PREVIOUS and NEXT

[The Little Guy]

How would you do PREVIOUS, and NEXT links from an array using the keys of the array?

When there are no more keys in the array, the next link will say First.

When there are no previous keys in the array, the prev link will say Last.

 

I don't know if my brain is dead, or I just don't know, but I cannot get this.

What kind of array are you talking about, single level, multidimensional or sql array??

[The Little Guy]

if I do a print_r... I get this:

Array ( [0] => 5 [1] => 3 [2] => 1 [3] => 2 [4] => 4 )

 

It was generated from my SQL.

try sort($array_name);

[The Little Guy]

its already sorted the way I want it to be sorted.

<?php

$pagein = $_GET["pagein"];
$rowmax = "20";
if(!isset($pagein)) { 
          $pagein = 0; 
 }

  $query = "SELECT * FROM table WHERE text LIKE '%$searchterm%' OR coding LIKE '%$searchterm%'   LIMIT  $pagein, $rowmax";

$num_rows = mysql_num_rows($query);

 if(isset($pagein)) { $read2 = $pagein-$rowmax; }

 if($pagein > 0) {
 	$resultsin = $pagein;
echo "<a href='index.php?searchterm=$searchterm&pagein=$read2'>« Prev 20 Results</a> ";
}
 $read = $pagein+$rowmax;
 
if($num_rows > $pagein+$rowmax) {
$resultsout =  $pagein+$rowmax;
}
if($num_rows < $pagein+$rowmax) {
$resultsout =  $num_rows;
}
if($num_rows > ($pagein+$rowmax)) {
$f = ($num_rows - ($pagein+$rowmax));
if($f < $rowmax) {
$fy = $f;	
}

if($f > $rowmax) {
$fy = "20";	
}
//  if($pagein > 1) {
//	$resultsin = $pagein;
//}
 if($pagein == 0) {
$resultsin = "1";
}
if(($pagein > 0) & ($num_rows > $pagein+$rowmax)) {
echo"&#124; ";

}
echo "<a href='index.php?searchterm=$searchterm&pagein=$read'>Next $fy Results &raquo</a><br />";
} 

?>

There!!! I think it works now!!!

 

Here is the code I used:

 

after I made my SQL:

<?php
while($garray = mysql_fetch_array($girls)){
$gid .= $garray['id'];
}
$g = str_split($gid);
print_r($g);
$key = array_search($id,$g);
$mode = current($g);
for($i=0;$i<$key;$i++){
$mode = next($g);
}
$mode = prev($g);
if($mode == ""){
$mode = end($g);
}
echo '<a href="next.php?id='.$mode.'">Previous</a>';
$mode = reset($g);
for($i=0;$i<$key;$i++){
$mode = next($g);
}
$mode = next($g);
if($mode == ""){
$mode = reset($g);
}
echo '<a href="next.php?id='.$mode.'">Next</a>';
?>
