Displaying $_POST values in text boxes

RiceRocket

Ok, i'm just trying to display a value in $_POST to a html text box

how do I go about doing this?

I have something like

<?php

if($POST["submit"])
{
//post the value of $POST["example"] to a text box
}

<form name="somename" action="www.somesite.com/page.php" method="post">
<input type="text" name="boxname" value="<?
if(isset($_POST["value"] && $_POST["vaulue"]="") {
  echo($_POST["value"];
}
?>">
</form>

Hope this helps

I would recommend:

<input type="text" name="fieldname" value="<?php
if (isset($_POST['fieldname']))
	echo htmlspecialchars($_POST['fieldname']);
?>" />

<input type="text" name="fieldname"<?php
if (isset($_POST['fieldname']) && $_POST['fieldname'] != NULL)
	echo htmlspecialchars($_POST['fieldname']);
?> />

Instead of comparing with NULL one could also check that strlen() returns a value greater than 0.
If magic quotes are on for POST operations, you should use:

echo htmlspecialchars(stripslashes($_POST['fieldname']));

Note that you wont need a name for the form (in the form tag), and that if you are using the same page to process the form, you can set the action to $_SERVER['PHP_SELF']
The method should of course be post.
Also, you might want to note that setting the action to "www.somesite.com/page.php" as given by OhLordly probably wouldnt work, you should either set using the absolute path with "http://" included, or using a relative path like with "./page.php"
