PHP

<?php require_once('db/connection.php');
$name = !empty($_POST['name']) ? $_POST['name'] : $_GET['name'];
$email = !empty($_POST['email']) ? $_POST['email'] : $_GET['email'];

$query = "insert into admissionform(name,email,mobile,address,enqdetails) VALUES('$name','$email','$mobile','$address','$enqdetails')";
$json_output = array();
if (!mysql_query($query )) {

print(json_encode($json_output));

Answer 1

你忘记了queryString中的=

String queryString ="name="+ name
 +"&email="+email+"&mobile="+mobile+ "&address"+address+"&enqdetails"+enqdetails;

应该是

String queryString ="name="+ name
 +"&email="+email+"&mobile="+mobile+ "&address="+address+"&enqdetails="+enqdetails;

编辑：你应该像这样首先获得字符串

public void onClick(View v)
{
    final EditText name=(EditText) findViewById(R.id.name);
    final EditText email=(EditText) findViewById(R.id.email);
    final EditText mobile=(EditText) findViewById(R.id.mobile);
    final EditText address=(EditText) findViewById(R.id.address);
    final EditText enqdetails=(EditText) findViewById(R.id.enqdetail);

    String zname = name.getText().toString();
    String zemail = email.getText().toString();
    String zmobile = mobile.getText().toString();
    String zaddress = address.getText().toString();
    String zenqdetails = enqdetails.getText().toString();


    ...


    String queryString ="name="+ zname+"&email="+zemail
        +"&mobile="+zmobile+ "&address"+zaddress+"&enqdetails"+zenqdetails;
    String data = DatabaseUtility.executeQueryPhp("Admissionform",queryString);

    ...

}

数据没有使用php在android中存储到数据库中
