using implode to insert values into database table columns - php

Question

I am using php implode to insert values, fetched from array of input fields, into a database table column. This works fine for me:
$insert_row =mysql_query("INSERT INTO ActivityProduct (Ideal) VALUES (" . implode('),(', $_POST["ideal"]) . ")");
I'd like to now insert values, fetched from two different array of input fields, into two database table columns. The below code produces and error:
$insert_row =mysql_query("INSERT INTO ActivityProduct (AID,Ideal) VALUES (" . implode('),(', $_POST["act"]) . " ," . implode('),(', $_POST["ideal"]) . ")");
i'd like to express the two arrays, in the insert statement, as, e.g: (10,21),(20,31),(30,41) and not (10),(21),(20),(31),(30),(41)
any idea on how to go about this, is highly appreciated.

Answer 1

Use like this it may help you
$ideal=implode('),(', $_POST["ideal"]);
$act=implode('),(', $_POST["act"]);
$insert_row =mysql_query("INSERT INTO ActivityProduct (Ideal) VALUES (" .mysql_real_escape_string($ideal). ")");
$insert_row =mysql_query("INSERT INTO ActivityProduct (AID,Ideal) VALUES (" .mysql_real_escape_string($ideal). " ," .mysql_real_escape_string($act). ")");
and try to use mysqli insted of mysql.
In mysqli
$insert_row = mysqli->prepare("INSERT INTO ActivityProduct (Ideal) VALUES ($ideal)");
$insert_row =mysql_query("INSERT INTO ActivityProduct (AID,Ideal) VALUES ($ideal,$act)");

Answer 2

replace this query with your query its work you
$insert_row =mysql_query("INSERT INTO ActivityProduct (AID,Ideal) VALUES ( '". implode('),(', $_POST["act"]). "' ,'" .implode('),(', $_POST["act"])."')");

Please note that the mysql_query extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.
Since a MySQLi example has been given consider if you were to use PDO.
// Build the parameter list
$sql = array(); $params = array();
for ($i=0; isset($_POST['ideal'][$i])&&isset($_POST['act'][$i]); $i++) {
$sql[] = ":act_{$i}, :ideal_{$i}";
$params["ideal_{$i}"] = $_POST['ideal'][$i];
$params["act_{$i}"] = $_POST['act'][$i];
}
// Then run the query safely using PDO
$dbh = new PDO('mysql:host=localhost;dbname=test', "user", "pass");
$stmt = $dbh->prepare("INSERT INTO ActivityProduct (AID, Ideal) VALUES (".implode("), (", $sql).")");
$result = $stmt->execute($params);
