PHP and Ajax for Login forms

Design a login box like the one shown below



<form  method="post" action="#" name="login" id="login"> 
   <label>Login Id:  
 <input type="text" name="uid" id="uid" tabindex="1" class="text"/> 
   </label> 
  <label>Password:  
 <input type="password" name="pwd" id="pwd" tabindex="2" class="text"/> 
 <img src="images/login.jpg" alt="Login" name="submit" width="76" height="16" id="submit"   onclick="submfrm()" style="cursor:pointer;"  />
 </label> 
</form>

Write the submfrm() function <script language="javascript" type="text/javascript">
function submfrm()
{

var exp1="^[\\w-.]+\\@[\\w.-]+\\.[a-z]{2,4}$";
var exp2="^[0-9a-zA-Z_]*$";
if(document.getElementById("uid").value.match(exp1) &&       document.getElementById("pwd").value.match(exp2))
{
var obj=document.getElementById("uid");
var str = obj.name + "=" + obj.value;

obj=document.getElementById("pwd");
str += "&" + obj.name + "=" + obj.value;
$.ajax({
    type: "POST",
    url: "checklog.php",
    data: str,
    success: function(msg){
      if(msg=="0")
window.location="pagename.php";
else
alert("Inavlid Login Name / Password");
    }
  });
}
else
alert("Inavlid Login Name / Password");
}
</script>
Note: Take care to include the jquery.js file for the Ajax to run successfully

MySQL Programming Help 

MySql Datatype TIME

The datatype TIME stores values in the format of 00:00:00 for eg: 10:23:54


Task: Retrieve the data with only hours and minutes 


select date_format(newstime,'%H:%i') from india_news where news_flg=1


%H,%i is what you need to add.

<?PHP


$file_handle = fopen("mycsv.csv", "r");
$count =0; //count is initialized to 0
while (!feof($file_handle) ) {

     $line_of_text = fgetcsv($file_handle, 1024); //READS THE CSV FILE LINE BY LINE

     $buffer = fgets($file_handle);
      $myar=explode(",",$buffer); //VALUES ARE STORED IN ARRAYS

     array_pop($myar); // removes the last element of an array      

      $count++; //count is incremented so that we can find the row number / loop number 
}

        $newcount = $count;
fclose($file_handle);

$new = $newcount;
$new = $new - 1;
$file_handle = fopen("mycsv.csv", "r");
$count =0;
while (!feof($file_handle) ) {

$line_of_text = fgetcsv($file_handle, 1024); //READS THE CSV FILE LINE BY LINE
$buffer = fgets($file_handle);

$myar=explode(",",$buffer);

$count++; // COUNTS THE NUMBER OF TIMES / ARRAY OF ARRAYS
array_pop($myar);
$result = end($myar);

switch ($count) // When the count number equals the required array row you get the result
{
case $new:
  echo $result;
  break;
}

}

fclose($file_handle);

?>
