Hello, I am trying to use array in bind statement to avoid entering bind manually Below, I set up the array, then imploded the array to insert , on it // to return 1,2,5 , but I got error Warning: mysqli_stmt::bind_param(): Number of elements in type definition string doesn't match number of bind variables $arr = [1,2,5]; $arr_as_string = implode( ',',$arr); $type = 'iii'; $params = [$type,$arr_as_string]; $tmp = []; foreach($params as $key => $value) $tmp[$key] = &$params[$key]; call_user_func_array([$query, 'bind_param'], $tmp);

Is there a way to bind parameters in a select SEPARATELY? I know how to do this in one line, but would like some direction on how to do this one line at a time, OR means to stick that array into the bind_param line where it will work with different array lengths. using mysqli to modify some older code. Understanding of course that the ?'s count must match the amount of parameters. End result to make a generic reader function. $sql = "SELECT ID, foo, bar FROM table WHERE ID = ? AND bar = ?"; $vars[] = array('typ' => "i", 'vlu' => $id); $vars[] = array('typ' => "s", 'vlu' => $rkey); $stmt = $db->prepare($sql); foreach($vars as $var){ $stmt->bind_param($var['typ'], $var['vlu']); } $stmt->execute(); $res = $stmt->get_result(); $rows = $res->fetch_array(MYSQLI_ASSOC);

Hy I'm trying to execute this query $stmt = $mysqli->prepare("SELECT streamer,content,provider FROM evento,canali WHERE canali.id=evento.idcanale AND evento.titolo LIKE '%?%' OR evento.sottotitolo LIKE '%?%' AND evento.datainizio=2013-02-21;"); $stmt->bind_param('ss',$tok,$tok); $stmt->execute(); $stmt->close(); but I get this error Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement. but to me it seems like the number are the same, you can see how I prepared the statement with 2 arguments to define, and then I passe 2 arguments to add_param, what I'm getting wrong? some has some ideas? thanks daniele New php-forum User Posts: 2 Joined: Fri May 03, 2013 6:48 pm

Hi Everyone, I am using the bind_param() function and am building a function around it. I need an automated way of inserting a uncertain (unlimited) amount of parameters into this function. ie have the php code able to insert parameters into the bind_param() function on its own. So if it is given 3 parameters put them in as bind_param($param1,$param2,$param3) or if given 5 parameters bind_param($param1,$param2,$param3,$param4,$param5) I need a way of having the script insert them in for me. What I was thinking was having all of these parameters giving to a function above this as an array. I would then use a foreach loop to determine what type of value each value in this array is and create a string with the appropriate letters to have as the first parameter in the bind_param($value_types ... Then I need a way of cycling through this array and adding how ever many values it has, as individual parameters, to the bind_param() function. Thanks in advance, Timothy

<?php /* create a prepared statement */ if ($stmt = $mysqli->prepare("INSERT INTO userregistry (email,password11,firstname,lastname,contact,sex,dob,active,date) VALUES (?,?,?,?,?,?,?,?,?)")) { /* bind parameters for markers */ $stmt->bind_param("sssssssss", $email , $hash, $firstname , $secondname , $contact , $sex ,$dob , $active , $date); /* execute query */ $stmt->execute(); /* bind result variables */ $stmt->bind_result($email,$hash,$firstname,$secondname,$contact,$sex,$dob,$active,$date); $stmt->fetch(); /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?> Well this is the code I've written to enter the above fields into a DB I keep getting the error Warning: mysqli_stmt::bind_result(): Number of bind variables doesn't match number of fields in prepared statement in D:\xampp\htdocs\bullet2\sqlienterintodb.phpon line 15 Any ideas ??
