How to create <form> for search with assoc array - php

Question

Hello can u help me with a script that i have trouble with ;\ i want to create a search script from different columns and price range: so the search.php is that:
<?php
/* connect to the database*/
$db = new mysqli("localhost", "root", "", "movie");
/* check connection */
if ($db->connect_errno) {
echo "Connection failed: " . $db->connect_error;
exit();
}
$query="SELECT * FROM `filmi`
WHERE (`nomer` rlike '%$search%' OR
`rezume` rlike '%$search%' OR
`kategoriq` rlike '%$search%') AND
`seriq` BETWEEN '%$pricemin%' AND '$pricemax'
ORDER BY seriq ASC";
/* create a prepared statement */
if ($stmt = $db->prepare($query)) {
/* bind parameters for markers */
$stmt->bind_param("sssdd", $search, $search, $search, $pricemin, $pricemax);
/* execute query */
$stmt->execute();
/* get result */
$result = $stmt->get_result();
if ($result) {
/* now you can fetch the results into an assoc array */
while ($row = $result->fetch_assoc()) {
echo $row['nomer']. ", " .$row['rezume']. ", " .$row['kategoriq']. ", " .$row['seriq']. "<br>";
}
}
/* close statement */
$stmt->close();
}
/* close db connection */
$db->close();
?>
What shoud be the "<form method=?>" form fill the $search and $pricemin / $pricemax fields ?

Answer 1

Check whether $search exists or not. Means, does there is some value in $search or not.
if(isset($search) && $search!=''){
case 1
}
else{
case 2
}
Case 1:
If there is value in $search then include it in where clause.
below query is an example to explain my idea.
$query="SELECT * FROM `filmi`
WHERE (`nomer` rlike '%$search%' OR
`rezume` rlike '%$search%' OR
`kategoriq` rlike '%$search%') AND
`seriq` BETWEEN '%$pricemin%' AND '$pricemax'
ORDER BY seriq ASC";
Case 2:
If there is no value in $search then does not include it in where clause.
check below query
$query="SELECT * FROM `filmi`
WHERE `seriq` BETWEEN '%$pricemin%' AND '$pricemax'
ORDER BY seriq ASC";

You can use either GET or POST method in your <form> tagg
and
in your PHP script you can use $form_var_name = $_REQUEST['form_var_name'] to access the data dispatched by form. To be more specific as follows
$search = $_REQUEST['search'];
$pricemin = $_REQUEST['pricemin'];
$pricemax = $_REQUEST['pricemax'];
