How to show next and prev records

Posted on 16th Feb 2014 07:03 pm 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?

Code: [Select]<?php
//run ext query
$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>
