"Column cn_uso_id cannot be null"

[joãopedropereira 0]

Olá, amigos. A mensagem "Column cn_uso_id cannot be null" aparece quando eu tento inserir uma notícia. No babnco de dados, a opção está not null. O que eu devo alterar no código abaixo para sanar este problema?

 

Muito obrigado!

 

o código:

<?php require_once('../Connections/Curso_d.php'); ?>
<?php
if (!isset($_SESSION)) {
session_start();
}
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";

// *** Restrict Access To Page: Grant or deny access to this page
function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) { 
// For security, start by assuming the visitor is NOT authorized. 
$isValid = False; 

// When a visitor has logged into this site, the Session variable MM_Username set equal to their username. 
// Therefore, we know that a user is NOT logged in if that Session variable is blank. 
if (!empty($UserName)) { 
// Besides being logged in, you may restrict access to only certain users based on an ID established when they login. 
// Parse the strings into arrays. 
$arrUsers = Explode(",", $strUsers); 
$arrGroups = Explode(",", $strGroups); 
if (in_array($UserName, $arrUsers)) { 
$isValid = true; 
} 
// Or, you may restrict access to only certain users based on their username. 
if (in_array($UserGroup, $arrGroups)) { 
$isValid = true;

Imagino o que esse trecho faça:

 

GetSQLValueString($_POST['cn_uso_id'], "int"),
GetSQLValueString($_POST['cn_titulo'], "text"),
GetSQLValueString($_POST['cn_data'], "date"),
GetSQLValueString($_POST['cn_fonte'], "text"),
GetSQLValueString(isset($_POST['cn_status']) ? "true" : "", "defined","1","0"),
GetSQLValueString($_POST['cn_body'], "text"));

Tenta chamar ele antes de dar o INSERT.

 

Se não der certo, tenta imprimir a variavel que armazena a SQL. Caso imprima certo, tente rodar a SQL direto no banco para ver se insere, se não inserir vai acusar um erro.

 

Para o seu id, não seria melhor deixar ele como auto_increment?

 

Posta aew se conseguiu.

Se for auto_increment, não precisa setar como not_null, pois quando for NULL, ele auto incrementa. Bem óbvio minha explicação, né?! :)

Valeu, gente! Desculpe duplicar esta dúvida, mas aproveitando a gentileza dos camaradas, gostaria de tirar uma segunda dúvida com os caros colegas. É que eu não consigo fazer com que apareço mais de uma notícia cadastradas na página index. Ele cadastra as demais, porém não as exibe. qual poderá ser o problema?

Posta o código que utiliza para exibir as notícias na página.
