this is a function to move items in an array up or down in the array. it is done by breaking the array into two separate arrays and then have a loop creates the final array adding the item we want to move when the counter is equal to the new position we established the array key, position and direction were passed via a query string <?php //parameters //$array- the array you are modifying //$keytomove - the key of the item you wish to move //$pos - the current position of the item: used a count($array) function //and then loop with incrementing integer to add the position to the up //or down button //$dir - the direction you want to move it - "up"/"dn" function change_pos($array, $keytomove, $pos, $dir){ //count the original number of rows $count = count($array); //set the integer we will use to place the moved item if($dir=="up"){ if($pos==1){ //if the item is already first and we try moving it up //we send it to the end of the array $change = $count; }else{ //anywhere else it just moves back one closer to the start of the array $change = $pos-1; } } //do the same for the down button if($dir=="dn"){ if($pos==$count){ $change = 1; }else{ $change = $pos+1; } } //copy the element that you wish to move $move = $array[$keytomove]; //delete the original from the main array unset($array[$keytomove]); //create an array of the names of the values we //are not moving $preint = 1; foreach($array as $c){ $notmoved["{$preint}"] = $c['name']; $preint++; } //loop through all the elements $int = 1; while($int<=$count){ //dynamically change the key of the unmoved item as we increment the counter $notmovedkey = $notmoved["$int"]; //when the counter is equal to the position we want //to place the moved entry we pump it into a new array if($int==$change){ $neworder["{$keytomove}"] = $move; } //add all the other array items if the position number is not met and //resume adding them once the moved item is written if($contkey!=""){ $neworder["{$notmovedkey}"] = $array["{$notmovedkey}"]; } $int++; } return($neworder); } ?> This is not too elegant but it works. --was-- //fixing errors in last post...oops //this is a function to move items in an array up or down //in the array. it is done by breaking the array into two //separate arrays and then have a loop creates the final array //adding the item we want to move when the counter is equal //to the new position we established //the array key, position and direction were passed via a query string //parameters //$array- the array you are modifying //$keytomove - the key of the item you wish to move //$pos - the current position of the item: used a count($array) function //and then loop with incrementing integer to add the position to the up //or down button //$dir - the direction you want to move it - "up"/"dn" function change_pos($array, $keytomove, $pos, $dir){ //count the original number of rows $count = count($array); //set the integer we will use to place the moved item if($dir=="up"){ if($pos==1){ //if the item is already first and we try moving it up //we send it to the end of the array $change = $count; }else{ //anywhere else it just moves back one closer to the start of the array $change = $pos-1; } } //do the same for the down button if($dir=="dn"){ if($pos==$count){ $change = 1; }else{ $change = $pos+1; } } //copy the element that you wish to move $move = $array[$keytomove]; //delete the original from the main array unset($array[$keytomove]); //create an array of the names of the values we //are not moving $preint = 1; foreach($array as $c){ $notmoved["{$preint}"] = $c['name']; $preint++; } //loop through all the elements $int = 1; while($int<=$count){ //dynamically change the key of the unmoved item as we increment the counter $notmovedkey = $notmoved["$int"]; //when the counter is equal to the position we want //to place the moved entry we pump it into a new array if($int==$change){ $neworder["{$keytomove}"] = $move; } //add all the other array items if the position number is not met and //resume adding them once the moved item is written if($contkey!=""){ $neworder["{$notmovedkey}"] = $array["{$notmovedkey}"]; } $int++; } return($neworder); } This is not too elegant but it works. http://php.net/manual/en/function.end.php
