Answer 1

you have inserted wrong syntax ....use this
$strSQL = "SELECT * FROM category WHERE name LIKE '%$name'";

Answer 2

You need to open a connection to your database. Something like:
<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
$name=$_GET['name'];
$strSQL = "SELECT * FROM category WHERE name LIKE '%" .$name . "%'";
// $strSQL = "SELECT * FROM category WHERE name = '" .$name . "'";
$rs = mysql_query($strSQL, $conn);
// Loop the recordset $rs
$response = array();
while($row = mysql_fetch_array($rs)) {
$product = array();
$product["id"] = $row["id"];
$product["name"] = $row["name"];
array_push($response, $product);
}
echo json_encode($response);
?>
Also if you are going to use "LIKE" in your sql, you don't use "=".

Answer 3

It is because You are not sending Query matched with your datatype of the name field.
Try below syntax with ''
$strSQL = "SELECT * FROM category WHERE name LIKE '" .$name . "'";
IF you still getting the same error then try this code
$name=$_GET['name'];
$strSQL = "SELECT * FROM category WHERE name LIKE '" .$name . "'";
$rs = mysql_query($strSQL);
if(mysql_num_rows($rs) > 0){
// Loop the recordset $rs
$response = array();
while($row = mysql_fetch_array($rs)) {
$product = array();
$product["id"] = $row["id"];
$product["name"] = $row["name"];
array_push($response, $product);
}
echo json_encode($response);
}
}
else{ echo json_encode(array('msg'=>"No records found")); }
