auto incriment

[curley]

hi i have a prob.

i have a database table with 2 fields and i want them to auto increment.

right the problem is i am using this query

// here we are trying to add a name
if ($action=="addcomment") {




$comment_insert = $DB_site->query("INSERT INTO `name` (`nameid`, `comment`) VALUES (null, '$comment')");

it just updates all the comments to the same one so i end up with loads of the same name???

the thing is if i use it in phpmyadmin and do the same query but change (null, '$comment')"); to this (null, 'trevor')");

it puts a new line in with the id no and trevor

what am i doing wrong ??

if you use INSERT it doesn't update any lines, it inserts a new one, that's why the command is called insert

you should use UPDATE if you want to update

UPDATE name SET(comment='$comment')

You can also use REPLACE INTO instead of INSERT INTO to overwrite existing lines.

ok so if i have you right then the insert one should put a new line in well it does that ok but then i have all the rest of them with the comment in them as well how do i get the rest to stay as they are..

what i get now is this in the picy

how do i get each line to be different

[Xenon]

UPDATE name SET(comment='$comment') WHERE nameid=xx

replace the xx with the nameid of the uptodate line

[curley]

sorry but i dont know what this bit means nameid=xx..

i tried putting $nameid

then tried the last column number (21) but it still overwrites the lot

[curley]

ok i've sorted that bit out, i can now insert new lines with an id no but how do i use it now to display the newest line where i want to but leave the others as they were??

at the mo the only query i can get to work is this

//try name again
$getname=$DB_site->query_first("SELECT comment FROM name WHERE nameid=23");
$name=$getname[comment];

i have to put the id no in and then it wont go to the next one that i type in to put it into the next thread

[Xenon]

$getname=$DB_site->query_first("SELECT comment FROM name ORDER BY nameid DESC LIMIT 1");

[curley]

[curley]
