助けが必要です！私はすでに同じ問題を抱えて3日が経ちました。クエリがブール値の真の結果を与えていないことを私は知っています。私はそれが私に何を与えているのかさえ知りません。それが私に与える問題は：
警告：mysqli_prepare（）は、パラメーター2が文字列であることを想定しています。オブジェクトは48行目のC：\ xampp \ htdocs \ caf \ pages\log.phpにあります。
結果を文字列に変換しようとしましたが、問題は次の行に表示される出力にあることがわかりました。
$query_pages_result = mysqli_query($connection, $get_pages_query) or die($myQuery."<br/><br/>".mysql_error());
ですから、誰かが私にこの行が私が望む結果を与えることができるかどうかを確認するのを手伝ってください。それは私がテーブルレコードに何ページあるかを確認することです。前もって感謝します！
