希望一切顺利。 我正面临一个挑战,经过阅读和搜索,我决定召唤众神。
我的数据库中有一个名为“tclinte”的表,其中包含 Names :
|CliNIF | CliNome | CliNumProc | CliNIC | CliOrigem | CliGestor | CliContactoGC|
CliNIF(主键)和CliNome(单独/不能重复,其余的重要事项)
因此,我想检查在向该表插入数据时,新的CliNIF或新的CliNome是否已经在表中,例如:
if (CliNIF and CliNome exists) { update all fields except them}
else if (CliNIF and CliNome don't exist) { create all fields}
else if (CliNIF exists and CliNome not exists) { update fields except CliNIF}
else { update fields except CliNome}
----------------我有这个,但它只检查CliNIF是否存在,尝试将EXACT与EXi相同,但我收到错误“mysql_fetch_array()期待资源布尔给出“即使它应该工作-------
N.º1检查nif是否存在 - 工作正常 N.º2 - 检查名称是否存在 - 给出错误)
$queryTCliente1 = "SELECT * FROM TCliente WHERE CliNIF =".$_POST['CliNIF'];
$searchTCliente1 = mysql_query($queryTCliente1);
$resultTCliente1 = mysql_fetch_array($searchTCliente1);
if (empty($resultTCliente1)){
//PREENCHIMENTO TABELA CLIENTE
$insertTable= mysql_query("insert into TCliente (CliNIF, CliNome, CliNumProc, CliNIC, CliOrigem, CliGestor, CliContactoGC)
values ( '".$_POST['CliNIF']."', '".$_POST['CliNome']."','".$_POST['CliNumProc']."', '".$_POST['CliNIC']."',
'".$_POST['CliOrigem']."', '".$_POST['CliGestor']."', '".$_POST['CliContactoGC']."');");
}
$queryTCliente2 = "SELECT * FROM TCliente WHERE CliNome =".$_POST['CliNome'];
$searchTCliente2 = mysql_query($queryTCliente2);
$resultTCliente2 = mysql_fetch_array($searchTCliente2);
if (empty($resultTCliente2)){
//PREENCHIMENTO TABELA CLIENTE
$insertTable= mysql_query("insert into TCliente (CliNIF, CliNome, CliNumProc, CliNIC, CliOrigem, CliGestor, CliContactoGC)
values ( '".$_POST['CliNIF']."', '".$_POST['CliNome']."','".$_POST['CliNumProc']."', '".$_POST['CliNIC']."',
'".$_POST['CliOrigem']."', '".$_POST['CliGestor']."', '".$_POST['CliContactoGC']."');");
}
答案 0 :(得分:0)
而不是
"SELECT * FROM TCliente WHERE CliNome =".$_POST['CliNome'];
请试试这个。希望这能解决您的错误
"SELECT * FROM TCliente WHERE CliNome ='".$_POST['CliNome']."'";
