I dont understand why i get the above error

if($_POST['agentdetailsbtn'] && $_POST['propertynum']) {


$propnumber = $_POST['propertynum'];

echo('<table class="table table-striped" border="1" >'."\n");

$sql = "SELECT Property_number, buildingtype, Address, agent_id FROM property WHERE Property_number = ':propertynumber'";
			$stmt = $pdo->prepare($sql);
			$stmt->execute(array( 
			':propertynumber' => $propnumber
	
			 )); 


  
while ( $row = $stmt->fetch(PDO::FETCH_ASSOC) ) {

echo"<tr class= 'table-success' border='1'><th>";
    echo("Property Number");
    echo("</th><th>");

What I have tried:

$sql = "SELECT buildingtype, Address, agent_id FROM property WHERE Property_number = ':propertynumber'";
$stmt = $pdo->prepare($sql);
$stmt->execute(array(
':propertynumber' => $_POST['propertynum']

Try removing the single quotes around ':propertynumber'. It is supposed to be a parameter key, not a literal value.

You should post this as a solution. :)

I wasn't 100% certain that it was the answer, but thanks I will do so.

PHP

$sql = "SELECT Property_number, buildingtype, Address, agent_id FROM property WHERE Property_number = ':propertynumber'";

The single quotes around ':propertynumber', means that PHP will treat it as a string literal and not as a parameter keyword. Change the code to:

PHP

$sql = "SELECT Property_number, buildingtype, Address, agent_id FROM property WHERE Property_number = :propertynumber";

so the keyword will be recognised as such.
