Have you tested the query statement on its own in phpmyadmin or equivalent? You've misspelt original_price - check that it matches what you have in your table.

Have you run your query in something like phpmyadmin or the mysql client with actual values? There is something about your query statement that is causing the error and if you run it directly, you'll get a more meaningful error message. Also you might want to look at the debugging chapter - it offers some useful debugging tips which will save you hours.

Warning: mysqli_stmt_bind_param() [function.mysqli-stmt-bind-param]: Number of elements in type definition string doesn't match number of bind variables in C:\xampp\htdocs\admin\add_dress.php on line 145

 

i replaced the 'designer' in the query with 'designer_id' and now the query isnt giving any error in mysql client but still my web page gives the above error .

mysqli_stmt_bind_param( $stmt, 'isdsss', $designer, $dn, $op, $rp, $c, $d,$i);

In the above statement you have 6 type definitions - 'isdsss' - and 7 variables.

 

I suspect you need to add another d after the first one.

mysqli_stmt_bind_param( $stmt, 'isddsss', $designer, $dn, $op, $rp, $c, $d,$i);

if (isset($_GET['designer_id']) && is_numeric($_GET['designer_id']) ) {

$designer_id = (int) $_GET['designer_id'];

if ($designer_id > 0) { // Overwrite the query:

 

$q = "SELECT designers.designer_id, CONCAT_WS(first_name, middle_name, last_name) AS designer, dress_name, origional_price,our_price, description,

dress_id FROM designers, dresses WHERE designers.designer_id = dresses.designer_id AND dresses.designer_id = $designer_id ORDER BY dresses.dress_name";

 

THis is a part of a code. when i run that page in browser it gives blank page and whae i run the query in mysql it gives an error unknown column 'designer_id' in where clause. what probably is the error? please help
