Warning: mysqli_stmt_bind_param: Number of elements in type definition string doesn't match number of bind variables

Warning: mysqli_stmt_bind_param: Number of elements in type definition string doesn't match number of bind variables

php bind_param array

I am getting the message "

Warning: mysqli_stmt_bind_param: Number of elements in type definition string doesn't match number of bind variables in…

in a simple php select statement

$wherePtest1 = "postcode= ? AND  proptype = ? AND ";
$whereVtest1 = "$lc_postcode, $proptype";

$where_no_andP = rtrim($wherePtest1, 'AND ');
var_dump($where_no_andP);
var_dump($whereVtest1); 

/* 1. create a prepared statement */
if ($stmt1 = mysqli_prepare($link, "SELECT $what_select4TS FROM $table WHERE $where_no_andP ORDER BY rent $reihenach LIMIT $offset, $rowsPerPage")) 
{
/* 2. bind parameters for markers */
mysqli_stmt_bind_param($stmt1, "ss", $whereVtest1);

/* 3. execute query */
etc

I am getting this warning EVEN THOUGH var_dump() correctly show

string(29) "postcode= ? AND proptype = ?" 
string(9) "da8, Flat"!

Because this:

mysqli_stmt_bind_param($stmt1, "ss", $whereVtest1);
                                           ^^

MySQLi will NOT take your CSV data in $whereVtest1 and split it up for you. You have to EXPLICITLY provide a SINGLE value for EVERY placeholder you have:

mysqli_stmt_bind_param($stmt1, 'ss....s', $val1, $val2, .... $valN);
                                ^----------^
                                 ^------------------^

Php warning: mysqli_stmt::bind_param(): number of elements in , I am experiencing the following error. Warning: mysqli_stmt::bind_param(): Number of elements in type definition string doesn't match number of  mysqli_stmt::bind_param(): Number of elements in type definition string doesn't match number of bind variables warning. My codes for the prevention of SQL injection isn't working.


You have two wrong factors:

  1. Your $whereVtest1 = "$lc_postcode, $proptype"; is a string as it is encapsulated in quotes. The variables (2) are printed into the string. so in effect this variable is just one variable, it is NOT two or more concatenated (which it looks like you where trying to do).

You can not concatenate variables like this, use an array if required.

  1. mysqli_stmt_bind_param($stmt1, "ss", $whereVtest1); this is telling SQL to expect TWO string values (ss), but due to (1) you are giving it just one. This is your error.

To fix:

mysqli_stmt_bind_param($stmt1, "ss", $lc_postcode, $proptype);

This line will now work and marry up the PHP and SQL correctly.
