Delete text in textbox using PHP

Question

Is there a way to remove text from a text field using the submit button?

I do not want to remove text from all form fields.

And I do not want to delete the text 'onclick' for the element.

I need code to clear a text box to start from within a block.

for instance

<input name="text" value="submit" />
<input type="sumbit"/>

<?php 
   if($_POST['submit'] == "submit")
{
  //clear text box with name "text"
}
?>

Thank you for your help!

Answer 1

You can do this in two ways:

• using onclick handler of submit button in javascript

• using php

  if (count ($ _ POST)> 0) {$ _REQUEST ['text'] = $ _GET ['text'] = $ _POST ['text'] = ''; }

Answer 2

onclick="document.getElementById('mytextbox').value = '';"
