用PHP更新数据库

缺少一个引号：

village=$village'

必须是

village='$village'

---

此外，您还应该使用准备好的语句来防止sql注入，这样可以使查询更具可读性。

请更新您的代码

---

其中id=“$id.”“

您不需要更新查询中的

值（“$name”、“$fathers\u name”、“$gotra”、“$image”、“$village”、“$company\u name”、“$address1”、“$address2”、“$city”、“$pincode>”
中缺少
村=$village'

改变

你应该仔细阅读sql注入。谢谢兄弟，这是一个愚蠢的错误。再次感谢Hanks Hassan。我知道它的价值，但缺少的报价是痛苦的。
$sql = "UPDATE members_data SET name='$name', fathers_name='$fathers_name', gotra='$gotra', image='$image', village=$village', company_name='$company_name', address1='$address1', address2='$address2', city='$city', pincode='$pincode', mobile1='$mobile1', mobile2='$mobile2', village_number='$village_number' )VALUES('$name', '$fathers_name', '$gotra', '$image', '$village', '$company_name', '$address1', '$address2', '$city', '$pincode', '$mobile1', '$mobile2', '$village_number' WHERE id= '".$id."'";

$sql = "UPDATE members_data SET name='$name', fathers_name='$fathers_name', gotra='$gotra', image='$image', village='$village', company_name='$company_name', address1='$address1', address2='$address2', city='$city', pincode='$pincode', mobile1='$mobile1', mobile2='$mobile2', village_number='$village_number' ) WHERE id= '$id' ";
