hidden form field

[kusarigama]

Hi all,

is there a way to output hidden form fields on the first submit:
I need it to output error messages on the top of my script!


<form action=<?=$_SERVER['PHP_SELF'];?> method=post>

<input type=hidden name=collect value=<?=$_POST['collect']?>>

<?PHP
echo $_POST['collect'];
?>
<?
if(isset($_POST['submit']))
{
if($nomail == 1)
{
$_POST['collect'] = &quot;no mail sent&quot;;
}
}
?>

Thanx in advane

&quot;is there a way to output hidden form fields&quot; -> no, they are hidden. But you can un-hide them.
You question is not really clear to me. What exactly do you want to do ? Is that something like : there's a 1st post. If this post passes me a value for &quot;collect&quot;, fine, i go on. If not, i want to print an error ?
I think that if you can formulate your question very clearly, it'll be easier to answer for us, and you might even find yourself the answer.

OK i want to output the value of the &quot;hidden form field&quot;.
When I hit submit, the the value is put to the hidden form field. when I hit the submitbutton a second time the value of the hidden field is dispalyed. Is there a way to display the value on the first submit

i'm not sure php is the best way to go - you can keep it client side, using javascript, so there's no need to always submit the form to the server. But let's go with php :
&quot;Is there a way to display the value on the first submit&quot; :
<?php
if ($_POST['collect']) {echo $_POST['collect'] }
?>
<form action=<?=$_SERVER['PHP_SELF'];?> method=post>
<input type=hidden name=collect value=<?=$_POST['collect']?>>
</form>
wheter it's the 1st, the 2nd or the n-th submit, the value is displayed. if ($_POST['collect']) means : if the form was submitted and the value for collect was set ...
but i wonder why you use value=<?=$_POST['collect']?> in the hidden field ... how can this ever have any value ?
