If I do: <?php $email = $_POST["mai"]; $nickname = $_POST["nck"]; $mysqli = new mysqli($db_host, $db_username, $db_password, $database); $prepared_statement = "INSERT INTO users VALUES(?,?,?)"; if ($stmt = $mysqli->prepare($prepared_statement)) { $id = ""; $stmt->bind_param("iss",$id,$email,$nickname);

问题 I'm trying to properly prepare my data for $wpdb $region = $wpdb->get_results( $wpdb->prepare( " SELECT tr.*, count(*) AS jobs_count FROM {$wpdb->terms} tr INNER JOIN {$wpdb->term_taxonomy} tm ON ( tm.term_id = tr.term_id ) INNER JOIN {$wpdb->term_relationships} tmr ON ( tmr.term_taxonomy_id = tm.term_taxonomy_id ) INNER JOIN {$wpdb->posts} p ON ( p.ID = tmr.object_id ) WHERE (tm.parent = '%d' AND tm.taxonomy = '%s' AND p.post_type = '%s' ) GROUP BY name HAVING COUNT(name) > '%d' ", 0,

问题 I'm implementing prepared statements on my already working mysqli queries. I'm having trouble with a line if(mysqli_num_rows($result) == 0) as it's now a string instead of a mysqli_result. if($nameAvailableStmt = mysqli_prepare($link, 'SELECT name FROM usetbl1 WHERE name=? LIMIT 1')) { mysqli_stmt_bind_param($nameAvailableStmt, "s", $_POST['dangerous']); mysqli_stmt_execute($nameAvailableStmt); mysqli_stmt_bind_result($nameAvailableStmt, $result); mysqli_stmt_fetch($nameAvailableStmt); } if

问题 Okay, so I've spent a couple days trolling google and finding absolutely nothing on this. Basically I'm using a prepared statement that has a couple joins and matches based on several LIKEs, an IN, and a FREETEXT. I'm building the query dynamically to support the IN condition. I think some code will help public function searchForProjWithTags(Array $dSearchArgs, $dTags) { $bSplitTags = preg_split ("/[,]/", $dTags); $bCount = count($bSplitTags); $bQuestionMarks = "?" . str_repeat (",?", $bCount

问题 I have a List of Strings that I want to set as a parameter in a preparedstatement. This question and answer here, makes it look easy: How to use an arraylist as a prepared statement parameter Well, not really easy.
