Change database from mysql 4 to mysql 5 affects my calendar event page

newphpcoder · October 20, 2010

I changed my database from mysql 4.1.10 to mysql 5.0 and I encountered error in my calendar event page. The output of my calendar date was change instead of date it becomes “>” and also when I press the button to move to another month I can’t move to another month. I have no idea why it happened.

Here is the old calendar code:

<?php
$dbCnx = @mysql_connect("localhost","", "") or die('Could not Connect to the database')
mysql_select_db("mydb");	
?>
<html>
<script>
function goLastMonth(month, year){
if(month == 1){
--year;
month = 13;
}
document.location.href = '<?=$_SERVER['PHP_SELF'];?>?month='+(month-1)+'&year='+year;
}
function goNextMonth(month, year){
if(month == 12){
++year;
month = 0;
}
document.location.href = '<?=$_SERVER['PHP_SELF'];?>?month='+(month+1)+'&year='+year;
} 
function remChars(txtControl, txtCount, intMaxLength)
{
if(txtControl.value.length > intMaxLength)
txtControl.value = txtControl.value.substring(0, (intMaxLength-1));
else
txtCount.value = intMaxLength - txtControl.value.length;
}
function checkFilled() {
var filled = 0
var x = document.form1.calName.value;
if (x.length > 0) {filled ++}
var y = document.form1.calDesc.value;
if (y.length > 0) {filled ++}
if (filled == 2) {
document.getElementById("Submit").disabled = false;
}
else {document.getElementById("Submit").disabled = true} // in case a field is filled then erased
}
</script>
<body>
<?php

$month = (isset($_GET["month"])) ? $_GET['month'] : "";

if(empty($day)){ $day = date("j"); }
if(empty($month)){ $month = date("n"); }
if(empty($year)){ $year = date("Y"); } 
$currentTimeStamp = strtotime("$year-$month-$day");
$monthName = date("F", $currentTimeStamp);
$numDays = date("t", $currentTimeStamp);
$counter = 0;
function hiLightEvt($eMonth,$eDay,$eYear){
$todaysDate = date("n/j/Y");
$dateToCompare = $eMonth . '/' . $eDay . '/' . $eYear;
if($todaysDate == $dateToCompare){
$aClass='class="today"';
}else{

On my new codes I only change the codes for the connection of database like the “host”, ”username”, ”password”, ”database name”, “table name”.

Honestly, I have no idea why it happened after I change my database. Actually my tbluser was work so I connected in my database on my other webpage.

Any help is highly appreciated. Thank you in advance.
