LAST_INSERT_ID call

[TECK]

i want to call in settinggroup the last settinggroupid (for example, 32 that i just created in settinggroup with a NULL). here what i came up with:$settinggroupid=$DB_site->query("SELECT LAST_INSERT_ID() FROM settinggroup");
$DB_site->query("INSERT INTO setting VALUES (NULL,$settinggroupid,'News forum ID','newsforumid','15','The specified forum will contain threads viewed on the main page only.','',0)");it doesnt want to grab it... hmmmm.. i'm upset :noid:

the script returns this:
---------------------------------------
INSERT INTO setting VALUES (NULL,Resource id #6,'News forum ID','newsforumid','15','The specified forum will contain threads viewed on the main page only.','',0)

instead of:
---------------------------------------
INSERT INTO setting VALUES (NULL,32,'News forum ID','newsforumid','15','The specified forum will contain threads viewed on the main page only.','',0)

$settinggroupid=$DB_site->query_first("SELECT LAST_INSERT_ID() FROM settinggroup");

Put the values from the query into an array then it will work

Just use $DB_site->last_insert().

is not working PPN.. it returns Array instead of the value.

FireFly, can you post the exact line please? i need to make a query on this. here it is what i try to do:$DB_site->query("INSERT INTO settinggroup (settinggroupid,title,displayorder) VALUES (NULL,'".addslashes($title)."','$displayorder')");
echo "Adding settinggroup data... Done. <font color='#006699'>settinggroup</font> table populated.<br>\n";

$settinggroupid=$DB_site->query_first("SELECT LAST_INSERT_ID() FROM settinggroup");
$DB_site->query("INSERT INTO setting VALUES (NULL,$settinggroupid,'News forum ID','newsforumid','15','The specified forum will contain threads viewed on the main page only.','',0)");
echo "Adding setting data... Done. <font color='#006699'>setting</font> table populated.<p></td>\n";i need to call the last ID from settinggroup and insert it as a value into setting. let me know where i do it wrong.

Yes it returns an array, thats how you get data from the database, or you fetch row or fetch object.

use $settinggroupid[LAST_INSERT_ID()] as you said its an array. If your ever curious to what value an array holds you can use print_r($array);
and it will print out all the values of $array.

Anyway you can use $DB_site->insert_id(); to use the abstraction layer if you want.

its part of the abstraction layer which simply uses mysql_insert_id(); which is a nice trait of mysql as it gets the last value of the auto incrememnt column.

btw scott, ty for your tips. i learn alot from mysql.com site, but you guys have all kind of tricks.. ;)

[Admin]

The bit of code you posted is correct nakkid.
mysql_insert_id() returns the last auto-increment ID that was insert into the DATABASE during the current connection.

[Scott MacVicar]

use this

$DB_site->query("INSERT INTO settinggroup (settinggroupid,title,displayorder) VALUES (NULL,'".addslashes($title)."','$displayorder')");
echo "Adding settinggroup data... Done. <font color='#006699'>settinggroup</font> table populated.<br>\n";

$settinggroupid=$DB_site->insert_id();
$DB_site->query("INSERT INTO setting VALUES (NULL,$settinggroupid,'News forum ID','newsforumid','15','The specified forum will contain threads viewed on the main page only.','',0)");
echo "Adding setting data... Done. <font color='#006699'>setting</font> table populated.<p></td>\n";
