Question

I have this code

while($row = mysql_fetch_row($result)) { echo '<tr>'; $pk = $row[0]['ARTICLE_NO'];  foreach($row as $key => $value) { echo '<td><a href='#' onclick='GetAuctionData(\''.$pk.'\')'>' . $value . '</a></td>'; } 

which gets pk. pk is then passed on to the axjax part with this:

function GetAuctionData(pk) { ..... var url='get_auction.php?' url=url+'cmd=GetAuctionData&pk='+pk; 

And finally used in a separate php file with:

$pk = $_GET['pk']; $sql='SELECT * FROM Auctions WHERE ARTICLE_NO ='$pk''; 

the second php file works fine when using it by itself and passing parameters. Likewise there are no errors anywhere. The problem seems to be with passing or generating $pk, as the links in the output file result in $pk being incremednted by 2, eg 4, 6, 8 etc

I can not understand why this is happening.

Answer 1

mysql_fetch_row link does not have subarrays. It will return the first field as 0, next as 1, etc.

Try with

$pk = $row[0]; 

This can easily be used with your foreach

while($row = mysql_fetch_assoc($result)) $pk = $row['ARTICLE_NO']; 

or this gives you both associative and numbered array.

while($row = mysql_fetch_array($result, MYSQL_BOTH)) $pk = $row['ARTICLE_NO']; 

EDIT: Based on

$result = mysql_query('SELECT SELLER_ID, ACCESSSTARTS, ARTICLE_NAME FROM {$table}'); 

You have to include the row you want a value from. 😉

$result = mysql_query('ARTICLE_NO, SELECT SELLER_ID, ACCESSSTARTS, ARTICLE_NAME FROM {$table}'); 

BTW: Im pretty sure this nested loop will not produce what you want. You’ll get 3 links to each article_no. The first with seller_id as text, the second text is accessstarts, and the last link with the same href will have the text article_name.

Maybe something like this?

while($row = mysql_fetch_assoc($result)) {     $pk = $row['ARTICLE_NO'];     echo '<td><a href='#' onclick='GetAuctionData(\''.$pk.'\')'>' . $row['ARTICLE_NAME'] . '</a></td>'; }
