How to insert this full article? - php

Question

this PHP-line:
$xx_val = (string) $xx;
generate the following output:
string(16) "XYZ1"
string(11) "XYZ2"
string(12) "XZY1"
string(19) "XZY2"
string(34) "8997451"
when I insert it to my db:
$xx_val = (string) $xx;
$sql = "INSERT INTO attributes (article) VALUES ($xx_val)";
if ($conn->query($sql) === TRUE) {
echo "\n\n### DONE ###\n\n";}
else {
echo "\n\n### ERROR ###" . $sql . "\n" . $conn->error . "\n\n";}
+-----+-----------+------------+--------+----------+-----------+-------------+
| id | article | attr1 | attr2 | attr3 | attr4 | attr5 |
+-----+-----------+------------+--------+----------+-----------+-------------+
| 001 | XYZ1 | NULL | NULL | NULL | NULL | NULL |
| 002 | XYZ2 | NULL | NULL | NULL | NULL | NULL |
| 003 | XZY1 | NULL | NULL | NULL | NULL | NULL |
| 004 | XZY2 | NULL | NULL | NULL | NULL | NULL |
| 005 | 8997451 | NULL | NULL | NULL | NULL | NULL |
+-----+-----------+------------+--------+----------+-----------+-------------+
but I would like to have all the attributes in one row:
+-----+-----------+------------+--------+----------+-----------+-------------+
| id | article | attr1 | attr2 | attr3 | attr4 | attr5 |
+-----+-----------+------------+--------+----------+-----------+-------------+
| 001 | 1 | XYZ1 | XYZ2 | XZY1 | XZY2 | 8997451 |
+-----+-----------+------------+--------+----------+-----------+-------------+
I'm pretty sure that my "insert into" is wrong, but I don't know how to fix it.

Answer 1

You have to update your SQL query, it should looks like:
$sql = "
INSERT INTO attributes (article , attr1, attr2, attr3, attr4 , attr5)
VALUES ('$article', '$attr1', '$attr2', '$attr3', '$attr4', '$attr5')
";
$result = $conn->query($sql);
and now you have to have variables $article, $attr1, $attr2, $attr3, $attr4, $attr5 which contains appropriate values.
And when you doing $xx_val = (string) $xx; please don't forget about validate and escape actual value, with purpose to prevent SQL-Injection.

Answer 2

You're forgetting the qoutes around the string values like so:
INSERT INTO attributes (article, attr1, attr2, attr3, attr4, attr5)
VALUES ('$xx_val', '$xx_val', '$xx_val', '$xx_val', '$xx_val', '$xx_val')
