input type="hidden" name="hiddenField" value="Hidden value here"> <button type="submit">Submit</button> </form>
In this example, we’ve added an input element with a type of “hidden” and given it a name of “hiddenField”. We’ve also set the value of the input element to “Hidden value here”. When the form is submitted, the value of the hidden field will be sent to the server along with the values of any other form fields.
In your server-side script (e.g. “submit.php” in this example), you can access the value of the hidden field using the $_POST superglobal array in PHP. For example:
$hiddenValue = $_POST['hiddenField'];
This will retrieve the value of the hidden field and assign it to the variable $hiddenValue. You can then use this value in your PHP code as needed.
