Ok I got a databased named 'test_DB' and a table inside of that named 'Table1'. Inside of 'Table1' I have 2 feilds 'ID,Entry'.

Now on my php page How would I display a selected entry from its ID number which is from the ID column, and display it?

Thanks, Josh

here, I barrowed this from the MYSQL forum...look harder next time for your answer...

$link = @mysql_pconnect($server, $user, $pwd)

or die("Could not connect: " . mysql_error());


or die ("Could not select database." . mysql_error());

$sql_select = "select * from table ";

$result = mysql_query($sql_select, $link);

if ($result){

echo mysql_num_rows($result) ;


else {

echo ("Problem: " . mysql_error());

In your studying of MySQL you should have atleast learned about the SELECT statements, they are universal throught all dbs as far as I know. Now the SELECT statment you have here is SELECT * where the * reperesents all the information in the table...so if you look for a certain ID you would need something like a WHERE clause to say SELECT * WHERE ID==num or something. Not to positive on teh syntax but that will get the entire row where that ID has the same value as num...does that make sense?

Ive never seen the $link what the hell does that mean?

the $link is basically getting its information elsewhere, in PHP the $link will be a variable with the title link...in our case here its refering to $link = @mysql_pconnect($server, $user, $pwd) so it is making sure that you are connected to the MySQL server... make sense?

It would seem that you don't wish to learn this in which case indicates to me that this could be a school homework assigment where you just want us to give you the answer. If that is the case we are done helping you.

It's not that difficult to understand. You should read through some basic SQL and PHP tutorials. There are plenty of threads that deal with both in these forums so you can use the search feature.

just try this:

//copied and pasted lots of this from phpdev's examples

or die ("could not connect to database, please check that mysql is in fact running");

// as Jason said, the (*) will just select all fields in a table. i've
// selected them separately, don't ask me why

$sql="SELECT ID,Entry FROM Table1"; // the sql statement
$result=mysql_query($sql); // actually executing the query here

//now print out all the IDs and Entries in each row using a loop
for($i=0; $i<mysql_num_rows($result); $i++){
$row_array = mysql_fetch_row($result); //fetch current row
echo("ID: {$row_array[0]}, Entry: {$row_array[1]} <br>");

if you can't get the code by reading it, i'll assume it means that you really haven't done much work with databases/programming. you should get hold of some tutorials.
have you downloaded phpdev? it's got lots of elementary examples to get u up and running.
visit www.php.net and read a bit of the manual (http://www.php.net/manual/en/), www.phpfreaks.com, www.mysql.com.
there are lots more php tutorials (http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=php+tutorials+for+beginners) all over the web.


oops.. a minute late... now if i'd seen spookster's reply first i wouldn't bother here. :rolleyes:
