使用Oracle数据库11g R2在PHP中显示基于输入值的信息
我有一个简单的表单(main.php),它将输入作为客户的电话号码:使用Oracle数据库11g R2在PHP中显示基于输入值的信息,php,oracle11g,Php,Oracle11g,我有一个简单的表单(main.php),它将输入作为客户的电话号码: <!DOCTYPE HTML> <html> <div style=margin:0 auto align=center > <form action = "options.php" method = "get" /> <p> <h3>Enter Phone Number:</h3>
<!DOCTYPE HTML>
<html>
<div style=margin:0 auto align=center >
<form action = "options.php" method = "get" />
<p> <h3>Enter Phone Number:</h3> <input type = "text" name =
"cust_phone" />
<p> <input type = "submit" value = "Submit" />
</form>
</div>
</html>
我有两个问题:
1.我想在数据库中添加一个新客户,而不是“找不到人”?
2.如何解决这些错误?
我是PHP新手,这只是我的第一段代码。感谢您的帮助。$row没有该记录,因此您无法访问$row[“ID”],因此,首先检查记录是否存在,然后仅访问数据 第二个问题是您的查询,cust_id字段位于两个表中,所以在编写查询时将其与别名一起使用 请尝试以下代码:-
<!DOCTYPE HTML>
<html>
<body> Details of:<?php echo htmlentities($_GET["cust_phone"])."<br>";
$link = oci_connect('hd', 'hd', 'localhost/mydb');
if(!$link)
{
$e = oci_error();
exit('Connection Error' . $e['message']);
}
$query = "select cust_id from customer where cust_phone = :ph_bv";
$stid = oci_parse($link,$query);
$ph = htmlentities($_GET["cust_phone"]);
oci_bind_by_name($stid, ':ph_bv', $ph);
oci_execute($stid);
$row = oci_num_rows($stid);
$cust_id ='';
if($row>0)
{
$rows = oci_fetch_array($stid, OCI_ASSOC);
$cust_id = $rows["ID"];
oci_free_statement($stid);
exit("Person Not Found");
}
?>
<table border = "black" />
<tr>
<th> ADDRESS </th>
<th> AREA </th>
</tr>
<?php
$query1 = "select a.address, a.area from customer c
join customer_address ca on c.cust_id = ca.cust_id
join address a on a.address_id = ca.address_id where c.cust_id =
:id_bv";
$stid1 = oci_parse($link, $query1);
oci_bind_by_name($stid1, ":id_bv", $cust_id);
oci_execute($stid1);
while($row = oci_fetch_array($stid1))
{
echo "<tr><td>" . htmlentities($row["ADRESS"]) . "</td>";
echo "<td>" . htmlentities($row["AREA"]) . "</td></tr>";
}
oci_free_statement($stid1);
oci_close($link);
?>
</table>
</body>
</html>

它对现有电话号码给出了错误的结果。\u否。它不会为现有电话号码返回任何行。即使对于现有pnoe编号,“oci_num_rows”=0。请告诉我如何将CUST_ID的值存储在第一次查询检索到的变量中,即“从客户处选择CUST_ID,其中CUST_phone=:ph_bv”。所有输入的结果仍然相同。查询在sql*plus中运行良好。我想问一件事,什么是$rows[“ID”]。它有什么价值?它是来自我的数据库的列名,因为我在数据库中的列是“cust_id”。Yes id应该是列名。我以为这是专栏,所以更新后的代码没有改变,我知道了。我发布了一个答案,我认为它是正确的。过来看。
