hey guys....I have included my whole script below....what im trying to do is show 5 results per page. Ive created a function to display a table with information from my database. I have it so either a) it works but displays all the results from my database on the page or b) the pagination works, displays 5 results per page, however it only shows the last record in my database. I have included the full code, but will highlight the part that I think is causing the problem. Any help is much appreciated. Thanks in advance

<?php

// Define db details

$tbl_name="prospects"; //your table name

// How many adjacent pages should be shown on each side?

$adjacents = 3;

 

/*

  First get total number of rows in data table.

  If you have a WHERE clause in your query, make sure you mirror it here.

*/

$query = "SELECT COUNT(*) as num FROM $tbl_name";

$total_pages = mysql_fetch_array(mysql_query($query));

$total_pages = $total_pages[num];

 

/* Setup vars for query. */

$targetpage = "view_prospect.php"; //your file name  (the name of this file)

$limit = 5; //how many items to show per page

$page = $_GET['page'];

if($page)

$start = ($page - 1) * $limit; //first item to display on this page

else

$start = 0; //if no page var is given, set start to 0

 

/* Get data. */

$sql = "SELECT prospect_id FROM $tbl_name LIMIT $start, $limit";

$result = mysql_query($sql);

 

/* Setup page vars for display. */

if ($page == 0) $page = 1; //if no page var is given, default to 1.

also, since I posted the whole code I might as well as my 2nd question that I will have once this problem gets fixed - as you can see I have my table which shows different info per row - I want it so that every 2nd row the table has a different color bg so its easy on the eyes - how is this accomplished?? thanks again

Wrong reference

 

Change the highlighted section to:

// Get all news entries
$prospectEntries = mysql_query('SELECT * FROM prospects ORDER BY prospect_id DESC') or trigger_error(mysql_error());
while ($prospectEntry = mysql_fetch_array($prospectEntries))
{
//print_prospectEntry($prospectEntry);    when printing here it prints all the records

	while($row = mysql_fetch_array($result))
	{

	// Your while loop here

	print_prospectEntry($row['prospect_id']); // when printing here, it does 5 results per page like I want, however it just prints the same record
	//echo $row;
	}
}

I had the concept backwards when I looked at it first.

 

Instead of a nestled loop try just changing the highlighted to:

 

// Get all news entries
$prospectEntries = mysql_query('SELECT * FROM prospects ORDER BY prospect_id DESC LIMIT $start, $limit') or trigger_error(mysql_error());
while ($prospectEntry = mysql_fetch_array($prospectEntries))
{
print_prospectEntry($prospectEntry);
}

 

 

Sorry I had a brain fart earlier.

Andrew:

 

when trying your code I get the following errors

 

Notice: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '$start, $limit' at line 1 in /home/content/view_prospect.php on line 198

 

aswell as

 

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/content/view_prospect.php on line 199

 

where as line 198 and 199 are as follows

 

$prospectEntries = mysql_query('SELECT * FROM prospects ORDER BY prospect_id DESC LIMIT $start, $limit') or trigger_error(mysql_error());
while ($prospectEntry = mysql_fetch_array($prospectEntries))

perfect! you fixed my problem with the pages! However for the color thing what I was thinking of I want the whole table for the first record to be 1 color, then the next time it displays for the next record to be a different color. Not the rows. How do I accomplish this?

 

Thanks in advance
