Insert multiple values in one column mysql?

Question

I have a table of checkboxes and values, if a user selects a checkbox they select the value of the id in an array called checkedHW for simplicity sake this is what code looks like:

$ids = implode(',',arrayofids); $sql = "insert into table(id, type) values($ids,type); $db->query($sql);

echo query for testing:

"insert into table('id1,id2','type')

I figured that if I loop through this query I could hypothetically do this:

"insert into table('id1','type');" "insert into table('id2','type');"

but I'm not exactly quite sure how to do, any help would be wonderful :)

I actually solved it using:

for($i=0;$i<count(arrayofids); $i++){ $sql = "insert into table(id,type) values(array[$i], 'type'"; $db->query($sql);}

I hope that helps someone and thank you guys for the help!

I just added an int cast and it only inserts a row for the first value — bubbles

You could do something like this:

$base = 'INSERT INTO table (id, type) VALUES ('; $array = array(1, 2, 3, 4); $values = implode(", 'type'), (", $array); $query = $base . $values . ", 'type')"; $db->query($query);

This is what would be getting submitted:

INSERT INTO table (id, type) VALUES (1, 'type'), (2, 'type'), (3, 'type'), (4, 'type')

i was able to solve it without using implode, but thank you for the help!

Both query are completely different

insert into table('id1,id2','type') will insert single row

id1,id2 | type

whereas

insert into table('id1','type');" insert into table('id2','type');"

will insert two rows

id1 | type
id2 | type

so if your id column is int type then you cant run first query

If you have a series of checkboxes, and wanting to insert the values into your table, you could loop through them like this:

<?php $values = array(); foreach ($_POST['field_name'] as $i => $value) { $values[] = sprintf('(%d)', $value); } $values = implode(',', $values); $sql = "INSERT INTO `table_name` (`column_name`) VALUES $values";

This will give you a SQL query similar to:

INSERT INTO `table_name` (`column_name`) VALUES (1),(2),(3),(4)

Hope this help.
