Hi im having a little trouble with pagination its not letting me use this username verification as well as the forum?
Any help would be appreciated!

<? if(!session_is_registered("username")){
echo "<p>&nbsp;</p>
<form name='login' method='post' action='register.php'>
<table border='0' width='400' align='center'>
<tr>
<td width='90'>Username:</td>
<td width='300'><input type='text' name='username' /></td>
</tr>
<tr>
<td width='90'>Password:</td>
<td width='300'><input type='password' name='password' /></td>
</tr>
<tr>
<td width='90'>Email:</td>
<td width='300'><input type='text' name='email' maxlength='100' /></td>
</tr>
<tr>
<td>Gender: </td><td><input name='gender' type='radio' value='male' /> Male
<input name='gender' type='radio' value='female' /> Female</td></tr>
<tr>
<td width='90'>&nbsp;</td>
<td width='300'>
<p align='left'><input type='submit' name='submit' value='Submit'></p> </td>
</tr>
</table>
</form>";

}else{

include 'connect.php';

// find out how many rows are in the table
$sql = "SELECT COUNT(*) FROM newtopic";
$result = mysql_query($sql) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
// cast var as int
$currentpage = (int) $_GET['currentpage'];
} else {
// default page num
$currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
// set current page to last page
$currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
// set current page to first page
$currentpage = 1;
} // end if

// the offset of the list, based on current page
$offset = ($currentpage - 1) * $rowsperpage;

// get the info from the db
$sql = "SELECT * FROM newtopic LIMIT $offset, $rowsperpage";
$result = mysql_query($sql) or trigger_error("SQL", E_USER_ERROR);

echo "<table width='371' border='0' align='center'>
<tr>
<td height='50' colspan='2'><b>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Fight Talk </b><input name='forumtype' type='hidden' value='fighttalk' /></td>
</tr>
<tr>
<td width='160' height='50' align='center' colspan='2'><a href='fighttalknewtopic.php'># New Topic</a></td>
</tr>
<tr>
<td><b>Username:</b></td><td><b>Message:</b></td>
</tr>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . " <b> " . $row['username'] . "</b><br />" . $row['date'] . " : " . $row['time'] . "</td>";;
echo "</td>";
echo "<td>" . $row['title'] . "</td>";
echo "</tr><tr>";
echo "<td colspan='2'>" . $row['message'] . "</td>";
echo "</tr>";
}
echo "</table>";

/****** build the pagination links ******/
// range of num links to show
$range = 3;

// if not on page 1, don't show back links
if ($currentpage > 1) {
// show << link to go back to page 1
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'>First</a> ";
// get previous page num
$prevpage = $currentpage - 1;
echo " - ";
// show < link to go back to 1 page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'>Previous</a> ";
} // end if

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
// if we're on current page...
if ($x == $currentpage) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
} // end else
} // end if
} // end for

// if not on last page, show forward and last page links
if ($currentpage != $totalpages) {
// get next page
$nextpage = $currentpage + 1;
// echo forward link for next page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>Next</a> ";
echo " - ";
// echo forward link for lastpage
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>Last</a> ";
} // end if
/****** end build pagination links ******/
?>

Sorry about the long code but this is the part it errors with:

<? if(!session_is_registered("username")){
echo "<p>&nbsp;</p>
<form name='login' method='post' action='register.php'>
<table border='0' width='400' align='center'>
<tr>
<td width='90'>Username:</td>
<td width='300'><input type='text' name='username' /></td>
</tr>
<tr>
<td width='90'>Password:</td>
<td width='300'><input type='password' name='password' /></td>
</tr>
<tr>
<td width='90'>Email:</td>
<td width='300'><input type='text' name='email' maxlength='100' /></td>
</tr>
<tr>
<td>Gender: </td><td><input name='gender' type='radio' value='male' /> Male
<input name='gender' type='radio' value='female' /> Female</td></tr>
<tr>
<td width='90'>&nbsp;</td>
<td width='300'>
<p align='left'><input type='submit' name='submit' value='Submit'></p> </td>
</tr>
</table>
</form>";

}else{

Also does anyone know how I can center the the "First - Previous 1-2-3-4 Next - Last" part of the pagination script?
Thanks for the help

I don't quite understand what the problem is :)

As for your question about centering the pagination links, simply add them in a div tag and user align: center inside a stylesheet.

The code pasted, is that all on one page?

You probably forgot to close the 'else' loops' bracket when you finish the script.

Code: Select all

//
</form>";

}else{

include 'connect.php';
//
Hint : Use the PHP Code button to wrap any php code in.
