[RESOLVED] recover text area from form

thosecars82

Is there any way to recover the current content of a text area from a form without using javascript, just with php?

You mean.. when the form is submitted? You cannot do it without submitting the form, as PhP runs on the server, and is unaware of changes that the client makes, untill the client talks to the server again

You use the $GET or $POST array (depending on the action type) and retrieve through the textarea name;

$content = $_POST['TEXTAREANAME'];

Sorry leatherback, if you are administrator, you can join this thread with the other one.
Anyways, what you tell ("cannot do it without submitting the form, as PhP runs on the server")me seems quite reasonable. Nevertheless, I would like to know how to send information from several forms on the same page with the post method. Is there anyway to do this? That is to say, to send with post but not only the information of one form, but the information of let's say any number of forms you might want all of them at the same click.

sorry, not an administrator.

hm.. Why not just have one form on the page?

In any case.. If you want to keep multiple forms, you will need to write some javascript, I am afraid.

Having heard that ("If you want to keep multiple forms, you will need to write some javascript") and considering it is true I think this post is solved. The only possible alternative which might come to my mind would be to use just one form with absolute positioned elements all of them far away from each other. Nevertheless, I do not think using such a lot of absolute positioned elements make a good design. For that reason, I consider using javascript the best choice.
Thanks all of you again.

What I meant was this:
Let's say I want to link another page without losing the content of 5 text areas each of them in different forms I might have in my page. Then if I click the submit button of one of the forms, this would link to another page. Nonetheless, I would not want to lose the content of the 4 text areas which are on the other 4 forms different from the one whose button I clicked. How can I keep the content of all the text areas if they are in different forms? That was my question.

Now another question:
now I am trying to read the content of a text area whose id is idcomentarios to be able to send it by post method to the server. The code is this:

...
<?php
$state = "?send=0";
if (isset($GET['send']))
$state = "send=" . $GET['send'];

if ($language=='en')
{

echo '<FORM id=\'intermedio\' action=\''.$pagina.'?' . $state.'&language=sp'.'\' method=\'post\'>';
echo '<P>';
echo '<INPUT class = \'enlacespanishflag\' type=\'submit\' value=\'';
echo _(" ") . "'>";
echo '<TEXTAREA id=\'comentariosintermedios\' rows=\'10\' cols=\'10\'>';
?>
<script type="text/javascript">


</script>

<?php
echo '</TEXTAREA>';
echo '</P>';
echo '</FORM>';

....

Now, what I see in the text area with id comentariosintermedios is just this:
<script type="text/javascript">


</script>

Nevertheless, what I expected to see was what actually the user might have written in the content of the text area with id 'idcomentarios'. Any idea to get the real content of the text area?
