Laravel sql query is giving error while calling from ajax - php

Question

I have reg_dental_camp table having columns id, reg_name, reg_email, reg_phone, reg_type, reg_info, created_at, updated_at
I want to fetch the table data in Laravel and show them using ajax.
The function I have written is:
public function showUsers(){
$table ="SELECT * FROM `reg_dental_camp`";
$primaryKey = 'id';
$userColumns = array(
array( 'db' => 'id', 'dt' => 'id' ),
array( 'db' => 'reg_name', 'dt' => 'reg_name' ),
array( 'db' => 'reg_email', 'dt' => 'reg_email' ),
array( 'db' => 'reg_phone', 'dt' => 'reg_phone' ),
array( 'db' => 'reg_type', 'dt' => 'reg_type' ),
array( 'db' => 'reg_info', 'dt' => 'reg_info' ),
array(
'db' => 'created_at',
'dt' => 'created_at',
'formatter' => function( $d, $row ) {
return date( 'jS M y', strtotime($d));
}
)
);
if($_SERVER['HTTP_HOST']=='localhost'){
$sql_details = array(
'user' => 'root',
'pass' => '',
'db' => 'ubl',
'host' => 'localhost'
);
}
$userResult = SSP::simple( $_GET, $sql_details, $table, $primaryKey, $userColumns);
print_r($userResult);
}
While visiting from the main page it is showing error number 500 on ajax call URL and visiting directly to the ajax call URL is is giving SQL error SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'SELECT * FROM `reg_dental_camp`
How can I solve this problem? Thanks in advance

Answer 1

Your are using simple method wrongly
Simple implementation from GitHub
static function simple ( $request, $conn, $table, $primaryKey, $columns )
{
$bindings = array();
$db = self::db( $conn );
// Build the SQL query string from the request
$limit = self::limit( $request, $columns );
$order = self::order( $request, $columns );
$where = self::filter( $request, $columns, $bindings );
// Main query to actually get the data
$data = self::sql_exec( $db, $bindings,
"SELECT `".implode("`, `", self::pluck($columns, 'db'))."`
FROM `$table`
$where
$order
$limit"
);
// Data set length after filtering
$resFilterLength = self::sql_exec( $db, $bindings,
"SELECT COUNT(`{$primaryKey}`)
FROM `$table`
$where"
);
$recordsFiltered = $resFilterLength[0][0];
// Total data set length
$resTotalLength = self::sql_exec( $db,
"SELECT COUNT(`{$primaryKey}`)
FROM `$table`"
);
$recordsTotal = $resTotalLength[0][0];
/*
* Output
*/
return array(
"draw" => isset ( $request['draw'] ) ?
intval( $request['draw'] ) :
0,
"recordsTotal" => intval( $recordsTotal ),
"recordsFiltered" => intval( $recordsFiltered ),
"data" => self::data_output( $columns, $data )
);
}
So you need to provide table name only not a query. Change table variable to
$table = "reg_dental_camp"
