suggestive auto search not working properly

Question

i'm using suggestive search in my site but somehow its not workign.i have a table named as customers :

id     customername      location
1       ram                delhi
2       monty             new delhi
3       sandeep            noida

now i want to auto-search in this table for name and location so here is my code for that:

<?php
include("config.php"); 
$term=$_GET["term"];

$query=mysql_query("SELECT * FROM customers where customername like '%".$term."%' or location like '%".$term."%'");
$json=array();

    while($customer=mysql_fetch_array($query)){
         $json[]=array(

                    'value'=> $customer["customername "],
                    'label'=>$customer["customername "]." - ".$customer["id"],
                    'value'=> $customer["location"],
                    'label'=>$customer["location"]." - ".$customer["location"],

                        );
    }

 echo json_encode($json);

?>

with the help of this query i'm not able to auto search for customername and location both at one time means if i want to search customer name then it should give customer name and if i put location in search field it should give location.currently its giving me the last value as mentioned in above code this time its only giving me location.

Answer 1

Just try this

<?php
include("config.php"); 
$term=$_GET["term"];
$query=mysql_query("SELECT * FROM customers where customername like '%".$term."%' or location like '%".$term."%'");
$json=array();
    while($customer=mysql_fetch_array($query)){
         $json[]=array(                   
                  $customer["id"]=>$customer["customername "]." - ".$customer["location"]); 
        } 
        echo json_encode($json);    
?>

Your array is not constructed properly. You have duplicate key names, so they will be overwritted.

Let's say you have:

$json[] = array(
    'value' => 'x',
    'label' => 'x-y',
    'value' => 'y',
    'label' => 'y-x'
);


var_dump($json);

The output is:

array (size=1)
  0 => 
    array (size=2)
      'value' => string 'y' (length=1)
      'label' => string 'y-x' (length=3)

Even [] in $json, doesn't automatically make you to have 0=>array(x,y),1=>array(y,x), you need to specify the keys.

Because I don't know how many rows the MySQL is returning, my example will be with static while loop:

$max=5; //max iterations
$i = 0; //first key
$k = $max+1; //second key
while ($i<=$max) {
    $json[$i] = array(
        'value' => 'x',
        'label' => 'x-y'
    );
    $json[$k] = array(
        'value' => 'y',
        'label' => 'y-x'
    );
    $i++;
    $k++;
}

ksort($json); //this line is only to return the array sorted by keys asc, not necessary, for the testing purpose
var_dump($json);

The second key $k should never be equal to $i, that's why I use the maximum $i can reach, to starting point of $k. Output:

array (size=12)
  0 => 
    array (size=2)
      'value' => string 'x' (length=1)
      'label' => string 'x-y' (length=3)
  1 => 
    array (size=2)
      'value' => string 'x' (length=1)
      'label' => string 'x-y' (length=3)
  2 => 
    array (size=2)
      'value' => string 'x' (length=1)
      'label' => string 'x-y' (length=3)
  3 => 
    array (size=2)
      'value' => string 'x' (length=1)
      'label' => string 'x-y' (length=3)
  4 => 
    array (size=2)
      'value' => string 'x' (length=1)
      'label' => string 'x-y' (length=3)
  5 => 
    array (size=2)
      'value' => string 'x' (length=1)
      'label' => string 'x-y' (length=3)
  6 => 
    array (size=2)
      'value' => string 'y' (length=1)
      'label' => string 'y-x' (length=3)
  7 => 
    array (size=2)
      'value' => string 'y' (length=1)
      'label' => string 'y-x' (length=3)
  8 => 
    array (size=2)
      'value' => string 'y' (length=1)
      'label' => string 'y-x' (length=3)
  9 => 
    array (size=2)
      'value' => string 'y' (length=1)
      'label' => string 'y-x' (length=3)
  10 => 
    array (size=2)
      'value' => string 'y' (length=1)
      'label' => string 'y-x' (length=3)
  11 => 
    array (size=2)
      'value' => string 'y' (length=1)
      'label' => string 'y-x' (length=3)
