numbering an output in order - php

Question

i have made a image slider(or what ever you want to call it) and it displays the 6 latest images. Under the current bigger image you have all 6 of the most recent images , and the process works all fine but when you click the smaller image, it doesn't bring up the big image straight away. Because the very latest image is first its 'active' and has its own <a href="#1> and so the href="#1" is entered as i can manipulate the a tag as it is there. But as i used a foreach to bring up the next 5 images from 2nd to 6th in descending order from date submitted, i cant give each individual result there own href"#number" so they can link up with the bigger images, is there a way to assign each result a number by taking what position it sits within the query then adding 1or2 to the answer which would then give the corresponding number in the href so when clicked, the larger image which is linked to the href number too, it will make the larger image appear straight away.
the code from the tutorial that i have amended looks like this ..
<?php
$latest_headlines = get_latest_headlines();
foreach ($latest_headlines as $latest_headline) {
?>
<img src="img/<?php echo $latest_headline['img_title'].'.'.$latest_headline['img_ext']; ?>" class="nav-thumb" alt="<?php echo $latest_headline['title']; ?>" />
<?php
}
?>
<div id="movers-row">
<?php
$recent_headlines = get_recent_headlines();
foreach ($recent_headlines as $recent_headline) {
?>
<div><img src="img/<?php echo $recent_headline['img_title'].'.'.$recent_headline['img_ext']; ?>" class="nav-thumb" alt="<?php echo $recent_headline['title']; ?>" /></div>
<?php
}
?>
</div>
And here are my two functions to get the results, and before people start picking at all the problems ive done, just want to say this is the way ive learnt it im new, it maybe all wrong but its what stuck in my head to do things this way and its worked(ish) so far....
function get_recent_headlines() {
$sql = "SELECT *
FROM `story`
ORDER BY `submit_date` DESC
LIMIT 1, 5 ";
$result = mysql_query($sql) or die(mysql_error());
$recent_headlines = array();
while (($row = mysql_fetch_array($result)) !== false) {
$recent_headlines[] = array(
'title' => $row['title'],
'img_title' => $row['img_title'],
'img_ext' => $row['image_ext']
);
}
return $recent_headlines;
}
function get_latest_headlines() {
$sql = "SELECT *
FROM `story`
ORDER BY `submit_date` DESC
LIMIT 1 ";
$result = mysql_query($sql) or die(mysql_error());
$lastest_headlines = array();
while (($row = mysql_fetch_array($result)) !== false) {
$latest_headlines[] = array(
'title' => $row['title'],
'img_title' => $row['img_title'],
'img_ext' => $row['image_ext']
);
}
return $latest_headlines;
}

Answer 1

change your query of your function get_recent_headlines()
it uses a variable, and increment it in the SELECT statement:
`$sql = "SELECT *,(#row:=#row+1) AS rowno
FROM `story` inner join (SELECT #row:=0) AS row_count
ORDER BY `submit_date` DESC
LIMIT 1, 5 ";`

Answer 2

You can use a user variable to get a sequence number within MySQL.:-
SELECT Sub1.*,#aCount:=#aCount+1 AS aSequence
FROM (SELECT *
FROM `story`
ORDER BY `submit_date` DESC) Sub1
CROSS JOIN (SELECT #aCount := 0) Sub2
LIMIT 1, 5
