Hi, I have been trying to get the below code to work but without luck for the past couple of days.

Can anyone help point out where i am going wrong.

I have a webpage that has several buttons which will eventually let users search for data stored in different tables of a postgresql database ( i have simplified the code here to just two buttons).

When the user clicks the Search for hostname button a form is displayed letting them type in their search criteria.

Upon clicking the submit button i am able to access the users search strings with no problem but i cannot get the original search form to display above the search results additonaly including the users original search strings.

Any help on this would be much appreciated as i am pulling my hair out, as you can probably guess i am very new to PHP/HTML

My code is


<? 
session_start(); 
?>

<form method="POST" action="<? echo $_SERVER['PHP_SELF'];?>">
<center>
<button type="submit" id="green_button" name="searchhostname">Search for Hostname</button>
<button type="submit" id="green_button" name="searchipaddress">Search for IP address</button>
</center>
</form>
</body>




<?
// If user clicks the search hostname button display the additonal search form
if ($_POST['searchhostname'])
{
echo "Search for Hostnames and IP Addresses:<br><br>";
echo "<form method='POST' action='".$_SERVER['PHP_SELF']."'>";
echo "Hostname: <input type='text' name='hostname' size='16' value='".$_POST['hostname']."'/>";
echo "<br>";   
echo "Operating System: <input type='text' name='ostype' size='16' value='".$_POST['ostype']."'/>";
echo "<br>";
echo "<input type='submit' id='green_button' value='Search' name='runsearch'><br><br>";
echo"</form>";


}

// If user has entered criteria to search on run the search but alos display the original search form above
// and any data the user has entered before displaying results

if ($_POST['runsearch'])
{
//In reality this is where the users search data will be compared to a postresql database....

echo "You want to search for hostname: ".$_POST['hostname']."<br>";
echo "You want to search for operating system: ".$_POST['ostype']."<br>";
}


?>

Hi all,

Not sure if this is a browser feature kind of thing, or if it can be done with a script.

I'm looking at my page:
www.mysite.com/index.php?start=0

I scroll to the bottom of the page with the vertical scroll bar, and then click the pagation link to start on page 2, record #50:
www.mysite.com/index.php?start=50

Of course, the vertical scroll bar jumps back to the it jumps to the top of my page.

Is there a way to make it remember that the scroll bar was at the bottom (or in the middle)?

Thanks.

After inputing my email and password  and clicking submit, the echo in Verify_User (in bold) doesn't show up, nor does it load the logged in form of the log in bar.  If I reload the page or press submit again (even without entering any information), everything works.  At first I though I might just be outputting before getting my input on the reload, but all info is obtained at the top.  I also thought it might be $logoff, but it doesn't tell me "You logged off!", while still setting $logoff to true by the end in order to output the login menu.  Therefore, it get's passed if($Logoff) but doesn't make it to Verify_user, so for some reason $L_Email and $L_Password aren't set after the first refresh.  I'm a newbie so any help, related to the problem or not, would be greatly appreciated.
P.S.  The logoff button works the first time.


Code: [Select]
<?php
$L_Email = $_POST['l_email'];
