How to show next and prev records

Posted on 16th Feb 2014 by admin

Hi all,

Sorry if this is simple, i'm very new to php, well, any programming language actually.

My code runs a query and comes back with the results. Very rarely there may be more than one result.

I have added the code that I think should enable me to go to the next and previous records but it is not working. I have tried lots of different bits of code so now its all over the shop!

Can you help please?

Jamie
Code: [Select]<?php
//run ext query
require("conf.php");
{
$udf_form = $_POST['udf'];

$extract = mysql_query ("SELECT * FROM cy_equ WHERE udf = '$udf_form' LIMIT 1 ");
$numrows = mysql_num_rows ($extract);

while ($row = mysql_fetch_assoc($extract))
{
$id = $row['id'];
$equ = $row['equ'];
$ext = $row['ext'];
$udf = $row['udf'];
$udf2 = $row['udf2'];
$udf3 = $row['udf3'];

$next = $udf + 1;
$prev = $udf - 1;

}

}

$next = $udf_form + 1;
$prev = $udf_form - 1;



?>

<div class="boxextqry">
<h3> UDF Query </h3>
<form name="form1" method="post" action="../index1.php?page=udfsearch">
<p> Input UDF: <input type="number" name="udf" size="1" maxlength="4"/></p>


<p> ID = <font color="red"><?php echo $id; ?> </font> </p>
<p> EXT = <font color="red"><?php echo $ext; ?> </font> </p>
<p> EQU = <font color="red"><?php echo $equ; ?> </font></p>
<p> UDF = <font color="red"><?php echo $udf; ?> </font></p>
<p> UDF2 = <font color="red"><?php echo $udf2; ?> </font></p>
<p> UDF3 = <font color="red"><?php echo $udf3; ?> </font></p>

<p><input type="submit" name="submit" value="GET DATA"/></p>
<p><input type="submit" name="udf[<?php echo $next?>]" value="NEXT"/></p>
<p><input type="submit" name="udf[<?php echo $prev?>]" value="PREV"/></p>

</form>

</div>
