how to get the value in a textbox????

[amalp]

for example, i have a textbox

'<input type=text name=test value=important>

how do i assign the value inside the text box to a PHP variable, $value?

i want to do this on only one page, meaning i don't need to click any submit button.

i was using the $POST and $GET syntax but i receive an error stating that "undefined variable". i think that the 2 couldn't be used if i want to access that textbox value within the same page.

pls. help me. what syntax should i use of is their a function that i can use???

thanks.......

You can't access the textbox value in the same page with PHP unless you submit the value to back to the same page ie <form method="POST" action="<?php echo($_SERVER['PHP_SELF']);?>">
PHP is a server side language and therefore you can do no processing on the client's side.

if (isset($_GET['important'])):
$testvalue = $_GET['important'];
else:
$testvalue = '';
endif;

// then in your form

echo '<input type="text" name="test" value="'. $testvalue .'">';
