[RESOLVED] Notice of Undefined index

Php_Beginner2 · Nov 5, 2011

Hi there, I having problem with my dynamic webpages designed with PHP and MySQL. There is a undefined index notice of 'student_name'. The notice is from the highlighted line below.

My codes:

if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "frmedituser")) {
$updateSQL = sprintf("UPDATE student SET student_name=%s, student_ic=%s, student_gender=%s, student_race=%s, student_religion=%s, student_address_c=%s, student_email=%s, `year`=%s, year_intake=%s, program=%s, student_contact=%s, student_address=%s, lect_id=%s, medical=%s, medical_name=%s, medical_relation=%s, medical_contact=%s, medical_address=%s, admin_id=%s, admin_update=%s WHERE student_id=%s",
                       GetSQLValueString($_POST['student_name'], "text"),
                       GetSQLValueString($_POST['student_ic'], "text"),
                       GetSQLValueString($_POST['student_gender'], "text"),

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "frmstuconfirm")) {
  $insertSQL = sprintf("INSERT INTO student (student_id, student_pass, student_update, student_name, `year`, year_intake, program, lect_id, admin_id, admin_update) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)",
                       GetSQLValueString($_POST['student_id'], "int"),
                       GetSQLValueString($_POST['student_pass'], "text"),
                       GetSQLValueString($_POST['student_update'], "text"),
                       GetSQLValueString($_POST['student_name'], "text"),

You're assuming that $REQUEST['student_name'] always exists when this page is requested (and the same for all the other $REQUEST fields).

If it doesn't exist (because it wasn't part of the request), you'll get this message as soon as you try to use it.

In short, check first.

Thanks. I solve that but another index notice shown up. It states my "program" is undefined. The line is highlighted below.

Codes:

<label>
<select style="color: #009; font-family: Verdana, Geneva, sans-serif; font-size: 11px;" name="year" id="year">
<option value="1" <?php if (!(strcmp(1, $REQUEST['year']))) {echo "selected=\"selected\"";} ?>>1</option>
<option value="2" <?php if (!(strcmp(2, $REQUEST['year']))) {echo "selected=\"selected\"";} ?>>2</option>
<option value="3" <?php if (!(strcmp(3, $REQUEST['year']))) {echo "selected=\"selected\"";} ?>>3</option>
<option value="4" <?php if (!(strcmp(4, $REQUEST['year']))) {echo "selected=\"selected\"";} ?>>4</option>
<option value="5" <?php if (!(strcmp(5, $REQUEST['year']))) {echo "selected=\"selected\"";} ?>>5</option>
<option value="6" <?php if (!(strcmp(5, $REQUEST['year']))) {echo "selected=\"selected\"";} ?>>6</option>

Hi,

I have written a code to generate a calendar in php. But my calendar isn't perfect enough as much as I am expected. It show current month, year but not the current day. I wish highlight the current day.

Here is the code for the calendar:

<?php
  $monthNames = Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");

if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");
if (!isset($_REQUEST["year"]))  $_REQUEST["year"]  = date("Y");

  $cMonth = $_REQUEST["month"];
  $cYear  = $_REQUEST["year"];

  $prev_year = $cYear;
  $next_year = $cYear;


$prev_month = $cMonth-1;
$next_month = $cMonth+1;

if ($prev_month == 0 ) {
$prev_month = 12;
$prev_year = $cYear - 1;
  }
 	if ($next_month == 13 ) {
    $next_month = 1;
    $next_year = $cYear + 1;
  }
?>
   <div id="calendar_div" name="calendar_div">
    <table width="200">
        <tr align="center">
          <td bgcolor="#999999" style="color:#FFFFFF">
            	<table width="100%" border="0" cellspacing="0" cellpadding="0">
                    <tr>
                      <td width="50%" align="left">&nbsp;&nbsp;<a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $prev_month . "&year=" . $prev_year; ?>" style="color:#FFFFFF">Previous</a></td>
                      <td width="50%" align="right"><a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $next_month . "&year=" . $next_year; ?>" style="color:#FFFFFF">Next</a>&nbsp;&nbsp;</td>
                    </tr>
              </table>
          </td>
        </tr>
        <tr>
            <td align="center">
              <table width="100%" border="0" cellpadding="2" cellspacing="2">
                <tr align="center">
                  <td colspan="7" bgcolor="#999999" style="color:#FFFFFF"><strong><?php echo $monthNames[$cMonth-1].' '.$cYear; ?></strong></td>
                </tr>
                <tr>
                  <td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>S</strong></td>
                  <td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>M</strong></td>
                  <td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>T</strong></td>
                  <td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>W</strong></td>
                  <td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>T</strong></td>
                  <td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>F</strong></td>
                  <td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>S</strong></td>
                </tr>

            <?php 

            	$timestamp = mktime(0,0,0,$cMonth,1,$cYear);
            	$maxday    = date("t",$timestamp);
            	$thismonth = getdate ($timestamp);

				$startday  = $thismonth['wday'];

              for ($i=0; $i<($maxday+$startday); $i++) {
                if(($i % 7) == 0 ) echo "<tr>\n";
                if($i < $startday) echo "<td></td>\n";
                else echo "<td align='center' valign='middle' height='20px'>". ($i - $startday + 1) . "</td>\n";
                if(($i % 7) == 6 ) echo "</tr>\n";
              }

             ?>

          </table>
        </td>
    </tr>
</table>
</div>

How to make the current day being highlighted automatically as time day passed. I appreciate any help offered. Thanks in advance.
