Is there a way to set a $_POST['var']
without using form related field (no type='hidden') and using only PHP. Something like
$_POST['name'] = "Denniss";
Is there a way to do this?
EDIT: Someone asked me for some elaboration on this. So for example, I have page with a form on it, The form looks something like this
<form method='post' action='next.php'> <input type='text' name='text' value='' /> <input type='submit' name='submit' value='Submit'/> </form>
Once the submit button is clicked, I want to get redirected to next.php. Is there a way for me to set the $_POST['text'] variable to another value? How do I make this persistent so that when I click on another submit button (for example) the $_POST['text'] will be what I set on next.php without using a hidden field.
Let me know if this is still not clear and thank you for your help.
PHP $_POST is a PHP super global variable which is used to collect form data after submitting an HTML form with method="post".
$_POST is a superglobal whereas $POST appears to be somebody forgetting the underscore. It could also be a standard variable but more than likely it's a mistake.
$_POST is a predefined variable which is an associative array of key-value pairs passed to a URL by HTTP POST method that uses URLEncoded or multipart/form-data content-type in request.
Yes, simply set it to another value:
$_POST['text'] = 'another value';
This will override the previous value corresponding to text
key of the array. The $_POST
is superglobal associative array and you can change the values like a normal PHP array.
Caution: This change is only visible within the same PHP execution scope. Once the execution is complete and the page has loaded, the $_POST
array is cleared. A new form submission will generate a new $_POST
array.
If you want to persist the value across form submissions, you will need to put it in the form as an input
tag's value
attribute or retrieve it from a data store.
