How can explode a words from field with multiple values? - php

Question

I have this table: TABLE_ELEMENTS, with the name ELEMENTS, i have a multiple values inside, see image.
This is the php and return the results from autocomplete request.
$("#autocomplete").autocomplete({
source: "http://localhost/include/autocomplete.php?type=mauto_complete",
First i call this..
if(isset($_GET['type']) && in_array($_GET['type'], $arr_action)) $type=$_GET['type'];
if($type == "mauto_complete") {
require_once $config_abs_path."/autocomplete/autocomplete.php";
if(isset($_GET['term'])) {
$term = escape($_GET['term']);
$response = mauto_complete::getAutocomplete($term);
echo json_encode($response);
}
}
And this is the secondauto.php file
function getAutocomplete($term) {
global $db;
global $config_table_prefix;
global $crt_lang;
$elements=$db->fetchRow("select Distinct `elements` from TABLE_ELEMENTS where `elements` like '$term%' limit 10");
$elements_array = explode("|", $elements);
return $elements_array;
}
I have write this after select
$elements_array = explode("|", $elements);
Ok the request is working fine, but in autocomplete results when i type the word Building i take no words.
But when i type the first word of the elements ( Apartment ) i take all words.
The words is not uniqe

A common approach to this is to add a | to the left of the field, then search that. This ensures that an element containing the search doesn't get matched.
select
Distinct `elements`
from
TABLE_ELEMENTS
where
lower(CONCAT('|', `elements`)) LIKE lower('%|$term%')
However, you're probably looking for something else. Below is how I'd approach it. I couldn't figure out what library you were using for your connection, so you may have to change a little bit for it to work for you.
function getAutocomplete($name, $term)
{
// make sure you escape the string to avoid SQL injection
$name = mysqli_real_escape_string($db, $name);
// make the searches case-insensitive
$term = strtolower($term);
// fetch the valid elements for the field and split them using explode
$elements = $db->fetchRow("SELECT `elements` FROM `TABLE_ELEMENTS` WHERE `name` = '$name'");
$elements_array = explode('|', $elements);
// make an array to save the matching elements
$filtered = array();
// iterate over each element to check for a match
foreach($elements_array as $element)
{
// check to see if the beginning of the element starts with the search term
if(strpos(strtolower($element), $term) === 0)
{
// add it to the filtered array
$filtered[] = $element;
}
}
// return the matching results
return $filtered;
}
Then to use it, specify what field you want to autocomplete for:
print_r(getAutocomplete('Property Type', 'B'));
// Outputs: Array
// (
// [0] => Building
// [1] => Bungalow
// [2] => Business
// )
To make your existing code to use it, change your JavaScript to match the following. You'll need to change name depending on what field you're autocompleting.
$("#autocomplete").autocomplete({
source: "http://localhost/include/autocomplete.php?type=mauto_complete&name=Property%20Type"
});
Then update the file where you call the getAutocomplete function:
if(isset($_GET['type']) && in_array($_GET['type'], $arr_action)) $type=$_GET['type'];
if($type == "mauto_complete") {
require_once $config_abs_path."/autocomplete/autocomplete.php";
if(isset($_GET['term']) && isset($_GET['name'])) {
$name = $_GET['name'];
$term = $_GET['term'];
$response = mauto_complete::getAutocomplete($name, $term);
echo json_encode($response);
}
}

Try use like this to get all possible results
$elements=$db->fetchRow("select distinct `elements` from TABLE_ELEMENTS where lower(`elements`) like lower('%$term%') limit 10");
