getuser.php

<?php
//$q = intval($_GET['q']);

$con = mysqli_connect('localhost','root','','modem');
if (!$con) {
    die('Could not connect: ' . mysqli_error($con));
}
    if(!isset($_POST['submit'])) {

        $branch = $_POST['branch'];

        $result = mysqli_query($con,"SELECT *, DATE_FORMAT( date, '%M %Y' )as date2
        FROM bm_ibadan_division
        WHERE branch = '$branch'
        ORDER BY date ASC");

        echo "<table align='center'  width='400px' border='1'>
        <tr>

        <th>Amount</th>
        <th>Date2</th>
        </tr>";

         while($row = mysqli_fetch_array($result)) {
          echo "<tr>";
          echo "<td>" . $row['branch'] . "</td>";
          echo "<td>" . $row['status'] . "</td>";
          echo "<td>" . $row['amount'] . "</td>";
          echo "<td>" . $row['date2'] . "</td>";

?>

Answer 1

$con = mysql_connect('localhost','root','','modem');

如果（！$ CON）死（＆＃39;无法连接：＆＃39; .mysql_error（$ con））;

if（isset（$ _ POST [＆＃39; submit＆＃39;]））{

    $branch = $_POST['branch'];

    $result = mysql_query($con,"SELECT *, DATE_FORMAT( date, '%M %Y' )as date2 FROM bm_ibadan_division WHERE branch = $branch ORDER BY date ASC");

    echo "<table align='center'  width='400px' border='1'>
    <tr>
    <th>Branch</th>
    <th>Status</th>
    <th>Amount</th>
    <th>Date2</th>
    </tr>";

     while($row = mysql_fetch_array($result)) {
      echo "<tr>";
      echo "<td>" . $row['branch'] . "</td>";
      echo "<td>" . $row['status'] . "</td>";
      echo "<td>" . $row['amount'] . "</td>";
      echo "<td>" . $row['date2'] . "</td>";
      echo "</tr>";
    }

    echo "</table>";
} 
else
{
    echo "access denied"; 
}

mysqli_close($con);
